Type locality and horizon: Myanmar (Burma), Kachin; precise locality unknown; Lower Cretaceous.</p><p>Patronym. – The specific name honours Mr Dieter Peters (Gelsenkirchen, Germany), who supported the present study.</p><p>Depository. – The type specimen is deposited in the collections of Mr Dieter Peters (Gelsenkirchen, Germany) .</p><p>Diagnosis. – As for most previously described species of Chaerilobuthus, the general morphology of the new species follows the standards defined for the family Chaerilobuthidae . Carapace only weakly emarginated anteriorly; both median and lateral eyes absent; the almost total absence of eyes was only previously observed for Chaerilobuthus birmanicus Lourenço, 2015 . A possible presence of a macula in the place of lateral eyes; characters previously observed only for Chaerilobuthus meggeri Lourenço, 2021 . Pedipalps globally elongated; relationship between chela length vs chela width equal to 6.35 (Lourenço &amp; Velten, 2022); spinoid granules absent from the internal aspect of patella. Pectines are very roughly observed, but appear as rather large with 10-11 teeth, a record among the species of the genus; fulcra absent; sternum approximately pentagonal and conspicuous, slightly longer than wide; genital operculum with two rounded plates; spiracles very small and slightly rounded to semi-oval in shape; cheliceral dentition partially observed; movable finger with two distal teeth; distal teeth of fixed and movable fingers very long and overlapping for about one half of their length; fixed and movable fingers with one basal and one median tooth; vesicle moderately bulbous with a thin and long aculeus. Trichobothrial pattern related to those of buthoids and chaeriloids, recalling types A and B, as defined by Vachon (1974) with at least 2 dorsal and 4 external trichobothria on the femur; 2-3 dorsal, 1 internal and 4-5 external on the patella; 2 dorsal and 3-4 external on chela hand and 5-6 on fixed finger.</p><p>Description</p><p>Coloration. – The scorpion is reddish-yellow to brownish-yellow with some dark reddish zones; carapace, tergites and sternites brownish-yellow; metasomal segments brownish-yellow; telson reddish-brown; pedipalps and legs reddish-yellow. Ventral aspect reddish-yellow; pectines yellow.</p><p>Morphology. – Carapace without granulations; almost smooth; anterior margin with a weak median concavity. Carinae and furrows weak or absent. Median ocular tubercle totally absent; median and lateral eyes equally absent; possible presence of a macula in the place of lateral eyes. Sternum approximately pentagonal and conspicuous, slightly longer than wide. Mesosomal tergites not granular as carapace and with weakly marked carinae; VII with five weakly marked carinae. Pectines are roughly observed, but are large and with 10-11 teeth; fulcra absent; the zone with peg sensillae can be observed on some teeth. Sternites can be roughly observed since they suffered with the dissection process; almost smooth, with small spiracles small and slightly rounded to semi-oval in shape. Metasomal segments I to IV with 10-8-8-8 observable carinae; dorsal without spinoid granules; segment V with five carinae; ventral carinae on segments I-IV weakly marked; setation on segments I to V moderate. Telson with a moderately bulbous vesicle; weakly granular to smooth and a strong setation; aculeus long but moderately curved. Cheliceral dentition partially observed; movable finger with two distal teeth; distal teeth of fixed and movable fingers very long and overlapping for about one half of their length; fixed and movable fingers with one basal and one median tooth (Vachon, 1963). Pedipalps globally elongated; femur pentacarinate with inconspicuous spinoid granules on internal face; patella with dorso-internal, ventro-internal, dorso-external, external and ventral carinae; spinoid granules on internal face inconspicuous or absent. Chela with moderately to weakly marked carinae; all faces weakly granular to smooth; internal face without spinoid granules. Fixed and movable fingers with 6-7 longitudinal rows of small, rounded granules, separated by slightly bigger accessory granules; extremity of fingers with one stronger spinoid granule. Trichobothriotaxy: a trichobothrial pattern related to those of both buthoid and chaeriloids, types A and B can be observed (Vachon, 1974); for details see diagnosis. Leg tarsi with thin ventral setae. Pedal spurs present and weakly marked; tibial spurs absent.</p><p>Morphometric values (mm), holotype of Chaerilobuthus petersi Lourenço sp. n.</p><p>– Total length (including telson) 4.97.</p><p>– Carapace length 0.81,</p><p>anterior width 0.42,</p><p>posterior width 0.54.</p><p>– Mesosoma length 1.57.</p><p>– Metasomal segments</p><p>I: length 0.21, depth 0.21;</p><p>II: length 0.23, depth 0.21;</p><p>III: length 0.27, depth 0.19;</p><p>IV: length 0.37, depth 0.18;</p><p>V: length 0.74, depth 0.17.</p><p>– Telson length 0.77.</p><p>– Vesicle depth 0.17.</p><p>– Pedipalp femur length 0.57, width 0.32;</p><p>patella length 0.75, width 0.24;</p><p>chela length 1.08, width 0.17;</p><p>movable finger length 0.67.</p><p>Relationships. – In account of the total absence of eyes, the new species seems to be related to Chaerilobuthus birmanicus Lourenço, 2015, species with only extremely reduced lateral eyes (Lourenço, 2015). The presence of a possible macula in the place of lateral eyes, associates the new species to C. meggeri Lourenço, 2021 . The new species can however, be distinguished from these two species by a combination of characters: (i) total absence of eyes and/or possible presence of a macula, (ii) anterior margin of carapace weakly emarginated; straight in C. birmanicus, (iii) pedipalps globally elongated, in particular chelae; relationship between chela length vs chela width equal to 6.35 while in C. birmanicus and C. meggeri these values range from 3 to 4 (Lourenço &amp; Velten (2022).</p></div>	https://treatment.plazi.org/id/0C5B0E04FD0BFFAAFF497064FA107531	Public Domain	No known copyright restrictions apply.
