| 4:08a | [Ornithology • 2022] Genome-wide SNPs confirm Plumage Polymorphism and Hybridisation within A Cyornis Flycatcher Species Complex
Abstract 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. Keywords: Cyornis, ddRADseq, introgression, phylogenetics, species complex 
CONCLUSIONS: 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. Elize Y. X. Ng, Siqi Li, Dezhi Zhang, Kritika M.

| 9:35a | [Botany • 2022] Stachys milasensis (Lamiaceae) • A New Species from Turkey
Abstract 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. Keywords: Anatolia, Bhattacharjee, Labiatae, taxonomy, Turkey, Eudicots
Stachys milasensis Ö.Güner, sp. nov. Diagnosis:—Stachys milasensis differs from the related S. swainsonii by having dense villous flowering stems, ovate to oblong-lanceolatecauline leaves, remote verticillasters, bilabiate calyx, oblong-ovate and spinescent-tipped calyx teeth and oblong-ovate nutlets. Etymology and vernacular name:— The epithet of the new species is derived from the name Milas district of Muğla where the type specimen was collected. The name of S. milasensis is proposed as “Milas Kayaçayı” in Turkish, according to the guidelines of Menemen et al. (2016).

| 9:45a | [Botany • 2022] Rotala biglandulosa (Lythraceae) • A New Species of Macrophyte from High-level Ferricretes of the northern Western Ghats, India
Abstract 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. Keywords: Lythraceae, New species, Phylogeny, Rotala, Western Ghats  Rotala biglandulosa Arun Pr. & Sardesai, sp. nov. Etymology The specific epithet ‘biglandulosa’ denotes bi-partite floral nectary glands. Arun Prasanth and Milind M. Sardesai. 2022.

| 10:02a | [Fungi • 2022] Gymnopus omphalinoides & G. schizophyllus (Agaricales: Omphalotaceae) • Emending Gymnopus sect. Gymnopus by including Two New Species from southern China
Abstract 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. Keywords: Morphology, new taxa, phylogeny, taxonomy
Gymnopus omphalinoides J.P. Li, T.H. Li & Y. Li, sp. nov. Diagnosis: Differs from G. volkertii Murrill in its striate or grooved pileus and smaller basidiospores (4.0–5.5 × 2.5–3 μm). Basidiomata mainly gregarious on decayed wood in broadleaf forest; pileus disc reddish orange to dark brown becoming paler with age; lamellae broad, adnate and ventricose; stipe glabrous. Etymology: The epithet ‘omphalinoides’ (Lat.) refers to the omphalinoid or Omphalina-like basidiomata of the new species.
Gymnopus schizophyllus J.P. Li, T.H. Li & Y. Li, sp. nov. Diagnosis: Differs from G. omphalinoides in its more or less depressed to slightly umbilicate pileus and more often split lamellar edge. Basidiomata mainly gregarious on decayed wood in broadleaf forest; pileus often pale orange to light brown; lamellae, adnate and generally split at the edge; stipe glabrous. Etymology: The epithet “schizophyllus” (Lat.) refers to the split edge of lamellae which is not so common in the genus.

| 11:41a | [Herpetology • 2022] Rhacophorus napoensis • A New Species of Rhacophorus (Anura: Rhacophoridae) from Guangxi, China
Abstract 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. Keywords: 16S rRNA, morphology, Rhacophorus napoensis sp. nov., Rhacophorus rhodopus, taxonomy
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.  Jing Li, Shuo Liu, Guohua Yu and Tao Sun. 2022. A New Species of Rhacophorus (Anura, Rhacophoridae) from Guangxi, China.
