This study focuses on the genus Dioncomena and its acoustics, particularly the unique songs produced by male Dioncomena that consist of several distinct elements in a fixed sequence, culminating in a coda that typically elicits a response from a receptive female. We also examine the inflated pronotal lobes, which we term prebullae, that are prominently developed in some Dioncomena species but not in others. We discuss the role of prebullae in the context of acoustic communication in Dioncomena and other related Phaneropterini genera that have similar lateral pronotal lobes. We found that prebullae size is correlated with habitat distribution, with larger prebullae occurring in isolated species while aggregation-prone species have smaller or less pronounced prebullae. Using micro-computer tomography we show sexual dimorphism in the 3D geometry of the acoustic tracheae, being larger in the male. Interestingly, the tracheae are coupled by a septum, like in field crickets, which suggests potential cross talk. We define three groups of Dioncomena based on altitude preferences, ecology, color patterns, and songs: the jagoi-, tanneri-, and ornata-groups. We describe the songs of several species, including newly identified species such as D. flavoviridissp. nov., D. magomberasp. nov., D. ngurumontanasp. nov., D. sanjesp. nov., D. tanneri, D. versicolorsp. nov., and D. zernyi. We also provide information on the nymphs, development time, and mating behavior of various species reared in the laboratory, shedding light on their phenology and adaptations to their habitats.

The Mediterranean region representsone of the hotspots of biodiversity of many organisms and among these also of Raphidioptera. With about 250 known species world-wide Raphidioptera is the smallest order of extant holometabolous insects. The Mediterranean region harbors 113 species (= >45% of the world fauna), and of these 33 (= >13% of the world fauna) have been found on islands of the Mediterranean Sea. In the course of the past 50 years most of the larger islands have been intensively explored for Raphidioptera, particularly all islands (except the Baleares) which had no connection to the mainland throughout the whole Pleistocene. Altogether, 11 species of Raphidioptera (9 Raphidiidae, 2 Inocelliidae) are endemic to (usually)one, rarely to a few Mediterranean islands: Phaeostigma (Ph.) euboica (Euboea), Ph. (Aegeoraphidia) prophetica (Rhodes), Ph. (Ae.) karpathana (Karpathos), Ph. (Ae.) biroi (Crete), Ph. (Superboraphidia) minois (Crete), Subilla principiae (Sardinia), S. colossea (Rhodes), Raphidia (R.) peterressli (Chios), R. (R.) ariadne (Crete), Fibla (F.) maclachlani (Corsica, Sardinia, Sicily), F. (Reisserella) pasiphae (Crete). In the Aegean Sea there is a remarkable difference between the eastern and the western islands marked by the so-called Rechinger line based on results of the analysis of the flora. The Raphidioptera confirm this line impressively. It is rather unlikely that further Raphidioptera species endemic to Mediterranean islands are still to be detected – with one exception: the Baleares. A few additional species known from various parts of the continents surrounding the Mediterranean Sea will probably be found on islands so that a total number may be around 40, possibly around 45 species. The possible ways and times of colonization of the islands by Raphidioptera are discussed. The present paper may serve as a basis for studies on natural and particularly on anthropogenic dispersals of snakeflies from island to island, from mainland to islands, and from islands to the mainland in connection with phylogeographic investigations.

