Mimoblennius atrocinctus (Regan 1909)

Dorsal spines (total): 13; Dorsal soft rays (total): 18 - 19; Analspines: 2; Analsoft rays: 21 - 22

Oviparous, distinct pairing (Ref. 205).

Closely related to Rhabdoblennius, but differs by 13 dorsal spines. Nasal and nuchal cirri palmate. Supraorbital with 2 long, slender cirri.

A rare species (Ref. 559). Adults live in abandoned worm tubes, solitary or in loose groups (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

DESCRIPTION.—(Meristic characters for holotype in parentheses.) Dentary a closed capsule with replacement teeth entering functional series through foramina in bone. Canine on each dentary posteriorly. Premaxillary and dentary teeth immovable or nearly so; premaxillary teeth 30 to 34 (32); dentary teeth 25 to 30 (26). Vomerine teeth absent. Terminal vertebrae with two epurals and autogenous hypural 5 and ventral hypural plate. Vertebrae 10 + 25 to 28 = 35 to 38 (38); epipleural ribs 15 to 19; last pleural rib on vertebra 10. Circumorbital bones 5.

Dorsal spines 13; last spine noticeably reduced; segmented rays 16 to 19 (17); basal two-thirds of terminal dorsal ray bound by membrane to caudal peduncle; dorsal fin moderately incised between spinous and rayed portions. Anal spines 2; segmented rays 19 to 21 (20); basal two-thirds of terminal anal ray bound by membrane to caudal peduncle. Caudal fin with 13 segmented rays, middle 9 each branched; dorsal and ventral procurrent rays 7. Pelvic rays I,3. Pectoral rays 14 or 15 (14). Pectoral radial formula 2–0–2 (based on 1 cleared and stained specimen). Gill-rakers 10 to 11. Pseudobranchial filaments 5. Nuchal cirri palmate, with 4 or 5 short, rounded branches; supraorbital cirri consisting of 2 long, slender cirri over each eye; anterior nasal cirri palmate, with 3 to 5 branches, posterior nasal cirri absent or minute. Upper and lower lips entire. Lateral line of simple pores ending beneath 4th or 6th dorsal spine or continuous to point below level of 4th dorsal spine, thence curving downward and continuous as short, separate, longitudinally bipored tubes to point opposite tip of median rays of appressed pectoral fin (at level of 11th dorsal spine).

In most specimens the head and body have a pale ground color. The pattern of melanophores is considerably variable. Most specimens bear a dusky mark along the posterior border of the orbit and irregular dusky marks over the opercle. The underside of the head and prepelvic region are dusky to black with occasional evidence of bands under the head. The side of the body may be irregularly dusky, darker on the ventral half, with dark spots at midlevel, or with about 7 vertical dark bands. The dorsal fin usually bears a dark spot between the first two rays, usually paler than in M. cirrosus. There may be dark extensions of the body bands on to the basal portion of the dorsal fin and sundry other dusky marks over the fin. The anal fin may be pale dusky, darker at the ray tips, or almost uniformly black. The caudal fin rays bear dusky spots aligned in irregular vertical rows. The pectoral fin rays are dusky and the pelvic fin rays are dusky to almost black.

The life colors were given by Regan (1909, p. 405) as “reddish, with 6 blackish cross-bars continued on the basal part of the dorsal fin; anal blackish.”

Mimoblennius atrocinctus és una espècie de peix de la família dels blènnids i de l'ordre dels perciformes.

Mimoblennius atrocinctus, the banded blenny, is a species of combtooth blenny found in the western Pacific and eastern Indian oceans. This species grows to a length of 5 centimetres (2.0 in) TL.

This is a rare species in which the adults live along rocky coastline to a depth of 10 metres (33 ft) where they inhabit the abandoned tubes created by worms either alone or in loose aggregations. Their eggs are demersal and adhere to the substrate by an adhesive pad or pedestal which is filamentous. The larvae are planktonic and are frequently recorded from shallow waters near the coast.

It has been recorded from the Indian Ocean off Sri Lanka and Christmas Island while in the western Pacific it has been recorded and from southern Japan to Hong Kong. It has also been recorded from northern Sulawesi and northern Australia.
