 anterior pair of dorsocentrals slightly more than twice distance between anterior and posterior 

 pairs. Anterior scutellars divergent, long, about twice the length of scutellum ; posterior 

 scutellars convergent, closely approximated, as long as scutellum. Only one prominent sterno- 

 pleural (posteroventral), the anterior one minute. Legs yellowish grey, slender ; fore femur 

 with a row of about ten short thick black bristles anteroventrally on distal half. Preapicals on 

 all legs, apicals prominent on mid leg. Wings hyaline, slender, iridescent ; R 2 +s straight ; 

 costa reaching M ; /? 4 + 6 ending at wing tip ; i? 4 + 5 and M apically divergent. C-index about 

 5-9 ; 4V-index about 07 ; 4C-index about 04 ; 5x-index about 0-4 ; Ac-index about o-8. 

 Ci-bristles two, C3-fringe on basal one-third. Halteres yellowish white. Abdominal tergites 

 black, bluish grey pollinose, slender. In $ each abdominal tergite with an anteromedian small 

 longitudinal, and a lateral triangular apically broadened, dark spot. 



Periphallic organs : Genital arch black, broad, narrowing below, lower distal margin with 

 short setae. Anal plate conical, black, hairy, separated from genital arch. Clasper (?) elongate, 

 black, apically bifurcated, without teeth. Phallic organs : Aedeagus brown, elongate, large,

 west shore, evergreen shrubs on sandy shore, c. 1,800', 9-17.xii.1961 (R.L.C.), 

 BMNH. 



Allotype $. Same data as holotype male. BMNH. 



Paratypes : 4 J, 4 $, same data as holotype ; 1$, Tumlingtar, bare rocky slope 

 above River Sabhaya, west bank, c. 1,900', 8-24.xii.1961 (R.L.C.), BMNH. 1 $, 

 1 $, same data as holotype, deposited at the Tokyo Metropolitan University. 



Resembles A. obscuripes de Meijere, 1911, (Java and Formosa) in wing venation, 

 but differs from it in its pale hind tibia and tarsi and unicolorous mesonotum.
