Patagonian Pipefish || DOI: 10.1111/jfb.14056 

Abstract
A new species of pipefish Leptonotus vincentae sp. nov. (Syngnathidae) is described on the basis of 12 specimens found in shallow waters (<2 m depth) of San Antonio Bay, Patagonia, Argentina, in the south‐west Atlantic Ocean. The species is distinguished from congeners by the combination of: dorsal‐fin rays 30–33, pectoral‐fin rays 12–13, trunk rings 18–19, tail rings 43–46, subdorsal rings (2–4) + (5.5–8) = (8.5–10), head length 13–14% standard length, snout length 35–55% head length and snout depth 21–30% in snout length. Although this species has often been mistaken for Leptonotus blainvilleanus, most diagnostic characters of the two species differ. Both species are clearly distinguished by their snout length. L. blainvilleanus has a relatively longer snout than L. vincentae sp. nov. The new species is similar to a south‐west Pacific species, Leptonotus elevatus. However, L. vincentae sp. nov. differs from this species in that it exhibits a lower number of dorsal‐fin rays and a relatively longer head.

Keywords: Atlantic Ocean, Leptonotus blainvilleanus, new species, San Antonio Bay, sexual dimorphism, Syngnathiformes



Leptonotus vincentae sp. nov. 

Etymology: The species is named after Amanda Vincent, whose work on conservation of syngnathids has increased our chances of having healthy populations of these fishes in the threatened seas of the world.

Abstract
Despite its recognition since the early 1900s, the agamid lizard Pseudocalotes austeniana remains known based on 3 vouchered specimens only from the East Himalaya, and little is known about its general biology. During herpetological surveys of Tibet, China, we collected 3 specimens of P. austeniana from Medog County, southeastern Tibet, including the first juvenile specimen ever vouchered. We provide a detailed description based on new material of this enigmatic species, report on a range extension of 400 km northeastward from its type locality, its ontogenetic shift, and clutch size.

Identification. The recently collected adult and juvenile specimens from Tibet resemble closely the pholidosis characteristics of the vouchered holotype and topotypic specimen of Pseudocalotes austeniana (Table 1). In summary, these specimens are identified as P. austeniana based on the following morphological characters (following Mahony 2010): (1) tympanum exposed; (2) sub-ocular scale row singular, or multiple but one distinctively enlarged; (3) head robust, HW/HL > 59.7%, HD/HW > 72%, HD/HL > 43%; (4) distinct, strongly-developed cranial ridges present on dorsal and lateral surfaces of occipital region of head, forming rectangular, convex areas on temporal region of head and triangular concave area on posterior lateral region of head; (6) postorbital and postoccipital spines absent; (7) nuchal crest in triangular shape or short lanceolate shape, not strongly differentiated from dorsal crests; (8) mid-dorsal scale count less than 39; (9) longitudinal gular fold present, highly developed in dewlap, with a distinct, pointy tip toward posterior end; (10) transverse gular fold absent; (11) dorsal scales heterogeneous in size and shape, flat, feebly keeled or smooth, arranged irregularly in most parts, some enlarged ones in approximate transverse rows; (12) enlarged scales of dorsum not arranged into clear dorsolateral or V-shaped rows; (13) ventral body scales smooth or feebly keeled, larger than background dorsal scales, distinctively heterogeneous in size and shape, irregularly arranged; (14) antehumeral fold present; and (15) axillary fold present.

Distribution range. Prior to our observations of Pseudocalotes austeniana in the field, the species was thought to be a rare endemic to the southern parts of Southern Tibet (Mahony 2010, Venugopal 2010, 2013), and the species was not officially listed as a member of the Chinese herpetofauna (Zhao and Jiang 1977, Zhao and Adler 1993, Zhao et al. 1999, Cai et al. 2015). However, the newly discovered populations represent a range expansion of about 400 km northeastward from the species’ previous range limits in the East Himalaya. Given the recognized habitat connectivity and similar environment spanning this region, it is likely that P. austeniana is currently, or once was, distributed continuously across this area. Future survey efforts for this species should focus on habitat to the west in Bhutan. Additional studies of this enigmatic and secretive lizard are needed to better understand its ecology, population densities, and full geographic distribution.

