Tigridiopalma longmenensis, a new species from Guangdong, China, is described. This species differs from its ally, T. magnifica, by the polychasium consisting of scorpioid cymes, hypanthium with carinas on angles, and longer stamens with a conspicuously white or pink spur at the connective base of anther. A diagnosis and a distribution map of the two species are also provided. The complete chloroplast genome of T. longmenensis was reported here. Phylogenetic analyses based on complete chloroplast genomes from T. longmenensis and other 15 Melastomataceae species indicated that T. longmenensis is sister to T. magnifica. The discovery of T. longmenensis terminates Tigridiopalma as a monotypic genus.

Dioscorea L., the largest genus of the family Dioscoreaceae with over 600 species, is not only an important food but also a medicinal plant. The identification and classification of Dioscorea L. is a rather difficult task. In this study, we sequenced five Dioscorea chloroplast genomes, and analyzed with four other chloroplast genomes of Dioscorea species from GenBank. The Dioscorea chloroplast genomes displayed the typical quadripartite structure of angiosperms, which consisted of a pair of inverted repeats separated by a large single-copy region, and a small single-copy region. The location and distribution of repeat sequences and microsatellites were determined, and the rapidly evolving chloroplast genome regions (trnK-trnQ, trnS-trnG, trnC-petN, trnE-trnT, petG-trnW-trnP, ndhF, trnL-rpl32, and ycf1) were detected. Phylogenetic relationships of Dioscorea inferred from chloroplast genomes obtained high support even in shortest internodes. Thus, chloroplast genome sequences provide potential molecular markers and genomic resources for phylogeny and species identification.

Compared with other members of the family Rosaceae, the chloroplast genomes ofFragariaspecies exhibit low variation, and this situation has limited phylogenetic analyses; thus, complete chloroplast genome sequencing ofFragariaspecies is needed. In this study, we sequenced the complete chloroplast genome ofF. × ananassa‘Benihoppe’ using the Illumina HiSeq 2500-PE150 platform and then performed a combination ofde novoassembly and reference-guided mapping of contigs to generate complete chloroplast genome sequences. The chloroplast genome exhibits a typical quadripartite structure with a pair of inverted repeats (IRs, 25,936 bp) separated by large (LSC, 85,531 bp) and small (SSC, 18,146 bp) single-copy (SC) regions. The length of theF. × ananassa‘Benihoppe’ chloroplast genome is 155,549 bp, representing the smallestFragariachloroplast genome observed to date. The genome encodes 112 unique genes, comprising 78 protein-coding genes, 30 tRNA genes and four rRNA genes. Comparative analysis of the overall nucleotide sequence identity among ten complete chloroplast genomes confirmed that for both coding and non-coding regions in Rosaceae, SC regions exhibit higher sequence variation than IRs. The Ka/Ks ratio of most genes was less than 1, suggesting that most genes are under purifying selection. Moreover, the mVISTA results also showed a high degree of conservation in genome structure, gene order and gene content inFragaria, particularly among three octoploid strawberries which wereF. × ananassa‘Benihoppe’,F.chiloensis(GP33) andF.virginiana(O477). However, when the sequences of the coding and non-coding regions ofF. × ananassa‘Benihoppe’ were compared in detail with those ofF.chiloensis(GP33) andF.virginiana(O477), a number of SNPs and InDels were revealed by MEGA 7. Six non-coding regions (trnK-matK,trnS-trnG,atpF-atpH,trnC-petN,trnT-psbDandtrnP-psaJ) with a percentage of variable sites greater than 1% and no less than five parsimony-informative sites were identified and may be useful for phylogenetic analysis of the genusFragaria.

In this paper we introduce a new species of Tamhinispora collected from Western Ghats of Maharashtra, India. This monotypic genus, belonging to Tubeufiaceae, was established based on the type species T. indica, collected from Tamhini Ghats of western India. The new species differs from the type species based on key characteristics, such as branched or Y-shaped conidial body and presence of arm-like conidial appendages. Single conidial cultures were developed and sporulation was established on MEA media following a long period of incubation. Phylogenetic analyses using ITS and LSU sequence data confirmed the position of T. srinivasanii along with T. indica in the Tamhinispora clade in Tubeufiaceae.

