Autapomorphies of Sparsorythus. (1) Maxillary palp [muscle-less – see Ephemerella/fg1 (1), elongated – see Tricorygnatha (1)] is completely lost. Non-unique apomorphy (see Index of characters [1.1.41]), but not found in other Tricorygnatha. As larvula of Tricorygnatha has no maxillary palp [see Tricorygnatha (1)] (Kluge 2010: Fig.33), and in all cases maxillary palp is muscle-less, the loss of maxillary palp can be repeatable. (2) Genitals of all known species have similar structure: penis narrow, with slightly widened apical part, with apical cleft very small; 1st segment of gonostylus relatively short (Kluge 2010: Fig.81-82). |
Size. Larval body length 3–8 mm.
Distribution. Oriental Region.
