Hiekeianus Endrödi, 1978

The genus Hiekeianus contains only one very rare species from Paraguay, H. tuberculatus Endrödi, 1978 . Aside from the male holotype deposited at the Museum für Naturkunde in Berlin, I know of only three other specimens.

The single species in the genus is characterized by a reddish brown color; frons with a single tubercle; clypeus strongly contracted towards apex; mandibles exposed and evenly rounded; antenna 10-segmented with short club; pronotum simply convex; long prosternal process; quadridentate protibia; and metatibia at apex with spinules. The biology of H. tuberculatus is unknown.

Distribution. Stenocrates caiporae is known only from the village of Estirão do Equador that is situated on the Rio Yavari on the border of Brazil’ s Amazonas state with Peru.

Temporal Distribution. November (2).

Diagnosis. The form of the parameres is a necessary distinguishing character in Stenocrates species since their external body morphology is usually so similar. Accordingly, S. caiporae is not here incorporated into Endrödi’ s (1985) key. The parameres of S. caiporae are remarkably similar to those of Stenocrates haackae Ratcliffe ( Figs. 9–10 ), which was described from central Amazonian Brazil. But there the similarities end. Stenocrates caiporae and S. haackae are compared in Table 1.

Natural History. As is the case with most other species of Stenocrates , nothing is known of the life history of S. caiporae .
