Descriptions of the larvae and pupae of Sisko Ross with notes on western Dolophilodes Ulmer larvae (Trichoptera: Philopotamidae) Author Lee, Jonathan text Zootaxa 2024 2024-03-20 5428 1 124 134 http://dx.doi.org/10.11646/zootaxa.5428.1.6 journal article 10.11646/zootaxa.5428.1.6 1175-5326 10843052 C34F72D5-D271-4C14-ADFB-6AF94BC6A441 Key to Larvae of North American Philopotamidae Genera. The following key is modified from that of Morse et al. (2019) . Figures 19.360 –19.366 refer to those of Morse et al. (2019) ; figures 8.1A–8.1C, 8.1F, 8.2B– 8.2E , 8.3C– 8.3E refer to those of Wiggins (1996) ; figure 1B refers to that of Weaver et al. (1981) . Figures 1–12 are original in this paper. The larvae of the purported eastern population of Sisko are currently unknown. 1 Prothoracic coxae each with long slender, subapicodorsal process bearing apical seta (figs 19.364, 8.1C); foretrochantins small and scarcely projecting (fig. 8.1A); anterior margin of frontoclypeus with prominent notch, typically asymmetrically right of midline (fig. 8.1B); head with setae number 18 at level of posterior point of ventral apotome (figs 19.365, 8.1F); widespread..................................................................................... Chimarra Stephens - Prothoracic coxae without long subapicodorsal processes; foretrochantins small and not projecting (figs 8.3D, 8.3E ) or elongate and finger-like (figs 19.363; 8.2C, 8.2D); anterior margin of frontoclypeus variable, prominently notched, slightly sinuous, or completely symmetrical; head with setae number 18 approximately halfway between posterior point of ventral apotome and occipital foramen (figs 19.366; 8.2E , 8.3C)................................................................. 2 2 Foretrochantins small, scarcely projecting (figs 8.3D, 8.3E ); anterior margin of frontoclypeus symmetrical, most commonly slightly convex (figs 19.362; 8.3B) or slightly concave, but can have a central emargination or be distinctly crenulate; widespread........................................................................ Wormaldia McLachlan - Foretrochantins projecting, finger-like (figs 19.363; 8.2C, 8.2D; Fig. 6 ); anterior margin of frontoclypeus variable........ 3 3 Anterior margin of frontoclypeus symmetrical or asymmetrically concave on right (figs 19.361; 8.2B; Figs 9–12 ); if small notch associated with asymmetry, then mandibles with crenulate lateral margins ( Fig. 9 ); widespread........ Dolophilodes Ulmer - Anterior margin of frontoclypeus with distinct notch (fig. 19.360; Figs 1–4 ); mandibles without crenulate lateral margins... 4 4 Anterior margin of frontoclypeus with distinct notch on right (figs 19.360; 1B); larval length to 15 mm ; Southeast U.S. (mountains)....................................................................... Fumonta major (Banks) - Anterior margin of frontoclypeus with distinct notch central (most common) or with notch left or right of center ( Figs 1–5 ); larval length to 7 mm ; Western U.S. ..............................................................
