Schizotetranychus baltazarae Rimando, Rimando (1962b)
Diagnosis
Female
- empodia I-IV = basal stalk (Fig. 8a) that is divided distally into two short, curved claws, thicker at base in lateral aspect; claws with a thin, curved dorsal hair, 3/4 length of claw (Figs 1, 2); minute proximoventral hairs present (Fig. 8a,b)
- pregenital striae fine, transverse, arching around genital flap; genital flap with mostly oblique striae (Fig. 3)
- tarsus I with the sockets of two tactile setae and one solenidion proximal to the socket of the proximal duplex seta
- tarsus II with the sockets of one tactile seta and one solenidion proximal to the socket of the duplex seta
- peritreme ending in short hook, like a golf club (Fig. 9)
- prodorsal striae longitudinal and distinctly broken, striae converging at a point just anterior to setae c1, forming a V-shape (Figs 4, 5)
- dorsal opisthosomal striae with strong lobes; longitudinal between c1-c1, d1-d1, e1-e1; transverse e1-h1 (Figs 6, 7)
- chaetotaxy for legs I-IV:
- femora 9, 6, 3, 3
- genua 5, 5, 3, 1
- tibiae 8(1+0), 5, 5, 5
- tarsi 15(3+3), 12(2+3), 8(1+0), 8(1+0)
Male
- empodia I-IV as in female (Fig. 8)
- peritreme same as female (Fig. 9)
- prodorsal striae fine, longitudinal, weak, widely spaced (Fig. 10)
- dorsal opisthosomal striae very fine, mixed patterns; with two weakly developed narrow transverse shields present, incorporating C-row and D-row (Figs 11, 12)
- coxae I enlarged, and leg I elongate (Fig. 13)
- femora I and II with enlarged thickened spur-like setae present (similar to that found on male Neonidulus) (Figs 14, 15)
- tarsus I with the sockets of three tactile setae and two solenidia proximal to socket of the proximal duplex seta
- tarsus II with the sockets of one tactile seta and one solenidion proximal to, and one tactile seta overlapping, the socket of the duplex seta
- chaetotaxy for legs I-IV:
- femora 9, 6, 3, 3
- genua 5, 5, 3, 1
- tibiae 11(4+0), 6(1+0), 5, 5
- tarsi 16(4+3), 12(2+3), 8(1+0), 8(1+0)
- aedeagus dorsally directed; no anterior or posterior projection (tip of projection curves posteriorly); dorsal margin of shaft at approx. 30° angle to ventral margin, abruptly bending dorsally at right angle forming dorsal projection; dorsal projection short, stout, finger-like, not tapering until very tip; dorsal projection curves posteriorly to form straight blunt tip; ventral margin of shaft straight (Figs 16-18)

Notes
Rimando (1962a) described and illustrated the aedeagus as much thinner and more strongly curved posteriorly to what is presented here of the holotype.
^^ ++ I consider Schizotetranychus baltazarae to be a suspected synonym of S. hindustanicus (Hirst, 1924). Until I examine and the holotype and paratypes of S. hindustanicus, the name S. baltazarae will be used here. However, this complicates the distribution records as specimens from northern Australia have been identified as S. hinustanicus.
