Trichophallus Salomona Group

The following species of the Salomona Group are very similar in general appearance, as well as in the shape of the male tenth abdominal tergite that is provided with a long apical incision and the subgenital plate terminates into a pair of long apical lobes; also the titillators are very similar within this group. The species differ in the arrangement, size and shape of the pair of internal teeth of the male cerci as well as in length and curvature of the cerci and the exact position of the internal tooth. Conspicuous are differences in number and density of the teeth on the stridulatory file. Thus there might be differences in the acoustic behaviour between the species. Females of the group, so far known, have widened apical lobes of the subgenital plate that differ somewhat between species.
