Chaetopteryx bucari sp. n., a new species from the Chaetopteryx rugulosa group from Croatia (Insecta, Trichoptera, Limnephilidae) with molecular, taxonomic and ecological notes on the group

Abstract

We describe a new autumnal caddisfly species Chaetopteryx bucari sp. n. from 8 localities in the Banovina region of Croatia. We also present molecular, taxonomic and ecological notes (emergence, sex ratio and seasonal dynamics) on the new species and discuss the distribution of Chaetopteryx species in general and the Chaetopteryx rugulosa group in particular. Based on Bayesian phylogenetic analysis Chaetopteryx rugulosa schmidi was separated from the clade containing the other subspecies of Chaetopteryx rugulosa. Thus the subspecies Chaetopteryx rugulosa schmidi is here raised to species level, Chaetopteryx schmidi, as it was described originally. We further present distribution data on rare species in the genus Chaetopteryx in Croatia.

First systematic investigation of adults and second checklist of caddisflies of the Plitvice Lakes National Park with notes on research history, biodiversity, distribution and ecology

“…Some other groups of aquatic insects confirm that, too (Ivković et al, 2013a(Ivković et al, , 2015Kvifte et al, 2013). These results enabled the descriptions of Berdeniella keroveci Kvifte & Ivković (Diptera, family Psychodidae) (Kvifte et al, 2013) which might be the first such case in Europe, as well as the description of C. bucari Kučinić, Szivák & Delić from Banovina (Kučinić et al, 2013).…”

Žalac & A. Delić unpublished data) and Bosnia and Herzegovina (spring Bistrica in Livno, M. Kučinić, S. Žalac unpublished data).…”

“…Additionally, species from the family Glossostomatidae were restricted to the same aquatic habitats (crenal part of streams) while, for instance, Tinodes unicolor Pictet is a specialist at tufa barriers (Edington & Hildrew, 1995). Chaetopteryx bucari Kučinić, Szivák & Delić and many other species from the genus Chaetopteryx (including C. fusca Brauer and C. gonospina Marinković-Gospodnetić found at the Plitvice Lakes) have adaptations to small streams and springs (Kučinić et al, 2013;Szivák et al, 2017) while E. tenellus Rambur is a well known specialist of large rivers and lakes, like most species of family Hydroptilidae and Limnephilidae, for instance (Hickin, 1967;Graf et al, 2008b). Ecological speciation (Nosil, 2012) is a very important process for speciation, evolution and biodiversity of life on Earth, including also freshwater organisms (Pauls et al, 2008).…”

Annotated checklist of Croatian riffle beetles (Insecta: Coleoptera: Elmidae)

“…Therefore, just like with other groups of insects, e.g. caddisflies or moth flies (Kučinić et al, 2013(Kučinić et al, , 2014Kvifte et al, 2013;Previšić et al, 2013), the number of water beetle species is expected to increase with future investigations. As for Elmidae, two additional taxa, Elmis syriaca zoufali (Kuwert 1890) and Stenelmis puberula Reitter 1887, are likely to be found in Croatia since both are known from Bosnia and Herzegovina.…”

First record of Beraea dira McLachlan 1875 (Insecta, Trichoptera, Beraeidae) in Croatia

“…Plitvice Lakes National Park, the Cetina river, the Dobra river, the Krka river). In this period several new species and subspecies have been discovered (Previšić et al, 2014;Kučinić et al, 2013;Oláh, 2010Oláh, , 2011Malicky et al, 2007;Kučinić & Malicky, 2002). Caddisfly females (Kučinić et al, 2014;Vučković et al, 2011) and larvae (Previšić et al, 2014;Waringer et al, 2009;Graf et al, 2008b;Kučinić et al, 2008) have been described from specimens collected in Croatia.…”
