Figures 6–9: Pandinus mazuchi sp. n., ♀ holotype photographed at the type locality (6–7) and the type locality, Ethiopia, Jijiga env., 09°20'15.8"N 42°42'17.5"E, 2100 m a.s.l. (8–9).

Figures 10–13: Pandinus phillipsii (Pocock, 1896). 10–11. ♂ (125 mm), dorsal and ventral views, Somaliland, 15 km N of Sheikh, Goolis Mts., 09°58.927'N 45°10.377'E, 1247 m a.s.l. 12–13. ♀ (109 mm), dorsal and ventral views, Somaliland, Sheikh, 09°57'25.9"N 45°09'52.2"E, 1492 m a.s.l.

Figures 14–16: Pandinus phillipsii (Pocock, 1896). Juvenile (80 mm) at the locality Somaliland, Sheikh, Goolis Mts., 09°56'23"N 45°11'14.2"E, 1439 m a.s.l. The large photo (14) is an overall view after overturning a smaller boulder. The smallest photo (15) shows a shallow depression under the boulder in which the scorpion was hiding and underwent an ecdysis (the same spot is shown in the large photo by an arrow). Small arrow points to a partial exuvia of this specimen. The lower photo (16) shows the entire juvenile after removal from the hiding place.

Figures 17–19: Pandinus phillipsii (Pocock, 1896). 17–18. ♀ (109 mm) at the locality Somaliland, Sheikh, 09°57'25.9"N 45°09'52.2"E, 1492 m a.s.l. 19. ♂ (125 mm) on a tree after removal of dry bark, Somaliland, 15 km N of Sheikh, Goolis Mts., 09°58.927'N 45°10.377'E, 1247 m a.s.l.

Figures 20–22: Pandinus smithi (Pocock, 1897), ♂ (107 mm), at the locality, Ethiopia, 55 km S of Degehbur, 07°49'27.2"N 43°41'56.3"E, 1053 m a.s.l. Red arrow points to the spot at which the specimen was found under bark.

Figures 23–28: Pandinus ugandaensis sp. n. 23–25. ♂ (97 mm) holotype, dorsal and ventral views and pectinal area. 26–28. ♀ (105 mm) allotype, pectinal area and dorsal and ventral views.

Figure 42: Distribution map of the subgenus Pandinus. Localities of P. imperator and P. gambiensis are after Prendini (2004: 255, fig. 13), localities of other species are new records except Hargeysa (type locality of P. smithi). Type locality of P. phillipsii corresponds with new records (Goolis Mts.). Other localities of P. phillipsii and P. smithi cited by older authors (Borelli, 1919; Pocock, 1896, 1897, and 1900) are not included in the map. Exact distributions of these species need to be further investigated.
