[Botany • 2020] Impatiens quintadecimacopii (Balsaminaceae) • A New Species and A Newly Recorded Species of Impatiens from Yunnan, China

Impatiens quintadecimacopii G. W. Hu & Q. F. Wang, 

in Zhang, Peng, Tian, Hu & Wang, 2020. 

Impatiens quintadecimacopii G. W. Hu & Q. F. Wang sp. nov. is described and I. porrecta is reported as a new record from southwestern Yunnan province of China. These two species are close in morphology but can be distinguished by color of flowers, shape of lateral sepals and upper petals, and color of capsules. Morphological characters of these two species indicate they belong to sect. Uniflora in I. subg. Impatiens. Phylogenetic analysis of a combined dataset from nuclear ITS and plastid atpB-rbcL sequences confirmed their close relationship and their phylogenetic placement in sect. Uniflora.

Key words: Impatiens, New species, New record, Phylogeny, Taxonomy, China   

Impatiens quintadecimacopii G. W. Hu & Q. F. Wang sp. nov.

Etymology: The specific epithet "quintadecimacopii" is derived from the Fifteenth Meeting of the Conference of the Parties of the United Nations Convention on Biological Diversity (CBD COP15). This species is named for this upcoming conference which will be hold in Kunming, Yunnan, China in 2021.

[Botany • 2021] Cirsium taiwanense (Asteraceae) • A New Species of Cirsium (sect. Onotrophe, subsect. Australicirsium) from Taiwan

Cirsium taiwanense Y.H.Tseng & Chih Y.Chang, 

in Chang, Tzeng & Tseng, 2021.

A new species of CirsiumCirsium taiwanense Y.H.Tseng & Chih Y.Chang from central-northern Taiwan is reported in this article. This species is similar to C. hosokawae Kitam. in having a densely cobwebby abaxial leaf surface, but differs in its yellow (vs. vivid purplish red) corolla and the angle between the midrib and the lateral veins of the leaf, which is acute as opposed to nearly at a right angle in C. hosokawae. Cirsium taiwanense has 2n = 32 chromosomes, which is different from the other species in the Taiwanese subsect. Australicirsium Kitam. (2n = 34). An identification key to the Cirsium taxa of Taiwan is presented.

[PaleoAnthropology • 2021] Homo bodoensis • Resolving the “Muddle in the Middle”

Homo bodoensis 
Roksandic, Radović, Wu & Bae, 2021

Recent developments in the field of palaeoanthropology necessitate the suppression of two hominin taxa and the introduction of a new species of hominins to help resolve the current nebulous state of Middle Pleistocene (Chibanian) hominin taxonomy. In particular, the poorly defined and variably understood hominin taxa Homo heidelbergensis (both sensu stricto and sensu lato) and Homo rhodesiensis need to be abandoned as they fail to reflect the full range of hominin variability in the Middle Pleistocene. Instead, we propose: (1) introduction of a new taxon, Homo bodoensis sp. nov., as an early Middle Pleistocene ancestor of the Homo sapiens lineage, with a pan-African distribution that extends into the eastern Mediterranean (Southeast Europe and the Levant); (2) that many of the fossils from Western Europe (e.g. Sima de los Huesos) currently assigned to H. heidelbergensis s.s. be reassigned to Homo neanderthalensis to reflect the early appearance of Neanderthal derived traits in the Middle Pleistocene in the region; and (3) that the Middle Pleistocene Asian fossils, particularly from China, likely represent a different lineage altogether.

Suborder Anthropoidea Mivart 1864.

Superfamily Hominoidea Gray 1825.
Family Hominidae Gray 1825.

Tribe Hominini Gray 1825.

Genus Homo Linnaeus 1758.

Homo bodoensis sp. nov.

Etymology: The name bodoensis refers to the site of Bodo D'ar where the fossil specimen Bodo 1 was discovered.

Holotype: Bodo 1, a partial cranium of an adult (presumably male) individual, preserving the face and the anterior braincase, found in autumn 1976 by Alemayehu Asfaw, Paul Whitehead and other members of the Rift Valley Research Mission in Ethiopia headed by Jon Kalb.123, 124 The specimen is currently curated in the National Museum of Ethiopia in Addis Ababa, Ethiopia.  

Type locality: Bodo D'ar, the Middle Awash research area, Afar Depression, the northwestern part of the former Hararghe Province, Ethiopia.

Geological age and stratigraphic position: Upper Bodo Sand Unit.123 Dated to ca. 600 ka by laser-fusion 40Ar/39Ar technique (0.64 ± 0.03 Ma), biostratigraphy and tephrochronology.127

Archaeological context: The specimen is associated with an Acheulean stone tool assemblage.

Species diagnosis: The species is diagnosed by a unique combination of cranial traits. The Bodo specimen has already been described as showing a mix of H. erectus-like and H. sapiens-like features. The species is similar to H. erectus in having: a robustly built midface; total facial prognathism128; projecting tori and a flattened low frontal squama; sagittal keeling; a low vault profile; a prominent parietal angular torus; thick vault bones; no foramen lacerum is observable—it is presented as a narrow crevice.20, 128 These traits can be linked to the retention of the general cranial structure from H. erectus. Traits similar to other Middle Pleistocene and later hominin taxa include: increased cranial capacity and associated traits (broader frontal and mid-vault, reduced postorbital constriction, signs of parietal bossing, high and arched temporal squama), a vertical (rather than forward sloping) nasal margin, and the position of the incisive canal in front of the hard palate. Excessively thick and projecting, but segmented brow ridges, with the incipient division of the brow at mid-orbit and attenuated laterally may be considered a distinctive trait of the species.

