Description
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spine: 1; Anal soft rays: 7-8 (usually: 8); Pectoral fin rays: 15-16 (usually: 16), unbranched; Pelvic fin rays: I, 4, unbranched 5th, which is 13.7% the length of the 4th ray, 4th ray bifurcated with each branch about 50% of total length of the ray; Caudal fin rays: 11 branched; Segmented caudal fin rays: 17; Lateral scale rows: 24–26 (usually: 25); Transverse scale rows: 7; Vertebrae: 25. Second, and third dorsal fin spines filamentous in males, extending back to about the third soft ray in the second dorsal fin; Always lacking the POP and IT pores in the cephalic sensory-pore system, and the PITO and AITO pores are fused into one 50% of the time; Male genital papilla non-fimbriate. Very long tubular anterior nares, length almost equal to pupil diameter, reaching well anterior to the upper lip. Max. length : 1.7 cm SL. Depth range: 14 - 73 m.
Color
Background color of head and body translucent white. All markings on body orange. Body crossed by six narrow bars: the first from the front of the first dorsal fin down behind the pectoral-fin base; The second at the posterior end of the first dorsal fin, curving down across the abdomen towards the anus; The third at the third element of the second dorsal fin extending down to the anal-fin origin; The fourth at the sixth element of the second dorsal fin extending down to the anal fin; The fifth running from behind the second dorsal fin down to the posterior end of the anal fin; And the sixth across the caudal peduncle. The nape is crossed by two bars and there is a short bar between the two dorsal fins, another at the posterior end of the second dorsal fin, with a corresponding bar below it at the anal fin, and two short bars at the dorsal and ventral caudal-fin base. The central portion of the caudal-fin base also has a short bar. The area on top of the head behind the eyes has a blotch and the opercular area has another. There are three narrow bars under the eye, the shortest at the posteroventral margin, another ventrally under the eye and extending down across the jaws and the third at the anteroventral edge and also crossing the jaws. Eye pupil black, iris sky blue with red-orange spokes surrounding pupil. Base of anterior tubular nares orange, remainder black. The pectoral-fin base has two blotches, one at the top and the other at the bottom, separated by a translucent white area. Second dorsal fin with brown spots on rays, distal margin dusky. Upper half of caudal fin with brown spots on dusky rays. Anal-fin rays and membranes dusky. Spines of first dorsal fin red-orange with first and second body bars extending onto lower one quarter of fin, a bar of melanophores running across base just above a clear portion along base of fin near dorsum. Pectoral and pelvic fins white.
Etymology
Eviota: from Greek prefix, ev-, eu-, = good or well, very + from Greek letter, iota = smallest letter in the Greek alphabet and often figuratively used to describe anything small or insignificant. Referring to Eviota epiphanes (Jenkins, 1903), which, at 1.0-1.9 cm in length, Jenkins claimed was the “smallest vertebrate that has up to this time been described”.
pinocchioi: named after Carlo Collodi’s fictional character Pinocchio, who had a nose that grew long when he lied, alluding to the exceptionally long anterior tubular nares in this species.
