Genus Similicloeon Kluge & Novikova 1992

= Intercloeon Kluge & Novikova 1992, syn. n.

Hierarchical name: Similicloeon /g1: Kluge 2011: 362

Type species: Cloeon simile Eaton 1870 .

Diagnosis. Larva. In contrast to Cloeon, additional dorsal lamella of tergalii without anterior-proximal projection; dorsal lamella may be absent on tergalii of some posterior pairs. Labial palp with 3rd segment (truncate) either widened, or non-widened. Cerci and paracercus with long bare last segments (as in Cloeon, in contrast to Pseudocentroptilum and Procloeon). In contrast to Procloeon, distal part of cercus without one large spine on each segment (Kluge & Novikova 1992: Fig. 5: 10–13).

Winged stages. In contrast to Cloeon, unpaired sclerotized projection of penial bridge semicircular or truncate; fore wing of female not colored. Known species without hind wings. Oviparous.

Distribution. For certain known from Palaearctic Region.

Composition. Similicloeon petropolitanum (Kluge & Novikova 1992 [ Cloeon (Intercloeon)]) comb. n., Similicloeon praetextum (Bengtsson 1914 [ Cloeon]) comb. n., Similicloeon schoenemundi (Bengtsson 1936 [ Cloeon]) comb. n., Similicloeon simile (Eaton 1870 [ Cloeon]) comb. n., Similicloeon spiniventre (Kluge & Novikova 1992 [ Cloeon (Intercloeon)]) comb. n.

Discussion. Originally, Intercloeon was separated from Similicloeon by widened labial palp, which was regarded to be a synapomorphy of Intercloeon and Procloeon (Kluge & Novikova 1992) . Actually, this character repeatedly appears among Cloeonini, that is proven by the fact that both widened and non-widened labial palps are found among species of the holophyletic taxon Cloeon s.str.
