A broken shell of a ?Radiodiscus species is described from the Un poco del Chocó nature reserve (Pichincha province, Ecuador). This is the first time a species of Charopidae from Ecuador is described and imaged, but as small taxa have not received a lot of attention in previous studies more species are expected to be found in the country.

... The split at species level is high and most species are distinguished by very weak characters, scored by qualitative analysis (no quantitative studies on intraspecific/interspecific variability are reported). Acicula includes 26 extant (seven with fossil record) and nine fossil species ranging from Oligocene to Pliocene Bodon, 1994;Stworzewicz & Soltys, 1996;Bertrand, 2004;Kadolsky, 2008;Subai, 2009); Menkia includes three extant species and one from the Pliocene of Celleneuve ; Platyla includes 30 extant (four with fossil record) and six fossil species ranging from Eocene to Pliocene Ambrosetti et al., 1995;Cianfanelli et al., 2000;Ciangherotti et al., 2007;Bodon & Cianfanelli, 2008;Subai, 2009;Torres Alba, 2012); Renea includes eleven extant (one with fossil record) and four fossil species ranging from Oligocene to Pliocene Stworzewicz & Soltys, 1996;Ciangherotti & Esu, 2005;Niero et al., 2012). ...
Five species of aciculids are reported herein from the Zanclean (early Pliocene) of Balze di Caspreno (Tuscany, central
Italy): one belongs to the genus Acicula Hartmann, 1821, three to Platyla Moquin-Tandon, 1856 and one to Renea Nevill, 1880. Statistical
analysis (PCA and RDA) was performed on ten shell variables to test the taxonomic assignment of four of the taxa, in order to compare them
with relevant recent species. Caspreno Acicula differs from similar taxa by virtue of its more evident external peristomal varix, smaller size
and lower H/D ratio; RDA confirmed its distinction from other congeners: it is therefore assigned to a new species: Acicula kadolskyi n.
sp. The largest taxon, Caspreno Platyla, represented by only a few very fragmentary shells, is tentatively assigned to P. dupuyi (Paladilhe,
1868) by virtue of shell size and shape and structure of the external peristomal varix. The other two taxa of Caspreno Platyla are assigned
to P. gracilis (Clessin, 1877) and P. similis (Reinhardt, 1880); RDA confirmed that no significant statistical difference exists between recent
and fossil populations of the two species. Caspreno Renea, represented by only very fragmentary shells, is tentatively identified as R. veneta
(Pirona, 1865) due to its conical shape and dense ribbing. This conclusion is not supported by RDA, possibly due to the fragmentary state of
the material which made it impossible to measure some important shell variables. Apart from A. kadolskyi n. sp., the other species are still
extant. Two of these (P. gracilis and R. cf. veneta) are reported for the first time as fossils and the other two (P. cf. dupuyi and P. similis) for
the first time from the Pliocene of central Italy, although one of them (P. cf. dupuyi) had previously been recorded from the Fossil Forest of
Dunarobba, based on misidentified material of P. similis.
A new species of the genus Platyla is described, which was found in a cave in Cantabria (N Spain). It has important differences compared to other species of the genus described in Spain, particularly regarding measurements.
