Two new caeculid mite species, Andocaeculus beatrizrosso sp. nov. and Andocaeculus burmeisteri sp. nov., are described and A. weyrauchi (Franz, 1964) is redescribed based on material collected at the type locality. All post-larval stages are described for A. weyrauchi and Andocaeculus beatrizrosso sp. nov. and stochastic variation in the idiosomal and appendages chaetotaxy is considered. A clade of Andocaeculus containing the three species (the A. weyrauchi group) is established based on morphological characters, and confirmed with a Bayesian phylogenetic analysis of sequences from the CO1 marker. As result of the same analysis, the absence of the (st) pair of setae on leg II is proposed as a derived condition for the genus Andocaeculus, and the presence of the φ solenidion on leg IV is a derived condition for some Andocaeculus species of the A. weyrauchi species group.

The C.discoidalis species group of the genus Calleida Latreille from Asia (in the sense of Casale and Shi 2018) is revised with six species recognized. Four new species are described: C.piligera Shi & Casale, sp. n. (type locality: Taiwan: Siling, 24.65°N, 121.42°E); C.cochinchinae Casale & Shi, sp. n. (type locality: Vietnam: “Cochinchina”); C.yunnanensis Shi & Casale, sp. n. (type locality: Yunnan: Caiyanghe, 22.60°N, 101.12°E); and C.luzonensis Casale & Shi, sp. n. (type locality: Philippines: Nagtipunan, 16.22°N, 121.60°E). C.fukiensis Jedlička, 1963 is confirmed as an available and valid species name, and C. suensoni Kirschenhofer, 1986 is newly synonymized with it. A phylogenetic analysis of Oriental Calleida species, based on adult morphological characters, is performed. The results show that the monophyly of most species groups in Oriental Calleida is accepted, but the C.discoidalis group appears polyphyletic and comprises three lineages. However, because many species relationships in the cladogram lack significant supporting, presently the C.discoidalis group was remained to use for morphological convenience. Five types of female reproductive tracts were recognized, corresponding to five branches in the cladogram.

A key for the identification of all species of Microplinthus is given. A phylogenetic analysis based on morphological characters of the species referable to the genera Falsanchonus, Microniphades and Microplinthus was carried out, implementing Bayesian Inference and Maximum Parsimony. Results indicate that the genera Falsanchonus and Microniphades are paraphyletic and are here treated as junior synonyms of Microplinthus.

A new mite species, Holoparasitus rhombogynialis sp. nov. (Acari: Parasitidae) is described from Karavanke (Slovenia-Austria border). H. hemisphaericus (Vitzthum, 1923) is redescribed, including a description of the previously unknown male from the type locality in northern Austria. Both species are considered to be members of the Holoparasitus hemisphaericus species-group, which is newly defined. Ologamasus absoloni Willmann, 1940 is synonymised with H. hemisphaericus, and the female of H. intermedius (Holzmann) sensu Micherdziński is synonymised with H. cornutus Juvara-Bals & Witaliński.

