Name

Canalirogas van Achterberg & Chen, 1996 – Wikispecies link – Pensoft Profile

• Canalirogas van Achterberg & Chen, 1996: 63–64. Type-species (by original designation): Canalirogas balgooyi van Achterberg & Chen, 1996 (examined; = Canalirogas spilonotus (Cameron, 1905), syn. n.).

Diagnosis

Canalirogas can be separated from related genera by the combination of (1) hypopygium of female distinctly convex ventrally and strongly enlarged (Figs 15, 21, 30, 35, 41, 47, 56, 64, 69, 78); (2) ovipositor distinctly curved downwards (Figs 30, 41, 64, 78); (3) ovipositor sheath widened (Figs 15, 25, 30, 47, 56, 64, 78); (4) second metasomal tergite without distinct medio-basal area (Figs 3–4, 6–11, 18, 37, 54, 62, 76); (5) anterior half of fourth-fifth tergites usually (partly) obliquely striate; (6) tarsal claws simple. The vertex is smooth, the prepectal carina complete, the tarsal claws simple, the hind tibia with apical comb on inner side and the dorsope is present.

Biology

Parasitoids of Lymantriidae on clove trees (Quicke and Shaw 2005).
