Remarks. Tyrannoseira raptora  differs from other congeners by its body colour being all blue/dark ( T. diabolica  and T. sex  are mostly pale), and having pigment also present on distal Ant II to IV, while T. bicolorcornuta  and T. gladiata  have a distinct pattern on the distal half of segments ( Fig. 1View FIGURE 1). The head of T. raptora  dorsally differs by having An 3i and An 3i 2 as mic (both absent in T. gladiata  and T. sex,  An 3i 2 absent in T. bicolorcornuta  and T. diabolica  ), and with 3 extra posterior mac (1 in T. diabolica  , 2 in other species). Tyrannoseira raptora  also has Ant III without subapical modified sens (type– f present in T. bicolorcornuta  and T. gladiata  ), a clypeus with l1 apically acuminate and l2 normal (both acuminate in T. bicolorcornuta  and l1 normal in T. sex  ), its outer labral papillae subequal to inner papillae (smaller in T. gladiata  and T. sex  , reduced in T. bicolorcornuta  ), and a head ventrally with 2 posterior postlabial chaetae below ‘J’ row (1 in T. bicolorcornuta  , 3 in T. diabolica  and T. gladiata  ). The body chaetotaxy of T. raptora  differs on Th II in lacking a4+, a 4i, m 1i, p1ip mac (mostly present in other species), Th III with a6 mac (as mic in T. bicolorcornuta  , T. gladiata  and T. sex  ), and Abd IV without A3a, B1, B2 and T7 mac (mostly present in other species). Other differences in chaetotaxy of T. raptora  are: trochanteral organ with 27–31 spine-like chaetae (fewer in other species), collophore with 3 anterior and 3 posterior spine-like chaetae (4 anterior and 1 posterior in T. diabolica  , 2 posterior in T. sex  ), and manubrium ventrally with 2/4 subapical chaetae (2/ 2 in T. bicolorcornuta  , 0/ 2 in T. diabolica  ). The differences between the species are listed in Table 1.
