Genus Asteropterygion Kornicker, 1981

 

Introduction

The largest genus in the subfamily Asteropteroninae, Asteropterygion is characterized by a carapace with processes, ridges and nodes, and the presence of the d- seta. Kornicker (1981) split eleven species from Asteropteron, and described three new, including the type species Asteropterygion thomassini Kornicker 1981. The genus is divided into two groups, based on whether the a-seta is claw-like or not. There are 15 species.

Diagnosis

Carapace with nodes, ridges and shallow oval fossae; anterior with distinct but usually relatively small incisure. First antenna: sensory bristle of 5th segment of female with 1–5 short proximal filaments and 4 to 6 or 7 long distal filaments, including stem. d- and e-bristles of 8th segment well developed. Sensory bristle of 5th segment of male generally with abundant filaments. Second antenna: protopod with medial bristle; female endopod 3-segmented. Mandibula: basale dorsal margin with 2–13 bristles in addition to terminal pair; ventral margin with 2 or more triaenid bristles and some not of triaenid type. Maxilla: basale with numerous bristles, exopod small. Fifth limb: dorsal margin of comb of both sexes evenly rounded without processes. Sixth limb: with 0–4 epipod bristles. Seventh limb: each ring with 2 bristles, 1 on each side. Furca: each lamella with 3 main claws followed by 3–10 secondary bristle-like claws.
