Macropharyngodon pakoko, a new species of wrasse (Teleostei: Labridae) endemic to the Marquesas Islands, French Polynesia

A new species of wrasse, Macropharyngodon pakoko, is described from the Marquesas Islands, bringing the total number of species of the genus Macropharyngodon to 12. Macropharyngodon pakoko was found at depths from 0-42 m and is endemic to the Marquesas Islands. Macropharyngodon pakoko is similar to M. meleagris, which is widely distributed from the central and western Pacific to Cocos-Keeling in the Indian Ocean, but differs genetically and in several coloration characters: males with irregularly curved black humeral blotch with incomplete iridescent blue border; inverted irregular “U”- shaped band on the cheek; a small black spot at the upper base of the pectoral fin; and background color of the body greenish with faint bluish black spots on each scale. Females lack black pigment on the chest posterior to the ventral attachment of the gill membranes; reddish black blotches on the body are widely spaced, particularly on the head where they are more reddish and half the size of those on body; caudal fin with small, bright yellow spots arranged in narrow vertical bands with pale interspaces; pelvic fins pale with three reddish yellow cross-bands; a small black spot at the upper base of the pectoral fin; and small reddish spots along the base of the anal fin. Juveniles have irregular black blotches on the body, a small black spot instead of an ocellus posteriorly on the dorsal fin and lack large black spots and ocellus on the anal fin.

Ocellus-bearing Neobythites species (Teleostei: Ophidiidae) from the West Atlantic with description of a new species

Three species of the ophidiid genus Neobythites containing ocelli in the dorsal fin are known from the West Atlantic: Neobythites gilli Goode and Bean 1885, N. ocellatus Günther 1887 and N. monocellatus Nielsen 1999. In the year 2000, 18 specimens of Neobythites were caught on the upper continental slope off eastern Brazil. This is the first documented record of a Neobythites specimen off Brazil since the holotype of N. ocellatus was caught in 1873. Seventeen of the specimens are referable to N. ocellatus and one to N. monocellatus. Until now the distribution of N. ocellatus was considered to be from off Atlantic Florida, the Caribbean Sea and then a gap of 4500 km to the type locality off Brazil. However, the holotype and the 17 specimens differ from the more northerly recorded specimens in pattern and number of spots and ocelli on the dorsal fin. The 18 Brazilian specimens have two distinct ocelli, one near the origin of the dorsal fin and one above the midpoint of the fish, and further back occasionally a small, black spot, while the northern specimens occasionally have a small, black spot near the origin of the fin, a distinct ocellus above the midpoint and up to three ocelli further posteriorly. Consequently a new species, N. multiocellatus, is described based on 59 specimens from the Caribbean Sea to off Atlantic Florida. The record of the N. monocellatus specimen extends its distribution about 3000 km southwards. A comparison of the four ocellus-bearing species from the West Atlantic is made.

Revision of Coelana Kramer, 1964 (Hemiptera, Cicadellidae, Neocoelidiinae) and taxonomic notes on the genus

Coelana Kramer [= Coelidiana subgenus Coelana DeLong nomen nudum] is revised and its two species, Coelana modesta (Baker) and Coelana drakei Kramer are redescribed. Coelana can be distinguished from other genera of Neocoelidiinae by the presence of a small black spot at the apex of the crown and male genitalia with an inflated pygofer, longer than subgenital plates, with a large ventral hook and laterally with a long suture, extending from the ventral margin to near the dorsal margin. The species are redescribed and illustrated, their geographical distribution is given, and a lectotype for Neocoelidia modesta Baker is designated.

Heterochromatin Distribution in the Chromosome Complement of Triturus boscai (Amphibia: Caudata: Salamandridae)

The C-banding pattern of the I berian endemism Triturus boscai has been analyzed using mitotic chromosomes from gastric tissue and testes. The chromosome pairs are characterized for presenting a small black spot on their centromeres although a pair of pericentric bands are placed on both sides of the centromere region. Some chromosomes are characterized by the presence of terminal and subterminal bands. Present results are compared with those referred to related species within the group Triturus.

NEW SPECIES OF GEOMETRIDAE WITH NOTES, II

Male. Palpi extremely short and stubby. Antennae slightly compressed laterally but not particularly thickened. Primaries light smoky gay, sprinkled with deeper smoky. Basal space light gray, bordered outwardly by a strong black oblique line which is angled rather sharply below costa and then somewhat concave outwardly to vein I, ending in a small black spot on inner margin.

On some Egg-parasites from Africa

♀. Head shining green; face and front with purplish shine. Thorax orange-yellow, with a small black spot on each side of the pronotum; mesopleurae and propodeon slightly brownish. Abdomen aeneous-black, with dark green shine near the end; first segment (except two brown spots at the sides) and second segment (except hind border) whitish. Valvae of ovipositor white. Antennae brown, with scape and pedicel yellow. Wings dark brown, with the base and a bent stripe in the middle hyaline. Legs brownish yellow, with the trochanters and tip of tibiae and tarsi clearer yellow; base of hind coxae and a stripe on the inner side of middle and hind femora dark brown.
