Euborellia caraibea Hebard

Euborellia ambigua (Borelli 1909), Rehn and Hebard, 1917, p. 638 [partim].

Euborellia caraibea Hebard, 1922, p. 322.

Not represented in the present material, but recorded by Rehn and Hebard (1917) from Roseau, Dominica.

Shining black or dark brown; antennae brown, basal segments paler; legs yellowish brown, femora darker on external faces. Head and pronotum similar to those of ståli; elytra relatively large, meeting or overlapping along sutures; wings absent or concealed; a small scutellum visible. Abdominal tergites 6–9 of male rugose laterally and each tergite with a lateral ridge on each side. Branches of forceps of both sexes similar to those of ståli.

WORLD DISTRIBUTION.—Restricted to the West Indies. Recorded from Bahamas, Cuba, and Jamaica, as well as Dominica, by Hebard (1922).

Psalis Serville, 1831, p. 34 [no type-species cited] [preoccupied by Psalis Huebner, 1823, Lepidoptera].

Carcinophora Scudder, 1876a, p. 291 [type-species: Chelidura robusta Scudder, 1869, by original designation].

Spandex Burr, 1915, p. 537 [type-species: Psalis pulchra Rehn 1903, by original designation].

Rather small to very large species; elytra always present, and wings usually visible; dark brown to blackish, sometimes partly yellow or red; elytra with yellow spots or patches or entirely dark, wings dark or partly yellow. Pronotum relatively small; abdomen not greatly widened or depressed. Male genitalia similar to those of Anisolabis, but virga usually more prominent and more or less indurated; parameres generally acuminate.

Entirely Neotropical in distribution.

One species is recorded from Dominica.

Carcinophora percheron (Guerin-Meneville and Percheron)

Forficula percheron Guerin-Meneville and Percheron, 1839, p. 6 [French Guiana].

Forficula flexuosa Burmeister, 1838, p. 753 [French Guiana; Guyana].

Spongophora bipunctata Scudder, 1862, p. 415 [? Mass., U.S.A.].

Psalis pulchra Rehn, 1903, p. 303 [Costa Rica].

Labia pictipennis Bruner, 1906, p. 138 [Trinidad].

Carcinophora percheron (Guerin-Meneville and Percheron), Popham and Brindle, 1966, p. 275.

This species appears to be most common in Trinidad, which may be its main center, but it has also been recorded from South and Central America. It does not appear to have been previously recorded from Dominica. The above record for Massachusetts is doubtful, since Scudder (1876a) when suggesting the synonymy of bipunctata with the present species, remarked that the specimen was presumably from Massachusetts, but, if so, “very probably imported.” Reichardt (1968) has published the above synonymy.

Length: body 13–18 mm., forceps 2–3 mm. Blackish, shining; head reddish, sometimes darker; antennae blackish, first two segments yellow and one or more distal segments white; pronotum yellow laterally; each elytron with a large yellow or reddish yellow spot; wings reddish yellow at base; legs yellow. Head broad, eyes small, pronotum narrow, widest anteriorly; elytra and wings always fully developed. Abdominal tergites punctured. Male forceps with branches trigonal at base, cylindrical distally, each branch not strongly curved; those of female similar but branches straighter and more contiguous.
