China (Yunnan, Fig. 24). Remarks. By the location and shape of the dorsal lobe, the new species resembles P. c u l t r a t a Vilkamaa & Hippa, 1996. But P. extumida has a distinctively larger intercoxal lobe on the hypopygium than in P. cultrata and the other species. Although the intercoxal lobe of the holotype was partly broken, the size of the lobe could be examined clearly. Etymology. This species is named after its large intercoxal lobe on the hypopygium, from the Latin adjective extumidus, meaning swollen.
