Abstract

Epidendrum claustralis, a new species of the Rupestre Group is described and illustrated. It is a novelty from the Departments of Junín, San Martín and Amazonas, Peru. It is compared to the most similar species, Epidendrum excelsum. The species is characterized by the entire lip and with two prominent parallel calli that lean towards each other after pollination or the loss of the pollinarium, closing the entrance of the nectary, and thus avoiding another pollination event.

[Paleontology • 2022] Transylvanosaurus platycephalus • A New Ornithopod Dinosaur (Ornithischia: Ornithopoda: Rhabdodontidae) from the Upper Cretaceous of the Haţeg Basin, Romania

Transylvanosaurus platycephalus 

Augustin, Bastiaans, Dumbravă & Csiki-Sava, 2022

DOI: 10.1080/02724634.2022.2133610 

ABSTRACT

Rhabdodontid dinosaurs were a group of medium-sized iguanodontian ornithopods from the Late Cretaceous of Europe. The uppermost Cretaceous continental deposits from the Haţeg Basin of western Romania yielded a very rich assemblage of vertebrates including abundant rhabdodontid remains, which have been exclusively referred to the genus Zalmoxes thus far. Here we describe a new rhabdodontid dinosaur, Transylvanosaurus platycephalus gen. et sp. nov., from the uppermost Cretaceous of the Haţeg Basin. The holotype of the new taxon was discovered in early–late Maastrichtian strata near Pui in the eastern part of the basin and comprises the articulated basicranium and both frontals. Transylvanosaurus differs from all previously reported rhabdodontids in having particularly wide and crested frontals, elongated and straight paroccipital processes that make only a gentle lateral curve and project mostly posterolaterally, prominent and massive prootic processes that extend mainly anterolaterally and ventrally, wide and crest-like basal tubera that meet the long axis of the braincase at a very flat angle, widely splayed basipterygoid processes that extend mainly ventrolaterally and slightly anteriorly, as well as a well-developed notch on the lateral side of the basicranium that is continuous, straight, and inclined anteroventrally. Phylogenetic analyses employing two different datasets consistently recovered the new taxon within the Rhabdodontidae, at the base of the iguanodontian radiation. Based on the morphological comparisons presented herein, we propose a particularly close relationship between Transylvanosaurus and Rhabdodon from southern France, which in turn provides evidence for a more complex biogeographic history of the Rhabdodontidae than previously thought.

Abstract

 Nemacheilus cacao, new species, is described from the middle Mekong basin in Laos. It differs from all other species of Nemacheilus by having an incomplete lateral line; and adult males having a plain grey-brown body and head (except ventral side), and with extensive tuberculation on the flank, on the dorsal side of the pectoral fin and on the head and nape. The phylogenetic position of N. cacao in the Selangoricus clade of Nemacheilus, as a sister species to N. platiceps, is supported by the presence of bars on the body in juveniles and females as well as by genetic data.

 Key words. Cobitoidea, taxonomy, Khammouan, Nam Thorn, Xe Bangfai

Nemacheilus cacao, new species

Diagnosis. Nemacheilus cacao is distinguished from all other species of the genus except N. platiceps in having an incomplete lateral line reaching between verticals of pelvicfin origin and of anus, with 33–49 pores (vs. complete). Nemacheilus cacao is most easily distinguished from N. platiceps by its colour pattern, with a uniform dark brown body in adult males. In contrast, N. platiceps has 12–16 narrow bars on the flank, clearly distinct at all sizes and both sexes. In addition, N. cacao is distinguished from N. platiceps by males having: a conspicuous suborbital flap (vs. poorly developed); dorsal surface of first 3–7 pectoral-fin rays covered by densely-set small tubercles; flank with a patch of scales each with a small tubercle (vs. absence of tubercles on pectoral fin and flanks).

Etymology. From Theobroma cacao, the cacao tree whose seeds are used to produce chocolate; itself derived from kakawa in some ancient Mesoamerican language (Kaufman & Justeson, 2007). A reference to the chocolate brown colour of large males. A noun in apposition, indeclinable

Summary

Clerodendrum peninsulare, a species restricted to upper peninsular Thailand, is described and illustrated as new to science. It has long pendulous inflorescences with white flowers similar to those of C. angustipetalum, C. nutans and C. umbratile which are also found in peninsular Thailand, but it differs in its calyx and corolla. The conservation status of C. peninsulare is assessed as Near Threatened (NT). Clerodendrum palmatolobatum, a species previously thought to be restricted to Cambodia and Vietnam, is reported in Thailand and Laos and is lectotypified. It is illustrated and compared with the morphologically similar species C. intermedium, C. japonicum and C. paniculatum. The conservation status of C. palmatolobatum is assessed as Least Concern (LC).

