Popis: Kokeshia pengae sp. nov. urn:lsid:zoobank.org:act: 85B2D5C7-6449-4606-BF7E-19DA4285CCBF Figs 15���16, 26H, 29D, 32 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.
