than head and thorax, sometimes longer than body. Living exposed on plants, 
occasionally in curled leaves or underground on roots.

Tribe Lachnini Wilson 
Wilson, 1911b:51. 
Characters. Frontal tubercles lacking; antenna and body usually hairy; 
secondary sensoria circular; unguis much shorter than base of VI, or if not, 
stigma greatly elongated; stigma usually more or less elongate and radial sector 
straight (except Anoecina and Lachnina in part); cornicle mere rim, usually 
on broad hairy cone, rarely mere pore or not evident (in Tramina and 
Kulachnina); cauda always broader than long, appearing semilunar and 
rounded but really ending in upturned point; anal plate rounded, entire.

Subtribe Anoecina Baker 
Baker, 1920a:13. 
Characters. Antenna six-segmented, with long hairs and protruding sub- 
circular or oval sensoria. Fore wing with stigma short and broad; radial sector 
curved, arising some distance proximally to tip of stigma; media once-branched, 
not faint. Tarsi short and thick, Aphislike; tarsal I triangular in lateral view. 
Cornicle on shallow hairy cone. Rostrum with segment V indistinct, 1.e., fused 
with IV. Cauda semilunar. Gonopophyses none.*
