Abstract

 A new species, Catasetum caquetense from the Caquetá department of the Colombian Amazonia, is described and illustrated. Catasetum caquetense is morphologically distinct from similar species such as C. tuberculatum in its rectangular, entire, denticulate, prominent apiculate basal callus surrounded by inconspicuous crown-shaped protrusions with an extra callus towards the apex that partially narrows towards the midlip. Information about its distribution, ecology, habitat, and taxonomic comments on morphologically similar species is also provided. With this addition, the genus comprises eight species in the department of Caquetá.

Catasetum caquetense R.A.Calderón-Álvarez & M.Bonilla, sp. nov. 

 Diagnosis: Catasetum caquetense is morphologically similar to C. tuberculatum Dodson; however, it differs by the rectangular lip (vs. elliptical), with smooth to somewhat denticulate edges (vs. entire), the abaxial surface not entirely tuberculated (vs. fully tuberculated lip on the abaxial surface), and a prominent apiculate basal callus (vs. slightly prominent), which is encircled by minor crown-shaped protrusions, with an extra callus towards the apex that partially narrows towards the saccate mid-lip, a characteristic absent in C. tuberculatum.

Etymology: The specific epithet “caquetense” refers to the Caquetá Department in Colombia, which is the geographical location where the species was discovered.

[Botany • 2023] Pinalia campanulata (Orchidaceae) • A New Species of Pinalia with bell-shaped flowers from the Mossy Forest of southern Mindanao, Philippines

 Pinalia campanulata Saavedra & Pitogo, 

in Saavedra, Pitogo et Boos, 2023. 

DOI: 10.11646/phytotaxa.626.2.2

 

Abstract

We present the first orchid species described from the Mount Busa Key Biodiversity Area (KBA 196) in southern Mindanao, Philippines. The new species was discovered growing on moss-covered tree trunks in the upper montane forest. It is primarily distinguished among the genus Pinalia by its very short inflorescence that bears few, closely spaced and relatively large campanulate flowers with trilobed, weakly keeled labellum and a dentate callus on disc. The discovery of this species brings the total number of Pinalia in the Philippines to 39. More importantly, it highlights the need for more field-based research on the flora of southern Mindanao to alleviate knowledge shortfalls that continue to limit our understanding of the region’s biodiversity.

Pinalia campanulata Saavedra & Pitogo sp. nov. 

Diagnosis:—The new species is related to Pinalia polyura (Lindl.) Kuntze in Ames (1905: 95) but with a much shorter inflorescence (1–4 vs. 10–14 cm) bearing fewer flowers (10–18 vs. up to 40), oblong-elliptic sepals and petals (vs. ovate- to triangular-lanceolate lateral sepals and cordate petals), trilobed labellum (vs. unlobed) that is weakly keeled (vs. bicarinate) and having a deltate callus on disc (vs. purple tubercle). The new species is also distinguished by its prominently campanulate flowers.

Etymology:—The specific epithet, campanulata, is reminiscent of the prominently bell-shaped flowers of this species that do not open widely. To our knowledge, the shape of P. campanulata flowers is quite unique among Pinalia species.

[Herpetology • 2019] Amolops ottorum • A New Species of Amolops (Anura: Ranidae) from Vietnam

 Amolops ottorum 

Pham, Sung, Pham, Le, Ziegler & Nguyen, 2019 

 Son La Sucker Frog | Ếch bám đá sơn la  ||  LKCNHM.nus.edu.sg/rbz/volume-67 

Abstract

 A new species of Amolops is described from northwestern Vietnam based on morphological differences and molecular divergence. Morphologically, Amolops ottorum, new species, is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: size small (SVL 47.5–48.2 mm in females); head longer than wide; vomerine teeth absent; snout short (SE/SVL 0.14–0.15); tympanum dark brown, small (TD/ ED 0.36–0.37 in females); skin smooth; supratympanic fold absent; dorsolateral fold absent; webbing formula I 0―1/3 II 0―1 III 0―1 IV 2―0 V; in life, dorsum green with some dark brown spots; flanks with irregular dark markings; head and body with irregular dorsolateral cream stripe; dorsal surface of fore and hind limbs green with dark crossbars; throat, chest, anterior part of belly light-cream with brown dots; and posterior part of belly cream. In phylogenetic analyses, the new species is weakly supported as a sister taxon of Amolops tuberodepressus, and approximately 5.6% divergent from it based on a fragment of the cytochrome b gene. 

