Color
In alcohol, back and upper surfaces brown, variegated with darker and paler marblings. Eight diffuse or obscure median darker blotches on back. Sides of head and body with more defined and contrasted dark spots on sides. Eyes gray, with silvery tints and darker markings. All under surfaces of body immaculate whitish. First dorsal dark gray to gray-black, especially on second and third membranes; some paler longitudinal lines on first two membranes. Second dorsal transparent, with scattered dark spots or specks on rays. Anal pale, dark to blackish brown m.arginally. Caudal whitish, gray terminally, and with a dozen irregular transverse rows of dark to kackish spots. Pectoral whitish, with numerous small, irregular, blackish-brown spots above. Ventral pale to whitish basally, dark to blackish brown termuially, and inner half of fin with connecting membrane marked with small dark to blackish dots.
Etymology
Callionymus: from Greek, kallos = good, beautiful + from Greek suffix, -onym = name, word, with a better name. Callionymus (Linnaeus, 1758) is also the latinization of kallionymos, Aristotle’s name for stargazers (Uranoscopidae), which Linnaeus apparently confused with dragonets.
keeleyi: named for Frank J. Keeley, of the department of mineralogy, Academy of Natural Sciences of Philadelphia.
Original description: Callionymus keeleyi Fowler, 1941 - Type locality: Cebu, Philippines.
Distribution
Western Pacific: Philippines, Papua New Guinea, Australia, New Caledonia.
Biology
Juveniles are found in sandy bottom.
