A Review of the Labrid Genus Paracheilinus, with the Description of a New Species from Melanesia

The genus Paracheilinus Fourmanoir, previously known from a single specimen collected in the Red Sea, is reviewed and a new species is described from New Guinea and the Solomon Islands. Paracheilinus, which was not adequately defined when introduced by Fourmanoir, is a member of the labrid subfamily Cheilininae, which also includes Cheilinus, Cirrhilabrus, Pseudocheilinops, and Pseudocheilinus. It appears to be closely allied to Cirrhilabrus. The two genera are similar in body shape, dentition, and behavior. Paracheilinus filamentosus n.sp. differs from P. octotaenia Fourmanoir primarily on the basis of color pattern and shape of the head, dorsal fin, and caudal fin

Psammogobius pisinnus, a new species of reef goby (Teleostei: Gobiidae) from Papua New Guinea and Australia

A new miniature species of gobiid fish, Psammogobius pisinnus n. sp., is described from West New Britain Province, Papua New Guinea on the basis of 10 specimens, 10.8–17.9 mm SL. Diagnostic features include dorsal-fin rays VI + I,9 (rarely I,10), the third dorsal-fin spine sometimes with a short, filamentous extension; anal-fin rays I,9 (rarely I,8); pectoral-fin rays 16–19 (usually 17); the pelvic fins reaching the anal-fin origin; the pelvic frenum weakly developed; longitudinal scales 25–28; the tongue distinctly bilobed, and a live color pattern that is generally light gray to whitish with three broad brown saddles on the dorsal half of the body. The new species differs from the three previously described species of Psammogobius (P. biocellatus, P. knysnaensis, and P. viet) on the basis of its tiny adult size (less than 20 mm vs, about 70–80 mm SL), fully marine habitat (vs. brackish estuaries and tidal streams), possession of cheek and opercular scales (scaleless in other species, except P. biocellatus with scales on the upper portion of the opercle), only 5–7 predorsal scales (vs. 10–16), and color pattern. The new species is also reported from the northern Great Barrier Reef of Australia on the basis of a single specimen

A new species of Parapercis (Teleostei: Pinguipedidae) from the Solomon Islands.

A new species of pinguipedid fish, Parapercis binotata, is described from the Solomon Islands on the basis of six adult specimens, 46.5–56.5.5 mm SL. The new taxon belongs to the Parapercis cylindrica complex, which contains five other western Pacific Ocean species: P. australis, P. cylindrica, P. haackei, P. lineopunctata, and P. snyderi. It is most similar to P. lineopunctata from the East Indian Archipelago, but adult males are clearly distinguished by the presence of two short black bands, one on the cheek and another on the lower pectoral fin. Although lacking these markings, females differ from those of P. lineopunctata by the presence of a curved black band below the eye. The only known habitat of the new species consists of a nearly enclosed lagoon in 4-8 m depth. Analyses of the mtDNA “barcode” marker COI sequences for the P. cylindrica species complex show exceptionally deep divergences between most species, about 15–20% divergence between all but one pair of species, with P. binotata 14.52% different from its nearest relative, P. lineopunctata

Description of five new species of marine gobies (Teleostei: Gobiidae) of the genus Grallenia from the tropical western Pacific Ocean.

