2.3. New data on the distribution of Drusus schmidi in Croatia

The third species, D. schmidi Botosaneanui, 1953, was recorded during this research at four localities in the area of the Papuk Mt. and at one locality in the area of the Krndija Mt. in the continental-lowland part of Croatia (Figure 4). Previous research has recorded this species in the Papuk Mt. area at two locations, the Dubočanka Stream and the Jankovac Spring (Previšić et al. 2013), and our research has significantly expanded its distributional range in Croatia (Figure 4). Morphological identification of larvae was also confirmed by DNA barcoding (Table 2). Analysis of DNA barcoding data indicated an association of larvae and adults of D. schmidi, which has not been done so far. Adult forms of both males and females are well known (Malicky 2004), and for morphological characteristics of larva there are only preliminary data (Waringer et al. 2015) because the description of the larva has only recently been completed (Kučinić et al. in prep.). D. schmidi belongs to the group of so-called "yellow" caddisflies (at the adult stage). Unlike the "black" caddisflies from the Drusus bosnicus Group, which are active during the day and have smaller distributions (Kučinić et al. 2014), “yellow” caddisflies have a more pronounced flight and are active at night. In a certain number of “yellow” caddisfly species, significantly larger distributional areas have been recorded (Marinković- Gospodnetić 1979; Pauls et al. 2006; Previšić et al. 2009) compared to microendemics of the Drusus bosnicus Group (Kučinić et al. 2014; Marinković- Gospodnetić 1979).
