Crypticerya rileyi group

This group includes five Nearctic species: C. colimensis , C. morrilli , C. rileyi , C. tabernicola and C. townsendi . The adult females of C. rileyi and C. colimensis form long ovisacs and the adult female of each of the remaining three species forms a marsupium. Crypticerya colimensis and C. rileyi have identical pores and setae that form the ovisac band, but differ by the number of cicatrices ( C. colimensis has a single cicatrix, C. rileyi has three cicatrices). Crypticerya morrilli and C. tabernicola have similar derm pores, mostly with a bilocular centre, whereas C. townsendi has more pores with trilocular centres. These three species also differ by the shape of the marsupial band. Although the marsupial band of all three species forms a completely scle- rotized circle as the adult female matures, the anterior edge of the marsupial band of C. tabernicola is formed by a very sparse row of multilocular pores, whereas the anterior edge of the band in C. townsendi is formed by 3 or 4 dense rows of pores and the anterior edge of the band in C. morrilli is formed by 3 or 4 dense rows with 2 submedial patches bare of pores and setae. These species are scattered in the deserts of the southwestern United States and northern Mexico.
