The three subgenera of Paratyndaris (Knulliella, Paratyndaris, and Waltersia) are separated by structural features including antennal form, pronotal shape, and elytral characteristics. Within Waltersia, P. knulli is one of four species alongside P. barberi, P. equihuai, and P. trilobata. Specific distinguishing characters for P. knulli would require reference to the original description or revision.

Appearance

Small metallic wood-boring . As a member of the Paratyndaris, likely exhibits the characteristic compact, somewhat chunky body form typical of the group. The subgenus Waltersia, to which this belongs, is distinguished by specific morphological characters from other subgenera (Knulliella and Paratyndaris). Detailed external would require examination of or original description.

Habitat

Associated with dead . Based on -level patterns, likely inhabits dry or semi-arid regions where plants occur. The related P. prosopis occurs in similar on hackberry and mesquite in Oklahoma and Texas.

Distribution

Central America and North America. Specific documented localities not detailed in available sources, but the subgenus Waltersia has southwestern distribution patterns.

Ecological Role

As a wood-boring , contributes to decomposition of dead woody material. Larval feeding in dead branches facilitates in forest and woodland .
