Millettia lantsangensis Z.Wei was described within the tribe Millettieae on the basis of one fruiting and two flowering gatherings from Yunnan Province, China. Our critical examination shows that these gatherings are mixed and represent two distinct species from two different tribes. The fruiting specimens have woody branches, terminal infructescences and inflated pods, closely resembling Callerya sphaerosperma (Z. Wei) Z. Wei & Pedley from the same tribe, while the flowering collections have soft and herbaceous branches, axillary pseudoracemes and wart-like brachyblasts, and belong to Cruddasia insignis Prain from the tribe Phaseoleae. Because one of the flowering specimens was indicated as the type of Millettia lantsangensis, this is here reduced to a synonym of Cruddasia insignis. The genus Cruddasia Prain was previously reported only from Myanmar and Thailand, and is therefore a new genus record for the flora of China.

Perrottetia taronensis from the Dulong Jiang valley in northwestern Yunnan Province, China and the Babulongtan mountain range in northern Kachin State, Myanmar is here described as a new species of the Dipentodontaceae. It is the third species of the genus to be recognized for China and the first to be reported for Myanmar. It is similar to P. alpestriss.s. but differs by characters of its leaf margins, inflorescences, and fruit. The three subspecies of P. alpestris recognized by Hou in “Flora Malesiana” are here recognized as three distinct species, i.e., P. alpestris, P. moluccana, and P. philippinensis on the basis of differences in diagnostic characters and distribution. The report in the “Flora of China” of the Taiwan species P. arisanensis from Yunnan is determined to be incorrect due to misidentification of two specimens at KUN.

The powder post beetles (Coleoptera: Bostrichidae) (except Lyctinae) of Yunnan Province in Southwest China are reviewed for the first time. Keys to twenty-six genera and fifty-two species from the Yunnan region are provided. One new genus and seven new species are described: Dinoderus (Dinoderastes) hongheensis sp. nov., Dinoderus (Dinoderastes) nanxiheensis sp. nov., Gracilenta yingjiangensis gen. nov., sp. nov., Calonistes vittatus sp. nov., Calophagus colombiana sp. nov., Xylodrypta guochuanii sp. nov. and Xylodrypta zhenghei sp. nov.. Fourteen species are recorded in China for the first time. The bostrichid fauna of Yunnan is compared with those of the neighbouring bio-geographically related Southeast Asian and Himalayan regions. The fauna has a close affinity with that of tropical Southeast Asia and a much weaker relationship with the Palearctic region. The differences with the Himalayas may reflect the separate evolutionary and complex geological history of the two areas.

Craspedolobium schochii Harms was described in 1921 and has thin woody, flat, dehiscent pods with a narrow wing on the upper suture, which are quite different from those of other genera within the same tribe Millettieae (Fabaeceae), but its flowering materials from Laos and Thailand were described respectively as Millettia unijuga Gagnep. in 1913 and as Pueraria rigens Craib in 1927. Due to the priority of the Shenzhen Code, its correct name was accepted as Craspedolobium unijugum (Gagnep.) Z. Wei & Pedley as recently as 2010. The results of critical examination of specimens, literature and living plants in the wild showed that Spatholobus discolor C. F. Wei, a species described on the basis of one flowering collection from China, is also conspecific with C. unijugum. We therefore reduce S. discolor to the synonymy of C. unijugum herein. Additionally, we designated the second-step lectotype of the name C. schochii, and further found that Craspedolobium is a new genus record for the flora of Vietnam.

Morphological And Molecular Data

An investigation of the taxonomic status of Pareas hamptoni (Hampton's Slug snake) based on morphological and molecular data revealed a new distinct species from the Golden Triangle region (comprising parts of southern China, and adjacent Laos and Thailand). The new species is shown to be a sister species to P. hamptoni but can be separated from the latter by having 3–5 dorsal scale rows at midbody slightly keeled (vs 5–9 scales strongly keeled); a lower number of ventrals, 170–188 (vs 185–195); and a lower number of subcaudals, 67–91 (vs 91–99). The new species is currently known from northwestern Thailand, northern Laos, and the southern part of Yunnan Province in China at elevations of 1,160–2,280 m a.s.l. We suggest that the new species to be considered of Least Concern (LC) in the IUCN‘s Red List categories. Problems of taxonomy and actual distribution of the P. hamptoni complex are briefly discussed; our results show P. hamptoni is now reliably known only from Myanmar and Vietnam, but its occurrence in Yunnan Province of China is likely.

The Subject

One of the oldest fossil horseshoe crabs figured in the literature is Entomolithus lunatus Martin, 1809, a Carboniferous species included in his Petrificata Derbiensia. While the species has generally been included within the genus Belinurus Bronn, 1839, it was recently used as the type species of the new genus Parabelinurus Lamsdell, 2020. However, recent investigation as to the appropriate authority for Belinurus (see Lamsdell and Clapham, 2021) revealed that all the names in Petrificata Derbiensia were suppressed in Opinion 231 of the International Commission on Zoological Nomenclature (1954) for being consistently nonbinomial under Article 11.4 of the International Code of Zoological Nomenclature (ICZN) (International Commission on Zoological Nomenclature, 1999). Despite the validation of several species names for anthozoans, brachiopods, and cephalopods described in Petrificata Derbiensia in subsequent rulings (International Commission on Zoological Nomenclature, 1956a, b), Belinurus lunatus has not been the subject of any subsequent Commission ruling or opinion, and so its use in Petrificata Derbiensia remains suppressed. The Belinurus lunatus species name was used in several subsequent publications during the 1800s, none of which made the name available under ICZN article 11.5; Parkinson (1811) is also suppressed for being nonbinomial, while Woodward (1830), Buckland (1837), Bronn (1839), and Baily (1859) refer to the species only as a synonym of Belinurus trilobitoides (Buckland, 1837) through citation to the suppressed Pretificata Derbiensia. The first author to make Belinurus lunatus an available name was Baldwin (1905), who used the name in reference to a new figured specimen from Sparth Bottoms, Rochdale, UK, but again as an explicit junior synonym of Belinurus trilobitoides (Buckland, 1837). Therefore, it was not until Eller (1938) treated B. lunatus as a distinct species from B. trilobitoides that B. lunatus became an available name as per ICZN Article 11.6.1 under the authorship of Baldwin (1905) following ICZN Article 50.7.

