Propyropterus

description: Propyropterus (s. str.) plateroides sp. n. (Figs. 54–55)
Description
Male. Black. Pronotum, scutellum and elytra bright red.
Head flat, with longitudinal depression behind antennal prominence. Eyes small (interocular distance about 4 times as long as the radius). Maxillary palps slender, with ultimate palpomere elongate, widened and flattened apically, about two thirds of length of palpomeres 2 and 3 combined. Ultimate labial palpomere widened apically and considerably larger than palpomeres 2 and 3. Antennae filiform, antennomeres 4–11 slightly compressed, extending to approximately three fourths the length of elytra; antennomere 3 only slightly longer and wider than antennomere 2 and both combined about 1.6 times shorter than antennomere 4; antennomeres 4–11 gradually increasing in length; antennomeres 1–3 with decumbent pubescence, antennomeres 4–11 with short erect pubescence.
Pronotum transverse, 1.1 times wider than long, trapezoidal, with pronounced, blunt anterior angles and conspicuous acute posterior angles. Median areola well­developed, rhomboidal, connected with side margins by prominent, curved carinae. Scutellum elongate, parallel­sided and deeply incised at apex.
Elytra relatively long, about 3 times longer than wide at humeri, noticeably widening posteriorly, with 4 equally developed primary costae; interstices with double rows of weak, irregular cells, with secondary costae more or less prominent and straight in basal fourth. Minute decumbent pubescence distributed along costae.
Legs slender and narrow; metatrochanters short, with rounded posterior angles; tarsomere 1 with plantar pad occupying about half of the tarsomere.
Median lobe of aedeagus narrow, slightly curved in lateral view, with a pair of minute teeth in preapical portion (Figs. 54–55).
Length: 12.9 mm. Width (humerally): 3.7 mm.
Female. Unknown.
Diagnosis
P. plateroides sp. n. differs from P. kanoi Nakane and P. pygidialis Nakane by its uniformly black underside and in the details of the structure of aedeagus (Figs. 54–55).
Etymology
The name is derived from the genus Plateros Bourgeois due to the similarity of the aedeagus of the new species to that of members the aforementioned genus.

Material studied: female, Japan, Mt. Kurodake, Kujyu, Oita Pref., 26.VI.1993, S.Ogata leg. (KMPC).
Study of Benibotarus nigripennis previously placed in Laterialis (Kazantsev, 1992), suggests that it must transferred to Greenarus as agreeing in all characters to the latter taxon. G. nigripennis has an aedeagus remarkably close to that of G. thoracicus, but it is distinguished from all congenerics, except differently coloured G. belokobylskii sp. n., which also has only one row of cells between the suture and primary costa 1, by the almost complete weakening of primary elytral costa 1, separable from secondary costae only in the basal eighth.

Material studied: Paratype male, Primorsk obl., Ulahe R., 25.V.1912, V.K.Arsenjev leg., “ Dictyoptera miranda m., Cotype, W.Barovsky det.” (Barovskij’s manujscript label) (ZIN); female, Ussurijskij Kraj, south slopes of Sikhote­Aliní, 9.V.1929, (Fillipov leg.); male and female, S Primorje (Ussuri), env.

Study of the paratype of D. miranda, as well as additional material, has confirmed the validity of the species. It is easily separable from both Laterialis oculata (Gorham) and Punicealis medvedevi Kazantsev, being most closely related to Punicealis munda (Say) from the eastern USA, from which it is distinguishable by the details of its coloration and male genitalia. The synonymy to Punicealis medvedevi (referred to as Dictyoptera oculata) was suggested by Nakane (1969) without any study of the types.

Material examined. BSPG 1952 XVIII 17 (14 spcm., 29 opercula), 44 (1 spcm.).
Description. Shell medium-sized, trochiform. Protoconch (~1½ whorl) smooth; transition to teleoconch clear.
Teleoconch sculpture reticulated, with stronger spiral ribs and weaker axial ribs; distance between spiral ribs equal to twice their width; distance between axial ribs roughly equal to their width. Whorl profile greatly convex; spire stepped. Suture deep. Aperture rounded. Umbilicus narrow. Operculum with spiral growth.
Previous identification of the material. Gall (1980: Nr. 32 and 33): respectively, Pomatias consobrinum (Sandberger) and Pomatias sp.
Discussion. The present specimens compare well with P. consobrina, being easily identified by its size and strong reticulate sculpture (Stworzewicz 1995; Kókay 2006). The species is known from the Middle Miocene (MN 5–8) of Germany, Hungary and Austria (Schlickum 1976; Kókay 2006).
Paleoecological remarks. Recent species live in forests or shrublands, with more humid soil where they can burrow (Welter-Schultes 2012).

