Juppius Group  

Species of the Juppius Group are characterised and distinguished from other species of subgenus Ochlerotatus by the following combinations of characters. Characters that diagnose the Juppius Group (as subgenus Juppius) in the phylogenetic analyses of Reinert et al. (2009), based on features observed in Ae. caballus, are indicated by an asterisk (*).

MALE GENITALIA – Gonocoxite with apical mesal lobe and small basal mesal lobe each bearing few setae, ventral surface with several broad scales on lateral and ventral surfaces, mesal surface membranous; gonostylus attached at apex of gonocoxite, long, approximately 0.70 length of gonocoxite, gonostylar claw attached at apex; claspette comprised of short columnar stem bearing *1 flattened apical spiniform (claspette filament), *stem ≤ 0.85 length of aedeagus; aedeagus tube-like, lateral margins bowed outward, widest in middle third; cercal setae present. LARVAE – *Antenna ≤ 0.40 length of dorsal apotome, with few minute spicules; seta 1-A with 1–3 branches, *length ≤ 3.0 diameter of antenna at point of attachment; seta 4-C single or double, inserted mesal and in line with seta 6-C; setae 5,6-C single, *both 0.21–0.38 length of dorsal apotome, 5-C inserted posteromesal to setae 6,7-C, setae 6-C inserted mesal and slightly posterior to seta 7-C; seta 12-C inserted mesal to seta 13-C; seta 13-C single, longer than seta 12-C; seta 14-C single; seta 19-C absent; setae 1–3-P not inserted on common setal support plate, setae 1,2-P single, seta 3-P short, with 2 or 3 branches; seta 4-P short, single or double; seta 6-P normally double (rarely single); *seta 8-P multi-branched; seta 7-I with 2 or 3 branches, approximately 0.60 length of seta 6-I; seta 12-I present; seta 6-II–IV double, 6-II longer than 6-III; *seta 1-VII ≤ 0.42 mid-dorsal length of segment X; comb with several thorn-like scales in curved row; siphon relatively short, pecten with several evenly spaced spines on proximal 0.45; seta 1-S inserted distal to pecten; saddle of segment X incomplete ventrally, acus present; seta 1-S single, inserted on saddle; ventral brush (seta 4-X) with 2 (rarely 3) precratal setae and numerous setae inserted on grid with well-developed transverse and lateral bars.
