Ovary starts 1–1.5 whorls below apex, comprises about 0.5 whorls and overlaps proximal stomach chamber; renal oviduct simple, first coiling 180° clockwise, then 270° counter-clockwise; no receptaculum seminis; bursa copulatrix broadly pear-shaped, behind albumen gland, bursal duct entering subcentrally; albumen gland with opaque-white anterior and milky-white posterior section, anterior capsule gland white, posterior one yellowish.</p> <p>MALE GENITALIA (N = 2; Fig. 8A–B).

All three are morphologically very different from S. wilsoni sp. nov., though. Sulawesidrobia crutzeni is much larger and has a conical shell (see below) while S. megalodon is trochiform (Zielske et al. 2011), and S. bulat globular (Haase &amp; Bouchet 2006). In addition, S. crutzeni lacks a bursa copulatrix. In the phylogenetic trees (Figs 9–10, Supp. file 1), S. wilsoni received high support although there were only two diagnostic alignment positions, one of type 1 and one of type 3 (Table 3).</p> </div>	https://treatment.plazi.org/id/AC6487ADFFDBFF917D3523EC4612A792	Public Domain	No known copyright restrictions apply.

Short-conical, sutures very shallow, about 1.6 times as high as wide, shell and priostracum light brown; protoconch structure not verified, ca 0.8 whorls; entire shell with 3.500 to 4.250 whorls, teleoconch without structure apart from growth lines; umbilicus a narrow slit; aperture orthocline, only slightly higher than wide.</p> <p>OPERCULUM. Light yellow and thin, paucispiral, nucleus eccentric.</p> <p>EXTERNAL FEATURES. Epidermis entirely black except mantle edge, eventually pigment less dense over distal genital glands; tentacles with small, central field of cilia (Fig. 5D).</p> <p>MANTLE CAVITY (N = 4 from each locality). 16–18 (type locality) and 14–17 (2 nd locality) ctenidial filaments, respectively; osphradium ovate-elongate, underneath middle or slightly behind middle of gill, half to two thirds of length of gill.</p> <p>DIGESTIVE SYSTEM. The radula has the formula R 3-4 1 3-4/3-4 3-4, L 2 1 2-3, M1 15-20, M2 23-28, central denticle of lateral tooth with rounded tip (Fig. 6G–H); stomach without caecum, without pigment at type locality, pigmented at locality 2; intestine follows pallial genital glands, in females closer than in males.</p> <p>FEMALE GENITALIA (N = 2 from each locality; Fig. 14I–J). Ovary starts ca 1.25 or slightly more whorls below apex, comprises ca 0.5 whorls, covers stomach chambers; renal oviduct first coiling 180° clockwise, then 270° counter-clockwise; no receptaculum seminis; bursa copulatrix more or less globular, bursal duct enters anteriorly; albumen gland with opaque-white anterior and milky-white posterior section, capsule gland with small opaque white and large yellow posterior portion.</p> <p>MALE GENITALIA (N = 2 from each locality; Fig. 8H). Testis lobate, starts 0.75 (type locality) to 1 whorl (locality 2) below apex, comprises ca 1.25 whorls, covers stomach; vesicula seminalis coils along distal half to 0.75 whorls of testis; vasa deferentia insert close to middle of kidney-shaped prostate, which is much longer (almost twice as long) in locality 2 than at type locality; penis tapering continuously from broadened base, with triangular lobe in about middle on right side, can be considerable longer than in Fig. 8H, distal end subterminally grey.</p> <p>Remarks</p> <p>In the phylogenetic trees, S. dinersteini sp. nov. received high support. Its penis is unique as it is considerably shorter than the similar one of S. megalodon (see Zielske et al. 2011). Some similarity of the radula with that of S. ehrlichi sp. nov. has already been mentioned above. Sulawesidrobia dinersteini had the highest number of diagnostic alignment positions (Table 3) among the new species which clearly reflects the well-supported position in the phylogenetic analyses (see below, Figs 9–10, Supp, file 1).</p> </div>	https://treatment.plazi.org/id/AC6487ADFFCEFF847D20276B4641A34C	Public Domain	No known copyright restrictions apply.
