 Chen, Pan, Volynkin, Saldaitis & Benedek, 2022.

The subgenus Tatsipolia Benedek, Behounek, Floriani & Saldaitis, 2011 of the genus Dasypolia Guenée, 1852 is reviewed. Two new species, D. (T.) sejilaensis sp. nov. and D. (T.) cerritula sp. nov. are described from the Linzhi (Nyingchi) Prefecture in southern Xizang, China. The adults and the male and female genitalia of all species in the subgenus are illustrated. Additionally, Dasypolia (Auropolia) carlotta Floriani, Benedek, Behounek & Saldaitis, 2011 is reported from Xizang for the first time.

Type species: Dasypolia (Tatsipolia) ruficilia Benedek, Behounek, Floriani & Saldaitis, 2011, by original designation.

Diagnosis: Members of the subgenus are small moths (forewing length is 11-13 mm) externally similar to taxa of the subgenus Cteipolia. However, despite the external similarity, the subgenus is characterised by the following diagnostic features in the male genitalia: (1) The uncus is short but wide, triangular, dorso-ventrally flattened; (2) The harpe is reduced, tubercle- or spine-like; (3) The digitus is robust, thorn-like; (4) The juxta bears a medial process posteriorly; and (5) The phallus is relatively short but broad, with vesica bearing one or two clusters of spine-like cornuti. In the female genitalia, the broad ostium bursae and the sideways curved ductus and corpus bursae are characteristic for the subgenus.

Distribution: Species of the subgenus are known only from south-western China (Sichuan and southern Xizang).

[Herpetology • 2022] Rhacophorus napoensis • A New Species of Rhacophorus (Anura: Rhacophoridae) from Guangxi, China

 Rhacophorus napoensis
Li, Liu, Yu & Sun, 2022

Napo tree frog | 那坡树蛙  ||  DOI: 10.3897/zookeys.1117.85787

Based on morphological and molecular evidence of five male adult specimens collected from Napo County, Baise City, Guangxi Zhuang Autonomous Region, China, we describe a new species of Rhacophorus, Rhacophorus napoensis sp. nov. This new species is similar to Rhacophorus rhodopus Liu & Hu, 1959 and Rhacophorus bipunctatus Ahl, 1927 in morphology, but it can be distinguished from the latter two by the following morphological characteristics: head width is greater than head length, snout pointed, loreal region oblique, tympanum distinct, maxillary teeth distinct, tongue cordiform, external single subgular vocal sac, tibiotarsal articulation reaches the snout, tibia length is greater than foot length and slightly greater than half of snout-vent length, and single outer metatarsal tubercle is flat. The phylogenetic tree constructed based on 16S rRNA sequence shows that all individuals of this species clustered into the same clade, and genetically this new species differs from R. rhodopus and R. bipunctatus by 7.71% and 7.98% in 16S rRNA sequences, respectively.

 Rhacophorus napoensis sp. nov.
Diagnosis: Morphologically, there are the following differences between Napo County specimens and other species belonging to Rhacophorus: (1) Medium body size (adult males SVL 38.6–43.6 mm); (2) snout pointed, projecting beyond margin of lower jaw in ventral view, and the tip has a distinct bulge; (3) tympanum distinct, rounded; (4) maxillary teeth distinct; (5) tongue cordiform, notably notched posteriorly; (6) external single subgular vocal sac; (7) the tibiotarsal articulation reaches the snout; (8) TIL longer than FL and slightly longer than half of SVL; (9) entire web between fingers and toes; (10) single inner metatarsal tubercle, flat; (11) banding exists in dorsal surface of limbs posterior part of dorsum; (12) two to three black spots at axillary region; (13) web is not black; and (14) dorsal color hoary with numerous black spots when the species is kept in preservative.

Etymology: The specific epithet is named for the type locality. We suggest the English common name as “Napo tree frog” and the Chinese common name as “那坡树蛙”.

Distribution and ecology: The new species was found near several large rocks in the bushes, 306 m southeast of Nongyao, Napo County, Baise City, Guangxi Zhuang Autonomous Region, China (Fig. 7). Vocal recordings and tadpoles of this new species were not collected.

