Contribution to the Arabo-Saharan psammophilous Saprininae, with descriptions of two new species (Coleoptera, Histeridae, Saprininae, Hypocaccini)

Two new psammophilous Saprininae, Neopachylopus pharkidodes sp. nov. and N. penatii sp. nov. from the Arabian Peninsula and Algerian Sahara, respectively, are described and figured herein. Both are tentatively assigned to the genus Neopachylopus Reichardt, 1926, pending further studies. A key to species is given. The second known exemplar of the very rare Exaesiopus therondi Lackner, 2015 from the United Arab Emirates is reported and figured.
