Abstract

The species of the genus Micrambe Thomson, 1863 (Coleoptera, Cryptophagidae) are revised. Hundred and one species are recognized. Key and figures of the studied species are provided. Following a detailed study of the type material in different entomological collections, the status of taxa is revised and 3 new synonyms are proposed: Micrambe (Micrambinus) schuelkei Esser, 2017a, Micrambe (Micrambinus) yunnanensis Esser, 2017 and Micrambe (Micrambinus) zhejiangensis Esser, 2017 are nov. syn. of Micrambe (Micrambinus) bimaculata (Panzer, 1798). Micrambe duclouxi Grouvelle, 1910 and Micrambe duclouxi (Grouvelle, 1916) are new as synonymy of Micrambe (Micrambe) sinensis Grouvelle, 1910; Micrambe aubrooki Donisthorpe, 1939 is new synonymy with Micrambe hirta Grouvelle, 1908. Micrambe (Micrambe) sinensis Grouvelle, 1910 is resurrected from synonymy with Micrambe (Micrambinus) bimaculata (Panzer, 1798). Micrambe (Micrambe) micramboides (Reitter, 1874) previously known only from Japan is reported here for the first time from Taiwan.

Se revisan las especies del género Micrambe Thomson, 1863 (Coleoptera, Cryptophagidae). Se recogen ciento una especies. Se proporcionan claves y figuras de las diferentes especies estudiadas. Tras un estudio detallado del material tipo en diferentes colecciones entomológicas, se revisa el estado de los taxones y se proponen tres nuevos sinónimos: Micrambe (Micrambinus) schuelkei Esser, 2017a, Micrambe (Micrambinus) yunnanensis Esser, 2017 y Micrambe (Micrambinus) zhejiangensis Esser, 2017 para Micrambe (Micrambinus) bimaculata (Panzer, 1798). Micrambe duclouxi Grouvelle, 1910 y Micrambe duclouxi (Grouvelle, 1916) son ahora sinónimas de Micrambe (Micrambe) sinensis Grouvelle, 1910; Micrambe aubrooki Donisthorpe, 1939 es ahora sinónima de Micrambe hirta Grouvelle, 1908. Micrambe (Micrambe) sinensis Grouvelle, 1910 es rescatada de su sinonimia con Micrambe (Micrambinus) bimaculata (Panzer, 1798). Además, Micrambe (Micrambe) micramboides (Reitter, 1874), previamente citada en Japón, se reporta por primera vez de Taiwán.
