Coleobonzia moraesi sp. nov.

(figs. 10–18)

Type specimen. Holotype female on slide. From soil; Cerrado Campus-USP, Pirassununga-SP, Brazil, 03/ V/ 2000.A.R. Oliveira.

Diagnosis. This species can be distinguished from its Brazilian counterpart in this paper by the number of the genital setae, 4 pairs plus one pair of paragenital setae. Also by the markings on the propodosomal shield and the difference in chaetotaxy of basifemora II –IV, being 4-4-2 sts.

Description. Female. Dimensions. Idiosoma; length, 335; width, ± 180 (body somewhat distended by mounting); length hypognathum, 101; width of hypognathum, 73; length palps, 93–94; length chelicerae, 97; length legs: I, 157–164; II, 155–160; III, 180–183; IV, 195–197; vi & sce, 80–83.

Dorsum (fig. 10). Sensillae pilose and of equal length. Propodosomal shield demarcated from surrounding integument by not being striated and being randomly papillated; it is ornamented with lateral patterns (fig. 10; partially reconstructed). Dorsal hysterosomal striae very finely papillated (stippled area due to stretching of integument where striae are vague). Hysterosomal dorsal setae all short; f 2 present. Lyrifissures prominent. Two pairs of anal setae.

V enter (fig. 11).Ventral striae very finely papillated. Area posteriad to the gnathosoma not striated but provided with fine papillae.The four coxal regions are faintly demarcated. Genital valves papillated; without striae. Genital setae 4 pairs (fig. 11). Eleven hysterogastral setae. One pair of para-anal setae present.

Gnathosoma (figs. 12–14).

Palp (fig. 12). Chaetotaxy of palp is: trochanter 0; basifemora,1 dorsal sts; telofemora, 1 dorsal sts; genua, 4 sts; tibiotarsi, 1 small peg-like ventral seta, 1 tsl, 4 sts, 1 claw (fig 12). Most segments provided with dorsal papillae. Palps extend with approximately half the length of the tibiotarsus past the entomalae.

Chelicerae (fig. 13) Cheliceral setae present. Cheliceral segment I as well as the proximal part of segment II papillated.

Hypognathum. Setae hg 2-4 longer than hg 1; 2 pairs of short adoral setae. Coxal region with broken striae. Hypostome with prominent entomalae. Length: width ratio is 1.38. Coxal region of the hypognathum is provided with finely broken striae while the base of the hypostome is nearly randomly stippled (fig. 14).

Legs (figs. 15–18). Leg chaetotaxy is as follows: coxae I–IV, 3 sts, 1 peg-2 sts, 1 propodogastral sts-3 sts- 2 sts, 1 paracoxal sts; trochanters I–IV, 1-1-1-1 sts; basifemora I–IV, 4-4-4-2 sts; telofemora I–IV, 5-5-4-3 sts; genua I–IV, 3 sol, 5 sts--1 sol, 5 sts-1 sol, 5 sts-1 sol, 5 sts; tibiae I–IV, 1 sol, 5 sts-1 sol, 5 sts-1 sol, 5 sts-1 T (approximately as long as tibia), 4 sts; tarsi I–IV, 1 peo, 3 sol, 2 tsol, 16 sts-1 sol, 1 tsl, 18 sts-1 tsl, 17sts-16 sts.

Male and developmental stages. Unknown.

Etymology. This species is named for Prof. Dr. Gilberto José de Moraes.
