Leiogalathea

description: Genus Leiogalathea Baba, 1969
Leiogalathea Baba, 1969: 2 (gender: feminine).— Baba 2005: 88.— Baba et al. 2008: 83 (compilation).— Baba et al. 2009: 133.— Macpherson & Baba 2011: 63. Liogalathea Baba, 1990: 962 (misspelling).
Type species. Galathea imperialis Miyake & Baba, 1967, by original designation.
Diagnosis. (Modified from Baba et al. 2009; Macpherson & Baba 2011). Carapace dorsally unarmed, surface transversely convex, with few uninterrupted transverse striae and numerous short and scale-like ridges of different length, usually with numerous short setae and scattered stiff long setae, laterally with a few spines; anterior cervical groove barely discernible. Rostrum triangular, dorsally flat or concave, with 0–9 lateral teeth, usually obsolescent. Lateral limit of orbit rounded. Sternum broader than long, maximum width at sternites 6 and 7; sternite 3 relatively short, anterolaterally produced; anterior margin of sternite 4 broad, often contiguous to entire posterior margin of preceding sternite. Abdomen unarmed, smooth, with sparse long and thick uniramous setae; telson subdivision nearly complete. Ocular peduncles short relative to breadth, cornea not dilated. Antennular article 1 with strong distolateral spine, strong distodorsal spine and with or without small or minute distomesial spine. Antennal peduncle not reaching end of rostrum. Antennal article 1 armed with distomesial spine only, article 2 with distomesial and distolateral spines. Short flagellum on Mxp1. Mxp3 merus with strong median spine and with or without minute distal spine on flexor median margin, distinct spine on extensor distal margin, carpus, propodus and dactylus unarmed. P1–4 with stiff long setae. P1 spinose, triangular in cross section. P2–4 dactyli distally ending in a strong claw, with row of distinct flexor teeth. Gonopods 1 and 2 in males present.
Remarks. Baba (1969) designated Galathea imperialis Miyake & Baba, 1967 as the type species of the genus Leiogalathea, but later considered L. imperialis as a junior synonym of L. laevirostris (Balss, 1913) (Baba, 1990). Therefore, L. laevirostris has been inadvertently listed as the type species of the genus in more recent studies (e.g. Baba 2005; Baba et al. 2008; Macpherson & Baba 2011) although the type species of Leiogalathea remained Galathea imperialis. Here, we resurrected Leiogalathea imperialis from synonymy as a valid species.

Plekocheilus (Plekocheilus) fulminans linterae (Sowerby, 1890) (Figs 4 A─D, 9A)
Bulimus fulminans linterae Sowerby, 1890: 582, pl. 56 fig. 12. Type locality: British Guiana, Mount Roraima; lectotype BMNH 1889.4.25.1 (Breure 1978).
Material. Guyana, Mount Roraima (BMNH 1889.4.25.1/ lectotype, 1889.4.25.2/1 paralectotype, SMF 90007/ 1 paralectotype); Ibidem, T. Pain leg., 1938 (NMW.Z 1981.118.00303/3); Ibidem, 8000 ft [2438 m], T. Pain leg., 1938 (NMW.Z 1981.118.0 4142/1). British Guiana [= Guyana] (ex Melvill Tomlin, NMW 1955.158.16700/1; ex Preston, RMNH /1).
Remarks. The lectotype and paralectotype from the BMNH collection are figured here for the first time (Figs 4 A─D). Although we do not precisely know where the type specimens were collected, we may infer from the locality given by Sowerby that it was on the slopes or base at the northeastern side of Roraima-tepui (R.W. McDiarmid, personal communication). Nonetheless, the material collected by T. Pain reveals that this is a highland species. The material also shows that there is some variation in expression of the columellar fold (in two specimens it is hardly noticeable) and in the colour of the lip (in three specimens dark liver coloured, in two other specimens whitish like in the type material).
Plekocheilus (Plekocheilus) fulminans alticola Haas, 1955 (Figs 4 E─G, 9 B)
Plecocheilus (Plecocheilus) fulminans alticola Haas 1955: 381, fig. 81. Type locality: Venezuela, State of Bolívar, Chimantá massif, Torono tepui, on slopes bordering Caño Mojado, 2250 m; holotype FMNH 52442.
Material. Venezuela, Estado Bolívar, Chimantá massif, Toronó-tepui, slope bordering Caño Mojado, 2250 m, J.A. Steyermark leg., 21.ii.1955 (FMNH 52442/ holotype, 52443/1 paratype).
Remarks. The oblique streaks on the ventral side of the last whorl make this form resemble Plekocheilus (Eurytus) juliani Haas, 1955, but the different sculpture (malleation, Fig. 24B) and the darker colour of the peristome characterize this species. The colour pattern and the darker lip also distinguish this taxon from P. (E.) fulminans linterae.

