Tribe TRICHOPODINI 
The Trichopodini are primarily a tropical and subtropical group and are best 
represented in the Neotropics, but a few members of the tribe occur in the Ethiopian 
Region, in the south-east Asian islands, in Melanesia, and in Queensland and New 
South Wales. In Australia two genera occur, Savalba which is an endemic Austra- 
lasian genus found from New South Wales to New Guinea, and Pentatomophaga 
which is an essentially Afro-Oriental element in the Australian fauna and occurs 
from Java to Queensland and New Caledonia. The African connection is shown 
clearly by the fact that Pentatomophaga (although here accepted as valid, pending 
revision of the Old World Trichopodini by a specialist on Phasiinae) is not really 
distinct from the African trichopodine genus Bogosia Rondani (cf., for example, 
Pentatomophaga bicincta de Meijere and Bogosia minor Villeneuve). 
The chief characteristics of the Trichopodini are as follows. Head dichoptic, interfrontal 
area wide in both sexes, eye facets not enlarged; 9 without proclinate orbital setae; face 
without a median keel; ocellar setae proclinate (often very weak); antennae moderately or 
very short (not nearly reaching epistome); palpi present; humeral callus with one or two 
setae; ph setae nil or one; acy setae usually 0 + 1; dc setae variable, commonly I +4 2, 
sometimes more; pra seta present or absent (usually absent); one sa seta; one post ia seta; 
o+1or1+1 sétpl setae; infrasquamal hairs present (usually minute); scutellum with two 
pairs of marginal setae, without discal setae; wings rather long and usually narrow, not 
normally sexually dimorphic; second costal sector haired ventrally; basal node of R,,; bare 
or with one or two very minute hairs; bend of vein M forming an open rounded obtuse curve; 
cell R; open or just closed at the wing margin or with a very short petiole (less than the length 
of y-m); wing membrane partially or wholly infuscate; last section of Cu, very short (less 
than half as long as m-—cu); lower calypter very broad posteriorly and with outer posterior 
corner rather produced, hind margin straight or slightly concave; legs weakly bristled, tibiae 
not very strongly curved, hind tibia in many New World forms armed with a long fringe 
of flattened black scales; hind tibia without a pd preapical seta and without pv apical seta; 
hind coxae rather widely separated from abdominal base, but posteroventral declivity of 
the thorax incompletely sclerotized (membranous or semi-membranous medially); abdomen 
elongate and dorsoventrally flattened in most forms, sometimes slightly clavate; Ti + 2 
excavate only at extreme base (virtually without any excavation); abdominal bristling very 
weak, sometimes no definite setae developed (vestiture all hair like); short flattened T6 visible 
from above in both sexes (usually armed with some short stubby setae on the posterior part); 
© postabdomen not recurved, ovipositor very short and inconspicuous. 
In both the Australian genera of Trichopodini the thoracic and leg colour is 
similar: the mesonotum is velvety black or brownish black with two transverse 
golden or golden-orange bands (one on the posterior half of the prescutum connecting 
the notopleura and the other on the scutum immediately before the scutellum); 
and the legs are yellow or orange basally (as far as the basal parts of the femora) 
and black on the remainder. The head form is shown for Savalba in Text-fig. 26.
