The first extant representatives of the pseudoscorpion family Feaellidae from Southeast Asia are described. Cybella n. gen. is proposed for Cybella deharvengi n. sp. (type species), collected from an isolated limestone hill in Hon Chong Province, Vietnam, and C. bedosae n. sp., found in a limestone cave in Kampuchea, Cambodia. Cybella species seem to be restricted to karst formations and are probably troglophilic. The type localities of the two known species are threatened by quarrying activities, these being particularly pressing in the case of C. deharvengi n. sp. Cybella shows important differences from other Feaellidae that require a modification of the familial diagnosis and justify the erection of a new subfamily, Cybellinae. The discovery of this group provides insights into the evolution of the unusual morphology of the family, notably concerning the pleural plates of Feaellinae, which are lacking in Cybellinae. The smaller sclerites of the pleura of Pseudogarypidae and Feaellidae are shown to be muscle apodemes, which provide an additional synapomorphy for Feaelloidea. Two types of coxal spines, termed primary and secondary, are distinguished in Feaelloidea, based on the presence of a lumen within the primary spines and its absence in secondary spines. The new morphological term atrial plate is proposed for a sclerotized plate of the male genitalia, extending between the lateral rods and the lateral apodemes. Claims that the internal genital setae of males of non-chthonioid pseudoscorpions are secretory are reviewed and found to lack support.        Additional information concerning the fossil genus Protofeaella Henderickx, 2016 is provided, based on an adult male in amber from the Cretaceous (lowermost Cenomanian) of Myanmar. Protofeaella shares with Cybella the absence of pleural plates and the antiaxial position of the chemosensory setae of the movable chelal finger. However, it differs from both Cybellinae and Feaellinae in having relatively long chelal fingers that lack a tuberculate basal tooth, both of which are interpreted as symplesiomorphic states within Feaellidae. Protofeaella is therefore provisionally treated as a stem-group feaellid and not assigned to a subfamily.        The existence of a Cretaceous member of the Pseudogarypidae is noted in the mid-Cretaceous (late Albian‒early Cenomanian) of Germany, representing the oldest record of this family.

Fossil Genus

Three new fossil species from Burmese amber are described, one clearly in family Calamoceratidae, the other two in the highly variable family Odontoceridae. The family Odontoceridae contains 18 disparate genera, but there are no good diagnostic characters, which makes it difficult to place fossil taxa in this family. We here offer a revised diagnosis for the family, highlighting the lack of good diagnostic characters, and the need to use sets of characters to place (extinct) taxa in this family. On this taxonomic basis we describe two new species in the hitherto monotypic fossil genus Palaeopsilotreta Wichard & Wang, 2017 (Odontoceridae), Palaeopsilotreta burmanica sp. nov. and P. cretacea sp. nov., redescribe the type species based on additional information, and describe features of the female, based on two specimens, one of which is embedded adjacent to a male identified as P. xiai. Males of Palaeopsilotreta bear bipectinate antennae; the antennae of the females are simple and filiform. Similarly, bipectinate antennae are present in the third species we describe, Bipectinata orientalis gen. et sp. nov., which otherwise lacks the character combinations associated with the Odontoceridae, but clearly can be assigned to the family Calamoceratidae.

Two New Species

The Australian species of the small heterogastrid genus Parathyginus Scudder, 1957 have been reviewed, resulting in the establishment of the junior subjective synonymy of P. doddi (Distant, 1918) with P. signifer (Walker, 1872), and the description of two new species, P. australis sp. nov. and P. acuminatus sp. nov. A redescription of the genus is provided with emphasis on male and female genitalia characters, along with a key to all included Australian species. Male genitalia, particularly the details of the aedeagus, have been rarely studied in this genus or for that matter the family Heterogastridae particularly due to the difficulty in inflating the inflatable sections. In this study, therefore, an attempt was made to fully inflate and describe the aedeagus of all the species included in this contribution, as well as of Heterogaster urticae (Fabricius, 1775), the type species of the oldest genus Heterogaster Schilling, 1829, of the family Heterogastridae.

