Xyloctonus stenographus Schedl, 1961a, synonymy by Menier (1974) . Type material. Lectotype , X. aethiops : Madagascar, Ankorika [-12.24, 49.36], K. E. Schedl, 1951 [MNHN]. Holotype of X. stenographus : Madagascar, Perinet [-18.93, 48.41], 28. XI. 1952, Dr. K. E. Schedl [MNHN]. Diagnosis. Length 1.3-1.6 mm, 2.0 x as long as wide, colour dark brown; vertex with faint (false) pars stridens; antennal club with two visible procurved sutures; anterior margin of pronotum with four raised teeth, median teeth longest; elytral interstriae 9 curves before apex and continues to elytral suture; elytral interstriae elevated, flattened, carinated on and near declivity only; scutellar shield transversely oval; elytral suture straight. Ventrite I swollen on median third of its posterior margin, ventrite II with four spines along the posterior margin. Distribution. Madagascar. New record. Madagascar, Andasibe, Mantadia National Park [ -18.861 , 48.447 ], 900 m alt. 15 May 2015, ex Uapaca twig, B. Jordal, leg. [ZMUB]. Biology. Two collections from known host were both in the same plant family Phyllanthaceae : Wielandia mimosoides (originally in Savia ) ( Schedl 1977 )) and Uapaca sp. This is the only Xyloctonus that cut their egg tunnels parallel to the grain of the wood. Three broods with larvae were dissected from a thin twig of 1 cm thickness and were without parents present. Brood size ranged between 21 and 28 (n = 3).
