Acailandica , gen. n.

Type-species: Acailandica acailandiae , sp. n.

Diagnosis. Acailandica is a telochromatic genus characterized by the orange ground colour of the forewing. The species are externally similar to those of Hilarographa Zeller, 1877 (Chlidanotinae) and Mictopsichia Hübner , [1825] ( Tortricinae ). The male genitalia of Acailandica are similar to those of Satronia Heinrich , but the former have a more specialized, bifid uncus. Male genitalia of Acailandica are also somewhat similar to those of Ricula Heinrich , but Ricula have an atrophied uncus and distinct digitate socii. All these genera have a similar valva and aedeagus and a reduction of other characters typical of Grapholitini. The female genitalia of these grapholitine genera are poorly known, hence comparisons among them are not particularly meaningful.

Description. Head: Typical of the tribe. Thorax: Forewing fairly broad; forewing venation (examined in A. maja ) with M5 to apex, M3-CuA1 well separated at base, chorda strong from 2/3 distance between bases of R1-R2 to ½ distance between M1-M2; hindwing Rs-M1 stalked to 1/4; M2 widely separated from Cu1A at base; M3-Cu1A connate. Abdomen: Male genitalia with tegumen moderately long; pedunculi slender; socii absent; uncus bifid posteriorly; gnathos and tuba analis weakly sclerotized; sacculus convexly rounded; neck of valva distinct, ventral incision broad; cucullus elongate, tapering terminad; aedeagus simple, moderately broad, pointed ventroterminally; cornuti not found. Female genitalia with ovipositor short; apophyses slender; sterigma subsquare, weakly sclerotized except for proximal and lateral edges; antrum of thick membrane, usually slightly sclerotized proximally; cingulum variable in size, weakly sclerotized; corpus bursae with one or two funnel-shaped signa.

Distribution and biology. The genus is distributed in South America from British Guiana to central Brazil (Maranhão, Pará, Rondônia, Amazonas). Adults were collected in January and September.

Etymology. The generic name refers to the type locality of the type-species, Acailandia, Brazil.

Remarks. Seven species are included. The above description of the male genitalia is based on the type-species, A. acailandiae , that of female on A. maja , sp. n.
