Nine apertural dentitions, reaching peristome edge: three on parietal wall, palatal tubercle, four on palatal wall, and two on columellar wall. Palatal tubercle continuous with upper palatal plica.</p><p>Description.</p><p>Shell concave-conical, colourless; spire high and growing regularly; last whorl expanded. Shell height 2.1–2.3 mm and shell width 1.8–1.9 mm. Apex blunt; protoconch ~ 2 whorls with fine spiral striae. Whorls 4–5, rounded and convex; suture wide and well impressed. Shell surface sculptured with equidistantly spaced spiral striae, crossed with irregular radial growth lines making a rectangular reticulated sculpture throughout shell. Penultimate whorl regularly coiled; last whorl bluntly shouldered and flattened below periphery. Aperture subovate; peristome thickened and slightly expanded. Aperture with nine or ten dentitions and with more or less strong knobs reaching peristome edge. Parietal wall with three lamellae: parietal lamella large, strongly developed, and high and long deeper inside aperture; infraparietal lamella long and low; angular lamella relatively smaller than parietal lamella, long, low near peristome edge, somewhat sinuous, and higher deeper inside aperture. Palatal tubercle strongly developed with triangular shape and continuous with upper palatal plica. Palatal wall with four plicae: upper-, inter-, lower-, and infra-palatal plicae connecting with peristome in the form of prominent tubercles then continuing as narrow and low, becoming strong and high inside aperture. Inter- and lower-palatal plicae much larger than upper palatal plica, infrapalatal plica smallest or may be absent (Fig. 15 A). Basal plica may be present with small and low ridge. Columellar wall with two lamellae: columellar lamella strong and distinct, continuing deep inside aperture; subcolumellar lamella small, low. Umbilicus widely perforate, ~ ⅓ of shell width, rounded and deep.</p><p>Differential diagnosis.</p><p>This new species can be distinguished from A. cryptidentatus from northern Thailand by having major dentitions (on parietal, palatal, and columellar walls) that become strong knobs when reaching peristome edge, palatal tubercle continuous with upper palatal plica, and without tiny plicae inside the sinulus. In comparison, A. cryptidentatus possesses dentitions that do not reach the peristome edge, a palatal tubercle situated between upper- and inter-palatal plicae, and with two tiny plicae inside the sinulus.</p><p>Acinolaemus corusticorus sp. nov. is similar to A. dayanum (Stoliczka, 1871) from Myanmar and A. mueangonensis from northern Thailand in shell form and sculpture. It differs by having a colourless shell without cervical crest (a swelling or convex ridge on the last whorl behind the expanded lip); parietal lamella has a thick and high ridge; angular lamella has a continuously high ridge and without incision; palatal plicae short (&lt;½ of last whorl length when seen from lateral view; Fig. 13 D, E), palatal plicae continue from knobs on peristome edge with short, narrow, and low ridges, and then becoming high inside the aperture. For comparison, A. dayanum and A. mueangonensis have palatal plicae continuing from peristome knobs, which are long and narrow but low ridges before becoming folds inside aperture. Acinolaemus mueangonensis possesses a brownish and conical to elevated conical shell; parietal lamella has a low ridge near the peristome then becoming a tall ridge inside; angular lamella has a high ridge with narrow and low ridge in middle; palatal plicae long (&gt; ½ of last whorl length when seen from lateral view; Fig. 13 B, C). Acinolaemus dayanum has a conical low spire with a cervical crest (a swelling or convex ridge on the last whorl behind the expanded lip); parietal lamella has a low ridge near peristome edge then gradually becoming a tall ridge inside; angular lamella has a high ridge near peristome edge and then gradually becoming a low ridge inside aperture.</p><p>Acinolaemus ptychochilus from northern Thailand also clearly differs from A. corusticorus sp. nov. in shape of parietal and angular lamellae, and in having four palatal plicae (upper-, inter-, hooked lower-, and infra-), a small basal plica, and three columellar lamellae; palatal tubercle situated between upper- and inter- palatal plicae. Acinolaemus rhamphodon Thompson &amp; Upatham, 1997 and A. stenopus Thompson &amp; Upatham, 1997 differ from A. corusticorus sp. nov. in having fewer dentitions, a very strong angular lamella, and a weak parietal lamella. Both species also possess two palatal plicae (upper- and lower-), and a columellar lamella. Finally, A. rhamphodon has a hooked columellar lamella, while A. stenopus has an elevated shell with a high spire, and an enlarged angular lamella and palatal plica that nearly enclose the sinulus.</p><p>Distribution.</p><p>Acinolaemus corusticorus sp. nov. is known only from the type locality. At this locality, the species is sympatric with five other hypselostomatid species: Hypselostoma pendulum (Panha &amp; Burch, 2002), H. khaowongensis Panha, 1998, A. mueangonensis, A. rhamphodontis sp. nov., and Krobylos takensis Panha &amp; Burch, 2004 (Panha 1998 b; Panha et al 2004).</p><p>Etymology.</p><p>The specific name corusticorus is from two Latin words co- meaning ‘ together or with’ and rusticor meaning ‘ living in the country’, referring to the new species being sympatric with two other congeners.</p><p>Remarks.</p><p>Although this new species occurs sympatrically with A. mueangonensis, under the microscope it is evident that they are two distinct species. Acinolaemus corusticorus sp. nov. differs from sympatric congeners by having a colourless, short, and stout shell (Fig. 13 A), while A. mueangonensis has a much smaller and more slender shell, and with pale brownish to brownish shell colour. In addition, these two species are clearly distinct in number and morphology of apertural dentitions.</p></div>	https://treatment.plazi.org/id/B875F10AA7355F0993EA1DD2F53525CA	Public Domain	No known copyright restrictions apply.

