    Description

    Schizosthetus lyrifomis (McGraw and Farrier, 1969) is redescribed for all inslars, emphasizing ontogenetic changes in sensillar and gland patterns of all body parts This approach allows recognition of some previously unreported patterns. Major positional shifts of lyrifissures over ontogeny appear correlated with the formation of the peritremes, and some setae of leg tarsi II-IV are unexpectedly variable in both shape and presence. In addition, the two remaining members of the genus are briefly described, with a new diagnosis for the genus. Schizosthetus is strongly associated with bark beetles, with a geographic range matching that of their most common hosts.