[Mollusca • 2019] Olea hensoni Eggs Sunny-side Up: A New Species of Olea, An Unusual Oophagous Sea Slug (Gastropoda: Heterobranchia: Sacoglossa), from the western Atlantic

Abstract
Nearly all of the recognized species of sea slugs in clade Sacoglossa (about 300 taxa) are herbivorous, using a uniseriate radula in suctorial feeding. The only exceptions are a pair of monotypic genera in the ceratiform family Limapontiidae: Olea Agersborg, 1923 from the northeastern Pacific, and Calliopaea d’Orbigny, 1837 from the northeastern Atlantic coast of Europe and the Mediterranean. Both genera feed on the eggs of other heterobranchs, notably cephalaspideans, and lack cerata on the anterior dorsum. Major differences are that C. bellula d’Orbigny, 1837 has more cerata than O. hansineensis Agersborg, 1923, a more typical radula with ascending and descending rows of fully-formed teeth, and a much longer penial stylet. Here, we describe a new egg-eating sacoglossan species from the subtropical Gulf of Mexico coast of Florida, U.S.A. Phylogenetic relationships inferred from analyses of a four-gene dataset including 219 sacoglossan species indicated the new taxon (Olea hensoni n. sp.) belongs to Olea. The generic placement of the new species is also supported by its highly reduced radula and comparatively short penial stylet. A full description of the reproductive, digestive, and nervous systems is also provided. Finding a new Olea species in the warm waters of the western Atlantic was surprising, given the genus was previously known only from the cold northern Pacific, and suggests further diversity in oophagous sacoglossans may await discovery.

Keywords: Gastropoda, biogeography, integrative taxonomy, oophagy, radula, species discovery, systematics


Olea hensoni feeds on the eggs of other slugs and snails. Researchers are unsure if the slug's diet of eggs is an advantage over plant-eating slugs or if it may ultimately limit the evolution of its lineage, becoming a dietary dead-end.

[Botany • 2019] Gymnosporia sekhukhuniensis (Celastraceae) • A New Species from South Africa


Gymnosporia sekhukhuniensis Jordaan & A.E.van Wyk

in Jordaan & van Wyk, 2019. 

Abstract
Gymnosporia sekhukhuniensis, a new species from north-eastern South Africa, is described, illustrated, mapped, and compared with closely related species. It belongs to Gymnosporia sect. Buxifoliae, more specifically Group 1, the members of which are characterized by the capsules being (2)3(4)-valved, rugose or verrucose, and the seeds partially covered by the aril. The new species has a restricted distribution range and is near-endemic to the Sekhukhuneland Centre of Endemism. This biogeographical region rich in restricted-range plants is more or less congruent with surface outcrops of mafic and ultramafic igneous rocks belonging to the Rustenburg Layered Suite of the eastern Bushveld Complex. The range of the new species shows marginal intrusion into the far northern part of the nearby Wolkberg Centre of Endemism, where it is associated with dolomites of the Malmani Subgroup. Gymnosporia sekhukhuniensis is a suffrutex mainly associated with rocky outcrops in open savannah. Diagnostic characters include its dwarf habit (up to 1.6 m tall), capsules that are relatively small (5–8 mm long), woody, scaly-rugose, with hard pointed apices, and leaves that are very laxly arranged on the stems, with some often present on the thorns. Also included is a key to the 10 currently accepted species in G. sect. Buxifoliae Group 1. The taxonomic significance of capsule and seed characters for demarcating sections and species in the genus Gymnosporia is emphasized.

Gymnosporia sekhukhuniensis Jordaan & A.E.van Wyk, sp. nov. 

Closely related to Gymnosporia heterophylla (Ecklon & Zeyher 1834–1835: 120) Loesener (1892: 207), with which it shares being a suffrutex with the stems angular-ribbed and in having capsules with a rugose surface, but from which it differs in the leaves being laxly arranged on the stems (vs. very densely and compactly), usually longer than 35 mm (vs. usually shorter than 20 mm), and capsules with apices apiculate (vs. rounded). Also related to the widespread G. buxifolia (Linnaeus 1753: 197) Szyszylowicz (1888: 34), from which it differs in being a suffrutex up to 1.6 m tall (vs. usually a shrub or tree more than 2 m tall), with stems angularribbed (vs. terete) and capsules 5–8 mm long (vs. usually less than 5 mm long), with apices apiculate (vs. not apiculate).


Etymology:— The specific epithet is derived from Sekhukhuneland, the region to which the species is largely confined. 

Distribution:— Occurs along the north-eastern Great (Drakensberg) Escarpment of the Limpopo and Mpumalanga Provinces of South Africa and is considered near-endemic to the Sekhukhuneland Centre of Endemism, with marginal intrusion into the far northern adjoining part of the Wolkberg Centre of Endemism (Van Wyk & Smith 2001) (Fig. 3).

