 Abstract
A molecular phylogenetic study was conducted on genus Grandinenia, based on COI and 16S sequences. A total of eight out of 26 species in the genus, as well as three unidentified species were sequenced. Phylogenetic results supported the monophyly of Grandinenia and the validity of all sampled species and subspecies. A new species, Grandinenia jiangjilini Chen, Lin, Wu & Ouyang, sp. nov., from Guangxi, southern China is identified and described, based on morphological comparison and molecular phylogeny. The discovery indicates that the inflated-fusiform shell is not isolated in genus Grandinenia and the species diversity of the genus still remains to be explored.

[Herpetology • 2024] Xenophrys apatani • On A New Species of Xenophrys (Anura: Megophryidae) from Tale Wildlife Sanctuary, Arunachal Pradesh, India with Comments on the earlier erroneous report as X. maosonensis (Bourret, 1937)


 Xenophrys apatani 
Saikia, Sinha, Shabnam, et al., 2024. 

The Maoson horned frog, Xenophrys maosonensis (Bourret, 1937) was originally described as Megophrys longipes maosonensis from Vietnam having distribution in China. Saikia et al. (2019) reported its occurrence from Arunachal Pradesh as a first country record for India with the inclusion of genetic data and morphological descriptions. They arrived at the species-specific identity based on the NCBI BLAST search of molecular sequence data of 12S rRNA and 16S rRNA which showed homology search of 95.4 – 97.5% similarity with X. maosonensis and ‘selective phylogeny’. However, the earlier genetic difference of ca. 4.6% – 2.5 % (12S and 16S, respectively) with X. maosonensis sensu stricto vis-à-vis the specimen from Arunachal Pradesh, India; coupled with the huge biogeographic barrier of ca. 1600 kms. aerial distance between the two localities, makes it very unlikely of such a disjunct distribution of the species. This warranted a re-evaluation on the specific identity of the specimen from India. Now, based on comprehensive phylogeny (including 142 sequences) of the subfamily Megophryinae, the earlier erroneously reported X. maosonensis from India is described here as a species new to science as Xenophrys apatani sp. nov. based on integrative taxonomic approach. Interestingly now, the proposed new species is exhibiting 4.4% to 5.5% genetic distance with the X. maosonensis sensu stricto from Vietnam. Additionally, morphological character differences between the congeneric species reported from India and of X. maosonensis sensu stricto with the proposed new species is provided. A discussion on the biogeographic distribution of Xenophrys in India is made.

[Herpetology • 2024] Uropeltis caudomaculata • A New Species of Uropeltis Cuvier, 1829 (Serpentes: Uropeltidae) from the eastern escarpment of the southern Western Ghats, India


Uropeltis caudomaculata
Gower, Das, Deepak, Gerard & Narayanan, 2024

 
Abstract
A new species of the uropeltid (‘shieldtail’) snake genus Uropeltis is described based on eight specimens from the southern part of peninsular India’s Western Ghats. Uropeltis caudomaculata sp. nov. is phenotypically and genetically most similar to U. pulneyensis (Beddome, 1863), but differs primarily in having more ventral scales and in being restricted to the eastern escarpment of the Western Ghats between Meghamalai and approximately 15 km East of Munnar rather than in the Palani Hills, as well as differing in DNA nucleotide sequences. From verified records, we consider U. pulneyensis to be known thus far only from the Palani Hills, and we designate a lectotype for the species. Reconsideration of the holotype of Silybura guentheri Beddome, 1878 from Meghamalai leads us to conclude that it should be removed from the subjective junior synonymy of U. pulneyensis and be considered a distinct though very poorly known species, Uropeltis guentheri comb. nov.

in Debta, Shenoy, Akhil et Nampy. 2024.   

Abstract
Aeschynanthus maoi, a new species of Gesneriaceae from Lower Dibang Valley of Arunachal Pradesh, India, is described and illustrated. It is morphologically similar to A. wardii and A. bracteatus, but differs from the former by its small (3–5 mm long) boat-like bracts, narrowly ovate or triangular calyx lobes, 1–8 flowered inflorescences, and turbinate staminodes. It differs from the latter by caducous green bracts, short peduncles (0.2–0.8 cm long), and narrowly ovate or triangular green calyx lobes. A detailed description of the new species with color photographs and a comparison to similar species are provided. The new species is evaluated for risk of extinction and provisionally assessed as Critically Endangered (CR) according to IUCN Red List Categories and Criteria.

[Ichthyology • 2024] Microdous hanlini • A New Species of the fine-toothed Sleepers (Gobiiformes: Odontobutidae) from Guangxi, China

 
Microdous hanlini Wang, He & Li,

in Wang, Wei, He et Li, 2024. 

