Neofedrizzia vitzthumi (Oudemans)

Toxopeusia vitzthumi Oudemans, 1927: 228 ; Oudemans, 1928: 66. Neofedrizzia vitzthumi -- Womersley, 1959: 48.

Type specimens. Holotype, F, INDONESIA: Buru: Wai Eno bis (“lot” on slide), Wai Temun (“Temoen” on slide), 3.ii. 1922, Buru (“Boeroe” on slide) (slide number 3564, registration P 1098). In Mus. Leiden.

Diagnosis. Female: idiosoma 745 long; anterior hyaline projection does not extend past CxI; exopodal patterning between CxII–III striped; pedofossae III and IV absent; seta h 1 with 10–11 barbs; distal spine-like process on palp femur present, ca. 10 long; one non-filamentous excrescence ribbon-like, the other a serrated blade; femur III and IV with large lamellae. Seta st 1 about as long as base of tritosternum; setae st 2 -st 3 ca. 15 long, seta st 4 broken or minute; sternogynial shield with anterior margin straight.

Redescription. Female: Idiosoma 740–745 long, 510 wide; anterior hyaline projection with 1 pair of barbed setae 20–28 long. Tritosternum base 43 long, 28 wide. Tetartosternum reticulate, sternal shield smooth; tetartosternum crown-shaped; st 1 barbed, 28–30 long, st 2 barbed, 15 long, st 3 8 long, st 4 minute. Sternogynial shield 115 long, 100 wide, smooth, 2 pores and 3 setae flanking each side of shield. Ventral shield smooth medially and in intercoxal region; pores and setae indistinct. Ventrianal shield 125 long, 350 wide, smooth, paranal setae 45–50 long, other setae minute; anterolateral corner of ventrianal shield not fused with ventral shield. Marginal shields probably smooth. Pedofossae III absent, CxIV-marginal suture present.

Legs. TrI obscured. FeI with seta pv 3 longer and thicker than setae pv 1 and pv 2. FeII with ventral lamella, seta pv 1 20 long, setiform, seta pv 2 30 long, setiform, seta ad 1 obscured, appears thickened. GeII with setae ad 3, pd 3 setiform. FeIII with small lamella distal to av 1; seta pv 1 barbed, not spine-like, only slightly thickened; seta pd 1 obscured. GeIII and TiIII with pd setae partially obscured, do not appear thickened. FeIV with lamella, expanded distal to av 1, seta pv 1 thick, spine-like, seta pd 2 just distal to ad 2; seta ad 2 thickened. TaII- IV with seta av 2 and av 3 spine-like, subequal in length to seta av 3.

Gnathosoma . Seta h 1 curved, with 8–9 barbs, 58 long, distance between h 1 –h 1 8; h 2 with several small barbs, 35–40 long; h 3 8 long, posterolaterad h 2; palpcoxal seta 12 long. Corniculi on small tubercles. Palp, seta av 1 on trochanter with few long barbs, 45 long; av 2 with few or no barbs, 45 long; palp femur with distal spine 13 long. Chelicera, fixed digit 145 long, movable digit 40 long; fixed digit with 2 large and 2 minute teeth; excrescences consist of a large brush-like process, a ribbon-like processes with a crenate and serrated margin and a serrated blade that is two-thirds length of the ribbon-like process.

Remarks. This species is known from the female only and is similar to N. leonilae .