Previous identification of the material. Gall (1980: Nr. 34): Bithynia (Bithynia) cf. glabra (Zieten). Discussion. The only fossils of this genus in the material from Gündlkofen are opercula; their overall shape and concentric growth pattern indicate the genus Bithynia, but identification at species level is impossible. Paleoecological remarks. Recent Bithynia species live in richly vegetated slow moving or standing waters, some are also found in temporary water bodies (Welter-Schultes 2012).

description: Gyraulus sp.
(Figs. 4–5)
Material examined. BSPG 1952 XVIII 16 (1 spcm.).
Description. Shell diminutive, pseudodextral, planispiral. Protoconch flattened; transition to teleoconch unclear. Teleoconch smooth, except for well-marked growth lines. Spire depressed. Suture very deep. Whorls rapidly growing. Whorl profile asymmetrical, with faint keel on lower portion of whorl. Aperture large, rounded.
Previous identification of the material. Gall (1980: Nr. 30): Gyraulus (Gyraulus) trochiformis cf. kleini (Gottschick & Wenz).
Discussion. The single specimen from Gündlkofen is a juvenile and, due to its poor preservation (lacking protoconch sculpture) and the known conchological variation in the genus (Meier-Brook 1983; Rasser 2013), classification beyond genus level is presently not possible.
Paleoecological remarks. Recent Gyraulus are found in various habitats, so their use in paleoecological analysis is limited; still, they usually thrive in richly vegetated, shallow standing or slow-flowing waters, sometimes even temporary water bodies (Welter-Schultes 2012).

description: Clausiliidae indet.
(Figs. 6–8)
Material examined. BSPG 1952 XVIII 36 (1 spcm.), 37 (6 spcm.).
Previous identification of the material. Gall (1980: Nr. 19 and 20): respectively, Pseudidyla moersingensis (Boettger) and Clausiliidae gen. et sp. indet.
Discussion. Due to the very fragmentary nature of the present specimens, a more precise identification is not feasible. Nevertheless, it should be noted that there are two distinct morphs of spire tops: one larger, with higher whorls (Fig. 6), and one smaller, with the whorls more closely packed together and growing more quickly in width (Fig. 7). There is also a single apertural fragment (Fig. 8) that was identified by Gall (1980) as Pseudidyla moersingensis (Boettger), a species known from the Middle to Late Miocene of Germany (Nordsieck 1981a, 1982). Its overall shape and dentition seem to indicate the genus Pseudidyla (Boettger 1877), but due to the fragmentary nature of the present specimens, it is impossible to safely assign them to P. moersingensis.
Moreover, Gall (1980: Nr. 18) also lists another clausiliid, Serrulina ptycholarynx (Boettger), for Gündlkofen; however, as explained above, the lot unfortunately could not be found at the BSPG collection. It should be noted, however, that Nordsieck (1981b) classified Gall’s S. ptycholarynx as a new subspecies, Serrulastra (Serruplica) ptycholarynx galli Nordsieck, and figures the holotype (pl. 8, fig. 18), which consists in a fragmentary body whorl with an intact aperture. The shell sculpture, aperture shape and dentition is congruent with the group of genera Serrulastra Nordsieck, Serrulina Mousson and Serrulella Nordsieck in Zilch. The distinction between these genera, (and their myriad of subgenera, species and subspecies) is very tenuous and classification of fragmentary fossil material is thus further complicated. As such, the validity of this subspecies should be taken carefully.
Finally, the only thing that can be safely said about the clausiliids from Gündlkofen is that they represent two species, one probably belonging to the genus Pseudidyla and the other to Serrulastra or Serrulina and likely the species S. ptycholarynx.
Paleoecological remarks. Nordsieck (2007) suggests that clausiliids up to the Middle Miocene were mostly wood-dwelling animals, preferring humid and warm environments.

Material examined. BSPG 1952 XVIII 45 (2 spcm.).
Previous identification of the material. Gall (1980: Nr. 29): Azeca cf. lubricella lubricella Boettger.
Discussion. The present specimens are simply apertural fragments, where two teeth (one columellar and one palatal) can be seen. While the aperture shape and dentition seem to clearly indicate the genus Azeca, identification beyond that remains rather tentative. Still, the dentition of the present specimens agree very well with Azeca lubricella, a species typical from the Silvana-beds in the Middle Miocene of Southern Germany (Schlickum 1976).
Paleoecological remarks. The single recent species in the genus, Azeca goodalli (Férussac), lives in leaf litter in woodlands or shrublands, often with calcareous soil (Welter-Schultes 2012). Schlickum (1976) states that A. lubricella specifically may have lived on the immediate vicinity of a water body.

