Morphological features of pupae of Drusus croaticus Marinković-Gospodnetić, 1971 and Drusus septentrionis Marinković-Gospodnetić, 1976 (Insecta: Trichoptera) from Balkan Peaninsula

The major research on Trichoptera in Bosnia and Herzegovina and Croatia started at the turn of the 19th century. Altogether, approximately 35 species are described from Bosnia and Herzegovina and Croatia. Some of these species belong to the genus Drusus Stephens, 1837. Drusus species in Bosnia and Herzegovina and Croatia are distributed from the Dinarides, mountainous area spreading throughout Central Croatia and Bosnia and Herzegovina. Seven species in Bosnia & Herzegovina from the genus Drusus belong to the bosnicus group. All Drusus species in the bosnicus group occurring in Bosnia and Herzegovina are allopatric in distribution. Populations of this species could have been separated due to geological and climatic changes and new allopatric species could eventually evolve. Drusus septentrionis Mar. is distributed in eastern part in Bosnia & Herzegovina in four springs, and Drusus croaticus Mar. is distributed in central mountain part of Croatia in numerous springs. Both species was described by Mara Marinković-Gospodnetić, Professor from the University in Sarajevo, in the second half of XX century. Larvae of these species were described before two years.In this study we present results on morphological features of pupa of Drusus croaticus Mar., collected in spring of the Bijela Rijeka River (National Park “Plitvice Lakes”, Croatia) and pupa of Drusus radovanovici Mar. collected according reared larvae to adults in the laboratory. The larvae of Drusus radovanovici were collected in the spring of the Bistrica River (Bosnia & Herzegovina), and transferred to the laboratory in Zagreb. It was the first described of pupae from any endemic species of genus Drusus from the Balkan Peninsula.
