Abstract

A new species of Sesiidae, Carmenta brachyclados Sterling & Lees, 2024 is described from adult specimens, pupal exuviae and larval borings which were accidentally transported to South Wales, United Kingdom. DNA barcoding and morphological evidence shows that this species is native to the Neotropics, where it feeds in the seedpods of the leguminous tree, Mora excelsa Benth. (Fabaceae: Caesalpinioideae) and that it is related to a group of seed-feeding species of clearwing moths within the genus Carmenta Edwards, 1881, naturally occurring in the Neotropics and southern Nearctic, although C. mimosa Eichlin & Passoa, 1984 has been introduced in Australia and elsewhere as a biological agent.

Carmenta brachyclados sp. nov.; 11. Holotype ♀ dorsal; 12. Holotype ♀ ventral; 13. External diagnostic characters of C. brachyclados;
14. External diagnostic characters of C. whitelyi;
15. Paratype of C. brachyclados ♀ genitalia slide number NHMUK014332461; 16. Paratype of C. brachyclados pre-genital abdomen.

Scale bars: 10 mm (11, 12, 16); 1 mm (15).

 Carmenta brachyclados Sterling & Lees, sp. nov.

Diagnosis: Hindwing with branch of M3 and CuA1 very short (1/10th of distance between edge of discal cell and termen), forewing with discal spot narrow and tapering below M3 towards dorsum, exterior transparent area elongate, with moderately convex outer margin, apical area predominantly black, reaching close to branch of R4 and R5, entire area between stalks of R4 and R5 scaled black (Figs 11–13). Similar to C. whitelyi (See Similar species) but differs in length of branch of M3 and CuA1 in hindwing and in shape of discal spot and exterior transparent area (Figs 13, 14). Female genitalia with sclerotised section of ductus bursae long and thin, ductus seminalis arising at juncture of sclerotised and membranous section of ductus bursae (Fig. 15).

Etymology: The specific name is derived from brachys (gr.) short; klados (gr.) a branch. The species is named after the characteristic short branch of M3 and CuA1 in the hindwing.

 Abstract 

Marine flatworms in Pseudocerotidae Lang, 1884 are known as one of the most abundant groups among polyclads so far. To date, there have been specimen-based records of 36 named species in 5 genera in this family from Japan. The species of Nymphozoon Hyman, 1959 (Polycladida, Pseudocerotidae) are widely distributed in the Indo-Pacific Ocean, but the only known report of the genus in Japan is based on a photo of Nymphozoon orsaki (Newman and Cannon, 1996) taken in the Okinawa Islands. In this paper, we describe a new species from Japanese shallow waters, Nymphozoon cinderella sp. nov., which is characterized by having (1) square-shaped pseudotentacles with broad, black- colored edges and white tips, (2) dull grayish or brownish dorsal coloration, (3) a narrow brown-to-black line encircling the body periphery, and (4) a wide grayish dorsal middle band fringed with a brown-to-black line. Despite that the observed color pattern clearly distinguishes the new species from N. orsaki collected in Papua New Guinea, the p-distance based on partial (942 bp) 28S rDNA gene sequences (1.27%) was comparable to the intraspecific range for pseudocerotids. Further analyses based on more rapidly evolving genetic markers such as cytochrome c oxidase subunit I would probably be required to provide enough support to the molecular distinction between these two species having obviously different body color patterns.

Highlights: 

• The usefulness of female genitalia as diagnostic character in Talanga since their signa structures are species specific.

• A new endemic species Talanga horake is a new to science.

• An identification key of Indonesian Talanga based on external morphology and female genitalia characters.

Abstract

Six species of the genus Talanga Moore 1855 are re-described based on both morphological and genitalia characters. T. tolumnialis Walker is not included due to the lack of available of material. Morphological characters such as a tapering, oblique outwardly antemedial band on the forewing and two black metallic spots externally bordered by similar minute interciliar spots on the hindwing, are proposed as the most appropriate characters to define the genus Talanga. The study also reveals that certain genitalia characters, such as a spatula-shaped uncus, a simple valva with a medial rod-like plate, a long cylindrical phallus without cornuti, a bundle of pencil hairs at the coremata base in male genitalia, and a pair of ovate or circular signa medially bearing denticles in female genitalia, are also diagnostic of this genus. The description of a new endemic species from Foja Mountain, Talanga horakae sp. nov., is presented, as well as an identification key to Indonesian species, and images of adults and genitalia of the studied species.