Fritillaria Cirrhosa

Fritillaria cirrhosa D. Don, whose bulb is used in a well-known traditional Chinese medicine to relieve cough and eliminate phlegm, is one of the most important medicinal plants of Fritillaria L. The species is widely distributed among the alpine regions in southwestern China and possesses complex morphological variations in different distributions. A series of newly related species were reported, based on obscure morphological differences. As a result, F. cirrhosa and its closely related species constitute a taxonomically complex group. However, it is difficult to accurately identify these species and reveal their phylogenetic relationships using traditional taxonomy. Molecular markers and gene fragments have been adopted but they are not able to afford sufficient phylogenetic resolution in the genus. Here, we report the complete chloroplast genome sequences of F. cirrhosa and its closely related species using next generation sequencing (NGS) technology. Eight plastid genomes ranged from 151,058 bp to 152,064 bp in length and consisted of 115 genes. Gene content, gene order, GC content, and IR/SC boundary structures were highly similar among these genomes. SSRs and five large repeat sequences were identified and the total number of them ranged from 73 to 79 and 63 to 75, respectively. Six highly divergent regions were successfully identified that could be used as potential genetic markers of Fritillaria. Phylogenetic analyses revealed that eight Fritillaria species were clustered into three clades with strong supports and F. cirrhosa was closely related to F. przewalskii and F. sinica. Overall, this study indicated that the complete chloroplast genome sequence was an efficient tool for identifying species in taxonomically complex groups and exploring their phylogenetic relationships.

A New Species

The family Oonopidae Simon, 1890 is composed of tiny spiders between 0.5 and 4mm (Baehr et al. 2012) that are distributed all over the world (Platnick et al. 2020; World Spider Catalog 2021). They occupy diverse habitats, mainly in tropical and subtropical regions (Platnick et al. 2020), generally associated with the soil and litter fauna (Ranasinghe & Benjamin 2018). Oonopidae is among the eight most diverse spider families with 114 genera and 1872 species (World Spider Catalog 2021). Most of this diversity was discovered after 2006, as a result of the Planetary Biodiversity Inventory (PBI) project: Goblin Spider (Platnick et al. 2012). Recent molecular phylogenetic analyses recovered Oonopidae as monophyletic (Wheeler et al. 2017), hypothesis supported by the presence of a synapomorphic pair of completely fused testicles (Burger & Michalik 2010). Brazil has a great diversity of Oonopidae (e.g., Brescovit et al. 2012a; Platnick et al. 2013; Feitosa et al. 2017), including the genus Predatoroonops Brescovit, Rheims & Ott 2012, endemic to the Atlantic Forest, that includes 17 species (World Spider Catalog 2021). The genus can be recognized by the male chelicerae frontally modified, with one or two pairs of distally sclerotized, and sometimes branched, apophyses, and by the pars cephalica dorsally squared (Brescovit et al. 2012b). In this paper, we describe a new species of the genus, based on a male specimen from the State of Minas Gerais: Predatoroonops stani sp. nov.. Also, we give new records for Predatoroonops yautja Brescovit, Rheims & Santos, 2012 from the same state and a distribution map with all the records of Predatoroonops along the Atlantic Forest.

Macrosolen plants are parasitic shrubs, several of which are important medicinal plants, that are used as folk medicine in some provinces of China. However, reports on Macrosolen are limited. In this study, the complete chloroplast genome sequences of Macrosolen cochinchinensis, Macrosolen tricolor and Macrosolen bibracteolatus are reported. The chloroplast genomes were sequenced by Illumina HiSeq X. The length of the chloroplast genomes ranged from 129,570 bp (M. cochinchinensis) to 126,621 bp (M. tricolor), with a total of 113 genes, including 35 tRNA, eight rRNA, 68 protein-coding genes, and two pseudogenes (ycf1 and rpl2). The simple sequence repeats are mainly comprised of A/T mononucleotide repeats. Comparative genome analyses of the three species detected the most divergent regions in the non-coding spacers. Phylogenetic analyses using maximum parsimony and maximum likelihood strongly supported the idea that Loranthaceae and Viscaceae are monophyletic clades. The data obtained in this study are beneficial for further investigations of Macrosolen in respect to evolution and molecular identification.

The monotypic genus Stegodera Martens, 1876 is systematically revised based on anatomical and morphological examination of freshly collected specimens. A new species from southern Hunan, which resembles Stegodera angusticollis, is confirmed to represent a new genus evidenced by comparative shell morphology and anatomy as well as by molecular phylogenetic analyses. The new genus might be more closely related to Stegodera and Nesiohelix Kuroda & Emura, but differs anatomically from the latter two genera by the absence of a dart apparatus.
