status

sp. nov.

Glaucorhoe exilaria Han & Xue   , sp. nov.

Figs. 8–9 View FIGURES 2 – 9 .

Description. Body: Head, body and wing patterns same as the previous two species. Length of forewing: ɗ 13–14 mm, Ψ 14–15 mm.

Male genitalia ( Figs. 15 View FIGURES 10 – 15 , 21 View FIGURES 16 – 21 , 25). Uncus long and stout, coniform, well sclerotized, ciliate. Valva with posterior ends of costal lobe and sacculus blunt, the former slightly shorter and distinctly narrower than the latter, slightly more than one half of sacculus in width; the long setae at the posterior end of costal lobe straight and pointed outwards; ventral margin of sacculus protrudent near base. Saccus short, with a tiny blunt process. Juxta, aedeagus as in redescription of the genus.

Female genitalia ( Fig. 29 View FIGURES 26 – 29 ). As in redescription of the genus.

Diagnosis. The wing shape and patterns of G. e x i l a r i a are close to those of G. unduliferaria   and G. magaria   , but it differs genitalically: the length of the saccus is less than 1 / 5 of the uncus in G. exilaria   , shorter than in G. unduliferaria   and G. m a g a r i a, in which the length of the saccus is circa 1 / 4 of the uncus; in G. exilaria   , the middle width of the costal lobe is slightly more than one half of the sacculus, whereas in G. magaria   , the middle width of the costal lobe is less than one half of the sacculus, and in G. unduliferaria   both parts are almost the same width; G. e x i l a r i a also differs from G. unduliferaria   and G. magaria   in having a costal lobe shorter than the sacculus; G. e x i l a r i a is distinguishable from G. unduliferaria   in that the long setae at the posterior end of costal lobe are straight and pointed outwards.
