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 .

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 View FIGURES 103 – 115 ).