[Ichthyology • 2021] Cetopsorhamdia hidalgoi • A New Species of Cetopsorhamdia (Siluriformes: Heptapteridae) from the Upper Amazon River Basin


Cetopsorhamdia hidalgoi
Faustino-Fuster & de Souza, 2021

A new species of Cetopsorhamdia is described from material collected on rapid inventories and ichthyological expeditions in the Amazon region of Peru, Ecuador and Colombia. The new species can be differentiated from all other species of Cetopsorhamdia by the colouration pattern on fins, number of vertebrae, number of ribs, level insertion of dorsal fin, number of rays on dorsal and pectoral fin, osteological characters and several other morphometric characters. The new species is distributed along tributaries of the upper Amazon River basin in Peru, Colombia and Ecuador.

Keywords: fresh water, Neotropical, taxonomy, three-barbel catfish

 (a) Lateral view, (b) dorsal view and (c) ventral view. Black arrow indicates the urogenital papillae.
Scale bar = 1 cm

Cetopsorhamdia hidalgoi new species

Etymology: Named in honour of the authors’ colleague and friend Max Hidalgo, professor, and curator of the Ichthyology Department at the Museo de Historia Natural in the Universidad Nacional Mayor de San Marcos (MUSM) for his devotion and dedication to Peru Ichthyology. Hidalgo collected the holotype, in addition to many specimens of the type series on expeditions including several rapid inventories in Peru that have led to the creation of multiple conservation areas.

 Geographic distribution: C. hidalgoi is known from the Ucayali, Marañón, Napo and Orteguaza rivers tributaries of the Upper Amazon River in Peru, Ecuador and Colombia and from the Madre de Dios River tributary of the Madeira River basin in Peru (Figure 6).

 Ecology: Found in clearwater streams with modest flow, substrate often with submerged leaves and sand.

[Herpetology • 2021] Amolops caelumnoctis Rao & Wilkinson, 2007, A Junior Synonym of Amolops splendissimus Orlov & Ho, 2007 (Anura: Ranidae)

 Amolops splendissimus Orlov & Ho, 2007

in Zhang, Rowley, Liu, ... et Yuan, 2021.
Amolops splendissimus Orlov and Ho, 2007 and A. caelumnoctis Rao and Wilkinson, 2007 were described almost simultaneously from either side of the China-Vietnam border. The two species share a strong morphological resemblance, and their taxonomic distinctiveness has been questioned, yet no one has confirmed the taxonomic relationship and status between the two taxa. To resolve this taxonomic issue, we collected additional topotypic and near-topotypic specimens of A. splendissimus and A. caelumnoctis from both China (A. caelumnoctis: Wenshan County, Yunnan Province; type locality Luchun County, Yunnan Province), and Vietnam (A. splendissimus: Tam Duong District, Lai Chau Province; type locality Mount Ky Quan San, Bat Xat, Lao Cai Province). Molecular analysis based on a 16S rRNA fragment revealed minimal genetic divergences between the two taxa (0.0%–0.4% uncorrected p-distance), and both species are closely related to A. viridimaculatus (2.1%–2.3%) and A. medogensis (3.5%–3.7%). Morphological comparisons between the newly collected specimens and the original descriptions of both species further support the lack of distinctiveness of the two species, hence, we conclude that A. caelumnoctis is a junior synonym of A. splendissimus.

[Herpetology • 2021] Rana wuyiensis • A New Species of the Genus Rana sensu lato Linnaeus, 1758 (Anura, Ranidae) from Wuyi Mountain, Fujian Province, China

Rana wuyiensis 
Wu, Shi, Zhang, Chen, Cai, Hoang, Wu & Wang, 2021
Wuyi Brown Frog | 武夷林蛙 || DOI: 10.3897/zookeys.1065.67005

A new species of the frog genus Rana sensu lato from Wuyi Mountain, Fujian Province, China is described. Molecular phylogenetic analyses clustered the new species into the R. johnsi group and indicated that it was genetically divergent from its closely related species. The new species could be distinguished from its congeners by a combination of the following characters: body size medium, SVL 41.4–45.6 mm (42.9 ± 1.9 mm, n = 4) in adult males and 47.6–50.3 mm (n = 2) in adult females; adult male with a pair of internal subgular vocal sacs; lateroventral grooves present on tip of toes; webbing on fourth toes reaching the tip of toe; transverse skin ridges distinctly present on the dorsal surface of thigh and tibia, the number large (mean 26.5 ± 2.7, range 22–29, n = 6); breeding males possess creamy white nuptial pad with tiny velvety spines on the dorsal surface of the first finger, divided into three parts.

Etymology: The specific name wuyiensis is in reference to the type locality, Wuyi Mountain, Fujian Province, China.
Suggested common name: Wuyi Brown Frog (in English), 
Wuyi Lin Wa (in Chinese; 武夷林蛙).

Distribution and ecology: Currently, Rana wuyiensis sp. nov. is known from Wuyishan National Park, Wuyishan City, Fujian Province, China. In our surveys from 2017 to 2021, the species was found only at one site. All individuals of the new species used in this work were collected from a stream and nearby grassland under the evergreen broad-leaf forest (Fig. 7). Six adult individuals and some very small tadpoles at early stages of development were found in the late August and early September. Only relative larger and middle-staged tadpoles were collected in the early November. This suggests that the breeding season of this species may begin in July or early August.
