Abstract

Metagentiana jiangyouensis, a new species of Gentianaceae from Sichuan, China, is described and illustrated. This new species is similar to Metagentiana villifera, but differs by the fact that the plant is glabrous and has 1–4 flowering stems, well-developed basal vegetative rosettes, a pale purple corolla with dark purple spots on the tube and erose or denticulate, non-fringed plicae margins. It also somewhat resembles M. rhodantha, but can be easily distinguished by having shorter stems, entire leaf margins, smooth, shorter sepal lobes, spotted corolla tubes, non-fringed plicae and narrowly winged seeds.

Abstract

Gastrochilus balangshanensis, a new orchid species from the Balang Mountain, Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G. affinis, but differs in having shorter stems, a reniform epichile and a sub-hemispherical hypochile (spur), obtuse-rounded at the apex. The results of molecular phylogenetic analyses based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA markers (matK, psbA–trnH, psbM–trnD and trnL–F) from 50 Gastrochilus species indicate that G. balangshanensis is closely related to G. heminii and G. bernhardtianus, also endemic to the Hengduan Mountains. The novelty is a branch and trunk epiphyte in mixed coniferous forest.

Diagnosis: Gastrochilus balangshanensis is most similar to G. affinis, but can be distinguished by its shorter stem (1.5–3.5 vs. 3.0–12.0 cm), nearly elliptic leaves (vs. oblong-lanceolate to subspathulate), larger sepals (5.6–6.4 × 4.8–5.2 vs. 3.0–5.0 × 1.0–1.3 mm) and petals (5.0–5.8 × 4.0–4.4 vs. 3.0–4.0 × 1.0–1.3 mm), reniform epichile (vs. subtriangular) and sub-hemispherical hypochile, obtuse-rounded at the apex (vs. hypochile obconical, subacute to obtuse and shortly bifid at apex).

Etymology: Its specific epithet refers to the Balang Mountain, type locality of this new orchid. A Chinese name, “ba lang shan peng ju lan” (巴朗山盆距兰), is suggested here.

Abstract

Alysicarpus littoralis Satthaphorn & Leerat. (Fabaceae, Desmodieae), a species confined to Samui Island, Surat Thani province, southern Thailand, is described and illustrated as a species new to science. Initially identified as A. vaginalis (L.) DC., the re-examination of morphological characters revealed distinctions of A. littoralis such as the length of inflorescence internode, length of calyx lobes, the colour of corolla and the type of pods at maturity. The newly proposed species is sometimes similar to A. monilifer (L.) DC. And A. ovalifolius (Schumach.) J. Léonard as it exhibits moniliform pods and lax inflorescence, respectively. The conservation status of the new species is assessed as Critically Endangered (CR, B2(bii+ciii)) following IUCN conservation guidelines since populations are surrounded by human disturbances. A morphological description, line drawing and updated key to species of Alysicarpus in Thailand are presented.

Diagnosis.— Alysicarpus littoralis superficially resembles A. vaginalis in its herbaceous habit, unifoliolate leaves, pseudoracemose inflorescence, valvate calyx and erect loment pods (Fig. 3). However, A. littoralis is distinguishable by longer petiolules (1–1.5 mm long vs ca. 0.3 mm long in A. vaginalis), longer inflorescence internodes (8–12 mm long and lax-flowered vs 2–5 mm long and compact-flowered), longer calyx lobes (3–5 mm long vs 2.3–3 mm long), two-tone-coloured corolla (orangish-yellow standard but pink wings vs monotone-coloured-pink to purple in all petals) and moniliform pods with barrel shaped articles at maturity (vs terete pods with cylindrical articles).

Etymology.— The specific epithet refers to its habitat which can be found in coastal areas.

Vernacular.— Thua lisong na samui (ถั่วลิสงนาสมุย).

 DOI: 10.17129/botsci.3404 

 Researchgate.net/publication/378353472

Abstract

Background: Hechtia is characterized by its terrestrial, succulent rosettes, dioecy, and unisexual, dimorphic flowers, mainly fragrant. The paucity and fragmentary herbarium material limit the species recognition but living material reveals diagnostic characters to delimitate them.

Hypothesis: Hechtia species are circumscribed by a combination of vegetative and floral characters of both sexes. If the new taxon does not share morphological characters with other species, it will be described as new.

Taxon: Hechtia.

