Type of genus Bostrichus binodulus Ratzeburg, 1837 . Diagnosis This genus can be diagnosed by the emarginated eye, by the coneshaped antennal club with slightly recurved sutures, and by the rounded lateral margins of the pronotum. Female Eye emarginated. Frons simple with no extensive sculpturing or of vestiture. Cuticle behind eyes reticulated or aciculated. Antennae with five funicle segments. Antennal club conical, sutures recurved or straight. Pronotum armed with four to six marginal asperities, with the median of the margin slightly projected. Pronotal declivity with more than 30 asperities leading to a slightly elevated summit. Lateral margins of the pronotum rounded, hypomeron with mostly hair-like setae, sometimes with a small number of bifurcating setae. Elytra broadly convex, sometimes with interstriae 4 slightly raised. Vestiture comprised of hair-like or scale-like interstrial bristles and ground vestiture. Male Similar to female except anterior margin of pronotum slightly more projected. Elytral interstriae 4 sometimes with small tubercles or spines near declivity. Penis apodemes of a similar length to penis body, separated at apex. Tegmen open dorsally. Median ventral face of tegmen without apodeme or with only a slight projection. Spiculum gastrale with a fork, and of similar thickness to the penis apodemes. Basal sclerites visible. Distribution East Asia , Europe, North Africa, North America. Remarks Fifteen species known. Found primarily on Salix and Populus (Salicaceae) , and Alnus (Betulaceae) . Larvae develop communally for the first instar, then independently to complete development ( Furniss 2004 ). Type material examined Holotype of Trypophloeus populi Hopkins, 1915 (USNM) ; holotype of Trypophloeus salicis Hopkins, 1915 (USNM) ; holotype of Trypophloeus concentralis Hopkins, 1915 (USNM) . Included species Trypophloeus alni Lindemann, 1875a: 136 . = Trypophloeus holdhausi Wichmann, 1912: 186 (syn: Balachowsky, 1949 ).

Trypophloeus discedens Palm, 1950: 142 . = Trypophloeus palmi Hansen, 1956: 183 (syn: Süda, 1996 ). Trypophloeus grandis Schedl, 1964a: 99 . Trypophloeus granulatus ( Ratzeburg, 1837: 164 ) ( Bostrichus ) . = Cryphalus granulatus var. tredli Hagedorn, 1904: 232 (unavailable name). Remarks: Cryphalus tredli Reitter, 1908 was erroneously listed as a synonym of Trypophloeus granulatus , without the original genus in Wood and Bright (1992) (p. 845), in addition to its correct entry as a valid species in Hypothenemus . Cryphalus granulatus var. tredli Hagedorn, 1904 was described without locality data, so cannot be considered even a subspecies. Trypophloeus klimeschi Eggers, 1915: 188 . Figure 21.
