Description
Key to males of West-Palaearctic Dasydorylas Skevington, 2001
For generic identification, follow the key in Kehlmaier (2005a) to couplet 18.
1 Abdominal tergites densely covered with rather long bristly hairs (♂♂: up to 0.07 mm). (Dorso-) lateral fan of tergite 1 with about 13 strong, dark bristles of different length. Male genitalia as in Kehlmaier 2005a: fig. 15a–h .................................................................... D. horridus (Becker, 1897)
– Abdominal tergites less densely covered with shorter hairs (up to 0.05 mm). (Dorso-) lateral fan of tergite 1 with about 8 bristles at the most.....................................................................................2
2 Flagellum extremely long tapering, filiform (LF:WF>5.5) (Kehlmaier 2005a: fig. l8i). Syntergosternite 8 without membranous area. Eyes meeting for about ten times diameter of ocellus. F:EM= 1:0.5–0.6. LTC:LFC =0.6–0.8. Surstyli and genitalia as in Kehlmaier 2005a: fig. 18a–h ....... ............................................................................................................... D. filiformis Kehlmaier, 2005
– LF:WF<4.0. Syntergosternite 8 with membranous area. Eyes meeting for 15 to 20 times diameter of ocellus. F:EM=1:1.0–1.2. LTC:LFC>1.6.....................................................................................3
3 Scutellar hair fringe with 6 very strong bristles (up to 0.2 mm). Flagellum very long, tapering (LF:WF=3.7–3.9) ..................................................................................... D. setosus (Becker, 1908)
– Scutellar hair fringe with up to 14 shorter bristles (up to 0.07 mm). Flagellum shorter (LF:WF= 2–2.3).................................................................................................................................................4
4 Phallic guide with up to 14 long spines on each side, pointing upwards into different directions. Each surstylus distally with a single outward bent finger-like projection (Kehlmaier 2005b: fig. 12i) ........................................................................................................... D. gradus Kehlmaier, 2005
– Phallic guide with less than 10 long spines on each side...............................................................5
5 Phallic guide with 8 downwards directed long spines on each side. Each surstylus with a pair of finger-like projections which are bent towards each other (Fig. 3E) ......................................... ..................................................................... D. derafshani Motamedinia & Kehlmaier sp. nov.
– Phallic guide with only 2 spines on each side.................................................................................6
6 Gonopods with elongated regions of distinctly stronger sclerotization (Fig. 5A). Phallus short and length of ejaculatory ducts shorter than length of surstyli ......................................................... ............................................................................... D. zardouei Motamedinia & Kehlmaier sp. nov.
– Gonopods without elongated regions of stronger sclerotization. Ejaculatory ducts of phallus longer than surstyli.......................................................................................................................................7
7 Dorsolateral spines of phallic guide rather strong, situated at end of basal half (Kehlmaier 2005a: fig. 14a–b). Surstyli as in Kehlmaier 2005a: fig. 14d, j–k. Phallus with long ejaculatory ducts (Kehlmaier 2005a: fig. 14h). Membranous area occupies about half the width of syntergosternite 8 (Kehlmaier 2005a: fig. 14e) .............................................. D. holosericeus (Becker, 1897)
– Dorsolateral spines of phallic guide somewhat smaller and situated after basal third (Kehlmaier 2005a: fig. 16a–b). Surstyli as in Kehlmaier 2005a: fig. 16d, j–k. Phallus with shorter ejaculatory ducts (Kehlmaier 2005a: fig. 16h). Membranous area occupies about a third of the width of syntergosternite 8 (Kehlmaier 2005a: fig. 16f) ............................................................ D. roseri (Becker, 1897)
