Six species of the subgenus Ochlerotatus and one species of the subgenus Coetzeemyia of the genus Aedes in the Afrotropical Region are treated in a pictorial key based on diagnostic morphological features. Brief remarks on the new reclassification of the genus Aedes are also included.

A reexamination of the holotypes of Pylocheles cubensis Ortiz & Gómez, 1986 and Pylocheles (Bathycheles) chacei Forest, 1987 has shown that these two deep-water taxa are identical. Pylocheles cubensis is the senior synonym and is assigned to the subgenus Bathycheles Forest, 1987, replacing P. (B.) chacei as the single Western Atlantic representative of the subgenus. Pylocheles (Bathycheles) cub...

Four new water mite species of the subgenus Arrenurus (Megaluracarus) from lakes and ponds in Mexico are described and illustrated: Arrenurus (Megaluracarus) anitahoffmannae sp. nov., A. olmeca sp. nov., A. maya sp. nov., and A. urbanus sp. nov. With these species the number of known species of this subgenus in Mexico increases to 21.

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.
