description: Atkinsoniella cuspidata sp. nov.
(Figs. 15–28)
Description. Length of males 7.6–8.1mm, females 8.1–8.5mm.
Body dorsum black with yellow to orange markings. Crown with large median longitudinal spot at anterior half and smaller irregular spot near each ocellus attaining lateral margin; eyes dark brown with yellow to orange margin. Pronotum with discontinuous median orange transverse band. Scutellum mostly orange, apical angle black in some females. Forewing black with three longitudinal stripes, one in clavus almost covering all of its surface, other two in corium. Face pale yellow with distinct Y-shaped black stripe in all females, in males usually indistinct or absent. Lateral and ventral portion of thorax black. Abdomen mostly black; sternites with posterior margins pale yellow. Legs pale yellow with tarsal apex black.
External features resemble A.biundulata sp. nov. Head with median length of crown one-half interocular width. Forewing with four apical cells, base of second cell more proximal than base of third, or aligned transversely. Hindleg with femoral setal formula 2:1:1.
Male pygofer strongly produced posteriorly in lateral view, with apical margin arrow-shaped; dorsal margin deeply concave before posterodorsal margin; disk with long median macrosetae, and with short macrosetae on apical portion and extending anteriorly along ventral margin; pygofer process medially curved, apically acute and extending posteriorly farther than apex. Subgenital plates broad, slightly curved from apical 2/5 to apex, with uniseriate macrosetae and short microsetae on ventral surface. Aedeagus basally broad, with basal ventral lobe articulating with paraphyses; apex dorsally curved. Paraphyses as long as aedeagus, spoon-shaped, apically acute. Connective Y-shaped; stalk short. Style without preapical lobe, apically unciform.
Female abdominal sternite VII, in ventral view, broader than long; posterior margin with concavity medially forming two distinct lateral lobes; lateral margins approximately parallel; surface without striae and with small setae mostly on anterior half. Pygofer, in lateral view, posterior margin with subacute apex; surface with macrosetae clustered apically and extending anteriorly along ventral margin. Second valvulae of ovipositor, in lateral view, moderately expanded beyond basal curvature, shaft narrowing toward subacute apex, preapical prominence small but distinct; teeth distributed from expanded portion to apical portion of shaft, the first tooth triangular and small, followed by larger ones and gradually smaller in apical portion; teeth and dorsal and ventral margins of apical portion of shaft bearing denticles.
Type material. Holotype, male: China, Yunnan Prov., Mt. Gaoligong, Alt. 1800–2400 m, 28 May to 3 June 2009, coll. Yang Zai-hua et Li Bin. Paratypes: 10 males, 13 females, same data as holotype.
Etymology. The specific epithet, cuspidata, is of Latin derivation refers to the cuspidate apical margin of male pygofer.
Remarks. This species is similar to A. heiyuana Li and A. opponens (Walker), but it differs from the latter in that the apex of pygofer is distinctly arrow-shaped, the disk of the pygofer has long median macrosetae and short macrosetae on the apical portion, and the aedeagus has a broad basal lobe in lateral view. In addition, its body is obviously larger than that of A. heiyuana and A. opponens.