Remarks. The intraspecific variation within the type material has been adequately described by Haas. The species is characterized by the oblique streaks and the sculpture of the shell (Haas 1955: fig. 78; Fig. 9F. A juvenile and broken specimen preserved in ethanol 70% was collected on Auyán-tepui, on the same massif as the type locality.

(Figs 4 H─L, 9I)
Eurytus fusitorsus Oberwimmer, 1931: 190, figs 1, 4. Type locality: Venezuela, Territorium Amazonas, Río Padamo; holotype SMF 5142.
Material. Venezuela, Estado Bolívar, Cerro Guaiquinima, along Río Paragua, 1500 m, J.A. Steyermark leg., 1978, in wooded portion of moist dwarf forest (FMNH 198500/1); Estado Amazonas, Río Padamo (SMF 5142/ holotype).
Shell dimensions are given Table 1.
Remarks. This species is characterized by dark, undulating stripes on the last whorl bordered by a yellowish ‘shadow’ and a fine granulation of dotted granules (Fig. 9I). A subadult specimen from Cerro Guaiquinima (FMNH 198500) is tentatively referred to this species. It is characterized by the same colour pattern as observed in the holotype, but has oblong granules on the upper part of the last whorl, giving an impression of spiral incisions in between.
The type locality is a river basin that covers 10.280 square km and drains the northwestern slopes of the Sierra Parima on the east-central border of Estado Amazonas in Venezuela and Estado Roraima in Brazil (Huber 1995a). Río Padamo is slightly east of Cerro Duida [type locality of Plekocheilus (Eurytus) tatei Haas, 1955] and Cerro Marahuaka [type locality of P. (E.) gibber (Oberwimmer, 1931)]. The headwaters of Río Padamo are on Cerro Kikirisha, slightly over 1000 m, but along its course elevations of 500 m or less prevail. Since the exact type locality is unknown, it cannot be excluded a priori that P. (E.) fusitorsus also occurs in the lowland. This species might also be expected at intermediate localities in between the two occurrences, e.g. in the Jaua-Sarisariñama massif.

Plecocheilus (Eurytus) tatei Haas, 1955: 385, fig. 84. Type locality: Venezuela, Territory of Amazon, Cerro Duida, “ledge 23B”; holotype AMNH 73455.
Material. Venezuela, Estado Amazonas, Cerro Duida, G.H.H. Tate leg. (FMNH 50346/3 paratypes).
Genitalia. Penis proximally somewhat swollen, thereafter more slender and distally subcylindrical, passing without external transition into the epiphallus, which is partly contorted and tapering towards the transition to the flagellum. The flagellum is somewhat tapering, relatively shorter than in Plekocheilus (Eurytus) juliani and P. (E.) mundiperditi (Breure 1978: figs 6─7). The vas deferens is shorter than the length of the penis and epiphallus. Vagina rather short; proximal part of spermathecal duct subcylindrical, its intermediate part widened before distally tapering towards the globose spermatheca. Spermoviduct very contorted; albumen gland relatively long.
Remarks. According to Haas (1955) the type material was preserved first in formalin and later in ethanol. The conservation measures taken by Haas, viz. lacquer on the conchinic layer that began to peel off, have only been partly successful. Of the three paratypes studied, only one has retained the conchinic layer preserved as intended. But as a consequence of the lacquer application, the fine granular sculpture on the last whorl has become almost invisible. The preservation status of the two soft bodies included in the paratype material was rather poor, allowing only studying the genitalia.

Material. Venezuela, Estado Amazonas, Cerro Marahuaka, 2170 m (SMF 5143/ holotype).
Remarks. Only the type material is known, making it difficult to judge any intraspecific variation. The taxonomic placement of this species has thus been somewhat enigmatic, the shape of the aperture and the conspicuous but weak fold setting it apart from other members in the genus. Breure (1978) placed it in the subgenus Eudolichotis because of these characteristics. After restudying the holotype in the context of this revision, it is clear that the granulation on the last whorl is very similar to that of Plekocheilus (Eurytus) tatei. The material of P. (E.) mundiperditi contains a specimen with a similarly shaped aperture that is immature (FMNH 52440). The type of P. (E.) gibber, however, has an expanded lip and a convex fold in the columella, both characteristics of maturity. This species is here placed in the Plekocheilus (Eurytus) juliani -group, awaiting further anatomical or DNA studies; see also the discussion part below. Because of this new combination, Antitragus Oberwimmer, 1931 —which was erected solely for this species—should now be considered a junior subjective synonym of Eurytus Albers, 1860.

