59078785FFABFFE60DDCF9CCFE17F844.taxon	description	SEM (Figs 12 – 20): — Externally, striae composed of elongated chamber-like areolae and covered by vela (Figs 12 – 16). Raphe straight and filiform. Proximal raphe ends expanded and unilaterally deflected (Figs 12, 14). Terminal raphe curved to hook-shaped and continuing onto the mantle (Figs 12, 13, 16). Axial area narrow, rhombic. Fascias present, forming rhombic central areas (Fig. 12). Internally, areolae openings interrupted by siliceous bridge that divides striae in two parts (Fig. 17), one small, rounded and located on the valve face-mantle junction, whereas the other elongated and located on the valve face. Proximal raphe ends unilaterally hooked (Fig. 19). Terminal raphe ends weakly deflected and terminated as well-developed helictoglossae (Figs 18, 20).	en	Cui, Nini, Liu, Qi, Liu, Xudong, Nan, Fangru, Kociolek, John Patrick, Xie, Shulian (2023): Chamaepinnularia taihangensis sp. nov.
