Gall: the gall (Fig. 11A) is unilocular on twigs, nearly spherical, 8–10 mm in diameter, slightly flattened basally, with a smooth surface, lacking pubescence, yellowish with concentric circular red-brown lines, apically reddish-pink. The gall stays soft when mature, but not fragile. Larval chamber ovate, 1.4 × 1.8 mm, with thin walls (0.16 mm), surrounded by a sponge-like tissue, located in the centre of the gall. Exit hole usually located laterally. There is always a longitudinal crack in the bark where the gall is inserted.

Host plant: Quercus acutifolia, Q. castanea, Q. crassifolia and Q. crassipes (section Lobatae within Quercus).

Biology: only known from an asexual generation.

Distribution: currently known only from Mexico. Originally recorded only from the state of Michoacan. New records from Oaxaca, Puebla and Mexico states added here extend the distribution of this species.

Remarks: K. doctorrosae can be easily distinguished from the other known species of Kokkocynips by the regular well-marked reticulate sculpture on the metasomal terga. Congruent with the morphological similarity of both adults and galls, this species is sister to the Nearctic species K. imbricariae in the multi-locus phylogenetic analysis (Fig. 1), and forms a close cluster with K. imbricariae and K. difficilis based on cytb distances (all just over 5% divergent; Table 1).
