DIAGNOSIS

The genus Angustalius has a conspicuously produced apex on the forewing. The wing pattern is similar to that of the Holarctic genus Crambus , with a broad white fascia running across the discoidal cell. Male genitalia exhibit the following characters: uncus slender, elongate, bent downwards, apex pointing downwards; gnathos very short, without distal projection; valva with sclerotized costa, without projection; sacculus sclerotized, separated from valva; vesica usually with one cornutus. Female genitalia exhibit the following characters: papillae anales somewhat subrectangular; anterior and posterior apophyses strongly reduced or absent; ostium simple, sclerotized; ductus bursae short; corpus bursae with two signa ( Błeszyński, 1965).

DISTRIBUTION

Occuring in the Afrotropical, Oriental, and Australasian regions. Six species are reported in the genus worldwide, of which only Angustalius malacelloides (Błeszyński, 1955) is found in the Philippines.