Abstract
Microdous (Gobiiformes: Odontobutidae) is a genus of freshwater sleepers distributed in southern China and Vietnam. There are two described species in this genus, M. chalmersi widely distributed in Hainan Island and Guangxi province of China and M. amblyrhynchos with a very restricted distribution range in Baise, Guangxi. It has been reported that M. chalmersi of Guangxi might be a cryptic species, which is different from M. chalmersi of Hainan. Here, we describe the cryptic species from Guangxi as a new species, Microdous hanlini, and compare it with the other species of Microdous. Microdous hanlini can be distinguished from M. chalmersi by its wider head (head width/head length = 0.51–0.58 vs. 0.48–0.53 in M. chalmersi) and wider interorbital width (interorbital width/head length = 0.15–0.19 vs. 0.09–0.13 in M. chalmersi). Microdous hanlini can be distinguished from M. amblyrhynchos by its longer snout, (snout length/head length = 0.29–0.35 vs. 0.26–0.28 in M. amblyrhynchos); slenderer head (head width/head length = 0.51–0.58 vs. 0.61–0.65); and protruding eyes (vs. not protruding). Phylogenetics analyses based on partial sequence of cytochrome c oxidase subunit I (COI) gene (~1500 bp) showed that M. hanlini, M. chalmersi and M. amblyrhynchos formed reciprocal monophyletic clades and M. hanlini is more closely related to M. amblyrhynchos than to M. chalmersi. Genetic distance between the three species is greater than the interspecific distance between some species of Odontobutis.

Microdous hanlini Wang, He & Li, sp. nov.

Diagnosis. The species M. hanlini can be distinguished from M. chalmersi (Nichols & Pope, 1927) by the following characteristics: wider head, head width/head length = 0.51–0.58 (vs. slender head, head width/ head length = 0.48–0.53); wider interorbital width, interorbital width (bone)/head length = 0.15–0.19 (vs. slender head and narrow interorbital width, interorbital width (bone)/head length = 0.09–0.13). The species can be distinguished from M. amblyrhynchos by the following characteristics: snout pointed, snout length/head length ratio 0.29–0.35 (vs. blunt snout, snout length/head length ratio 0.26–0.28); slenderer head, head width/ head length = 0.51–0.58, (vs. head width/head length =0.61–0.65); eye large and protruding outward (vs. eye not protruding) (Fig. 3, Table 1). The species M. hanlini can be distinguished from Sineleotris saccharae by absence of dark band under eye. The species M. hanlini can be distinguished from Sineleotris namxamensis by the following characteristics: lateral scale rows 40-43 (vs. 36-39); transverse scale rows 14-16 (vs. 12-14). These distinguishing features showed no difference between male and female individuals of M. hanlini (Table 2.)
...

Etymology. The species name is named after Prof. Hanlin Wu in honor of his significant contributions to the study of the gobiiform fishes of China.

[Ichthyology • 2024] Poropuntius anlaoensis • Taxonomic Revision of the Southeast Asian Brook Barb Genus Poropuntius Smith, 1931 (Cypriniformes: Cyprinidae) with Description of A New Species from Vietnam

 

Poropuntius anlaoensis Hoàng, Phạm & Trần,

in Hoang, Pham, Tran, Durand, Wu, Pfeiffer, Chen et Page, 2024. 

Abstract
Molecular data from samples encompassing 22 nominal species of Poropuntius indicate that the species-level diversity in the genus has been vastly overestimated, likely due to inadequate taxon and geographic sampling and reliance on morphological characters that vary intra-specifically. The latter includes discrete mouth morphologies related to alternate feeding strategies (ecomorphs) within populations. One new species is described, Poropuntius anlaoensis Hoàng, Phạm & Trần, sp. nov., and 17 synonyms of six valid species names of Poropuntius, P. krempfi, P. alloiopleurus, P. huangchuchieni, P. laoensis, P. kontumensis, and P. deauratus, are recognised. Additional taxonomic changes in this widespread and generally poorly known genus are likely as more molecular and morphological data become available.

 Artwork by Fatima Bracamontes 

Abstract
Background: The genus Pinguicula harbors 110 species, of which 53 are distributed in Mexico. The formation of the Mexican mountains has favored the Pinguicula diversification. Pinguicula specimens collected in the State of México, along the Trans-Mexican Volcanic Belt (TMVB) do not correspond with any known species.

Questions: Do the collected specimens belong to a new species? What is its conservation status? How many Pinguicula species are there along the TMVB and how do they differentiate? How is the Pinguicula species richness distributed?

Studied species: Pinguicula.

Study site and dates: TMVB, 2005-2023.