Diagnosis. The female of Talanga horakae, sp. nov., can be easily distinguished from allied species within the genus Talanga by the presence of a simple crown distad to the black medial band on the forewing, and a dark brown, curved, oblique line, running from the distad M1 to CuA2 on the hindwing (Fig. 2C; black arrows). Diagnostic characters of the female genitalia include a pair of ovate signa with scattered blunt denticles medially, dense sharp denticles along the margin, ...

Abstract

Berdmore’s narrow-mouthed frog, Microhyla berdmorei (Blyth, 1856), is the largest member of the genus Microhyla and is distributed all over Southeast Asia, from Northeast India and southern China to Sumatra and Borneo in Indonesia. Here we demonstrate that M. berdmorei represents a complex of four species that are morphologically, acoustically, and genetically distinct from each other, and we implement taxonomic revisions. Phylogenetic analyses of three mitochondrial DNA (hereafter mtDNA, including COI, 12S, and 16S rRNA; 3119 bp) and one nuclear (BDNF; 716 bp) gene sequences are corroborated by phylogenomic analyses of 2700 ddRAD-seq loci (387,270 bp). All support that the M. berdmorei complex, which originates from the early Miocene (ca. 19.7 mya), consists of two clades that we date to the late Miocene (ca. 7.5 mya). The first clade, which regroups populations of large-sized individuals, is distributed in Indo-Burma and includes a lineage from Northeast India, Bangladesh, and Myanmar (M. berdmorei sensu stricto) and a lineage from West Malaysia, Thailand, Laos, Cambodia, and Vietnam (for which we propose to resurrect the species M. malcolmi Cochran, 1927). The second clade, which regroups populations of small-sized individuals, occurs in Sundaland and also includes two lineages for which we provide taxonomic descriptions on species rank. The first new species is widely distributed from Peninsular Malaysia to the islands of Borneo and Sumatra (described herein as M. sundaica sp. nov.), while the second one is restricted to the Malay Peninsula and occurs in extreme southern Thailand and adjacent Malaysia (M. peninsularis sp. nov.). We further provide evidence for the synonymy of Callula natatrix Cope, 1867 with M. berdmorei sensu stricto, and M. fowleri Taylor, 1934 with M. malcolmi. Our study illustrates the high diversity of Southeast Asian amphibians, especially in the genus Microhyla, which presently totals 54 species.

[Ichthyology • 2024] Microphysogobio punctatus • Redescription of Microphysogobio tungtingensis (Nichols, 1926) with the Description of A New Species of the Genus (Cypriniformes: Gobionidae) from southern China

Microphysogobio punctatus 

Sun, Tang & Zhao, 2024 

DOI: 10.3897/zookeys.1214.127061

Abstract

Although Microphysogobio tungtingensis (Nichols, 1926) has been treated valid since it was described, its morphology remains vague, especially when comparing it with another similar species, M. elongatus (Yao & Yang, 1977). In this study, the types of both species were examined and also compared with several lots of specimens from a wide geographical range: there is no significant difference in morphology between them. Additionally, molecular evidence supported by mitochondrial gene sequence also showed low genetic distance in between. Thus, it is suggested that M. elongatus is a junior synonym of M. tungtingensis. While revising these two species, a new species, Microphysogobio punctatus sp. nov., was discovered that has a similar distribution with them both. However, it can be distinguished from its congeners by having a globular or oval shaped posterior air-bladder chamber which length 58.6%–82.8% of eye diameter; a narrow upper jaw cutting edge which less than half mouth width; a slender caudal peduncle with depth 34.6%–48.5% of length; and a six-branched-ray anal fin. This new species also has numerous small black spots on all fins which is also unique. The new species is morphologically and molecularly close to M. bicolor (Nichols, 1930).

 Microphysogobio punctatus sp. nov.

Diagnosis: This new species can be distinguished from its congeners by a combination of the following characteristics: Posterior chamber of air-bladder small, globular or oval shaped, length 15.8%–26.4% of head length, and 58.6%–82.8% of eye diameter; upper jaw cutting-edge narrow, width less than half mouth width; caudal peduncle slender, depth 34.6%–48.5% of length; lateral-line scales 37–40 (mode 38, mean 39); circumpeduncular scales 12; branched anal-fin rays 6; midventral region of body scaleless only before pectoral-fin base end; all fins with numerous small black spots.

Etymology: The new species name punctatus is derived from the Latin punctum, meaning spot. The name refers to the numerous black spots on its scales and fin rays. Suggested Chinese name for this species is “斑点小鳔鮈”.

