Figure 10. Electrophoresis plates of L. geometricus (1st and 3rd plates 
from left) and L. rhodesiensis (2nd and 4th plates). 1st and 2nd; 3rd and 
4th plates run together. Differences noted by arrows. 
Diagnosis The males are distinguished from L. geometricus by 
the additional coil of the embolus and by the lack of a spur on the 
conductor (Figs. 1-3). The epigynum is much like that of geometri- 
cus. The spermathecae are more heavily sclerotised than in geometri- 
cus and the coils of the ducts extend antero-laterally beyond the 
spermathecae (Fig. 4). The inner line of the pattern of the female 
abdomen seems more distinct (Figs. 7, 8). 
Records Rhodesia: I have collected specimens of L. rhodesiensis 
in Salisbury. Smooth cocoons have been found in Kariba (G. Begg), 
Darwendale (IRM) and Bulawayo (IRM). I have collected L. 
geometricus in Salisbury and Umtali. 
South Africa: J. Ledger (pers. comm.) collected a single female 
L. rhodesiensis in Walkerville (30 Km south of Johannesburg). G. 
Newlands has sent me specimens of L. geometricus from Pretoria 
(Transvaal), and Kroonstad and Boshof (Orange Free State). 
Mozambique: D. Broadley collected a single female L. geometri- 
cus with egg-sacs 35 Km south of Inchobe, on the new road to NE 
Mozambique. 
Botswana: There is a single female L. geometricus in the MCZ 
collection from Tonota (D. Carmichael).
