New synonymies in Sphecodes Latreille, 1804 (Hymenoptera, Apoidea, Halictidae) species from Italy, with taxonomic notes on type material

Abstract

Type specimens of the bee genus Sphecodes Latreille, 1804 (Hymenoptera: Halictidae), described by Vittorio Nobile and Giuseppe Fabrizio Turissi from Italy and deposited in the Zoologische Staatssammlung, München, Germany, were studied. Detailed information on the primary types of the six nominal species and their illustrations are provided. Sphecodes banaszaki Nobile & Turrisi, 2004, syn. nov., S. marcellinoi Nobile & Turrisi, 2004, syn. nov., S. walteri Nobile & Turrisi, 2004, syn. nov., S. iosephi Nobile & Turrisi, 2004, syn. nov., and S. tomarchioi Nobile & Turrisi, 2004, syn. nov., are all synonymized with Sphecodes combai Nobile & Turrisi, 2004, which is rediagnosed. Also accepted synonymy of S. campadellii Nobile & Turrisi, 2004 = S. geoffrellus (Kirby, 1802), previously suggested by M. Schwarz’s and F. Gusenleitner’s (2012).
