Description. Length 4.5–6.0mm. Body elongate. Integument black. Vestiture consisting of tufts of black setae and some paler scattered setae; pronotum with several spots of white setae and an elongate spot before the scutellum; elytra each with a patch of brownish white setae basolaterally and one common patch of transverse white setae apically. Rostrum flattened, width>2.0X width of interocular distance, wider than long but not longer than head. Antennae slender, not reaching pronotal base. Eyes protruding and oblique, finely faceted, with more than 26 rows of facets across the maximal width. Pronotum about as wide as long; disc coarsely, unevenly punctate, surface either convex or with paired, juxtamedial depressions; lateral carina ending in a low ridge; transverse carina antebasal, angulate medially with angle directed forward and obtusely bent laterally. Elytral width slightly>1.0X pronotal width, length 2.0X pronotal length; striae with rows of coarse, deep punctures.

Diagnosis. Goniocloeus bimaculatus can be distinguished by the short, flat rostrum that is more than twice the width of the interocular distance, pronotum with several small patches of yellow setae, elytra with a patch of whitish-brown setae basolaterally and a common, transverse patch of white setae apically, by having the fusion of the rostrum with ventral side of the head indicated by a transverse groove or an abrupt angle, and by the finely faceted eyes with more than 26 rows of facets across maximal width.

Natural history. Valentine (1998) collected this species on Biscogniauxia spp . fungus on a winterkilled sugar maple, on fungi in the genera Xylaria and Diatrype , under bark of dead oaks ( Quercus spp. ), and on Osage orange ( Maclura pomifera ).

Phenology. No specific data for Wisconsin specimens.

Collecting methods. This species is likely collected by from under bark of dead hardwood trees that are infested with fungi in the genera Biscogniauxia , Xylaria and Diatrype .
