description: Gonatopus groups
Gonatopus females were divided for convenience by Olmi and Virla (2014) into twelve groups. The above 12 groups 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 the above groups.
