Pronotum ( Figs. 11 A–B) about 1.2 times wider than long, with rounded granules on pronotal disc; with yellowish and very short setae distributed over pronotum. Elytra ( Figs. 11 A–B) about 1.3 times longer than wide, rounded granules distributed from base to apical callus, smaller granules in apical region; yellowish and very short setae in basal and apical thirds of elytra, transverse band of yellowish or reddish brown scales distributed from middle of elytra to apical callus. Male genitalia. Median lobe of aedeagus ( Fig. 18I ) with rectangular apex, with elongate setae confined in center; aedeagal apodemes about 2.2 times longer than median lobe. Internal sac with tiny spicules and armed with trilobate sclerite ( Fig. 19H ). Tegmen ( Fig. 20H ). Manubrium about 1.9 times longer than dorsal lobes. Female genitalia ( Fig. 21H ). Coxites elongate, with short setae at apex; styli cylindrical, with dense and elongate setae at apex. Spermathecal duct very short inserted into posterior margin of bursa copulatrix. Spermathecal capsule ( Fig. 22H ) curved, collum elongate with roughness on inner margin, ramus non-prominent, cornu rounded at apex; spermathecal gland elongate.

Geographical distribution. This species occurs in Brazil ( Wibmer & O’Brien 1986) and here this distribution is expanded to the states of Rio de Janeiro, São Paulo, and Santa Catarina ( Fig. 23I ) .

Associated plants. Bondar (1943) recorded H. ochrifer attacks on seeds Annonacea in Bahia state.

Remarks. Heilus ochrifer differs from the other species mainly in the transverse band of yellowish scales and larger and rounded granules uniformly distributed on the elytra.
