Description of the larva of Holocentropus insignis Martynov 1924 (Trichoptera: Polycentropodidae) with notes on biology and distribution

Abstract

The hitherto undescribed larva of Holocentropus insignis Martynov 1924 was collected in Denmark, the Netherlands, and Finland. Based on larval morphology and DNA association with adults, we were able to distinguish the larva of H. insignis from other Holocentropus species known to occur in Europe and confirm its identification. We provide morphological features to separate H. insignis from the other known species within the genus and give an updated key to all known European larvae of Holocentropus. Extensive notes on the life cycle, biology, and distribution of H. insignis are given.

“…Despite initial skepticism from national funding agencies, FinBOL has delivered primary research results of the very type traditionally supported by them. Deliverables to date include insights into the protein structure of the barcode region (Pentinsaari et al, 2016), species interactions (Kaartinen et al, 2010; Mutanen, Ovaskainen, et al, 2020; Nyman et al, 2015; Rytkönen et al, 2019; Vesterinen et al, 2013, 2016), taxonomy (Boonstra et al, 2018; Haarto & Ståhls, 2014; Hausmann et al, 2013; Huemer et al, 2020; Huemer & Mutanen, 2015; Ivanov et al, 2018; Kirichenko et al, 2016; Kozlov et al, 2017; Landry et al, 2013; Landvik et al, 2013; Lee et al, 2020; Liston et al, 2019; Mutanen, Aarvik, Huemer, et al, 2012; Mutanen et al, 2012, 2013, 2015, 2016, 2020; Nieminen et al, 2018; Pentinsaari et al, 2014; Pentinsaari et al, 2014; Pilipenko et al, 2012; Pohjoismäki & Haarto, 2015; Pohjoismäki et al, 2016; Prous et al, 2016, 2020; Pykälä & Myllys, 2016; Salmela et al, 2014; Sihvonen et al, 2020; Ståhls et al, 2015; Tabell et al, 2019; van Nieukerken et al, 2012; Wikström et al, 2020; Wilson et al, 2011), phylogenetics (Heikkilä et al, 2014; Kaila et al, 2020; Karsholt et al, 2013), faunistics (Korpelainen & Pietiläinen, 2017; Paukkunen & Kozlov, 2015), biogeography (Huemer et al, 2014, 2018; Mutanen, Hausmann, et al, 2012; Salmela, 2012), methodology (Kekkonen et al, 2015; Korpelainen & Pietiläinen, 2...…”