Methods: Based on herbarium specimens and recently collected material, a morphological analysis and description were made. Conservation status was assessed following IUCN Red List Categories and Criteria. Herbarium specimens and digital records of Pinguicula from the TMVB were examined to generate a list and key. We analyzed the richness distribution of Pinguicula by states, vegetation types, elevation ranges, and grid cells.

Results: Pinguicula tlahuica is proposed as a new species. It is distinguished by the linear-spatulate summer leaves. The new species falls into the Endangered (EN) category. Along the TMVB, 16 species of Pinguicula are distributed. The State of México, Hidalgo and Michoacán, and the pine-oak forest were the richest. Pinguicula appeared between 759-3,427 m asl. The grid cell analyses revealed different areas with high richness.

Conclusions: Along the TMVB, the Pinguicula species richness centered on the Eastern and Western sectors. Pinguicula crassifolia, P. michoacana, P. tlahuica, and P. zamudioana are endemic to the TMVB.

Polylepis rocio-rojasii
  
in Gamarra et Valdivia, 2024.
 
Abstract
A new species of Polylepis (Rosaceae) from the Humid Puna of the Bosque de Proteccion Pui-Pui in Junin, Peru, is described and illustrated. The new species was found at 3800 m elevation, in small patches or forest relicts of the natural protected area, growing in open areas highly exposed to wind and abundant fog, along with other shrubby species, mainly Chusquea tessellata (Poaceae). It is very similar to Polylepis canoi but differs by trifoliolate leaves with larger leaflets, lanuginose abaxially, and rounded to ovoid achenes, smaller than those of P. canoi. We also present details on its geographic distribution, ecological notes, and an assessment of the conservation status of the new species.

Abstract
Garter snakes in the genus Thamnophis from Mexico have a long and convoluted taxonomic history. From 2015 to 2022, we conducted a comprehensive sampling of Mexican Thamnophis species, aiming to link molecular phylogenies with the recognized species related to T. scalaris in the highlands of Mexico. Here, we present an analysis of mitochondrial DNA to resolve the status of two enigmatic highland Thamnophis populations. Our research resulted in the identification and morphological characterization of a previously undescribed Thamnophis species from the state of Jalisco in western Mexico. We also clarify the identity and relationships of several previously enigmatic populations of Thamnophis. This work presents new data for Thamnophis phylogenetics from the Mexican highlands and offers a framework for future conservation efforts.

[Botany • 2024] Orophea chalermprakiat (Annonaceae: Malmeoideae) • A New Species from Satun UNESCO Global Geopark, southern Thailand


 Orophea chalermprakiat Damth., Chanthamrong & Chaowasku, 

in Damthongdee, Chanthamrong, Promsiri, Tongsang, Jaisamut, Wiya, Sinbumroong et Chaowasku, 2024.  
“เฉลิมพระเกียรติ” DOI: 10.11646/phytotaxa.658.3.8

Orophea Blume (1825: 18) (Annonaceae) consists of about 62 species distributed collectively from the Indian subcontinent through mainland Southeast Asia and southern China to the Southeast Asian islands (not further to the east than the Moluccas; Kessler 1988). It is a member of Miliuseae, the largest tribe of Malmeoideae (Chatrou et al. 2012). The genus is primarily characterised by the presence of (1) dissimilar petal whorls, the inner petals being usually longer, clawed toward the base and usually connivent at anthesis, (2) reduced number of stamens and carpels per flower and (3) loosely arranged stamens with a minute connective prolongation not covering the thecae (Damthongdee et al. 2021). Furthermore, most species of Orophea possess varying shapes of glands inside the inner petals (Kessler 1988, Leonardía & Kessler 2001). The genus has been subdivided into two subgenera: Orophea and Sphaerocarpon Kessler (1988: 13). Members of O. subg. Orophea possess generally percurrent tertiary leaf venation and ellipsoid-cylindrical to cylindrical monocarps (± moniliform when multi-seeded), whereas members of O. subg. Sphaerocarpon exhibit generally reticulate tertiary leaf venation and globose (rarely shortly oblongoid) monocarps (Damthongdee et al. 2021). In Thailand, there are eight species, including the recently described O. sichaikhanii Damthongdee, Aongyong & Chaowasku (2021: 308). In this study, we describe a new species of O. subg. Sphaerocarpon from Satun UNESCO Global Geopark, Satun Province, southern Thailand. The indumentum terminology of Hewson (1988) was used. Floral organs were studied and measured from material in spirit.

Orophea chalermprakiat Damth., Chanthamrong & Chaowasku, sp. nov. 

