Gerald R. Allen, Mark V. Erdmann and Meity U. Mongdong: Tomiyamichthys eyreae, a new species of shrimpgoby (Gobiidae) from West Papua, Indonesia, pp. 1-10
A new species of gobiid fish, Tomiyamichthys eyreae, is described from the Daram island group in the Southeast Misool marine protected area of the Raja Ampat Archipelago in West Papua Province, Indonesia, on the basis of two male specimens, 21.8-37.7 mm SL. Diagnostic features include 9 segmented dorsal and anal-fin rays, 17 pectoral-fin rays, 55-56 lateral and 14 transverse scales, cephalic sensory system containing pores B’, C, D, E, F, G, H, M’, N, and O’, no prepectoral scales, ctenoid posterior body scales, and color pattern containing 3-4 large diffuse, dark blotches on side of body interspersed with large, irregular white blotches, diagonal orange bands anteroventrally on side, grading to diagonal rows of small orange spots on posterior half of body, head with numerous orange spots and short bands, and rear portion of first dorsal fin and entire second dorsal and caudal fins with orange spots. Type specimens were collected from a gradually sloping, sand/rubble-bottom exposed to moderate to strong currents in 28 m depth.
Gerald R. Allen, Mark V. Erdmann and William M. Books: Feia seba, a new species of marine goby (Pisces: Gobiidae) from Papua New Guinea, pp. 11-16
Feia seba, n. sp. is described from a single male specimen, 12.8 mm SL, collected from a sandy-mud bottom habitat in 30 m depth at Milne Bay Province, Papua New Guinea. Diagnostic features include: lateral scales 32; predorsal scales 13; a few scales on upper operculum; pelvic frenum absent, basal membrane fully developed; papillae rows on chin parallel, not converging posteriorly; raised fleshy ridges associated with cephalic sensory papillae mainly confined to preopercular-mandibular series, those of opercle and cheek weakly developed; live coloration mainly reddish brown with widely-spaced, vertically elongate white markings below dorsal-fin base and on dorsal edge of caudal peduncle, also scattered white spots on cheek, opercle, and dorsum of head; dorsal and caudal fins dark brown with white markings.
Tyson R. Roberts: Quintabarbates bicolor, a new genus and species of cobitid Fish from the Middle Chindwin Basin in Myanmar, pp. 17-20
Quintabarbates bicolor, a new genus and species of cobitid fish is described, which superficially resembles smaller members of the speciose Southeast Asian genus Pangio but differs from all species of that genus in having five instead of only four pairs of barbels and an immobile suborbital bone without a spine instead of a highly moveable one with a large sharp recurved erectile spine. About a dozen specimens had originally been collected in the lower courses of tributaries of the Middle Chindwin River in northern Myanmar between Tamanthi and Khampti, exclusively from the bottom of deep accumulations of leaf litter. In life all were brilliantly colored with full-length deep stripes of gleaming or iridescent green and orange, totally unlike the life color of any species in Pangio or other cobitid genera. Standard lengths of all individuals collected were less than 30 mm.
Gerald R. Allen, Mark V. Erdmann and Nur Hidayat: Choeroichthys hadiatyae, a new species of pipefish (Syngnathidae) from the Fakfak Peninsula of West Papua Province, Indonesia, pp. 21-27
A new species of syngnathid pipefish, Choerichthys hadiatyae is described from the Fakfak Peninsula of West Papua Province, Indonesia on the basis of a single female specimen, 34 mm SL collected from coral reef habitat in 2–15 m depth. It is distinguished from other members of the genus on the basis of a combination of features including 16 dorsal-fin rays, 11 pectoral rays, 15 trunk rings, 25 tail rings, and overall dark coloration with pronounced white bars ventrally on lower jaw and radiating from eye, and white spots and short bands along edge of gill opening. It also has a shorter head (7.0 in SL) and shorter snout (2.9 in head length) compared to congenerics.
