Box 9517, NL 2300 RA Leiden, The Netherlands; [email protected] The diagnosable,geographically localized forms ofCarinigera buresi that are known from NE Greece, are dealt with systematically as subspecies. Two subspecies are described as new to science, viz. C. b. nordsiecki and C. b. polimilitis. The structure of the lamellainserta, hitherto neglected in this species, turned out to be partially diagnostic. words: Key Gastropoda, Pulmonata, Clausiliidae, Carinigera, clausilial apparatus, lamella inserta taxonomy, Greece. INTRODUCTION During malacological fieldwork in NE Greece, the authors, searching for clausiliids in particular, came across some geographically localized forms of Carinigera buresi (A.J. Wagner, 1927). Nearly all these vicariant forms are mentioned already in the literature but of them still have valid (Nordsieck, 1977), some no names. They proved to be more differentiated be clearly than could concluded from the published data. Here we cha- illustrate and these of which racterize, name taxa as subspecies, two as new to science. Greece Only the taxa represented in are included. The only subspecies reported from outside Greece, i.e. C. b. damjanovi Likharev, 1972,from adjoining Bulgaria, couldnot be dealt with in a comparable way because oflack of sufficient research material. Carinigera buresi can be recognized by its medium-sized (height 10.4-19.3 mm), dark- to with less white sutural line greyish-brown shell, a more or prominent, narrow, and some white sutural papillae onthe initial teleoconchwhorls. The lunellais situated dorsally. The initialwhorls are convex, the lower ones are increasingly more flattened.Both the lamel- la and the suturalis less discernible fine parallela plica are usually more or clearly as very lines. Their structure is not clearly diagnostic for any of the subspecies. The same applies to the presence versus absence ofboth a fold and a whitish, oblique, more or less broaden- ed below the patch plica principalis in the aperture. In all but one subspecies at least the middle whorls are smooth; rather coarse radial riblets be on the initial tele- may present oconch whorls and on the final half to quarter of the body whorl. The apertural hp is reflected and be may strongly to extremely thickened, characterizing an entire popula- individual tion, or as only an character. The shell measurements (based on over 50 speci- for all with between the sub- mens subspecies) may vary considerably, large overlaps even species that differ most for this character, i.e. C. b. dramaensis with a shell height varying between and and C. b. conciliatrix 10.4 16.5 mm measuring between 14.2 and 19.3 mm. To differentiatebetween the subspecies the following conchological characters are con- sidered useful: the ofthe the most (1) shape aperture, (2) position and prominence of a dorsal crest on the body whorl, (3) the sculpture of the middle whorls, (4) the shape of the lamellacolumellaris, (5) the forward extension ofthe lamella subcolumellaris, (6) the lamella inserta and its relation to the spiralis, (7) the plica principalis and its relation to the lunella, the and ofthe basalis.

It is a short lamella (figs 1-2), that may be present, running obliquely between the ends of the lamellae columellaris and It the distal inner spiralis. supports most part of the clausilialstalk, where the clausilial blade begins. Whenever developed, the lamel- hole that shouldbe made the wall ofthe la inserta is visible only through a in body whorl, behind the lunella. In C. the inserta is either lamella buresi, developed as a separate (fig. 1), or it is more or less smoothly connected to the spiralis (fig. 2). In the latter case, the its it lamella spiralis may seem to have an irregular course near innerend, where smooth- less after ly changes into the inserta. It may also continue regularly, but more or obsolete, the inserta. The lamellainserta described Schmidt only contacting was clearly already by (1868: 6-7), who indicated that its character states cansometimes be used to characterize low level taxa.
