Autapomorphies of Glossiodion. () Labium [see Turbanoculata (7)] is modified: paraglossae are widened and glossae are diminished (similar to Labiobaetis/f2=g1); 2nd segment of labial palp [initially widened - see (?)] is secondarily narrowed (Lugo-Ortiz & McCafferty 1988: Fig9). () Denticles on posterior margins of larval abdominal terga and sterna [see (?)] are lost on most segments, but present on 10th tergite and paraprocts. Characters of Glossiodion of unclear phylogenetic status. () Median sterno-styligeral muscle is lost (see Index of characters [2.3.7]) ... Plesiomorphies of Glossiodion. ... |
