03D55509BD37FF8C3756CEC0FB443C67.taxon	description	Description Coloration. – Globally brown to reddish-brown, with some zones slightly darker; it is uncertain however if this colour pattern is original or an artefact due to the preservation. Morphology. – Prosoma: anterior margin of carapace weakly convex; tegument rather smooth with some vestigial carinae and furrows. Median ocular tubercle conspicuous and slightly anterior to the centre of the carapace; median eyes separated by about one ocular diameter; two pairs of lateral eyes can be observed. Mesosomal tergites rather smooth with one vestigial median carina. Tergites VI and VII with some weak carinae. Sternites not observable. Pectines not observable. Metasomal segment with strongly marked dorsal and sub-dorsal carinae; ventral carinae probably absent with a ventral aspect smooth. Telson smooth; vesicle with a round shape, flattened dorso-ventrally; aculeus slightly curved and shorter than vesicle; subaculear tooth absent. Chelicerae bulk with only a few teeth observable (Vachon, 1963). Pedipalps rather bulk, with chelahand globular and chela-fingers short; femur probably pentacarinate; patella and chela with vestigial. Trichobothrial pattern extremely incomplete but recalling a possible ‘ basic’ type C (Vachon, 1974). Chela manus with 2 - 3 trichobothria, Db, and 2 Eb. Patella with d 1, d 2, and i. Femur with d, i and e (Fig. 7 - 8). Dentate margins of fixed finger probably composed of a single linear row of granules. Legs: Ventral aspect of tarsi and spurs not observable. Morphometric values (mm) of the holotype of Protochactas furreri sp. n. – Total length (including telson) 27.0. – Carapace: length, 3.1; anterior width, 2.9; posterior width, 3.5. – Mesosoma: length, 6.8. – Metasomal segments I: length, 1.8; width, 2.0; II: length, 2.1; width, 1.9; III: length, 2.2; width, 1.8; IV: length, 2.4; width, 2.4; V: length, 3.0; width, 2.4. – Telson: length, 3.1; width, 1.1. – Pedipalp (right / left) femur length, 2.8 / 2.7, width, 1.1 / 1.0; patella length, 2.5 / 2.5, width, 1.1 / 1.3; chela length, 5.3 / 5.4, width, 2.4 / 2.0; movable finger length, 3.3 / 3.5.	en	Magnani, Fabio, Stockar, Rudolf, Lourenço, Wilson R.

03D55509BD37FF8C344BCFA5FE53331A.taxon	diagnosis	Diagnosis for the new family Scorpion of small size with 27.0 mm in total length. The holotype is most probably an adult or pre-adult. Body and appendages rather bulk. Carapace rather smooth with the anterior margin slightly convex; presence of some vestigial carinae and some shallow furrows; median ocular tubercle conspicuous and slightly anterior to the centre of the carapace; median eyes moderate in size and separated by less than one ocular diameter; two pairs of conspicuous lateral eyes. Mesosomal tergites rather smooth with one vestigial median carinae; some weak carinae present on tergites VI and VII. Metasomal segments with strongly marked dorsal and sub-dorsal carinae; ventral carinae apparently absent. Telson with a globular vesicle, almost rounded and flattened dorso-ventrally; aculeus shorter than the vesicle and weakly curved; subaculear tubercle absent. Ventral characters are not observable. Trichobothrial pattern extremely incomplete, and only a few bothria can be detected; these suggest the fundamental type C (Vachon, 1974). The following trichobothria can be observed: 2 - 3 dorso-external on chela manus, namely Db, and two Eb; 2 dorsal and one internal on patella; 1 dorsal, 1 external and 1 internal on femur. Dentate margins of fixed finger probably composed of a single linear row of granules. Chelicera poorly observable, but 2 - 3 teeth on fixed finger and 3 - 4 on movable finger can be suggested (Vachon, 1963). Legs: tibial spurs not observable.	en	Magnani, Fabio, Stockar, Rudolf, Lourenço, Wilson R.
