[Botany • 2022] Coelogyne sondangii (Orchidaceae: Epidendroideae: Coelogyninae) • A New Species from Vietnam

 Coelogyne sondangii Vuong, Aver. & V.H.Bui, 

in Vo, Averyanov, Maisak, Bui, ... et Truong, 2022. 

Coelogyne sondangii is described as a species new for science. It allies to the group of former Panisea species with white flowers, namely C. albiflora, C. demissa, C. yunnanensis, C. panchaseensis, and C. sagittata, but differs from them in big flowers, narrowly spatulate lip with erose margin of lobes and irregularly denticulate column wings. In addition, C. moi is firstly recorded and documented for the flora of Vietnam, as well as new nomenclatural combination, Coelogyne sagittata (T.C.Hsu, H.C.Hung & Luu) Vuong & Aver., is proposed.

[Botany • 2022] Sobralia rinconiana (Orchidaceae: Sobralieae) • A New Species from Panama

Sobralia rinconiana  Serracín, Samudio & Bogarín, 
in Serracín, Samudio & Bogarín, 2022. 
In Panama, the Orchidaceae comprise 187 genera, of which one of the most conspicuous is Sobralia. The flowers of Sobralia are mostly ephemeral but colorful, often fragrant, and of variable sizes. Despite being a prominent group, its taxonomy is still underdeveloped in most neotropical countries. To continue with taxonomic studies in the Orchidaceae of Panama, we investigated a species of Sobralia, which differs from any recorded species of the genus. We documented the species with digital images and compared it with morphologically similar taxa. This paper describes and illustrates a new Sobralia from the Bosque Protector Palo Seco in the Fortuna area, Panama. Sobralia rinconiana differs from all other species recorded in Panama by the combination of a large plant size that reaches up to 120 cm high and the larger and broader, elliptical-lanceolate leaves (30–35 × 14–16 cm). Sobralia rinconiana is most similar to S. carazoi but differs in the spreading flowers with reflexed petals and the infundibuliform, cream-yellow lip, the wider, longer sepals and petals, and the longer, suberect column. The accurate estimate of the number of Sobralia species in Panama is still uncertain. Its diversity may increase as new areas are explored or species complexes are resolved.

[Invertebrate • 2021] Inermonephtys turcica & Nephtys sinopensis • Nephtyidae (Annelida: Polychaeta) from the Sea of Marmara and Black Sea, with Descriptions of Two New Species

 Inermonephtys turcica
Kuş, Kurt & Çinar, 2021

The present paper deals with the diversity of nephtyid polychaetes (Nephtyidae) from the Sea of Marmara and the Black Sea. Three species belonging to two genera (Micronephthys and Nephtys) were found in the Black Sea (coast of Turkey) and six species belonging to three genera (Inermonephtys, Micronephthys and Nephtys) were found in the Sea of Marmara. The material includes two species new to science, Inermonephtys turcica n. sp. and Nephtys sinopensis n. sp., and a species record (Nephtys kersivalensis McIntosh, 1908) new to the Sea of Marmara’s marine fauna. Nephtys sinopensis n. sp. is mainly characterized by having 1–4 geniculate chaetae in the postacicular position of the parapodia; digitiform antennae, palps, and ventral cirri at chaetiger 1 with swollen tips; small and cirriform branchiae present from chaetiger 4 to the end of the body; poorly developed parapodial prechaetal lamellae in median and posterior chaetigers and long ventral cirri along the body. Inermonephtys turcica n. sp. is mainly characterized by having cushion-like palps with digitiform tips; well developed neuropodial postchaetal lamellae; barred chaetae in preacicular position of the anterior and median parapodia; and branchiae first appearing between chaetiger 3 and 13 (depending on body size).

[Herpetology • 2022] Amolops shihaitaoi • A Cryptic Species of the Amolops ricketti Species Group (Anura: Ranidae) from China–Vietnam Border Regions

