Lepechinella monocuspidata J. L. Barnard

Lepechinella monocuspidata J. L. Barnard, 1961:99, fig. 68.

DIAGNOSIS.–Length of dorsal teeth and coxae of medium size relative to most extreme species of genus, dorsal teeth about two-thirds length of coxa 2, pereonite 1 with one middorsal tooth, pereonite 2 to pleonite 4 with one tooth, no accessory teeth; body naked; epimera 1–3 nearly straight posteriorly, epimeron 1 with softly rounded posteroventral corner, epimera 2–3 with weak sinus and small sharp tooth, epimeron 2 lacking lateral setae; rostrum thin, extending less than half way along article 1 of antenna 1, first cephalic tooth as long as rostrum, second tooth slightly shorter; mandibular palp unknown; coxa 1 deeply serrate, indistinctly bifid, otherwise slipper-shaped, coxa 2 posteroventrally serrate but not bifid, coxae 3–4 weakly bifid, coxa 3 asymmetrically, coxa 4 symmetrically, coxa 5 with anterior limb as long as coxa 4, coxa 6 with weakly rounded anterior lobe, bluntly extended posteroventrally, coxa 7 with small sharp, curved posteroventral tooth; accessory flagellum uniarticulate, length unknown; telson deft halfway, lobes scarcely gaping, much like that of Atylus, each lobe with one long apical setal spine; outer ramus of uropod 1 unusually thick, length of inner ramus unknown; uropod 2 very small, rami extending equally; uropod 3 ordinary.

REMARKS.–Probably the view of coxa 2 shown by J. L. Barnard (1961, fig. 68A) on the whole animal is erroneous; a correct view is in figure 68c of the same publication.

DISTRIBUTION.–East Africa, 1510 m.
