Genitalia, Figs 20 A–C. Symmetrical. FEMALE. Unknown. Type material. HOLOTYPE . ♂, N.E. Burma , Kambaiti, 7000 ft ., 5.v.1934 , R. Malaise ( BMNH ). Etymology. The name is Latin, mirifica , causing wonder, referring to the extraordinary cross vein between R1 and R2+3. Discussion. Sphegina mirifica is similar to S. forficata and S. crucivena . In addition to the characters mentioned in the key it differs by the following characters in the male genitalia: 1) surstylus is more strongly curved and broad (not attenuated) at the apex, 2) aedeagal lobe is angulate (not smoothly curved) and 3) the ejaculatory hood is very short (long). The superior lobe is large and long as in S. crucivena , but straight (not angularly curved).
