Material examined. PANAMA. Darién Province, Pacific drainage: male, holotype, USNM 54044, Cana, 24.v.1912, E.A. Goldmann.

Description of gonopod. Straight in mesiocaudal view, apex bent approximately 90° in laterocephalic direction. Marginal suture on mesial side, straight; marginal process rounded, not produced beyond caudal border of apex. Mesial process subtriangular, slightly downturned, its distal border rounded. Lateral process very poorly developed, with small lobe distally, not wider than lateral end of apex; lateral process with irregular border, nearly straight proximally, with few scattered, minute setae. Distocaudal ridge short, wide, subtriagular, weakly developed. Cephalic surface ending as wide, flat flange distally, forming distinct transversal sulcus between this flange and bent apex. Apex oblong, narrow; caudal border slightly convex, with small notch near lateral end. Field of apical spines moderately developed, directed towards laterocephalic side.

Holotype and type locality. Male, cw 26.4, cl 17.3, USNM 54044 (specimen not in good condition, mostly dismembered, abdomen detached and carapace partially detached from the body). Panama, Darién Province, Cana (Pacific drainage); according to Rodríguez (1994), Cana refers to Mount Cana, altitude 1615m, 07°48’N 77°32’W, Darién Province.

Distribution. The species is so far known only from the type locality, on the Pacific drainage, eastern Panama ( Fig. 81 ).

Remarks. Abele & Kim (1989) recorded two males from the former Panama Canal Zone, but they probably belong to P. cocleensis (see Remarks under that species).
