Types
Male holotype ( MUSM-ENT 0513026 ) from Peru, Cusco, Convención, Santa María , 1286 m a.s.l., 10.X.2018, R. Kaderka col.; male paratype ( MUSM-ENT 0513024 ) and female paratype ( MUSM-ENT 0513025 ), the same data as for the male holotype; female paratype ( MUSM-ENT 0513023 ) from Peru, Cusco, Convención, Santa María , 1213 m a.s.l., 10.X.2018, R. Kaderka col.
Etymology
The specific name is derived from the name of the type locality near Santa María , Cusco province, Peru .
Diagnosis
Urupelma sanctimariae sp. n. differs from U. ashaninka sp. n., U. johannae sp. n., U. atarraz sp. n. and U. megantonianum sp. n. in the absence of urticating setae of type IV (only type III are present).
The males of U. sanctimariae sp. n. differs from all congeners in the presence of short and stout embolus with well-developed PI, developed R and SA keel, PS keel is absent ( Figure 19 View Figure 19 ). Two unequal subapical apophyses are present on male tibia I, basally fused, both with short spine. Palpal tibia retrolaterally with a cluster of short spiniform setae, the retrolateral process is absent. Males of U. sanctimariae sp. n. differ from U. veronicae sp. n. and U. dianae sp. n. in having R keel developed and less developed TP in palpal bulb (weakly developed R keel and the presence of well-developed TP in palpal bulbs of U. veronicae sp. n. and U. dianae sp. n.).
Distribution
Known from the type locality in Peru, Cusco Department, La Convención province: Santa María ( Figures 23 View Figure 23 , 76 View Figure 76 , 77 View Figure 77 ) .

Variability
The variability in the shape of spermathecae is shown in Figure 24E–J View Figure 24 . In the male paratype (MUSM-ENT 0513024) the lengths of leg segments are shown in Table 9 View Table 9 . In this male paratype we have recorded a similar carapace length (13.00), 10–11 cheliceral teeth, labium with 60 cuspules, maxillae with 189–209 cuspules, and the congruent leg formula (IV> I> II> III).
Remarks
In juvenile specimen of female (MUSM-ENT 0513025), with carapace length 1.898, we sampled urticating setae of intermediate morphology between types III and IV, 0.13–0.16 long. These setae represent ontogenetic precursors of type III, which are present in mature specimens.
