Two new species and new records of Otocepheidae (Acari, Oribatida) from Yunnan, Southwest China

This work includes taxonomic data on four species of oribatid mites of the family Otocepheidae from Yunnan, China. Two new species of the genera Basiceramerus and Eurostocepheus are described, respectively. Basiceramerus ovatussp. nov. differs from B. bangladeshensis Corpuz-Raros & Gruèzo, 2008 by the wavy marginalis passing the base of the adanal setae, prodorsal condyles well separated from median ones, a ventral ridge present, and the anal plate foveolate; it differs from B. igorotus Corpuz-Raros & Gruèzo, 2011 from Vietnam by the wavy marginalis passing the base of the adanal setae, a connected tutorium and lamelliform expansion, a ventral ridge present, a smooth genital plate, and seta an2 located close to the median margin of the anal opening; it differs from B. igorotus from the Philippines by the lamellar setae inserted behind the tip of the lamella, separated prodorsal condyles, lyrifissure im posterior to gla, genital plate smooth, anal plate foveolate, and the wavy marginalis passing the base of the adanal setae. Eurostocepheus (Eurostocepheus) sinutussp. nov. differs from other known species of this genus by having a ventral groove between the genital aperture and the ventral ridge, eight pairs of notogastral setae, and distinctly shorter and thinner notogastral setae p1, p2, p3, h3. Eurostocepheus (Eurostocepheus) aquilinus Aoki, 1965 and E. (E.) mahunkai Mondal & Kundu, 1999 are reported for the first time from China.

Functional Morphology and Characters of five abundant species of Ladybirds (Coleoptera: Coccinellidae)

Functional morphology of five coccinellid species, viz.Coccinella septempunctata, Coccinella transversalis, Menochilus sexmaculatus, Propylea dissecta, and Hippodamia variegata, of the Coccinellini tribe (Coleoptera: Coccinellidae). These ladybirds prevalent arise in the agricultural fields, hence could be efficiently spotted by their characteristic elytral pattern and spots. However, we have dissected male and female genitalia and found significant differences at the species level. In males, paramere and median lobe while stylus and genital plate in females are exploitable to differentiate species exhibited by line-drawings.

New subtribes of Arachnocephalini (Orthoptera: Mogoplistidae) and a new genus and species of this tribe from South Africa

The tribe Arachnocephalini is divided into three subtribes: [1] Pseudomogoplistina subtrib. nov. with one genus lacking ventrolateral lobes on the tarsi and having a massive Y-shaped sclerite in the male genitalia; [2] Bothromogoplistina subtrib. nov. including two genera with similar tarsi but with a different structure of the male genitalia (lacking a Y-shaped sclerite and having a long and thin virga-like sclerotised rachis inside a membranous invagination of the ventral fold); [3] Arachnocephalina Gorochov, 1984 possibly including all the other genera of this tribe (these genera are with a pair of ventrolateral lobes on the second tarsal segment and/or with the male genitalia more or less similar to those of Bothromogoplistina subtrib. nov.). One new genus with one new species (Bothromogoplistes paraproctalis gen. et sp. nov.) are described from a burrow in the arid territory of South Africa. This cricket is probably related to the genera Cycloptiloides Sjöstedt, 1910 and Eucycloptilum Chopard, 1936, but their males differ from each other in the pronotal length, the presence or absence of wings and tympana, and the shape of the paraprocts and genital plate. One species, Cycloptiloides parvum (Chopard, 1961), comb. nov., is transferred from Eucycloptilum to Cycloptiloides.

