Reticulum trispinosum sp. nov.

(Figs. 9–17)

Size. Length of body to apex of forewings: Male 4.5–4.6 mm, female 4.5–4.7 mm.

Description. Yellow to fuscous with well expressed brown or black pattern. Vertex with six black spots on fore margin and a broad black transverse band between ocelli interrupted medially (Fig. 9). Face with frontoclypeus yellow, with well developed and often partly merged dark-brown arched lines; anteclypeus, genae and lorae mostly brown (Fig. 10). Pronotum yellow with some vermiculate brown flecks. Mesonotum pale yellow, with two triangular marginal spots and two pale brown dots anterior to scutellar suture, and two triangular marginal spots posterior to it, brown (Fig. 9). Forewings pale yellow hyaline with variable brown irroration; spot on apex of claval veins and on transverse costal veins, dark brown (Fig. 11). Female with abdominal sternite VII 3 times as long as abdominal sternite VI, caudal margin medially produced posteriorly with a median notch (Fig. 15).

External features as in generic description.

Male pygofer longer than broad in lateral view, with 4-branched process on inner surface arising near dorsal margin (Fig. 12). Style elongate, apical process short, tapered to acute apex and curved laterally; lateral lobe weakly developed, with a few fine setae (Figs. 17). Aedeagal shaft tubular and elongate, curved caudally, truncated at apex, an elongate, dorsally directed lateral lamellate processes arising basally extending dorsally near apex of shaft (Figs. 13, 14).

Type Material. Holotype %, China, Sichuan Prov., Batang, Zhubalong, 2450m, 11–10 July 2001, Sun Qiang, at light. Paratypes: China, 3 %, 2Ψ, data as for holotype.

Distribution. China (Sichuan).

Diagnosis. This species differs from other species of the genus in having the dorsal process of the pygofer 4-branched and the basal processes of the aedeagal shaft long, almost extending to shaft apex. It also differs from Reticulum lanceolatum sp. nov. in having the aedeagal shaft with a basal pair of processes curved caudally.

Etymology. The name of the new species refers to the 3-branched process on the inner surface of the pygofer side.