Common names:— The proposed common names for this plant are Sekhukhune spikethorn, sekhukhunependoring (Afrikaans).

[Paleontology • 2019] Repeated Evolution of Herbivorous Crocodyliforms during the Age of Dinosaurs

Highlights
• Some extinct crocodyliforms, relatives of living crocodylians, possess complex teeth
• Quantitative analyses suggest some species with complex teeth were likely herbivores
• Herbivorous crocodyliforms evolved at least three times independently
• Some dentitions rival the complexities of living mammal herbivores

Summary
Extinct crocodyliforms from the age of dinosaurs (Mesozoic Era) display an impressive range of skeletal morphologies, suggesting a diversity of ecological roles not found in living representatives. In particular, unusual dental morphologies develop repeatedly through the evolutionary history of this group. Recent descriptions of fossil crocodyliforms and their unusual teeth provide the inferential basis for a wide range of feeding ecologies. However, tests of these hypotheses are hindered by the lack of directly comparable dental morphologies in living reptiles and mammals, thereby preventing an accurate ecosystem reconstruction. Here, we demonstrate, using a combination of the orientation patch count rotated method and discrete morphological features, that Mesozoic crocodyliforms exploited a much greater range of feeding ecologies than their extant relatives, including likely omnivores and herbivores. These results also indicate that crocodyliforms independently developed high-complexity dentitions a minimum of three times. Some taxa possess teeth that surpass the complexities of living herbivorous lizards and rival those of omnivorous and herbivorous mammals. This study indicates that herbivorous crocodyliforms were more common than previously thought and were present throughout the Mesozoic and on most continents. The occurrence of multiple origins of complex dentitions throughout Crocodyliformes indicates that herbivory was a beneficial dietary strategy and not a unique occurrence. Many of these crocodyliforms lived alongside omnivorous or herbivorous synapsids, illustrating an ecological partition that is not observed today.

[Herpetology • 2019] Lost and Found: Taxonomic Revision of the Speckled Skink (Oligosoma infrapunctatum; Reptilia; Scincidae) Species Complex from New Zealand reveals A Potential Cryptic Extinction, Resurrection of Two Species, and Description of Three New Species

Melzer, Hitchmough, Bell, Chapple & Patterson, 2019

Abstract
New Zealand has a diverse skink fauna, comprising 45 described native species, and at least 15 undescribed taxa, within the single genus Oligosoma Girard, 1857. One of the earliest described, and best known, species is the speckled skink, Oligosoma infrapunctatum (Boulenger 1887). Despite a relatively stable taxonomic history for nearly 114 years, recent molecular work has indicated that O. infrapunctatum represents a species complex, comprising numerous genetically divergent, range restricted taxa. We completed the first stage of a taxonomic revision of O. infrapunctatum, conducting a morphological re-evaluation of existing voucher material, and newly collected specimens, and generated a molecular phylogeny for the species complex. This allowed us to distinguish six species: O. infrapunctatum, two species resurrected from synonymy (O. newmani, O. robinsoni), and three new species (O. salmo sp. nov., O. albornense sp. nov. O. auroraensis sp. nov.). The name bearing type population of O. infrapunctatum has not been located again for at least 130 years: it remains to be rediscovered and may already be extinct. Two of the six species here are considered ‘Nationally Critical’ (O. albornense sp. nov., O. salmo sp. nov.) under the New Zealand Threat Classification System, the others are Nationally Vulnerable (O. auroraensis sp. nov.) and At Risk—Relict (O. newmani, O. robinsoni). Further taxonomic work will be required to determine the taxonomy of other speckled skink genetic lineages in the South Island, particularly O. aff. infrapunctatum “cobble”, O. “Hokitika”, O. “Southern North Island” and O. “Westport”.

