Neoscirula queirozi sp. nov.

(figs. 18–26)

Type-specimens. Holotype male on slide, litter under Attalea dubia Burret, Estação Experimental IAC, Pariquera-Açu, São Paulo, 18 April 2000, A. R. Oliveira.

Diagnosis. Adults of this species can be identified by the very long tapering cylindrical solenidia (tcsl) on tarsi I and II, nearly reaching the pulvillus. Tarsi I with a semi-globose proximal solenidion. Natural colour and specific feeding habits unknown.

Description. Male. (figs. 18–26) Dimensions. Idiosoma: length 140; width 110; length hypognathum 45; width hypognathum 45; length palp 34–35; length chelicera 72; length leg I 115 (112–117); leg II 118 (111– 126); leg III 114 (112–115); leg IV 130; length sensillae vi 77, sce 68.

Dorsum (fig. 18). Single idiosomal shield finely papillated and poorly demarcated (fig. 18). Idiosomal striae papillated. Lyrifissures and setae f 1 on posterior edge of the idiosomal shield. Setae ve and h 1 the longest dorsal setae. Sensillae finely pilose; vi longer than sce. Setae f 2 absent. One pair of para-anal and 2 pairs of anal setae present.

Ve n te r (fig. 19). A weakly sclerotised shield covers nearly the entire venter and includes all the coxae (fig. 19). Its anterior border is just in front of coxae I; its posterior border is just in front of the genital valves. It carries all coxal (see below), propodogastral, paracoxal setae; and the 6 hysterogastral setae; provided with very papillated striae. Faint subcuticular sculpturings (apodemes) mainly found between coxae I and II. The striae surrounding the genital and anal regions papillated. Lyrifissures ventrolaterad to anal valves. Genital valves with 4 pairs of g –setae; paragenital setae absent.

Gnathosoma (figs. 20– 22). The integument of all gnathosomal structures papillated.

Palp (fig. 20). Palp femora not divided except for extremely faint sutures (fig. 20).. The palpal chaetotaxy as follows: trochanter, no setae; basifemur, 1 dorsal spine-like seta; telofemur, 1 spine-like seta; genu 3 sts; tibiotarsus, 4 sts, 1 bend tubercle, 1 tsl and a claw.

Chelicerae (fig. 21). Broad proximally and tapering gradually towards the chela. Cheliceral setae conspicuous ( Fig. 21 ).

Hypognathum (fig. 22). As long as wide terminating anteriorly into broad entomalae (fig. 22). Adoral setae not detected. The slightly bend hg 1 setae longest of four pairs of hg setae.

Legs (figs. 23– 26). All legs shorter than the body. Tarsi ending bluntly distally. All leg segments papillated. Leg chaetotaxy: coxae I–IV, 3 sts, 1 peg-2 sts (plus 1 pgsts)-3 sts-2 sts (plus 1 pcsts); trochanters I–IV, 1-1-2-1 sts; basifemora I–IV, 4-4-3-1 sts; telofemora I–IV, 5-5-4-3 sts; genua I-IV, 3 asl, 1tcsl, 4 or 5sts-3 asl, 4 sts- 1 asl, 5 sts-2 asl, 5 sts; tibiae I–IV, 1 tcsl, 5 sts-1 bsl, 5 sts-1 asl, 5 sts-1T, 4 sts; tarsi I–IV, 2 bbsl, 2 asl, 2 tsl, 1 peo,16 sts-1 tcsl, 1 tsl, 15 sts-1 tsl, 12 sts-12 sts.

Etymology: This species named in honour of Luiz Vicente de Souza Queiroz, founder and first financer of the Escola Superior de Agricultura “Luiz de Queiroz” (ESALQ), in Piracicaba, State of São Paulo, Brasil.
