description: Hapalotremus marcapata sp. nov.   
(Figures 1f, 28, 29, 37)  
 Type material   
Female holotype (MUBI) from Peru, Quispicanchis, Cusco, Marcapata, Huancarayoc (Marcapata Valley) (- 13.6028 S, - 70.9542 W), 3368 m a.s.l., 20 February 2006, Juan C. Chaparro col.  
 Etymology   
The specific epithet ‘Marcapata’ corresponds to the Quechuan word, which means on the summit; and also to Marcapata Valley, located in the Andes in southern Peru, Cusco Department, which belongs to the Vilcanota mountain chain.  
 Diagnosis   
 Females of H. marcapata sp. nov. differ from those of all other species of Hapalotremus by the colour pattern, being entirely black with red setae on dorsal abdomen urticating patch (Figure 1f). Additionally, females of H. marcapata sp. nov. can be distinguished from those of all other species by the femora of palp and legs I–IV bearing a single dorsal spine, in combination with the shape of the spermathecae having its basal portion much wider than apical; noticeably domed apical median region and apical lateral projections slightly developed (Figure 29e). Male unknown.   
 Description   
Holotype female (MUBI): Total length (not including chelicerae and spinnerets) 40.0. Carapace: length, 17.3; width 15.2. Abdomen in bad condition: length 22.0. Fovea: slightly procurved, width 2.3.  
Colour pattern (live specimen): entirely black with pink hairs on margin of carapace and with red setae on dorsal abdomen urticating patch (Figure 1f).  
Eyes: anterior eye row procurved, posterior recurved (Figures 28a, 29b). Eyes sizes and interdistances: AME 0.26, ALE 0.28, PME 0.30, PLE 0.19, AME–AME 0.38, AME–ALE 0.29, PME–PME 0.87, PME–PLE 0.16, ALE–PLE 0.24, Ocular tubercle: length, 1.4; width, 1.9. Clypeus: length, 0.3. Labium: length, 2.0; width, 2.6, with 18 cuspules (Figure 29a). Maxillae: right with 126 cuspules, left with 112 cuspules. Sternum: length, 7.6; width, 7.2. Three pairs of sternal elongated sigillae, all pairs hardly visible (Figure 28b). Chelicerae: with 13 well-developed teeth on promargin of furrow and 18 small teeth on the retromargin.  
Leg formula: IV> I> II> III. Length of legs and palpal segments (femur, patella, tibia, metatarsus, tarsus, total): I: 11.9, 7.5, 8.4, 7.3, 5.0, 40.1; II: 11.6, 6.2, 5.8, 8.3, 5.1, 37; III: 10.1, 5.6, 6.5, 8.8, 5.4, 36.4; IV: 12.7, 6.5, 10.1, 13.5, 7.0, 49.8; palp: 7.7, 4.9, 6.0, –, 6.2, 24.8. Field of spiniform setae on basal retrolateral face of palp and legs I–IV. Spinnerets: PMS, 1.1 long; PLS, three-segmented, 5.8 long.  
Scopulae: All tarsi densely scopulate and divided by conical long setae increasing in number from tarsus I to IV (Figure 29c, d). Metatarsi I 2/3 scopulate divided by three rows of setae, II 1/2 scopulate divided by three rows of setae, III 1/4 scopulate divided by approximately six rows of setae, IV with no scopulae. 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 of palp and Legs I–IV, 1d. Patellae of palp and Legs I–IV, 0. Tibiae: palp 2v, 1p; I 1p; II 1-1v, 1-1p, III 1-1-2v, 1-2-1p, 1-1r; IV 1-1-2v, 1-1-2-1p, 1-2-2- 1r. Metatarsi: I 1-2v; II 1-2v, 1p; III 2-2-1v, 1-1-2-2p, 2-2-2r; IV 1-1-2v, 2-2-1-2-2r, 2-1-1-1-2- 2p. Tarsi: I–IV 0.  
Genitalia: Single spermathecal receptacle with basal portion much wider than apical; noticeably domed apical median region and apical lateral projections slightly developed (Figure 29e).  
Urticating setae: Type III present, abdomen in bad condition (Figure 28c).  
 Distribution and habitat   
Known only from the type locality, at about 3300 m a.s.l. (Figure 37).
