Annotated type catalogue of the Chrysididae (Insecta, Hymenoptera) deposited in the collection of Maximilian Spinola (1780-1857), Turin.

A critical and annotated catalogue of the ninety-six type specimens of Chrysididae (Hymenoptera), belonging to sixty-seven species, housed in the insect collection of Maximilian Spinola is given. The neotypes of six species are designated: Chrysisbicolor Lepeletier, 1806; Chrysiscomparata Lepeletier, 1806; Chrysisdives Dahlbom, 1854; Chrysispumila Klug, 1845; Chrysissuccincta Linnaeus, 1767; Hedychrumbidentulum Lepeletier, 1806. The lectotypes of twenty-four species are designated: Chrysisaequinoctialis Dahlbom, 1854; Chrysisanalis Spinola, 1808; Chrysisassimilis Dahlbom, 1854; Chrysisbihamata Spinola, 1838; Chrysischilensis Spinola, 1851; Chrysisdichroa Dahlbom, 1854; Chrysisdistinguenda Dahlbom, 1854; Chrysisepiscopalis Spinola, 1838; Chrysisgrohmanni Dahlbom, 1854; Chrysisincrassata Spinola, 1838; Chrysispallidicornis Spinola, 1838; Chrysispulchella Spinola, 1808; Chrysisramburi Dahlbom, 1854; Chrysisrefulgens Spinola, 1806; Chrysissplendens Dahlbom, 1854; Chrysissuccinctula Dahlbom, 1854; Chrysisversicolor Spinola, 1808; Elampusgayi Spinola, 1851; Hedychrumcaerulescens Lepeletier, 1806; Hedychrumchloroideum Dahlbom, 1854; Hedychrumdifficile Spinola, 1851; Hedychrumvirens Dahlbom, 1854; Holopygajanthina Dahlbom, 1854; Holopygaluzulina Dahlbom, 1854. Previous lectotype designations of five species are set aside: Chrysisbicolor Lepeletier, 1806 (designated by Morgan 1984); Chrysiscalimorpha Mocsáry, 1882 (designated by Móczár 1965); Chrysiselegans Lepeletier, 1806 (designated by Bohart (in Kimsey and Bohart 1991)); Hedychrumchloroideum Dahlbom, 1854 (designated by Kimsey 1986); Hedychrumrutilans Dahlbom, 1854 (designated by Morgan 1984). Three new synonymies are proposed: Hedychrumintermedium Dahlbom, 1845, syn. n. of Holopygafervida (Fabricius, 1781); Chrysissicula Dahlbom, 1854, syn. n. of Chrysiselegans Lepeletier, 1806; Chrysissuccinctula Dahlbom, 1854, syn. n. of Chrysisgermari Wesmael, 1839. Chrysisdistinguenda Spinola, 1838, and Chrysiscoronata Spinola, 1808, are considered nomina dubia. Hedychrumalterum Lepeletier, 1806, and Hedychrumaulicum Spinola, 1843, are considered nomina oblita. Hedychrumrutilans Dahlbom, 1854, and Hedychrumniemelai Linsenmaier, 1959, are retained as nomina protecta. The first available name for Chrysissuccinctula sensu Linsenmaier is Chrysistristicula Linsenmaier, 1959, (stat. n.) The current status and validity of some types in the Spinola collection are discussed. Photographs of fifty-three types are given.
