Diagnosis and Specialized Morphology
Salyavatinae are sometimes referred to as termite-feeding assassin bugs. Most members of this subfamily are characterized by:
1) small, somewhat globular head that is constricted behind compound eyes
2) sometimes antennae appear 3-segments and inserted on prominent, anteriorly projecting tubercules
3) moderately long and weakly curving labium
4) sharp, slender spines on pronotum, scutellum, and abdomen
5) fossula spongiosa present on fore and middle legs
6) foretarsi 2-segmented and 3-segment on other legs
Taxonomic history for this subfamily is being reviewed.
Salyavatinae is comprised of 16 circumtropical genera (Schuh & Slater 1995). Most species are nocturnal. In some species, nymphs possess sticky setae that is utilized in camouflaging with debris (Schuh & Slater 1995).
