Litobranchus fowleri (Herre 1936)

Oviparous, distinct pairing (Ref. 205).

Dorsal spines (total): 12; Dorsal soft rays (total): 18 - 20; Analspines: 2; Analsoft rays: 20 - 22

Inhabits tidepools and rocky shores.

Adults are found in tide pools and rocky shores to a depth of over 9 m. 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 jawbone. Posterior dentary canines present (frequently absent in females). Premaxillary and dentary teeth immovable or nearly so; premaxillary teeth 36 to 42; dentary teeth 28 to 30. Vomerine teeth absent. Terminal vertebra with two epurals and autogenous hypural 5 and ventral hypural plate. Vertebrae 10 + 27 or 28 (usually 28) = 37 or 38; epipleural ribs 13 or 14; last pleural rib on vertebra 10. Circumorbital bones 5.

Dorsal spines 12; last spine moderately reduced; segmented rays 18 to 20(19); 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 20 to 22(21); basal two-thirds of terminal anal ray bound by membrane to caudal peduncle. Caudal fin with 12 segmented rays, none branched; dorsal procurrent rays 5 to 8 (usually 6), ventral rays 4 or 5. Pelvic rays I,3. Pectoral rays 14. Pectoral radial formula 2–0–2. Gill-rakers 6 to 8(7). Pseudobranchial filaments 5. Nuchal, supraorbital, and nasal cirri simple. Upper and lower lips entire. Pores of infraorbital series simple. Lateral line short, continuous to point below 4th to 6th dorsal spine, pores simple.

PIGMENTATION.—The pigmentation of the sexes closely approaches that shown in Figure 12. Males are characterized by 7 dark lateral bands that extend across the dorsum, several rows of pale, horizontally elongated spots on sides, and the fins not heavily pigmented, except distally on the interradial membranes of the anterior 4 or 5 dorsal spines. In several of the largest (presumably nuptial) males the head is very dark. In the females there are no rows of pale spots and the lateral bands are less well defined. In contrast to the males, the body and the dorsal fin are characterized by numerous dark spots.

GEOGRAPHIC VARIATION.—The three New Guinea specimens differ in several respects from the other material and were not used in preparing the above description. We provisionally assign these specimens to Litobranchus fowleri.

In specimens from the Palaus, Philippines, and Indonesia, the supraorbital cirri are minute and there is no apparent sexual dimorphism associated with these structures. In 7 females (21.8–31.0 mm SL) the ratio of the cirrus length into the orbital diameter was 4.3 to 8.5, average 5.6; in 10 males (22.4–34.0) the ratio was 4.0 to 8.0, average 5.4. The New Guinean specimens have longer cirri that clearly reflect sexual dimorphism. In the single female specimen the cirri/orbital ratio is 1.8; in both males it is 0.65. In all three specimens the number of dentary teeth is low, 23 (versus 28 to 30). The number of premaxillary teeth is within the range of those shown by the other specimens.

The interradial membranes of the anal fin are more deeply incised and the anal segmented rays approximately one-third longer in New Guinean males than in Philippine males of nearly equal size. The New Guinean males also differ in having the body almost completely devoid of pigment, but this may be the result of fading.

Litobranchus fowleri és una espècie de peix de la família dels blènnids i de l'ordre dels perciformes.

Litobranchus fowleri, Fowler's rockskipper, is a species of combtooth blenny found in coral reefs in the western Pacific ocean. It can reach a maximum length of 3.5 centimetres (1.4 in) SL. This species is currently the only species in its genus. The specific name hours the American ichthyologist Henry Weed Fowler ((1878-1965).

Litobranchus fowleri es una especie de pez de la familia Blenniidae en el orden de los Perciformes.
