Figure 12 in Etudes on iurids, II. Revision of genus Calchas Birula, 1899, with the description of two new species (Scorpiones: Iuridae)

Figure 12: Diagrammatic view of pedipalp chela from the finger's perspective showing the eight primary carinae in genus Calchas. This carinal arrangement complies with the "8- carinae" configuration, note the absence of the V2 (ventromedian) and D2 (subdigital) carinae. Dotted portions indicate fixed and movable fingers and socket areas. D1 = digital carina, D3 = dorsosecondary carina; D4 = dorsomarginal carina, D5 = dorsointernal carina, V1 = ventroexternal carina, V3 = ventrointernal carina, E = external carina, I = internal carina. Diagram based on male C. nordmanni.
