Diagnosis

The male of K. pengae sp. nov. is similar to K. oroszi , but can be distinguished from the latter species by an obviously large body size 1.20‒1.29 mm, whereas 1.04 in K. oroszi ; process of left hemitergite VIII flagelliform, produced from left margin of left hemitergite VIII, whereas in K. oroszi , process of left hemitergite VIII flagelliform, produced from posterior margin of left hemitergite VIII; apical portion of phallus short, slightly curved, forming about a half coil outside of pygophore, whereas in K. oroszi , apical portion of phallus longer and curved, forming about one incomplete coil outside of pygophore.

Etymology

The species epithet is derived from and dedicated to Prof. Yanqiong Peng (Key Laboratory of Tropical Forest Ecology, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, China), appreciating her kind help during our field works in Xishuangbanna and recognizing her contributions to the study of co-evolution of fig and fig wasps.

MACROPTEROUS. Small sized (about 1.20‒1.29 mm).

COLORATION. Body light brown to brown, appendages yellowish brown ( Fig. 15A–C ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.63–0.74 × length of maximum width across eyes.

THORAX. Humeral width 1.62‒1.84 × as long as middle length of pronotum. Venation of forewing in accordance with general pattern of genus. C+Sc, R+M, R and basal portion of 1An darker than wing surface, other veins slightly darker than wing surface ( Fig. 26H ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical. Tergite VIII subdivided into two hemitergites, left hemitergite VIII with slender needle-shaped process, curved from base ( Figs 15D– E, G , 16A, C ). Basal portion of process with sparsely microtrichia. Right hemitergite VIII with long, triangular posterolateral portion projecting posteriad, bearing microtrichia at apex ( Figs 15E–F , 16B ).

GENITALIA. Pygophore simple, asymmetrical, dorsal surface with dense microtrichia, posterior area with relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 15E , 16D‒E ) with broadly rounded laminate extension directed dorsal near base, and with flattened and tapering distal projection, and curved inward; right paramere ( Figs 15E , 16F‒G ) with flattened, round and relatively slender distal projection. Apical portion of phallus ( Figs 15D‒E , 16H ) tubular, short, forming about ½ coil outside of pygophore.

Female

Unknown.

Distribution

Yunnan Province, China ( Fig. 20 ).
