Rhithrogena cincta Navás, 1921 View in CoL

Rhithrogena cincta Navás, 1921: 14 View in CoL , fig. 1. – Thomas, 1968a: 212 (lectotype designation).

Material: MHNG; 1 ♂ imago; 620 Pyrénées 48 Espagne coll. Pictet / Pyrénées Juillet 1859 / 149 [handwriting] / 24 [printed] / Pot[amanthus] n. sp. / Rhithrogena aurantiaca Burm. Eaton determ. [fore legs missing, forewings damaged, genitalia rehydrated and put in microvial with glycerine].

Remarks: This specimen has certainly been collected by A.-E. Pictet on his way back to Geneva when he left San Ildefonso in mid July 1859. The identification by Eaton followed the common interpretation of Baetis aurantiaca at that time. Since then, it has been shown that Burmeister’s concept of R. aurantiaca applies to an Ecdyonurus species ( Puthz, 1973b) . Rhithrogena cincta has been redescribed by Thomas (1968a), who designated from Navás’ collection a lectotype originating from Vilallonga in the Spanish Pyrenees. The specimen collected by A.-E. Pictet completely fits the diagnosis proposed by Thomas (1968a), particularly in the shape of the styliger plate with well marked postero-lateral protuberances, in the marking of the abdomen, and in the marking of the coxae with two elongated stripes (see Thomas 1968a: pl. I, figs 2-3, pl. II, fig. 2 and Fig. 10 View Fig ). Penes lobes clearly correspond to those of the diaphana -group, but differences between R. diaphana and R. cincta are insignificant. The status of this species should be solved on the basis of new material. This specimen is only the second one known for this species.
