Fig. 5
Baetis flaveola F.-J. Pictet, 1843 -1845: 186-187, pl. 23, fig. 4.
Heptagenia flaveola. – Eaton, 1871: 136 (transfer).
Ecdyurus verticis (Say, 1839). – Eaton, 1888: 256 (synonymy).
Heptagenia interpunctata (Say, 1839). – Ulmer, 1921: 242 (synonymization).
Stenonema flaveolum. – McCafferty & Bae, 1992: 169 (transfer and considered a nomen dubium).
Accepted name: Baetis flaveola F.-J. Pictet, 1843 nom. dub.
Locus typicus: “… Amérique septentrionale…”.
Remarks: F.-J. Pictet (1843: 187) mentioned only one female specimen from the NMW sent by Kollar (“L’exemplaire qui a servi a cette description... “), and provided only one illustration (F.-J. Pictet, 1843: pl. 23, fig. 4). There is a heavily damaged specimen in the NMW, which corresponds well with Pictet’s written description (but not with the illustration in fig. 4). As already pointed out by Ulmer (1921), another specimen has obviously been illustrated on plate 23, fig. 4 of the original publication.
Type material: NMW; ♀ subimago [syntype?] (Fig. 5A); Pöp[pig] 852 / Pictet vidit / Baetis flaveola Pict. [Hermann Hagen’s handwriting] / Heptagenia interpunctata Say [Ulmer’s handwriting] / coll. Nat. Mus. Wien / (Fig. 5B). Heavily damaged (head, left wings, left middle leg, right middle and hind leg missing, right wings partly missing and glued to thorax, end of abdomen damaged and cerci missing). – NMW; ♂ subimago [syntype?] (Fig. 5C); Par[reyss]. c. 17. 196. / Pictet vidit / Heptagenia pulchella Walsh (?) [Ulmer’s handwriting] / coll.Nat.Mus.Wien (Fig. 5D). Slightly damaged (left fore leg, basal half of left hind wing and right hind wing completely missing, distal part of cerci missing).
Remarks: Eduard Friedrich Poeppig (1797-1868) travelled in Cuba (1823-24) and Pennsylvania (1824- 26). In 1826 he departed for Valparaiso and spent several years performing scientific explorations throughout Chile, Peru and Brazil during 1827-1832. Material from his travels was acquired by the NMW in 1840. In later years he also sold specimens from different sources (Cuba 1843, Port Natal 1845, etc.). Ludwig Parreyss (1796-1879) was an established natural history dealer (mostly in insects and birds) in Vienna and material has been very frequently acquired from him by the NMW.
McCafferty & Bae (1992: 70) in their discussion confused part of the labels and erroneously reported Hagen’s label as being with the male subimago. None of the specimens, however, can be identified with any degree of certainty and McCafferty & Bae’s decision to consider the name Baetis flaveola F.-J. Pictet, 1843 as a nomen dubium should be followed.
