Type species. – Paranotaburmesebuthus schmidti Lourenço sp. n.

Diagnosis for the new genus. – The general morphology shows several characteristics also present in the other three genera of the family Palaeoburmesebuthidae , but equally in a number of extant buthoid scorpions.A combination of characters can be used to diagnose the new genus from the other buthoid genera previously found in Burmite: A small global size compared to the other genera of the family Palaeoburmesebuthidae with a total length of 10.85 mm, for what can be presumed as an adult male. The specimen is moderately slender with shorter metasoma, telson and pedipalps when compared to other species of Palaeoburmesebuthidae . Carapace moderately granulated; anterior margin with a weak to moderate emargination; posterior median carinae terminating distally in a small spinoid process that extends beyond the posterior margin of the carapace (as in some extant buthids:e.g. Compsobuthus Vachon, 1949 ). Sternum semi-pentagonal. Tergites with one median carina and two strongly marked lateral carinae;tergites I and II with two additional lateral carinae,weakly marked, recalling those of the genus Leiurus Ehrenberg,1828 . Presence in tergites I to VI of lateral extensions recalling small paranota. Sternites almost smooth with small rounded spiracles. Metasomal segments I to III with 10 carinae; segment IV with 8carinae; segment V with 5 carinae; telson moderately long with only some minute spinoid granules; subaculear tooth absent; setation on metasomal segments moderately to strongly marked. Fixed and

movable fingers of pedipalp chela with 9-10series of rounded granules separated by more conspicuous accessory granules. Genital operculum formed by two oval-plates.Pectines short and bulk with 12-11 teeth; fulcra absent. Trichobothrial pattern similar to those of extant buthid type A ( Vachon 1974); the dorsal trichobothria of femur in alpha disposition (Vachon,1975).At least 4 internal, 2 external andfive dorsal trichobothria can be observed in the femur; 1 internal and 5 dorsal trichobothria on patella; ventral totally absent;most external trichobothria canbe suggested on patella bythe presence of fine setae;5-6 dorsoexternal and two ventral on chelal hand and 6 on fixed finger can clearly be observed. Tibial spurs present on legs III and IV;reduced on III.

Etymology. – The new generic name refers to the presence of lateral extensions in tergites, recalling paranota, in association with Burma and the genus Buthus Leach, 1815 .
