Zyginella petala sp. nov.

Figs 10–12, 48–56

Description. Body brown and shining, eyes black, anterior part of vertex pale yellow medially (Fig. 10). Face brown, frontal area pale (Fig. 12). Pronotum, scutum and scutellum dark brown, scutellum with apex yellow (Fig. 10). Forewing brown, clavus with two large yellow patches, one nearly pentagonal and another triangular, with brown fascia between them, brochosome field with elliptical red patch (Figs. 10, 11). Hind wing transparent, with brown veins ( Fig. 50 ).

Male genital capsule short, pygophore side acute, with short, sclerotized process internally and posteroventrally, and with spine-like process dorsally, with seven long macrosetae postero-dorsally and several small setae along posterior margin ( Fig. 48 ). Subgenital plate parallel-sided, with apex long and narrow, abruptly curved laterad, with two macrosetae and a few microsetae subapically ( Figs. 52, 54 ). Paramere with long, tapering bent apical part and with numerous thin setae subapically ( Fig. 53 ). Connective short, V-shaped ( Fig. 51 ). Aedeagus with preatrium long and dorsal apodeme well-developed; shaft long, with two rows of small teeth on lateral margin of midlength, with five fingerlike processes apically, resembling petals of a flower; gonopore apical ( Figs. 55, 56 ).

Body length. 2.64–2.80 mm (including wing).

Material examined. Holotype, 13, China: Yunnan Prov., Menglun, Ficus , 8 Dec. 1999, coll. I. Dworakowska. Paratypes, 13, 2Ƥ, same data as holotype. 1Ƥ, 9 Dec. 1999, Macaranga , same data as holotype.

Distribution. China (Yunnan)

Remarks. The new species resembles Z. punctata (1985) , but differs in the pentagonal and triangular patches of the forewing clavus and the red patch of the brochosome field (Figs. 10, 11); Z. punctata has a continuous large patch on the forewing clavus and a black patch on the brochosome field (Figs. 16, 17). In male genitalia it can be distinguished from Z. punctata by the absence of a long serrated subapical process of the subgenital plate ( Figs. 54 , 31), by presence of two rows of teeth on the lateral margin of the aedeagus near the midlength and by the fingerlike apical processes of the aedeagal shaft, all absent in Z. punctata ( Figs. 55, 56 , 32, 33).

Etymology. The specific epithet is derived from the Latin word “ petala ”, referring to the petal-like apical part of aedeagus.
