Cyclorhipidion Hagedorn, 1912

Cyclorhipidion Hagedorn 1912: 355 .

Terminalinus Hopkins 1915: 10 . Synonymy by Wood and Bright (1992: 697).

Kelantanius Nunberg 1960: 621 . Synonymy by Wood (1986: 83).

Notoxyleborus Schedl 1934: 84 . New synonymy.

The genus Notoxyleborus Schedl, 1934, with the type species Notoxyleborus kalshoveni Schedl, 1934, is currently placed as a synonym of Xyleborus Eichhoff, 1864 (Alonso-Zarazaga and Lyal 2009; Wood 1986; Wood and Bright 1992). The female lectotype (in Naturhistorisches Museum) was examined and found to belong to Cyclorhipidion Hagedorn, 1912 . The antennal club is type 5 (not type 2 as in Xyleborus); the pronotum is rounded (type 1) in dorsal view (not type 2) and type 5 in lateral view (not types 0 or 7); the elytra lack costae or carinae, and the punctuation is minute, very dense, and confused, with striae and interstriae not easily distinguishable (not seriate-striate); the posterocoxal process is not swollen. These and other characters clearly place the type species in Cyclorhipidion and not Xyleborus . Therefore, we propose Cyclorhipidion kalshoveni (Schedl, 1934), new combination .
