Gastroserica nigrofasciata sp. n. is in habitus very similar to Gastroserica marginalis (Brenske, 1897). It maybe differentiated from Gastroserica marginalis by the colour of elytra and dorsal surface, the presence of two long lateral apophyses at the apex of phallobasis, and the shape of parameres.
From the Latin words “nigro-” and “fasciata” meaning black stripes.
