Notes.

This species reaches 12.0 × 5.0 mm and is relatively broader than Pemba’s other subulinids. It was found only in high moist forest at Ngezi (Table 2). It keys out to Curvella subvirescens using Verdcourt’s (2002) key and resembles the types at BMNH. Verdcourt (2006) records Curvella subvirescens from the Nguru Mts. and Uluguru Mts. and notes its similarity to the Tanzanian Curvella sinulabris (von Martens, 1878) and Kenyan Curvella pertranslucens Preston, 1910, the latter described from the Shimba Hills ( Preston 1910).
