Identification key to the species of the Neomochtherus-group

back to the key to Asilinae start of the key

This genus is distributed in the southern and eastern Palaearctic Region and only two species are known from Germany. TSACAS (1968) placed the western Palaearctic species in species-groups and LEHR (1996) subsequently erected new genera for these. The genera are primarily diagnosed by characters of the male terminalia. However, there are intermediate forms known and therefore it is questionable if Tsacas' species-groups or Lehr's genera are monophyletic and the present classification is unsatisfactory. LEHR also synonymised Paritamus with Neomochtherus. Aneomochtherus is recognised in the identification key because it is possible to confuse this taxon with Neomochtherus. Most of the species of the Neomochtherus-group have pale legs, a small facial gibbosity with only few bristles forming the mystax, and distinctly broadened hypopygia.
A table for comparison of taxa is provided on this CD-ROM.
