| 2:12a | [Entomology • 2022] Zaglyptogastra piyachudasringi • A New Species of Zaglyptogastra Ashmead (Hymenoptera: Braconidae: Braconinae) from Thailand
Zaglyptogastra Ashmead, 1900 was erected for a large, distinctive Braconinae wasp, Z. abbotti, collected in Lower Siam (Thailand) (Ashmead 1900). Although nine species are known from the Indo-Australian region, only three are recorded from mainland Indochina: Z. abbotti Ashmead, 1990 (Thailand), Z. vitalisi (Turner, 1919) (Thailand, Laos) and Z. vietnamica Long & Mai, 2015 (Vietnam) (El-Heneidy & Quicke, 1991; Long & Mai, 2015). In 2021, two further Asia species, Z. exilis Li, van Achterberg & Chen, 2021 and Z. tricolor Li, van Achterberg & Chen, 2021 were described from China (Li et al. 2021). Keywords: Hymenoptera, Braconidae, Braconinae   Zaglyptogastra piyachudasringi sp. nov. Distribution. Sakaerat Environmental Research Station, Nakhon Ratchasima province, Thailand. Host. Unknown.

| 2:14a | [Arachnida • 2022] Origin and Diversification of Free-living Stick Spiders of Sri Lanka including the Description of Four New Species of Rhomphaea and Two New Species of Neospintharus (Araneae: Theridiidae)
Abstract Sri Lanka is a biologically diverse South Asian island, and together with the Western Ghats (Southern India) is one of the 36 world’s most biologically diverse areas. Here, we investigated the origin and diversification of Rhomphaea and Neospintharus of Sri Lanka using sequences of three genes: mitochondrial cytochrome c oxidase I (COI) and 16S rRNA (16S); and nuclear 28S rRNA (28S). Our phylogeny included 32 taxa (30 ingroup and 2 outgroup). We used Bayesian Inference and maximum likelihood methods to reconstruct the placement of species, divergence time estimations and their foraging behavior with an emphasis on species from Sri Lanka. Our phylogenetic hypothesis support the monophyly of Argyrodinae as well as the monophyly of Rhomphaea, where Rhomphaea is a sister group of Neospintharus. Further, our analysis also suggests that Sri Lanka was colonized by Argyrodinae several times. Additionally, the following new species are described: Rhomphaea shanthi sp. nov., Rhomphaea jacko sp. nov., Rhomphaea martini sp. nov., Rhomphaea marani sp. nov., Neospintharus kandelensis sp. nov. and Neospintharus ohiyiaensis sp. nov.

| 6:11a | [Botany • 2022] Tulipa toktogulica (Liliaceae) • A Cryptic, Endangered New Species from the western Tien-Shan, Kyrgyzstan
Abstract Tulipa toktogulica (T. sect. Kolpakowskianae; Liliaceae) is a cryptic new species from the Toktogul area of the Jalal-Abad Region, Kyrgyzstan. It is similar to T. talassica, with which it shares the characteristically elongated tunic, but it is genetically and geographically distinct. It has a combination of morphological traits shared between the closely related species T. talassica, T. tetraphylla and T. ferganica, but the combination of its traits is unique. Unlike most other members of the genus, this new species has a scent. It is here also assessed as endangered due to its narrow range and continuing threats from overgrazing. Keywords: Central Asian flora, Tulipa sect. Kolpakowskianae, Tulipa subgenus Tulipa, Tulipa talassica, tulips, Monocots 
Tulipa toktogulica B.D.Wilson & Lazkov, sp. nov. This species is most similar to Tulipa talassica in its prolonged tunic but it has broad stamens like those of T. tetraphylla and only three leaves, unlike T. tetraphylla, which usually has four or more leaves. Flowers of the new species have a faint scent, which is not present in these other Central Asian species except T. kolbintsevii Zonneveld in Zonneveld & de Groot (2012: 1294). ... Etymology:—Named after the Toktogul region. We hope that naming it after this area will improve awareness of the diversity of the flora of this region and hence its conservation.

| 3:14p | [Ichthyology • 2022] Lethrinops atrilabris • A New Species of Deep-water Lethrinops (Cichlidae) from Lake Malawi
Abstract A new species of cichlid fish, Lethrinops atrilabris is described from specimens collected by trawling at a depth of around 90m off Monkey Bay, southern Lake Malawi. It is assigned to the genus Lethrinops on the basis of its vertical flank barring, lack of enlarged cephalic lateral line canal pores and the form of the lower jaw dental arcade. It can be distinguished from congeneric species by its male breeding dress of contrasting flank barring and dark ventral surface, most strikingly on the lips, throat and chest, its relatively small known maximum size (<75mm SL), large eyes (38-41% head length), laterally compressed body (depth 2.5-2.7 times max head width) and lower gillraker count (13-14). Keywords: New species, Lake Malawi, cichlidae, Lethrinops
Lethrinops atrilabris sp. nov. Diagnosis: the lower jaw dentition ‘Lethrinops-type’. Mature males with a melanic pattern of strongly contrasting dark vertical flank bars on a pale background, and a dark area on the jaws and the underside of the head and chest. In addition, the species can be identified by its relatively small adult body side (not known to exceed 73mm SL), large eye, short, rounded snout, ventrally-placed mouth, 13-14 ceratobranchial gill rakers and laterally compressed body. Etymology: ‘Atri-‘ from plural of the adjective ‘ater’ (Latin) = black + ‘labris’ from plural of labrum (Latin)= lip, in reference to the black lips of the males in breeding dress. George F. Turner. 2022. A New Species of Deep-water Lethrinops (Cichlidae) from Lake Malawi. Journal of Fish Biology. DOI: 10.1111/jfb.15208 |
