A Survey of the Scorpion, Fauna of South Africa.

Museum collection with the types of chlorodermus, Mr. S. Hirst informs me 
that the two species are without doubt identical ; Prof. Kraepelin holds the 
same view (10). 
Distribution : An East African species recorded from Tette and Lake 
Nyassa. Kraepelin has no records of this species from G-erman East Africa. 
We have it from Salisbury (R. Graham and C. von Hirschberg) ; the 
Ehodesian Museum has it from Hillside Bulawayo, from the Matoppos and 
from Eedbank. 
Key to the South African Species of the Genus JJroplectes. 
A. Abdominal tergites with a short or very short lateral keel on each side 
posteriorly, in addition to the median keel ; the granular roios on the 
movable finger of the pedijoalp are fianked internally by isolated 
granules which are opposite to the apices of the rctvs ; each row hasally 
on its outer side has two strong granules. (1 — 4.) 
(a) Vesicle of tail ivithout a distinct tooth beneath the aculeus : pectinal 
teeth I'd-^l. (1-3.) 
(1) Inferior median keels of first four caudal segments in the 
male quite absent ; last sternite not keeled ; hand about as 
wide as the brachium ; fourth caudal segment very slightly 
more than 2| times as long as broad ; pectinal teeth 29-30 ; 
tail and palp strongly pilose. (A specimen believed to be 
the female is described as having 31 pectinal teeth, the basal 
one shorter than the rest ; the tail shorter than that of the 
male) U. pilosus, Thor. 
2. Inferior median caudal keels distinct, those of segments I and 
II sometimes smooth ; last sternite with 2 or 4 keels ; pec- 
tinal teeth 21-27, the basal tooth in the female either un- 
modified or much broader than the other teeth ; hand with 
rounded upper surface, only a little wider than the brachium. 
U. carinatus, Poc. 
3. Eesembling carinatus, but the hand much broader and flatter, 
the inner edge being rather sharp : basal pectinal tooth of 
adult female considerably elongated and sickle-shaped. 
U. planimanus, Karsch. 
(b) Vesicle granular with a distinct triangular tooth beneath the 
aculeus ; pectines of ftmnle with 15 teeth, the basal one greatly ex- 
panded, but not elongate. (4.) 
4. First three caudal segments with 10 keels each ; hand about 
as wide as the brachium ; tergites adorned with 7 longi- 
tudinal black lines U. variegatus, Koch. 
B. Ahdoniind tergites loithout lateral crests; tail almost without crests, 
the superior keels being rf-presented by a terminal granule and some- 
times also in segments I, T I, and III by a roio of smaller granules ; 
inner set of granules on the movable finger isolated, but these granules 
lie far from the apices of the adjacent median rows, except near the