Key words. Amolops, molecular phylogeny, Muong La, new species, Son La Province, taxonomy

Amolops ottorum, new species

Diagnosis. The new Amolops species from Son La Province is assigned to the A. mantzorum species group on the basis of the following characters: the absence of a dorsolateral fold and the absence of circummarginal groove on the disc of the first finger (Fei et al., 2009, 2017). The new species is also supported as a member of the A. mantzorum species group based on the molecular analyses (Fig. 2). Amolops ottorum, new species is distinguishable from its congeners by a combination of the following morphological characters: (1) size small (SVL 47.5–48.2 mm in females); (2) head longer than wide; (3) vomerine teeth absent; (4) snout short (SE/ SVL 0.14–0.15); (5) tympanum dark brown, small (TD/ED 0.36–0.37 in females); (6) skin smooth; (7) supratympanic fold absent; (8) dorsolateral fold absent; (9) webbing formula I 0–1/3 II 0–1 III 0–1 IV 2–0 V; (10) in life, dorsum green with some dark brown spots; (11) flanks with irregular dark markings; (12) head and body with irregular dorsolateral cream stripe; (13) dorsal surface of fore and hind limbs green with dark crossbars; (14) throat, chest and anterior part of belly light-cream with brown dots, posterior part of belly cream.

Distribution. Amolops ottorum, new species is currently known only from the type locality in Muong La District, Son La Province, Vietnam (Fig. 1). 

Etymology. The species name, ottorum, is the plural possessive form of Mrs Otti Ziegler and Mr Otto Ziegler, who facilitated herpetological research collaborations between Vietnam and Germany. For the common names we suggest Son La Sucker Frog (English) and Ếch bám đá sơn la (Vietnamese). 

Ecological notes. The holotype was collected at 1905 hours on leaves, ca. 1.5 m above the ground and the paratype was collected at 500 hours on a rock nearby a stream. The surrounding habitat was secondary forest of medium and large hardwoods mixed with shrubs (Fig. 6). Air temperature was 17–22°C and relative humidity was 80–85%. Other amphibian species found at the site were Leptobrachium sp., Leptobrachella sp., Quasipaa delacouri (Angel), Odorrana jingdongensis Fei, Ye & Li, and Kurixalus bisacculus (Taylor).

[Botany • 2023] Cotoneaster densiflorus (Rosaceae) • A New Species from western Sichuan, China

Cotoneaster densiflorus M.W. Li, Q. Fan & W. B. Liao, 
 

in Li, Li, Lu, Mo, Ding, Chen, Lai, Zhang, Liao et Fan, 2023. 

 DOI: 10.3897/phytokeys.236.111819

Abstract

Cotoneaster densiflorus, a new species of Rosaceae from western Sichuan, China, is described and illustrated. Morphologically, we inferred that the new species belongs to Cotoneaster Ser. Salicifolii sensu Yü et al. (1974) in the Flora of China and Fryer and Hylmö (2009). This species is most similar to C. salicifolius, but differs in its leaf blade of ovate-lanceolate to obovate shape (vs. elliptic-oblong to ovate-lanceolate), smaller length-width ratio of 2.37 ± 0.31 (vs. 3.17 ± 0.32), slightly conduplicate (vs. not conduplicate), less lateral veins of 6–8 pairs (vs. 12–16 pairs), upper surface slightly rugose (vs. rugose), leaf margin plane (vs. revolute), lower surface densely grey tomentose (vs. grey tomentose, with bloom), greater corolla diameter of 7–9 mm (vs. 5–6 mm), styles 2 (vs. 2–3), pyrenes 2 (vs. 2–3), larger pollen grains P/E values of 2.05 ± 0.12 (vs. 1.19 ± 0.05) and leaf epidermis type W (vs. type I). Based on phylogenetic analysis of the whole chloroplast genome, C. densiflorus is sister to C. rhytidophyllus, but distantly related to C. salicifolius.

