Description
Craspedometra amboinae A. H. Clark, 1912a: 35 (list); 1918: 78 (footnote); Reichensperger 1913: 99.
Heterometra amboinae —A. H. Clark 1918: 78 (key); 1941: 297, pl. 29 fig. 123, pl. 31 figs 131–136; A. M. Clark and Rowe 1971: 22 (key).
Material examined. 2 specimens. Lombok Is. NSMT E-8249 (2 specimens), Kodek, February15, 1994.
Description (larger specimen). Centrodorsal discoidal, 7 mm across, 3 mm thick, with cirrus sockets in 1–2 irregular rows and flat aboral pole. Cirri stout, XXIII, 33–35, 25– 30 mm long. Cirrals wholly shorter than wide; beyond about 11 th with prominent aboral spine. Radials wholly concealed by centrodorsal. IBr 2: Ibr 1 oblong, in contact laterally; Ibr 2 (axil) low triangular, free laterally. IIBr 4(3+4). Arms stout, 16, 135 mm long; first syzygy at br 3+4; br 4 –br 10 about 3 times wider than long with parallel articulation, beyond br 10 wedge-shaped. P 3 longest, stiffened, 20 mm long, of 30 segments; proximal pinnulars shorter than wide with a keel toward tip. P 2 similar to P 3, but slightly shorter. P 2 and P 3 much longer and stouter than PII and P 1.
Remarks. Four Heterometra species, namely H. variipinna (Carpenter, 1882), H. affinis (Hartlaub, 1890), H. amboinae (A. H. Clark, 1912a), and H. sarae A. H. Clark, 1941, were recorded from Ambon (A. H. Clark 1941). In these 4 species, H. amboinae is the most closely related to H. sarae in sharing excessively short middle-distal brachials. According to A. H. Clark (1941: 230–232), brachials beyond br 4 are 3–4 times wider than long in H. amboinae, while 6–8 times wider than long in H. sarae. Based on these characteristics, present specimens were identified with H. amboinae.
Distribution. Sri Lanka, Singapore, Indonesia (A. H. Clark 1941; A. M. Clark and Rowe 1971). Depth range: 0–50 m (A. H. Clark 1941).
