Anisandrus maiche Eggers 1942 : 36 (Synonymy: Pfeffer 1944 ) Diagnosis. Specimens of A. maiche can be distinguished from other members of Anisandrus occurring in North America by the smaller body size (< 2.5 mm ), by the impressed 2nd declivital interstriae and striae, and the raised 3rd declivital interstriae with numerous distinct granules ( Fig. 4 ). It is most similar to A. dispar , also a non-native species in North America , but is easily distinguished by its smaller body size (< 2.5 mm vs.> 3.2 mm for A. dispar ), and the interstriae on the elytral disc which have only one row of seriate punctures ( Fig. 2 ) compared with 2–3 rows of punctures in A. dispar ( Fig. 3 ). Distinguishing Anisandrus from other North American Xyleborina. Hulcr et al. (2007) restored the genus Anisandrus , and included species formerly in Xyleborus , Ambrosiodmus Hopkins and Cyclorhipidion Hagedorn. They state that Anisandrus belongs to a group of genera that are defined by a short, stout body, characteristically flattened antennal club, and, most importantly, the presence of a pronotal mycangial tuft of hairs ( Fig. 1 ). Anisandrus is very similar to Xylosandrus except that the procoxae of Anisandrus are contiguous ( Fig. 8 ), whereas those of Xylosandrus are separated ( Fig. 7 ). In the key to species of Xyleborus north of Mexico by Rabaglia et al. (2006) , species that are now recognized as species of Anisandrus are characterized by having the antennal club distinctly and obliquely truncate with segment 1 corneous (couplet 1), the anterior margin of the pronotum distinctly armed by several coarse serrations, and the body <2.2 x as long as wide (couplet 2) ( Figs. 5, 6 ). The key is modified as follows to include A. maiche with alterations in bold type . An illustrated, online key (http://xyleborini.tamu.edu/keys.php) to North American Xyleborina will be updated to include Anisandrus in the generic key and the following key to the four species in North America .
