The Ceratopogonidae, biting midges, are a cosmopolitan group of small flies, a number of species of which have females that feed on vertebrate blood.

Four subfamilies are recognised, the most divergent of which includes the genus Leptoconops which has eyes widely separated on top of the head (vs closely approximated in other subfamilies) and lacks the crossvein r-m in the wing (Downes & Wirth 1981). Forcipomyiinae have well-developed empodia, at least in females, and strongly curved claws (Downes & Wirth 1981).

Characters (from Downes & Wirth 1981): Small flies, 1–6 mm long, slender to moderately robust. Antenna with 11–13 flagellomeres, showing marked sexual dimorphism; female with five distal flagellomeres elongated and differing from proximal flagellomeres in many details; male with pedicel greatly enlarged and containing a specialised Johnston’s organ, flagellomeres 1–8 usually bearing whorls of long setae giving characteristic plumose appearance. Proboscis about as long as head; palpus slightly longer. Female with biting and sucking mouthparts, consisting of a rigid labrum, blade-like mandibles and laciniae, and a hypopharynx, each typically with apical armature; females in non-biting species and all males with proboscis weaker and armature reduced. Palpus five-segmented; segments 1 and 2 sometimes poorly developed; segment 3 with sensory organ enclosed in a pit or on surface; segments 4 and 5 occasionally fused. Wings held horizontally at rest one above the other, narrower in male than in female; apex evenly rounded. Venation characterized by compact radial system lying closely behind costal margin and meeting margin before apex of wing, often near or even before the midpoint. R1 and Rs typically short, with Rs branching into R2+3, and R4+5; R2+3 running forward and rejoining R1 to form cell r1 (usually termed first radial cell); R4+5 meeting C farther out to form cell r2+3; one or both of these cells sometimes lost either by closure (approximation of upper and lower veins) or by becoming confluent through loss of R2+3. Strong and characteristic crossvein r-m present. Posterior veins relatively weak; M2 sometimes incomplete basally or absent; crossvein m-cu absent; cubital fork well-developed; CuP and A weak, not reaching wing margin. Legs moderately long; claws usually similar, average in size; male with small claws that are usually bifid at tips. Abdomen l0-segmented; spiracles present on segments 2–7; segment 1 somewhat reduced; tergites 1 and 2 sometimes fused. Sternite 8 in female with slightly bilobate hind margin extending below opening of spermathecal duct; segment 9 with small tergite fused laterally to narrow band-like sternite, sternite usually dividing in midline around spermathecal opening; segment l0 small; cercus rounded, on small dorsolateral basal plate. Segment 8 in male with normal tergite and sternite; tergite 9 usually enlarged and prolonged backward to cover other elements of terminalia; gonopod two-segmented, conspicuous; aedeagus extending back from sternite 9 and articulated laterally with base of gonocoxite, often triangular with sclerotized lateral arms or ventral plate; paired parameres usually present above aedeagus. Early stages usually found in moist or aquatic habitats; larva apneustic, often elongate in form, and a strong swimmer; head usually sclerotized; mandible strong, toothed, not apposed; pharyngeal apparatus conspicuous internally, with two strongly diverging arms and series of combs apparently serving to reduce and sort food; short collar between head and thorax; three thoracic and nine abdominal segments well-defined; no functional spiracles.
