A taxonomic revision of the genus Phyxioschema (Araneae, Dipluridae), II: species from Central Asia

摘要

Phyxioschema raddei Simon, 1889 is revised. A re-examination of type specimens confirms the synonymy of P. raddei and Ischnothele strandi Spassky, 1937, but the synonymy of Afghanothele lindbergi Roewer, 1960 and A. striatipes Roewer, 1960 cannot be confirmed due to the immature state of their types. The copulatory organs of the female holotype and other females from different localities are illustrated for the first time. Variation in morphological characters is shown. New records are given for Iran, Turkmenistan, Uzbekistan, Kazakhstan and Tajikistan. Phyxioschema females from Pakistan cannot be attributed to any nominal species and are left unnamed. A new species, P. roxana, is described from male and female specimens collected at eight localities in southern Uzbekistan and western Tajikistan. Relationships between Central Asian and Southeast Asian species are discussed. A summary of relevant morphological characters of all Phyxioschema species is given.