Study site and dates: Chamela-Cuixmala Biosphere Reserve, Jalisco, 1985-2023.

Methods: Field collected, cultivated as well as herbarium material of the new taxon were analyzed and compared to other species from the Pacific Lowlands and adjacent areas, particularly flowers of both sexes, fruits, and seeds. Conservation status using IUCN criteria is reported for the new species.

Results: Specimens of Hechtia chamelensis have been misidentified as H. laevis and H. reticulata (both described from fruiting, fragmentary specimens) but the fruit and seed features of both taxa do not match those of the new species. H. chamelensis is known from the Chamela-Cuixmala Biosphere Reserve and it is characterized by strict sympodial growth pattern, green leaves with red hues, shiny and glabrous above, white lepidote below, panicles usually simple to (rarely staminate ones) 2-divided, staminate flowers pinkish to pale white, pistillate with pale green to white petals.

Conclusions: Vegetative and reproductive features as well as geographical distribution allow the recognition of H. chamelensis as a new species native from Jalisco, Mexico.

Diagnosis. This new species differs from Hechtia reticulata in the following characters: fruits 5-6 per each 5 cm length (vs. 8-2 fruits), reticulate (vs. smooth), seeds ca. 1 mm long (vs. 3 mm), inflorescence branches 10-15 cm long vs. 10-12 (-25) cm long). H. laevis has branches with many fruits (40-50 in each 5 cm length) while H. chamelensis only has 5-6 fruits in each 5 cm length, primary inflorescence branches have no stipe nor primary bracts (vs. 2.5-4cm long in H. chamelensis and primary bracts triangular, long-acuminate, 3-4.5 cm long, 4-10 mm wide, longer to equaling the length of the stipe). The new taxon also shows staminate flowers 6-8 mm long, 7-9 mm diameter, petal sapically white, basally pink, widely spread; pistillate flowers 3 mm long, ca. 1 mm diameter; with white petals and sepals basally green apically brown, adnate to the ovary.

Abstract

Two new African minnow species, Enteromius cerinus sp. nov. and Enteromius ruforum sp. nov., are described for science from the Angadiko River, a left-bank sub-affluent of first order of the Nepoko River, draining the north-eastern part of the Okapi Wildlife Reserve (OWR). Both new species belong to the group of Enteromius for which the last unbranched dorsal-fin ray is flexible and underrated. Within this morphological group, both are most similar to Enteromius kamolondoensis, especially in life colour pattern characteristics. However, Enteromius cerinus sp. nov. differs from E. kamolondoensis by its low number of circumpeduncular scales, 10–11 (vs. 12), low maximum body depth, 22.8%–25.7% standard length (Ls) (vs. 26.1%–30.0%), and long anterior and posterior barbel lengths, 32.6%–35.3% head length (LH) (vs. 23.6%–27.2%) and 41.6%–43.9% LH (vs. 30.3%–34.9%), respectively. Further, E. ruforum sp. nov. is also easily distinguished from E. kamolondoensis by its high maximum body depth, 30.6%–33.3% Ls (vs. 26.1%–30.0%), and small, isometric, eye diameter, 26.2%–28.0% LH (vs. 29.1%–31.9%). A barcoding study (mtDNA, cytochrome oxidase subunit I [COI]) revealed that specimens of both new species form lineages well differentiated from those of other available species. As such, (i) E. cerinus sp. nov. diverges from E. kamolondoensis by a K2P genetic distance (GD) of 10.3% and (ii) E. ruforum sp. nov. by a K2P GD of 11.2%. To the present day, the fish fauna of the left-bank sub-affluents of the Nepoko River, in general, remains poorly known or undocumented. Unfortunately, at the same time, multiple anthropogenic impacts are affecting this fauna, such as (i) the destruction of habitats along the river banks for agriculture and fishing and (ii) the use of illegal fishing practices, such as fishing with plant-based ichthyotoxins during ecopage, which is combined with dam building. As a result of the demographic growth, this ecopage results in overfishing and thus is threatening both new species in particular, but all other co-occurring fish species as well. Both new species, E. cerinus sp. nov. and E. ruforum sp. nov., should thus be considered Vulnerable (VU) according to IUCN criterion D2. It is therefore hoped that their discovery highlights the urgent need for a better protection and further in situ exploration of the reserve's freshwater (fish) biodiversity, in general, and that of those small sub-affluents, in particular.

