(IBSP 636); BRAZIL, Pará: Aurá (01°26’37.99”S; 48°23’9.24”W), 2♂, 6♀, ♀ immature, 18.IV.1940, A. L. Carvalho leg.

 Diagnosis. Males of H. cayennophilus can be recognized by a rounded process on the prefemur of the first pair of legs (Fig. 43). Gonopod with an erect straight proplica (Fig. 36); a short or inconspicuous (MAURIÈS, 1975:1273, figs 32, 33) apicomesal process (app, Figs 36, 37); distolateral process on metaplica (dmp, Figs 36, 37) not protruding in posterior view; contiguous with metaplica (Fig. 37), different in diagonal aspect from that of H. bidens (Fig. 34); short and rounded in appearance.   
 Description. Described by SCHUBART (1947) as O. brasiliensis and with a complementary description by MAURIÉS (1975). Additional data are presented here.   
Male (IBSP 636) (Figs 30-32). Total length: 40 mm. Maximum vertical diameter: 2 mm.  
First pair of legs: coxae rounded, with 5+5 setiform setae in a curved row on mesal region (Figs 42, 43). Prefemur triangular; 2+2 distomesal setae; a rounded prefemoral process; inconspicuous scattered setae at base of the process (Fig. 43). Tibia with membranous ventral pads (Fig. 42). Neither femur nor postfemur with ventral pads (at least not imperceptible). Second pair of legs: coxae rounded. Prefemur apprised to and contiguous with distal portions of the coxae; postfemur and tibia with very short membranous ventral pads (Fig. 44). Penis elongated and rounded.  
Gonopod (Figs 36−38). Sternum semi-circular. Paracoxite (px) rounded. Proplica very short (pp); erect straight; with short apico-mesal process (app, Fig. 37). Metaplica elongated (mp); distolateral metaplical (dmp) process not protruding in posterior view (Fig. 37), rounded and contiguous with metaplica. Inner process of metaplica (ip) evident; straight (Fig. 38). Telopodite bulky; antetorsal process absent; a large, lamellar, broad expansion covering partially the solenomere. Solenomere with one complete 360° torsion.  
Distribution. Known from the northern region in French Guiana (SILVESTRI, 1897b; MAURIÈS, 1975), and extending down to the state of Pará in Brazil (SCHUBART, 1947).