An overview of the taxa of Rhinorhynchinae (Nemonychidae) is presented. A phylogenetic analysis of the 19 extant genera of the Rhinorhynchinae and one fossil genus from the Lower Cretaceous (Cratomacer Zherikhin & Gratshev), based on 29 characters of adults, larvae and host plant associations, shows three monophyletic groups, treated as tribes (Rhinorhynchini, Mecomacerini and Rhynchitomacerini). Primitive associations are unknown for Rhinorhynchinae and early host use diversification included associations with Ranunculaceae (Nemonyx Redtenbacher), Pinaceae (Cimberis Gozis), Nothofagaceae (Rhynchitomacerini) and Podocarpaceae (Rhinorhynchini). While Mecomacerini diversified on Araucariaceae, within Rhinorhynchini there was a single reversal to Araucariaceae and a shift in Atopomacer Kuschel to Pinaceae. Placement of Cratomacer into Mecomacerini is consistent with geological and molecular data that suggest gymnosperms may have been the primitive hosts for the family. Three new genera are described in Rhinorhynchinae: Araucomacer, gen. nov. (type species A. hirticeps Kuschel) from Chile, Idiomacer, gen. nov. (type species I. basicornis, sp. nov.) from New Caledonia, and Zimmiellus, gen. nov. (type species Z. fronto, sp. nov.) from Queensland, Australia, while Stenomacer Kuschel, stat. nov. from Chile is reinstated from synonymy. Seven species are described as new: Atopomacer grandifurca, sp. nov. from Costa Rica and Panama, A. obrieni, sp. nov. from Mexico, A. panamensis, sp. nov. from Panama, A. pini, sp. nov. from Mexico, A. podocarpi, sp. nov. from Venezuela, Basiliogeus dracrycarpi, sp. nov. from western New Guinea and B. inops, sp. nov. from Queensland. Rhynchitomacer rufus Kuschel is a new junior subjective synonym of R. nigritus Kuschel, syn. nov., R. viridulus Kuschel is a new junior subjective synonym of R. flavus Voss, syn. nov. and Stenomacer fuscus Kuschel is a new junior subjective synonym of S. vernus Kuschel, syn. nov. Keys to genera of Rhinorhynchinae and to species of Atopomacer, Rhynchitomacer and Stenomacer are included. Diagnoses of the three extant subfamilies of Nemonychidae are included.

New Subgenus

Barraud (1934) described very briefly genus Heizmannia Ludlow as consisting of nine species including Heizmannia (Heizmannia) chandi Edwards. Most of the characters used in describing the species emphasized the male genitalia, based on which a diagnostic and illustrated key of adults was constructed of these nine species. Subsequently, however, the genus Heizmannia was extensively revised by Mattingly (1957, 1970) and Thurman (1959) from Southeast Asia. They included 20 species by introducing one new subgenus Mattinglyia. However, in Mattingly’s review (1970) Heizmannia (Heizmannia) chandi and Hz. (Mattinglyia) discrepans Edwards were not included. Tewari et al.(1986) re-described Hz. (Mat.) discrepans but Hz. chandi remained poorly described. In the present paper we are re-describing the adult male and female of Hz. (Hez.) chandi in detail, with emphasis on the male genitalia and variations observed in comparison to the original description of Barraud (1934).

AbstractRelationships of the genera included in the family Diastatidae by Duda (1934) are considered and their position in the Drosophiloidea is assessed. A family Campichoetidae is recognised following Griffiths (1972) for Campichoeta Macquart and the inclusion of Euthychaeta Loew and the fossil genus Pareuthychaeta Hennig in that family is confirmed. Contrary to Griffiths (op. cit.), however, the family Diastatidae is retained for Diastata Meigen alone, because of its many differences from the Ephydridae and Risidae to which it is allied. Euthychaeta spectabilis Loew is redescribed and characterised; a lectotype is designated; male and female genital structure is figured. For Campichoeta Macquart the five European species are keyed and new distribution data provided; male genitalia are figured and a lectotype is designated for C. punctum (Meigen). The Palaearctic and Nepalese species of Diastata are revised; 19 species are recognised - 11 of them described as new: 9 European species include nebulosa (Fallén), fuscula (Fallén), costata Meigen, adusta Meigen, ornata Meigen, vagans Loew, cervinala sp.n., boreonigra sp.n. and flavicosta sp.n.; 1 from the Far East, ussurica Duda and 9 from Nepal, basdeni Okada, okadai sp.n., macula sp.n., lugubris sp.n.,flavipes sp.n., mirabilis sp.n., rustica sp.n., hirsuta sp.n. and dolorosa sp.n. D. ornata is raised from synonymy while D. unipunctata Zetterstedt is placed in synonymy under adusta Meigen, modesta Melander under costata Meigen, fulvifrons Haliday and inornata Loew under fuscula (Fallén). Male genitalia are figured for all species, female ovipositors for 13 species. Available type material of Diastata has been examined and lectotypes have been designated where applicable: nebulosa (Fallén), fuscula (Fallén), costata Meigen, fulvifrons Haliday, vagans Loew, inornata Loew, unipunctata Zetterstedt and excluded from Diastata - anus Meigen, díadema Meigen and gracilipes Meigen. All names of Palaearctic species proposed in Diastata are discussed; 12 names do not belong to either family but only 4 of them can be positively identified, i.e. anus Meigen = Curtonotum anus (Meigen) (Curtonotidae); leucopeza Meigen and diadema Meigen both = Aulacigaster leucopeza (Meigen) (Aulacigastridae); gracilipes Meigen = Campsicnemus species, probably picticornis Zetterstedt (Dolichopodidae).

