Family CEINIDAE J.L. Barnard, 1972

Introduction

In this study the Ceinidae retain all the genera of the Ceininae, but for pragmatic reasons genera prevously considered in the Chiltoniinae are placed in the Hyalidae (Lazo-Wasem & Gable 2001). Bulycheva (1957), Bousfield (1983, 1996) and Zeidler (1991) would place these genera in the Hyalellidae. A dichotomous key to these species is presented in Bradbury & Williams (1999).

The Ceinidae is a small, talitridan family of three genera known from southern South America, New Zealand, Australia and the southern Philippines. In Australian waters only two species, from the Great Barrier Reef and south-western Western Australia, are currently known. Nothing is known about their biology.

 

Diagnosis

Head as long as deep or deeper than long; anteroventral margin weakly or moderately recessed and shallowly or moderately excavate; anteroventral corner rounded or subquadrate; rostrum short or absent; eyes round or ovoid. Body laterally compressed; with deep sensory pits and dorsally carinate. Antenna 1 shorter than, subequal to, or longer than antenna 2; peduncular article 1 longer than article 2; article 2 subequal to, or longer than article 3; article 3 shorter than article 1; accessory flagellum absent; primary flagellum 5- or more articulate; callynophore absent. Antenna 2 short; flagellum shorter than, as long as or longer than peduncle; less than or more than 5-articulate. Mandible incisor dentate; lacinia mobilis present on both sides; molar fully or weakly triturating or spike-like; palp absent. Maxilla 1 inner plate weakly setose apically; palp large, reduced or absent, 1-articulate. Maxilliped inner plates well developed; outer plates large or small. Coxae 1–4 overlapping. Gnathopod 1 not sexually dimorphic; smaller (or weaker) than or subequal to gnathopod 2; subchelate; coxa vestigial, hidden or partially hidden by coxa 2 or subequal to coxa 2; carpus shorter than or subequal to propodus. Gnathopod 2 sexually dimorphic or not; subchelate; coxa subequal to but not hidden by coxa 3; ischium short or long; carpus short or long, shorter or longer than propodus. Pereopods some, all or none prehensile; 3–4 not glandular. Pereopod 3 coxa longer than broad; carpus shorter than or subequal to propodus, not produced. Pereopod 4 coxa larger than coxa 3, with well developed posteroventral lobe; carpus shorter than or subequal to propodus, not produced. Pereopod 5 shorter than pereopod 6; coxa smaller than coxa 4, with ventrally produced posterior lobe, with posterodorsal lobe or without posterior lobe; basis expanded, subrectangular, subquadrate or subovate, with or without posteroventral lobe; carpus weakly expanded; dactylus with a few subterminal setae. Pereopod 6 shorter than or subequal to pereopod 7; basis expanded; dactylus with a few subterminal setae or without setae. Pereopod 7 longer than pereopod 5; basis expanded or slightly expanded, subovate. Pleonites 1–3 each with or without dorsal carina; each with dense patches of short dorsal setae. Urosomite 1 much longer than urosomite 2; urosomite 1 carinate or urosomites not carinate or urosomite 3 carinate. Uropods 1–2 apices of rami with or without robust setae. Uropod 3 peduncle short; rami absent. Telson laminar or weakly thickened dorsoventrally; moderately or weakly cleft or entire; broader than long; dorsal and apical robust setae absent.
