| Abstract |
The superfamily Erythrosquilloidea is erected for the family Erythrosquillidae, which contains one genus and species, Erythrosquilla megalops Manning & Bruce, 1984. This new superfamily differs from the Bathysquilloidea, Gonodactyloidea, and Squilloidea by its member having broad and ventrally beaded propodi of the third and fourth maxillipeds; it differs from the Lysiosquilloidea by having a distinct dorsal median carina on the telson. The superfamily may represent a relict lineage within the Stomatopoda. The family Tetrasquillidae is erected in the superfamily Lysiosquilloidea for three genera, the monotypic Tetrasquilla Manning & Chace, 1990; Tectasquilla Adkison & Hopkins, 1984; and Heterosquillopsis Moosa, 1991, which contains three species. This new family can be distinguished from the three families now remaining in the Lysiosquilloidea by its members having ovate rather than styliform (as in the Lysiosquillidae) distal segments of the endopods of the first two walking legs, by lacking an enlarged basal lobe on the dactylus of the claw (Coronididae), and by lacking a strong proximal fold on the outer margin of the uropodal endopod (Nannosquillidae). The only known pantropical stomatopod. Tetrasquilla mccullochae (Schmitt, 1940), is included in this family. |
