Abstract

Limestone karst habitats in tropical Asia support specialized and geographically restricted plant diversity, yet many areas remain incompletely explored. During botanical surveys of limestone habitats in northeastern Thailand, a distinctive, yellow-flowered population of Boesenbergia was discovered in Phu Pha Man District, Khon Kaen Province. Morphological observations were conducted on living plants in the natural population and spirit-preserved material, supplemented by comparisons with protologues, published descriptions, and herbarium material. Patterns of phenetic similarity among ten selected Boesenbergia taxa were evaluated using 32 morphological characters, Gower distance, UPGMA clustering, and principal coordinates analysis (PCoA). The population is described here as Boesenbergia calcicola Boonma, Saensouk & P.Saensouk, sp. nov. It is morphologically most comparable to B. petiolata but differs by its conspicuously exserted inflorescence, shorter bracts and flowers, distally puberulent floral tube, smaller puberulent lateral staminodes, and distinctive labellum color pattern. Phenetic analyses were used to summarize patterns of overall morphological similarity among the examined taxa. The species is currently known only from its limestone type locality at approximately 385 m a.s.l. and is provisionally assessed as Data Deficient (DD). This discovery further documents localized Boesenbergia diversity associated with limestone karst habitats in northeastern Thailand.

Boesenbergia calcicola Boonma, Saensouk & P.Saensouk

Diagnosis. Boesenbergia calcicola is morphologically similar to B. petiolata Sirirugsa in having a terminal inflorescence, lanceolate bracts, a broadly ovate to nearly orbicular labellum when flattened, and an anther crest absent, but differs by its inflorescence conspicuously exserted beyond the leafy shoot (vs. enclosed within or only shortly exserted from the upper leaf sheaths), shorter bracts, 1.5–2.5 cm long (vs. 3–4 cm long), shorter flowers, 2.0–2.5 cm long in lateral projection (vs. c. 4 cm long), a shorter calyx, 3.2–4.8 mm long (vs. c. 5 mm long), a floral tube 1.5–2.5 cm long and sparsely puberulent ...

Etymology: The specific epithet “calcicola” is derived from the Latin calx (genitive calcis), meaning “lime” or “limestone”, and -cola, meaning “dweller”, referring to the occurrence of the species on limestone substrates in Phu Pha Man District, Khon Kaen Province, northeastern Thailand.

[Ichthyology • 2026] Petulanos jasteri • A New Species of Petulanos (Characiformes: Anostomidae) from the Rio Araguari, Amapá State, Brazil

 

Petulanos jasteri

Birindelli, Lima & Gama, 2026

 DOI: doi.org/10.1643/i2025080

Abstract

The Neotropical family Anostomidae comprises over 150 valid species, though its true diversity remains underestimated. The genus Petulanos currently includes four species distributed across northern South America, all characterized by upturned mouths, compressed multicuspid dentition, and distinctive color patterns. In this study, we describe Petulanos jasteri, a new species apparently endemic to the rio Araguari, Amapá state, Brazil. Despite hosting extensive protected areas, Amapá remains poorly surveyed, and its ichthyofauna is still insufficiently documented. The new species is readily distinguished from congeners by its color pattern, consisting of three vertically elongated dark blotches on the posterior half of the trunk (without pale margins) combined with eight to ten dark vertical bars. It lacks the horizontal stripes that characterize P. brevior, as well as the rounded blotch above the pectoral fin present in P. intermedius, P. plicatus, and P. spiloclistron, and has 38 or 39 lateral-line scales (vs. 40 to 42 in P. spiloclistron). Osteological characters confirm its assignment to Petulanos, sharing synapomorphies such as four branchiostegal rays, bicuspid symphyseal premaxillary tooth, symplectic with a distinctive triangular ventral lamina, and open cranial fontanel. Petulanos jasteri, new species, is the first species of the genus reported from the rio Araguari. Its discovery emphasizes the underestimated diversity of the Anostomidae and highlights the need for further surveys and integrative studies in poorly explored basins of northern Brazil.

Petulanos jasteri, a new species 

Etymology.—The specific name jasteri honors Dr. Christoph Bernhard Jaster, formerly chief of the Tumucumaque National Park and the Amapá National Forest, for having made possible many field expeditions in these Conservation Units for the IEPA Ichthyology team, being a great supporter of basic science and biological surveys at Amapá State.

