Peripsocus Species of the Alboguttatus Group (Psocoptera: Peripsocidae)

Mockford, Edward

work includes material from GRSM; ABSTRACT: The alboguttatus group of the genus Peripsocus is defined on the basis of genitalic features of both sexes and forewing-marking pattern. Ten species are included, seven of which are described as new and are named as follows: P. alachuae, P. australis, P. maculosus, P. minimus, P. mont?cola, P. potosi, P. teutonicus. The forewing marking pattern common, with minor modifications, to most species of the group is departed from by P. mont?cola n.sp., but this species is obviously very close to another included member, P. australis n.sp., as shown by genitalic features of both sexes. The taxonomic treatment is based on examination of 543 adult specimens. The location of the major types of each new species is mentioned in its description. A neotype of P. madescens Walsh is designated. A brief discussion of probable phylogenetic relationships within the species group is included....