Five new species belonging to the gobiid fish genus Grallenia of the tropical western Pacific Ocean are described from sand-bottom habitats. G. compta n. sp. (11 specimens, 14.9–17.3 mm SL) from Milne Bay Province, Papua New Guinea and G. rubrilineata n. sp. (81 specimens, 8.8–15.8 mm SL) from Luzon, Philippines share a suite of features that comprises an absence of cephalic sensory-canal pores, a rectangular first dorsal fin without a filamentous extension of the first spine, and the anterior and posterior scales separated by a scaleless gap, with 15–22 longitudinal scales in the posterior series. The two species differ from each other in dorsal- and anal fin-ray counts (8–9 for G. compta n. sp. vs. 9–11, usually 10, for G. rubrilineata n. sp.), scalation patterns, and coloration. A third new species, Grallenia dimorpha n. sp. (34 specimens, 9.8–16.7 mm SL) from Papua New Guinea is similar, except it has a continuous series of longitudinal scales without a gap, and females possess a triangular first dorsal fin featuring a filamentous extension of the first spine. The last two species, Grallenia lauensis n. sp. (two females, 11.1–11.4 mm SL) and G. solomonensis n. sp. (three females, 11.4–12.5 mm SL), are described from Fiji and the Solomon Islands, respectively. They exhibit similar diagnostic features including the presence of cephalic sensory-canal pores, usually 7 segmented dorsal- and anal-fin rays, and most body scales restricted to the caudal peduncle. Grallenia solomonensis n. sp. differs from G. lauensis n. sp. in having several mid-lateral scales immediately behind the pectoral-fin base (vs. none), 16 (vs. 15) pectoral-fin rays, pelvic-fin rays with 2–3 branch points (vs. a single point), and a truncate (vs. slightly emarginate) caudal fin. An additional 33 non-type specimens, 7.0–15.6 mm SL, from Australia (southern Great Barrier Reef and northwestern Coral Sea) are provisionally identified as G. lauensis n. sp. However, at least some Australian specimens differ slightly in possessing branched segmented dorsal-fin rays and pelvic-fin rays with more than one branch point. Although fins are damaged in most specimens, two Australian males exhibit a long, filamentous first dorsal-fin spine

Development of N/P AlGaAs free-standing top solar cells for tandem applications

The combination of a free standing AlGaAs top solar cell and an existing bottom solar cell is the highest performance, lowest risk approach to implementing the tandem cell concept. The solar cell consists of an AlGaAs substrate layer, an AlGaAs base layer, an AlGaAs emitter, and an ultra-thin AlGaAs window layer. The window layer is compositionally graded which minimizes reflection at the window layer/emitter interface and creates a built-in electric field to improve quantum response in the blue region of the spectrum. Liquid phase epitaxy (LPE) is the only viable method to produce this free standing top solar cell. Small (0.125 sq cm), transparent p/n AlGaAs top solar cells were demonstrated with optimum bandgap for combination with a silicon bottom solar cell. The efficiency of an AlGaAs/Si stack using the free standing AlGaAs device upon an existing silicon bottom solar cell is 24 pct. (1X, Air Mass Zero (AM0). The n/p AlGaAs top solar cell is being developed in order to facilitate the wiring configuration. The two terminal tandem stack will retain fit, form, and function of existing silicon solar cells. Progress in the development of large area (8 and 16 sq cm), free standing AlGaAs top solar cells is discussed

Chrysiptera uswanasi, a new microendemic species of damselfish (Teleostei: Pomacentridae) from West Papua Province, Indonesia.

Chrysiptera uswanasi, n. sp., the seventh member of the Chrysiptera oxycephala species complex of Pomacentridae, is described on the basis of 10 specimens, 24.7–45.3 mm SL, collected at the Fakfak Peninsula of New Guinea (West Papua Province, Indonesia). The new taxon is a microendemic species, found only in a small area around the Fakfak Peninsula. It differs from other members of the group, C. burtjonesi (Solomon Islands), C. ellenae (Raja Ampat Islands, West Papua Province in Indonesia), C. maurineae (Cenderawasih Bay, West Papua Province), C. oxycephala (central Indonesia, Philippines, and Palau), C. papuensis (NE Papua New Guinea, and C. sinclairi (Bismarck Archipelago and islands off NE Papua New Guinea), on the basis of its distinctive color pattern and a 9.3% divergence in the sequence of the mitochondrial control region from its closest relative (C. oxycephala). Adults are mainly greenish yellow grading to pearly gray ventrally with numerous small blue or greenish spots on the head, body, and basal portion of the dorsal, anal, and caudal fins, and juveniles have a distinctive bright blue snout and forehead. The adult differs from the adults of most of the other members of the group in lacking bright yellow on the ventral body, including the pelvic and anal fins. The two other species in the complex that are also lacking bright yellow ventral bodies and fins are C. ellenae, which differs in being overall more green and having an all blue juvenile stage, and C. sinclairi, which is mostly dark blue, both as adults and juveniles

