Type specimens from the insect collections deposited in the Department of Entomology, National Museum, Prague, are currently being catalogued. In this part of the catalogue we deal with Hemiptera: Sternorrhyncha. This group is namely represented in the museum by the whitefl y collection of Jiří Zahradník and the scale insect collections of Jiří Zahradník and Josef Řeháček, while the psyllid material was mostly collected by Jiří Dlabola and other workers of the department and identifi ed by Marianna M. Loginova, Daniel Burckhardt and Pavel Lauterer (material from the expeditions of the National Museum to Iran in 1970s is particularly numerous and scientifi cally valuable). We list the types of 36 taxa (3 in Aleyrodomorpha, 3 in Coccomorpha, and 30 in Psyllomorpha), including holotypes or syntypes of 14 taxa (3 in Aleyrodomorpha, 2 in Coccomorpha, and 9 in Psyllomorpha)
