A New Species

We describe a new species of Tuber from Yunnan Province, China, based on molecular and morphological data. This species is characterized by its snow-white ascomata, pubescent peridia and subglobose or globose ascospores. Tuber sinoniveum sp. nov. is phylogenetically closely related to T. sinosphaerosporum but differs in having ascospores with more meshes (3–9 along) and glabrous peridia. Phylogenetic placement of this novel Tuber species is in the Puberulum group.

A New Species

Changnienia Chien (1935: 89) is a monotypic genus of tribe Calypsoeae endemic to eastern and central China (Chen et al. 1999, 2009, Freudenstein 2005), previously with only the species C. amoena Chien (1935: 90), which was listed in the Chinese Redbook in 1992 (Fu 1992). Yang & Zhu (1984) reported a chromosome number for it of 2n=46. Sun et al. (2006) observed pollination and found that Bombus trifasciatus was its pollinator. Zhai et al. (2013) confirmed the phylogenetic placement of this species as a member of tribe Calypsoeae (sensu Pridgeon et al. 2005). A new species of Changnienia is described and illustrated here based on molecular and morphological evidence. It is discovered in Malipo, Yunnan Province, China.

The genus Taczanowskia Keyserling, 1879 is one of the rarest groups of spiders in the orb-weaving family Araneidae, with only five species described and 17 specimens cited in publications. Our study provides new insights into the evolutionary relationships and diversity of Taczanowskia. Using morphological data, we tested the evolutionary relationships of the genus within the family Araneidae and propose the first phylogenetic hypothesis depicting the relationships among species of Taczanowskia. Our results place Taczanowskia as sister to Mastophora Holmberg, 1876, and confirm the monophyly of Taczanowskia. We describe the first species of Taczanowskia from Ecuador, collected at a Waorani community on the River Curaray basin, Amazonian lowlands of Ecuador. The new species can be easily diagnosed from all other species of Taczanowskia by having two tubercles in the opisthosoma; a distinct patchy dark–light colouration pattern with dark spots concentrated towards the anterior margin and on the lateral tips; small bundles of white setae forming a reticulum across the dorsal part of the opisthosoma, and the first two femora thick but lacking teeth on the margin.

A New Species

A new species of the genus Dendrelaphis is described from Xishuangbanna, southern Yunnan, China, based on molecular and morphological data. The new species can be differentiated from other congeners by the following combination of characters: 1) ground color of body bronze, a black postocular stripe extending onto the neck only; 2) pale and dark ventrolateral stripe absent; 3) relatively indistinct transverse bands on the anterior part of lateral body; 4) loreal single; 5) vertebral scales strongly enlarged; 6) dorsal scale rows 15-15-11, all smooth; 7) ventrals 193–197, subcaudals 130–135, paired; 8) SVL/TOL ratio 0.292–0.301; 9) supralabials 9, 4th through 6th touching the eye; 10) the outermost row of dorsal scales the same color as other dorsal scales; 11) retracted hemipenis extending to the 6–7th subcaudal scales. According to molecular and morphological data, D. ngansonensis likely belongs to the D. cyanochloris complex. We further discussed D. cyanochloris complex from Tibet, Yunnan and Hainan, China. A key to Chinese species of Dendrelaphis is provided.

Junewangia aquatica sp. nov., a new Acrodictys-like fungus was collected on submerged wood from freshwater habitats in Yunnan Province, China. J. aquatica is characterized by its flared conidiophores with percurrent proliferations, monoblastic, terminal or intercalary, cylindrical conidiogenous cells, and subglobose to broadly ellipsoidal conidia with transverse and oblique septa. A phylogenetic tree of Acrodictys-like species was inferred from multi-locus (SSU, ITS and LSU) sequences. A key to the species of Junewangia is provided.

A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

A New Species

Habenaria luquanensis from Yunnan Province is described and illustrated. This new species most closely resembles H. delavayi in having a basal leaf rosette, flowers with a concave and abaxially keeled dorsal sepal and linear petals. It is distinguished by herbaceous, loosely arranged rosette leaves (versus tightly adpressed to each other), a lip which is 3-lobed only to 1/3–1/4 from the base and has narrowly oblong lateral lobes (versus deeply 3-lobed nearly to the base with linear-cuneate lateral lobes). Another similar species is H. finetiana, but this species can be distinguished by its cauline leaves, longer floral bracts, petals forming a hood with the dorsal sepal, a lip which is 3-lobed only in the upper half and  rhombic, serrate lateral lobes, a spur which is nearly as long as the ovary, and central rostellum lobe not clearly visible.

A New Species

Meiogyne oligocarpa sp. nov. (Annonaceae) is described from Yunnan Province in Southwest China. It is easily distinguished from all previously described Meiogyne species by the possession of up to four carpels per flower, its bilobed, sparsely hairy stigma, biseriate ovules and cylindrical monocarps with a beaked apex. A phylogenetic analysis was conducted to confirm the placement of this new species within Meiogyne. Meiogyne oligocarpa represents the second species of Meiogyne in China: a key to the species of Meiogyne in China is provided to distinguish it from Meiogyne hainanensis. Paraffin sectioning was undertaken to study the anatomy of the corrugations on the inner petals of Meiogyne oligocarpa to verify whether they are glandular.
