Afissa quindecemguttata Dieke, 1947: 126 . Type locality: China, Szechwan Prov., West of Yachow. Afidentula quinquedecemguttata: Pang & Mao 1979: 122 (unnecessary emendation). Fürsch, 1984: 338; Ren et al. 2009: 252. Afidentula quindecemguttata: Jadwiszczak & Węgrzynowicz 2003: 24 .
Diagnosis. This species is most similar to A. himalayana in general body shape and coloration. It can be separated from that species by having smaller body, the head and at least disk of pronotum black, and abdominal postcoxal lines incomplete. Moreover, the lack of a distinct groove behind the anterior raised border of the mesoventrite and behind the raised border of the metaventral process distinguish A. quindecemguttata from A. himalayana .
Description. Length 4.9 mm; TL/EW = 1.38; PL/PW = 0.47; EL/EW = 1.2; EW/PW = 1.64. Body (Figs. 103, 164) elongate oval, convex; dorsum covered with short setae. Head black, mouth parts yellow, pronotum black with posterior angles or whole lateral margins yellow, prosternum, meso- and metaventrite black, scutellum brown. Elytron orange with seven black maculae on each elytron arranged as 2–3–1–1. Anterior two spots large, oval, not touching margins of elytra but median spot placed close to suture; second row of spots with one semicircular spot touching suture, second spot large, oval, in middle of elytral disk, third spot large, oval, touching outer margin of elytra; third row in about apical fourth consisting of one large transverse macula appearing like two partly fused spots; posterior spot small, placed on elytral apex. Coxae black, trochanters brown, profemora yellow, mid- and hind femora black with apical fourth brown, tibiae and tarsi yellow. Abdomen black.
Labrum very small, transverse. Labium with second palpomere distinctly broader apically than terminal one at its base, about 1.25 times as long as terminal palpomere (Fig. 104).
Prosternal process about 0.31 times as wide as longest procoxal diameter and about 1.20 times wider than prosternum in front of coxae in narrowest place (Fig. 105). Mesoventrite (Fig. 106) with anterior edge with complete raised border but without distinct groove behind it; mesoventral process 0.55 times as wide as coxal diameter at the same position, with weak tubercle medio-posteriorly. Lateral margins of elytra very narrow and visible from above almost throughout. Epipleuron (Fig. 103) about two times broader than metepisternum. Metaventrite with intercoxal process bordered and raised, without groove behind it; metaventral postcoxal lines complete, somewhat descending laterally.
Legs long with apices of femora slightly protruding from outer margin of elytral epipleuron; trochanters scarcely produced on inner margin, almost simple.
Abdominal postcoxal lines incomplete (Fig. 107), reaching posteriorly about ¾ length of ventrite 1; apical margin of male ventrite 5 truncate, ventrite 6 narrowly emarginate (Fig. 109) medially at apex, tergite VIII rounded (Fig. 108).

Mesoventrite (Fig. 118) with anterior edge with complete raised border and with distinct groove behind it; mesoventral process at least as wide as mesocoxal diameter. Lateral margins of elytron narrow and visible from above at least along 4/5 of elytral length. Epipleuron (Fig. 116) broad, about 3.5 times broader than metepisternum. Metaventrite with intercoxal process broadly bordered and raised with distinct groove behind it and also behind postcoxal lines; metaventral postcoxal lines complete, straight laterally. Apices of femora not protruding from outer margin of elytral epipleuron.
Abdominal postcoxal lines incomplete, reaching posteriorly about 2/3 length of ventrite 1; apical margin of female ventrite 5 somewhat sinuate (Fig. 119), sternite and tergite VIII weakly rounded (Figs. 120, 121).
Female genitalia (Figs. 122–124). Proctiger (TX) rounded; coxites round-oval.
