          Abstract

          Nine species of Parallelodemas Faust are reported from China. In addition to the previously recorded P. impar Voss, we found P. docile Faust, P. vicinum Faust and the following six species newly described herein: P. dimetans sp. n., P. feae sp. n., P. petilum sp. n., P. plumosum sp. n., P. setifrons sp. n. and P. tumens sp. n. Parallelodemas tarsale Voss from Java is transferred to Lepidomyctides Yoshihara and Morimoto (comb. n.). Lectotypes are designated for P. docile, P. imperfectum Faust, P. perfectum Faust, P. tardum Faust and P. vicinum. Several morphological modifications with unknown functions are documented, illustrated and discussed. Males of some species have special setae on rostrum, antennal scape and mesotarsus. A medially notched epistome apparently occurs in both sexes but seems to wear off in females, probably during the preparation of oviposition sites. The mandible is unusual in having a convex, edentate inner face and incisor-like structures on the outer face.

              Ritual Jousting by HornedParisoschoenus expositusWeevils (Coleoptera, Curculionidae, Baridinae)

              Males of the weevil Parisoschoenus expositus use their prothoracic horns as weapons in stylized battles with other males over females that are drilling oviposition holes in palm leaves. The unusual sheath-like structures that penetrate deep into the male prothorax function to receive the horns of opponents during battles. Horn size is dimorphic with respect to body size, and small and large males also differ behaviorally. Small males that have mated with a drilling female are sometimes able to impede a large male's access to the female until after she has oviposited, but they are not able to take over females from larger males.
