Identification key to the Cyrtopogon-species

back to the key to Stenopogoninae

In Germany, the most common of the three known species is Cyrtopogon lateralis, which is even distributed in the northern lowlands. The other species are restricted to boreo-montane areas in the Holarctic Region and, like most species of Lasiopogon, represent an ecologically distinct group within Asilidae.

Cyrtopogon lapponicus (Zetterstedt, [1838]) from Scandinavia is lacking in this key.

1 a.	Legs black [Fig. 1]; males: tergites 2 and 3 covered with white tomentum [Fig. 2] . . . . . . . . . . . . Cyrtopogon lateralis (Fallén, 1814)

1 b.	Tibiae at least in part red [Fig. 3], [Fig. 4]; not a single tergite completely covered with whitish tomentum . . . . . . . . . . . . to 2

2 a.	Postpedicel black [Fig. 5]; tergites with white hairs only laterally; males: tarsomeres (tarsi) of front leg of usual shape [Fig. 6] . . . . . . . . . . . . Cyrtopogon maculipennis (Macquart, 1834)

2 b.	Postpedicel red [Fig. 7]; tergites 2-4 nearly completely covered with densely arranged yellow hairs; males: tarsomeres (tarsi) of front leg distinctly elongated [Fig. 8] . . . . . . . . . . . . Cyrtopogon ruficornis (Fabricius, 1794)
