Discussion. Waterhouse (1877: 12) described S. plagiata as a species of Stenaspis . According to his description, S. plagiata is elongate, parallel-sided with a thorax that is almost twice as broad as long, convex, closely rugulose with five nitid black impressions on the disc, and side angulate in middle. The elytra are scarcely narrower than the thorax. Based on the photographs of S. plagiata ( Bezark 2020, id: 18552 and 18553), the pronotum is as wide or slightly wider than the elytra at the humeri, and the disc is densely, contiguously punctate with a black glabrate macula post-medially in middle and with six black, glabrate maculae on either side, a pair ante-medially, and another pair post-medially on each side of the middle macula, and another pair of maculae on each side in a depressed area adjacent to the lateral tubercles (e.g., Fig. 160 a–d ). The elytra are coarsely, confluently punctate. These characteristics of S. plagiata ( Fig. 155, 158 ) are shared with Crioprosopus wappesi Eya ( Fig. 156, 159 ) and Crioprosopus nieti Chevrolat ( Fig. 157, 160 ), and the overall resemblance of S. plagiata is strikingly similar to these two species of Crioprosopus . The four Stenaspis species examined (i.e., S. castaneipennis , S. solitaria, S.

superba and S. verticalis ) all have the pronotum narrower than the base of the elytra at the humeri, and discs that are more sparsely and irregularly punctate. Furthermore, S. plagiata has the signature impression in the basal half of the scape found in Crioprosopus , and canaliculations on the dorsum of antennomeres III and IV, which are evident from the photos ( Bezark 2020, id: 18552, 18553). Therefore, Stenaspis plagiata is transferred to Crioprosopus as a new combination, Crioprosopus plagiatus (Waterhouse) , new combination, although the actual specimen from the British Museum of Natural History was not examined.

I would like to provide an interesting side note concerning the name or word plagiatus or plagiata that appears in the Latin description of S. solitaria (e.g., Thomson 1864: 208) or as a species name of a damselfly (e.g., Lestes plagiatus (Burmeister)) . As described by Fliedner (2006), plagiatus does not translate as “kidnapped” as defined in a Latin dictionary but the etymology of the name “ plagiatus or plagiata ” is from Late Latin “ plagio- ”, from Ancient Greek πλάγιος (plágios or “oblique, sideways or transverse”) and the Latin suffix -atus (marked with or equipped with) or provided with oblique markings. In the case of the damselfly L. plagiatus it refers to the conspicuous white band on either side of the thorax from the base of the rear wings to the middle pair of legs. For C. plagiatus (Waterhouse) it refers to the presence of transverse yellow markings on the elytra. Another example is the yellow tomentose spots in a species of Staphylinidae ( Sphaerobulbus biplagiatus ) ( Smetana 2006). Thomson (1864: 208) writes “Prothorax dorso vel plagiatus, vel tuberculatus, vel inaequalis” describing Smilecerus LeConte (i.e., S. solitaria ), which appears to be describing the anterior angle and lateral tubercles of pronotum as “prothorax ridged and oblique, and tuberculate, and unequal.”

The following is the revised couplets to key for the species of the genus Crioprosopus :
