Catalogue of type specimens of true bugs (Hemiptera: Heteroptera) deposited in the National Museum, Prague, Czech Republic. Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha

Abstract: Type specimens from the collection of true bugs (Hemiptera: Heteroptera) deposited in the Department of Entomology, National Museum, Prague, are currently being catalogued. In this part of the catalogue dealing with the five basal infraorders, Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha, we present precise information about the types of 166 taxa belonging to the families Enicocephalidae (2 taxa), Schizopteridae (1 taxon), Nepidae (4 taxa), Gelastocoridae (1 taxon), Corixidae (4 taxa), Micronectidae (7 taxa), Naucoridae (4 taxa), Potamocoridae (1 taxon), Aphelocheiridae (4 taxa), Notonectidae (2 taxa), Helotrephidae (6 taxa), Mesoveliidae (1 taxon), Hebridae (7 taxa), Hydrometridae (5 taxa), Macroveliidae (1 taxon), Veliidae (66 taxa), Gerridae (28 taxa), Saldidae (20 taxa), and Leptopodidae (2 taxa), including holotypes (or dissected parts of holotypes) of 42 taxa, and neotype of one taxon. The correct spelling of Brachymetra anduze Drake & Harris, 1942 and Naboandelus bergevini pygmaeus Linnavuori, 1971 (both Gerridae) is fixed.
