In this paper we describe a new subgenus Neocyrtopsis (Paraneocyrtopsis) with two species originally described in Acosinetura Liu, 2000. We redescribe all the species in the subgenus Neocyrtopsis, and provide a key. Materials are deposited in the Shanghai Entomological Museum, CAS (SEM).

A synopsis of the species of Centris subgenus Xanthemisia Moure in Colombia is presented. The species identified are Centris ferruginea Lepeletier, C. lutea Friese and C. aureiventris, a new species from the Colombian Andes. Morphological characters of both sexes, distribution records and an identification key for the three species of the subgenus that occur in Colombia are provided.

Stenotabanus (Stenotabanus) clavijoi n.sp. is described based on two females collected in the states of Aragua and Tachira, Venezuela. This 59th species subgenus third from Diagnostic characters are: large relation to other subgenus; dorsum body dark brown black belly with pruinescence clear setae; frons inflated callus, square, black, shiny an upper extension; hyaline wings; yellowish legs; ab...

The subgenus Persexarthrus Voss, 1944 of the weevil genus Anthonomus Germar, 1817 is revised. Anthonomus (Persexarthrus) behnei sp. n. is described. A neotype of Bradybatus ornatoides Reitter, 1898 and lectotypes for Anthonomus baudueri var. abeillei Desbrochers des Loges, 1892, A. cyprius Marshall, 1925 and Neobradybatus variabilis Hoffmann, 1963 are designated. The five species of the subgenu...

Description of a new species from Australia, belonging to the subgenus Selenkothuria (Holothuria, Aspidochirotida). A dichotomous key of the thirteen valid species included in the subgenus is also given. The species H. perrieri Thandar, 1977 and H. spinea Cherbonnier, 1988 are considered as non valid.

We have developed a rapid and easy to perform fluorescence in situ hybridization test that allows specific identification of trypanosomes from the subgenus Trypanozoon, using peptide nucleic acid probes. Probes were designed to target subgenus-specific sequences on the multiple-copy 18S rRNA, greatly facilitating the detection of a single trypanosome.

A new subgenus, Exallomyia, of the genus Wyeomyia is established for three species previously included in the subgenera Davismyia and Dendromyia, and in the genus and nominate subgenus Sabethes. The terminalia of the holotype males of the three species, the midlegs of the males of two species, and the larvae and pupae of two species are illustrated.

Elucidating the evolutionary patterns of flower and inflorescence structure is pivotal to understanding the phylogenetic relationships of Angiosperms as a whole. The inflorescence morphology and anatomy of Philodendron subgenus Meconostigma, belonging to the monocot family Araceae, has been widely studied but the evolutionary relationships of subgenus Meconostigma and the evolution of its flowe...

A new black fly species, Simulium (Gomphostilbia) cauveryense sp. n., is described based on adult female, adult male, pupal and larval specimens collected from Kushalanagar, Karnataka, South India. This new species is placed in the decuplum subgroup of the batoense species-group within the subgenus Gomphostilbia. Keys to the species of the subgenus Gomphostilbia reported from India are provided...
