Desoria sp. B

One specimen collected together with olympica at the type locality differs from that species by its larger size (1.2 mm) and a denser uniform cover of setae with macrochaetae hardly differentiated from ordinary setae. Median abd. 5 macrochaeta is only 1.8 times as long as inner edge of last claw, sensilla of the abdominal tergites are inserted in the p-row, but number is unclear (not as reduced as in olympica ). None of the other species of the cryophila group have so short uniform setal cover as this probably undescribed species.