Abstract

Stable upland habitats in arid zone biomes are often characterised by locally endemic lineages. Explanations for this pattern include habitat or substrate specialisation (ecological specialisation) or intensifying aridity driving retreat into climatically buffered habitats (climatic refugia). Here we present an analysis of these alternative models using genetic, morphological and climate data for Diplodactylus galeatus, a gecko from central Australia that occurs in a series of isolated populations associated with dissected tablelands and mountain ranges. Analyses of mtDNA and SNP data support four distinct lineages, and dating analyses suggest divergence through the Pliocene. Morphological data show slight differences across lineages. Investigation of climate niche shows that two lineages are restricted to areas more arid than the intervening uninhabited region. These data suggest that specialisation to rocky substrates, potentially with subsequent paleo-erosion of dissected tablelands after a Pliocene wet pulse, was the key driver of divergence in this clade. Based on their deep genetic divergence, and differences in morphology and pattern, we recognise two isolated populations as new species.

Abstract

A new species of the Amolops monticola group is described from Yunnan Huanglianshan National Nature Reserve, southern Yunnan, China. Morphologically, the new species is characterized by a moderate body size (snout–vent length 38.3–40.8 mm in adult males and 62.3–63.1 mm in adult females), head being longer than wide, nostril to snout tip distance being slightly smaller than eye to nostril distance, the presence of pineal body, distinct tympanum, vomerine teeth being invisible in males and weak but visible in females, distinct dorsolateral folds, the absence of outer metatarsal tubercle, the presence of vocal sac and nuptial pad in adult males, dorsal surface of head and body being green with no or a few black dots, and the presence of a few large flat white tubercles on the posterior inferior flank. Genetically, the uncorrected genetic distance between the new species and other species of the A. monticola group ranged from 3.0% to 7.6% in 16S ribosomal RNA and from 7.2% to 17.1% in NADH dehydrogenase subunit 2 gene sequences. Currently, the new species is known only from its type locality in Lvchun County, Honghe Prefecture, Yunnan Province, China.

Amolops huanglianshanensis sp. nov.

Diagnosis. The new species is assigned to genus Amolops based on the presence of enlarged digital discs, circummarginal groove on the discs of fingers, well-developed webbing between toes, and the absence of webbing between fingers. It is further assigned to the A. monticola group based on having smooth skin, side of the head dark with a light-colored upper lip stripe extending to the axilla, and distinct dorsolateral folds. It can be distinguished from other species in the A. monticola group by having a combination of the following characters: Body size moderate, SVL 38.3–40.8 mm in adult males and 62.3–63.1 mm in adult females; head longer than wide; nostril to snout tip distance slightly smaller than eye to nostril distance; internarial distance greater than ...

Etymology. The specific epithet is named for the type locality Yunnan Huanglianshan National Nature Reserve. We suggest the English common name “Huanglianshan cascade frog” and the Chinese common name “黄连山湍蛙 (Pinyin: huáng lián shān tuān wā)”.

Abstract

A new genus and species of lysiosquilloid mantis shrimp is described from Australia and Japan. It is unique in Stomatopoda by its unusual telson ornamentation in which the short intermediate and lateral primary teeth, accompanied by a row of short, graded serrations inward of the intermediate teeth, partially overhang a row of minute submarginal denticles. Although distinctive as a new genus and species, Incertasquilla chimera gen. et sp. nov. does not fit clearly into existing lysiosquilloid families as currently diagnosed and, in some respects, shares a mosaic of features present in several families. Incertasquilla chimera gen. et sp. nov., however, currently fits best into Tetrasquillidae, where it is tentatively placed, although further phylogenetic study may show it belongs in a separate family altogether. In the light of the new character combinations presented by the discovery of Incertasquilla chimera gen. et sp. nov., a revised diagnosis for Tetrasquillidae and updated key to the genera are provided. The discovery of Incertasquilla chimera gen. et sp. nov. expands the described lysiosquilloid fauna to 14 genera and 30 species in Australia, and 10 and 16 in Japan, respectively.

Abstract

This study describes a new species, Sinocyclocheilus xiejiahuai sp. nov., discovered within a cave located in Hongguo Town, Panzhou City, Guizhou Province, southwestern China, with the type locality in the Nanpanjiang River basin. Phylogenetic trees reconstructed based on mitochondrial genes show that the new species represents an independent evolutionary lineage with large genetic differences, 1.9%–13.8% in mitochondrial Cyt b, from congeners. Morphologically, this species can be differentiated from the 79 species currently classified under the genus Sinocyclocheilus by several characteristics: absence of horn-like structures and indistinct elevation at the head-dorsal junction, absence of irregular black markings on the body lateral and scaleless, eyes large, eye diameter 13% of head length, dorsal-fin rays, iii, 6½, last unbranched ray strong, with serrations along posterior margin, pectoral-fin rays, i, 13, anal-fin rays, iii, 5, pelvic-fin rays, i, 7, lateral line pores 74, gill rakers well developed, nine on first gill arch, pectoral fins short, tip not reaching to pelvic-fin origin. The number of Sinocyclocheilus species has been increased from 79 to 80 since the description of this new species.

