ABSTRACT

The pleasing lacewing genus Dilar Rambur, 1838, is the only known representative of the family Dilaridae from Central Asia. Here we present a review of the five species of Dilar from Central Asia, Dilar hornei McLachlan, 1869, Dilar caesarulus H. Aspöck U. Aspöck, 1967, Dilar kirgisus H. Aspöck U. Aspöck, 1967, Dilar vartianorum H. Aspöck U. Aspöck, 1967, and Dilar dochaner H. Aspöck U. Aspöck, 1968. Remarkable intraspecific variations in male gonocoxite 10 are found in D. kirgisus and D. vartianorum. Re-descriptions of all the species are provided. Dilar indicus Monserrat, 1989, and Dilar similis Monserrat, 1989, are synonymized with D. vartianorum. A key to the species of Dilar from Central Asia is provided.
