Properties
Habitat: benthic
Descriptio. Valvae elliptico-lanceolatae, extremitatibus late rostellatis, 33.8—35.6 µ longae, 21.5—22.7 µ latae. Valva superior area axili anguste lineari, medio striis radialibus grandibus levibus 10—11 in 10µ, extremitatibus 14—17 in 10 µ donatae. Valva interior area axili lineari, area media transversaliter dilatata, bifurcata. Striae radiales, tenere punctulatae, valvae medio 14—16, in extremitatibus 18-20 in 10 µ.
Habitatio. Mare Nigrum ad insulam Tendra 7 m alt. inter algas, Junio, raro.
Typus in diatomotheca Sectionis cryptogamicae Inst. Bot. Acad. Sci. URSS in Leningrad conservatur.
Observatio. Achnanthes lyrata ab omnibus speciebus cognitis generis valva interiore tigura lyritormi ornata dittert. Valva superior speciei fossilis periodi tertiariae e Ponto, Euxino[Ach.baldjikii (Bright.) CI.].

Hillebrand et al., 1999 - elliptic prism
(in species which are genuflexed in girdle view, the apical axis can be calculated more precisely, if the length of the two straight parts is summed; - species with a rhombic valve view should be calculated as prisms on a parallelogram; - species with a linear valve view should be calculated as boxes; - some species have great capitate poles, these can be added as cylinders. In this case, the apical axis means the apical length without the capitae) (Hillebrand, H., Dürselen, C. D., Kirschtel, D., Pollingher, D. and Zohary, T. (1999) Biovolume calculation for pelagic and benthic microalgae. J. Phycol., 35, 403–424)
