Zyginella dworakowskae sp. nov.

Figs 1–3 , 39–47

Description. Body brown and shining, lateral marginal stripe and median stripe on vertex reddish-orange, rest of vertex grey-brown ( Figs. 1 ). Frons white, frontoclypeus, anteclypeus and lorum dark brown, gena white ( Fig. 3 ). Pronotum grey-brown with lateral dark brown broad stripes not reaching hind margin. Scutum grey with basal triangles and median dark brown stripe on scutellum ( Fig. 1 ). Forewing transparent and infuscate with brown veins, long oblique brown stripe from midlength of clavus to middle of corium, brochosome field with elliptical dark red patch, brown stripe along apical veins, third apical cell with distinct dark spot ( Figs. 1, 2 , 40 ). Hind wing transparent with brown veins ( Fig. 41 ).

Male abdominal apodemes slender, reaching midlength of sixth sternite ( Fig. 39 ).

Male genital capsule short, pygophore side extended centrally and truncated terminally, with short, sclerotized process internally and directed ventrally, with six long macrosetae posterodorsally, numerous small setae along posterior margin ( Fig. 42 ). Subgenital plate tapered in basal half, with apex sclerotized and hooklike, with two macrosetae and some microsetae centrally ( Figs. 42, 45 ). Paramere with long, tapering curved apical part and with a row of thin setae subapically ( Fig. 44 ). Connective short, V-shaped ( Fig. 43 ). Aedeagus with preatrium long and dorsal apodeme developed; shaft with basal pair of processes longer than shaft; gonopore apical ( Figs. 46, 47 ).

Body length. 2.91–3.10 mm (including wing).

Material examined. Holotype, 13, China: Yunnan Prov., Mt. Baoshan, 19 Nov. 1999, coll. I. Dworakowska. Paratypes, 53, 14Ƥ, fig tree, same data as holotype.

Distribution. China (Yunnan)

Remarks. The new species resembles Z. processa sp. nov., but differs in having a dark brown scutellum, dark red brochosome field and smaller dark spot in the third apical cell of the forewing ( Figs. 1, 2 ); Z. processa sp. nov. has a yellow scutellum, red brochosome field and larger dark spot in the third apical cell of the forewing (Figs. 13, 14). It also differs from all the known species of Zyginella in having basal processes of the aedeagal shaft exceeding the length of shaft ( Figs. 46, 47 ).

Etymology. The new species is named in honor of Dr Irena Dworakowska for her contribution to the knowledge of World Typhlocybinae .