Abstract

Two novel species in Begonia sect. Platycentrum from northwestern Vietnam, B. minhaniae and B. dieuanhiae, are described and illustrated. Both species superficially resemble B. phouchomvoyensis in their rhizomatous habit, plain green ovary and leaves, 4-tepaled staminate flowers and 3-locular ovaries, but they can be clearly distinguished from the latter by several morphological characters such as morphology of vestiture, fewer anthers (those of B. minhaniae are ca. 15 vs. ca. 45 in B. phouchomvoyensis) and more tepals of pistillate flower (5 tepals in B. dieuanhiae vs. 3 tepals in B. phouchomvoyensis). These two novel discoveries highlight the growing body of research showing the rich and varied biodiversity of Begonia in the flora of Vietnam.

[Herpetology • 2022] Afroedura pundomontana & A. otjihipa • Rock Island Melody Remastered: Two New Species in the Afroedura bogerti Loveridge, 1944 Group (Squamata: Gekkonidae) from Angola and Namibia

Abstract

Newly collected material from northern Namibia’s Otjihipa Mountains and west-central Angola allowed us to revisit the Afroedura bogerti Loveridge, 1944 group. The employment of additional gene markers, including nuclear markers, allowed us to identify two new species in the group and infer species boundaries and potential speciation events in Afroedura from southwestern Africa. The new Namibian material is recovered as a sister species to A. donveae, from which it differs mostly by the colour of the iris (copper versus black) and dorsal colouration. Material from the first elevational gradient of the escarpment in Benguela Province, Angola was found to be more closely related to A. bogerti than A. wulfhaackei. The differences between these two species are more subtle, although the new species exhibits higher mid-body scale rows (79.5 versus 74.8), different dorsal colouration and supranasal scales always in contact (versus 57% in contact).

Bocoio Flat Gecko (English) 

Osga-achatada do Bocoio (Portuguese)

Note: According to Branch et al. (2021), historical material from near Bocoio in Benguela Province, Angola clustered morphologically with A. wulfhaackei. However, due to the occurrence at lower elevations and being isolated from other known populations of Afroedura it was suggested that the status of this population required further investigation (Branch et al. 2021). Newly-collected material allowed for its re-assessment within a wider phylogenetic framework, and it was determined that it represented a novel lineage, related to A. bogerti and not A. wulfhaackei, as initially hypothesised. It is therefore described below as a new species.

Diagnosis: A member of the greater ‘transvaalica’ group, possessing two pairs of enlarged scansors per digit, and a strongly verticillate and flattened tail (Jacobsen et al. 2014). As part of the A. bogerti group it differs from other members of the ‘transvaalica’ group by having 78–82 midbody scale rows (versus 97–102 in A. gorongosa, 113–120 in A. loveridgei, 102–119 in A. transvaalica); and rostral excluded from the nostril (in contact in A. gorongosa) [Note: in Branch et al. (2021) it was incorrectly recorded that the rostral is in contact with the nostril in the A. bogerti-group]; with the supranasals always being in contact (separated by 1–3 granules in A. gorongosa; always in broad contact in A. loveridgei; usually in broad contact in A. transvaalica ~ 3–18%); and in having 13–15 scales between the anterior borders of the eyes (19–22 in A. gorongosa; 15–19 in A. loveridgei; 15–20 in A. transvaalica) (comparative data fide Branch et al. 2017, 2021).

....

Etymology: The new species is named in reference to the area where it was found. The region lies on top of a ridge known as Morro do Pundo that translates to the ‘Hills’ or ‘Mountain’ of the Baboons. The name thus comprises two parts: pundo (= baboon) and montana (= mountain).

Part of the A. bogerti group which differs from other members of the ‘transvaalica’ group by having less than 72 mid-body scale rows (vs. 97–102 in A. gorongosa, 113–120 in A. loveridgei, 102–119 in A. transvaalica); rostral excluded from the nostril (in contact in A. gorongosa); supranasals always in contact (separated by 1–3 granules in A. gorongosa; always in broad contact in A. loveridgei; usually in broad contact in A. transvaalica ~ 3–18%); and 15–16 scales between anterior borders of the eyes (19–22 in A. gorongosa, 15–19 in A. loveridgei, 15–20 in A. transvaalica) (comparative data from Branch et al. 2017, 2021).

Etymology: The new species is named in reference to the area it was collected, namely Otjihipa Mountains in northern Namibia.

Resumo: O material recém-colectado nas montanhas Otjihipa do norte da Namíbia e no centro-oeste de Angola permitiu-nos revisitar o grupo Afroedura bogerti Loveridge, 1944. O emprego de marcadores genéticos adicionais, incluindo marcadores nucleares, permitiu-nos identificar duas novas espécies no grupo e inferir limites para separar as espécies e potenciais eventos de especiação nos Afroedura do sudoeste Africano. O novo material da Namíbia é recuperado como espécie mais próxima de A. donveae, do qual difere sobretudo pela cor da iris (acobreada ao invés de negra) e pela coloração dorsal. Ao passo que o material obtido no primeiro gradiente topográfico da escarpa na província de Benguela, Angola, revelou ser mais relacionado com A. bogerti do que com A. wulfhaackei. As diferenças entre estas duas espécies são mais subtis, muito embora as novas espécies axibam maior número de escamas a meio do corpo (79.5 em vez de 74.8), diferente coloração dorsal e escamas supranasais sempre em contacto (em vez de apenas em contacto em 57%).