Description. Shell small, depressed. Protoconch blunt, wide, smooth. Teleoconch sculptured by regularly distributed fine papillae, giving the impression of axial striae. Whorls’ profile slightly convex. Suture well-marked, deep. Whorls regularly increasing in size. Aperture crescent-shaped.
Previous identification of the material. Gall (1980: Nr. 14): Klikia (Apula) cf. coarctata coarctata (Klein).
Discussion. The single specimen from Gündlkofen, despite being slightly deformed, compares fittingly with K. coarctata, a species from the Middle Miocene of southern Germany (MN 5–6; Klein 1853; Schlickum 1976; Salvador 2013b). However, a more certain identification is not possible, since one of the main features of this species, a covered umbilicus (Klein 1853; Harzhauser & Binder 2004), cannot be observed.
Paleoecological remarks. As a fossil genus, comparison with living relatives is somewhat tentative. Nevertheless, Lueger (1981) suggested that species in this genus preferred drier environments.

Description. Shell large, 4½ to 4¾ whorls. Protoconch flattened, smooth; transition to teleoconch unclear. Teleoconch smooth, except for growth lines. Suture well-marked. Whorl profile flat on first whorls. Body whorl rounded, slightly bent downwards near aperture. Aperture prosocline, rounded. Peristome reflexed; slightly thickened on basal and columellar regions. Umbilicus imperforate.
Previous identification of the material. Gall (1980: Nr. 15): Cepaea eversa larteti (Boissy).
Discussion. The present specimens from Sandelzhausen compare reasonably well with C. eversa and can be differentiated from the specimens of C. cf. sylvestrina Schlotheim (see below) by a larger size, a higher spire, a rounder aperture and one quarter to one half additional whorl. Nevertheless, the specimens of C. eversa from Gündlkofen are always larger, also with half whorl more, than typical specimens. Nevertheless, as common in the genus, C. eversa seems to be a very variable species regarding shell morphology (Hír & Kókay 2004). It is a frequent species in Middle Miocene (MN 5–7) deposits of Central and Western Europe (Hír & Kókay 2004).
Paleoecological remarks. Recent Cepaea have too broad a range of habitats (Welter-Schultes 2012) to be useful for a paleoenvironmental analysis.

Description. Shell large, 4¼–4½ whorls, helicoid; whorls regularly growing. Protoconch flattened, smooth; transition to teleoconch unclear. Teleoconch smooth, except for growth lines. Whorl profile flat on first whorls. Suture well-marked. Body whorl slightly bent downwards. Aperture prosocline, crescent-shaped; callus faint. Peristome markedly thickened and reflexed. Umbilicus imperforate.
Previous identification of the material. Gall (1980: Nr. 16): Cepaea silvana silvana (Klein).
Discussion. The specimens from Gündlkofen compare reasonably well with C. sylvestrina, but are slightly larger, with one quarter to one half additional whorl when compared to typical C. sylvestrina; nevertheless, this species seem to be quite variable morphologically. Cepaea silvana Klein, another common species in the German Middle Miocene, is even smaller, with fewer whorls and a more rounded overall profile, and might be simply a morphological extreme of C. sylvestrina.
Paleoecological remarks. As C. cf. eversa above.

description: Limax sp.
(Fig. 21)
Material examined. BSPG 1952 XVIII 3 (15 spcm.), 39 (19 spcm), 40 (7 spcm.).
Description. Shell small, vestigial, oval; shell width ~2/3 length. Nucleus slightly bent laterally; nucleus region higher than remainder of shell. Shell with marked concentric growth lines.
Previous identification of the material. Gall (1980: Nr. 6, 7 and 8): respectively, Limax sp., Milax sp. and Parmacella sp.
Discussion. The shells of limacids are vestigial and internal and thus of very limited taxonomical value. As such, the identification of the present material cannot proceed further than genus level. The genus Limax is known in Europe from the Late Oligocene onwards (Zilch 1959–1960).
Gall (1980) identified some specimens as belonging to the genera Parmacella Cuvier and Milax Grey. The shell of Parmacella slugs are also vestigial, but exhibit a very characteristic inflated and prominent protoconch. This diagnostic feature is not present in the specimens from Gündlkofen. The shells of Milax are inflated and markedly convex, with a central elevated nucleus, features that cannot be seen in the present specimens.
Paleoecological remarks. Recent Limax species occupy a variety of habitats, but usually live in damp leaf litter (Welter-Schultes 2012).