 Amolops shihaitaoi
Wang, Li, Du, Hou & Yu, 2022

Hekou torrent frog | 河口湍蛙  ||  DOI: 10.3897/zookeys.1112.82551

It was supposed that the current records of Amolops ricketti might be a species complex composed of multiple species. In this study, on the basis of wide sampling, we found that the records of A. ricketti from Yunnan, China, and northern Vietnam actually represent a cryptic species based on morphological and molecular evidence. Amolops shihaitaoi sp. nov. can be distinguished from other members of the A. ricketti species group by its moderate body size (SVL 35.5‒37.3 mm in males and 39.2‒45.7 mm in females); white spines on the temporal region, loreal region, snout, and lips in breeding males but absent in females; overlapping heels; tibiotarsal articulation reaching tip of snout; indistinct longitudinal glandular folds on the skin of the shoulders; presence of supernumerary tubercles below the base of fingers II‒IV, distinct pineal body; presence of vomerine teeth; and absence of vocal sacs. Phylogenetic analysis supports that the new species is sister to Amolops yatseni and the populations from Jingxi, Guangxi and Lào Cai, Vietnam previously reported as A. yatesni also belong to it. Additionally, our results indicate that more cryptic species may exist within the A. ricketti species group, implying that more studies are needed to achieve a complete understanding of the species diversity of this group.

Amolops yatseni in Wu et al. (2020); 
Amolops tonkinensis in Poyarkov et al. (2021).

The new species is assigned to genus Amolops and further to the A. ricketti group morphologically based on the absence of dorsolateral folds, presence of circummarginal groove on disc of the first finger, disc of first finger distinctly smaller than that of second finger, absence of tarsal fold and tarsal glands, and presence of nuptial pads with conical nuptial spines on the first finger in breeding male.

Amolops shihaitaoi sp. nov. can be distinguished from other members of A. ricketti group by having a combination of the following characters: body size moderate (SVL 35.5‒37.3 mm in males and 39.2‒45.7 mm in females); white spines on temporal region, loreal region, snout, and lips present in breeding males but absent in females (Fig. 5); presence of small, dense, translucent or white spines on the dorsal skin of the body, dorsal and dorsolateral skin of limbs; heels overlapping; tibiotarsal articulation reaching tip of snout; longitudinal glandular folds on the skin of shoulders indistinct; presence of supernumerary tubercles below the base of fingers II‒IV, pineal body distinct; presence of vomerine teeth; and absence of vocal sacs.

Etymology: Specific epithet shihaitaoi is named after Prof. Hai-Tao Shi from Hainan Normal University for his outstanding contribution to the herpetology of China.

[Entomology • 2022] Ctenostegus hansoni • A New Species of Spider Wasp (Hymenoptera: Pompilidae) endemic to Lord Howe Island, Australia


Ctenostegus hansoni
Rodriguez & Evangelista, 2022

Lord Howe Island is a UNESCO World Heritage Site with a highly endemic biota and a history of recent species extinction. During the 2017 and 2018 Australian Geographic Society expeditions to Lord Howe Island, spider wasps in the genus Ctenostegus Haupt, 1930 were collected from various sites. A new species – C. hansoni sp. nov. – is described based on this material. The external morphology and male genitalic features are illustrated for all constituents of the C. immitis species-group, for which an identification key is provided. New distribution data for the Hymenoptera of Lord Howe Island include an additional genus of Pompilidae (Fabriogenia sp.) and the first record for the family Mutillidae (Ephutomorpha sp.). Ctenostegus hansoni sp. nov. is one of the few spider wasps restricted to an oceanic island and constitutes an intriguing new record of long-distance dispersal from mainland Australia followed by speciation.

in Vogel, Mallik, ... et Ganesh, 2022. Ashok Kumar Mallik
We revisit the identities of ‘Trimeresurus albolabris’ records from India and Nepal, based on a re-examination of historically mentioned specimens. Based on morphological congruence, we identify an old specimen originally labeled as T. albolabris from ‘Nagpur, Central Province’ as Trimeresurus salazar. We also provide new records of T. salazar based on molecular data from newly collected specimens in Central India. As the range of T. salazar is now known to approach that of its sister species Trimeresurus septentrionalis, we also redescribe T. septentrionalis based on the holotype and referred material. Finally, we examined two historical specimens from “Madras” collected during the Novara Expedition, which we identify as T. davidi, leading to a reassessment of their origin. Consequently, we remove T. albolabris from the list of Indian snake fauna.

[Botany • 2022] Euphorbia marciae (Euphorbiaceae) • A New Species from the Balsas Depression of Mexico

Euphorbia marciae V.W. Steinm., 

in Steinmann, 2022. 