A New Species

A new orchid species, Cymbidium jiangchengense, from Yunnan Province, China, is described and illustrated. Its distinctiveness is evaluated with morphology and molecular analyses. A detailed comparison between the newly discovered orchid and other members of Cymbidium was performed. The new plant was characterized by stem-like pseudobulbs, narrowly oblong leaves, coriaceous leaves with an acute apex, a 2-flowered inflorescence, a purplish pink flower, narrowly elliptic sepals, petals, a obovate-lanceolate lip with a cordate midlobe, a yellow central callus, and a disc with a trough shape longitudinal lamella from the base extending to the base of the midlobe and a lamellae apex inflated to form two calluses that are not confluent apically. These features distinguish this new orchid from all other known species of Cymbidium. A molecular study based on nuclear ribosomal ITS and plastid matK and rbcL DNA sequence data indicates that C. jiangchengense is a distinct species that sister to C. wadae and a member of section Eburnea, subgenus Cyperorchis.

The scleractinian family Lobophylliidae is undergoing a major taxonomic revision thanks to the combination of molecular and morphological data. In this study, we investigate the evolutionary relationships and the macro- and micromorphology of six nominal coral species belonging to two of the nine molecular clades of the Lobophylliidae, clades A and B, and of Symphyllia wilsoni, a lobophylliid species analyzed from a molecular point of view for the first time. Sequence data from mitochondrial DNA (COI and the intergenic spacer between COI and l-rRNA), and nuclear DNA (histone H3 and ITS region) are used to generate robust molecular phylogenies and a median-joining haplotype network. Molecular results are strongly in agreement with detailed observations of gross- and fine-scale morphology of skeletons, leading to the formal revision of the genera Micromussa and Homophyllia and the description of two newly discovered zooxanthellate shallow-water species, Micromussa pacifica sp. nov. Benzoni & Arrigoni and Micromussa indiana sp. nov. Benzoni & Arrigoni, and a new genus, Australophyllia gen. nov. Benzoni & Arrigoni. In particular, Acanthastrea lordhowensis and Montastraea multipunctata are moved into Micromussa, A. hillae is synonymized with A. bowerbanki and is transferred to Homophyllia, and a revised diagnosis for both genera is provided. Micromussa pacifica sp. nov. is described from the Gambier Islands with its distribution spanning New Caledonia and eastern Australia. Despite a superficial resemblance with Homophyllia australis, it has distinctive macroand micromorphological septal features. Micromussa indiana sp. nov., previously identified as M. amakusensis, is here described from the Gulf of Aden and the southern Red Sea as a distinct species that is genetically separated from M. amakusensis and is morphologically distinct from the latter due to its smaller corallite size and lower number of septa. Finally, molecular trees show that S. wilsoni is closely related, but molecularly separated from clades A and B, and, also based on a unique combination of corallite and sub-corallite characters, the species is moved into Australophyllia gen. nov. These findings confirm the need for using both genetic and morphological datasets for the ongoing taxonomic revision of scleractinian corals.

The genus Premna Linnaeus (1771: 587) contains about 200 species and is distributed in Old World tropics and subtropics with 46 species in China (Chen & Gilbert 1994). After being transferred from the Verbenaceae to the Lamiaceae, the genus becomes one of the biggest genera of the mint family (Harley et al. 2004), and now ranks among the more taxonomically difficult and complicated genera of Lamiaceae. Premna laevigata C. Y. Wu (1977: 440) was described from collections from Mengla County, Yunnan Province, China. However, the name was not validly published in the original description (Wu 1977) because three collections were simultaneously designated as types (i.e. H.T.Tsai 59-11098 was assigned as the flowering type, and S.J.Pei 59-11239 and, 59-13345 as fruiting types) which is contrary to articles 40.1 and 40.2 of the International Code of Nomenclature for Algae, Fungi and Plants (ICN) (McNeill et al. 2012). In the Catalogue of type specimens (Cormophyta) in the herbaria of China (Jin 1994), this name was validated by designating H. T. Tsai 59-11098 as the holotype. Unfortunately, it is still an illegitimate name according article 53.1 of the ICN because the name is a later homonym of P. laevigata Miquel (1858: 895), based on material from Indonesia (Sumatra). However this was not realised in either Flora Reipublicae Popularis Sinicae (Chen 1982), or in Flora of China (Chen & Gilbert 1994). After checking the type material of both names, it is concluded that the two homonyms apply to two totally unrelated taxa. Therefore, the Chinese species requires a new name which is proposed below.
