Comment: Characters used for determination include two postrostral teeth separated from the rostral group and eye diameter about 22% carapace length (Roberts & Pequegnat, 1970: 29, key). This species has a long flagelliform P5, illustrated in Perez Farfante & Kensley (1997: 171, fig. 118) that is missing on specimens photographed. Hymenopenaeus debilis ressembles Hymenopenaeus aphoticus Burkenroad, 1936 also in the region but is distinct by 1-2 distal spines present on disto-ventral margin of rostrum.
