Shell. Dextral, elongated-ovate, of 5½ to 6½ whorls slightly convex ( Figure 9A – C View Figure 9 ). Shell whitish to yellowish brown. Protoconch with thick, axial, elevated costules slightly wavy, discontinuous, and parallel to each other ( Figure 10A – C View Figure 10 ). Costules separated by regular narrow spaces ( Figure 10A – C View Figure 10 ). Spiral grooves thinner than costules, parallel, more densely arranged, crossing them ( Figure 10A – C View Figure 10 ). Spire high conic, with whorls increasing regularly in diameter ( Figure 9A – C View Figure 9 ). Body whorl tall in relation to the total height of the shell, 75% of the total length ( Figure 9A – C View Figure 9 ). Teleoconch with axial, elevated oblique ribs ( Figure 9A – C View Figure 9 ), irregularly arranged. Suture simple, deep ( Figure 9A – C View Figure 9 ). Aperture elongated-ovate, tall, half the total shell length ( Figure 9A – C View Figure 9 ). Parietal space narrow, smooth ( Figure 9A – C View Figure 9 ). Peristome simple not expanded ( Figure 9A – C View Figure 9 ). Umbilicus rimate ( Figure 9A – C View Figure 9 ).

Measurements. Type material measurements in Table 1 View Table 1 .

Range of variability of the species: masd = 8.93 – 11.98; misd = 8.70 – 11.0; th = 18.80 – 29.87; bwh = 14.70 – 22.11; sh = 5.60 – 8.90; ah = 10.0 – 15.35; mad = 6.10 – 8.90.

External morphology. Animal body homogeneously pale yellowish, with lateral groove from genital orifice towards mantle collar, well marked. Foot elongate, basal sole homogeneous, not divided.

Digestive system. Jaw arched with nine to 11 plaques, without sculpture. Central plaque triangular not divided. Lateral plaques rectangular in shape, the two next to central plaque similar in size, following lateral plaques smaller than the central plaque. Central tooth small, triangular, tricuspid, with rounded tip ( Figure 11A, B View Figure 11 ). First lateral tooth tricuspid, similar in size and shape to central tooth ( Figure 11A View Figure 11 ). Following lateral teeth bicuspid, ectocones developed ( Figure 11C View Figure 11 ). Tooth lateral from 23 teeth of the tooth central bicuspid with serrate ectocone (splitting into two little cones) ( Figure 11C View Figure 11 ). Marginal teeth bicuspid with a rounded ectocone ( Figure 11D View Figure 11 ).

Pallial system (10 specimens dissected). Secondary ureter opening at half rectum length. Rest of system idem to B. rudisculptus .

Reproductive system (10 specimens dissected). Free oviduct longer and thinner than vagina ( Figure 12A View Figure 12 ). Bursa copulatrix duct long reaching middle portion of albumen gland ( Figure 12A View Figure 12 ). Bursa copulatrix duct with inner zigzag longitudinal folds. Vagina cylindrical, 1/3 of penis length ( Figure 12A View Figure 12 ), inner wall with straight longitudinal parallel folds. Epiphallus the same length as the penis ( Figure 12A, B View Figure 12 ). Proximal penis swollen, with inner zigzag folds followed by smooth area, distal portion cylindrical with inner zigzag folds ( Figure 12B View Figure 12 ). Rest of reproductive system idem to B. rudisculptus .

Remarks

Bostryx tortoranus was originally described by Doering (1879) in Bulimulus (Bulimulus) Leach, 1815 , based on shell and jaw characters. Subsequently Pilsbry (1895 – 1896) classified it in Bulimulus (Bostryx-Lissoacme) Pilsbry, 1896 due to the absence of sculpture on the protoconch. Later, Parodiz (1946) confirmed that the protoconch of this species had a spiral striation and classified it as B. tortoranus in Peronaeus Albers, 1850 . Finally, Breure (1979) relocated B. tortoranus to Bostryx , a placement currently maintained ( Miquel 1995; Cuezzo et al. 2013).

The examination of the type material and numerous other specimens in the Argentinean museums indicates that this species shows high shell variability in form, size and coloration. In agreement with Miquel (1995) and Cuezzo et al. (2013), Bulimulus jujuyensis , Bulimulus hyltonscottae and Bulimulus gladysae are also considered here as synonyms of B. tortoranus .

Distribution and habitat

Bostryx tortoranus is found latitudinally from Jujuy to San Luis provinces (23 – 32° S) and longitudinally from Jujuy to Catamarca (65 – 67° W). A distributional break between 27° and 31°S in the distribution of B. tortoranus has been registered. This species inhabits a variety of xerophilic environments of High Monte, Dry   GoogleMaps Chaco and Central Andean Puna   GoogleMaps ecoregions ( Figure 4 View Figure 4 ). It   GoogleMaps is common at altitudes from 944 to 3200 m, with the lowest locality corresponding to Pocho Department in Cordoba Province (Dry Chaco) and the highest locality including Cachi Department in Salta Province (High Monte). It is usually found inside crevices between rocks or on the vegetation.
