Atkinsoniella longiuscula Feng & Zhang sp. nov.

( Figs. 1 A–D, 2)

Description. Crown bright orange, anterior portion of pronotum and scutellum bright orange or yellow in dorsal view; ocelli white-transparent with narrow border; a small black spot at apex of head and basal margin median; three big black spots located on anterior portion of pronotum; abdomen bright orange in ventral view; forewing bright orange at base, white-transparent in the rest; face, legs bright orange.

Head moderately produced with anterior margin broadly rounded in dorsal view; ocelli located in concavities and before a line between anterior eyes, crown convex between ocelli; lateral clypeal sutures extending onto crown but not attaining ocelli; clypeus flattened medially with muscle impressions weak; pronotum prominently convex and wider than head, disk dorsum without sculpture and lateral margins divergent posteriorly, with anterior margin convex and posterior slightly concave in the median; scutellum convex before and behind transverse depression; forewing with four apical cells, base of the second and third cells almost aligned transversely.

Male abdominal second sternal apodemes short, not attaining first conjunctiva behind their origin. Male pygofer produced posteriorly, posterior margin narrowed, with macrosetae on posterior portion; pygofer processes arising basiventrally on each side, folding near apex in caudal view, extending posteriorly; plates with macrosetae uniseriate, with long microsetae near lateral margin and entire ventral surface in apical half; connective ‘Y’- shaped, extending posteriorly farther than midlength of style but not as far as style apex; style slender, with a hook in the apex; aedeagus wide only significantly narrowing anteapically in lateral view; paraphysis slender and much longer than aedeagus, dorsally curved abruptly apically and articulating with aedeagus.

Measurement. Length of male 9.0–9.3mm.

Material examined. Holotype: ♂, China, Sichuan Province, Emei Mountain, 15 July 2011, coll. Zhang Huining; Paratype: 2 ♂♂, China, Sichuan Province, Emei Mountain, 15 August 2006, light trapped, coll. Zhang Tiantao.

Remarks. This species is similar to A. punica Yang & Li, 2002 in appearance, but the latter has plates without uniseriate macrosetae and the aedeagus is trianglular in lateral view. It is also similar to A. flavipenna Li et Wang, 1992 , but differs in having the forewing bright orange at the base but otherwise white-transparent and the aedeagus wide, only significantly narrowing anteapically in lateral view.

Etymology. This new specific epithet is derived from the Latin word “longiusculus” referring to the paraphysis being slender and much longer than the aedeagus.
