Genus Caraiboscia Vandel, 1968

Caraiboscia Vandel, 1968: 109 .

TYPE SPECIES. — Caraiboscia microphthalma Vandel, 1968 , by monotypy (see Schmidt & Leistikow 2004).

DIAGNOSIS. — Emended after Leistikow (2001a): animals of small size; colorless; dorsal surface bearing fan-shaped or triangular scale-setae; pereonites 1-7 with one line of short noduli laterales per side, d/c coordinates almost on same line, b/c coordinates gradually decreasing; cephalon without frontal line and faint suprantennal line, eyes with 3-4 ommatidia, absent in endogean or troglobionts; telson triangular; antennula of three articles, distal article bearing one row of aesthetascs medially; antennal flagellum of three articles, apical organ long; mandibles with molar penicil dichotomized, left mandible with 2+1 penicils, righ mandible with 1+1 penicils; maxillula outer endite with eight teeth, one or two of them cleft at apex; maxilla with setose lobes; maxilliped endite bearing penicil rostrally; pereopod 1 carpus with transverse antennal grooming brush, distal seta cleft at apex, dactylar seta simple or slightly plumose; uropod protopod and exopod grooved on outer margin, endopod inserted proximally; genital papilla with truncate terminal spatula surpassing ventral shield; pleopod exopods without respiratory areas.

REMARKS

The genus Caraiboscia was erected by Vandel (1968) to include the new species C. microphthalma from Guadalupe Island, Caribbean Sea. Leistikow (2001a) re-described the species, but misinterpreted its country of origin as Equador, probably due to the title of Vandel’s work. Schmalfuss (2003), considering Leistikow’s work, repeated the mistake. The genus Caraiboscia shows affinities with the new genus Nesophiloscia from Galapagos Islands, erected in the same work by Vandel (1968). To date, the genus comprises only two species, C. microphthalma and C. christiani Leistikow, 2001 from Península di Paria, Venezuela ( Schmalfuss 2003), and it shows close phylogenetical relationships with Colombophiloscia Vandel, 1981 ( Leistikow 2001b) .