 Abstract 

Only three specimens of the Pink-bellied Imperial Pigeon Ducula poliocephala (G. R. Gray) are available from the isolated population on Tawi-Tawi Island, in the Sulu Archipelago, Philippines, and all have white (vs. brown) throats—a character shared with the closely related White-bellied Imperial Pigeon D. forsteni (Bonaparte). Two adults collected on Tawi-Tawi by the Menage Expedition, in 1891, are preserved in the National Museum of Natural History, Smithsonian Institution, Washington, DC. They bear archival labels with a nomen nudum (albigularis) indicating that the collectors initially considered them to be undescribed—because of the white throats—yet did not publish a description. A third white-throated specimen, collected in 1971 and preserved in the Delaware Museum of Nature & Science, Wilmington, confirms the morphological distinctiveness of the Tawi-Tawi population. Audio recordings from the 1990s further reveal that the Tawi-Tawi population is vocally distinct from D. poliocephala and D. forsteni. Based on its unique morphology and voice, I describe the ‘Tawi-Tawi Imperial Pigeon’ as a new species. It is endemic to the shrinking forests of Tawi-Tawi and faces an imminent risk of extinction.

Historic specimens of the ‘Tawi-Tawi Imperial Pigeon’Ducula tawitawi sp. nov. collected by Bourns and Worcester at Tataan (modern Tarawaken) during the Menage Expedition and held at the National Museum of Natural History, Smithsonian Institution, Washington, DC: (top left) USNM 314700, 21 October 1891; (bottom left) USNM 314701, 19 October 1891; the pale greenish-grey stains on the chins of these specimens were evidently caused by post-mortem fat migration (Matthew R. Halley; reproduced courtesy of the Bird Division, National Museum of Natural History, Smithsonian Institution, Washington, DC)

Ducula tawitawi sp. nov.

Tawi-Tawi Imperial Pigeon

Diagnosis.—D. tawitawi has the pink belly of D. poliocephala (unlike D. forsteni) but the white throat of D. forsteni (unlike D. poliocephala). Its courtship or advertising song has a unique acoustic structure consisting of a low-amplitude buzz or ‘rattle’ followed by more notes (5–8) compressed into a shorter time interval, resulting in a higher tempo, than D. poliocephala and D. forsteni.

Abstract

The taxonomic status of the medically important spider genus Loxosceles Heineken et Lowe, 1832 (Sicariidae) in Iran, Turkmenistan, and Afghanistan is revised. Two species are described as new to science: Loxosceles coheni sp. n. (♂♀, southwestern Iran) and Loxosceles turanensis sp. n. (♂♀, southern Turkmenistan and eastern Iran). Additionally, Loxosceles alicea Gertsch, 1967 syn. n. (♀, Peru) is synonymized with Loxosceles rufescens (Dufour, 1820). The local distribution of all treated species is mapped (including several new records), and reported cases of loxoscelism from this region are briefly reviewed.

Keywords: Central Asia, loxoscelism, Peru, recluse spiders, violin spiders

Taxonomy

Family Sicariidae Keyserling, 1880

Genus Loxosceles Heineken et Lowe, 1832

Type species. Scytodes rufescens Dufour, 1820, 

by subsequent designation of Bonnet (1957).

Loxosceles coheni sp. n.

Etymology. The new species is named in honor of Leonard Norman Cohen (21 September 1934 to 7 November 2016), a Canadian singer, songwriter, poet, novelist, and the most favorite artist of the first author, because his music kept him working during the long, cold, and dark winters of Finland.

Loxosceles turanensis sp. n.

  

Etymology. The specific epithet refers to Turan, a term of Iranian origin referring to a historical region in Central Asia and northeastern Iran, in which the currently known range of the new species is located.

Abstract

A new species of the genus Camellia L. (Theaceae) from Southern Vietnam is described and illustrated under the name Camellia proensis. Morphological differences between C. proensis and closely related species in the genus Camellia L. (sect. Piquetia) were identified. C. proensis is easily distinguishable from C. honbaensis, C. piquetiana and C. longii by the yellow flowers; from C. dalatensis by the glabrous twigs and leaves; from C. dongnaiensis by light yellow flowers; from C. sonthaiensis by mature fruit flat-globose, 4.0–5.5 cm tall and 8.5–10.0 cm wide. Ecological environment and distribution were also provided for this new species. The images and type specimens of this species were processed and stored in Vietnam (holotype, isotypes, DLU).

ABSTRACT

A deep bodied ray-finned fish is reported from Cisuralian lacustrine deposits of the Parnaíba Basin. Its ecological niche and systematic affinities are discussed, considering the paleogeographic distribution of selected Permo-Carboniferous deep bodied fishes from several separate sedimentary successions of western Gondwana. The occurrence of deep bodied fishes in the Parnaíba Basin mirrors the presence of a similarly shaped but less derived and distantly related taxon, Paranaichthys longianalis from the late Permian of the Paraná Basin of southern Brazil. The new taxon’s unique combination of characters includes an elongated pectoral fin; posteriorly inclined suspensorium; deep flank scales ornamented with fine vertical striae, tiny mandibular teeth and palatal crushing dental plates. It shares with Guildayichthys and Discoserra two preopercular bones, a supraorbital, and marginal teeth on the lower jaw. Phylogenetic analyses were performed based on two datasets. Dataset 1 included 53 characters coded for 26 deep bodied and fusiform fish fossils from Brazil, North America, China, South Africa, and Australia, with results indicating that is most closely related to the North American order Guildayichthyformes, known from marine rocks of Pennsylvanian age. Dataset 2 included 119 taxa coded for 293 characters. The two analyses place the new taxon as the sister group of a clade comprised of Blourugia and Paranaichthys. However, the results of the study of both datasets show a high degree of uncertainty about the interrelationships between the new taxon and other deep bodied Paleozoic fish species.

