Additional material examined
Immature ( MUSM – ENT 0508678 ) from Peru, Quispicanchi, Cusco, Michi Michani Cunca , Cordillera Carabaya (- 13.5792 S, - 70.5778 W), 3947 m a GoogleMaps .s GoogleMaps .l., 28 June 2006, Tracie Seimon col . GoogleMaps
Etymology
The specific epithet refers to the type locality where the species was found and also to the Cordillera Carabaya which is a mountain chain located in the southeast of Peru . It forms part of the Eastern Cordillera of the Andes and extends in a northwest–southeast direction for about 95 km, from the department of Puno . It also presents a glacier surface of 100 km 2 with its maximum elevation reaching 5780 m a .s .l.
Diagnosis
Females of H. carabaya sp. nov. can be easily distinguished from those of all other species of Hapalotremus by the spermathecae bearing an additional well-developed
apical median projection with a long thin wavy groove extending downward dorsal median from this projection ( Figure 18e, f View Figure 18 ). Male unknown.
Description
Holotype female (MUSM–ENT 0508676): Total length (not including chelicerae and spinnerets) 36.9. Carapace: length, 15.7; width 13.6. Abdomen: length 20.2. Fovea: procurved, width 2.1.
Colour pattern (live specimen): carapace dark, with pink setae on margins; legs dark with stripes on patellae distinct; abdomen black with red setae on urticating patch ( Figure 2a, b View Figure 2 ).
Eyes: anterior eye row procurved, posterior recurved ( Figure 18a View Figure 18 ). Eyes sizes and interdistances: AME 0.19, ALE 0.23, PME 0.28, PLE 0.24, AME–AME 0.30, AME–ALE 0.18, PME–PME 0.91, PME–PLE 0.11, ALE–PLE 0.24. Ocular tubercle: length, 1.60; width, 1.75. Clypeus: length, 0.25. Labium: length, 2.5; width, 3.0, with 16 cuspules ( Figures 17b View Figure 17 , 18b View Figure 18 ). Maxillae: right with 112 cuspules, left with 108 cuspules. Sternum: length, 6.4; width, 5.8. Three pairs of sternal circular sigillae, first pair hardly visible, second and third pairs visible, third pair about its length from the margin ( Figure 17b View Figure 17 ). Chelicerae: with 13 welldeveloped 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: 11.3, 6.8, 8.0, 6.8, 4.6, 37.5; II: 9.6, 5.8, 6.5, 6.1, 4.5, 32.5; III: 8.3, 5.3, 5.8, 7.8, 5.1, 32.3; IV: 10.7, 6.5, 8.2, 11.0, 5.5, 41.9; palp: 8.0, 5.2, 6.1, –, 5.8, 25.1. Field of spiniform setae on basal retrolateral coxal face of palp and legs I–IV. Spinnerets: PMS, 1.5 long; PLS, three-segmented, 5.3 long.
Scopulae: Ventrally, 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 one row of setae, II 1/2 scopulate divided by three rows of setae, III 1/4 scopulate divided by more than three 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: palp 0; I 2d; II 0; III 0; IV 0. Patellae: palp and legs I–IV 0. Tibiae: palp 1-2v; I 1v; II 1-2v, 1-1-1p, 1-1r; III 2-1-2v, 1-1-1p, 1-1r; IV 1-2-2v, 1p, 1-1-1r. Metatarsi: I 1-1v; II 1-2v, 1r; III 2d, 1-1-2v, 1-2-2-2-2p, 1-1-1r; IV 2d, 2-1-3v, 1-1-1-2p, 1-1-1- 1r. Tarsi: I–IV 0.
Genitalia: Spermathecal receptacle with basal portion much wider than apical; apical median region rounded and apical lateral projections slightly developed; presence of an additional well-developed apical median projection with a long thin wavy groove extending downward dorsal median from this projection ( Figure 18e, f View Figure 18 ).
Urticating setae: Type III present and arranged in one big dorsal median patch on the abdomen ( Figure 17c View Figure 17 ).
Distribution and habitat
Known only from type locality ( Figure 37 View Figure 37 ). Specimens were found on a hill under different rocks in close proximity to each other at about 4000 m a.s.l. ( Figure 3d, f View Figure 3 ). Spiders were located at 2:02 pm under misty weather conditions with drizzle. Day temperature on 30 June 2006 was 8°C but dropped to an overnight low of about −3.3°C.
