6. Eupteryx (Stacla) gracilirama View in CoL sp. nov.

( Figs 33–42 View FIGURES 33 – 42 )

Description. Body dull yellow. Vertex and pronotum mostly dark brown with symmetrical yellow spots. Vertex with three yellow spots anteriorly and one posteriorly; coronal suture slightly yellow. Pronotum with 5 faint parallel longitudinal yellow stripes medially and bilaterally. Scutellum yellow medially. Forewing with two round yellow patches in basal half and several round colourless patches in apical half. Hindwing slightly infuscated with longitudinal veins brown ( Figs 33–35 View FIGURES 33 – 42 ). Dorsum of abdomen brown, venter yellow excepting last 2 segments light brown.

Abdominal apodemes extending to middle of 5th segment. Hind margin of pygofer side rounded and slightly produced with several small rigid setae apically, and base of ventral margin with a row of rigid setae ( Figs 36–37 View FIGURES 33 – 42 ). Subgenital plate with long macroseta basally, and with row of microsetae at outside margin apically ( Fig. 38 View FIGURES 33 – 42 ). Outer margin of paramere bent at acute angle subapically ( Fig. 39 View FIGURES 33 – 42 ). Connective Y-shaped, with lateral arms slender. Aedeagus shaft with pair of long, slender S-shaped ventral processes and Y-shaped median dorsal process apically, ventral processes extending to base of shaft with outer margins bearing few irregularly placed spines; dorsoatrium slender ( Figs 40–42 View FIGURES 33 – 42 ).

Measurement. Male 3.06 mm and female 3.07 mm (including wing).

Type material. Holotype, ♂, Yunnan Prov., Dali, altitude 2000m, Labiatae , 11. XI. 1999, coll. Dworakowska; Paratype, 2♀♀, same data as holotype; 3♀♀, Tengchong, altitude 2000m, Artemisia , 26. XI. 1999, coll. Dworakowska.

Notes. The new species closely resembles Eupteryx pentavittatus Hu & Kuoh in the external appearance, but its patch on vein ScP+RA is smaller than the patch in the 4th apical cell which is opposite to the condition in Eupteryx pentavittatus . Moreover, the male genitalias are distinctive: the paired processes at the apex of aedeagus in the new species are lacking in Eupteryx pentavittatus .

Etymology. The specific name is derived from a combination of the Latin prefix “gracil-” (slender) and the Latin word “rama” (twig), which refers to the aedeagal processes.
