Prins, Jurate De & Kawahara, Akito Y., 2012, Systematics, revisionary taxonomy, and biodiversity of Afrotropical Lithocolletinae (Lepidoptera: Gracillariidae), Zootaxa 3594 (1), pp. 1-283 : 42-43

The landryi group

The landryi consists of three species: C. landryi De Prins , n. sp., C. varii De Prins , n. sp., and C. fara De Prins , n. sp. Forewing ground colour of this group ochreous with white/black markings consisting of three transverse sinuoid fasciae, directed towards apex. The fasciae possess indistinct, intermingling margins with dense suffusion of blackish fuscous scales. Hostplants of the landryi group are unknown.

Male genitalia have very diverse characters that are characteristic to each species: very narrow straight valva in C. varii and broader, curved valva with an acuminate apex in C. landryi ; complete transtilla in C. varii and incomplete in C. landryi ; well developed, tubular anellus in C. landryi , whereas the anellus is not developed in C. varii ; clefted vinculum with short saccus in C. landryi and U-shaped vinculum with long (ca. as long as sternum VIII) saccus in C. varii .

The female genitalia similar to those in the hexalobina group, characterized by ostium bursae opening located at the posterior margin of segment VII. Anterior apophyses absent in C. varii , but present in C. landryi and C. fara . Corpus bursae bears one round or oval signum crossed by straight median ridge ( C. landryi , C. varii ) or signum is dentate ( C. fara ).
