Coscinia Hübner   , [1819]

Type species: Phalaena cribrum Linnaeus, 1761   , by subsequent designation by Hampson, 1901. Catalogue of the Lepidoptera Phalaenae   in the British Museum 3, 203-204 (but cited as Phalaena cribraria Linnaeus, 1758   ). ( Fig. 41 View FIGURES 41–44 )

Diagnosis. Distinct from Sagarriella   , Spiris   and Lerautia   in the uncleft tip of the valva (but straight, dentate valva apex in Spiris striata   ) and the sclerotized spiny band extending through the bursa. Further distinct from Spiris   and Lerautia   in the apically pointed or rounded uncus and the small, oval to triangular sclerotized plate on the lamella antevaginalis. Distinct from Sagarriella   in the U-shaped, narrow saccus (less so in C. mariarosae   ), and distinct from Spiris   in the absence of a clavus on the base of valva.

Description. Imago. Head and thorax large, frons uniformly covered with scales, labial palps well developed, proboscis moderately long, functional; antenna of male bipectinate, with moderately long ramifications, that of female filiform; eyes large, hemispherical, ocelli reduced or absent. Thorax and abdomen covered with uniform scales. Tibia of foreleg with a long, thin and pointed spur. Forewing narrow and pointed; hindwing long, large and rounded with slightly concave outer margin.

Male genitalia. Valvae short, roughly rectangular, with a characteristic fold in the central part of the inner surface, apically with a wide club-shaped cucullus; pollex ending in a strong medioventrally directed curved spine. Aedeagus cylindrical, slightly curved, with a bulbous coecum and a sclerotized plate in the centre of the vesica.

Female genitalia. Bursa with a strongly sclerotized spinose band, constricting the anterior centre of the corpus bursae symmetrically or asymmetrically ( C. mariarosae   ) into two pockets, one of which with two small circular signa; cervix bursae elongated, wide and membranous (except in C. mariarosae   , that has is sclerotized), finishing in a membranous sac from which the ductus seminalis emerge; ductus bursae broad, strongly sclerotized ( Table 1 View TABLE 1 ).