[Fungi • 2022] Gymnopus omphalinoides & G. schizophyllus (Agaricales: Omphalotaceae) • Emending Gymnopus sect. Gymnopus by including Two New Species from southern China

 Gymnopus omphalinoides J.P. Li, T.H. Li & Y. Li,

in Li, Antonín, Gates, Jiang, ... et Deng, 2022. 

Based on phylogenetic analyses, some newly studied Chinese mushroom specimens were found to represent two distinct species within the genus Gymnopus. Along with G. fusipes (sect. Gymnopus) they form a distinct clade with high support, although their macromorphological characters seem to be closer to members of Gymnopus sect. Levipedes or sect. Vestipedes (Collybiopsis). When examined in detail, their micromorphological characters, especially the type of pileipellis, support them as new members of G. sect. Gymnopus. Therefore, two new species, G. omphalinoides and G. schizophyllus, and the emended circumscription of sect. Gymnopus are proposed in this paper. Detailed morphological descriptions, colour photos, illustrations of the two new species, morphological comparisons with similar taxa and the molecular-phylogenetic analyses of the combined nrITS and nrLSU data are presented. A key to the known species of G. sect. Gymnopus is also presented.

[Botany • 2022] Rotala biglandulosa (Lythraceae) • A New Species of Macrophyte from High-level Ferricretes of the northern Western Ghats, India


Rotala biglandulosa Arun Pr. & Sardesai, 

in Prasanth & Sardesai, 2022. 

A new species, Rotala biglandulosa, is described here from the northern Western Ghats, Maharashtra, India. It is closely similar to R. juniperina but can be distinguished morphologically based on having stamens arising from base of the floral tube, the presence of three bipartite nectary gland, and capsules exceeding the floral tube. A phylogenetic study based on nrITS and psbA–trnH loci also confirmed the status of R. biglandulosa as a distinct species.

[Botany • 2022] Stachys milasensis (Lamiaceae) • A New Species from Turkey

 Stachys milasensis
Güner. 2022

Stachys, among the largest genera of Lamiaceae, includes approximately 370 species (435 taxa) and has a subcosmopolitan distribution. Here, based on their distinctive features of morphological characters, Muğla (Turkey) specimens are determined to represent a distinct species than relevant Stachys species in Turkey and Greece. Stachys milasensis Ö.Güner, described as a new species, belongs to section Swainsoniana and is an endemic species to Turkey. The newly described species shows affinity with S. swainsonii growing in Greece but differs from it in dense villous flowering stems, ovate to oblong-lanceolate cauline leaves, bilabiate calyx and oblong-ovate calyx teeth and oblong-ovate nutlets. In addition to morphological differences, the new species is geographically isolated from S. swainsonii. With this addition, the number of Turkish Stachys species has reached 94 (121 taxa), and 65 (53.7%) of these taxa are endemic.

[Ornithology • 2022] Genome-wide SNPs confirm Plumage Polymorphism and Hybridisation within A Cyornis Flycatcher Species Complex

in Ng, Li, Zhang, Garg, ... et Lei, 2022. 

Morphology has been a leading taxonomic guiding light to systematists for the last couple of hundred years. However, the genetic and – more recently – genomic revolution have produced numerous demonstrations of erroneous classifications that were based on labile morphological traits. We used thousands of genome-wide markers to shed light on evolutionary dynamics in a confusing and taxonomically obscure group of Asian Cyornis flycatchers. Using genomic data, we corroborated recent findings based on three mitochrondrial and five nuclear genes that the two taxa hainanus and klossi which were previously treated as separate species (Cyornis hainanus and Cyornis rubeculoides klossi, respectively) are genomically homogeneous and form a single species, C. hainanus. We also uncovered a novel case of interbreeding between C. hainanus and a non-sister species, C. glaucicomans, illustrating these flycatchers' ability to hybridise in marginal situations even after substantial times of divergence. Our study illustrates how genome-wide loci can shed light on complicated taxonomic problems, resulting in a better integration of phenotypic and genotypic data.

