Chrysobothris thoracica guadeloupensis Descarpentries, 1981: 181 .

Diagnosis. Male. Frons bright metallic green, densely punctate, concolorous with vertex; ventrally curved whitish hairs present on lower one-third to one-half of frons; first three antennomeres bright metallic green. Pronotum metallic reddish with a distinct green spot just anterior of the scutellum. Front tibia slightly widened distally just beyond middle, without tooth-like process. Elytra ( Fig. 2 ) with the anterior foveae weakly impressed, posterior pair indicated by color but not impressed; green coloration at elytral base does not extend along lateral margin to first fovea; extreme apices of elytra with greenish coloration. Male genitalia ( Fig. 5, 6 ) with parameres more robust than in C. thoracica and slightly more arcuate in ventral view ( Fig. 6 ); aedeagus nearly parallel-sided just before apex, slightly curved dorsally. Length 4.5–5.5 mm.

Female. Frons bright golden orange, significantly differing in color from male. Front tibia as in male. Length 5.3–6.2 mm.

Biology. Touroult (2005) recorded Chrysobothris guadeloupensis from tamarind, Tamarindus indica L. ( Fabaceae ); white mangrove, Laguncularia racemosa ; and Acacia tortuosa (L.) Willd. ( Fabaceae ). Adults were reared from larvae in these three host plants from small diameter branches (2–5 cm). Touroult (2005) stated that the species was widespread in Guadeloupe, principally in the xerophilic zone and sporadically in the mesophilic zone.

Remarks. Touroult (2005) provided some additional locality records for C. guadeloupensis from Guadeloupe, and recorded it from the nearby island of La Désirade.
