Type material.

Syntypes (NHMW, 1; examined) and (MIIZ, 1; not examined) ( Węgrzynowicz and Mokrzecki 1996). See remarks.

Diagnosis.

2.1 mm (n = 1), 3.5 × as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivital interstriae 2 convex, declivital interstriae 1-3 unarmed, elytral apex deeply emarginate, and declivity steep, occupying less than posterior 40% of declivity.

Similar species.

Distribution.

Panama ( Panamá), Peru ( Huánuco), Venezuela (Barinas).

Biology.

Unknown.

Remarks.

Eichhoff (1878) described the species from an unspecified number of specimens. Schedl (1979) apparently presumed that the specimen of X. cuneatus in his collection to be a holotype under the assumption that the species was described from a single specimen. This is not the case, as an additional syntype is in MIIZ along with several other Eichhoff types ( Węgrzynowicz and Mokrzecki 1996; Cognato et al. 2019; Smith et al. 2019b). Both specimens are therefore syntypes.

The species was described from specimens collected in Varinas [sic, Barinas], Nova Grenada. The species was listed from Colombia (Wood and Bright 1992; Wood 2007) but we were unable to find specimens definitively from this location (Wood 2007). The type specimens were likely collected from Barinas, Venezuela.