Diagnosis: Morphologically, Cotoneaster densiflorus is similar to C. salicifolius, but differs in its leaf blade of ovate-lanceolate to obovate shape (vs. elliptic-oblong to ovate-lanceolate), smaller length-width ratio of 2.37 ± 0.31 (vs. 3.17 ± 0.32), slightly conduplicate (vs. not conduplicate), fewer lateral veins of 6–8 pairs (vs. 12–16 pairs), upper surface slightly rugose (vs. rugose), leaf margin plane (vs. revolute), lower surface densely grey tomentose (vs. grey tomentose, with bloom), greater corolla diameter of 7–9 mm (vs. 5–6 mm), styles 2 (vs. 2–3) and pyrenes 2 (rarely 3). Although there is a closer phylogenetic relationship between the new species and C. rhytidophyllus, it is easy to distinguish them by the indumentum color of branchlets, leaves and inflorescences, rugose leaf upper surface, fruit shape and pyrenes number. See Table 2, Figs 1, 2 for a detailed comparison.

Etymology: The specific epithet refers to the compact compound corymbs with (5–)10– to 50–(61)-flowered per inflorescence.

 Abstract  

A new rainforest understorey tree, Fagraea christinae Y.W. Low & V.A. Albert (Gentianaceae), is described here based on three collections from the Bird's Head Peninsula, western New Guinea. The new species was previously included in the species complex F. ceilanica Thunb. s.l. Fagraea christinae is superficially similar to F. annulata Hiern and F. berteroana A. Gray ex Benth. in having stamens inserted upon a fleshy ring on the inner surface of the corolla tube, but differs from those two taxa in having crenate bracteoles and calyx lobes. The new species is provided with line drawings, field photographs and a distribution map.

 Researchgate.net/publication/359327717

 

Abstract

A new species of Hyphessobrycon presenting dimorphic males is described from the western Amazon basin in Brazil, Colombia, Ecuador, and Peru. The new species has been mistakenly identified in the literature with the non-congener Hemigrammus marginatus, with which shares a similar color pattern by presenting dark patches of dark pigmentation on caudal-fin lobes. It can be distinguished from the latter species, as well as from Hemigrammus durbinae, and two similar congeners, Hyphessobrycon diancistrus and Hy. otrynus, all of which sharing the same caudal fin color pattern, by the combination of presenting a dark patch of pigmentation on the dorsal fin, a single large anal-fin hook at the last unbranched anal-fin ray in mature males, and a moderately high body depth (22.4–32.5 % SL, mean 28.4 %). The new species is more similar to Hyphessobrycon diancistrus, which is putatively its closely related taxon. A putative close relationship with Hyphessobrycon otrynus, and with a non-congener presenting a distinct color pattern but sharing a similar sexual dimorphism on anal-fin hook morphology, Hemigrammus boesemani, is suggested.

Abstract

A revision of the ginger genus Geostachys (Zingiberaceae: Alpinioideae: Alpinieae) in Cambodia, Laos and Vietnam is presented. Three species are formally recognised, all endemic to the area of study, including one new species from central Vietnam. Lectotypes are designated for G. annamensis and G. pierreana. The uncertainty about the type locality of G. pierreana is highlighted; the absence of this species in Thailand and Vietnam is demonstrated. The presence of Geostachys in Laos is discussed. The key to the species of the genus is provided. For each species, description, notes on etymology/eponymy, distribution, IUCN preliminary assessment, habitat and phenology, and taxonomy are given. The newly described species, Geostachys aristata, is compared to the morphologically closest congener, G. annamensis, from which it differs by green leaf sheaths and ligules, greenish bracts and bracteoles with prominently aristate apices, prominently mucronate calyx lobes and labellum with crimson spots extending to the margins.

