Description
Dorsal spines (total): 4; Dorsal soft rays (total): 8; Anal spines: 0; Anal soft rays: 7. Unbranched infraorbital canal, very short upward and downward branches of lateral line. Anal fin dark with many darker spots. First dorsal spine is extended with a filament in males. This species has double series of small pearly spots along lower sides. Max length : 10.0 cm TL. Depth range 5 - 40 m.
Dorsal rays IV-vi or vii,l ; anal v or vi,l ; pelvics 1,5; pectorals ii,15 or 16; branched caudal 4+3. Head to tip of free opercular flap 3.1 to 3.3; head to rear tip of preopercular spine 2.9 to 3.2; greatest depth of body 7.1 to 7.4; longest ray of pectoral 4.5 to 4.8 and of pelvic 3.5 to 4.0; all in standard length. Snout 3.4 to 4.1; eye 4.4 to 4.7; postorbital length of head to tip of opercular flap 1.8 to 2.1 and to tip of preopercular spine 1 .G to 1.9; tip of snout to posterior edge of maxillary 3.2 to 4.0; longest pectoral ray 1.3 to 1.6; longest pelvic ray 1.1 to 1.4; all in length of head to tip of preopercular spine. Least width of interorbital space 5.0 to 5.5 in eye.
Head depressed, snout depressed and slightly concave, projecting shghtly beyond tip of lower jaw; premaxillaries protractile, not quite reaching to tip of snout when fully retracted ; teeth villiform, in a wide band at front of premaxillary, narrower laterally; teeth in lower jaw villiform and arranged similarly; no teeth on vomer or palatmes; a free dermal flap at rear of opercle that usually does not quite reach to opposite tip of preopercular spine; preopercular spine rather elongate and straight, about 3,5 times in length of head to tip of preopercular spine; a small antrorse spine near base of preopercular spine and 9 or 10 serrae along upper edge, mcluding the dorsaUy curved spiny tip; gill opening above opercle in the form of a small foramen; the membrane connecting the pelvic fin with the pectoral base is joined to latter opposite bases of third to fifth rays from top; two lateral lines, the dorsal one with an arch over pectoral fin then behind it, extending near midlengthwise axis of body, the lower lateral line has a fleshy dermal keel along lower side of body, beginning about opposite base of second anal ray; body and head naked; maxillary at its posterior extremity semitubular, with an anteriorly projecting very short concave lobe; no orbital tentacle.
There is considerable sexual dimorphism: Males have the first spiny ray of dorsal greatly elongate or threadlike, usually not quite reaching to base of last dorsal ray, and an anal papilla is present on adults; the female specimen has the first dorsal spine scarcely longerthan second, and no anal papilla.
Etymology
Diplogrammus: Greek, diploos = twice + Greek, gramma = mark, signal.
goramensis: From the locality type Goram Archipelago in The Malay Archipelago.
Original description: Callionymus goramensis Bleeker, 1858 - Type locality: Pulau-Pulau Gorong, Molucca Islands, Indonesia, Banda Sea.
Distribution
Western Pacific: Vietnam, Philippines and eastern Indonesia east to Marshall and Cook Islands, north to southern China, south to Australia, Norfolk Island and New Caledonia.
Biology
Inhabits coastal bays and estuaries, over sand, mud, or dead coral rubble of lagoons and outer reef slopes. Feeds mainly on small benthic invertebrates. Usually buried in substrate. Occurs in small groups. May also be solitary.
Similar species
Diplogrammus xenicus (Jordan & Thompson, 1914) - Eastern Indian Ocean and Western Pacific: southern Japan and the Ryukyu Islands and from the west and east coasts of Australia around 30°S - Not reported from New Caledonia - Diplogrammus goramensis is closely related to Diplogrammus xenicus in having short upward and downward branches of the lateral line, similar coloration of the second dorsaland caudal fins in males, and similar coloration of the first and second dorsal and anal fins in females. Diplogrammus goramensis differs from Diplogrammus xenicus in having an unbranched tip of the infraorbital canal (tip branched in the latter) and in the coloration of the anal fin in adult males.
Synchiropus rosulentus (Randall, 1999) - Eastern Central Pacific: Hawaiian Islands and Johnston Island. Not reported from New Caledonia. Males with five irregular brown blotches dorsally on body and a row of seven orange pink blotches along side linked dorsally by a midlateral narrow orange pink stripe; two small jet black spots above base of each pelvic fin; broken blue lines (brown in preservative) on head below eye, continuing onto gill membranes and pectoral-fin base where alternating with yellow.
