The monotypic genus Pseudobartsia Hong (1979: 406) is represented by Pseudobartsia glandulosa (Bentham) Yu & Li in Yu et al. (2015: 197) occurring in China and India (Yu et al. 2015, POWO 2020). In China, the species was collected in 1940 from Longtanying, Songming, Yunnan and since then this species was never collected or reported from these localities, hence it is believed to have gone extinct from here (Dong et al. 2013, Yu et al. 2015). In India, this species is known only by the type collection form Shivli, Uttarakhand in the year 1840 by Edgeworth (Khanna et al. 1999). Bentham (1846) described Euphrasia glandulosa based on specimens collected by Edgeworth in 1840 from Shivli, Uttarakhand, India. Later, Hooker (1884) made a combination for Euphrasia glandulosa Bentham (1846: 555) under the genus Phtheirospermum Bunge ex Fischer & Meyer (1835: 35). The genus Pseudobartsia was established by Hong (1979) with one species, Pseudobartsia yunnanensis Hong (1979: 406). Based on the study of the type specimens of Euphrasia glandulosa and Pseudobartsia yunnanensis, Tao (1993, 1996) found that Pseudobartsia yunnanensis cannot be distinguished from Phtheirospermum glandulosum (≡ Euphrasia glandulosa), therefore he treated Pseudobartsia as a synonym of Phtheirospermum and synonymized Pseudobartsia yunnanensis under Phtheirospermum glandulosum. However, recent phylogenetic studies (Dong et al. 2013; McNeal et al. 2013), pollen morphological evidence (Lu et al. 2007) and seed characters (Dong et al. 2013), support Pseudobartsia as distinct and independent genus. Because the name Euphrasia glandulosa as priority over Pseudobartsia yunnanensis, Yu & Li in Yu et al. (2015) made a new combination Pseudobartsia glandulosa to replace the latter in the genus Pseudobartsia.

Among Opiliones, Afrotropical lineages constitute some of the least studied groups in comparison with those endemic to other biogeographic provinces. Based upon morphological evidence, we erect Pyramidopidae, fam. nov. to distinguish a group of Laniatores from the family Phalangodidae. We review evidence from recent molecular phylogenetic studies that corroborate the independence of Pyramidopidae, fam. nov. from previously described families and support its sister relationship to another largely Afrotropical group, the family Assamiidae. The monotypic genus Maiorerus Rambla, 1993 is transferred to Pyramidopidae, fam. nov. The new family comprises 12 genera geographically restricted to Africa and the adjacent Canary Islands. Interfamilial relationships of the derived Laniatores are discussed in the context of gross and genitalic morphology.

Lappula sinaica was recently transferred to the monotypic genus Pseudolappula based on phylogenetic studies, while the related species, L. occultata, has remained in the genus Lappula. In this study, morphological, molecular, and palynological evidence supports that L. occultata should be transferred to the genus Pseudolappula. Both L. occultata and P. sinaica share a combination of nutlets features that distinguish them from Lappula: a longer adaxial keel and a linear attachment scar. Phylogenetic analysis based on ITS and trnL-F strongly supports L. occultata as the sister taxon of P. sinaica. In addition, pollen grains of these two species are 3-syncolporate with 3 alternating pseudocolpi, which is significantly different from the grains of Lappula taxa. Based on the above evidence, the new combination Pseudolappula occultata is proposed.

The generic name Udaria Gupta (1996:103) was established by Gupta (1996) with two fossil fungi species Udaria singhii Gupta (1996:103) and U. saxenae Gupta (1996:104) from Lower Tertiary sediments of Himachal Pradesh, India. Later on, Singh et al. (2018) described the new genus of liverworts, Udaria Singh, Majumdar & Singh (2018: 1537)   with the single species Udaria lamellicaulis Singh, Majumdar & Singh (2018: 1537) to the family Lophocoleaceae Vanden Berghen (1956: 208) from Arunachal Pradesh and Sikkim in Eastern Himalaya, India. After a thorough scrutiny of literature and type specimens, it was found that the liverwort genus name, Udaria Singh, Majumdar & Singh (2018: 1537) is illegitimate as it is a later homonym of the fossil fungi genus Udaria Gupta (1996:103). Therefore, a new replacement name Pandea U. B. Deshmukh is proposed with a new combination for the type species here in accordance with article 53.1 of Shenzhen Code (Turland et al. 2018).

The monotypic genus Bryomorphe Harv. is found to be homotypic with Klenzea lycopodioides Sch.Bip., which is considered to be a later synonym of Dolichothrix ericoides (Lam.) Hilliard & Burtt, and Bryomorphe is thus a synonym of Dolichothrix. The new genus Muscosomorphe J.C.Manning is proposed to accommodate the species previously included in Bryomorphe as B. aretioides (Turcz) Druce, along with the new combination M. aretioides (Turcz) J.C.Manning.

