Gonatopus groups Gonatopus females were divided for convenience by Olmi and Virla (2014) into 12 groups. They are distinguished on the basis of the following characters: 1 Fully winged.................................................................................. Group 11 - Apterous........................................................................................... 2 2 Enlarged claw without subapical tooth (Fig. 9 in Olmi 1994b), or with one very small subapical tooth (Plate 181A in Olmi & Virla 2014)......................................................................................... 3 - Enlarged claw with one large subapical tooth (Plate 168D, E in Olmi & Virla 2014)............................... 6 3 Distal apex of enlarged claw with group of lamellae (Fig. 9 in Olmi 1994b)................................ Group 8 - Distal apex of enlarged claw without lamellae (Plates 181A, E, 182E-G, 183C, D in Olmi & Virla 2014 ................ 4 4 Pronotum crossed by strong transverse furrow (Plates 181C, D, 182A-D, 183A, B in Olmi & Virla 2014)......... Group 7 - Pronotum not crossed by transverse furrow or slightly impressed (Plates 202, 203A, C in Olmi & Virla 2014)........... 5 5 Palpal formula 6/3.............................................................................. Group 12 - Palpal formula different.......................................................................... Group 6 6 Pronotum not crossed by transverse furrow or slightly impressed (as in plate 172B in Olmi & Virla 2014 ................ 7 - Pronotum crossed by strong transverse furrow (Plates 164C, 167E in Olmi & Virla 2014).......................... 8 7 Labial palpi 3-segmented......................................................................... Group 9 - Labial palpi 2-segmented......................................................................... Group 5 8 Enlarged claw without lamellae, with or without bristles or peg-like hairs (Plate 153B, D in Olmi & Virla 2014)... Group 1 - Enlarged claw with lamellae (Plates 154E, F, 155 D, E in Olmi & Virla 2014)..................................... 9 9 Labial palpus 2-segmented............................................................................. 10 - Labial palpus 3-segmented............................................................................ 11 10 Maxillary palpus composed of 2–4 segments......................................................... Group 2 - Maxillary palpus 5-segmented.................................................................... Group 10 11 Maxillary palpus 6-segmented..................................................................... Group 4 - Maxillary palpus with 4–5 segments.................................................................... 12 12 Maxillary palpus 5-segmented..................................................................... Group 3 - Maxillary palpus 4-segmented................................................................... Group 10 The above groups are distributed in the zoogeographical regions as follows: Palaearctic: groups 1, 2, 3, 4, 5, 6, 7, 10, 11. Afrotropical: groups 1, 2, 3, 4, 5, 6, 7, 8, 11. Oriental: groups 1, 2, 3, 4, 5, 6, 7, 10. Nearctic: groups 1, 2, 3, 4, 5, 6, 7, 9, 10, 12. Neotropical: groups 1, 2, 3, 4, 5, 6, 7, 10, 12. Australian: groups 1, 2, 4, 5, 6, 7, 9. As far as, it is not possible divide also males into groups.