Abstract  

Curcuma roseobracteata P. Saensouk, Saensouk, Maknoi & Boonma sp. nov., a newly identified species within the Curcuma subgenus Curcuma of the Zingiberaceae family, has been found in the northern and southwestern floristic regions of Thailand, distributed in Mae Hong Son, Tak, and Kanchanaburi Provinces. This new species shares similarities with C. rubrobracteata Škorni?ková, M. Sabu & Prasanthkumar, and C. suraponii Boonma, but differentiated by its lemon yellow rhizome; leaves base broadly cuneate to rounded, or cordate, abaxial surface with scattered hairs; thyrse oblong ovoid; fertile bracts obovate, rose pink with a pale green base; coma bracts inconspicuous, with 1-4 in number; bracteoles apex rounded with short mucronate; filament c. 3 × 6 mm; anther c. 8.5 × 3.5 mm; epigynous glands c. 4.5 mm long; ovary 2.5-3 × 2.5 mm. The new taxon is formally described here, detailing its morphological characteristics, vernacular name, ecology, phenology, and distribution, which includes updates on the presence of C. suraponii, previously recorded only in Tak Province, but now also observed in Mae Hong Son Province. The study includes an IUCN conservation assessment based on recent collections and presents a revised taxonomic key to differentiate the new species from its relatives.

Abstract

Using an integrative dataset of both mitochondrial DNA and morphological data, we describe a new species of the genus Acanthosaura from the China-Myanmar border region in Menglian County, Pu’er, Yunnan Province, China. The new species, Acanthosaura aurantiogularis sp. nov., is sister to A. tongbiguanensis, and it can be readily diagnosed from all recognized congeners by its bright orange gular coloration in the male, flesh colored oral cavity, moderate post-orbital spines and occipital spines, five or six well-developed nuchal crest scales, and a distinct dorsal coloration. We recommend further comprehensive phylogenetic studies of the genus and highlighted the understudied agamid diversity in northeastern Myanmar.

Acanthosaura aurantiogularis Wang, Lu & Che, sp. nov.

Diagnosis. Acanthosaura aurantiogularis sp. nov. can be diagnosed from congeners by a combination of the following morphological characters: (1) tail short, TAL 167% SVL in female; (2) length of post-orbital and occipital spines moderate, LOPS 11.0–15.1% HL, LLOC 9.5–15.9% HL; (3) nuchal crest erected, 5 or 6, discontinuous from dorsal crests, TNCL 13.8–18.7% HL; (4) diastema short, composed of 6–8 small scales; (5) dorsal crest erected, anterior most one shorter than nuchal, decreasing in length posteriorly; (6) enlarged middorsal crest scales 41; (7) gular pouch moderately developed, transverse gular fold ...

Etymology. The specific epithet aurantiogularis is a compound Neo-Latin adjective derived from the Latin aurantius, meaning “orange-colored,” and gularis, meaning “the throat”. This nomenclature is a direct descriptor of the lizard’s most striking and diagnostic morphological feature: the vibrant, unmarked orange-yellow gular pouch in males. The suggested Chinese common name is “橙喉棘蜥” (Pinyin: Chéng Hóu Jí Xī), and the suggested English common name is Orange-throated Pricklenape.

Abstract

The genus Oreolalax of the family Megophryidae currently comprises 22 recorded species, the majority of which are endemic to China. During field work in Liziping National Natural Reserve, Shimian County, Sichuan Province, China, we discovered several Oreolalax toads with morphological characteristics different from other Oreolalax species. Based on the analyses of morphological, bioacoustic and molecular data, this newly identified population forms an independent clade nested with Oreolalax lichuanensis, Oreolalax schmidti and Oreolalax pingii, which we describe as a new species. The new species, Oreolalax lizipingensis sp. nov., can be distinguished from other congeneric species by the combination of the following characters: (1) relatively small body size in Oreolalax, SVL of males 37.6–43.3 mm and females 44.2–52.7 mm; (2) toes with rudimentary webbing; (3) interorbital region with dark triangular spot; (4) the female’s belly, flanks and lower surface of limbs evenly dotted with white spots, absent or inconspicuous in males; (5) dorsum with dark brown and nearly round warts; (6) male with spiny warts along edge of jaw, ventral thighs and abdomen near vent; and (7) breeding season occurring from July to August. Oreolalax lizipingensis sp. nov. is currently known only from high-elevation streams at 2400–3100 m a.s.l. within the Menghuo Castle where it occurs in sympatry with Oreolalax liangbeiensis.

