Abstract
We present further information on the very diverse Chinese fauna of soldier beetles. Four new species of Lycocerus hickeri species-group are described, L. mainriensis sp. nov., L. guangxiensis sp. nov., L. rufipennis sp. nov. and L. acutiapicis sp. nov., and L. nigrobilineatus Pic, 1916 is transferred to this group and redescribed. All species are illustrated with habitus photos of both sexes, aedeagi of males, abdominal sternites VIII and reproductive systems of females. Two secondary homonyms are replaced. L. hickerimimus nom. nov. is proposed as a replacement name for L. sichuanus Y. Yang et X. Yang, 2014, which is preoccupied by L. sichuanus (Wittmer, 1995), and L. parahickeri nom. nov. for L. hubeiensis Y. Yang et X. Yang, 2014, not L. hubeiensis (Švihla, 2004). Distribution data are provided for the previously known species, and a map is presented for this species group. A key for identification of the species of this species-group is updated.
