Imago (
Fig. 56
). Labial palpus with third segment as long as second. Clypeus with ventral margin broadly truncate or rounded. Antenna longer than half forewing length. Ocellus absent. Posterior area of sitophore with four campaniform sensilla not in trapezoid; anterior area with two or four campaniform sensilla. Forewing (length/width ratio 4.6) with pterostigma; R5 and M1 stalked, M2 and M3 connate, CuA1 and CuA2 present (

Fig. 16
).
Male genitalia (

Diagnosis.
Sinoe
species
are superficially similar to
Coleotechnites
, but can be differentiated by having the forewing with the subbasal fascia directed from apex of costa toward posterior margin, and by the bilaterally symmetrical vinculum + valva and apically hook shaped ventral gnathos instead of a cushionlike apex in male genitalia.
