Kapalana   g. nov.

Type species. Kapalana durraween   sp. nov., present designation.

Included species. Kapalana   includes 8 species: K. amelga   sp. nov.; K. durraween   sp. nov.; K. flindersi ( Stebbing, 1888)   comb. nov.; K. kimbla   sp. nov.; K. maia   sp. nov.; K. michaelmas   sp. nov.; K. stebbingi   sp. nov.; K. wadei   sp. nov.

Etymology. Named for the retired New South Wales Fisheries vessel FRV Kapala   , the source of many Australian Museum fish and invertebrate collections from 1971 to 1997. The name is feminine in gender.

Diagnostic description. Head with eyes present, rostrum long to very long. Antenna 1 without accessorY flagellum; peduncular article 1 not produced anterodistally and anteromedially into an opercular cap, posterior margin with strong subquadrate or acute posterior projection. Antennae 1–2 peduncular articles 1–3 covered in scales [except K. amelga   , K. maia   and K. flindersi   ]. Gnathopod 2 carpochelate in male. Pereopod 5 propodus inserted on posterior concave side of carpus. Pereopods 5–7 directed posteriorly. Pereopods 6–7 similar, much longer than pereopod 5. Uropod 1, peduncle with distoventral fan of robust setae. Uropod 2–3 uniramous. Tubes of juveniles attached in a ring, circling the tube of adult female (not known for K. flindersi   ).

Remarks. Kapalana   has the strongest similarities to Runanga J. L. Barnard, 1961   , Cerapus   and Paracerapus Budnikova, 1989   . Kapalana   differs from these genera in having a projection on the posterior margin of the first article of antenna 1 and in Kapalana   , the juveniles attach their initial tubes to the mother tube.

The species known as Cerapus flindersi Stebbing, 1888   is based on a female from Flinders Passage in Torres Strait, northern Queensland. It has never been re-collected and the tube is not known. The specimen is held in The Natural History Museum, London (BMNH and consists of four microscope slides. Based on the morphology of antenna 1 peduncular article 1, we tentatively move it to the genus Kapalana   .

Walker & Scott (1903) reported a female from Abd al Kuri, in the Gulf of Aden that they called Cerapus flindersi   and Chilton (1892) reported a male Cerapus flindersi   from Port Jackson, Australia, but in both cases the species identification is dubious. Walker & Scott’s specimen is poorlY illustrated. Chilton’s specimen lacks a projection on the posterior margin of the first article of antenna 1 and represents an undescribed species of Cerapus   .