Microniphargus leruthi Schellenberg, 1934 (Amphipoda: Niphargidae) was first described based on samples collected in Belgium and placed in a monotypic genus within the family Niphargidae. However, some details of its morphology as well as recent phylogenetic studies suggest that Microniphargus may be more closely related to Pseudoniphargus (Amphipoda: Pseudoniphargidae) than to Niphargus. Moreover, M. leruthi ranges over 1,469 km from Ireland to Germany, which is striking since only a few niphargids have confirmed ranges in excess of 200 km. To find out the phylogenetic position of M. leruthi and check whether it may be a complex of cryptic species, we collected material from Ireland, England and Belgium then sequenced fragments of the mitochondrial cytochrome c oxidase subunit 1 gene as well as of the nuclear 28S ribosomal gene. Phylogenetic analyses of both markers confirm that Microniphargus is closer to Pseudoniphargus than to Niphargus, leading us to reallocate Microniphargus to Pseudoniphargidae. We also identify three congruent mito-nuclear lineages present respectively in Ireland, in both Belgium and England, and in England only (with the latter found in sympatry at one location), suggesting that M. leruthi is a complex of at least three species with a putative centre of origin in England.

Sematophyllum latifolium Brotherus (1911: 362), known only from the type collection, was originally described by Brotherus (1911) based on a collection made by C.C. Hosseus from Mt. Doi Suthep (Doi Sutäp), in northern Thailand. Pollawatn (2008) revised the family Sematophyllaceae s.l. in Thailand but did not see the type specimen of S. latifolium. During the study of Hosseus’s collections, however, we found two duplicates of type specimens of S. latifolium one located in H-BR and one in M. We found that several critical features of S. latifolium, such as the 1) irregular-pinnately branching habit with the erect flagelliform branches (Fig. 1A), 2) stem and branch leaves strongly differentiated (Fig. 1B−F), and 3) brotherelloid type alar cells often divided into larger hyaline cells towards leaf margins (Fig. 1G), were indistinguishable from those in the type material of Wijkia surcularis (Mitten 1859: 112) Crum (1971: 173), a common species found growing from India to Indochina (Gangulee 1980; Tan & Iwatsuki 1993; Tan & Jia 1999; Jia et al. 2005). Thus, we here propose S. latifolium as a new synonym of W. sucularis. In the protologue, Brotherus (1911) did not designate the holotype, therefore, it is necessary to select a lectotype for S. latifolium ((see Art. 9.11 of the Shenzhen Code (Turland et al. 2017)). We designate Hosseus’s collection (Hosseus s.n.) in H-BR (H) as the lectotype of the name S. latifolium.

Phylogenomic Study

Abstract— The generic classification of the Thelypteridaceae has been the subject of much controversy. Proposed taxonomic systems have varied from recognizing the approximately 1200 species in the family within the single genus Thelypteris, to systems favoring upwards of 30 genera. Insights on intrafamilial relationships, especially for neotropical taxa, have been gained from recent phylogenetic studies; however, in the most recent classification, 10 of 30 recognized genera are either non-monophyletic or untested. We sequenced 407 nuclear loci for 621 samples, representing all recognized genera and approximately half the known species diversity. These were analyzed using both maximum likelihood analysis of a concatenated matrix and multi-species coalescent methods. Our phylogenomic results, informed by recently published morphological evidence, provide the foundation for a generic classification which recircumscribed 14 genera and recognized seven new genera. The 37 monophyletic genera sampled demonstrate greater geographic coherence than previous taxonomic concepts suggested. Additionally, our results demonstrate that certain morphological characters, such as frond division, are evolutionarily labile and are thus inadequate for defining genera.

The Difference

There has been a long-standing taxonomic confusion over the name of a giant nereidid worm living in Asian intertidalmud flats. To clear up the confusion, we examined the type specimens of Paraleonnates uschakovi Khlebovich and Wu,1962 described from China as well as Periserrula leucophryna Paik, 1977 described from Korea (Polychaeta: Nereididae),together with additional non-type materials newly collected from Korea, China, Taiwan, and Thailand. Our results con-firmed that Periserrula leucophryna should be reduced to a junior synonym of Paraleonnates uschakovi as previouslynoted, and that this species is widely distributed in Asia, newly recorded from Taiwan and Thailand. We also present newinformation about the arrangement of three kinds of chaetae in the parapodia as a characteristic of this species. We alsocompared this species with Paraleonnates bolus (Hutchings and Reid, 1991) described from Australia and concluded thatthese are different species. Based on our examination, we propose the amended diagnosis of the genus ParaleonnatesKhlebovich and Wu, 1962. Paraleonnates Amoureux, 1985 erected as a monotypic genus for P. guadalupensis Amoureux,1985 was judged as a junior homonym of Paraleonnates Khlebovich and Wu, 1962, and P. guadalupensis is transferred to the genus Leonnates Kinberg, 1865.

Two genera of the shore-fly tribe Hyadinini, Hyadina Haliday and Parahyadina Tonnoir & Malloch, are revised, and all species treated, save P. lacustris Tonnoir & Malloch, are described for the first time. The phylogenetic position of both genera within Hyadinini is presented along with confirming, morphological evidence. The New Zealand fauna of Hyadina is now limited to the single new species H. breva, and Parahyadina is expanded from being a monotypic genus based on P. lacustris to also include the following 9 endemic new species: P. angusta, P. atra, P. bifurcata, P. bulla, P. debilis, P. edmistoni, P. hennigi, P. irwini, and P. latistylis. For both genera, emphasis is given to structures of the male terminalia, which are fully illustrated. Detailed locality data and distribution maps for all species are provided, and structures of the male terminalia are fully illustrated. For perspective and to facilitate recognition of genera, the tribe Hyadinini is diagnosed and a key to genera from New Zealand is provided.
