A species of the genus Panophrys (Anura, Megophryidae) from southeastern Guizhou Province, China

Abstract

Herein, we describe Panophrys congjiangensissp. nov. obtained from the Yueliangshan Nature Reserve, Congjiang County, Guizhou Province, China. Phylogenetic analyses based on the mitochondrial genes 16S rRNA and COI indicated that this new species represented an independent lineage, closely related to P. leishanensis. The uncorrected genetic distances between the new species and its closest congener, P. leishanensis, were 3.0% for 16S rRNA and 8.4% for COI. The new species is distinguished from its congeners by a combination of the following morphological characteristics (1) medium body size (SVL 28.6–33.4 mm in males and 38.4–40.2 mm in females); (2) a small horn-like tubercle at the edge of each upper eyelid; (3) the tympanum distinctly visible (TD/ED ratio 0.47–0.66); (4) vomerine teeth absent; (5) the tongue not notched behind; (6) a narrow and unobvious lateral fringe on toes; (7) relative finger lengths II < I < V < III; (8) rudimentary webs on toes; (9) hindlimbs slender, heels overlapping when thighs are positioned at right angles to the body; (10) two metacarpal tubercles on the palm, with the inner metatarsal tubercle long and oval-shaped; (11) the tibiotarsal articulation reaching the nostril when the leg is adpressed and stretched forward; (12) dorsal skin rough with numerous orange–red granules, ventral surface smooth; (13) a single internal subgular vocal sac present in males; and (14) in breeding males, weak gray-black nuptial pads with black nuptial spines present on the dorsal surface of the bases of the first and second fingers. To date, the new species is only known from the type locality.

Generic classification of Asian horned toads (Anura: Megophryidae: Megophryinae) and monograph of Chinese species

“…Remarks: In the original description of this species, the number of male paratypes was mentioned as “15 males” in the designation while the total number of males in the type series (holotype and paratypes) was mentioned as “ n =15” in Table 5 ( Luo et al, 2021 ), which is inconsistent. The correct number of male paratypes should be “14 males” as only 14 specimens were listed in the designation.…”

“…Remarks: The institute abbreviation of this species was provided as GNUG in the original description ( Zhang et al, 2017 ) but has been officially changed to GZNU ( Luo et al, 2021 ).…”

“…Navigating the intricate taxonomic history of Megophryinae, Boulenophrys has undergone several revisions despite being a relatively recent-established genus (Fei & Ye, 2016). It was frequently considered as a subgenus or synonymous of Megophrys, Panophrys, or Xenophrys (e.g., Chen et al, 2017;Luo et al, 2021;Lyu et al, 2021;Mahony et al, 2017) until Dubois et al (2021) recognized that the name Panophrys was preoccupied. They then reestablished Boulenophrys as the valid generic name following the International Code of Zoological Nomenclature.…”

Impatiens bijieensis (Balsaminaceae), a new species from karst plateau in Guizhou, China

“…In recent years, a few new species have also been found in the northern temperate regions of Europe, Russia and China, as well as North America ( Liao et al 2021 ). Currently, there are more than 349 species of Impatiens in China ( Yuan et al, in press ) which are distributed mainly in the southwest and northwest mountainous regions, especially in southwest Provinces (including Guizhou, Yunnan, Sichuan) ( Chen 2001 ; Chen et al 2007 ; Cai et al 2015 ; Kuang 2015 ; Tan et al 2015 ; Ding et al 2016 , 2017 ; Xia et al 2019 ; Gu et al 2021 ; Liao et al 2021 ; Peng et al 2021b ; Song et al 2021a , b , c ) and 61 species of Impatiens have been reported in Guizhou Province ( Xiong and Yang 2009 ; Cong 2010 ; Kuang et al 2014 ; Luo and Deng 2015 ; Peng et al 2021a ; Yu et al 2021 ; Yuan et al in press ).…”
