Type locality. Porzteich ( Czech Republic), Vienna Basin .
Type stratum. Baden Formation.
Age. Middle Miocene, middle Badenian (Langhian).
Etymology. hoplites, Ancient Greek for hoplite, an armored soldier, as noun in apposition.
Diagnosis. Small, stocky biconic shell with keeled periphery, indistinct suture, weak axial sculpture overrun by prominent, scabrose subequal primary cords (P1 to MP). P1 placed above anterior suture.
Description. Small, stocky biconic shell; apical angle 61°. Protoconch high conical of about three convex whorls with two spiral cords below mid-whorl. Teleoconch of up to four whorls. Suture indistinct, linear. First teleoconch whorl weakly convex with indistinct axial ribs overrun by two prominent, rounded, scabrose primary cords (IP and P1); subsutural ramp of second and third whorls nearly straight sided, lacking axial ribs, with three close-set cords (adis, IP, abis). Last whorl attaining 80% of total height, with broad, weakly convex subsutural ramp, keeled periphery, conical below. About ten indistinct axial ribs mainly developed along shoulder and slightly below. Subsutural ramp with prominent adis, IP, abis and five adapical threads; P1 very prominent, broad, strongly scabrose; P2–P6, ADP, MP of subequal strength, scabrose, slightly irregular, separated by narrow interspaces; weak secondary cords s4, s5, s6, ads. Fasciole weakly swollen; no pseudoumbilicus. Aperture ovate; outer lip weakly crenulate with weak incisions at P1 and P2. Anal canal indistinct; siphonal canal moderately long, open, wide, bent to the left. Columella broadly excavated, smooth, slightly angled at siphonal canal. Columellar callus forming broad, thin, adherent rim.
Discussion. The Paratethyan Coralliophila biconica Boettger, 1906 is reminiscent of Coralliophila hoplites sp. nov. in sculpture and general shape but is slenderer and differs in its incised suture with P1 forming the periphery of the spire whorls, the higher and narrower base and the longer siphonal canal. In addition, s2 and s3 are present whilst C. hoplites lacks these cords. Three species occur in the Mediterranean Pliocene, which are morphologically close to C. hoplites . Coralliophila turbiniformis ( Mayer, 1874) differs in its much larger size, high, scalate spire and prominent axial ribs (see Mayer 1874: pl. 11, fig. 10) and P2 can be more prominent (see Landau et al. 2007: pl. 15, fig. 7). Coralliophila miopercarinatus ( Sacco, 1904) differs in its higher spire, incised suture and differentiated primary and secondary cords and Coralliophila bononiensis ( Foresti, 1882) differs in its even broader shell, deeper pseudoumbilicus and differentiated primary and secondary cords (see Foresti 1882: 409: pl. 1, figs. 2–3). These three species have been synonymized as C. turbiniformis by Brunetti (2004), but we tentatively treat these taxa as separate species.
Paleoenvironment. Unknown.
Distribution in Central Paratethys. Badenian (Middle Miocene): Vienna Basin: Porzteich at Břeclav ( Czech Republic) (hoc opus).