[Herpetology • 2019] Platypelis ando • A New Yellow-toed Platypelis Species (Microhylidae, Cophylinae) from the Maroantsetra Region, northeastern Madagascar


Platypelis ando
Scherz, Köhler, Vences & Glaw, 2019


Abstract
We describe a new species of arboreal narrow-mouthed frog, genus Platypelis, from Ambodivoangy near Maroantsetra in northeastern Madagascar. The new species, Platypelis ando sp. nov., is characterised by small body size (under 19 mm), a generally rather slender body, yellowish finger and toe tips, and a dark brown dorsal chevron. Its advertisement call is a single, moderately long, high-pitched whistle repeated at regular intervals. It is the sister species of P. ravus from Marojejy National Park, but differs from that species by considerable pairwise genetic distances (7.9%) in a fragment of the mitochondrial 16S rRNA gene, and also in bioacoustic and morphological features, especially the absence of yellow on the posterior abdomen. It is also surprisingly similar in external appearance to Cophyla occultans and C. maharipeo, to which it is not, however, closely related; these species are most easily discerned based on their calls. Platypelis ando sp. nov. joins the ranks of several species recently described from Ambodivoangy with close affiliations to species in the nearby Marojejy National Park, that are still divergent at species level. The species qualifies as Critically Endangered according to the IUCN Red List criteria, in line with other species recently assessed from this area, but we urge that more research be conducted in the nearby forests to extend the range of this and other species known only from Ambodivoangy.

Platypelis ando sp. nov. 

  
Diagnosis: The new species is assigned to the genus Platypelis based on molecular phylogenetic relationships (Fig. 1). Platypelis ando sp. nov. is characterised by the following combination of characters: (1) Small size, with adult male SVL 16.9–18.7 mm; (2) manus with second finger shorter than fourth, pes with fifth toe shorter than third; (3) discs of fingers and toes yellowish to orangish in life; (4) presence of a dark dorsal chevron; (5) presence of dorsal tubercles; (6) short supratympanic dark brown marking; (7) males with prepollical tubercle but lacking a finger-like prepollex as typical for Anodonthyla Müller, 1892.

The new species is distinguished from Platypelis cowanii, P. mavomavo, P. grandis, P. tsaratananaensis, P. pollicaris, P. alticola, P. olgae, P. tuberifera, P. barbouri and P. milloti by considerably smaller size (16.9–18.7 vs >25 mm). Among Platypelis species of similar size, it can be distinguished from P. tetra by its smaller dorsal tubercles, absence of large white spots on the dorsum (vs presence), and presence of a brown chevron-shaped marking on the dorsum (vs absence); and from P. karenae by its brown colouration and dorsal patterning (vs yellow colouration and lack of dorsal patterning), short supratympanic dark brown marking (vs extended along the flank), and less pointed snout. Morphologically and genetically, P. ando sp. nov. most closely resembles P. ravus. It differs from that species in the lack of yellowish colour on its venter (vs present), yellowish to orangish dorsal finger and toe tip colouration (vs brownish), and by a chevron-shaped brown marking on dorsum (vs W-shaped).

Natural history: As is typical for Platypelis species, calling activity was only heard after dusk. ZSM 291/2010 was found calling 1.8 m above the ground. Nothing further is known about the habits of this species, but based on the reproductive ecology of congeners, it is likely to reproduce in phytotelms and have endotrophic nidicolous tadpoles.

Available names: Only two available synonyms of any Cophyla or Platypelis refer to small-sized species that could possibly refer to our new species. Cophyla tuberculata Ahl, 1929 ‘1928’ is currently a synonym of P. grandis. The two syntypes are juveniles according to Blommers-Schlösser and Blanc (1991), but have an SVL of 26 mm, and are therefore larger than the new species. Paracophyla tuberculata Millot & Guibé, 1951 is currently considered a synonym of P. barbouri. The holotype of that species, MNHN-RA-1957.715, differs from our new species in having a more rugose dorsum, broader finger discs, and a darker venter. Additionally, it is from Périnet (=Analamazaotra) in the Central East of Madagascar, more than 400 km south of Ambodivoangy. Blommers-Schlösser and Blanc (1991) concluded that it is conspecific with P. barbouri, and we agree that it is a member of that species complex, which is in need of revision.

Etymology: We dedicate this species to our friend and colleague, Dr. Andolalao Rakotoarison, in recognition of her valuable contributions to the systematics and taxonomy of the Malagasy microhylid fauna. The name is to be treated as an invariable noun in the nominative singular.

Distribution: The new species is reliably known only from the type locality Ambodivoangy, but the species is likely to be more widespread in low altitude forest of the adjacent Makira Natural Park. Glaw and Vences (1992) found a small Platypelis species (assigned to and figured as P. occultans) near Voloina (15.5775S, 49.6042S; voucher specimens ZFMK 52777–52779), ca. 30 km south of the type locality with similar calls and morphology, which is possibly conspecific with Platypelis ando, but further studies are necessary to confirm its identity.
