Abbreviations: length (L), width (W, in carapace it corresponds to posterior width), depth (D).
Pedipalps
(
Figs. 309–317
). Pedipalps very sparsely hirsute. Patella with 57–75 external and 22–26 ventral trichobothria. Chela with 4
V
series trichobothria located on the ventral surface. Femur and patella granulated. Femur with 5–6 granulose carinae, and patella with 5 carinae with dorsal and ventral patellar spurs pronounced. Manus dorsally with fine, rounded reticulated granules, which in the central area form an irregular dorsal secondary carina. External surface of chela densely covered by minute granules, with an almost regular external secondary carina. Movable fingers with ca. 50 IAD, which have the same size as MD (ca.
85 in
number) and create a second row; there are also 5 ID and 15 OD present.
Legs
(
Figs. 322–325
). Tibia and tarsomeres of legs with several setae not arranged into bristle combs on dorsal surfaces, but with rows of spinules on dorsolateral surfaces and on legs I
–
II also on ventrolateral surface. Tarsomere II of legs I–IV with row of 4–6 stout median ventral spinules, and two pairs of flanking setae. Femur with 3–4 and patella 4–5 carinae; both femur and patella granulated.

AFFINITIES. The most similar species is
S. grandjeani
in which the pedipalp chela has 4
V
trichobothria located on the ventral surface, and the pedipalp patella has 54–59 external and 22–23 ventral trichobothria. This unique combination was the key character for the genus
Dasyscorpiops
which is herein synonymized with the genus
Scorpiops
. These two species could be easily differentiated by the shape of the pedipalp segments which are in the female (male is unknown in both these species) more narrow in
S. grandjeani
than in
S. bastawadei
sp
.
n
.
(
Figs. 327–328
,
Table 2
, and fig.
12 in
Lourenço, 1998: 251
). In the females, pedipalp chela length to width ratio is
5.1–5.2 in
S. grandjeani
, vs.
3.8–4.4 in
S. bastawadei
sp
.
n
.
; pedipalp patella length to width ratio is
2.8–2.9 in
S. grandjeani
, vs.
2.4–2.6 in
S. bastawadei
sp
.
n
.
; and pedipalp femur length to width ratio is
3.6–3.7 in
S. grandjeani
