Contributions to the knowledge of Eylaoidea (Acari: Hydrachnidiae) from China

This paper enriches the taxonomic study of Eylaoidea Leach, 1816 from China. Eylais (Meteylais) hamata Koenike, 1897 is described to improve the taxonomy of adult Eylaidae Leach, 1816. Meanwhile, a new genus and a new species Pentachares sinensis Li & Guo gen. et sp. nov. is described and illustrated, which belongs to the subfamily Rhyncholimnocharinae Lundblad, 1936 in the family Limnocharidae Grube, 1859. The diagnosis of Rhyncholimnocharinae is modified. Rhyncholimnocharinae is first reported for Chinese fauna. A new key is provided for the subfamilies, genera and subgenera of Limnocharidae.

Biodiversity of orb-web spiders (family: araneidae) of buner valley, Pakistan

The present research was carried out to explore the spider fauna of Buner valley with taxonomic study from February 2018 to January 2019. For this purpose samples were collected, four times at each month from 4 tehsils: Daggar, Gagra, Mandan and Totalai. Two methods were used, hand picking and sweep net for collection of samples. During day and night, three habitats, arid area, agriculture land and building area were search for collection. A total of 534 samples of spider were collected from four sampling sites, in which 379 were belonging to family Araniedae. After confirmation, the identified species were belonging to 8 genera (Neoscona, Argiope, Cyclosa, Araneus, Cyrtophora, Larinia, Erivoxia and Poltys) and 19 species. 18 of them were identified to specie level while a single specie to its generic level. The genus Neoscona was the dominant genus 26.31% having 5 species while the genus Argiope 21.05% is the second dominant having 4 species followed by Cyclosa 15.78% having 3 species followed by Cyrtophora and Araneus 10.52% having two species both. The Poltys and Larinia 5.26% are the rarest genera represent single-single specie both. Statistical analysis show that specie richness (D) = 5.77, Simpson index (1-D) = 0.87, Shannon index (H) = 2.33. Diversity of spiders was evenly distributed and calculated Evenness value was H/InS = 0.5408. There is also few atypical species and Fisher alpha estimate high value (Fisher α) = 4.42. Chao-1 estimated we have reported 22 species.

A taxonomic study on the genus Ectopioglossa Perkins from Vietnam is presented. Two species, E. henseni Gusenleitner, 1990 and E. taiwana (Sonan, 1938), are recorded as new to the vespid fauna of Vietnam. A key to the Ectopioglossa species known from Vietnam is also provided based on external morphological characters.

A Phylogenetic and Taxonomic Study on Xylodon (Hymenochaetales): Focusing on Three New Xylodon Species from Southern China

Three wood-inhabiting fungal species, Xylodon laceratus, X. montanus, and X. tropicus spp. nov., were collected from southern China, here proposed as new taxa based on a combination of morphological features and molecular evidence. Xylodon laceratus is characterized by the resupinate basidiomata with grandinioid hymenophore having cracked hymenial surface, and ellipsoid basidiospores; X. montanus is characterized by the annual basidiomata having the hard, brittle hymenophore with cream hymenial surface, and ellipsoid to broadly ellipsoid basidiospores (3.9–5.3 × 3.2–4.3 µm); and X. tropicus is characterized by its grandinioid hymenophore with buff to a pale brown hymenial surface and subglobose basidiospores measuring 2–4.8 × 1.6–4 µm. Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis of the order Hymenochaetales indicated that the three new species clustered into the family Schizoporaceae, located in genus Xylodon; based on further analysis of ITS dataset, X. laceratus was a sister to X. heterocystidiatus; X. montanus closely grouped with X. subclavatus and X. xinpingensis with high support; while X. tropicus was retrieved as a sister to X. hastifer.

A Preliminary Taxonomic Study on the Flora of Rangpur District, Bangladesh

This study demonstrates that the vascular flora of the Rangpur district area consists of 825 species under 537 genera and 139 families. The pteridophytes and gymnosperms are represented by 25 and seven species, respectively, whereas the angiosperms by 793 species including 582 species of dicotyledons (Magnoliopsida) and 211 species of monocotyledons (Liliopsida). Poaceae with 67 species, representing 8.12% of the flora, is appeared as the largest family, and followed by Asteraceae, Fabaceae, Araceae, Malvaceae and Euphorbiaceae that collectively constitute 17.94% of this flora. Persicaria comprising 10 species is recorded as the largest genus, and followed by Ficus, Euphorbia, Solanum, Albizia and Brassica. About 59.71% taxa of this flora are herbs, 21.71% trees, 14.72% shrubs and the rest are palms, lianas, and bamboos. Erect herbs forming 35.22% of the flora comprise the most common life-form. In this flora, almost 64.29% taxa are native and the rest 35.71% are exotic. Nearly 62.61% taxa of the flora are found in wild, 26.90% as planted and 10.49% as cultivated. About 35.46% of the species commonly occur throughout all upazilas of this district. Most of the species are harboured in fallow lands, roadsides, gardens, and homesteads. All species of this district flora are known as economically useful. Most of its habitats and ecosystems are exposed to different threats. Adequate measures with effective management plans should be adopted and implemented for the sustainable use, improvement and conservation of this precious flora. Bangladesh J.

Comparative Morphology and Taxonomic Study of Chlorophytum sabiense And Two Other Species in the Genus Chlorophytum Ker-Gawl

Chlorophytum sabiense Omok. (a newly identified species in the family Asparagaceae) is unique, having multiple styles emerging from fused ovaries. This specialized character may be overlooked in conjuring up archetype for the genus Chlorophytum, since the genus is characterized by single and simple style. Comparative morphology and taxonomic study of Chlorophytum sabiense and two other species in the genus (Chlorophytum macrophyllum and C. stenopetalum) was carried out to appraise level of relatedness of Chlorophytum. sabiense and these existing members. Distribution of the three species is sympatric in the North Central part of Nigeria. Chlorophytum sabiense may be confused with either of the two species because of the attributes they have in common. Samples collected were raised in a garden and closely observed for duration of three years. Data collected from morphological studies were analyzed statistically. The three species show similarity in most of the vegetative characters studied, however Chlorophytum sabiense is distinguished from the two others having; multiple styles, smaller fruit size and shorter length of pistil relative to the stamen. Exceptional characteristics exhibited by Chlorophytum sabiense makes it stand out among species in the genus, while its close resemblance with its allies accounts for reason why it had escaped recognition for a long time.

Type specimens of P. jidanweishi, P. nigeri, P. qiqi, P. xiaoxiao, S. longtou and S. spinathoraxi are re-examined and photographed. All Asian Patu species are revised and two species, P. kishidai Shinkai, 2009 and P. bispina Lin, Pham & S. Li, 2009, are transferred to Crassignatha and proposed as new combinations: Crassignatha kishidaicomb. nov. and C. bispinacomb. nov. In addition, DNA barcodes and genetic distances of ten species treated in this paper were obtained to confirm identification.

Ostracods from the Pingyi Basin (Eastern China) and their significance on the K/Pg boundary

The Pingyi Basin is a late Mesozoic to Cenozoic fault basin in East China, containing a good record of Cretaceous to Paleogene non-marine carbonate and gypsum deposits. Abundant microfossils including gastropods, ostracods, charophytes and palynomorphs have been reported from this basin. A taxonomic study of ostracods from the Gejiazhuang section in the Pingyi Basin reveals a total of 17 species assigned to 11 genera. A further ostracod biostratigraphic correlation suggests the K/Pg boundary within Member 1 of the Bianqiao Formation in the Gejiazhuang section, which is supported by charophyte biostratigraphic results.
