Genus NEOSCIRULA Den Heyer, 1977

Neoscirula Den Heyer, 1977: 74

Type species: N. theroni Den Heyer, 1977: 75

Diagnosis

Dorsum with a weakly-sclerotized propodosomal plate not clearly demarcated by edges, the surface with papillae or granulation, sometimes subcuticular reticulations. Hysterosomal plate sometimes present in males. Integument lateral to the propodosomal plate and dorsal hysterosoma with papillae-bearing striations. One pair of dorsal cupules (im) near to f1, f2; one pair of ventral cupules (ip) near h1, anal valves, and one pair of cupules (ih) at genital valves. Coxal plates I–II may be separate as laterocoxal plates or fused; coxal plates III– IV, are confined to the coxal bases. Medial region of coxae I–II with or without subcuticular cells. Two pairs of anal setae and one pair of paranal setae. Hypognathum is cone-shaped distally and papillate. Four pairs of hypognathal setae, hg1-4, hg1 is longest and stoutly bent or sometimes thickly elongated. Entomalae with two pairs of small adoral setae. Palps five segmented, ending in claw, and projecting slightly beyond the apex of the hypostome. Trochanter lacks setae; basifemora and telofemora fused but with distinctive suture, dorsally with a simple or spine-like setae on each of these segments. Genua has four simple setae of which the dorsal one is very long, one apophysis may be present. Tibiotarsi have six setae, 2 long dorsal setae, 1 proximiventral and lateral, 2 subterminal ventral, on inner margin simple seta or tubercle-like seta is present. All segments with papillae. Claw with or without a tooth on its mesal margin. Chelicera three segmented and thin at distal part and broad proximally, dorsal cheliceral seta close to chela.

Diagnosis. Adults can be distinguished from other members of the genus by the rounded propodosomal plate with verrucate integument, and also by leg chaetotaxy as follows: genua I with 4 ats and 4 sts; tibiae I with 2 bsl and 4 sts; tarsi I with 4 solenidia (2 ats, 2 bsl), 1 depression and 20 sts; tarsi IV with 20 sts.

Palp ( Figs. 2 View FIGURE 2 A–B) with 5 segments, length of palp 61, with papillae ornamentation. Chaetotaxy of segments as follows: Trochanter none; basifemora with 1 dorsolateral spinelike seta; telofemora with 1 dorsolateral bent long and stout spinelike seta; genua with 2 dorsal simple setae and 2 ventral simple setae; tibiotarsi with 2 long and 1 short simple tactile seta ventrally, 1 long and 1 short setae dorsally, 1 tiny tubercle apically on inner margin. Tibiotarsal claw with 2 teeth on mesal margin, of bifid appearance. Chelicera ( Fig. 2 View FIGURE 2 C) 76 long, thin at distal and broad at proximal part; dorsal integument smooth and venter densely covered with fine papillae; cheliceral seta very short, at dorsal region of chela.

Discussion. This species resembles Neoscirula sevidi ( Den Heyer, 1977) by having several characters in common: a funnel–shaped hypostome that is short and thick and the coxal region subrectangular in shape; the hypostomal setae hg1 stout and bent; palpal basifemora with spine-like setae; dorsal cheliceral setae very short; dorsal hysterosoma with setae h2 present; ventrally with 7 pairs of simple setae between coxae III–IV; and coxal plates I–II widely separated, not fused medially, without subcuticular cells and with papillae-bearing, striated integument. N. aliciae sp. nov. can be separated from N. sevidi by: propodosomal plate with verrucate integument (the propodosomal plate bears randomly distributed papillae in N. sevidi ), palpal tibiotarsal claw with a tooth on mesal margin claw (simple claw in N. sevidi ), the distal hypostomal region covered dorsolaterally with a membrane ( Fig. 2 View FIGURE 2 A) (without membrane in N. sevidi ), palpal telofemora with 1 thick spinelike and bent setae (normal in N. sevidi ), and chaetotaxy of genua IV and tarsi II (2 ats, 5 sts; 1 ats, 20 sts, respectively), but in N. sevidi there are 1 ats, 5 sts in genua IV and 1 bsl, 1dt, 1 tsl, 21sts in tarsi II.