New species of the genus Phlugiolopsis from its subgenus Omkoiana stat. nov. (Orthoptera: Tettigoniidae: Meconematinae)

The genus Phlugiolopsis Zeuner, 1940 is considered: its brief comparison with some similar genera is given, and its subgeneric composition is discussed. This genus is tentatively subdivided into two subgenera: Phlugiolopsis s. str. with three possible species; the subgenus Omkoiana Sänger et Helfert, 2002, stat. nov. with all the other species of this genus including three “subgenera” with unclear status (Longiloba Bian et Shi, 2018; Tribranchis Bian et Shi, 2018; Uncinata Bian et Shi, 2018). Two new species, Ph. (O.) trilobulata sp. nov. with three lobes on the male cercus and Ph. (O.) bilobulata sp. nov. with two such lobes, are described from Vietnam and Indonesia, respectively; these species additionally differ from each other in the male genital plate with specialized apical hooks (Ph. trilobulata sp. nov.) or with a slightly bilobate apex (Ph. bilobulata sp. nov.). From the other congeners, these species are distinguished by the same characters as well as some other features connected mainly with shape of the male cercal lobes and of the female genital plate.

Taenionema (Plecoptera: Taeniopterygidae), a stonefly genus new to the fauna of China

The taeniopterygid genus Taenionema Banks, 1905 is reported from China for the first time. A newly discovered and probable new species of this genus, Taenionema sp., is described and illustrated based on larvae from Zhejiang Province of coastal southeastern China. The species is characterized by the male larva having a bilobed post-genital plate. Adults will be necessary for a future formal species description. This contribution represents the first larval description in the family Taeniopterygidae from China.

Two new species of Brazilian springtails (Hexapoda: Collembola) with comments on Neotropical Brachystomella Ågren and Seira (Lepidocyrtinus) Börner

Herein we describe two new species of Brazilian springtails, both from Rio Grande do Norte, Brazil. Brachystomella nordestina sp.n. resembles other Neotropical congeners with 8+8 eyes, postantennal organ with four lobes and 19/19/18 chaetae on tibiotarsi I–III, but it is unique in the combination of trilobed apical bulb, 2+2 dorsal chaetae on thorax I, male’s genital plate with 4+4 modified eugenital chaetae and 2+2 hr chaetae on lateral anal valves. Seira (Lepidocyrtinus) dapeste sp.n. is similar to other Neotropical species of Lepidocyrtinus Börner, 1903 in long antennae, mesonotum projected over head and presence of modified blunt macrochaetae on dorsal furca, but differs in the combination of dorsal head chaetotaxy, 14–19 a macrochaetae on thorax II, 7–9 central macrochaetae on thorax III and 4 central macrochaetae on abdomen II. We also present a detailed comparison and an updated key of the Neotropical species of Brachystomella Ågren, 1903.

Two new species of the family Nippobodidae (Acari, Oribatida), including a description of the leg-folding process

Nippobodespanemorfissp. n.andLeobodestrypasissp. n.are described by means of optical and Scanning Electron Microscopy (SEM) and compared to other congeners. The leg-folding process is described and illustrated.Nippobodespanemorfissp. n.is characterised by interlocking, double hook-shaped, posterior prodorsal condyle and anterior zone humeral apophysis; posterior prodorsal depression present. Tutorium a large lamina defining a pocket-shaped structure; bothridial opening ovoid, situated at the bottom of a U-shaped structure; deep, rounded-ovoid anterior notogastral depression present; ten pairs of notogastral setae;csetae looped, dentate, sharply tipped. Marginal setaeh3,p3on large promontories, followed by deep V-shaped incision; notogaster completely surrounded by circumgastric depression; lateral genital zone with locking structure constituted by longitudinal cuticular elevation, with promontories and a parallel furrow involved in the leg-folding process; genital plate smaller than anal plate.Leobodestrypasissp. n.is characterised by: the presence of posterior prodorsal depression and anterior notogastral depression; bridge-shaped anterior prodorsal condyles; heart-shaped frontal prodorsal orifice; ten pairs of notogastral setae; posterior prodorsal condyle and humeral condyle interlocked, forming double hook-like structure; circumgastric furrow surrounding entire notogaster; setaelp, h2, h1situated on shallow medial furrow; notogastral setaelm,lp,h1,h2medially aligned;p1, p2, p3, h3marginally situated. Legs I-IV, tutorium, pedotectum I, and pedotectum II involved in leg folding which is inferred to be a protection mechanism.