The classification of Cyornis flycatchers has undergone substantial change over the last two decades, resulting in taxonomic rearrangements, in particular the synonymisation of the genus Rhinomyias with Cyornis (Sangster et al., 2010; Zhang et al., 2016; Zuccon & Ericson, 2010). Our study demonstrates that population-genomic and phylogenomic methodologies can effectively be applied to disentangle the complicated evolutionary history of cryptic species complexes such as the Cyornis flycatchers. Our ddRADseq data set confirms the remarkable case of incongruence between plumage and genomic divergence that has misled previous taxonomists into erroneous classifications (Zhang et al., 2016). Our results also show a novel interbreeding event between two non-sister species.

in Dias, Udulutsch & Pirani, 2013. 

A new species of Metrodorea (Rutaceae), M. concinna, is described and illustrated, and morphological, molecular phylogenetic, and distributional support for the new taxon and its relationships with morphologically similar species, as well as with sympatric ones, are explored. The new species is endemic to semideciduous forests of southeastern Bahia, eastern Brazil. It is distinct from other species of the genus mainly by the combination of shrubby to treelet habit, (sub)sessile leaves, sessile leaflets without conspicuous, dark glands on the abaxial surface, and by each carpel bearing one dorsal apophysis. In addition to the diagnostic morphological features, molecular data provide further support to the new taxon.

กระเจียวสุพรรณ || 

Two new species of Curcuma L. are described. The first species, Curcuma suphanensis P. Saensouk, Boonma, Rakarcha, Maknoi, Wongnak & S. Saensouk sp. nov. was found in Suphan Buri province, Central Thailand, and the second species namely C. rosea P. Saensouk, S. Saensouk & Boonma sp. nov. was found in Uthai Thani province, Southwestern Thailand. Both species fall into the subgenus Ecomata because of the lack of conspicuous coma bract, and the presence of epigynous glands. This brings the number of species in this subgenus worldwide to 37 species. Living specimens and spirit specimens of both new species were collected from their natural habitats, morphological attributes measured, and compared to all existing species. Neither species match any previously-described species, therefore, both of them are new species to science. The first was named Curcuma suphanensis based on its province of origin (Suphan Buri Province), and the second species was named Curcuma rosea, on account of its pinkish bracts. Morphological descriptions along with their illustrations, notes on their ecology, etymology, and distributions, are presented along with a revised key to species of Curcuma subgenus Ecomata worldwide to facilitate identification.

[Botany • 2022] Sinosenecio yangii (Asteraceae: Senecioneae) • A New Species from Guizhou, China


 Sinosenecio yangii D. G. Zhang & Q. Zhou,

in Peng, Zhang, Deng, Huang, ... et Zhou, 2022. 

A new species Sinosenecio yangii D.G. Zhang & Q. Zhou (Asteraceae, Senecioneae) from Guizhou Province, China, is described and illustrated based on its morphological characteristics and molecular evidence. It closely resembles S. confervifer and S. guangxiensis, the former in the scapigerous habit and smooth and glabrous achene surface, the latter in the calyculate involucre and purple abaxial leaf surface, and both in the shape and indumentum of leaf lamina, but differs markedly from the latter two in having fewer capitula and epappose achenes. Phylogenetic analysis based on nrITS and ndhC-trnV sequences shows that this new species belongs to the S. latouchei clade and is sister to S. guangxiensis with moderate support.

Morphological observation (Fig. 1) showed that S. yangii, S. confervifer, and S. guangxiensis share obvious resemblance in the leaf blade shallowly undulate and suborbicular, adaxially densely to sparsely villous and abaxially sparsely pubescent or nearly glabrous (Table 2). In addition, S. yangii is similar to S. confervifer in the stem leafless or with 1–2 bract-like leaf and smooth achene surface, and to S. guangxiensis in the calyculate involucre. Nevertheless, S. yangii differs from both species in having fewer capitula (usually 1–3) and epappose achenes. The metaphase chromosomes of this species were counted to be 2n = 48 (Fig. 2A). The achene surface was glabrous and smooth (Fig. 2B) and the anther endothecial cell wall thickenings were polarized and radial (Fig. 2C). 

Etymology: The species was named after Professor Qin-er Yang, an expert in the field of Asteraceae at the Chinese Academy of Sciences. The Chinese name is given as “亲二蒲儿根” (qīn èr pú ér gēn).

Distribution and habitat: Sinosenecio yangii is known from Lihua Town, Libo County, Guizhou Province, China (Fig. 6). It was collected from a rock cliff by the side of a rural road in this town, at an altitude of 347 m.