A new species of damselfish (Chrysiptera: Pomacentridae) from coral reefs of the Solomon Islands

A sixth member of the Chrysiptera oxycephala group of Pomacentridae, Chrysiptera burtjonesi, is described on the basis of 24 specimens, 20.5–48.2 mm SL, collected at the Solomon Islands in the western Pacific Ocean. It differs from other members of the group, including C. ellenae (Raja Ampat Islands, West Papua Province in Indonesia), C. maurineae (Cenderawasih Bay, West Papua Province), C. oxycephala (central Indonesia, Philippines, and Palau), C. papuensis (northeastern Papua New Guinea), and C. sinclairi (Bismarck Archipelago and islands off northeastern Papua New Guinea), on the basis of its distinctive color pattern and a 6.9% divergence in the sequence of the mitochondrial control region from its closest relative (C. maurinae). Adults are primarily grayish brown to greenish except bright yellow on the ventralmost head and body, including the adjacent pelvic and anal fins. Juveniles are mostly neon blue to dark blue with bright yellow pelvic and anal fins. In addition, it is the only species besides C. sinclairi that usually lacks embedded scales on the preorbital and suborbital bones

Descriptions of four new species of damselfishes (Pomacentridae) in the Pomacentrus philippinus complex from the tropical western Pacific Ocean.

Four new species of Pomacentrus, allied to P. philippinus, are described from the western Pacific Ocean. Pomacentrus albiaxillaris, n. sp. is described on the basis of 81 specimens, 14.5–70.0 mm SL, from the Palau Archipelago in Micronesia. It was formerly considered to be a Palauan population of P. emarginatus Cuvier, a species of uncertain status from Waigeo in West Papua. However, the two species differ in appearance and morphology and the new species from Palau has never been observed at Waigeo and surrounding areas despite extensive surveys by the authors. Pomacentrus albiaxillaris differs from other members of the philippinus complex in possessing a white pectoral-fin axil; a small dark spot that is restricted to the uppermost portion of the pectoral-fin base (instead of a large black marking that covers the entire fin base); a whitish caudal fin; and a bright blue dorsal scleral surface of the eye. Pomacentrus flavoaxillaris, n sp. is described on the basis of 28 specimens, 49.5–72.9 mm SL, from Micronesian locations east of Palau, including Ulithi Atoll, Chuuk, Pohnpei, and Kosrae. Additional photographic and literature records include Ngulu Atoll, Yap, and the Mortlock Islands. It is similar to P. albiaxillaris n. sp. in having a white caudal fin and blue dorsal scleral surface of the eye, but differs in having a yellow inner pectoral-fin axil, a large black spot covering the entire pectoral-fin base, white zones at the bases of the posteriormost dorsal- and anal-fin rays, and a whitish caudal peduncle. Pomacentrus magniseptus, n. sp. is described from 24 specimens, 34.6–75.6 mm SL, collected at the Great Barrier Reef of Australia. It differs from other members of the philippinus complex by its unique color pattern, consisting of horizontal rows of pale spots on the side of the body and entirely blackish median fins. It also differs from most relatives in always lacking scales on the preorbital and most of the suborbital. Pomacentrus nigriradiatus, n. sp. is described on the basis of 48 specimens, 28.8–86.9 mm SL, from Samoa, Rotuma, Wallis Island, Loyalty Islands, New Caledonia, and Vanuatu. Diagnostic features include highly contrasting dark fin rays on the posterior portions of the dorsal, anal, and caudal fins, as well as the lack of a contrasting marking on the inner pectoral-fin axil. It also differs from P. albiaxillaris and P. flavoaxillaris in usually having at least a few scales on the preorbital. Genetic evidence is also provided to resolve relationships among the four new species and P. philippinus. The divergence in the mtDNA sequence of three concatenated markers between these species ranges from 5.1–7.4% (in average pairwise distances), with the closest relationship between P. flavoaxillaris and P. magniseptus. The four new species differ by an average of 12.9% in mtDNA sequence from the type population of P. philippinus in the Philippines
