Spinoburmesebuthus pohli Lourenço, 2017

Spinoburmesebuthus pohli Lourenço, 2017 (Family Palaeoburmesebuthidae )

A very small juvenile, measuring a total length of 9.93 mm, included in a clear reddish-yellow piece sizing 26 x 12 x 3 mm. The piece contains vegetal debris and some dirts. The species is clearly characterised by the shape of the telson with an aculeus with a very strong base and the presence of several spinoid granules on the pedipalp chelae ( Figs. 6 View Fig , 12 View Fig ). Two species are known for this genus ( Lourenço, 2021), but the recently described Betaburmesebuthus spinipedis Xuan, Cai & Huang, 2022 , most certainly do belong to the genus Spinoburmesebuthus (Xuan et al., 2022) .
