7E4C87CDFFF8FFE8FC9A77ACFD68F9E2.taxon	diagnosis	Diagnosis for the new species. – General morphology similar to that of other species of the genus Palaeoburmesebuthus Lourenço, 2002, but showing more similarities with Palaeoburmesebuthus knodeli Lourenço, 2018. 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.	en	Lourenço, Wilson R., Velten, Jürgen (2025): A particular new species for the genus Palaeoburmesebuthus Lourenço, 2002 from Burmite (Scorpiones: Palaeoburmesebuthidae).

7E4C87CDFFF8FFE8FC9A77ACFD68F9E2.taxon	description	Description 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. 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; 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. Morphometric values (mm) of male holotype of Palaeoburmesebuthus sarahmeyerae Lourenço sp. n. – Total length 10.62 (including telson). – Carapace length 1.34; anterior width 0.74; posterior width 1.07. – Mesosoma length 2.81. – Metasomal segments I: length 0.73, width 0.47; II: length 0.81, width 0.41; III: length 0.87, depth 0.41; IV: length 1.05, depth 0.37; V: length 1.47, depth 0.34. 6 - 7. Habitus. 6. Dorsal aspect. 7. Ventral aspect. 8. Carapace and pedipalps in detail. 9. Metasomal segments and telson in detail. – Telson length 1.54. – Vesicle depth 0.21. – Pedipalp femur length 1.14, width 0.21; patella length 1.21, width 0.27; chela length 2.14, width 0.21; movable finger length 1.54. Relationships. – The new species can be distinguished from the other species of the genus and in particular from P. knodeli by the following characters: (i) very elongated telson without a subaculear tooth, (ii) spiracles almost round, (iii) trichobothria e 2 and d 5 of the femur situated at the same level.	en	Lourenço, Wilson R., Velten, Jürgen (2025): A particular new species for the genus Palaeoburmesebuthus Lourenço, 2002 from Burmite (Scorpiones: Palaeoburmesebuthidae).
