Popis: Premnobius perezdelacrucei Petrov & Atkinson Fig. 4 C, D Premnobius perezdelacrucei Petrov & Atkinson, 2018: 42. Gnathotrupes megapunctatus Bright, 2019: 410. New synonymy. Similar species. Among the American species this most closely resembles P. assiduus. Diagnosis. Length 2.45 mm, 4 as long as wide (Petrov & Atkinson 2018: 42). Very slender, with proportionately elongate pronotum. Frons shining, weakly reticulate, with sparse setae. Pronotum elongate, 80% as long as elytra; anterior margin rounded, weakly elevated with small asperities; summit located about 25% of length from anterior margin. Disc smooth, shining, with shallow, sparse punctures; vestiture a mixture of taller and shorter erect setae. Elytral striae not impressed, interstriae 2 width of striae; vestiture of erect setae, length greater than width of interstriae, mostly uniseriate, about twice as long at base of declivity. Declivity occupying posterior 33% of elytral length. A raised posterolateral crest present from interstria 4 to apex, transition gradual above. Declivity with a small, sharp tooth near base on interstria 3, displaced mesally from declivital margin; a laterally flattened, apically rounded projection on crest about 2/3 of the distance to apex, its basal length greater than its height.