Diagnosis: Sinocyclocheilus xiejiahuai sp. nov. can be distinguished from all other congeners by the following combination of characters: (1) absence of horn-like structures and indistinct elevation at the head-dorsal junction; (2) absence of irregular black markings on the body lateral and scaleless; (3) eyes large, eye diameter 13% of head length; (4) dorsal-fin rays, iii, 6½, last unbranched ray strong, with serrations along posterior margin; (5) pectoral-fin rays, i, 13; (6) anal-fin rays, iii, 5; (7) pelvic-fin rays, i, 7; (8) lateral line pores 74; (9) gill rakers well developed, nine on first gill arch; (10) pectoral fins short, tip not reaching to pelvic-fin origin (Table 5).

Etymology: The specific name xiejiahuai is in honor of Professor Jia-Hua Xie (谢家骅), for his contribution to zoological research in China. Before retiring from Guizhou Normal University, he described S. angustiporus, the first species distributed in Guizhou within the S. tingi species group, and his work has been an important contribution to the study of zoology in Guizhou, especially the conservation of critically endangered species. We propose the common English name “Xie’s Golden-lined Fish” and the Chinese name “Xiè Shì Jīn Xiàn Bā (谢氏金线鲃).”

Abstract

Opsariichthys iridescens sp. nov. is described from the Qiantang and Oujiang rivers in Zhejiang Province and a tributary of the Yangtze River adjacent to the Qiantang River. It is distinguished from congeners by the following combination of morphological features: no obvious anterior notch on the tip of the upper lip; 45–52 lateral-line scales; 18–21 pre-dorsal scales; two rows of pharyngeal teeth; a maxillary extending to or slightly beyond the vertical anterior margin of the orbit in adult males; a pectoral fin extending to the pelvic fin in adult males; nuptial tubercles on the cheeks and lower jaw of males, which are usually united basally to form a plate; uniform narrow pale pink cross-bars on trunk and two widening significantly on caudal peduncle. Its validity was also supported by its distinct Cyt b gene sequence divergence from all congeners and its monophyly recovered in a Cyt b gene-based phylogenetic analysis.

Diagnosis: The new species, Opsariichthys iridescens sp. nov. can be clearly distinguished from its two sympatric congeners in the Qiantang River and nearby geographic regions (Tables 3, 4). It can be distinguished from O. evolans by the following features: (1) lateral-line scales 45–52 (vs 42–45); (2) scales above lateral-line nine or ten (vs 8); (3) pre-dorsal scales 18–21 (vs 15–17); (4) two rows of pharyngeal teeth (vs 3 rows); (5) maxillary extending to or slightly beyond the vertical of anterior margin of orbit in adult male (vs never extending to the vertical of anterior margin of orbit); (6) pectoral fin extending to pelvic fin in adult male (vs extending far beyond origin of ventral fin); (7) almost uniform narrow pale cross-bars on trunk and widening significantly on caudal peduncle (vs gradually widened, Fig. 3E, F); (8) lower jaw with one row of large tubercles usually united basally to form a plate in male (vs 1 row of moderate tubercles well separated). The new species can be clearly distinguished from O. bidens by the following features: (1) absence of distinct anterior notch on upper lip (vs presence of conspicuous anterior notch on upper lip); (2) two rows of pharyngeal teeth (vs 3 rows); (3) maxillary extending to or slightly beyond the vertical of anterior margin of ...

Etymology: Iridescens is the Latin form of the word iridescent. Here, it refers to the unique body color, which is brighter than that of any known species in the genus. In this study, we propose the Chinese common name Hóng Cǎi Mǎ Kǒu Yú (虹彩马口鱼).

