| 3:09a | [Ichthyology • 2024] Koima gen. n. • A New Genus of nemacheilid loach (Cypriniformes: Nemacheilidae) from the Western Ghats, India
Abstract Koima, a new genus of nemacheilid loach, is described for Mesonoemacheilus remadevii Shaji 2002, and Nemacheilus monilis Hora 1921, both of which are endemic to the Western Ghats of southern peninsular India. Koima is distinguished from all other genera of family Nemacheilidae by its unique colour pattern comprising a yellowish-brown ground colour, single row of black spots on lateral line, all fins hyaline, and absence of a uniform banding pattern on dorsal side. Koima remadevii was initially identified as a species of Mesonoemacheilus Bănărescu & Nalbant 1982, from which it can be distinguished by the presence of a lower adipose crest, and an absence of a banding pattern on the dorsal side and on the caudal fin, while Koima monilis was initially identified as a species of Nemacheilus Bleeker 1863, from which it can be distinguished by the presence of a lower adipose crest, a narrow and deeply incised upper lip and having the fins hyaline. In the multi-gene phylogenetic analysis based on concatenated mitochondrial and nuclear gene sequences, Koima remadevii and K. monilis were recovered in a monophyletic group, sister to the endemic peninsular Indian nemacheilid, Schistura denisoni. Resolution of the identity of Koima remadevii and K. monilis contributes to our understanding of the phylogenetics of family Nemacheilidae, which is widely considered to be a polyphyletic group.

| 3:38a | [Botany • 2020] Arisaema kayahense (Araceae) • A New Species from Kayah State [Contributions to the Flora of Myanmar VI]
Abstract A new species Arisaema kayahense J. Murata is described from Kayah State, eastern Myanmar. This species was growing sideway from crevices of steep limestone rock under evergreen forests at about 1400 m elevation.
During field exploration to Kayah State, eastern Myanmar, in the early rainy season (June) in 2019, a strange Arisaema (Araceae) growing sideway from crevices of steep limestone rock was discovered. The species is characterized by having a leaf with verticillate leaflets with margins strongly revolute when opening and an inflorescence with a widely triangular ovate spathe blade and a small spadix appendix. Since it did not match any known species of the genus, it is here described as a new species Arisaema kayahense J. Murata. The leaf with verticillate leaflets and the spilodistichous leaf arrangement suggest that this species belongs to sect. Sinarisaema Nakai (Ohi-Toma et al. 2016, Murata et al. 2018). Arisaema kayahense J. Murata, sp. nov. Etymology: The specific epithet refers to the name of the state in eastern Myanmar where this species were discovered. Kayah State had been closed for a long time due to its local political situation, and opened only recently to outsiders including foreign nationals. Jin Murata, Mu Mu Aung, Nobuyuki Tanaka. 2020.

| 1:08p | [Entomology • 2024] Aspistomella duo, A. quinquincisa, A. tres, Ulivellia arcuata, U. pseudinsolita, ... • Revision of the Aspistomella Group of Genera (Diptera: Ulidiidae: Pterocallinae: Lipsanini)
Abstract Twenty-three species of the genera Aspistomella Hendel, 1909, Polyteloptera Hendel, 1909, and Ulivellia Speiser, 1929 occurring in South America (Colombia, Peru, Bolivia, and Brazil) form a monophyletic lineage sharing certain combinations of plesiomorphies and apomorphies with similar larval biology. The name Aspistomella Hendel, 1909 is a new senior subjective synonym of Paraphyola Hendel, 1909. The group of genera is extended by the addition of six known species, Aspistomella angustifrons (Hendel, 1909) comb. nov., A. crucifera (Hendel, 1909) comb. nov., A. lobioptera Hendel, 1909, A. heteroptera Hendel, 1909, A. lunata (Hendel, 1909) comb. nov., Polyteloptera apotropa Hendel, 1909, and Ulivellia inversa Speiser, 1929, and 17 previously unknown species. Aspistomella duo Kovac, Kameneva & V. Korneyev, sp. nov., A. enderleini Kameneva & V. Korneyev, sp. nov., A. garleppi Kameneva & V. Korneyev, sp. nov., A. obliqua Kameneva, V. Korneyev & Savaris, sp. nov., A. pachitea Kameneva & V. Korneyev, sp. nov., A. quinquincisa Kameneva & V. Korneyev, sp. nov., A. sachavaca Smit & Kameneva, sp. nov., A. schnusei Kameneva & V. Korneyev, sp. nov., A. steyskali Kameneva & S. Korneyev, sp. nov., A. teresensis Araújo, V. Korneyev & Savaris, sp. nov., A. tres Kovac, Kameneva & V. Korneyev, sp. nov., Ulivellia amnoni Smit, sp. nov., U. arcuata Kovac & Kameneva, sp. nov., U. laetitiae Smit, sp. nov., U. pseudinsolita Kameneva & V. Korneyev sp. nov., and U. tenoris Kovac & Kameneva sp. nov. are described. A key to the genera and species is given. Among the Lipsanini, this group of genera is easily recognised by the combination of an enlarged, anteriorly produced epistome (lower part of the face) and a low clypeus (in the other lipsanine genera the clypeus is high and the epistome is not enlarged), which supports its monophyly, and the differentiated short parafrontal setulae and long and strong frontal and interfrontal setae, which is a synapomorphy of a larger monophyletic lineage that also includes Chaetopsis Loew, 1868 and related taxa, as well as Amethysa Macquart, 1835, Euphara Loew, 1868 and their relatives. As far as is known, most species of this larger lineage are associated with various Poaceae plants. The species included here in the Aspistomella group are also associated with neotropical tall grasses: bamboo (Guadua) and wild cane (Gynerium). Aspistomella and Ulivellia larvae inhabit water-filled internode cavities (= “bamboo phytotelmata”) of living bamboo culms of Guadua angustifolia. Newly emerged larvae use tunnels made by lepidopteran borers (Crambidae caterpillars) to penetrate the hard bamboo walls. Aspistomella and Ulivellia larvae are saprophagous and adapted to an aquatic lifestyle. The last instar larvae jump easily and pupate in the soil. The external morphology, cuticular sensilla and cephalopharyngeal skeletons of the third instar larvae of five Aspistomella and Ulivellia species (one with unknown adult stage) were studied by light and scanning electron microscopy. The main features that allow the identification of larvae and puparia are the unique posterior spiracles and the structure of the abdominal creeping welts. The morphological characteristics of Aspistomella and Ulivellia larvae are compared with other Lipsanini and their feeding habits with other ulidiids. An identification key for Aspistomella and Ulivellia is given. The adaptations to life in bamboo phytotelmata found in both neotropical Aspistomella and Ulivellia and in oriental members of the closely related family Tephritidae are discussed.
