Description. Size. Male 4.7–4.9mm.
General color orange brown. Vertex orange yellow, with visible creamy depression on each side of coronal suture (Figs. 2, 3). Eye dark (Figs. 1–4). Ocelli grayish surrounded with whitish yellow (Figs. 3, 4), coronal suture reddish brown (Figs. 2, 3). Frontoclypeus beige except basal part with irregularly orange patch in middle, anteclypeus and genae greyish (Fig. 4). Pronotum mostly orange brown, anterior margin and arcuate area behind eyes orange (Figs. 2, 3). Scutellum centrally with a big roundish black spot anteriorly, basal angle with a hypodermal triangle patch on each side, scutoscutellar sulcus black brown (Figs. 2, 3). Forewing subhyaline, Abdomen black, legs sordid yellowish.
Basal sternal abdominal apodemes reaching anterior margin of segment 5 (Fig. 7). Male pygofer in lateral view with ca. 9 rigid setae on each side of lobe, ventral appendage fairly developed, bending upwards in middle, apically branched, the dorsal branch long and robust which is furnished with tiny denticles along ventral margin in apical half, the ventral branch short with pointed apex (Figs. 5, 10, 11); dorsal bridge nearly third of the total length of pygofer (Fig. 6). Anal tube process reaching apical 2/3 of height of pygofer, branched near apex, the dorsal branch flake-shaped and less pigmented, the ventral one well sclerotized, curved cephalo-ventrad and gradually narrowing, apex rounded (Figs. 5. 10, 12). Subgenital plate broad in basal third, with 4 fairly long and stout setae forming the basal group, 18-20 lateral macrosetae starting at 1/4 distance from base arranged in two rows somewhat truncated terminally, apical setae in one row and spine like, 31-33 short marginal microsetae occupying almost half length of anterior margin, fine setae in one row in basal half followed by irregular 4 rows in distal half (Figs. 5, 10, 16). Paramere sinuate, apical half narrowed, bearing 4 prominent teeth in dentifer (Figs. 5, 10, 17). Aedeagal shaft tubular, triangular in cross-section, broad at base and narrowing cephalad in profile, with pair of basal process directed laterad, gonopore terminal, preatrium broad, trough-like, nearly twice as long as shaft (Figs. 13, 14). Connective broad, apical margin emarginate medially (Fig. 15).
Etymology. The specific epithet is an adjective derived from the Latin ‘ stictus ’ with the feminine termination ‘ -a ’, referring to the black spot of the scutellum.
Distribution. Known only from the type locality in Sichuan Province in southern China.
