Subgenus Oculeomyia Theobald, 1907

ADULTS – Rather large mosquitoes; maxillary palpus of females comprised of 3 palpomeres, palpus of males with 5 palpomeres, longer than proboscis, palpomere 3 with numerous setae, apex of palpomere 5 with pale scales and setae; proboscis with median pale band, proboscis of males with prominent median ventral tuft of setae; anterior two-thirds of scutum usually covered mainly with pale scales; ante- and postpronota with some narrow scales; postspiracular and prealar areas without scales; lower mesepimeral setae absent; wing completely dark-scaled or lightly to heavily speckled with pale scales; anterior surface of femora and tibiae varying from lightly to heavily speckled with pale scales or completely dark-scaled; tarsomeres with basal and apical pale bands; abdominal terga with basal or apical pale bands or both, sometimes completely dark-scaled. MALE GENITALIA – Tergum IX lobes not produced, with relatively few setae in row; subapical lobe undivided, usually without foliform seta; gonostylus simple, sickle-shaped; inner division of phallosome simple or complex, with or without cluster of finger- or teeth-like processes, sometimes with a subapical lobe bearing 2–4 foliform processes; outer division of phallosome simple and broad, leaf-like or with distinct median, lateral and sternal spines, sometimes largely reduced or not developed; basal sternal process of paraproct varied from short, slender and pale to very long, thick and dark, crown composed of numerous spine-like spicules and a few blades; cercal setae present. LARVAE – Head relatively smaller than other larvae of Culicini; antenna shorter than head, seta 1-A inserted at mid-length; median labral plate not distinguished, completely fused with dorsal apotome (distinction from all other genera of Culicini); maxilla, short and broad, maxillary palpus more than twice as long and partially fused with maxillary body, hypostomal sclerite fused with cranium; dorsomentum acutely triangular with denticulate or minutely serrated edges; seta 3-P developed similar to setae 1,2-P; seta 7-I similar to seta 6-I, 7-II small like seta 7-III–VI; setae 2,4-VIII with 2–7 branches; comb varied, scales usually large, spine-like, few in number; siphon very long and slender, pecten reduced to a few small spines; seta 1-S comprised of 2.5–6 pairs of posterolateral elements; saddle complete; seta 1-X short, branched; seta 2-X branched; seta 3-X single; ventral brush (seta 4-X) comprised of 5 or 6 pairs of setae on grid. PUPAE – Trumpet asymmetrically funnel-shaped, pinna with wide opening; setae of cephalothorax except setae 10,11-CT very short; seta 1-II usually single to triple or at most 5-branched; seta 2-II inserted anterolateral to seta 3-II, seta 2-III–VI usually inserted mesad of seta 1 and close to posterior margin of tergum, seta 2-VII variable in position, often inserted mesad of seta 1; seta 6-III‒VI normally single, more or less straight and rigid; seta 9-VIII inserted on sternum, removed from lateral and posterior margins of segment, distinctly shorter than sternum; caudolateral angle of segment acutely produced; paddle varied in pigmentation, outer part wider than inner part, margin practically smooth; seta 1-Pa present, rarely absent, seta 2-Pa present.