Euphorbia marciae, a new species from the lowlands of the Balsas Depression in southwestern Mexico, is described and illustrated. The species was first collected by the renowned botanist George B. Hinton during his explorations of the area in the 1930s. It is known from only five collections made in northwestern Guerrero and the extreme southwestern portion of the state of México, at elevations from 250 to 610 m. Vegetation of the area is tropical deciduous forest. Euphorbia marciae belongs to Euphorbia subg. Chamaesyce sect. Anisophyllum and resembles E. apatzingana, E. hyssopifolia, and E. nutans. However, it differs from these species in having smooth seeds. The seeds are nearly identical to those of E. pionosperma, an endemic species occurring in the Sierra Madre Occidental of eastern Sonora and western Chihuahua. However, the leaves of E. pionosperma are more conspicuously serrate and have larger stipules. In addition, Euphorbia pionosperma has smaller involucres and involucral appendages. Following IUCN Redlist criteria, E. marciae should be treated as Data Deficient (DD) until the species can be relocated and its populations field evaluated.

Euphorbia marciae V.W. Steinm.,

Etymology Euphorbia marciae is named after my mother, Marcia Marie Steinmann, née Bradley (1938–2018), who not only gave me my life, but always offered unconditional support and encouragement, especially with regard to my interest in biology.

[Herpetology • 2022] Hynobius oni • A New Species of Lotic Breeding Salamander (Caudata: Hynobiidae) from Shikoku, Japan

Hynobius oni 
Kanamori​, Nishikawa, Matsui & Tanabe, 2022

Background: Hynobius hirosei is a lotic-breeding salamander endemic to Shikoku Island in western Japan. Significant allozymic and morphological differences have been found among the populations of this species; however, the degree and pattern of intraspecific variation have not been surveyed using a sufficient number of samples.

Methods: For the taxonomic revision of H. hirosei, we conducted genetic and morphological surveys using samples collected throughout the distribution. Phylogenetic analysis using the cytochrome b region of mitochondrial DNA and population structure analysis using single nucleotide polymorphisms were conducted to evaluate the population structure within the species and the degree of genetic differentiation. Subsequently, a morphological survey based on multivariate and univariate analyses was performed to assess the morphological variation.

Results: Genetic analyses revealed three genetic groups (Tsurugi, Central, and Nanyo) within H. hirosei, with the Nanyo group distributed allopatrically from the others, and the Tsurugi and Central groups distributed parapatrically with the formation of a hybrid zone between them. The Nanyo group was morphologically distinguishable from the remaining samples, including the topotype of H. hirosei, based on a smaller body size and several ratio values of characters to snout-vent length, longer axilla-groin distance, shorter tail length, shorter internarial distance, longer upper eyelid length, and larger medial tail width. These results support the notion that the Nanyo group is an undescribed species. However, the remaining genetically differentiated groups could not be divided in the present study. Herein, we described the Nanyo group as a new species.

Hynobius oni sp. nov.
(Japanese name: Nan-yo-sanshouo)

Diagnosis: A large-sized species (adult SVL 73.6–87.5 mm in males) of the lotic-breeding Hynobius, breeding in montane streams; dorsum uniformly dark reddish brown and immaculate in adult; tips of fore- and hindlimbs adpressed on body scarcely meeting (overlap of −2.0 to 0.0 costal folds in males); fifth toe well developed; ova large, pigmentless; egg sacs relatively long and crescent in shape, with distinct whiptail structure on free end; larvae lack claws on their tips of fingers and toes; most similar to H. hirosei, but distinct based on its smaller body size, longer axilla-groin distance, shorter tail length, shorter internarial distance, longer upper eyelid length, and larger medial tail width. Hynobius oni is genetically closer to H. sematonotos than H. hirosei based on mtDNA; however, H. oni has no large markings on the body, in contrast to many silvery spots on H. sematonotos, and a larger SVL than H. sematonotos.

 Habitat of Hynobius oni in the type locality.

Etymology: The specific name is derived from the “Oni” in Japanese, which is a traditional Japanese demon. The habitats of the new species are areas where prior generations believed that the Oni and Ushi-oni, which is a type of Oni, occurred. The type locality is located in the Oni-ga-jo Mountains, which is considered to be the castle of the Oni.

In the present study, the actual genetic population structure and degree of genetic divergence within Hynobius hirosei, which has been reported to have large genetic intraspecies divergence, were evaluated using mtDNA and nuDNA markers (SNP). Phylogenetic analysis using mtDNA revealed three divergent lineages, including the Tsurugi, Central, and Nanyo groups (genetic distance: 6.9–10.3% in cyt b). Further, STRUCTURE analysis using SNP revealed that the Nanyo group is genetically isolated from the other groups and the Tsurugi and Central groups form hybrid zones. Morphological analyses also revealed that the Nanyo is distinct from the other groups. Collectively, these results strongly indicate that Nanyo group is a distinct species, and is referred to as H. oni sp. nov. in this study.
