Taxonomy and molecular phylogeny of the Asian Paraleucophenga Hendel (Diptera,Drosophilidae)

This paper reports on nine Asian species of the genus Paraleucophenga, of which four are new to science: Paraleucophenga brevipenis sp. nov. , Paraleucophenga hirtipenis sp. nov. , Paraleucophenga longiseta sp. nov. , and Paraleucophenga tanydactylia sp. nov. We also report on a new synonym, Paraleucophenga shanyinensis Chen & Toda, 1994 syn. nov. A key to all of the species examined, based on morphological data, is provided, together with a ‘molecular’ key to seven Paraleudophenga species based on DNA sequence data of the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene. The phylogenetic relationships among seven Paraleucophenga species are reconstructed based on DNA sequences of the mitochondrial ND2 gene, using two Leucophenga species as outgroups. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155 , 615–629.     

Description of a new Brazilian species of Mycodrosophila (Diptera,Drosophilidae) with emphasis on the morphology of phallic sclerites

Mycodrosophila is a cosmopolitan genus of Drosophilidae that comprises approximately 130 species with mycophagous habitats. In this study, we described a new species of Mycodrosophila based on morphological traits and included details of the male terminalia. The holotype is from Eugênio Lefévre, locality in Campos do Jordão municipality, SP, Brazil, located in the Atlantic rainforest biome and was sampled in the 1930s.     

Molecular phylogenetic analysis of the Amiota apodemata and Amiota sinuata species groups (Diptera: Drosophilidae), with descriptions of four new species

The phylogenetic relationships among the East Asian species of the apodemata and sinuata species groups of the genus Amiota were investigated based on DNA sequences of the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene. A total of 23 samples of 12 species were employed as in‐group taxa, and one sample for each of four other Amiota species were used as out‐groups. The results suggested with strong confidence the monophyly of both the apodemata and the sinuata groups, whereas the monophyly of the ‘apodemata group + sinuata group’ cluster was less supported. Based on its geographical distribution, the origin of the sinuata group is supposed to be southern China. Four new species were described from Guangxi and Yunnan, China: Amiota reikae Xu & Chen sp. nov. , Amiota guiensis Xu & Chen sp. nov. , Amiota hesongensis Xu & Chen sp. nov. , and Amiota polytreta Xu & Chen sp. nov. © 2013 The Linnean Society of London

Three new species of the subgenus Parapenthecia from the Oriental Region (Diptera: Drosophilidae: Apenthecia)

Three new species of the subgenus Parapenthecia of the genus Apenthecia are reported from the Oriental Region: A. (P.) heterochaeta Chen and Toda, sp. nov. from Indonesia, and A. (P.) hispida Chen and Toda, sp. nov. and A. (P.) litongi Cao and Chen, sp. nov. from south China. Interestingly, the last species lacks a very peculiar character, the swollen or scale‐like orbital setae, which are commonly seen in all other species of the genus Apenthecia. A key to all species of the subgenus Parapenthecia is provided.     

Intra‐specific variability in Rhinoleucophenga punctulata populations (Diptera: Drosophilidae) from Neotropical biomes: Combined analyses of morphological and molecular data

Despite the fact that Drosophilidae is a very diverse and well‐studied taxon, the New World genus Rhinoleucophenga is yet poorly understood even in regard to species distribution and morphological variability pattern. In this sense, R. punctulata is a species widely distributed in the Neotropical region. Specimens of R. punctulata were collected from different biomes in Brazil: Pampa, Cerrado and Caatinga sensu strictu, and a southern Amazonian savannah enclave area. Geographical variations in the external body morphology and in the morphology of spermatheca were noticed among the different populations. The hypothesis that each population could be a different species was tested through molecular data. A fragment of the mitochondrial cytochrome c oxydase subunit I (COI) gene was sequenced to perform phylogenetic analyses through neighbor‐joining and Bayesian inferences. Pairwise genetic divergences of COI sequences were calculated using DNA barcode premises. The analyzed populations presented different variation levels in both morphology and molecular traits. However, new species were not proposed because the intra‐population nucleotide variations exceeded the inter‐population ones. The noticeable morphological and genetic variations revealed among the four studied populations of R. punctulata in different biomes of Brazil suggest the necessity that morphological, distributional and molecular data at the population level should be integrated into complementary datasets to better understand the biological diversity of Rhinoleucophenga through Neotropical environments.     

The first record of genus Bruggmanniella (Diptera: Cecidomyiidae) from Taiwan with description of a new species inducing bud galls on Neolitsea parvigemma (Lauraceae)

The genus Bruggmanniella Tavares is newly discovered from Taiwan and Bruggmanniella brevipes sp. n. is described as new to science. This is the southernmost species of Bruggmanniella found in the Old World. Furthermore, the gall midge induces bud galls on Neolitsea parvigemma (Hayata) Kaneh (Lauraceae), an endemic species in Taiwan, and the plant genus Neolitsea is the third host genus of Lauraceae-associated Bruggmanniella in East Asia. The knowledge of its distribution and host information provide us to shed the light on evolutionary and biogeography issue of East Asian Bruggmanniella.www.zoobank.org/urn:lsid:zoobank.org:pub:820320EC-17BC-4E00-A401-2DBDA3EEE9C4     

A new black fly species of the subgenus Gomphostilbia (Simulium: Simuliidae: Diptera) from India

