Key to the males of Psilota View in CoL from the Palaearctic Region
This key is mainly based on Smit & Vujić (2008) and Radenković et al. (2020).
1 Face at most only slightly microtrichose, clearly shiny face below the antenna. Thorax and abdomen (bluish) black colored.................................................................................. 2 ( P. atra View in CoL species-group)
- Face heavily microtrichose, clearly dull beneath antennae. Thorax and abdomen more bronze-colored................................................................................................ 7 ( P. innupta View in CoL species-group)
2 Epandrium in lateral view longer than broad............................................................... 3
- Epandrium in lateral view as long as broad, or broader than long............................................... 5
3 Metafemur not swollen and with a shallow groove apicoventrally, formed by two rows of mixed short and long black pines. Basoflagellomere about 2 times longer than broad. Epandrium in lateral view 1.2 times longer than broad (see figure 11A in Radenković et al., 2020)..................................................................... Psilota aegeae View in CoL
- Metafemur swollen................................................................................... 4
4 Metafemur slightly swollen, without a spinose ridge. Epandrium in lateral view almost 1.5 times longer than wide (see figure 13 in Smit & Vujić, 2008).................................................................. Psilota kroshka View in CoL
- Metafemur clearly swollen and with spinose ridge apicoventrally. Epandrium in lateral view almost 2 twice longer than wide (see figures 11B, D in Radenković et al., 2020)..................................................... Psilota atra View in CoL
5 Epandrium about as long as wide in lateral view (see figure 15 in Smit & Vujić, 2008). Face only 1.7 times longer than frons. Basoflagellomere only little longer than wide, face and frons predominantly light haired, some black ones beside and just above the antenna................................................................................. Psilota nana View in CoL
- Epandrium broader than long in lateral view................................................................ 6
6 Surstylus very long and slender. Inner lobe about twice as long as the maximum length of the epandrium. Outer lobe extremely narrow, often not curved but folded backwards (see figure 8 in Smit & Vujić, 2008)................... Psilota exilistyla View in CoL
- Surstylus less long and slender. Inner lobe at most 1.5 times as long as the maximum length of the epandrium, outer lobe wider, curved down at the end, rarely a little backwards (see figure 4 in Smit & Vujić, 2008)................ Psilota anthracina View in CoL
7 Wing, though faint, clearly infuscate in the middle. Metafemur not swollen but with a spinose ridge apicoventrally........ 8
- Wing entirely hyaline without a faint cloud. Metafemur not swollen and without a spinose ridge; pleura entirely shining. Outer lobe bent or curved downwards at the middle (see figures 9–12 in Smit & Vujić, 2008).................. Psilota innupta View in CoL
8 Epandrium in lateral view almost 1.4 times longer than wider (see figure 17 in Smit & Vujić, 2008). Pleura lightly dusted. Basoflagellomere more than 2.5 times as long as wide.......................................... Psilota nigripilosa View in CoL
- Epandrium in lateral view as long as broad, or broader than long.............................................… 9
9 Epandrium in lateral view almost 1.12 times wider than long (fig. 11). Pleura entirely shining. Basoflagellomere approximately 1.8 times as long as wide...................................................... … Psilota bashanensis View in CoL sp. nov.
- Epandrium in lateral view as long as wide (see figure 6 in Smit & Vujić, 2008). Pleura slightly dusted. Basoflagellomere approximately 1.5 times as long as wide....................................................... Psilota brevicornis View in CoL
