Types
Male holotype ( MUSM-ENT 0513021 ) from Peru, Cusco, Convención, Santa Teresa , 1876 m a .s .l., 9 .X .2018, R. Kaderka col .; female paratype ( MUSM-ENT 0513022 ) from Peru, Cusco, Convención, Santa Teresa , 1932 m a .s .l., 9 .X .2018, R. Kaderka col.
Etymology
The specific name is derived from the name of the type locality near Santa Teresa , Cusco province, Peru .
Diagnosis
Urupelma sanctitheresae 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. sanctitheresae sp. n. differ from all congeners in the presence of short and stout embolus with well-developed PI and developed R keel, PS keel is bipartite with separate tegular and embolar part ( Figure 13E–H View Figure 13 ). Two unequal subapical apophyses are present on male tibia I, basally fused, both with short spine. Palpal tibia retrolaterally without a cluster of short spiniform setae, the retrolateral process is absent. Males of U. sanctitheresae 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.). Tegulum of palpal bulb in U. sanctitheresae sp. n. is not as pronounced in comparison with that of U. peruvianum comb. n.
Distribution