Simulium (Gomphostilbia) agasthyamalaiense sp. nov. is described based on adults, pupae and mature larvae from a medium-flowing stream of Southern Western Ghats, India. This new species is placed in the Simulium batoense species-group of the subgenus Gomphostilbia Enderlein. This new species is characterized in the female by a scutum with three brownish-black longitudinal vittae and the hind basitarsus 5.7 times as long as wide; in the female by the large facets of upper eye with 20 vertical columns and 19 horizontal rows; in the pupa the respiratory gill with medium-long common basal stalk; and in the larva arrowhead-shaped postgenal cleft. Taxonomic notes are provided for this new species and it can be distinguished from closely related species of S. (G.) peteri. Keys are constructed to distinguish this species from ten species of the batoense species-group recorded in India.www.zoobank.org/urn:lsid:zoobank.org:pub:1D1CFEE5-A762-4F68-9EAE-9E31133146C0

Revision of Asian species of the Drosophila melanica species group (Diptera: Drosophilidae), with a description of a new species from Vietnam

A new species of the Drosophila (Drosophila) melanica species group (Diptera: Drosophilidae), Drosophila denruoi Suwito & Watabe, sp. nov., is described from northern Vietnam. It is proved by crossing experiments that reproductive isolation is complete between this species and other morphologically similar species. Larval ganglion cells of D. denruoi possess 2n = 12 chromosomes, comprised of four pairs of acrocentric, one pair of metacentric and one pair of micro‐chromosomes. This is the largest number of acrocentric chromosomes in the group and implies that the species has the most primitive chromosomal configuration in the melanica group. Based on the results of crossing experiments and close morphological examination, Drosophila pengi Okada & Kurokawa, 1957 from central Japan, once regarded as a synonym of Drosophila tsigana Burla & Gloor, 1952, is shown to be distinct from D. tsigana. Drosophila pengi is thus resurrected as a member of the melanica group. We synonymize Drosophila bisetata Toda, 1988, described from central Myanmar, with D. pengi. In addition, a population from Guizhou, southwestern China, once regarded as D. tsigana, is also identified as D. pengi. These populations from central Myanmar and southwestern China share the diagnostic characters of D. pengi. At the same time, it is reconfirmed that the Hokkaido population is conspecific with European D. tsigana. Furthermore, another species, Drosophila longiserrata Toda, 1988 described from central Myanmar, is synonymized with Drosophila afer Tan, Hsu & Sheng, 1949 from China, based on their having identical karyotypes and external morphology.     

Notes on the species of Naarda Walker, 1866 (Lepidoptera: Erebidae,Hypeninae) from mainland China,with the description of a new species and establishment of a new synonymy

Naarda pectinata Sugi, 1982 is synonymised with N. postpallida on the basis of material from Vietnam. This species can immediately be recognised by its dark grey forewing, white hindwing and several genital characters. The female genitalia of N. postpallida, together with those of N. lingualis Tóth and Ronkay, 2015 are presented for the first time. Naarda macrostigma sp. n. is described. The hitherto known nine Chinese Naarda species are listed. With nineteen figures.www.zoobank.org/urn:lsid:zoobank.org:pub:092AE905-08AA-4818-BDA8-2B9EF150793A     

Two new species of Chrysis Linnaeus (Hymenoptera,Chrysididae) from Iran

The Iranian species in the Chrysis pulchella and C. varidens species groups are investigated. Six species are recognized, two of which are described for the first time: Chrysis gamberoonensis Farhad, Rosa and Talebi sp. nov. and Chrysis brunneamarginata Farhad, Rosa and Talebi sp. nov.. Chrysis gamberoonensis Farhad, Rosa and Talebi sp. nov. belongs to the C. pulchella group and is recognizable within this species group by its unique blue body coloration, scattered mesosoma punctures, polished pit row with elongated pits, and a small median tooth on the lateral edge of metasomal tergum 3. Chrysis brunneamarginata Farhad, Rosa and Talebi sp. nov. belongs to the C. varidens group and is recognizable by the usually colorless apical rim of metasomal tergum 3, and the unique shape of the anterior corners of the scutellum which are enlarged, thickened and directed backward covering the axillary trough. Dichotomous keys and distributional data for Iranian species included in these species groups are provided. Chrysis schwarzi Linsenmaier, 1968 is raised to species rank. The number of Iranian Chrysis species and subspecies is raised to 122.www.zoobank.org/urn:lsid:zoobank.org:pub:F419F860-3B90-4679-9A19-2CF5C255AE6B

Taxonomic study of the Drosophila auraria species complex (Diptera: Drosophilidae) with description of a new species

The Drosophila auraria species complex, especially from the Ryukyu archipelago and Taiwan, was reviewed. A new species, D. neoasahinai Watada and Kondo, sp. nov., was described from Okinawa‐jima and surrounding islands. Two synonymies were proposed on the basis of the present and previous morphological comparisons and cross experiments: (i) D. yuwanensis Kim and Okada, 1988 as a junior synonym of D. asahinai Okada, 1964; and (ii) D. quadraria Bock and Wheeler, 1972 as a junior synonym of D. triauraria Bock and Wheeler, 1972. A laboratory stock (no. 14020–0011.01) maintained in the Drosophila Species Stock Center at the University of California, San Diego and so far designated as D. rufa Kikkawa and Peng, 1938 was identified as D. tani Cheng and Okada, 1985, based on morphology.