The monophyly of the cosmopolitan tribe Halictini, including over 2300 currently recognized species, is supported by at least a single manifested synapomorphy shared by all members of the tribe: metasomal tergum VII of the male is modified; this forms a transverse ridge giving a false apex beneath which the tergum is strongly reflexed to the morphological posterior margin. On the basis of the present phylogenetic analysis, the tribe Halictini is subdivided into five subtribes: Halictina (comprised of 7 genera: Echthralictus, Glossodialictus, Halictus, Homalictus, Patellapis, Seladonia, and Thrincohalictus), Sphecodina (4 genera: Eupetersia, Microsphecodes, Ptilocleptis, and Sphecodes), Thrinchostomina (2 genera: Thrinchostoma and Parathrincostoma), Caenohalictina (9 genera: Agapostemon, Caenohalictus, Dinagapostemon, Habralictus, Mexalictus, Paragapostemon, Pseudagapostemon, Rhinetula, and Ruizantheda), and Gastrohalictina (one large and diverse genus: Lasioglossum s. l.). The subtribe Halictina is a paraphyletic group; the remaining four tribes are strictly monophyletic (holophyletic). The monophyly of the Halictus genus-group, comprising the genera Halictus and Seladonia, is supported by two distinct synapomorphies of the male genitalia: (1) dorsal gonostylus simple (not double), flattened, broad, narrowed proximally, and provided with a clump of very coarse bristles on the inner surface; (2) ventral gonostylus sclerotized, relatively thin and long, directed backward. Only generalized members of the group possess both the character states above. In derived members, the clump of bristles and the ventral gonostylus are often lost independently. The sister group of the Halictus genus-group is the genus Thrincohalictus. This is supported by the following synapomorphy found among the tribe Halictini only in Halictus, Seladonia, and Thrincohalictus: the ventral gonobasal rim in the male genitalia is forming a right posterolateral angle with a short projection directed laterally. Another feature characterizing these three genera is the presence (except in the parasitic subgenus Paraseladonia) of posterior bands of tomentum or dense and much plumose appressed hairs on the metasomal terga. However, this character is shared also with Patellapis subgenera Patellapis and Lomatalictus. The following subgeneric classification of the genera Halictus and Seladonia is suggested. The genus Halictus includes 12 subgenera: Acalcaripes (2 species), Argalictus (8), Halictus s. str. (4), Hexataenites (11), Lampralictus (1), Monilapis (29), Nealictus (2), Odontalictus (2), Platyhalictus (14), Protohalictus (13), Ramalictus (2), and Tytthalictus (4). The genus Seladonia comprises 6 subgenera, including 2 new ones: Mucoreohalictus subg. n. (15), Pachyceble (22), Paraseladonia (1), Placidohalictus subg. n. (5), Seladonia s. str. (36), and Vestitohalictus (16). The subgenera of Halictus and Seladonia are keyed. The phylogenetic tree of the subgenera of Halictus and Seladonia is reconstructed with use of 46 morphological characters of adults. All other genera of the tribe Halictini were taken as outgroup. The genus Halictus is ascertained as a strictly monophyletic group based upon a single postulated synapomorphy: dorsal gonostylus with a triangular hair patch as a distal appendage on inner side. All the subgenera of this genus appear as strictly monophyletic groups, with the exception of Monilapis, which is a paraphyletic one in relation to Acalcaripes. The monophyly of the genus Seladonia is supported by three synapomorphies, including a novelty (unique synapomorphy): male dorsal gonostylus with a deep cleft. All the subgenera of this genus are strictly monophyletic with the exception of Placidohalictus, which is a paraphyletic one in relation to Vestitohalictus and Mucoreohalictus. A synonymical catalogue of species and species-group names in the genera Halictus and Seladonia, including 442 names, is provided as an appendix.

We describe Simulium guaporense Py-Daniel adults and redescribe some morphological characters of its larvae and pupae based on specimens collected near the type locality in Rondônia State, Brazil. We report this species for the first time in Mato Grosso State. This species was placed originally in the S. siolii species group of the subgenus Psaroniocompsa; however, the thoracic pattern of the adults of S. guaporense is similar to that of species in the S. auristriatum species group. The immature stages were found on deciduous leaves and trailing vegetation in sandy-bottomed streams. Females were collected biting humans.

Two distinct new species of the ant genus Crematogaster, C. khmerensis sp. nov. and C. pfeifferi sp. nov., are described from Cambodia and Malaysia, respectively. The two species are unique among Asian Crematogaster in that they have vertically directed propodeal spines, but their systematic positions have not been determined based on morphological characters alone. Molecular phylogenetic analysis of 89 Crematogaster taxon matrices previously published plus C. khmerensis sp. nov., using nuclear genes, reveals that C. khmerensis sp. nov. is nested within the Australo-Asian Crematogaster clade. Morphological assignment of the developed pronotal shoulders implies a close relationship between C. khmerensis sp. nov. and the C. tetracantha-group. Based on molecular and morphological evidence, we erect a new species group, C. khmerensis-group, to contain C. khmerensis sp. nov. and C. pfeifferi sp. nov. Divergence time estimates using MCMCTree shows that the root node of the C. khmerensis sp. nov. terminal is estimated to be of middle Miocene age at 15 million years old. The position of the C. khmerensis-group well supports the Oriental- to Australian-region dispersal history that has been proposed for the Australo-Asian Crematogaster clade.

The molecular phylogeny of the subfamily Dolichopodinae (Diptera : Dolichopodidae) is reconstructed based on 79 species of 7 dolichopodine genera as ingroup, and 10 non-dolichopodine species from different genera as outgroup. A Bayesian analysis based on a mitochondrial DNA dataset consisting of 1702 characters (COI : 810; 12S : 366; 16S : 526) was carried out. Genital and non-genital morphological characters from a hitherto unpublished data matrix (based on 57 Dolichopodidae species) were used to explain and support the lineages hypothesised by our molecular phylogenetic analysis. The monophyly of the subfamily Dolichopodinae, and of the genera Dolichopus and Gymnopternus, was confirmed. The molecular analysis yielded nine species groups in Dolichopus that were proposed in previous studies using COI and Cyt-b. No evidence was found to support a clade including Dolichopus, Ethiromyia, and Gymnopternus. The genus Hercostomus proved polyphyletic with respect to Poecilobothrus, Sybistroma, and Gymnopternus. The following lineages were represented by strongly supported clades: Hercostomus germanus species group, H. vivax species group, H. nigrilamellatus species group, H. plagiatus species group, H. longiventris species group, H. fulvicaudis species group, and Poecilobothrus, Gymnopternus, Tachytrechus and Sybistroma (including Hercostomus nanus and H. parvilamellatus). Two clades that were previously established on the basis of morphology were confirmed in our phylogenetic analysis: (i) Poecilobothrus and the flower-feeding Hercostomus germanus species group, and (ii) the H. longiventris lineage and Sybistroma. In most cases, the groups identified in the molecular analysis could be supported and explained by morphological characters. Species of the Hercostomus germanus species group, Poecilobothrus, the Hercostomus longiventris species group, and a Sybistroma subclade have a similar microhabitat affinity.

