Palaeopolistes jattioti Perrard , sp. nov.

( Figs. 1 , 2 )

Material examined. Holotype, MNHN.F. A50409 (Nel leg.), paratype, MNHN.F.A50410 (Jattiot R. leg.), deposited in the laboratory of Palaeontology, MNHN, Paris.

Etymology. Named after Romain Jattiot who discovered the paratype and gave it to us for study.

Diagnosis. As for the genus.

Description. Female/worker: Head dark with light marks on frons and behind eyes. Pronotum dorsally dark, light ventrally. Mesonotum dark with two longitudinal light lines. Mesepisternum with dark and light marks. Scutellum and metanotum dark. Propodeum dark with two extensive lateral light marks. First mestasomal segment elongated, enlarged in its posterior half, dark with two light marks. Second metasomal tergum light with an anterior and a middle dark bands joining laterally. Terga two to six light with anterior dark bands.
