Summary.A synopsis is presented for the classification of the 78 genera and subgenera of C eratopogonidae of the w orld. Taxonom ic keys are given for the separation of the genera. A short history is given for the classification of the fam ily. The biting m idges of this fam ily include im portant bloodsucking pests, vectors of several anim al diseases, pollinators of seve ral tropical crops, and parasites and predators of other insects.

New Haemoproteidae parasites of Chiroptera in ThailandSUMMARY. Hipposideros larvatus of Thailand are parasitized by two new Haemosporidia : a) Nycteria brucechwatti n. sp. can be differentiated from all other Nycteria species by the schizonts which are the largest in the genus and by the absence of accessory chromatin dots in the game tocytes ; Biguetiella minuta n. g. n. sp. has very small intra-hepatocytic schizonts (< 15 µm) and gametocytes of the « falciparum » type. These two species are considered as vicariant forms of parasites of M in iopterus, namely Polychromophilus and Bloccala. The subgenus B ioccala is raised to genus status and problems related to the study of polyparasitic infections of the same host are discussed.
Forcipomyia (Pterobosca) hutsoni n.sp. is described and figured from adults of both sexes and from putatively identified larvae and pupae. The species is common on Aldabra Atoll in the Indian Ocean. Most adult females were taken from the wings of Odonata. Immature stages were found in Pandanus leaf axils and are the first to be described for the subgenus Pterobosca. Characters of the three stages show that biting midges of this subgenus are most closely related to the subgenera Phytohelea, Trichohelea and Rhynchoforcipomyia. The subgenera Thyridomyia, Synthyridomyia and probably Blantonia fall in a second section of the genus, while Lasiohelea forms a third and intermediate section.
The Atrichopogon jacobsoni Species Group is diagnosed and a key is presented to distinguish the seven known species, which occur in the Oriental and Australasian Regions. The common and widespread species, Atrichopogon jacobsoni (de Meijiere), is redescribed and its habits are summarized. Two new species are described: Atrichopogon carinatus from West Malaysia, and A sinuosus from six countries in Southeast Asia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
