Diagnosis

The diagnosis provided here is an updated version of the one presented in Carvalho and Kury (2020: 94), as follows: P. littoralis can be distinguished from P. iratiensis and P. longicornis due to: (1) Ocularium with pair of parallel and independent armature (as in P. iratiensis ) ( Carvalho and Kury 2020: fig. 9B); (2) Scutal area III with a pair of paramedian domes ( Carvalho and Kury 2020: figs 8A, C, 9A, C); (3) Fe II unarmed on retrodorsal distal face; (4) Cx IV prodorsal apophysis with less of the AW half-size ( Carvalho and Kury 2020: figs 8A, 9A); (5) Fe IV dorsal face with a comb of spines (iiI) on the proximal half ( Carvalho and Kury 2020: figs 9D–E, G); (6) Fe IV armed with a tiny spine on retrodorsal distal face ( Carvalho and Kury 2020: figs 8A, 9D–E); (7) DS posterior margin and free tergites I– III of females with a row of outstanding acuminated tubercles (as in P. longicornis ) ( Carvalho and Kury 2020: fig. 8D).
