A revision of the Entisberus group (Hemiptera: Heteroptera: Rhyparochromidae)
The genus Entisberus Distant, 1903, and related genera are revised. Neoentisberus Scudder, 1968, syn. nov., is synonymized with Retoka China, 1935, and Entisberus gibbus Zheng, 1981 is transferred to Retoka, which results in the following new combinations: Retoka brincki (Slater, 1979) comb. nov., R. callosa (Scudder, 1968) comb. nov., R. esakii (Slater & Hidaka, 1958) comb. nov., R. gibba (Zheng, 1981) comb. nov., and R. indica (Scudder, 1968) comb. nov. Five new species belonging to the Entisberus group (defined here as a group containing the genera Entisberus and Retoka) are described: Entisberus bergrothi sp. nov. (Philippines), Retoka hirsuta sp. nov. (Philippines, Borneo), R. curvipes sp. nov. (Malaysia), R. stysi sp. nov. (Vietnam), and R. paraminuta sp. nov. (India: West Bengal). A key for the identification of species in the Entisberus group is presented, and new distributional data of previously described species from India, China, Taiwan, Vietnam, Malaysia, Indonesia and New Guinea are given.
