Coridromius carinatus ( Carvalho 1956) , new combination Figures 4, 6, 8G, map 3

Coridromoides carinatus Carvalho, 1956: 54–55 (n. sp.).

DIAGNOSIS: Recognized by the swollen callar region, anterior projections of the humeral angles (fig. 4) and stylate eyes (figs. 4, 6). C. carinatus is most similar to boianotum , with both species sharing similar pronotal projections, coloration, texture, and male genitalia. Female unknown.

REDESCRIPTION: COLORATION (figs. 4, 6): Head: Pale brownish-orange; frons without brown vittae. Antenna: Pale yellow- orange, apex of AI and AII, base of AIII, and all of AIV slightly brown. Thorax: Mostly brownish-orange, paler ventrally; pronotal collar yellowish orange, brown laterally; pronotum brownish orange with pale medial stripe bordered by darker brownish-orange fields; mesoscutum dark brownish orange; scutellum brownish orange with two broad lateral brown spots. Hemelytra: Somewhat translucent brownish yellow, becoming darker orange on clavus, especially along scutellar margin. Legs: Yellowish orange, metafemur with five or six light brown diagonal stripes. Abdomen: Brownish yellow. SURFACE AND VESTITURE (figs. 4, 6): Head and scutellum smooth, glossy and impunctate; pronotum glossy and highly sculptured with deep, irregular punctures; propleuron, metepimeron, and hemelytra impunctate; head and dorsum clothed in short, white, decumbent setae. STRUC- TURE (figs. 4, 6): Head: Wide, eyes stylate; frons broadly tumescent medially; vertex without paired tumescences adjacent to eyes; posterior margin of head strongly rounded medially and carinate along lateral margins. Thorax: Pronotum highly sculptured and campanulate, anterolateral margins thin and carinate, projecting forward as distinct lobes, callar region greatly swollen, posteri- or margin flared upward and strongly carinate, humeral angles broadly rounded; proepisternum unilobed; posterior margin of metepimeron truncate; scutellum swollen. Hemelytra: Costal margin straight and narrowly carinate; cuneus narrow and long. Legs: Metatibial spines short and thin. Abdomen: When viewed laterally, posterior margin of abdominal sternite II not angular. MALE GENITALIA (fig. 8G): Right para- mere simple and rounded; left paramere thin and weakly curved; posterior margin of pygophore without groove, fold, or mesal suture. FEMALE PARAGENITALIA: Unknown.

REMARKS: Although the pronotal shape and stylate eyes of carinatus are unique to this species, all other characters—including the male genitalia—are typical of Coridromius . We do not find that this species differs enough from Coridromius to justify its own genus, and therefore synonymize Coridromoides as a junior synonym of Coridromius .

HOST: Unknown.

DISTRIBUTION: Known only from a single specimen from Palau (map 3).
