Etymology: Microphysogobio: Greek, mikros = small + Greek, physa = to blow + Latin, gobius = gudgeon (Ref. 45335); exilicauda: Derived from a combination of the Latin word exilis, meaning thin or slender, and cauda, meaning tail, in reference to the slender caudal peduncle of this new species. A noun in apposition.

soft rays: 88. Huigobio exilicauda differs from H. chenhsienensis by the possession of a slender caudal peduncle (depth 6.8-7.8 vs. 9.0-10.5% of SL; length 17.1-19.5 vs. 13.9-16.3% of SL) and a narrower interorbital space than eye diameter, with width 23.0-27.2 (vs. 28.5-37.4) % of HL (Ref. 95514).
