Mite Genus

We describe two new species of false spider mite in a new genus, Acaricis gen. nov., collected from native Australian sedges (Cyperaceae). The new genus shares morphological characters with the genera Tenuipalpus Donnadieu and Prolixus Beard, Fan & Walter. All three genera have dorsal opisthosomal seta h2 long and attenuate. Acaricis shares the presence of a rostral shield with Tenuipalpus; and shares with Prolixus an elongate body shape, absence of dorsal seta c1, genua I with two setae, nude genua IV, and setae g1 being inserted anterior to g2. Acaricis differs from both genera in having four palpal segments, as opposed to one to three.

Pseudosynaleurodicus gen. n. is described with two new species, P. mayoi sp. n. and P. nigrimarginatus sp. n. These new taxa have some exceptional morphological characters, including emarginate bulla-like terminal tarsal segments, two segmented legs, and features of the vasiform orifice. Placement of these taxa in the Aleurodicinae is tentative given some of their extraordinary morphological characters.

Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).

Abstract The phylogenetic study of the deep-sea genus Bentheogennema is based on four molecular markers and 79 morphological characters. All four previously recognized species and two new species of Bentheogennema, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. We have examined and coded six major groups of morphological characters related to the carapace (three characters), the pleon and the telson (14), the mouthparts (nine), the armature of the pereopods (five), the thelycum (27) and the petasma (21). Results of morphological and molecular analyses were similar. Two species were transferred from Bentheogennema to other genera (for one of them a new genus was erected) and two new species of Bentheogennema were described. Three pelagic genera (Gennadas, Bentheogennema and a new genus) created a robust clade. The divergence of this clade is linked to ‘smoothening’ of the body (reduction of the branchiostegal spine on the carapace, reduction and loss of the dorsolateral spines and the end-piece on the telson) and elaboration of the copulatory structures. We provide amended diagnoses of these three pelagic genera and key to species of Bentheogennema.

Five species of the family Odiidae (Amphipoda), including four new species, are recorded from Japan: Metodius cyanomaculatus sp. nov.; M. leucomaculatus sp. nov.; Postodius albifacies sp. nov.; P. sanguineus sp. nov.; and Antarctodius japonicus Ariyama, 2011. Morphological characters and coloration of these species are described in detail. Metodius gen. nov. is established for the two new species and is characterized by the very short and bare palp of the maxilla 1 and the large gnathopod 2 propodus. Keys to the odiid genera and the Postodius species in the world are provided. The genera can be distinguished from one another by the shapes of maxilla 1, maxilliped, pereopod 7, and telson. The Postodius species differs in the shapes of gnathopod 2, and pereopods 3, 7. Female of A. japonicus is firstly recorded. In this species, the presence of an accessory flagellum and a gill on the coxa 7 is confirmed.

AbstractA new Uropodina genus (Sinharaja gen. n.) is described on the basis of two new species (S. ceylonensis sp. n. and S. sinhala sp. n.) from Sri Lanka. The new genus differs by the strongly sclerotised dorsal lines, pentagonal pygidial shield, the shape and length of dorsal setae and the shape of first and fourth hypstomal setae, internal malae and epistome from the other known Uropodina genera.

The Linotetranidae (Acari : Tetranychoidea) is a poorly known group of cryptic false spider mites associated with grasses and sedges. We review the family at the world level, provide the first phylogenetic analysis of the family, and describe the first Australian representatives: Austrolinus, gen. nov. and two new species: A.��arenulus and A. kinnearae. Linotetranidae is redefined, and keys are provided for the families of the Tetranychoidea, and for all described genera and species of Linotetranidae.

A New Species

Mimarachnidae is an extinct planthopper family of the superfamily Fulgoroidea, with ten genera from the Cretaceous of Eurasia. Here, we describe a new genus, Cretodorus gen. nov. and two new species, Cretodorus granulatus sp. nov. and C. angustus sp. nov., on the basis of four specimens from the mid-Cretaceous amber of northern Myanmar. This remarkable genus can be separated from all other mimarachnids as follows: moderately elongate head, anteriorly protruded pronotum with straight lateral carinae, and unbranched MP of tegmen. Additionally, a new species of Burmissus Shcherbakov, 2017, Burmissus latimaculatus sp. nov., is described from the same Burmese amber, and the morphological characters of Burmissus szwedoi Luo, Jiang, Wang & Xiao, 2020 are supplemented for pronotum, clypeus, rostrum, and legs. These new discoveries enrich the palaeodiversity of mimarachnid planthoppers to fifteen species, ten of which are described from the mid-Cretaceous Burmese amber, suggesting that this extinct family remained highly diverse during this period.

These new taxa have some exceptional morphological characters, especially the strong protuberance on the last pair of legs in male. Both species are described based on both male and female specimens.