Lachesilla is the most species-rich psocid genus, with 341 species grouped into 19 species groups (with at least 100 undescribed species), plus an additional undescribed species group. We present the first phylogenetic analysis of Lachesilla and a discussion on the relationships of sister genera of the subfamily Lachesillinae. We codified a matrix of 60 morphological characters (16 multistate and 44 binary) formed by 44 terminals: 37 ingroup species and seven outgroup species. A phylogenetic analysis was performed using Maximum Parsimony (MP) as optimality criterion, under equal weights and implied weights approaches. Monophyly of Lachesilla is not recovered, showing a polyphyletic genus divided in two major clades: clade A, composed of the pedicularia species group + Nadleria, and clade B, including the remaining species groups. The implied weights analysis produced a hypothesis with Hemicaecilius as sister group of clade B, nesting seven subclades mainly with low branch support values (symmetric resampling and bootstrap). These results suggest that all species groups, included in this analysis, can be considered monophyletic clades based on several synapomorphies, despite the andra species group was split up showing that L. punctata + L. dentata cluster together with high branch support values, but L. tehuautlensis and L. falcicula were recovered in different subclades.

Three distinct and independent molecular-based species delimitation analyses were performed among the species and populations included within theAustraloherosautranigroup, based on sequences of the mitochondrial gene Cytochrome b: a tree-based method proposed by Wiens and Penkrot (WP), a Character-based DNA Barcoding (CBB) and coalescent species delimitation method termed the Bayesian Implementation of the Poisson tree processes (bPTP). The congruence of WP and CBB delimited 11 independent lineages (species), while the bPTP delimited just nine lineages. We did not favour any of the methods, and we considered the possibility of two slightly variant scenarios. A time-calibrated phylogenetic analysis is proposed based on the predominant congruence of the results of these three species delimitation methods herein applied. The monophyly of theA.autranispecies group was highly supported with maximum node support value and diagnosed by 11 nucleotide substitutions. The sister clade of theA.autranispecies group is the clade comprisingA.sp. Timbé do Sul andA.minuano. The phylogenetic analysis supports three main clades within theA.autranispecies group, supported by maximum node support value, with the Southern Mata Atlântica clade as the most basal clade. Divergence time estimates indicate that the diversification of theAustraloherosoriginated during the early Neogene, but only in the late Neogene did the processes of diversification in the southeast and north regions occur. Diversification within theAustraloherosautranispecies group occurred synchronically for the three main clades during the beginning of the Quaternary. It is demonstrated that molecular characters are valuable tools for species recognition, particularly in speciose groups with inconspicuous or difficult to record morphological characters. The resulting phylogeny of theAustraloherosautranigroup is highly compatible with the geological and biogeographic scenarios proposed for the Neogene and Quarternary shaping of the extant river basins of eastern Brazil. Despite the origin of theA.autranigroup being dated to the late Miocene, species level diversification occurred in the Pleistocene and was probably driven by headwater capture events and sea-level fluctuations.

This revision focuses on the genus Calleida Latreille, 1824 (in the widest sense) in the Oriental Region, previously treated as genus or subgenus Callidiola Jeannel, 1949. In the present contribution, as first part of a series of revisions of the Asiatic Calleida species, we define nine species groups including all known Asiatic species, based on external features and morphological characters of male and female genitalia. A key for the identification of all nine species groups is provided, along with diagnostic characters, included species, geographical distribution, and brief discussion on monophyly and relationships for each species group. In particular, the present contribution deals with species of six small species groups, including eleven species in total, for which keys to all known species, descriptions, distribution maps, habitus images and genitalia illustrations are provided.Five new species are described: Calleida gressittiana Casale & Shi, sp. n. (type locality: Kinabalu, Sabah, Borneo), Calleida puncticollis Shi & Casale, sp. n. (type locality: Zigui, Hubei), Calleida jelineki Casale & Shi, sp. n. (type locality: Coimbatore, India), Calleida viet Casale & Shi, sp. n. (type locality: Vung Tau, Vietnam), Calleida borneensis Shi & Casale, sp. n. (type locality: Sabah, Borneo). Lectotypes for five taxa are designated. One synonymy is newly proposed: Calleida lieftincki Louwerens junior synonym of Calleida corporaali Andrewes, syn. nov.
