Mortoniella enchrysa Flint 1991

Mortoniella enchrysa

This is the only species in the genus that I have seen which is covered with golden hair and lacks the two transverse white lines on the forewing. The male genitalia are also distinctive. The hirsute basoventral lobe of the tenth tergum, and clawlike ventral process of the aedeagal complex are distinctive.

ADULT.—Length of forewing, 5–6.5 mm. Color golden; body pale brown; forewing, head and thorax covered with golden hairs; hindwing fuscous. Sixth sternum of male with a small apicomesal process. Male genitalia: Ninth segment with anterior margin rounded and produced anteroventrally; posterior margin produced into a midlateral acute angle. Tenth tergum with apical lobes well divided mesally with apicolateral margin darkened; lateral lobe lightly sclerotized, apex rounded; with a hirsute ventrolateral lobe. Aedeagal complex with a single dorsomesal process, enlarged at midlength, and with tip narrow and angled dorsad; lateral process long, pointed; ventral margin bearing small teeth; with a lateroventral rounded lobe, beneath which is an elongate process ending in 2 strong, ventrally-directed teeth.
