1. Colapteroblatta sp. 1 ( Fig. 4 ), NEW RECORD

Diagnosis. Nymph 17 mm, relatively convex and elongate, pale yellowish brown and mottled dark brown; dorsum with dense, dark punctures, plus 5 very irregular longitudinal fields of brown markings, leaving margins of pronotum pale yellow-brown. Frons mostly dark ferruginous, vertex slightly darker with 3 pale, narrow, interocular stripes; antennomeres basally straw-colored, then progressively darker; pronotum disc convex, margin thickened and flared upward, with a large, irregular, mottled brown central area, and sides yellow with dark punctures; rest of dorsum irregularly spotted with dark brown, forming 5 longitudinal series, of which the middle series is the least developed; venter pale straw and dark brown, with 2 darker mottled lateral fields that are wider posteriorly and connected across the last sternite; pale lateral margins continuous to cerci, then abruptly narrowed to a thin line; cerci very short, 1 segmented, straw-colored; legs pale with dark-tipped spines and scattered dark spots; posterior ridges of femora narrowly edged with dark brown.

Comments. In the most recent revision of the Antillean species of the genus Colapteroblatta , there is no mention of Virgin Islands ( Gutiérrez 2012a). This only specimen was found in the wet zone of Sage Mountain on Tortola. Our species may be related with C. portoricense described from a tropical wet forest on Puerto Rico by Gutiérrez and Roth (1999), but we need adults for confirming the taxonomic status.

Specimen examined. BDVC — 1 female nymph, BVI, Tortola Is., Sage Mt., 1600–1700 ft., 6.X.2001, B. & B. Valentine.
