Members of this group, Etmopterus pusillus (Lowe, 1839) and Etmopterus bigelowi Shirai and Tachikawa, 1993, also possess a lateral line that ends in an open groove, suprapelvic flank markings lacking a posterior branch, and a relatively cylindrical body (Shirai & Tachikawa 1993).
The wing venation nomenclature used in this paper is based on the interpretation of Bethoux & Nel (2001, 2002): C, costa; ScA, anterior subcosta; ScP, posterior subcosta; RA, anterior radial; RP, posterior radial; MA, anterior media; MP, posterior media; CuA, anterior cubitus; CuPa[alpha], the anterior branch of first posterior cubitus; CuPa[beta], the posterior branch of first posterior cubitus; CuPb, the second posterior cubitus.
They are repeated for convenience: RA, anterior Radius; RP, posterior Radius; RP1, RP2, branches of RP resulting from the fork of the anterior branch of RP; RP3, RP4, branches of RP resulting from the fork of the posterior branch of RP; IR1, IR2, intercalary pseudo-veins between RP1 and RP2, and RP2 and RP3, respectively; MA, anterior Media; MP, posterior Media; CuA, anterior Cubitus; CuP, posterior Cubitus.
