Introduction

The Condukiidae are an endemic monotypic family described by Barnard & Drummond (1982) from south-eastern Australia. Apparently, members of the family have a mixture of characters found in the Haustoriidae, Urothoidae, Pontoporeiidae and Platyischnopidae (Barnard & Karaman 1991). Nothing is known about the biology, ecology or life histories of this group.

Diagnosis

Antenna 1 shorter than antenna 2; peduncle with many robust or slender setae; peduncular article 1 shorter than article 2; article 2 longer than article 3; article 3 longer than article 1; peduncular articles 2–3 geniculate; primary flagellum 5- or more articulate; callynophore absent. Antenna 2 short; peduncle with robust or slender setae; flagellum shorter than peduncle; 5- or more articulate. Mandible incisor dentate; lacinia mobilis present on both sides; molar fully triturating. Maxilla 1 inner plate weakly setose apically. Maxilliped inner plates well developed; outer plates small. Coxae 1–4 longer than broad, overlapping. Gnathopod 1 subequal to gnathopod 2; subchelate; coxa smaller than coxa 2; carpus longer than propodus. Gnathopod 2 parachelate; coxa smaller than but not hidden by coxa 3; ischium short; carpus long, longer than propodus. Pereopod 3 coxa longer than broad; carpus shorter than propodus, strongly produced posteriorly; dactylus minute. Pereopod 4 coxa larger than coxa 3, with well developed posteroventral lobe; carpus shorter than propodus, strongly produced posteriorly; dactylus minute. Pereopods 5–7 with many rows of facial and marginal robust setae. Pereopod 5 subequal to pereopod 6; coxa smaller than coxa 4, with ventrally produced posterior lobe; basis expanded, with posteroventral lobe; carpus expanded; dactylus minute. Pereopod 6 subequal to pereopod 7; basis expanded. Pereopod 7 subequal to pereopod 5; basis expanded. Uropods 1–2 apices of rami with robust setae. Uropod 3 biramous; peduncle short; rami styliform; outer ramus longer than peduncle. Telson laminar; deeply cleft; longer than broad; dorsal robust setae present; apical robust setae absent.
