NO. 3590 MICROLEPIDOPTERA, XIII — DUCKWORTH 3 



opinion, listed Loxotoma in the Stenomidae part of the "Lepidoptero- 

 rum Catalogiis" series with three inchided species, elegans, semini- 

 grescens, and liniella (Busck), the latter a species that Biisck (1910, 

 p. SO) had described and placed in Stenoma. Clarke (1955, p. 223) 

 illustrated the wings and genitalia of the type of rhodanthes Meyrick 

 and reiterated its synonymy with L. elegans. Duckworth (1962, 

 p. 113) transferred liniella (Busck) from Loxotoma to Timocratica, 

 thus reducing the number of species of Loxotoma to the two covered 

 in this paper. 



Genus Loxotoma Zeller 



Loxotoma Zeller, 1854, p. 383. 



Type-species: Loxotoma elegans Zeller, by monotypy. 



Head rough, lateral tufts somewhat spreadmg. Labial palpus 

 large, sharply recurved; second segment thickened ventrally with 

 appressed scales; apical segment acute, shorter than second. Fore- 

 wing with costa arched sharply at midpoint then tapering to apex, 

 apex sharply rounded, termen slightly oblique, tornus rounded; with 

 12 veins, all separate, 3 and 4 approximate, 6 and 7 approximate, 7 to 

 apex, 12 somewhat sinuate due to sharp arch in costa. Hindwing 

 broader than forewing; with eight veins, 3 and 4 connate or stalked, 

 5 approximate to 3 and 4, 6 and 7 stalked. Abdomen of males with 

 strong, eversible pair of hair pencils contained in an elongate cuplike 

 pocket on first sternum. 



Male genitalia; Harpe broad, rounded at apex, saccular margin 

 with numerous short, heavy setae; anellus with four lateral lobes 

 that adhere closely to aedeagus; uncus broad, slightly recurved, with 

 setiferous dorsal hump at apex; arms of gnathos separate. 



Female genitalia: Ovipositor lobes long, narrow: tergite and sternite 

 of eighth abdominal segment fused laterally forming a complete ring; 

 anterior apophyses short, heavy, laterally curved; ductus bursae, 

 corpus bursae, membranous; signum consisting of two heart-shaped 

 dentate plates connected by a narrow sclerotized band. 



This genus is easily recognized on the basis of its size and wing shape. 

 It is related to the genus Timocratica in both superficial characters 

 and structures of the genitaUa; however, it is readily separated by the 

 separate gnathos in the male genitalia and the fusion of the eighth 

 tergite and sternite in the female genitalia. 



Key to Species of Loxotoma Based on Color

ground color of forewing yellow brown elegans Zelhu* 



Hindwing dark gray on basal half, becoming ro«y brown po.steriorly; ground 



color of forewing orange brown seminigrescens Meyrick
