Gabonola gen. n.

(Figs 13, 27)

Type species: Gabonola smithi sp. n.

Diagnosis. The male genitalia of Gabonola gen. n. is characterized by the fully sclerotized dorsal lobe of the valva bearing a rounded subapical lobe and a long, acute apical process in contrast to the ventrally membranous, apically rounded dorsal valval lobe of Hampsonola lacking any lobes or processes. While the harpe is well-developed in Hampsonola, it is fully reduced in Gabonola, substituted by a curved, sclerotized band lacking any prominence or process. The configuration of the ventral lobe of the valva is highly characteristic in its dense distal scobination. Compared to Vandamia van Son, the new genus lacks the conspicuous hair tuft of the uncus and the dorsal valval lobe which are diagnostic features in the former genus, while Vandamia always has an apically rounded dorsal valval lobe and a well-developed harpe.

Description. Adult. Male (Fig. 13). Forewing length of type species 6.7 mm. Head small, antenna bipectinate with short, finely ciliate rami; labial palp short, porrect, cream; frons and vertex cream. Collar, tegula, mesothorax and abdomen brown. Forewing elongate-triangular, apically rounded, ground colour ochreous brown. Transverse lines diffuse, consisted of small darker brown patches. Cilia long, dark brown. Hindwing greyish-brown, veins and cilia darker than ground colour. Underside of wings greyish-brown.

Male genitalia (Fig. 27). Uncus moderately long, narrow, apically rounded. Tegumen short and very narrow; subscaphium membranous, sparsely scobinate. Valva broad basally, bilobate distally, dorsal lobe relatively broad, elongate, uniformly sclerotized, postmedially with a semi-circular lobe, apically with a long, robust, acute process. Ventral lobe of valva short, relatively broad, rounded, distal half densely scobinate. Sacculus large, roundedtrapezoidal, weakly sclerotized, without processes. Juxta very narrow, V-shaped with long lateral arms. Vinculum robust, V-shaped, heavily sclerotized. Aedeagus short and narrow, dilated at ostium ducti ejaculatorii, coecum elongate, rounded, distal half of aedeagus digitiform, subapically slightly curved, apically broadly rounded; vesica without cornuti or scobination.

Etymology. The generic name refers to the country of origin of the new noline taxon.
