Hallo Oliver,
ich habe noch eine Arbeit von Mottequin, 2019, gefunden. Darin wird Pholidostrophia extensa beschrieben:
"Pholidostrophia extensa Maillieux, 1938
(Figs 3M-BB, 4A-C)
1938 Pholidostrophia extensa Maillieux: 21, 36, pl. 1, figs 4-6.
1941b Pholidostrophia extensa Maillieux; Maillieux: 6.
1967 P. [Pholidostrophia] extensa Maillieux; Harper et al.: 417.
Type material. Maillieux (1938) illustrated three specimens
that he considered as the types of his new species. Nevertheless,
he did not select a holotype among them. The articulated
specimen RBINS a1119 (Maillieux, 1938, pl. 1, fig. 6), the better
preserved one in terms of ornamentation, is hereby designated
as the lectotype (Figs 3W-BB, 4A-C); the two other specimens
RBINS a1117-a1118 (Maillieux, 1938, pl. 1, figs 4, 5) are thus
paralectotypes (Fig. 3M-Q, R-V).
Type locality and horizon. Olloy 7970, Jemelle Formation
(Eifelian).
Description. See Maillieux (1938).
Remarks. Harper et al. (1967) questionably assigned this
species to Mesopholidostrophia Williams, 1950, which was
considered by these authors as a subgenus of Pholidostrophia
Hall & Clarke, 1892. Nevertheless, none of the types displays
the internal morphology that is crucial for generic identification.
On the basis of the external morphology, it is not at all excluded
that Maillieux’s species is a synonym of Pholidostrophia
(Mesopholidostrophia) semicircularis (Kayser, 1871) from the
Eifelian of the Eifel as re-illustrated by Harper et al. (1967, text-
figs 4-8).
Current name. Pholidostrophia extensa Maillieux, 1938."
Ich habe die Seite Pholidostrophia (Mesopholidostrophia) semicircularis neu angelegt.