 Type:—THAILAND. Satun Prov.: La-ngu Distr., (holotype: CMUB003998801; isotypes: BK, CMUB, PBM, QBG). 

The new species is morphologically most like O. sichaikhanii but differs from it by having pilose-villous young twigs and petioles, shorter petioles, rounded to subcordate (rarely obtuse) leaf bases, shorter flowering pedicels, longer inner petal claws, lower number of carpels per flower and longer monocarp stipes (Table 1).
...

Distribution:—Endemic to Satun Province, southern Thailand. 

Habitat and phenology:—Evergreen forests in a limestone sink, ca. 25 m. Flowering and fruiting material collected in November.

Etymology:—Derived from a Thai royal term meaning “honour”, the specific epithet honours King Rama X of Thailand [Phra Wachiraklao Chao Yu Hua] on the auspicious occasion of his 72nd (6th cycle) birthday anniversary (28 July 2024).

[Botany • 2024] Ruellia kalungae (Acanthaceae: Ruellieae) • A New Species from Goiás state, Brazil


Ruellia kalungae  G.V.R.Mendonça & M.J.Silva, 

in Mendonça et da Silva, 2024.
 
Abstract
Taxonomic studies about Ruellia from Goiás state, Brazil, ongoing, revealed a new species, R. kalungae, that it is here described and illustrated, and systematically positioned. The novel species is similar to Ruellia nitens in the subshubby erect habit, leaves light green and corolla infundibuliform. However, it differs from the latter by several characters related specially to the shapes and indument of the leaves, bracts and capsules, inflorescence type, aspect and size of the calyx lacinia, presence de bracteoles, and number and shape of the seeds.

[Botany • 2024] Eugenia guapiassuana (Myrtaceae) • A remarkable New tree Species from the Brazilian Atlantic Forest


 Eugenia guapiassuana  T.Fern., M.T.C.Lacerda & J.M.A.Braga, 

 in Fernandes, Prieto, Lacerda, Bünger et Braga, 2024. 

Summary
This study proposes a new species of Eugenia sect. Phyllocalyx from Atlantic Forest remnants in the Brazilian state of Rio de Janeiro. The new taxon, Eugenia guapiassuana, is proposed based on literature survey, examination of herbarium material and field work. We herein provide a morphological description, including comments on fruit taste, along with information on distribution, habitat, phenology, vernacular name, taxonomy and conservation status. Figures showing fresh and dry material and a map of the occurrence records are also presented. Eugenia guapiassuana is morphologically similar to E. involucrata and E. superba, and these species are contrasted in the discussion. Following an assessment, the conservation status of Eugenia guapiassuana is provisionally determined as Critically Endangered [CR B2ab(iii)].

Key Words: Cereja-de-guapiaçu, Eugenia sect. Phyllocalyx, fruit tree, Reserva Ecológica de Guapiaçu, threatened species

Morphology of Eugenia guapiassuana.
A leaf adaxial surfaces with puberulent indument; B leaf abaxial surface; C leafy shoots, adaxially cinereous, sericeous, abaxially glabrous and vinaceous; D inflorescences developing along with leafy shoots; E flower bud at early stages of development; F pre-anthetic flower; G flowers at anthesis; H flower from below, showing the cordiform bracteoles; J post-anthetic flower, after stamens fall; K detail of the thick, verrucose pedicel in fruit, swollen at base and apex; L mature fruit with persistent trichomes concentrated on the transition with the calyx (arrowed); M mature fruits.

ETYMOLOGY. The epithet is a tribute to Reserva Ecológica de Guapiaçu (REGUA), an outstandingly important area for the conservation of Atlantic Forest biodiversity, close to which the new species was found. Guapiaçu (latinised Guapiassu) is treated as an institutional name and adjectivised as guapiassuana. The Tupi indigenous word Guapiaçu (= large headwaters) is the name of the main river crossing the Reserve.

[Botany • 2023] Catasetum krahlii (Orchidaceae: Catasetinae) • A New and threatened Species from the Brazilian Amazon


Catasetum krahlii D.R.P.Krahl, Cantuária, J.B.F.Silva & Chiron, 

 in Krahl, Oliveira, Silva, Chiron et Cantuária, 2023. 
 
Abstract
In the present study we propose a new Catasetum taxon belonging to the group of species with symmetrical and converging antennae. It was found in a vegetation of “terra firme” and “campinarana” in the central Brazilian Amazon. A detailed description of the taxon is given as well as a photograph plate and comments relating to distribution, habitat, phenology and conservation status. It is compared to C. rivularium and C. barbatum which are sympatric species and somewhat similar to the new taxon. Furthermore, we present a key to Catasetum species with symmetrical and convergent antennae occurring in the Brazilian Amazon.
