Acanthotomicus flechtmanni Wood 2007: 337 .

The holotype of Premnobius flechtmanni was examined by all authors. By comparison with P. assiduus and P. perezdelacrucei , the pronotum is less elongate (by comparison with the elytra) and its elevated lateral margin is less strongly curved ventrad. The declivity is more abrupt, occupying about 25% of the elytra. There is a small tubercle at the base of declivital interstria 1 and another of similar size on the upper portion of the declivital face. A large tubercle is located near the middle of the declivital crest, subacuminate, and slightly displaced medially from the crest. The male is unknown.
