Description of a new species of the genus Ameletus Eaton, 1885 (Ephemeroptera, Ameletidae) from Yunnan, China.

ABSTRACT: A new species with primitive characteristics, Ameletus daliensis Tong, sp. nov., is described, based on the morphology of imago, larva and egg with molecular data of the mitochondrial COI from Mount Cangshan, Dali, China. The new species is closely related to one of the most primitive mayflies, Ameletus primitivus Traver, 1939, by sharing persistent mouthparts in the alate stage, but it can be distinguished from the latter by the morphological differences of the mouthpart remains, wings and genitals in the imaginal stage. Both morphological and molecular evidence support that A. daliensis Tong, sp. nov. is a new member of the genus Ameletus. The discovery of the new species could help understand the origin and evolution of the genus Ameletus.

A new species of Siphlonurus Eaton, 1868 (Ephemeroptera, Siphlonuridae) from Yunnan, China.

Project description:Siphlonurusdongxi Li & Tong, sp. nov. from Shangri-La City, Yunnan Province, China, is described based on egg, nymph, and winged stages. The new species is closely related to S.davidi (Navás, 1932), and can be distinguished by the colour of the imago, the forking point of MP, the penis, posterolateral spines of tergum IX of imagoes, and first abdominal terga nymph, as well as the structure of the egg. The new species and S.davidi have the same morphological and structural characteristics, such as the long cubital area with many intercalaries, cross veins between C, Sc, RA, and RSa1 surrounded with distinct pigments, the strong curvature of vein CuP in the forewing, the broad expansion of the hindwing, the membranous penis lobes fused without teeth, supporting the proposition of a new species complex, the Siphlonurusdavidi group. The structures of the penis and the egg of the new species could help understand the origin and evolution of the genus Siphlonurus.

Another new species of the genus Habrophlebia Eaton, 1881 (Ephemeroptera, Leptophlebiidae) from the Maghreb.

Project description:A new species belonging to the genus Habrophlebia Eaton, 1881 is described at the nymphal stage from the Rif Mountains of Morocco. This species presents unique features, such as the chorionic arrangement of the egg and the ornamentation of the posterior margin of abdominal tergites. It is compared to all west European Habrophlebia species and a table with discriminating characters is given. A phylogenetic reconstruction based on COI sequences fully supports the hypothesis of a new species in the Rif Mountains, with possible further distribution in southern Spain.

First record of Paegniodes Eaton, 1881 (Ephemeroptera, Heptageniidae) from Thailand with description of a new species.

Project description:A new species of Heptageniidae, Paegniodes sapanensis sp. nov., is described based on larvae, subimagos, eggs, and COI data. The mayfly genus Paegniodes Eaton, 1881 is reported for the first time from Thailand. The larva of the new species can be distinguished from other known Paegniodes species by i) lamellae of gill I ca 1/4 of fibrilliform portion and ii) mandibles and basal segment of maxillary palp without dense setae on margin. The subimago characters useful to distinguish this new species from previously known species are i) the median stripes on abdominal terga and ii) shape of the female subgenital and subanal plates. The genetic distance between the new species and P. cupulatus (Eaton, 1871) was approximately 11%. The morphological characters of the new species are discussed and compared to other known species.

First record of the genus Gratia Thomas (Ephemeroptera, Baetidae) from China with the description of a new species.

Project description:A new species of Baetidae, Gratiabaibungensis sp. n., is described and illustrated based on nymphal stage collected from the southeastern Tibet (Xizang) and the genus is reported for the first time from China. This new species can be readily differentiated from its congeners by the absence of a protuberance on the posterior margin of the abdominal tergum X, glabrate simple submarginal setae on the labrum, and the posterior margin of sterna VI-IX having much longer spatulate setae.

Description of two new sympatric species of the genus Leptolalax (Anura: Megophryidae) from western Yunnan of China.

Project description:The Asian leaf litter toads of the genus Leptolalax represent a highly diverse species group and currently contain 53 recognized species. During herpetological surveys in Yingjiang County, western Yunnan of China, we collected series of Leptolalax specimens from an isolated small fragment of montane evergreen forest. Subsequent study based on acoustic, morphological and molecular data reveals that there were three different species among the specimens sampled: while one of them belongs to Leptolalax ventripunctataus, the other two species represent unknown taxa and are described herein: Leptolalax purpurussp. nov. and Leptolalax yingjiangensissp. nov. The two new species can be distinguished from other congeners by the molecular divergences, acoustic data, and by a combination of morphological characters including: body size, dorsal and ventral patterns, dorsal skin texture, sizes of pectoral and femoral glands, degree of webbing and fringing on the toes and fingers, dorsum coloration and iris coloration in life. Our results further reveal that species diversity of the genus Leptolalax still remains highly underestimated and warrants further attention.

A new species of Cincticostella Allen, 1971 (Ephemeroptera, Ephemerellidae) from Yunnan, China and establishment of a new species complex.

Project description:Cincticostellajianchuan sp. nov. from Dali Bai Autonomous Prefecture, Yunnan Province, China, is described based on chorionic structure, nymph, and winged stages. The new species is closely related to C.fusca (Kang & Yang, 1995), but it can be distinguished in the male imago stage by its mesonotum and penes morphology, coloration, and the forking point of the stem of MA+Rs on the forewing; in the nymph stage, it can be distinguished by the length of the posterolateral projections of abdominal segment IX and the setation of the abdominal terga. Compared to other congeners, nymphs and male imagoes of the new species and C.fusca share several morphological characteristics, such as a larger body, mesothorax with medially notched anterolateral projections, forefemur without a subapical band of transverse spines of the nymphs, the area between C, Sc and R1 of the forewings distinctly pigmented, and an apical sclerite on the ventral face of the penes of the male imagoes, supporting the proposition of a new species complex, the jianchuan complex. The systematics of Cincticostella and related genera are discussed briefly.

A review of the genus Raveniola (Araneae, Nemesiidae) in China, with notes on allied genera and description of four new species from Yunnan.

Project description:The Chinese representatives of Raveniola Zonstein, 1987 are currently recognized to comprise seven species. Four new species - Raveniola montanasp. n. (??), Raveniola shangrilasp. n. (?), Raveniola songisp. n. (?) and Raveniola yunnanensissp. n. (?) - are described from the highlands of Yunnan Province, China. According to some characters (shape of the palpus, palpal tibia and tibia I in males) they can be placed together with Raveniola hebeinica Zhu, Zhang & Zhang, 1999 and with Raveniola guangxi (Raven & Schwendinger, 1995), comb. n., transferred here from Sinopesa Raven & Schwendinger, 1995. The current generic position of Raveniola xizangensis (Hu & Li, 1987) is confirmed. Other Chinese nemesiids referred previously to Raveniola are transferred to Sinopesa: Sinopesa chinensis (Kulczy?ski, 1901), comb. n., Sinopesa sinensis (Zhu & Mao, 1983), comb. n. and Sinopesa chengbuensis (Xu & Yun, 2002), comb. n. The relationships between these Asian genera and their relations to Afrotropical nemesiids are discussed.

Two new species of the genus Panorpa Linnaeus (Mecoptera, Panorpidae) from Yunnan, China.

Project description:Two new scorpionfly species, Panorpa reflexa sp. n. and Panorpa parallela sp. n., are described and illustrated from Yunnan Province, China. Panorpa reflexa can be readily differentiated from its congeners by the 3-shaped parameres in male genitalia. Panorpa parallela is unique for its parallel parameres in male genitalia. The number of Panorpa species is raised to four in Yunnan Province, and to 113 throughout China.
