Characters of Siphloplecton of unclear phylogenetic status. (1) Larval abdominal terga and sterna have spine-like setae (unlike Metretopus/fg2 and Metreplecton). (2) All tergalii, including IV–VII [see Metretopus/fg1 (3)], lack denticles (unlike Metretopus/fg2 and Metreplecton); only spine-like setae can be present. (3) Distal segment of labial palp [2nd+3rd – see Metretopus/fg1 (2)] is widest near apex. The same in Metreplecton, probably synapomorphy. (4) Cubital field of fore wing usually with 4 intercalaries forming 2 pairs, among which the posterior pair arise more proximally and is the longest; in each pair the anterior intercalary (nearest to convex CuA) is concave, and the posterior intercalary (nearest to concave CuP) is convex; selected specimens have 3 intercalaries only [see Metretopus/fg1 (5)] (Berner 1978: Fig.1-5). Non-unique apomorphy; the same in Heptagennota (see Index of characters [2.2.52]). |
Size. Fore wing length 9–16 mm.
Distribution. Nearctic; in fossil condition known from Palaearctic.