Key Words: New species, Oreolalax lizipingensis sp. nov., taxonomy

Oreolalax lizipingensis sp. nov.

Diagnosis.

Oreolalax lizipingensis sp. nov. assigned to the genus Oreolalax based on its phylogenetic position and the following characters: pupil vertical; vocal sac absent; dorsal surface exhibiting dark-colored and nearly round tubercles; males possessing a pair of chest glands densely covered with black spines (Fei et al. 2009).

The new species differs from its congeners by a combination of the following morphological characters: (1) the body size relatively small, SVL of adult males 40.2 mm (37.6–43.3 mm, n = 5); adult females 47.7 mm (44.2–52.7 mm, n = 3); (2) head length slightly longer than head width; (3) tongue deeply notched posteriorly; (4) supratympanic fold narrow and elongated; (5) tympanum hidden; (6) hand without subarticular and ...

Etymology. The specific epithet “liziping” of the new species refers to the type locality of the species, Liziping National Nature Reserve, Sichuan Province, China. 

We suggest the common name as “Liziping toothed toad”, and the Chinese name as “Li Zi Ping Chi Chan (栗子坪齿蟾)”.

Abstract

A new species of phytotelma-breeding dragonfly, Lyriothemis abrahami sp. nov., is described from the Western Ghats of Peninsular India. The new taxon was previously misidentified as L. flava Oguma, 1915 (= L. tricolor Ris, 1916). In contrast to L. flava, the new species is sexually dimorphic, with males easily identified based on the characteristic shape of the hamules. Females are identified by their jet black and yellow colour with triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. Photographs of mature adults, tenerals, hamules, illustrations of vesica seminalis, vulvar lamina, and a key to Lyriothemis of the Indian subcontinent are provided.

Lyriothemis abrahami Sadasivan, Jose, Nair & Palot, sp. nov.

Diagnosis. Males of Lyriothemis abrahami sp. nov. are identified by the combination of the following characters: two short oval paradorsal streaks on the mesepisternum not extending halfway up the thorax towards the alar sinus; anterolateral yellow thoracic band as broad as or narrower than the black area just posterior to it; in anteroventral view hamule trapezoid, higher than wide; hamular inferolateral angle right-angled and well-defined, medial border with a distinct insinuation at the junction of its inferior and middle third, inferior border straight. The elongated shape of the hamule is a distinct characteristic of the new taxon. Sexual dimorphism is strongly exhibited in L. abrahami sp. nov., with the females identified by their jet-black and yellow colour with characteristic triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. The new species is endemic to the Western Ghats of Peninsular India, south of Coorg, and its distribution does not overlap with the range of L. flava, as far as it is known.

Etymology. The species is named after Dr. Abraham Samuel, a pioneer of odonatology from Kerala, for his contributions to the field and his constant encouragement to the authors. The specific epithet is a noun in the genitive case.

Abstract

Mainland Southeast Asia, also known as Indochina, is recognized as a global biodiversity hotspot for freshwater mussels, hosting a significant number of species and exhibiting high levels of endemism. Recently, the monotypic genus Songkhlanaia was described from the Songkhla Lake Basin in southern Thailand. In this study, two additional lineages are revealed, S. moreleti comb. nov. and S. songkhramensis sp. nov., from the Mekong Basin through an integrative taxonomic approach combining morphological characters and molecular phylogenetic analyses. The multi-locus phylogenetic inference supported the monophyly of the genus and further elucidated the sister relationship between S. moreleti and the new species, and with S. tamodienica positioned as a basal lineage. Pairwise uncorrected COI p-distances among these three species also supported the species validity and ranged from 4.2% to 8.24%. Notably, S. songkhramensis sp. nov. and S. moreleti exhibit similarities in shell morphology; however, the new species can be differentiated by more robust pseudocardinal teeth. Both species are distinguishable from S. tamodienica by their approximately twice larger size, more inflated shells, and more prominent, roughened, irregular growth lines on the shell surface. Furthermore, based on the current data, these three species are recognized as endemic and are restricted to disjunct biogeographic areas in Indochina: S. tamodienica in the Songkhla Lake Basin in southern Thailand, S. moreleti in the Tonle Sap and Lower Mekong basins, and S. songkhramensis sp. nov. in the Songkhram Basin and its nearby tributaries of the Middle Mekong Basin.
