SUMMARY 



The prcsent volume of the Fauna ČSSR series includes hematophagous and endoparasitic 

 flies {Diptera) of 8 families, viz., Ceratopogonidae, Simuliidae, Tabanidae, Hypodermatidae, Oestridae, 

 Gasterophilidae, Hippoboscidae and Nycteribiidae. A systematic list of treated taxa is givcn 

 on p. 000 as an opening chapter of the volume. The species marked with an asterisk (*) háve 

 not yet been found in Czechoslovakia but may be anticipated-there. Altogether 239 species 

 in 49 genera and 8 families are included, of these one species, Prosimulium subrufipes Knoz 

 sp. n. {Dipt., Simuliidae), is described here for the first time; for the description see below. 



Each family is introduced by a generál section which includes a diagnosis, morphology of 

 adults and immature stages (if treated in the systematic part), a phylogeny, Classification and 

 systematic position of the family. In addition there are notes on the origin and composition 

 of species found in Czechoslovakia, and comments of economic and sanitary importancc, 

 such as protection of hosts, and data on natural enemies. 



The systematic part includes Identification keys to subfamilies, genera, subgenera and species 

 found or anticipated to occur in Czechoslovakia. The most important synonymies and literary 

 references are given to each species, followed by a short description, notes on bionomy, ecology 

 and dates of occurrence in Czechoslovakia, notes on hosts, geographical distribution and 

 occurrence in Czechoslovakia. The major differential features are illustrated. Generally only 

 adults are dealt with but, in Simuliidae where the taxonomy is sometimes based predominantly 

 on immature stages, or in gad-flies where the larvae are more often met with in nature than 

 the adults, the descriptions of larvae and pupae are also given. 



Prosimulium subrufipes Knoz sp. n. 



Fig. 61 F, 78 



P. fuscipes v. Roser, 1840 sensu Rubcov, 1959—1964: 179 (partim); Knoz, 1965: 20; 

 Prosimulium sp.? Zwick, 1974: 83. 



A species dosely related to Prosimulium rufipes v. Roser. 



?. Vertical angle of frons about 100°. Tibiae and femora mostly yellowish-brown. Cerci 

 considerably shorter on dorsum than on venter, about 2.5—3 times broader than long. The 

 broadly heart-shaped sternum 7 one and one-half times broader than long. 



cj. Apex of lacinia with a larger number of spines on inner margin and with 3 to 4 spines on 

 outer margin. Scutum, scutellum and the main stem of wing-veins covered with golden-yellow 

 hairs. Gonosternum in posterior view in а form of an isosceles triangle. Body length 3.0—4.0 

 mm. 



Larva is smaller and paler and differs from that of P. rufipes in а mildly blunt apexes of 

 а trifid tooth on frontal margin of hypostomium.