Abstract  

Woodworthia is a diverse genus of diplodactylid geckos found in Aotearoa/ New Zealand, with 17 likely species. Despite this diversity, only two species have been formally described: Woodworthia maculata (Gray, 1845) and W. chrysosiretica (Robb, 1980). In this paper, we use an integrated taxonomic approach to describe a new species of Woodworthia gecko, Woodworthia korowai sp. nov., found along the western coastline of the Auckland Region, New Zealand. Although this species occurs in duneland habitat behind a popular beach near New Zealand’s most populated city, it was only recognised as a distinct taxon in 2016. We describe W. korowai sp. nov. based on a suite of morphological character states and substantial genetic divergence, based on the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene, that distinguish it from W. maculata sensu stricto and all other known species of Woodworthia. Phylogenetic reconstruction and molecular dating place it sister to the W. maculata group, with an estimated time of divergence in the mid to late Pliocene. This gecko is one of the most geographically restricted of all Woodworthia geckos, occupying an area of less than 500 km2 within the Auckland Region. Its narrow range and coastal association make it susceptible to environmental and genetic stochasticity. Furthermore, the popularity and recreational usage of the dune system threaten its habitat. Therefore, we hope that this description will bring attention to the value of coastal environments and the unique and sensitive duneland of Te Korowai-o-Te-Tonga/ South Kaipara Peninsula and Te Oneone Rangatira/ Muriwai Beach in particular and encourage conservation efforts to protect this newly described species and its habitat.

Formerly known as the Muriwai gecko, this enigmatic species from the west coast of Auckland has just been formally described. They've been renamed the Korowai gecko (Woodworthia korowai) in reference to the south Kaipara peninsula where they live, and their colouration / striped pattern - which resembles the woven flax made into korowai (cloaks).

[Mollusca • 2022] Battle of the Bands: Systematics and Phylogeny of the white Goniobranchus nudibranchs with marginal bands (Nudibranchia: Chromodorididae)

Abstract

Species identities of Goniobranchus nudibranchs with white bodies and various marginal bands have long been problematic. In this study, specimens of these Goniobranchus nudibranchs from the Philippines, Peninsular Malaysia, Japan, Papua New Guinea, and Madagascar were analyzed and molecular data were obtained in order to re-examine the relationships between species within this “white Goniobranchus with marginal bands” group. The analyses clearly recovered six species groups corresponding to the described species Goniobranchus albonares, G. preciosus, G. rubrocornutus, G. sinensis, and G. verrieri as well as one new species, G. fabulus Soong & Gosliner, sp. nov. Notably, G. preciosus, G. sinensis, G. rubrocornutus, G. verrieri, and G. fabulus Soong & Gosliner, sp. nov. exhibit color variation and polymorphism, suggesting that some aspects of color patterns (e.g., presence or absence of dorsal spots) may not always be useful in the identification of species in the “white Goniobranchus with marginal bands” group, whereas other features such as gill and rhinophore colors and the arrangement and colors of the mantle marginal bands are more diagnostic for each species.

Abstract

A new species of Palaemonella, P. sandyi sp. nov., is described on the basis of specimens collected in association with euphylliid scleractinian corals, Euphyllia glabrescens and E. cristata. Material was collected from the Maldives, Cebu in the Philippines, Semporna in Malaysia, and from Java, Bali, Sulawesi, Kalimantan, Ternate and Raja Ampat in Indonesia. The new species is similar to P. colemani and P. euphyllius, which are associated with euphylliid corals of the genus Fimbriaphyllia. The new species can be distinguished from P. colemani and P. euphyllius, as well as from the species P. philippinensis and P. smiti, which are both symbionts with plerogyrid scleractinians, on the basis of morphological characters in the rostrum and ambulatory pereiopods, colouration, and molecular data.
