Tetramerotarsata Liberevenata Turbanoculata
Anteropatellata Baetovectata Baetungulata Baetodes/g1 - Baetodes/g2)
Nomen hierarchicum: Baetodes/g2 [g:1924] (sine Indobaetis, Prebaetodes; incl. Indobaetodes)
In circumscription fits:
Autapomorphies of Baetodes/g2.
(1) Patella-tibial suture [equally developed on all legs – see Anteropatellata (1)] goes by anterior (dorsal) side of tibia exactly along tibia and has a form of light line on dark background; distally from the middle of tibia this suture has its usual oblique direction (Kluge & Novikova 2014: Fig.67–68). In Baetodes/g3 it undergoes further modification [see below, Baetodes/g3 ()].
Non-unique autapomorphies of Baetodes/g2.
() Larva is adapted to inhabit in rapid waters, with this are connected some unique apomorphies [see ()–()], as well as non-unique ones: body Acentrella-like, i.e. with flattened ventral and convex dorsal side, thorax relatively large in comparison with abdomen (non-unique character – see Index of characters [1a]); paracercus is vestigial, consists of several segments (non-unique character – see Index of characters [1.3.64]); cerci are long, swimming setae are short or lost.
(?) Tergalial ribs [initially situated on anterior and posterior margins – see Tetramerotarsata (12)] are lost.
Characters of Baetodes/g2 of unclear phylogenetic status.
Plesiomorphies of Baetodes/g2.
Size. Fore wing length 2.5–8 mm (see Tetramerotarsata).
