The T. tricolor species-group

Diagnosis. Species of the species-group are externally similar to the T. protuberans and T. differens species-groups but their male genitalia differ in the phallus bearing a carinal process. Additionally,

compared to the T. protuberans species-group, the male genitalia of the T. tricolor species-group have a shorter vinculum with thin bunch-shaped caselli (vs. thick saccate ones in the T. protuberans species-group), a longer distal saccular process, and a smaller phallus (in proportion to the genital capsule). The female genitalia of the species-group are characterised by the corpus bursae clearly subdivided into the posterior and anterior sections by the medial constriction: the posterior section of the corpus bursae is heavily gelatinous with areas of sclerotisation while the anterior section is globular and membranous. The appendix bursae structure is diagnostic: in the T. tricolor species-group it is clavate with a proximally sclerotised and rugose proximal and a membranous dilated distal sections, whereas in other species-groups the appendix bursae is conical and membranous or gelatinous. Additionally, the 7 th abdominal sternite of the species-group has short rounded subostial lobes (also found only in T. sayinyingpo sp n. of the T. protuberans species-group).