Basal plica low and long deeper inside aperture. Columellar lamella strong, high, and continuing deep inside aperture. Umbilicus widely perforate, ~ ⅓ of shell width, rounded and deep.</p><p>Living animal.</p><p>Snails are typically stylommatophoran with two pairs of tentacles. Upper tentacles are long, stout, cylindrical tubes, dark greyish, and with dark eye spots on the tip (Fig. 12 C, D). Lower pairs are very short to knob-shaped and can be seen clearly in full extension in moving snails. Animal with short body, anterior-dorsal side with grey to blackish pigmentation, and posterior body and foot pale greyish to semi-translucent. The snails tend to cover their shell with soil, mud, or dirt.</p><p>Distribution.</p><p>Acinolaemus mueangonensis has a distribution beyond its type locality in northern Thailand (Changlom et al. 2019), since during this study several specimens were collected in soil samples taken at the base of limestone cliffs and outcrops in Tak Province, ca 170 km south of the type locality.</p><p>Remarks.</p><p>The specimens from the type locality examined herein have shell sculpture and apertural dentition similar to the original description and the type specimens (Changlom et al. 2019), except for the presence of a tiny plica in the sinulus, which was not mentioned in the original description.</p><p>The specimens from central Thailand (Tak population) show the same distinguishing characters as the type specimens: a brownish shell, rectangular reticulated sculpture, and long denticles deep inside the aperture and becoming strong knobs when reaching the peristome edge. In addition, the parietal lamella has a low ridge near the peristome that becomes a tall ridge inside the aperture, and the angular lamella has a high ridge with a narrow and low ridged incision in the middle. However, the central Thailand population (Fig. 12 A, B) differed from typical specimens (Fig. 11 A, B) in having a more concave-sided shell, a more elevated and slender spire (height 2.1–2.2 mm and width 1.7–1.8 mm), and the penultimate whorl slightly sunken into the last whorl. Additionally, the central Thailand population has a basal plica instead of a subcolumellar lamella, while a typical shell has a subcolumellar lamella instead of a basal plica. However, the distinction between the subcolumellar lamella and the basal plica is sometimes difficult and not a reliable character for species distinction and is subject to intraspecific variability. Therefore, we provisionally recognise the central population as conspecific with A. mueangonensis, since no concrete difference in morphology could be observed. DNA sequence data are needed to resolve this ambiguity.</p></div>	https://treatment.plazi.org/id/6482881F8AD25706BCF8AA1AB433E805	Public Domain	No known copyright restrictions apply.

