( Figs 58–65 )

Length: Male holotype, 7.2 mm.

Male holotype. Head ( Figs 58, 59 ), in dorsal view, well produced anteriorly, anterior margin narrowly rounded; apical portion, in lateral view, slightly directed dorsally; crown with median length 4/5 interocular width and 1/2 transocular width; surface with shallow median fovea; epicranial suture distinct basally, temporal and frontogenal sutures slightly visible. Pronotum ( Figs 58, 59 ), in dorsal view, with width approximately equal to transocular width. Forewings ( Fig. 58 ) with membrane distinct on apical portion, including apical cells.

Ground color of dorsum ( Figs 58, 59 ) dark brown. Crown with small apical yellow macula. Pronotum with transverse yellow macula on anterior two-thirds. Forewings ( Fig. 58 ) dark brown with two pale yellow maculae; anterior one transcommissural, occupying anterior portion of clavus; posterior one on corium, extending from apical portion of claval sulcus to apex of outer discal cell and base of median anteapical cell; apical cells hyaline. Frons with broad pale yellow macula on superior portion extending to anterior margin of crown and antennal ledges, median portion brown, lateral and inferior portions dark brown; clypeus dark brown with pair of yellowish-brown lateral maculae, apex yellow; lateral portions of face dark brown. Lateral portions of thorax and venter brown; legs pale yellow.

Pygofer ( Fig. 60 ), in lateral view, almost twice as long as subgenital plates; macrosetae on apical portion, extending anteriorly along ventral margin; apical portion with ventral inner process bearing numerous setae. Subgenital plates ( Fig. 61 ), in ventral view, gradually tapered toward apex; basal portion with short lateral lobe; ventral surface with macrosetae near outer margin. Styles ( Fig. 62 ), in dorsal view, extending posteriorly beyond apex of connective; with small external median lobe; apical portion beyond lobe curved, with few setae; apex foot-shaped. Connective ( Fig. 62 ), in dorsal view, Y-shaped; arms basally broad. Aedeagus ( Fig. 63 ) with shaft, in lateral view, slightly curved ventrally, with distinct dorsoapical expanded lobe; in ventral view, base with quadrangular lateral expansion and apex expanded laterally. Paraphyses ( Figs 64, 65 ), in dorsal view, with anterior pair of rami broader than posterior one, directed anterodorsally in lateral view; posterior pair longer than anterior one, directed posterodorsally and with ventroapical margin serrate in lateral view; stalk approximately as long as anterior rami. Anal tube (segment X) without processes or areas bearing small setae.

Female genitalia. Unknown.

Etymology. The specific epithet, una, refers to the name of the Municipality of the type-locality.