(Figs 6 H─J, 9J)
Diagnosis. A species characterized by the obliquely descending zig-zag streaks; surface hardly shining, with spiral lines of dot-like granules on the last whorl.
Description. Shell 35 mm (further dimension given in Table 1), 1.7 times longer than wide, imperforate, ovate, sides hardly convex, rather thin. Colour pale yellowish brown, with descending, somewhat oblique stripes of reddish-brown, broken up into separate stripes of different length; upper whorls lighter, corneous, eroded. Surface hardly shining, upper whorls with growth striae, on the penultimate and ultimate whorls transferring into spiral lines of dot-like granulation, more oblong towards the aperture. Protoconch smooth (eroded). Whorls 4.5, rather flat, the last whorl somewhat swollen, suture somewhat impressed, hardly descending in front. Aperture ovate, somewhat skewed, the colour pattern from the outside shining through, 1.7 times longer than wide, 0.65 times the total length; peristome thin and hardly reflexed, whitish with a hue of pink. Columellar margin straight, entering the aperture with a weak fold, hardly dilated and somewhat receding. Parietal wall with a thin, translucent callus.
Type material. Venezuela, Estado Amazonas, Cerro Yapacana, 800 m, J. Cerda leg., 21.ii.1978. Holotype RMNH 112031.
Comparison with other taxa. Differs from P. (E.) huberi spec.nov. by (1) the less descending last whorl; (2) by the different granulation on the last whorl; (3) being less slender. It may also be compared to P. (E.) gibber, from which differs in (1) having the last whorl less descending in front; (2) having the suture less impressed; (3) the different shape of the aperture.
Remarks. Only a subadult specimen is known. The colouration and especially the sculpture of the last whorl (Fig. 24J) sets it apart, but it seems most closely allied to the species with which it is compared above.
Etymology. The name refers to the type locality, Cerro Yapacana, an isolated tepui.

Bulimus coloratus Nyst, 1845: 228, figs 2a─b. Type locality: la province de Cumana, dans la Colombie [sic, Venezuela, Estado Monagas].
Material. Venezuela, Estado Amazonas, Río Negro, A.A. Olsson leg., 1945 (UF 184700/1).
Remarks. The label “ Venezuela, Rio Negro” is not very conclusive about the precise locality where this specimen was found. It could refer either to the District Río Negro or to the borders of the river with the same name, both in the southwestern part of Estado Amazonas. In the latter case it would imply that the locality is at ca. 100 m elevation. In the former case it covers an area of 37.903 km 2, which partly consists of uplands and highlands (including the Cerro de la Neblina massif). Pilsbry (1895: 75) quotes “La Esperanza estate, near Rio Negro” on the authority of Bland, suggesting a lowland occurrence; I do, however, not know if Bland ever collected in the Colombian-Venezuelan border region near the Río Negro. This is the southernmost record for this species, which is widely distributed in Colombia (Borrero, personal communication) and has been reported from north-western Venezuela by Arias (1953).

description: Plekocheilus (Eudolichotis) sinuatus (Albers, 1854)
(Fig. 6 K)
Bulimus sinuatus Albers, 1854: 32. Type locality: Venezuela; lectotype ZMB 101794 (Köhler 2007).
Material. Venezuela, Estado Amazonas, 10 km S Río Autana, 4° 44’ N 67° 33’ W, 100 m, O. Huber leg., 2.vii.1979 (RMNH 112032 /2).
Shell dimensions are given Table 1.
Remarks. This species is reported here for the first time from the Venezuelan Guayana area. Hitherto it was only known from the Cordillera de la Costa in northern Venezuela (Baker 1926, Thompson 1957, Breure 1976). There it was found in cloud forest at 1000 m elevation and the current finding in the lowland was unexpected. It is closely allied to the somewhat smaller P. (E.) euryomphalus (Jonas, 1844), which has been reported from the Roraima savannah in Guyana (Solem 1964).

