Taxonomy: We note that the original spelling of the specific name by Stebbing (1914) was schlichii, although the species has generally been referred to in later publications as schlichi (e.g. Beeson 1930, 1961, Wood & Bright 1992, Maiti & Saha 2004, Hulcr & Cognato 2013). Hulcr and Cognato (2013) have synonymised Amasa striatotruncata (Schedl) with A. schlichii. As with A. glabra (see above), we prefer to keep the species separate pending further studies, and have not included the distribution of A. striatotruncata in the list above. A. striatotruncata can be distinguished from A. schlichii by the following characters (A. striatotruncata c haracters listed first): elytral declivity weakly convex, the upper part not impressed, sutural interstriae very slightly raised close to the apex, bearing a few small tubercles, interstriae 2–3 on declivity without tubercles, smooth and shining vs elytral declivity more strongly convex, sutural interstriae strongly raised in apical half of declivity and bearing much stronger tubercles; interstriae 2–3 on declivity usually granulate near apex and rugulose.

Biology: Browne (1961a, as Xyleborus uniseriatus Eggers) suggests a strong preference for Fagaceae, but the species seems to be polyphagous (Beeson 1961, Beaver & Browne 1979).
