The cranium sincluding frons and clypeus) of males is coarsely and uniformi ypuncta te Fig. 9) while females have a common fronto-clypeat area whicli is glis- te ning and completely impunctate Fig. 8). The frontoclypeal suture is complete-ly obsolete on females. A distinct albeit short) l0th carina is almost always present on the elytra Fig. l0). However, the differen ce belween R. SPeculi fronS and R. crerimen etiS in the presence or absence of the loth carina is not clear-cut. Although ali studied specimens of R. crenipenniS have no l0th carina, the Only R. speculi frons specimen frona Vietnam also lacks this carina. Therefore, in separation of R. Ueculi fronS and R. crenmennis the craniat furface is considered to hethe most decisive Dature. The synonymy of R. dybaSi and R. ScolytoideS is obvious. HoweVer, thethree paralypes of R. sodalis differ frona ali other examined specimens in the sur- face of the head. Based on the absence of long apicat spine on the tibiae and the presence of the loth carina of the elytra they are males of R. SPeculi fronS buttheir clypeus is weakly shining and the coarse punctures typicat for male R. SPE culi fronX are obsolete. Craniat sursace of RhmidandruS must be subject to wear, hecati se these beet les are internat laeders of hard fungat sporocarps. According to the labeis, the second paralype of R. dyhaSi is frona the fame series as the three dubiotis males and this specimen is a se male R. Ueculi fronS without any doubi. We belle ve therefore, that paralypes of R. haSi are specimens of R. SPeculi- frons with abraded clypeu S. Although CHUJO's R. Scolytoides was proved to he synonymous with R. SPeculi fronS, he was the first to recogniZe that the specimens with uniformi ypunctate head and those with the glossy area are conspecific and represent different sexes of the fame species CHUJO l 98 ). R. Ueculi fronS was described froin the Seychelles but iis known range extends hom the Ryukyus and Micronesia to the north and acros f the Indo-Australi an Reaim as far south as Queens land .