(Fig. 22)
Material examined. BSPG 1952 XVIII 41 (3 spcm.).
Description. Shell diminutive, discoid. Protoconch (~1¼ whorl) flat, smooth; transition to teleoconch clear. Teleoconch sculptured by fine but well-marked parallel prosocline ribs; distance among ribs equal to width of rib. Whorl profile convex. Suture well-marked. Whorls regularly growing.
Previous identification of the material. Gall (1980: Nr. 9): Discus sp.
Discussion. The material is very fragmentary, but a generic assignment is possible by the distinct shell shape and sculpture pattern. Moreover, the well-marked sculpture compare well with D. pleuradrus (Bourguignat), a species widespread during the Middle and Upper Miocene of Central Europe (Böttcher et al. 2009).
Paleoecological remarks. Recent European species live in damp woodlands or grasslands (Welter-Schultes 2012).

(Fig. 23)
Material examined. BSPG 1952 VIII 46 (1 spcm.), 47 (2 spcm.).
Description. Shell small, with acuminated spire top. Protoconch (1½ whorl) narrow, rounded, smooth; transition to teleoconch unclear. Whorl profile convex. Suture deep. Teleoconch sculptured by regularly distributed, very fine prosocline ribs; distance between ribs approximately twice rib width.
Previous identification of the material. Gall (1980: Nr. 31): Cochlostoma sp.
Discussion. Only spire fragments remain and thus a more precise identification is not possible. The regular whorl growth and the fine, straight and regular ribs indicate the genus Granaria (Höltke & Rasser 2013). Moreover, the present specimens are indistinguishable from the Granaria sp. described from the Middle Miocene (MN 5) of Sandelzhausen, southeastern Germany (Salvador 2014).
Paleoecological remarks. Recent Granaria species prefer dry and open habitats, usually calcareous (Welter- Schultes 2012).

Material examined. BSPG 1952 XVIII 4 (1 spcm.).
Description. Shell diminutive, discoid, with flattened spire. Protoconch (~1¼ whorl) flat, apparently smooth; transition to teleoconch unclear. Teleoconch smooth, but with well-marked growth lines. Whorl profile convex. Suture well-marked, deep. Whorls regularly growing. Aperture round. Umbilicus wide.
Previous identification of the material. Gall (1980: Nr. 28): Helicodiscus (Hebetodiscus) subteres (Clessin).
Discussion. The present specimen compares well to L. subteres, a species known from Miocene (MN 5–6) sites of Southern Germany and Hungary (Schlickum 1976, 1979; Kókay 2006). The species of Lucilla were usually classified in the genus Helicodiscus Morse and, more specifically, in the subgenus Hebetodiscus H.B. Baker. Hebetodiscus, however, was later considered a distinct genus by Bequaert & Miller (1973), which, in turn, was then regarded as a synonym of Lucilla by Falkner et al. (2002). As such, some authors (e.g., Hubricht 1985; Hotopp et al. 2010) state that this whole Helicodiscus complex should be revised. Until then, the current approach of treating Lucilla as a distinct genus (e.g., Moser et al. 2009; Gargominy et al. 2011; Welter-Schultes 2012) is followed here.
Paleoecological remarks. The two recent European Lucilla species are subterranean (L. scintilla Lowe is even blind), living deeper in the soil than other land snails (Welter-Schultes 2012). If the extinct species shared this habit, the increased difficulty for their preservation would explain the scarce fossil record of the genus.

