Generic diagnosis

(adapted from Williams and Granara de Willink 1992; McKenzie 1967). Body narrowly to broadly oval, 2.0-3.8 mm long, 1.1-2.8 mm wide. Labium with three segments, about as long as the clypeolabral shield. Antennae, 8-segmented. Circulus present or absent. Legs well-developed, without translucent pores; apparently with a small denticle on the claw. Both ostioles well developed. Anal lobes well developed. Anal ring rounded, usually large and cellular with six long setae, but sometimes reduced, non-cellular, more or less removed from the posterior apex of the abdomen ( Anisococcus ephedrae (Coquillett)).

Dorsum. Dorsal tubular ducts with or without a rim, each orifice associated with one or more minute discoidal pores. Cerarii 13-17 pairs. Anal lobe cerarii, each with 7-20 conical setae on a sclerotized area, often with 3-7 auxiliary setae, remaining cerarii smaller, each with two or more conical setae plus an associated cluster of trilocular pores. Preocular cerarius always absent. Dorsal setae, slender and flagellate. Trilocular pores evenly distributed. Discoidal pores scattered and associated with tubular ducts, each smaller than trilocular pores. Multilocular disc pores absent.

Venter. Body setae flagellate. Trilocular pores evenly distributed. Discoidal pores scattered or associated with tubular ducts. Multilocular disc pores absent. Oral collar tubular ducts of one or more sizes, of various lengths and widths, with largest ducts, when present, on body margin, often associated with minute discoidal pores.
