( Figures 59–61 , 78F ; Table 20 ) Types Female holotype ( MUSM-ENT 0514015 , exuvia RKCP 0685 ) from Peru , Cuzco province , Quincemil , 746 m a .s .l ., 18 October 2014 , R . Kaderka col. Etymology The specific name is a patronym in honour of Jana Kaderkova, wife of the first author, for her patience and support, and also her indulgence of his unusual hobby. Diagnosis The females of U. johannae sp. n. differ from all congeners, except for U. ashaninka sp. n. , in having oval seminal receptacles basally joined ( Figure 61 ). It differs from U. ashaninka sp. n. in a different colouration, the absence of type III urticating setae and the extension of urticating setae patch in females (more extended in U. johannae sp. n. and less extended in U. ashaninka sp. n. ) ( Figures 37C and 60D ). Distribution and natural history Known from the type locality in Quincemil , Cuzco , Peru ( Figure 76 ) .

Labium length 1.77, width 2.48, anterior third with 54 cuspules, maxillae with 170–191 cuspules in basal half, short spiniform setae in apical half absent. Sternum length 5.80, width 5.28, with three visible pairs of sternal sigilla located near coxae III (length 0.49, 0.64 from edge of sternum), coxae II (length 0.29, 0.47 from edge of sternum) and coxae I (length 0.23, 0.46 from edge of sternum).

Tarsal scopulae I undivided, tarsal scopulae II divided by a longitudinal band of setae, in tarsi III, IV divided by a wide band of setae. Dorsal face of all tarsi and cymbium with two irregular longitudinal rows of very short claviform trichobothria. Denticulation of paired tarsal claws on left legs (prolateral/ retrolateral row): I 0/3, II 4/4, III 3/2, IV 3/3. Plumose setae on retrolateral face of femur IV absent. Figure 59.
