DISTRIBUTION.—Lagotowia.

Harpiniopsis Stephensen

Harpiniopsis Stephensen, 1925:171.—J. L. Barnard, 1960:325.

DIAGNOSIS.—Eyes absent. Flagella of antennae 1–2 unreduced in female. Article 2 of antenna 1 especially shortened, ventral setae confined apically. Article 1 of antenna 2 not or weakly ensiform; article 3 with numerous setae and setules; facial spines on article 4 in one main row; article 5 ordinary in size to especially short. Right mandibular incisor with 3–4 teeth; molar not triturative, small, pillow-shaped, bearing 2 or more splayed, semi-articulate spines, usually not bearing fuzz; palpar hump small to medium. Palp of maxilla 1 biarticulate. Inner plate with 2 setae. Setation of maxilla 2 weak. Inner plate of maxillipeds ordinary, apex of palp article 3 not protuberant, dactyl short, stubby, apical nail distinct, elongate. Gnathopods ordinary, small, similar or gnathopod 2 weakly enlarged; article 5 of both gnathopods very short, almost cryptic on gnathopod 2, without eusirid attachment, palms oblique, hands ordinary, ovatorectangular, elongate, poorly setose anteriorly. Article 5 of pereopods 1–2 setose posteroproximally. Article 2 of pereopod 3 of narrow form, articles 4–5 of pereopods 3–4 narrow, article 2 of pereopods 3–4 not setose posteriorly; pereopod 5 ordinary, article 2 naked or weakly to strongly toothed ventrally, article 3 enlarged, dactyl normal. Epimera 1–2 lacking long posterior setae, without midfacial setae above ventral facial ridge; epimeron 3 ordinary or of rounded classification bearing fewer than 3 setae. Urosomite 1 generally naked; urosomite 3 without dorsal hook or special process. Peduncle of uropod 1 normally elongate, without apicoventral spike, without special enlarged apicolateral–medial spine, [?peduncular apices of uropods 1–2 not combed], inner ramus of uropod 1 with marginal spines in one row, no rami continuously spinose to apex, inner ramus of uropod 2 ordinary. Uropod 3 ordinary, elongate article 2 of outer ramus carrying 1–2 short to long to vestigial apical setae. Telson with 1–4 apical setae on each lobe plus setules, occasionally with special dorsal and lateral setae.

DESCRIPTION.—Rostrum fully developed, head often with anteroventral tooth. [Fuzz on article 1 of antenna 1 in male unknown; calceoli on male primary flagellum of antenna 1 unknown.] Calceoli on article 5 of male antenna 2 present; flagellum in male elongate, [?flagellum in male with calceoli]. Prebuccal parts ordinary to strongly extended forward, occasionally massive, strongly distinct or poorly separated from each other, dominance of either epistome or upper lip variable. Right lacinia mobilis bifid or simple, flabellate or thin; mandibular palp thin, article 1 short, article 2 without outer setae, apex of article 3 oblique. Lower lip bearing cones. Outer plate of maxilla 1 with 11 spines, one spine especially thickened. Inner plates of maxilliped poorly armed, thick. Coxae 2–4 without special anterodorsal humps. All posterior spines on article 6 of pereopods 1–2 thin and seta-like, [?midapical spine or seta present]. Article 2 of pereopod 5 without facial setae. Peduncle of uropod 1 with dorsolateral spines confined apically, medial spines confined apically or widely spread; peduncle of uropod 2 with only one medial spine or setule confined apically. Peduncle of uropod 3 lacking extra subapical setae or spines. Telson with pair of midlateral or dorsal setules on each side, highly apicad.