Abstract 

In recent years, taxonomic research of the genus Diploderma has made great progress, but there are still areas lacking relevant investigations. During 2020–2021, we carried out survey of reptile diversity in and around the Shaluli Mountains and collected some specimens of Diploderma. Of which, based on systematics inferred from mitochondrial ND2 gene sequence and morphological data, three new species were recognized: Diploderma daochengense sp. nov. from the Shuiluo River and Muli River valleys in southeastern Daocheng County, D. xinlongense sp. nov. from the upper-middle valleys of the Yalong River in Xinlong County, and D. kangdingense sp. nov. from the Yalong River middle valley and Liqiu River valley. Specifically, these three new species formed three monophyletic lineages with strongly supported and nested into the subclade I of the Bayesian and Maximum Likelihood trees. The uncorrected mean genetic distance between these new species and their closely related species was 4.3% (D. xinlongense sp. nov. vs. D. panchi), 3.4% (D. daochengense sp. nov. vs. D. yulongense) and 5.5% (D. kangdingense sp. nov. vs. D. bowoense), higher than many pairs of species of Diploderma. With respect to the morphology, D. daochengense sp. nov. can be easily diagnosed from D. yulongense by having smooth upper edge of the dorsolateral stripes, cyan or dark olive green to yellow gular spots in both sexes and light yellow or white ventrolateral body in males; D. xinlongense sp. nov. can be easily diagnosed from D. panchi by having cyan gular spot in both sexes; D. kangdingense sp. nov. can be easily diagnosed from D. bowoense by having more T4S 20–25 (average 23), more F4S 16–20 (average 17) and yellow to light yellow ventrolateral body, yellow gular spot present in males. To date, the number of species of the genus Diploderma has increased to 40, of which 37 species have been known in China.

ABSTRACT

A new genus and new species of potamid crab, Gurumon gurumayum gen. et sp. nov., are described from the Arunachal Pradesh State of northeastern India. Gurumon gen. nov. has affinities with Abormon Mitra, Pati & Ng, 2021, Pararanguna Dai & Chen, 1985, and some species of Potamiscus Alcock, 1909, but the new genus can easily be differentiated from them mainly by its low external orbital angle, the relatively stouter exopod of the third maxilliped, and the relatively broader male pleonal somite 6. Their male first gonopods are also different from each other. Counting Gurumon gurumayum gen. et sp. nov., India is currently known for ten genera and 24 species of potamiscine freshwater crabs, and Arunachal Pradesh for eight genera and 11 species of these crabs. The current nomenclatural problems with Potamiscus are also discussed.

Genus Gurumon gen. nov.

Type species: Gurumon gurumayum sp. nov., 

by present designation; gender neuter.

Diagnosis: Small adult size (adult CW < 15 mm). Carapace transversely ovate; dorsal surface generally smooth, glabrous, conspicuously arched; epigastric cristae low, visible as 2 broad protuberances; postorbital cristae indiscernible; external orbital angle indistinct, low; epibranchial tooth very low; cervical grooves barely visible (Figs 1A–B, 2A, E, H, 3A). Epistome posterior margin with well-developed, triangular medial tooth (Fig. 1B). Antennules short, folded in longitudinally broad fossae; antennae vestigial (Fig. 1B). Mandibular palp 3 segmented; terminal segment simple, undivided (Fig. 2B). First, second maxillipeds each with short flagellum on exopod; third maxilliped exopod relatively stout, tapered, reaching beyond anterolateral angle of ischium, completely lacking flagellum (Figs 1B–C, 3B). Chelipeds smooth, glabrous (Figs 1A, C, 2A, E, H). Ambulatory legs glabrous, slender; merus (P2–P5) elongated (Figs 1A, C, 2A, E, H). Male s2/s3 deep, reaching lateral margins; s3/s4 indiscernible; s7/s8 lacking transverse ridge (Figs 1C, 2C–D, 3C). Male pleon broad, with distinctly broader pleonal somite 6 (Figs 1C, 3C–D). Male telson tongue-shaped, with concave lateral margins (Figs 1C, 3C–D). G1 stout, long; flexible zone small; terminal segment stout, cylindrical, long, ca 0.6 × combined length of flexible zone and subterminal segment, curved outwards, dorsal flap absent; subterminal segment stout (Figs 2C, 3E, 4A–B). G2 longer than G1; distal segment long, ca 0.4 × as long as basal segment (Figs 2C, 3F, 4C). Vulvae on S6 located apart from each other (VD/SW = ca 0.25), open mesially, subovate, large (Fig. 2G).

Etymology: The genus is named in the honour of Dr Shantabala Devi Gurumayum for her extensive work in aquatic biology, in arbitrary combination with the genus name Potamon Savigny, 1816. The gender of the generic name is neuter.

Gurumon gurumayum sp. nov.

Etymology: The species epithet is the family name of Dr Shantabala Devi Gurumayum, an Indian zoologist who kindly collected and provided the crab specimens for the present study. The species name is treated here as a Latin noun in apposition.