A new highly troglomorphic and diminutive swamp eel inhabiting muddy subsoil in remnants of a tropical rainforest in the Caribbean versant of Costa Rica is described. Comparative anatomical and mitogenomic data support the distinctiveness of the new species and its placement in the genus Ophisternon. The new species is unique among Neotropical congeners in having: 1) a greatly elevated number of precaudal vertebrae, 2) proportionally longer and larger premaxillary, dentary, palatine, and ectopterygoid teeth, 3) palatine and ectopterygoid teeth in a single row, and 4) a small, narrow, and crescent-shaped gill membrane opening. A novel phylogenetic hypothesis of synbranchid relationships proposed herein, derived from comparative mitogenomic data, adds to a body of evidence demonstrating that Ophisternon is not monophyletic (with respect to Synbranchus). This phylogeny, however, strongly supports the monophyly of Neotropical Ophisternon, with the new species resolved as sister to a clade consisting of Ophisternon infernale + Ophisternon aenigmaticum. A pattern of northwestern lineage dispersal and cladogenesis within the Neotropical clade of Ophisternon after its divergence from Synbranchus is inferred from our phylogenetic results and present-day species distributions. Our findings also reinforce the notion that the classification of synbranchid fishes is in dire need of a systematic and comprehensive revision, particularly with respect to the limits and composition of the genera with presence in the Neotropics.

Diagnosis.— Ophisternon berlini is assigned to the genus Ophisternon by having a pectoral girdle connected to the skull by a forked posttemporal joining the supracleithrum at the level of the third vertebra vs. posteriorly displaced to the level of the fifth vertebra with posttemporal reduced to a simple rod and disconnected from the supracleithrum in Synbranchus (Fig. 4) and a branchiostegal membrane opening slit-like vs. small pore-like in Synbranchus (Fig. 5). Ophisternon berlini is unique among its Neotropical congeners in having: 1) an elevated number of precaudal vertebrae: ∼100 vs. ...

Etymology.— The specific epithet (a noun in the genitive case) is a patronym honoring Mr. Erick Berlin, a strong supporter of conservation and scientific research of Costa Rican biodiversity, discoverer of the population of swamp eel herein formally described, and owner of La Brisas, a private nature reserve that contains the type locality of the new species.

Abstract 

We describe a new species of leaflitter frog of the genus Noblella from southern Ecuador, province of Zamora Chinchipe. The new species is diagnosed from all its congeners by having one or two tubercles on the upper eyelids; distal phalanges strongly T-shaped; phalangeal formula on hands 2-2-3-3; phalangeal formula on feet 2-2-3-4-3; heel with a small subconical tubercle; disc on all toes with papillae; dorsum brown or brown with gray, with V-shaped inverted or scattered irregular darker marks. We include a detailed description of its osteology and a study of its phylogenetic relationships. Finally, we evaluate its conservation status and discuss the threats that are currently impacting at the type locality.

Noblella arutam new species

Proposed standard English name. Arutam Leaflitter Frog

Proposed standard Spanish name. Rana de Hojarasca de Arutam

Definition. Noblella arutam sp. nov. (Figure 4–7) differs from its congeners by the following characteristics: (1) skin of dorsum shagreen, with scattered low tubercles more evident on flanks; skin on venter smooth, discoidal fold present, thoracic fold slightly defined; (2) tympanic annulus and membrane defined and visible externally, supratympanic fold slightly defined; (3) snout subacuminate in dorsal view, rounded in lateral view; (4) upper eyelids bearing one or two inconspicuous tubercles; (5) vomerine teeth absent; (6) vocal slits and external vocal sac present, nuptial pads absent; (7) fingers not expanded distally, finger tips acuminate more evident on Finger III, papilla ...

Diagnosis. Noblella arutam sp. nov. can be easily distinguished from all other species currently assigned to Noblella by the following combination of characters: upper eyelids bearing one or two inconspicuous tubercles, distal phalanges strongly T-shaped, phalangeal formula on hands 2-2-3-3, phalangeal formula on feet 2-2-3-4-3, heel with a small subconical tubercle, disc on all toes with papillae, more evident in toes II–IV and dorsum light brown, light brown with gray or dark brown, with V-shaped inverted or scattered irregular darker marks. Similar to the new species, N. naturetrekii and N. personina (Harvey et al., 2013) occur in the eastern slopes of the Andes of Ecuador. Noblella arutam sp. nov. differs from N. naturetrekii (characters in parentheses) by the presence of three ...

Etymology. Noblella arutam sp. nov. is named in reference to Arútam, the spiritual entity symbolizing divine power in the world of the Shuar. The Shuar people are native to western Amazonia, spanning Ecuador and Peru. Several Shuar communities reside in the Cordillera del Cóndor and its immediate surroundings, where this new frog species also inhabits. Arútam is believed to dwell in waterfalls, rivers, mountains, rocks, trees, and certain plants and animals (Delgado, 1986; Pellizzaro, 2005). This deep association highlights the profound connection between nature and the Shuar people. Through this name, we pay tribute to the Shuar people living near the type locality of Noblella arutam sp. nov., their ancestral lands and culture, acknowledging their tireless efforts and commitment to nature protection.
