From editor or global species database
Diagnosis Extremely small species of Dorometra with arm length not exceeding 30 mm, rarely over 20 mm. Centrodorsal low hemispherical, 1.3 mm in diameter. Cirri slender, up to 30 in number, 10 segments, 3.5 mm long; elongate cirrals ~3.5 times longer than median width; distal end flared, overlapping base of following segment; aboral spines absent; opposing spine and terminal claw prominent. Brachials entirely smooth. Pinnules relatively small and slender. Proximal pinnulation incomplete; P1, P3 and Pc always present; but P2 and P4, sometimes rudimentary or absent; Pa, Pb and Pd more frequently absent; pinnulation not uniform on each ray of a specimen. P3 longest proximal pinnule, up to 1.7 mm in length, 8 segments, slightly longer than P1, about as long as or occasionally shorter than middle and distal pinnules. P2 and P4 (if present) much shorter than P3. Comparative lengths of proximal pinnules: P1 > P2 << P3 > P4 < P5. P3 to as far as P13 bearing gonads, and spawned eggs frequently attached to such pinnules. Hermaphroditic. [details]

Distribution Sesoko-jima Islands and Maeda-misaki, Okinawa, Ryukyu Islands, Japan. Depth range: 10-25 m. [details]

Ecology On reef slopes characterized by dead coral rubble, with dense populations on the undersides of the rubble. On the coasts of Sesoko-jima Island, population density reached more than 40 individuals per 0.25 m2. Such aggregations consisted of variously sized individuals, not only adults but also settled cystideans and pentacrinoids. [details]
