6. Labiobaetis vinosus (Barnard, 1932)

Labiobaetis vinosus Barnard 1932

Pseudocloeon tenuicrinitum Kopelke 1980 ( Pseudocloeon tenuicrinitum ; informal synonym, Kluge 2020)

Baetis spatulatus Gillies 1994: figs 16-26 ( Baetis spatulatus ; formal synonym, Kluge and Novikova 2016)

Labiobaetis vinosus Lugo-Ortiz and McCafferty 1997: figs 75-86

Labiobaetis tenuicrinitus Kluge and Novikova 2016: figs 113, 122-129, 132, 133 ( L. tenuicrinitus ; informal synonym, Kluge 2020)

Remark.

Judging from the figures and description in Kluge and Novikova (2016), there is no morphological difference between L. vinosus and L. tenuicrinitus . Kluge (2020) also indicates the synonymy of both species. However, no formal synonymy has been established so far. As we have not seen material of L. tenuicrinitus , we are not in a position to formally synonymise both species. Further, the genetic barcode (COI) of both species remains unknown.

Differential diagnosis.

Nymph. Following combination of characters: A) colouration: abdomen dorsally brown, with pattern as Kluge and Novikova 2016: fig. 113; B) scape without distolateral process; C) labial palp segment II with broad, thumb-like protuberance; segment III conical; D) maxillary palp segment II with excavation at inner distolateral margin; E) fore femur rather broad, length ca. 3 × maximum width; dorsal margin with 8-18 curved, spine-like setae and basally a partial second row of setae; F) hind protoptera absent or minute; G) six pairs of gills.

Examined material.

Ethiopia • 6 nymphs; Lafessa ; 08°23'16"N, 38°54'31"E; 1600 m; 08.11.2017; leg. W. Graf; Lf1; 1 on slide; GBIFCH00592392 ; 5 in alcohol; GBIFCH00515562 , GBIFCH00763730 , GBIFCH00829883 , GBIFCH00829884 , GBIFCH00829885 • 4 nymphs; Korkada ; 08°30'03"N, 39°33'07"E; 1260 m; 10.11.2017; leg. W. Graf; Kk1; 3 in alcohol; GBIFCH00515561 ; 1 on slide; GBIFCH00592388 ; all material in MZL .

Biological aspects.

The specimens were collected at altitudes of 1260 m and 1600 m. Further characteristics of sampling sites are given in Englmaier et al (2020). Harrison and Hynes (1988) reported the species at 2500 m in marginal vegetation.

Distribution.

Ethiopia (Fig. 2b ), DR Congo ( Kopelke 1980), Tanzania ( Gillies 1994), Uganda ( Kluge and Novikova 2016), South Africa ( Lugo-Ortiz and McCafferty 1997).
