Morphological separation of fifth instar larvae of Apataniidae Wallengren 1886 from other European Trichoptera

Larvae of the family Apataniidae share the folloWing morphological characters ( Pitsch 1993; Solem 1985; Wallace et al. 2003; Waringer & Graf 2011; Wiggins 1996):

- With transportable case ( Fig. 14 );

- sclerites present on pro-, meso-, and metanota ( Fig. 5 , p, ms, mt);

- no transverse rim at anterior 3rd of pronotum ( Fig. 4 , arroW);

- pronotum and mesonotum each completely covered by 2 sclerites in close contact, separated by unbranched longitudinal suture ( Fig. 5 , arroWs);

- median(sa 1) and posterior metanotal sclerites (sa 2) reduced and represented only by setal groups ( Fig. 5 );

- prosternal horn present ( Fig. 2 , ph);

- antennae situated halfWay betWeen eye and anterior head margin ( Fig. 1 , arroW);

- scraper-type mandibles Without terminal teeth along cutting edge ( Fig. 2 , arroW);

- submentum Wedge-shaped ( Fig. 2 , s);

- head With many secondary setae ( Fig. 3 , ss);

- fleshy protuberances present laterally and dorsally on abdominal segment I ( Fig. 9 , dp, lp);

- all gills consisting of single filaments ( Fig. 9 , dr, do).
