Caryocolum interalbicella species-group

The Caryocolum interalbicella species-group was defined by Huemer (1988) and is characterized in the male genitalia by the following characters: uncus long and narrow; tegumen very broad anteriorly, strongly constricted medially, with large pedunculi; transtilla with spines; valva usually long and slender, subbasally strongly bent, apex frequently bulged, with brush of setae; sacculus knife-shaped; posterior margin of vinculum medially incised to broadly emarginated; saccus slender to moderately broad; phallus without cornuti. Female genitalia are characterized by the following characters: segment VIII with pair of ventral or dorsal processes, ventromedial area sclerotized with or without microtrichia; antrum short ring to long funnel; signum with a semi-oval basal plate and a strong distal hook. The species-group includes 18 species ( Huemer 1988; Huemer and Karsholt 2010, 2020).

The informal Caryocolum tricolorella subsection is characterized by a long and evenly slender valva without apical bulge in the male genitalia, and a large, broadly funnel-shaped antrum in the female genitalia.
