Ossuaria sichuanensis sp. nov.

Figs 1–9, 21–22, 25–27.

Body ( Figs 21, 22 ) yellow. Vertex with sordid whitish patches at anterior margin and along coronal suture. Pronotum with sordid whitish patches at anterior margin and in center. Scutum with brown medial longitudinal stripe, basal triangles brown. Scutellum dark brown. Forewing ( Fig. 25 ) with brochosome field, c and r cells, 3rd and 4th apical cells whitish; brown patch on clavus, absent in some specimens.

Male genitalia. Pygofer (Fig. 2) with several short rigid microsetae situated on hump at central part of distal half of lobe. Paramere (Figs 3, 5, 6) straight basally, short and thick apically. Aedeagal shaft (Fig. 8) slightly concave apically, strongly concave near gonopore at subapex laterally; apex expanded dorsad in lateral view; with pair of subapical processes not extended to shaft apex in ventral view.

Measurement. Length of male 3.07mm, female 2.87mm.

Material examined. Holotype male, China, Sichuan Prov., Mt. Emei, Wuxiangang, 600m, 2 Nov. 1999, coll. I. Dworakowska. Paratypes: 6 males, 25 females, same date as holotype; 1 female, Sichuan Prov., Mt. Emei, Qingyinge, 600m, 2 Nov. 1999, coll. Qin Daozheng.

Remarks. The new species is similar to O. agara Dworakowska and O. yunnanensis sp. nov., but can be distinguished by the shorter and thicker apex of the paramere, the aedeagal shaft with the apex and subapex concave and the absence of a lateral spine at the base of the subapical process (Figs 3, 5–8).

Etymology. The new species is named after its type locality “Sichuan”.
