Diagnosis. A Baldorhynchus of medium or large size belonging to the B. blesioi group with elytra ogival or elongate-oval. This species is recognisable by the medium-large body size and the pronotum strongly narrowed at the base. Punctation of pronotum is small, regularly arranged, shallow and quite sparse. Punctation of the elytra small, regularly aligned and superficial. Total length: 4.80–5.20 mm. Elytra with length/width ratio 1.93–2.00. Pronotum length 0.90–1.00 mm with length/width ratio 1.16–1.25.

Description. See Osella (1968) and figures hoc opus.

Holotype. Female. Total length: 4.80 mm. Scape length: 1.00 mm; funicle length: 1.00 mm. Scape length/ funicle length ratio: 1.00. Funicle with club ratios: 13: 7: 6: 7: 5: 6: 4: 26 (club). Vestigial eyes not present. Vertex width/mesorostrum width: ratio 2.00. Pronotum ratio: 1.19 (length: 0.95 mm, width: 0.80 mm). Elytra ratio: 2.00 (length: 3.00 mm, width: 1.50 mm).
