| Comments | Two species are described in Agardh 1832, Isthmia obliquata, Isthmia vesiculosa, and no type is designated. Farr et al. (1979) indicate that Kützing 1833 (ref. 000594), p. 579, 610, designated I. obliquata as the lectotype. Kützing 1833 treated Isthmia vesiculosa as a Biddulphia (p. 610, p. 82 in other reprint), retaining, of the original species, only I. oblicata in genus Isthmia (p. 579, p. 51 in other reprint). Kützing's action does not by itself constitute lectotypification of the genus. Boyer 1927 (ref. 000155), p. 140 gives I. obliquata as the type. |

| Comments | Two species originally included, Striatella arcuata (Lyng.) Ag., Striatella unipunctata (Lyng.) Ag., no type designated by Agardh. Farr et al. (1979) indicate that Ehrenberg 1838 (ref. 000288) designated the lectotype (p. 202, 230). Ehrenberg 1838 (p. 202) transferred Diatoma arcuatum Lyngbye (= Striatella arcuata [Lyng.] Ag.) into genus Tessella . The only one of the species originally included in genus Striatella, Fragilaria unipunctata Lyng. (= Striatella unipunctata [Lyng.] Ag.) is left by Ehrenberg in genus Striatella (p. 230) with a new name Striatella arcuata. Ehrenberg's action does not constitue lectotypification which is effected by Boyer (1927) (ref. 000155), p. 160. |