Abstract

The genus Micryletta is widely distributed in South China and Southeast Asia. Although significant progress has been made in the diversity and taxonomy of this genus over the past few years, the distribution range and taxonomy of some species still remain controversial, especially in M. inornata sensu lato. Consequently, limitations at national borders have resulted in a lack of comparative research on species from different countries. To resolve the classification dispute, assess species diversity, and determine the distribution range of Micryletta, a series of specimens were collected from the Yunnan Province of China and Thailand during herpetological surveys from 2009 to 2020. Subsequent analyses based on morphological and molecular data revealed a distinct and previously unknown lineage from western Thailand, which we formally describe as a new species. Furthermore, our study confirms that M. ‘inornata’, previously known from Mengla, Yunnan, was actually M. menglienica, and further extends its distribution range to Thailand and Laos. In addition, our findings extend the latitudinal distribution of M. inornata and M. subaraji northward into southern Thailand. Notably, this study brings the total number of known species in the genus Micryletta from 13 to 14, with the count rising from three to six species in Thailand and from one to three in Laos. Our study further confirms that species diversity within the genus Micryletta is underestimated and emphasizes the important role that international collaborations play in taxonomy. Intensifying field surveys in other regions (e.g., Myanmar, Vietnam, and Guangxi of China) will be extremely necessary in the future to clarify any taxonomic questions and reevaluate the distribution range of these species.

Micryletta thongphaphumensis Cao, Suwannapoom, Kilunda, Wu & Che, sp. nov.

Diagnosis: Micryletta thongphaphumensis sp. nov. is assigned to the genus Micryletta based on the following combination of morphological traits: small body size; absence of vomerine teeth; tympanum small and externally visible; subarticular tubercles on fingers and toes prominent; three well-developed metacarpal tubercles; absence of webbing between fingers and toes (Dubois 1987; Fei et al. 2009). The new species differs from its congeners by a combination of the following characters: medium-sized within the genus (SVL 21.3–25.6 mm in males, n = 5; 24.4–29.7 mm in females, n = 4; Table 3); snout truncate in dorsal view; tympanum distinct; supratympanic fold absent; a black streak extending from tip of the snout to crotch; upper lip white; tibiotarsal articulation adpressed limb reaching level of tympanum; lack of webbing between fingers and toes; relative finger lengths: I < II < IV < III; relative toe lengths: I < II < V < III < IV; outer metatarsal tubercle absent; ventral skin of body and limbs smooth; brown marbling patterns on dorsal limbs; dorsal orange-brown with black spots (Fig. 4).

...

 

Etymology: The specific name is a Latinized toponymic adjective in neuter gender derived from ‘‘Thong Pha Phum’’ in reference to the type locality Thong Pha Phum District in Kanchanaburi Province, Thailand.

Suggested common name: We propose “Thong Pha Phum Paddy Frog” as the common English name.

[Ichthyology • 2024] Limnichthys koreanus • A New Species of creediid fish (Acropomatiformes: Creediidae) from Korea

Limnichthys koreanus 

Lee & Kim, 2024

DOI: 10.3897/zookeys.1214.128977

Abstract

Limnichthys koreanus sp. nov. is described on the basis of the holotype and 11 paratypes from subtidal waters of Seogwipo, Jeju Island, Korea. The new species had previously been regarded as the Northern Hemisphere population of the anti-equatorial L. fasciatus, but molecular analyses of mitochondrial COI and 16S genes recovers deep genetic divergences of 9.4% and 15.0% between the new species and topotypical specimens of L. fasciatus. Limnichthys koreanus sp. nov. is distinguished from all other species of Limnichthys based on the following combination of colouration and morphological characteristics: 38-40 vertebrae; 0–6 dorsal saddles joining mid-lateral stripe; small infraorbital sensory pores; a single median interorbital pore; and well-developed vomerine teeth. Summary characters for comparative congeneric species are provided.

We describe a new species in the Scinax granulatus group from the Atlantic Forest of northeastern Brazil and include the new species in an updated phylogenetic hypothesis for the group. The new species differs from all other species in the S. granulatus group by a combination of characters, such as a weakly bilobate vocal sac, moderately developed pre- and postaxial webbing of Toe IV, and advertisement call features. The newly described taxon is more similar with S. tropicalia, a species that is not closely related; both can be distinguished by the red-colored iris in the new species and differences in pulse rate of the call. The new species was recovered as the sister taxon of a clade including all other species of the S. granulatus group. However, the low support of some internal clades suggests that the knowledge about relationships in this group is still incomplete.

