Two new species of Naddia Fauvel (Coleoptera: Staphylinidae: Staphylininae) and creation of the N alexeyi species group

In the present paper, we describe the Naddia alexeyi species group and define it based on the following synapomorphic characters: pronotum with sharp anterior angles; pronotal hypomeron setose; middle area of male sternite 7 with an arc-shaped cluster of setae; paramere of the aedeagus strongly reduced and divided into two parts weakly connected by a membranous area. Two new species are described within this group: N. alexeyi sp. nov. (Laos and Vietnam) and N. tangi sp. nov. (South India). Habitus and aedeagus photos are given for both species.
