Genus COLPOMERIA Holmgren 



Colpomeria Holmgren, 1859. Svenska Vetensk.-Akad., Ofvers af ... Forhandl. 16: 126. 

 Type-species: Colpomeria laevigata Holmgren. Monotypic. Townes has most 

 recently been treating Colpomeria as a synonym of Acrodactyla, apparently 

 because of the structural intermediates of one Formosan species, C. orientalis 

 (Cushman). Except in C. orientalis, females of this genus have a prominent tooth 

 on the front femur and a weaker one (sometimes vestigial) on the middle femur. 

 The femoral teeth seem significant enough to warrant recognition of Colpomeria 

 as a distinct genus; it also has secondary distinguishing features found only in a 

 few species of Acrodactyla. 

 quadrisculpta (Gravenhorst). N. S. s. to Ga., w. to Alaska and Calif.; Eurasia. Host: 



Tetragnatha laboriosa Hentz, T. obtusa C. L. K. In North America quadrisculpta is 

 known to have been reared only from T. laboriosa.

 Panteles mellithorax Ashmead, 1900 (1899). In Smith, N. J. State Bd. Agr., Ann. Rpt. 27, 



Sup., p. 575. Nomen nudum. 

 Polysphincta albocoxalis Ashmead, 1902. In Slosson, Ent. News 13: 320. Nomen nudum. 

 Colpomeria mellithorax Cushman, 1920. U. S. Natl. Mus., Proc. 58: 19. 9. The type locality 

 is D. C; on page 10 of the paper in which he described mellithorax, Cushman quoted 

 notes which presumably pertain to the cocoon of the holotype of mellithorax, not to the 

 female of Toxophoroides scituhis (Cresson).
