boscis to exceeding it by the length of the 
terminal segment; usually similar to Ochlero- 
tatus in type but may be simple, straight, and 
with only a few hairs (at apices of segments 
III-V). Vertex dorsum and scutellum narrow- 
or broad-scaled, or with intermediate con- 
ditions occurring. Paratergite with or without 
scales. No lower mesepimeral bristles. Fore 
and mid tarsal claws toothed in both sexes, in 
the male the larger claws usually bidentate; 
hind claws simple in both sexes. Terminalia: 
Basistyle with apical lobe absent; basal lobe 
usually absent but occasionally weakly 
formed, or rarely even distinct iharperi). 
Dististyle appendage apical. Mesosome sim- 
ple. Claspettes present (with a peculiar baso- 
tergal lobe in aureostriatus) , with a prominent, 
variously shaped filament. 
LARVA: Extremely varied, but having in 
common the following few characteristics: 
Siphon almost always with an acus at level of 
pecten teeth. Anal plate without acus, always 
incomplete, nearly always with spines or 
spicules on posterior lateral margin. Ventral 
brush with 8-12 tufts, usually borne on a 
sclerotized, barred area. Habitat primarily of 
three types: (1) the water-holding spaces of 
living plants, (2) tree holes and bamboo 
stumps, and (3) rock holes in stream beds. 
One species breeds in the water collected in 
fallen leaves. A number of species have been 
occasionally found in artificial containers. 
DISTRIBUTION: This is a very large sub- 
genus with approximately 165 named species 
and subspecies and having a worldwide dis- 
tribution (absent from the northern rim of 
the Holarctic Region, however). The sub- 
genus has attained its greatest development 
in the Oriental Region. Twenty-five named 
species are at present known from the Philip- 
pines. 
SYSTEMATICS: On the basis of adult orna- 
mentation characters, this subgenus was 
divided into eight groups by Edwards (1932: 
148). Knight and Marks (in press) modified 
this system by combining two of the groups 
and by creating subgroups. Except for 
Group C, which is confined to the Ethiopian 
Region, all the groups are represented in the 
Philippines. 
Group A {kochi-giou^). Wings profusely 
spotted with areas of pale and dark scaling. 
Represented in the Philippines by ananae^ 
poicilius, stonei, medleri^ croceus, flavipennis, and 
luteus. 
Group B iterrens-gtovip) . Hind tarsi with 
basal and apical white bands on I, a narrow 
basal band on II, remainder dark. Repre- 
sented in the Philippines by melanopterus . 
Group D {aureostriatus- gto\x^) . Scutal mark- 
ing pattern consisting of 3-5 narrow longi- 
tudinal pale lines. Femora and tibiae not 
lined anteriorly for nearly their whole length. 
Represented in the Philippines by aureo- 
striatus^ saxicola, ahadsantosi, hurgosi, rizali, 
sherki, and jugraensis. 
Group E {mediovittatus-gsoug)) . Similar to 
Group D except that at least the mid femora 
and usually also one or more of the tibiae are 
lined anteriorly with pale scales for nearly 
their whole length. Represented in the 
Philippines by hanksi. 
Group F {alboannulatus-gtou.ip) . Scutal pale 
scale pattern not consisting of a set of longi- 
tudinal lines. Hind tarsi with basal bands on 
at least the first three segments. Represented 
in the Philippines by harperi. 
Group H {geniculatus-gsou^) . Tarsi all dark. 
Represented in the Philippines by saperoi, 
lacteus, laoagensis, niveus^ paradissimilis, leuco- 
pleurus, luzonensis, and leucomeres.
