Key to the Subfamilies of Scorpionidae Latreille, 1802

1. Stridulatory organs, comprising a “rasp” (granular tubercles) and “scraper” (stridulatory setae or scaphotrix), present on opposing surfaces of coxae of pedipalps and first pair of legs; counts of pro- and retroventral spiniform macrosetae similar on telotarsi I and II andonIIIandIV.......................... 2

– Stridulatory organs absent from opposing surfaces of coxae of pedipalps and first pair of legs; counts of pro- and retroventral spiniform macrosetae increasing from telotarsi I andIItoIIIandIV......................... 3

2. Pedipalps orthobothriotaxic, with 26 trichobothria (patella with 13 trichobothria in e series and 3 trichobothria in v series; chela with 4 trichobothria in V series and 2 trichobothria in i series); granular tubercles of “rasp” and stridulatory setae (scaphotrix) of “scraper” situated on coxae of first leg and pedipalp, respectively........................ Heterometrinae Simon, 1879 , stat. nov.

Pandininae Thorell, 1876

3. Pedipalps neobothriotaxic, with more than 26 trichobothria (patella with more than 13 trichobothria in e series and often more than 3 trichobothria in v series; chela rarely with more than 4 trichobothria in V series); cheliceral coxae usually with stridulatory setae (scaphotrix) on prodorsal surfaces and chemoreceptive lamelliform setae (trichocopae) on promedian surfaces..................... Opistophthalminae Rossi, 2016 , stat. nov.
