Definition. Penis lobes moderately long and moderately widened apically, with narrow lateral pouches; telopenes in form of spear-like rolls, attached on dorsal side and directed medially-dorsally ( Figs 143–145 , 169, 171 ) (the same in many other species). In imago and subimago of both sexes, femora with one multicolored apical band ( Figs 160–161 ); in male, abdominal terga II–VI whitish, terga VII–X orange ( Figs 136 , 166 ) (the same coloration of legs and male abdomen in many other species).

Composition. Among species described here, Th. panamensis sp. n. and Th. viviparus sp. n.
