Xylosandrus subsimilis (Eggers): Wood and Bright, 1992: 800.

Diagnosis

2.5−2.9 mm long (mean = 2.64 mm; n = 5); 1.79−2.0 times as long as wide. This species can be distinguished by its moderate size; elytral disc flat, longer than declivity; declivital face steep, abruptly separated from disc; elytra appearing truncate; posterolateral margins of elytra carinate to interstriae 7; declivital face with four apparent granulate striae (striae 5 short, converging with striae 4 forming a loop); declivital face flattened, depressed below declivitial margins; declivital striae and interstriae setose, setae recumbent, thick, less than ½ width of an interstria; interstriae granulate, granules multiseriate, confused strial granules at least two times larger than those of interstriae; pronotum longer than wide, from dorsal view conical frontally (type 6) and lateral view taller (type 2), summit at basal quarter, basal quarter shagreened, dull, densely punctate; and broad, dense mycangial tuft on the pronotal base.
