A taxonomic synopsis of the orchid genus Habenaria in New Guinea and adjacent islands is presented. We confirmed the occurrence of 27 Habenaria species in study area. Sixteen of these are endemic and were not so far found outside New Guinea. Morphological characteristics and illustrations of floral segments of taxa are presented. One new species of Habenaria is described. Four neotypes are selected. An updated key to species groups and species occurring in the study area is provided. The importance of diagnostic floral characters in Habenaria is discussed.

Species within Gennadas differ from each other largely only in male (petasma) and female (thelycum) copulatory characters, which were restudied in scanning electron microscopy and used as a basis for phylogenetic analyses. Twenty-six petasma characters and 49 thelycum characters were identified. All 16 recognized species of Gennadas and Aristaeomorpha foliacea (outgroup) were included as terminals. Four robust monophyletic clades were retrieved, described and diagnosed as new species groups. The thelycum characters had greater impact on tree topology and supported deeper nodes than did the petasma characters. We hypothesize that features of the thelycum evolved first followed by aspects of the petasma. Relatively more conservative characters include parts of the sternites of the thelycum and of the petasma, while the scuti and protuberances on the thelycum and the shape and subdivisions of the petasma lobes are evolutionarily plastic. We identified two groups of copulatory characters, which are likely coupled functionally and interlinked evolutionarily: (i) the external part of the petasma and the posterior part of the thelycum and (ii) the internal part of the petasma and anterior part of the thelycum. We reconstruct possible mating position during copulation for each of the new species groups presented here. We also present an updated key to genera of Benthesicymidae and key to species of Gennadas .

AbstractThe species of Synophromorpha Ashmead (Hymenoptera: Cynipidae) are reviewed. One new species is described (Synophromorpha kaulbarsi; type locality: Naupan, Puebla, Mexico). The previously described species (S. rubi Weld, S. sylvestris (O.S.), and S. terricola Weld) are redescribed, and a key to species is presented. All species are illustrated for the first time. Synophromorpha sylvestris is designated type-species for the genus and a lectotype is chosen. Hypotheses on the phylogenetic relationships between the species of Synophromorpha are presented.

The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.

The micropolydesmoid millipede family Haplodesmidae is here recorded from Cambodia for the first time through the discovery of the first, new species of the genus Eutrichodesmus Silvestri, 1910: E. cambodiensissp. nov. This new species is described from two limestone habitats in Kampot Province, based on abundant material. It is easily distinguished from all related congeners by the following combination of characters: body greyish-brown; limbus roundly lobulate; solenomere partially divided from acropodite by a digitiform lobe, but without hairpad. Brief remarks on the previously-proposed “pecularis-group” are provided and a second group, the “demangei-group”, is established and discussed on the basis of morphological evidence, updating the number of recognised species groups of Eutrichodesmus to two. Detailed morphological illustrations, photographs and a distribution map, as well as remarks on its habitat and mating behaviour of the new species are presented. Furthermore, the current distributions of all 55 presently-known species of Eutrichodesmus are provided and a key to all 23 species that occur in mainland Southeast Asia is given.

A New Species

Egyptian and Saudi Arabian Thyridanthrax spp. collected in field trips or preserved in the Efflatoun’s insect collection in Cairo University were taxonomically studied. One new species, T. elegansoides sp. nov., is herein described, and two species, T. decipulus (Austen) and T. polyphemus (Wiedemann), are newly recorded from Egypt. Ten species are treated: one species from the Kingdom of Saudi Arabia, T. anomalus Greathead; two species from Egypt and the Kingdom of Saudi Arabia, T. decipulus (Austen) and T. perspicillaris (Loew); and seven species from Egypt: T. elegans (Wiedemann), T. elegansoides sp. nov., T. griseolus (Klug), T. incanus (Klug), T. lotus (Loew), T. obliteratus (Loew), and T. polyphemus (Wiedemann). Taxonomic comments, an identification key to species, diagnoses, and photographs of some species and genitalia are provided. Based on wing morphology and male genitalic characters, T. lotus clearly does not fit in the genus Thyridanthrax, and may need to be placed elsewhere, nevertheless it is not clear whether it can be included in any of the other currently recognized genera in the tribe Villini. It is here kept in Thyridanthrax until a more rigorous study can be conducted to better ascertain its position in the Villini.

According to previous reports, the number of cicada species known from Vietnam is 131; these represent 45 genera. Neotanna yunnanensis Lei et Chou, 1997 and Neotanna sinensis Ouchi, 1938 are transferred to Tanna Distant, 1905 to become Tanna yunnanensis (Lei et Chou, 1997) comb. nov. and Tanna sinensis (Ouchi, 1938) comb. nov., Proretinata vemaculata Chou & Yao, 1986 is transferred to Angamiana Distant, 1890 to become Angamiana vemacula (Chou et Yao, 1986) comb. nov.. Twenty additional species are here recorded for the fauna of Vietnam for the first time: Scolopita lusiplex Chou et Lei, 1997, Hea fasciata Distant, 1906, Hea yunnanensis Chou et Yao, 1995, Katoa chlorotica Chou et Lu, 1997, Mogannia effecta Distant, 1892, Nipponosemia guangxiensis Chou et Wang, 1993, Ambragaeana ambra Chou et Yao, 1985, Balinta tenebricosa (Distant, 1888), Gaeana cheni Chou et Yao, 1985, Gaeana hainanensis Chou et Yao, 1985, Sulphogaeana dolicha Lei, 1997, Paratalainga yunnanensis Chou et Lei, 1992, Formotosena seebohmi (Distant, 1904), Angamiana vemacula (Chou et Yao, 1986), Pomponia backanensis sp. nov., Purana guttularis (Walker, 1858), Tanna yunnanensis (Lei et Chou, 1997), Tanna sinensis (Ouchi, 1938), Euterpnosia ruida Lei et Chou, 1997, Inthaxara flexa Lei et Li, 1996, and Sinosemia shirakii Matsumura, 1927. One of these, Katoa chlorotica, is the first representative of the subfamily Tettigadinae and the tribe Tibicini for Vietnam. One new species, Pomponia backanensis sp. nov., is described and a key to species of Vietnamese Pomponia is provided.
