Etymology

A compound word whose first element is the Latin adjective albus meaning white, and the second element is the genitive Latin noun pes meaning foot, that refers to the distinctive white-legged coloration ( Simon 1903).

Amended diagnosis

The following character combination, modified from Schmidt (1993), is diagnostic for H. albipes   . Carapace and legs entirely covered dorsally with white setae, except femora of legs and palps, which are dark grey ( Figures 1a View Figure 1 , 7a View Figure 7 , 9a View Figure 9 ), abdomen dark with rounded dorsal median patch of reddish-orange urticating setae, and two or three white spots dorsally (more noticeably on females), the bigger spot is arrow-shaped, and with three or four white lines posterior laterally in each side of abdomen, reaching the urticating patch ( Figures 1a View Figure 1 , 9c, d View Figure 9 ). Labium wider than long bearing a reduced number of cuspules (6–13) ( Figures 7e View Figure 7 , 9b, f View Figure 9 ). Absence of spiniform setae on pro- and retrolateral coxal faces of legs I–IV. Metatarsi IV with no scopulae ( Figure 9h View Figure 9 ). Male tibia I very short, more than 20% shorter than metatarsus I ( Figure 7g View Figure 7 ). Male palpal tibia with retrolateral rounded process developed ( Figure 7h, i View Figure 7 ). Palpal bulb base with a basal digitiform apophysis well-developed ( Figure 8a–d View Figure 8 ); embolus thick and very curved to the retrolateral face and prolateral keels slightly developed; PI bearing a ventral medial crest pointed at distal end and located half way forward of embolus ( Figure 8a, b View Figure 8 ). Female spermathecae consist of one receptacle with basal portion slightly wider than apical, apical lateral projections slightly developed and apical median region depressed ( Figure 9j View Figure 9 ). Urticating setae: type III present on male and female and arranged in a dorsal median patch on the abdomen ( Figures 7c View Figure 7 , 9c View Figure 9 ).

Variation (from additional material examined)

Total length, females (n = 3): 26.7–29.8 (mean = 28.3 ± 1.5SD); carapace length, females: 12.4–13.8 (13.1 ± 0.7); length of palp and legs, females: palp 17.8–20.4 (18.9 ± 1.3), I 25.4– 31.5 (27.9 ± 3.1), II 24.2–28.3 (26 ± 2.07), III 23.6–25.5 (24.8 ± 1.04), IV 31.4–33.4 (32 ± 1.15). Labial cuspules, females 10–13, maxillary cuspules, right 91–120, left 96–118.

Distribution and habitat

The holotype male described by Simon (1903) gives no indication other than ‘Chaco’ for the type locality and this involves a large region in Bolivia. In the same way, Schmidt (1993) described the female of H. albipes   for the first time but did not provide a locality for those specimens, only ‘Bolivia’. A specimen of H. albipes   is shown in Figure 1a View Figure 1 and was located in La Paz ( Bolivia) at about 4252 m a.s.l., near the type locality. Here, we provide records of this species for Unduavi, Coscapa and Botijlaca (among 3200 and 3600 m a.s.l.), Bolivia ( Figure 36 View Figure 36 ). These sites are located east of Cordillera Real on the edge of the Yungas region, which constitutes a transition between the highlands of the Andes and the tropical lowlands of the Amazon rainforests. The annual average temperature of this area is 17.4°C with monthly average values ranging from 15°C in June and 19°C in December. The average annual precipitation is 725 mm, with a dry season from May to August and a wet season from December to February (www.censosbolivia.ine.gob.bo).
