Xyleborus tenuigraphus Schedl, 1953c: 29.
Cyclorhipidion tenuigraphus (Schedl): Beaver and Liu 2010: 24 (as a synonym of C. fukiense).
2.7−3.0 mm long (mean = 2.84 mm; n = 4); 2.5−3.0 times as long as wide. This species is distinguished by the short, steep declivity that is approximately 25% of total elytral length, armed with large tubercles on interstriae 1 and 3, interstriae 2 granulate on apical 1/3; posterolateral margins rounded; and declivital interstriae 1 and 2 setae in 2 confused rows.
This species is a part of a challenging species group consisting of Cyclorhipidion bodoanum, C. distinguendum, C. inarmatum, C. pelliculosum, and C. xeniolum. They can be most readily separated using Smith et al. (2020b) table 1:
declivital interstriae 1 setae
declivital interstriae 2 setae
lateral profile of declivity
declivital interstriae 2 granulate
total length (mm)
2 rows, confused
often on apical third
3 rows, confused
