Additional material examined

One female and three immatures ( AMNH) from Bolivia, Chapare, Cochabamba, northeast of Sacaba (- 17.4036 S, - 62.0406 W), 3300 m a GoogleMaps .s GoogleMaps .l., 29 January 1976, L . E GoogleMaps . Peña col.


The specific name is a noun in apposition formed by the Quechua and Aymara word kuka , which means ‘coca’, referring to the plant species Erythroxylum coca Lam. 1786 originated from the Amazon Andes and used by Pre-Inca and Inca cultures for rituals in relation to men and nature ( Academia Mayor de Lengüa Quechua 2005).


Females of H. kuka sp. nov. resemble those of H. chasqui sp. nov. and H. martinorum by the large number of labial cuspules (more than 25 cuspules), but differ by the presence of scopulae on metatarsi IV ( Figure 27f View Figure 27 ) in combination with spermathecae having apical lateral projections well developed, elongated and located more apically than in H. chasqui sp. nov. and H. martinorum ( Figure 27g View Figure 27 ). Male unknown.


Holotype female (AMNH): Total length (not including chelicerae and spinnerets) 26.51. Carapace: length, 11.11; width 9.37. Abdomen length 13.73. Fovea: slightly procurved, width 1.7.

Colour pattern (in alcohol): carapace reddish brown with white short setae on margins and basal, legs brown with very long white setae on coxae, trochanter and femora, abdomen light brown with light yellow setae on urticating patch ( Figure 27a–c View Figure 27 ).

Eyes: anterior eye row procurved, posterior recurved ( Figure 27d View Figure 27 ). Eyes sizes and interdistances: AME 0.12, ALE 0.19, PME 0.10, PLE 0.14, AME–AME 0.18, AME–ALE 0.12, PME–PME 0.43, PME–PLE 0.05, ALE–PLE 0.11. Ocular tubercle: length, 0.92; width, 0.64. Clypeus: length, 0.2. Labium: length, 1.34; width, 1.79, with 27 cuspules ( Figure 27e View Figure 27 ). Maxillae: right with 115 cuspules, left with 112 cuspules. Sternum: length, 5.15; width, 4.76. Three pairs of sternal oval sigillae, all pairs hardly visible ( Figure 27b View Figure 27 ). Chelicerae: with 9 well-developed teeth on promargin of furrow and 19 small teeth on the retromargin.

Leg formula: IV> I> II> III. Length of legs and palpal segments (femur, patella, tibia, metatarsus, tarsus, total): I: 7.09, 5.15, 5.1, 3.94, 3.31, 24.59; II: 6.79, 4.64, 4.42, 4.69, 3.79, 24.3; III: 5.12, 3.9, 4.24, 5.04, 3.7, 22.0; IV: 8.3, 5.35, 6.01, 7.68, 3.98, 31.3; palp: 5.56, 3.7, 4.12, -, 3.84, 17.2. Field of spiniform setae on basal retrolateral coxal face of palp and legs I–IV. Spinnerets: PMS, 0.8 long; PLS, three-segmented, 4.2 long.

Scopulae: All tarsi densely scopulate and divided by conical long setae increasing in number from tarsus I to IV. Metatarsi I 1/2 scopulate divided by three rows of setae, II 1/3 scopulate divided by three rows of setae, III 2/3 scopulate divided by approximately six rows of setae, IV 1/4 apical scopulate divided by approximately eight rows of setae. Dorsal face of all tarsi with two parallel rows of non-plumose clavate trichobothria interspersed with filiform, separated by a row of long, thin setae.

Chaetotaxy (left side): Femora: Palp 1d; III 1d; legs I, II and IV, 0. Patellae of palp and Legs I–IV, 0. Tibiae: palp 1-2v, 1-1r; I 1-2v; II 1-2v, 1p, III 2-1-2v, 1-1-1p, 1r; IV 1-1-2v, 1-1r. Metatarsi: I 1-3v; II 2-3v; III 1-2-3v, 2-1p, 1-2-1-1r; IV 2-2-1-2v, 1-1-1r, 1-1- 1p. Tarsi: I–IV 0.

Genitalia: Single spermathecal receptacle with basal portion wider than apical and basal projections well-developed, in combination with apical lateral projections welldeveloped, elongated and located apically ( Figure 27g View Figure 27 ).

Urticating setae: Type III present and arranged in one dorsal posterior patch on the abdomen ( Figure 27c View Figure 27 ).