Upper tentacles are long, stout, cylindrical tubes, colourless to translucent, with dark eye spots on the tip. Lower pairs are very short to knob-shaped (difficult to observe in living snails). Animal with short body, anterior-dorsal side brownish while posterior body and foot paler to translucent. The snails tend to cover their shell with soil, mud, or dirt (Fig. 17 D – F).</p><p>Distribution.</p><p>This new species is known only from the type locality, where the empty shells and one living snail were found in the soil, leaves, and twig litter at the base of a limestone cliff. The type locality is an island located in the reservoir of Bhumibol Dam, ca 45 km northwest of Tak Town. This island is ca 400 m long and 200 m wide and aligned north-south; the dry shells and the specimen were collected from the eastern slope of the island. The hills are low, with scattered land used by temples and with some exposed limestone rocks and cliffs. The vegetation on this island is dominated by low, dry, dipterocarp forest.</p><p>Differential diagnosis.</p><p>The shell of A. rhamphodontis sp. nov. is most similar to A. dayanum from Myanmar, and A. cryptidentatus, A. mueangonensis and A. ptychochilus from Thailand. They all share a rectangular reticulated shell sculpture, many long dentitions that reach the peristome edge where they form small denticles (except in A. cryptidentatus) and have a palatal tubercle (Thompson and Upatham 1997; Changlom et al. 2019; Tongkerd et al. 2024). The differences are that A. rhamphodontis sp. nov. has a long and descending tuba and a spire sunken into the last whorl. In contrast, the other four species have no tuba, and have a conical spire with straight to curved sides.</p><p>Acinolaemus rhamphodontis sp. nov. differs from A. carcharodon Vermeulen et al., 2007 and A. pyramidalis (Vermeulen et al., 2007) from the Mekong Delta limestone hills in Vietnam, and A. rectus Vermeulen et al., 2019 from Cambodia in having a long and descending tuba, long dentitions that reach the peristome edge, and a rectangular reticulated shell surface. In comparison, these three species possess a very short tuba, prominent radial ridges, and dentitions that are short and situated inside to deep inside the aperture. Additionally, A. carcharodon has a sunken spire and four dentitions (parietal, hooked angular, palatal, and basal), A. pyramidalis has a conical spire and four to five dentitions (parietal, angular, two palatals, and a very inconspicuous columellar), and A. rectus has a conical spire, last whorl rounded, tuba slightly ascending and five dentitions (parietal, angular, two palatals, and columellar) (Vermeulen et al. 2007, 2019).</p><p>This new species has a long descending tuba similar to several species in the Clostophis sankeyi species group. It differs by having rectangular reticulated shell sculpture, with eight apertural dentitions (parietal, infra parietal, angular, two palatals, basal, and two columellar) reaching the peristome edge, and with a palatal tubercle present. Furthermore, A. rhamphodontis sp. nov. has 14–16 dash-like spiral striae on the last whorl and the penultimate whorl not sunken, whereas C. sankeyi, C. proboscideus, C. yoga, and C. udayaditinus have 18–20 or more continuous spiral striae on the last whorl, and the penultimate whorl sunken into the last whorl. Clostophis yoga also has a narrower umbilicus, &lt;1 / 3 of the shell width, than the new species (Benson 1860; Páll-Gergely et al. 2020; Páll-Gergely and Hunyadi 2022; Sutcharit et al. 2025). Finally, A. rhamphodontis sp. nov. also differs from C. rhynchotes sp. nov. by having a rectangular reticulated shell surface and dash-like spiral striae on the last whorl, while C. rhynchotes sp. nov. has a weak reticulated shell surface and continuous spiral striae on the last whorl.</p><p>Etymology.</p><p>The specific name rhamphodontis is from two Greek words: rhamphos meaning ‘ curving beak’ and odontos meaning ‘ tooth’. Together they refer to the tuba that curves downward and the many dentitions in the aperture.</p><p>Remarks.</p><p>The presence of a rectangular reticulated shell sculpture and the many dentitions reaching the peristome edge where they form small denticles and extend inside the aperture, clearly position A. rhamphodontis sp. nov. within the genus Acinolaemus (Thompson and Upatham 1997) .</p></div>	https://treatment.plazi.org/id/93B43A14CFBA50E4B61CF690F5141DB2	Public Domain	No known copyright restrictions apply.

(2020) and Páll-Gergely and Hunyadi (2022), who recorded two species from southeastern Myanmar, six species from Laos, six species from Vietnam, two species from Peninsular Malaysia, and two species from Thailand. All these species share strong spiral ridges, usually with one or many apertural dentitions (except for four species with no dentition), and a more or less detached last whorl (tuba). Other characters, such as shell shape and tuba length, show large intraspecific variation (although they can be useful in some cases to distinguish species). Based on its wide distribution and its substantial morphological variability, the genus can be divided into three phenotypic species groups:</p><p>Clostophis sankeyi species group: with 0–4 apertural dentitions, a long (~ 1 / 4 whorl or more) and descending tuba, and a conical shell shape with strongly concave sides. This group consists of five species (including Clostophis rhynchotes sp. nov.) distributed in Myanmar, Thailand, and northern Vietnam (Fig. 2 A, Table 3).</p><p>Clostophis charybdis species group: with 0–2 apertural dentitions, no to short tuba, moderately to strongly conical shell, concave sides, and aperture opened laterally to sublaterally. This species group comprises ten species, of which nine species are distributed mainly in the central to northern Annamite Ranges in Laos and central to northern Vietnam; one species is found in southern Myanmar (Fig. 2 A, Table 3).</p><p>Clostophis bactrianus species group: with four or five strong apertural dentitions, absent to short tuba, and conical to slightly concave sides. This group consists of five species with disjunct distributions. Three species from southern China tend to have long denticles deeper inside the aperture, whereas the two species from Peninsular Malaysia tend to have short denticles situated near the apertural lip (Fig. 2 A, Table 3).</p></div>	https://treatment.plazi.org/id/9BD9F1E462F757E8ADBFCA71858C7F37	Public Domain	No known copyright restrictions apply.

