Figs 27 View FIGURES 27 ¯57; Map 1

Eutichurus marquesae Bonaldo, 1994: 130 , figs 80, 81. Female holotype from Colombia, Cundinamarca, Santa Fé de Bogotá, La Uvita, I.N. Maria leg. (MNRJ 152, not re-examined).

Diagnosis. Males of E. marquesae resemble those of E. paredesi n. sp. and E. madre by the MA with a long, retrolaterally directed median prong ( Figs 1 View FIGURES 1 , 23 View FIGURES 23 ) but can be distinguished from both species by the presence of a long embolar prolateral process inserted medially ( Figs 27 View FIGURES 27 , 28). Females resemble those of E. madre (see Bonaldo 1994: fig. 79) but differ by the smaller semi-circular sclerotized area on the anterior projections, which are not projected over the posterior plates ( Fig. 52 View FIGURES 52 ; Bonaldo 1994: fig. 80).

Description. Male (ICN-Ar 6474). Colour in ethanol: carapace brownish red, cephalic region darker, thoracic groove mark brown. Chelicerae dark red. Endites and labium brownish red. Sternum orange with brown margins. Legs orange. Chelicerae with 4 promarginal teeth, the third the largest, the first a denticle, and 4 retromarginal teeth, the first close to the second, others separated by their width. Abdomen pale yellow, with dense hairs. Tarsi I– IV with dense scopulae, metatarsi III–IV with sparse scopulae. Total length 14.0. Carapace 6.8 long, 5.3 wide. Eye diameters: AME 0.33, ALE 0.31, PME 0.23, PLE 0.27. Eye interdistances: AME–AME 0.40, AME–ALE 0.56, PME–PME 0.45, PME–PLE 0.70, AME–PME 0.35, ALE–PLE 0.17, clypeus AME 0.18, clypeus ALE 0 23. Leg and palp measurements: palp 6.3 (2.8, 1.1, 1.7, -, 2.3); leg I 24.2 (6.4, 2.8, 6.0, 6.4, 2.6); leg II 22.7 (5.9, 2.8, 5.5, 6.0, 2.5); leg III 18.3 (5.2, 2.5, 4.1, 4.6, 1.9); leg IV 22.9 (6.0, 2.6, 5.4, 6.5, 2.4). Leg formula I-IV-II-III. Spination: palpal femur: d 0-1-1; tibia p 1-1. Leg. I femur d 1-1-0, p 0-0-1, r 0; tibia d 0, p 0, r 0, v 2-2 -p1; metatarsus d 0, p 0, r 0, v 2 -p1-1.

IIIfemur d 1-1-0, p 0-d1-d1, r 0-d1-d2; tibia d 0, p 1-1, r 1-1, v 2-2 -2; metatarsus d p1r1-p1r1-p1r1, p 0-0-1, r 0-0-1, v 2-2 -1.

Spinnerets: ALS nearly conical, contiguous, with two major ampullate and numerous smaller piriform gland spigots; PMS with two minor ampullate and about 15 aciniform gland spigots; PLS with distal article very long and narrow, with at least 19 aciniform gland spigots ( Figs 42 View FIGURES 42 ¯47); book lung cover pilose, without sculpture ( Fig. 48 View FIGURES 48 ); abdominal vestiture of setae composed of longer plumose hairs and thin cylindrical scales with very short superficial barbs (Fig. 49); epiandrum without spigots (Fig. 50). Palp: tibia thin, almost the same length of cymbium; RTA strong, single, with large ventral, apical process. Tegular process small; MA apically placed, median prong large; conductor hyaline; embolus inserted sub-basally, with a slender, long prolateral process inserted medially ( Figs 27 View FIGURES 27 ̄29).

Female. Described by Bonaldo (1994: 130). Complementary description: Tarsus I ( Fig. 30 View FIGURES 30 ) with two claws with at least ten teeth, on midline of claw, claw tufts inserted on articulate plates, numerous tenent setae with moderately expanded tips (Figs 32, 33), and at least 12 trichobothria in two rows. Tarsus IV similar to I (Fig. 31); scopular setae (Fig. 33) long and slender, with simple socket and tenent surface oriented distally; bothrium (Fig. 34) with several transversal ridges on proximal hood, trichobothria shaft with basal expansion covered by small bumps; tarsal organ (Fig. 35) capsulate, with oval opening. Spinnerets ( Figs 36 View FIGURES 36 ¯41): ALS as in male, PMS with two minor ampullate, about 30 aciniform, and about 4 cylindrical gland spigots with slightly thicker shafts than the aciniforms. Book lung atrium with well-formed mesh (Fig. 51). Epigynum ( Figs 52 View FIGURES 52 ̄57) with bulbous posterior plates closing over median field ( Figs 52 View FIGURES 52 , 53), primary spermathecae small, fertilization duct not advanced (Figs 54, 55), secondary spermatheca with long stalk and many gland pores (Figs 55, 56), internal side of epigynum lined with cuticular gland ducts (Fig. 57).
