The Emperor is back – the holotype of Pandinus imperator 45 The dimensions specified by Koch (1841) are as follows: head: 10 ½ ’’’ = 23.69 mm, body: 24 ’’’ = 54.14 mm, tail: 36 ’’’ = 81.21 mm, rendering a total length of 159.04 mm; Koch also reported the total length to be almost 6 ’’ = <162.4 mm (or 175.12 mm when using the Bavarian decimal Zoll). Recent measurements: prosoma: 22.8 mm, mesosoma: 56.4 mm, metasoma and telson: 81.7 mm (i.e., including ve- sicle and aculeus, with the length of the first segment interpo- lated); total length: 160.9 mm (measured by a vernier calliper, in view of the fact that the telson is coiled up; see Fig. 3).
