Remarks

Brindle (1968f: 246) considered T. jacobsoni to be a lighter form of T. bicuspis (Stål, 1860) ; however, Steinmann (1982b) presents T. jacobsoni as a species in its own right. In the original description, Borelli referred to 4 specimens examined: 1 ♂ with data as F3233.1870, and 2 ♂♂ and 1 ♀ with data as F3233.1869 except the date 1924. He did not designate a holotype and it appears therefore that all four specimens should be considered syntypes. According to Steinmann (1982b: 365), 1 ♂ was held at Museo ed Istituto di Zoologia Sistematoca, Torino, which Steinmann appears to have designated the holotype (‘without penis’, although the male genitalia are figured in Steinmann’s description).