(Fig. 8 D─F)
Plecocheilus (Eurytus) steyermarki Haas, 1955: 377, fig. 79. Type locality: Venezuela, State of Bolívar, northwest part of Chimantá massif, plateau below the summit of Apacara tepui, 1800 m; holotype FMNH 49735.
Material. Venezuela, Estado Bolívar, northwest part of Chimantá massif, plateau below the summit of Apacará-tepui, 1800 m (FMNH 49735/ holotype).
Remarks. This species has the same white line bordering the suture as Drymaeus (D.) rex spec.nov., but is decidedly smaller. The very faint pinkish border lining the inside of the aperture behind the white lip clearly links both species. The thread-like fold of the columella mentioned by Haas is, however, much weaker than those in the aberrant specimens of D. (D.) rex mentioned below. It is, just as most specimens of D. (D.) extraneus Haas, 1955, without distinct colour pattern and occurs on the same massif. However, it is smaller and more pointed, having straight sides and some incomplete, dark brown axial streaks on the pale ground colour.

Bulimulus (Lissoacme) extraneus Haas, 1955: 382, fig. 82. Type locality: Venezuela, State of Bolívar, northwest part of Chimantá massif, summit of Apacara tepui, ca. 2100 m; holotype FMNH 49736.
Drymaeus (Drymaeus) griffini Haas, 1955: 383, fig. 83. Type locality: Venezuela, State of Bolívar, Chimantá massif, western side of Abacapa tepui, drainage of Río Abacapa, ca. 1300 m; holotype FMNH 49734. New synonymy.
Material. Venezuela, Estado Bolívar, northwest part of Chimantá massif, summit of Apacará-tepui, 2100 m, J.A. Steyermark leg., 20─ 22.vi.1953 (FMNH 49736/ holotype); Ibidem, along trail between Río Tirica and lower summit camp, 1800 m, J.A. Steyermark & J.J. Wurdack leg., 26.ii.1955 (FMNH 52444/ 1 juv. paratype); Idem, west side of Abacapá-tepui, 1189 m, J.A. Steyermark & C. Griffin leg., 13.iv.1953 (FMNH 49734/1). Shell dimensions are given Table 1.
Remarks. Upon restudying the type material, also in the context of the material from Cerro de la Neblina, I have come to the conclusion that this species belongs to what I would like to call the Drymaeus (D.) steyermarki -group; see discussion below. D. (D.) extraneus resembles in shell shape most closely D. (D.) rex, but it is smaller, with the aperture less broad. The type specimens are unicoloured. D. griffini —occurring on the same massif—proves to be synonymous; the name extraneus has page priority. The holotype of griffini is immature, but shows that also a banded colour pattern is possible in this taxon. The original label of D. griffini reads “ Venezuela Botanical Expedition, 1953, Camp 33900, drainage of Rio Abacapá, western side Abacapátepui”. I have been unable to obtain more information from field notes made during the expedition.

Supplementary diagnosis.
Following anatomical examination of specimens representing 15 species and subspecies, no noteworthy variations were discerned in the sclerites of female external genitalia and the shape of spermathecae across different species within this genus. Consequently, detailed descriptions of female external genitalia and spermathecae for these species were omitted, and instead, a summary diagnosis encompassing the genus is provided (Fig. 6). Comprehensive information and illustrations of the anatomical samples are available in the supplementary material (Suppl. materials 1, 2). Paratergites (pt.) banded or lamellar. Crosspiece (cp.) indistinct or distinct, with a small protuberance that points towards the posterior lobes of valvifer II (p. l.). The posterior lobes of valvifer II fuse with the anterior arch (aa.) forming a circinate structure. Posterior lobes of valvifer II well-sclerotized or not, curved apically. The first valvule (v. I) long, slightly curved, with more pronounced lateral sclerotization. Basal part of valvifer II (v. II) and valvifer III (v. III) enlarged. The spermathecal plate (sp. pl.) well-sclerotized, narrow, depressed downward in the middle. Basivalvula (bsv.) symmetrical, with two lobes narrow. Each lobe with curved anterior margins, curly lateral margins, and round posterior margins. The spermatheca (sp.) consists of a large spherical ampulla and a short spermathecal duct. With or without a curved and elongated duct attached to the ampulla. The vestibular sclerite (vst. s) shaped like the letter “ W ”, with three protrusions. The subgenital plate (SVII) densely setose, posterior margin bulging and protruding, with middle part slightly concave inward or not.