Material examined. BSPG 1952 XVIII 14 (3 spcm.).
Description. Shell large, fusiform; greatest width on last whorl. Teleoconch sculptured by regularly distributed, well-marked coarse ribs; distance between ribs equal to rib width. Aperture drop-shaped, vertically elongated; no apparent callus. Peristome simple, but slightly thickened on columellar region. Umbilicus imperforated.
Previous identification of the material. Gall (1980: Nr. 25): Palaeoglandina gracilis porrecta (Gobanz).
Discussion. The fragmentary and deformed preservation of the present material precludes a more precise identification. Nevertheless, the specimens are reminiscent of P. gracilis by their broad shell, strong sculpture and elongated aperture. Palaeoglandina gracilis is known from the Late Oligocene to the Middle Miocene (MN 7) of Central Europe (Salvador 2013b).
Paleoecological remarks. The genus Palaeoglandina is known since the Paleocene, being widespread throughout Europe and becoming extinct in the Early Pleistocene (Zilch 1959–1960; Esu et al. 1993). Likely, as the recent species in the family, Palaeoglandina was a malacophagous predator (Barker & Efford 2004); some authors (e.g., Moser et al. 2009) even suggested that it should have displayed the same lifestyle and habitat as the recent North American Euglandina rosea (Férussac), living on the leaf litter or on trees, with a wide habitat tolerance (Hubricht 1985; Davis et al. 2004).

Testacella (Testacella) schuetti: Schütt, 1967: 218 (fig. 19). Testacella zelli: Gall, 1980: 56.
Material examined. BSPG 1952 XVIII 22 (5 spcm.).
Description. Shell small, ear-shaped, vestigial; shell width ~3/5 shell length. Apex pointed, curved. Shell with well-marked growth lines. Aperture elongated, oval; parietal and columellar region greatly thickened.
Previous identification of the material. Gall (1980: Nr. 1): Testacella zelli Klein [sic].
Discussion. The shell is vestigial in this monotypic family and, therefore, is of very limited taxonomical value. Despite being slightly larger, the present specimens compare well with T. schuetti by its oval aperture, low shell and a pointed but curved apex. The species is known from few Middle Miocene (Sarmatian, MN 7–8) sites of the Styrian Basin and North-Alpine Foreland Basin (type locality: Hollabrunn, Austria; Schlickum 1967; Harzhauser et al. 2008). As such, the present record is the oldest for the species.
Paleoecological remarks. Recent Testacella are voracious predators, feeding on earthworms, gastropods and centipedes, and live mainly underground, thus requiring a moist soil cover (Barker & Efford 2004). This burrowing habit should make preservation in the fossil record difficult.

Type species
Thrincoceras depressum Hyatt, 1893; subsequent designation by Schmidt (1951).
Diagnosis
Genus of the family Trigonoceratidae with evolute conch; whorls slightly impressed or slightly detached; whorl profile nearly quadrate with flattened venter and narrowly rounded ventrolateral shoulder and umbilical margin. Ornament with fine growth lines and moderately coarse spiral lines. Suture line with shallow external and lateral lobes. Siphuncle small with subcentral position (after Kummel 1964; emended).
Included species
Thrincoceras depressum Hyatt, 1893, Kentucky; Gyroceras Hibernicum Foord, 1891, Ireland; Thrincoceras Hyatti Foord, 1900, Ireland; Thrincoceras kentuckiense Hyatt, 1893, Kentucky; Thrincoceras devolvere sp. nov., Algeria.
Remarks
Several genera with a coarse spiral ornament and granulation on the spirals were introduced within the family Trigonoceratidae; these show a rather continuous morphological variation:
Chouteauceras Miller & Garner, 1953 – whorls compressed, oval, separated by interspaces;
Rineceras Hyatt, 1893 – whorls depressed, oval or rounded triangular, separated by interspaces;
Pararineceras Turner, 1954 – whorls depressed, oval or rounded triangular to rounded-trapezoidal, touching or slightly embracing the preceding one;
Discitoceras Hyatt, 1884 – whorls depressed, subtrapezoidal with narrowly rounded venter, slightly embracing the preceding one;
Thrincoceras Hyatt, 1893 – whorls subquadrate in section and embracing the preceding one. However, one must bear in mind that Thrincoceras also developed an adult stage in which the whorl loses contact with the preceding one. The holotype of T. hyatti, for instance, uncoils at about 90 mm conch diameter (Foord 1900; Histon 1999).
Stratigraphic range

Remarks
Turner (1954) introduced the genus Pararineceras on the basis of the species originally described by Martin (1793, 1809) as “Conchyliolithus N. Ammonites (Luidii)”, but as Martin did not follow the Linnaean binomial procedure, Fleming (1828) is regarded as the author of the species (Turner 1953). This species differs from most of the species assigned to the genus Rineceras only by the more densely coiled conch, a character that might be gradual and not useful for a separation of genera. While Kummel (1964) accepted both of the two genera, Shimansky (1967) and Dzik (1984) regarded Pararineceras as a synonym of Rineceras. In the following, we treat Pararineceras a junior synonym of Rineceras until a clear separation can be demonstrated.
