The following combination of characters can be used to diagnose the new species. Sternum sub-pentagonal. Tergites with three carinae, the lateral one rather inconspicuous; granulation moderately to weakly marked. Sternites with small, oval to rounded spiracles. Metasomal segments I and II with 10 carinae; III-IV with 8 carinae; V with 5 carinae; setation on all metasomal segments moderately marked. Telson granular, without a subaculear tubercle. Pectines large and long, with 18-x teeth. Trichobothrial pattern can be globally observed, with elements clearly fitting those of extant buthid type A (Vachon, 1974). Femur with 5 dorsal, 2 external and 4 internal trichobothria disposed in alpha (α) configuration (Vachon, 1975); external trichobothria in a very marked proximal position with e 2 at the same level as d 5. Patella with one internal and 5 dorsal trichobothria; 5-6 external trichobothria are suggested by the presence of fine setae; chelal trichobothria well observable: chela hand with Eb 1-3, Esb, Est, Et; fixed finger with eb, esb, est, et, db, dt; it not observable. Tibial spurs present on legs III and IV, moderately marked.</p><p>Type locality and horizon. – Myanmar (Burma), Kachin; precise locality unknown; Lower Cretaceous .</p><p>Patronym. – The specific name honours Mrs Sarah Meyer (Wangenried, Switzerland), who supported, together with Mr Andrè Schmidt, the present study.</p><p>Depository. – The type specimen is deposited in the collections of Mr Andrè Schmidt (Zofingen, Switzerland) .</p><p>Description</p><p>Coloration. –Yellow to slightly reddish-yellow; carapace and tergites yellow; metasomal segments reddish-yellow; telson dark reddish; aculeus reddish; pedipalps and legs yellow to pale yellow. Ventral aspect yellow; pecten yellow to reddish-yellow.</p><p>Morphology. – Carapace elongated; anterior margin slightly concave; ocular tubercle anterior to the centre of the carapace; three lateral eyes; carinae, granulations and furrows moderately to weakly marked. Sternum sub-pentagonal. Mesosomal tergites moderately to weakly granular, with one median carina and two very inconspicuous lateral carinae; VII with five moderately to strongly marked carinae. Pectines: only one pecten is observable with 18 teeth; fulcra inconspicuous. Sternites weakly granular to smooth, with small, oval to almost rounded spiracles. Metasomal segments I to IV slightly rounded, with 10-10-8-8 carinae; segment V slender, with five carinae; dorsal carinae of segments I-IV with only minute spinoid granules; dorsal aspect of segments I to V weakly depressed; setation on all segments moderately marked. Telson with a long, slim pear-shaped vesicle;</p><p>moderately granular, with vestigial ventral and lateral carinae; absence of any subaculear tubercle; aculeus very long and weakly curved; setation weakly marked. Cheliceral dentition similar to that of buthoids (Vachon, 1963). Pedipalp femur pentacarinate; patella with 6-7 carinae; internal face of femur and patella with only minor spinoid granules. Chela slender and not granular with weak carinae. Setation of pedipalps almost absent. Trichobothriotaxy similar to type A (Vachon, 1974) of extant buthids: dorsal trichobothria of femur disposed in alpha (α) configuration (Vachon, 1975); for details refer to diagnosis. Tibial spurs present on legs III and IV, moderately marked.</p><p>Morphometric values (mm) of male holotype of Palaeoburmesebuthus sarahmeyerae Lourenço sp. n.</p><p>– Total length 10.62 (including telson).</p><p>– Carapace length 1.34;</p><p>anterior width 0.74;</p><p>posterior width 1.07.</p><p>– Mesosoma length 2.81.</p><p>– Metasomal segments</p><p>I: length 0.73, width 0.47;</p><p>II: length 0.81, width 0.41;</p><p>III: length 0.87, depth 0.41;</p><p>IV: length 1.05, depth 0.37;</p><p>V: length 1.47, depth 0.34.</p><p>6-7.
