First and third instar larvae of Aepopsis robini (Laboulbene, 1849) are stu
died, redescribed, and illustrated. The larvae are characterised by three u
nique and likely autapomorphic character states within known members of the
supertribe Trechitae: (1) apex of antennomere 4 has only one conical sensi
llun 1; (2) setae FR10 and FR11 on frontale are removed basally on dorsal s
urface from the apical margin; (3) terga of meso- and metathorax lack pore
MEa, and abdominal terga 1-8 lack pore TEa.
