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 89.5.15.147) 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
.
