Taxonomic history

Xyleborus eupatorii Eggers, 1940: 140.

Xylosandrus eupatorii (Eggers): Schedl, 1964c: 213.

Diagnosis

2.0−2.3 mm long (mean = 2.12 mm; n = 5); 2.22−2.3 times as long as wide. This species can be distinguished by its moderate size; elytral disc gradually curving toward declivity, appearing rounded; posterolateral margins of elytra carinate to interstriae 7; declivital face with six punctate striae; declivital interstriae uniseriate granulate, with erect hair-like setae longer than the width of two interstriae; pronotum as long as wide, pronotum from dorsal view rounded (type 1) and lateral view basic (type 0), summit at midpoint, basal half smooth, shining, sparsely minutely punctate; and sparse mycangial tuft on the pronotal base.

This species is nearly identical to X. germanus and is most readily distinguished by the pronotum that is as long as wide and pronotum base with sparser more disperse setae.