Umbilicus wide.</p><p>Description.</p><p>Shell concave-conical, colourless; growing regularly; last whorl slightly expanded. Shell height 1.7–1.9 mm (including tuba) and shell width 1.6–1.7 mm. Apex large and rounded; protoconch ~ 1 ½ whorls, pitted and with very narrow spiral striae. Whorls ~ 4 ½ – 5 (excluding tuba), rounded and convex; suture wide and deep. Shell surface with strong, elevated and rather equidistant spiral striae (18–22 on body whorl in frontal view), and crossed with weak to strong and irregular radial growth lines. Sometimes growth lines on earlier whorls strong, thus making reticulated surface. Penultimate whorl seemingly sunken into last whorl. Last whorl slightly shouldered to rounded; tuba long, ~ ¼ whorl, strongly descending, curving and slightly twisted. Aperture subovate, open ventrally to subventrally; peristome thin, slightly expanded and with weak depression on parietal side. Apertural dentitions two: parietal lamella relatively strong, high, and situated near apertural lip; palatal plica moderate, low, and situated slightly deeper inside aperture (infrapalatal plica occasionally present). Umbilicus widely opened, occupies ~ ½ of shell width and showing all preceding whorls.</p><p>Differential diagnosis.</p><p>Clostophis proboscideus differs from C. sankeyi and C. yoga Páll-Gergely &amp; Hunyadi, 2022 by having more numerous and more tightly coiled whorls, lower spire, and wider umbilicus. Meanwhile, C. sankeyi has weaker spiral striations, and C. yoga possesses no apertural dentition, has a narrower umbilicus (&lt;1 / 3 of shell width), and with spiral striations throughout the protoconch (Benson 1860; Páll-Gergely and Hunyadi 2022; Preece et al. 2022).</p><p>Clostophis proboscideus differs from the long and descending tuba morphs of C. multiformis Páll-Gergely &amp; Reischütz, 2020 and C. laidlawi by having a concave-conical shape, wider umbilicus, aperture opening ventrally to subventrally, spiral striations appearing at late stage of protoconch, and with two apertural dentitions (parietal and palatal). In comparison, these two latter species possess conical shells with straight sides, apertures opened sublaterally, narrow umbilicus, and with spiral striations throughout the protoconch. In addition, C. multiformis has only a parietal lamella, while C. laidlawi possesses five apertural dentitions (parietal, angular, upper palatal, lower palatal, and columellar) (Collinge 1902; van Benthem Jutting 1961; Páll-Gergely et al. 2020).</p><p>Distribution.</p><p>This species is currently known from several limestone outcrops in central Thailand.</p><p>Remarks.</p><p>The correct publication date of C. proboscideus has been specified in Jirapatrasilp et al. (2023: 24). This species was described based on three specimens: the holotype and two paratypes. The paratypes are photographed herein, one with a broken palatal wall and the other still intact (Fig. 3 A – C). However, when we revisited the type locality, we found only two empty shells (Fig. 4 A – C).</p><p>Shell variations were observed from specimens from Khao Patawi, Uthai Thani Province. These specimens possessed a general shell form similar to the type specimens but tended to have wider spaces between radial striations on the last whorl (~ 14–20), and the infrapalatal plica may be present. When an infrapalatal is present, it is located close to a larger plica, and the infrapalatal varies from a noticeable but low ridge (Fig. 5 A) to weak and inconspicuous (Fig. 5 B, C) or without an infrapalatal plica (Fig. 5 D). These variations occur syntopically, and we consider this as intrapopulation variation.</p></div>	https://treatment.plazi.org/id/523EAF63BD275CC3823F0ECAC475A586	Public Domain	No known copyright restrictions apply.
