Hapalotremus kuka sp. nov.

( Figures 27 , 36 )

Type material

Female holotype ( AMNH) from Bolivia, Chapare, Cochabamba, northeast of Sacaba (- 17.4036 S, - 62.0406 W), 3300 m a .s .l., 29 January 1976, L . E . Peña col.

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 .s .l., 29 January 1976, L . E . Peña col.

Etymology

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).

Diagnosis

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 ) 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 ). Male unknown.

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.