Etymology.— Rita Lee Jones de Carvalho, known as Rita Lee, was a Brazilian rock singer whose lyrics criticized the conservative, far-right, military dictatorship of the Brazilian government, which lasted from 1964 to 1985. She was a feminist activist, an ally of the LGBTQIAPN+ movement, and an environmentalist. Notably, Rita Lee is famous for her musical compositions and for her red-dyed hair, the latter trait considered unusual in her time. The reddish blotches in the iris of the new species are also an uncommon characteristic when compared to its congeners in the S. granulatus group. In this sense, we propose the new species epithet honoring the Queen of Brazilian rock music.

Abstract

The Philippine archipelago houses an incredibly diverse biota, among which are 122 species of pygmy grasshoppers (Orthoptera: Tetrigidae). Many of them belong to genera without proper taxonomic assignment and some genera, e.g., Bolivaritettix are so speciose and ill-defined that working with them is practically impossible. Here, we make a step toward the resolution of these problems by describing a new genus, Storozhenkotettix gen. nov. for Bolivaritettix amphinotoides, resulting in a new combination, S. amphinotoides comb. nov. This species does not seem to be closely related to the type species of Bolivaritettix, but rather to Trusmaditetrix, which is a member of the tribe Trusmaditetrigini. We provide new records of S. amphinotoides comb. nov., together with photographs of living specimens and habitat descriptions. The species was observed along the edges of montane forests and in the disturbed parts within forests. It seems to prefer partially shaded humid habitats.

Abstract 

Sophora phulangkaensis is illustrated and newly described here. The species shows similarities with its congener, S. exigua, by having an obovate terminal leaflet and up to 15 leaflets but differs in the floral parts. A morphological comparison between the two species is provided along with a discussion. The phylogenetic placement of the new species is presented and discussed based on molecular evidence by nuclear (ITS) and chloroplast markers (matK). The results suggest that the new species is nested into sect. Rubriflorae, which includes S. exigua and S. huamotensis. The circumscription of sect. Rubriflorae is expanded after being redefined by our findings. In addition, the updated key to species of the genus Sophora for the Flora of Thailand is given based on recent specimen observations. Additionally, lectotypes for S. exigua, S. tonkinensis, and S. violacea var. pilosa are designated.

Sophora phulangkaensis Mattapha, K.Khamm. & Suddee, sp. nov. 

 Closely related to S. exigua Craib, from which it differs by being a small shrub 0.5–2 m tall (vs undershrub up to 0.5 m tall in S. exigua), with sparse to dense hairs on midrib and margins of leaf blade (vs densely tomentose in S. exigua, particularly when young), presence of bracteoles (absent in S. exigua), the standard 15–16 mm long (18–20 mm long in S. exigua), filaments hairy at base with hairy anthers (glabrous in S. exigua), ovary densely strigose (tomentose in S. exigua) and longer pods (7–13 cm long vs 5–7 cm long in S. exigua). 

 Etymology. The specific epithet refers to the name of Phu Langka National Park, where the species was discovered.

Abstract

A new species, Chiloschista breviseta (Orchidaceae: Epidendroideae: Aeridinae) from Northern Thailand is described and illustrated, and notes on ecology and conservation status are provided. Chiloschista breviseta is morphologically similar to C. usneoides but differs in having much shorter seta on each side of the anther cap. Previous records of C. usneoides from Thailand refer to C. breviseta.

Diagnosis: Chiloschista breviseta is similar to C. usneoides in the largely white flower and the shorts accate lip with a rudimentary mid-lobe, but differs in having a short seta (<0.3 mm long) on each side of the anther cap (vs. a long, thread-like seta, >1.7 mm long) and in the Y-shaped callus apex (vs. T-shaped). It can be distinguished from C. viridiflava Seidenf. in having a glabrous abaxial surface of sepals and petal (vs. pubescent), margin of petals entire (vs. erose), and white sepals and petals, sometimes with a purplish pink median line abaxially (vs. pure pale green), and in having short setae (vs. setae > 1.9 mm long).

Etymology: From the Latin brevis, short, and seta, a bristle-like hair, referring to the short appendages on the anther cap, unlike the long wiry appendages seen in species like C. usneoides