A new genus, Euryburnia gen. nov. (type species: Megamelus magnifrons Crawford, 1914) is erected to accommodate the group of Nearctic species of the family Delphacidae erroneously placed by Hamilton (2002) in the genus Eurybregma Scott, 1875. The new genus differs from Eurybregma by narrower metope without intermediate carinae on eumetope (only median carina is developed). According to male genitalia structure the new genus is close to the genera Unkanodes Fennah, 1956 and Chilodelphax Vilbaste, 1968, but distinguished by angular (not rounded) latero-ventral lobes of pygofer and by pygofer phragme without teeth and processes. From the genus Eurybregma the new genus differs by the presence of latero-ventral lobes of male pygofer. According to presence of unique, well developed beak-shaped basal lobes of dorso-lateral plates of ovipositor (first valvifers) the new genus is distinguished within all Delphacidae. New combinations proposed: Euryburnia magnifrons (Crawford, 1914), comb. nov. (=Megamelus magnifrons Crowford, 1914), Euryburnia montana (Beamer, 1952), comb. nov., (=Eurysa montana Beamer, 1952), Euryburnia obesa (Beamer, 1952), comb. nov. (=Eurysaobesa Beamer, 1952), Euryburnia eurytion (Hamilton, 2002), comb. nov. (=Eurybregma eurytion Hamilton, 2002).

AbstractIn Lepidoptera wing reduction is usually restricted to the females. We report a rare case of male brachyptery in the genus Xenomigia Warren, 1906 (Notodontidae: Dioptinae) from the high Andes of Venezuela. At the same time this is the first case of wing reduction in the family Notodontidae (Noctuoidea). The new species Xenomigia brachyptera sp. n. is described and the adult, male genitalia and other structures of the adult morphology are illustrated. Some aspects of wing reduction in Lepidoptera are discussed.

A set of 127 binary and multistate characters, weighted by the number of derived character states, degree of covariation, and level of homoplasy, was used in a cladistic analysis of type species representing 12 genera previously assigned to families Monticuliporidae and Mesotrypidae. The most parsimonious tree consisted of a 10-genus monophyletic crown group with the remaining two genera forming a basal paraphyletic stem group. The composition of the monticuliporid crown group is broadly similar to two earlier classifications while stem group membership matches the family Mesotrypidae. Phenetic groupings, based on overall morphological similarity, have memberships that are similar to those of clades but provide no means of determining the polarity of evolutionary relationships either within or between them. Finally, only the observed stratigraphic ranges of the type species of genera provide a statistically significant match with cladistic branching sequence, perhaps because current composite generic ranges reflect the mixing of species belonging to different genera. Based on cladogram topology, we propose the placement of all 12 genera into a single family Monticuliporidae.

Althepus pictus Thorell, 1898 is the type species of the genus Althepus Thorell, 1898 from the family Psilodercidae Machado, 1951. This genus includes 60 species from Southeast Asia (WSC 2020). A. pictus was described on the basis of one male and one female from Carin Chebà mountains, elevation 600‒800 m, Kayin Province, Myanmar. Another female specimen lacking several legs was found in Farm Caves in Mawlamyine, Mon State, Myanmar. The original description was in Latin and without any figures. Fage (1912) redescribed it based on the same male and female type specimens from Carin Chebà, but without mentioning the female from Farm Caves. Fage (1912) provided measurements, but the figures of the male right palp are imprecise. The species is redescribed here based on the original male and female type specimens deposited in Museo Civico di Storia Naturale ‘Giacomo Doria’ (MSNG) in Italy. The male and female type specimens are the only known material of A. pictus. No information is available on the female specimen from Farm Caves, which maybe have been lost. No fresh material of this species has been collected in region during five subsequent expeditions to Myanmar tours organized by the Southeast Asia Biodiversity Research Institute in the years 2016–2020.