The tribe Choriphyllini Cadena-Castañeda & Silva, 2019 consists of only two genera, Choriphyllum Serville, 1838 and Phyllotettix Hancock, 1902b, combining leaf-like Caribbean wide-nosed pygmy grasshoppers (Tetrigidae, Cladonotinae). The genus Choriphyllum has four species, C. bahamense Perez-Gelabert & Otte, 1999 from the Bahamas (Hummingbird Cay Island), and C. sagrai Serville, 1838, C. saussurei Bolívar, 1887 and C. wallaceum Skejo, Kasalo & Yong, sp. nov. from Cuba. The gender of C. bahamensis is changed to C. bahamense in order to match the grammatical gender of the genus, which is neuter. Silva’s designation of C. sagrai, the type species of Choriphyllum, as nomen dubium in 2019 was incorrect as Serville’s drawing clearly points to this species, endemic to Cuba, so nothing about its identity is doubtful. The genus Phyllotettix is endemic to Jamaica, where four species live: P. rhombeus (Felton, 1765), P. foliatus (Hancock, 1902a), P. compressus (Thunberg, 1815) and P. plagiatus (Walker, 1871), comb. nov. of Choriphyllum plagiatum. Choriphyllum westwoodi Hancock, 1902a, syn. nov. is synonymous with Phyllotettix rhombeus and not with P. compressus. A new subgenus is established, Phyllotettix (Rhombotettix)subgen. nov. for P. (R.) plagiatuscomb. nov. and P. (R.) rhombeus. A new species complex, Phyllotettix (compressus)sp. complex nov. is established for two morphologically close species, P. compressus, and P. foliatus; while another new species complex, Choriphyllum (sagrai)sp. complex nov. includes C. sagrai and C. wallaceumsp. nov. An annotated key to genera, subgenera, species groups and species is provided.

We review the genus Anacaena Thomson, 1859 from the Ryukyu Archipelago, southern Japan. Three aquatic species are recognised: A. torikaiisp. nov. from Amami-ôshima Island, A. okinawanasp. nov. from Okinawa-jima Island and Kerama Islands, and A. kumejimanasp. nov. from Kumejima Island. All three species are very similar, with the morphology of the aedeagus being essential for a reliable identification. Dorsal colouration is also useful as a diagnostic character, despite some variation within species. We observe a possible geography-based variation between A. okinawana from Okinawa-jima I. and the neighbouring Kerama Is., but we treat both populations as conspecific based on genital morphology. Anacaena kumejimana and A. okinawana share many morphological characters possibly indicating their close relationship. We compare the endemism of aquatic Hydrophilidae in the Ryukyu Archipelago to that in other groups of aquatic beetles: the proportion of endemic species is higher in aquatic Hydrophilidae than in Dytiscidae, but much lower than in stream-inhabiting Hydraenidae and Elmidae. A list of Japanese species of Anacaena and a key to the Japanese species of the genus are provided.

Feuerborniella sinefurcata Kvifte & Jaume-Schinkel, sp. nov. is described, based on material from Tanzania, representing the second Afrotropical species of the genus following Psychoda morogorica Wagner & Andersen, 2007 which we treat as Feuerborniella morogoricacomb. nov.

A remarkable new genus and species of Nevrorthidae, Sisyroneurorthus aspoeckorumgen. et sp. nov., is described from mid-Cretaceous Kachin amber of northern Myanmar. This new species is the second Mesozoic representative of Nevrorthidae. The distal fusion of ScP and RA in the forewing of this new genus is shared by most Sisyridae. Given the probable sister-group relationship between Nevrorthidae and Sisyridae, our study sheds light on the evolution and morphological diversity of Nevrorthidae in the Mesozoic era.

A comparative SEM study of palp sensory surfaces in 25 caddisfly species representing seven families reveals seven types of sensilla: long trichoid, blunt chaetoid, campaniform, mushroom-like pseudoplacoid, petaloid, thick basiconic and thin basiconic sensilla. Long trichoid and chaetoid sensilla are present on all segments of both pairs of palps. First and second segments of maxillary palps bear groups of long and sclerotised chaetoid sensilla on their medial surface. Other segments of maxillary palps and all segments of labial palps have shorter and thinner chaetoid sensilla mainly on their ventromedial surfaces. Campaniform sensilla usually occur on the first segment of labial palps and second segment of maxillary palps. Mushroom-like pseudoplacoid sensilla may occupy all palp segments or only distal ones. Petaloid sensilla form sensory fields on apical segments of both pairs of palps in most studied species. Thick basiconic sensilla occur only in apical sensory complexes on tips of maxillary and labial palps. A comparison with the Lepidoptera suggests the similarity in palp sensilla and conservative evolution of the palp surface. The reconstructed ground plan for the palp sensory surfaces in Trichoptera and Amphiesmenoptera is provided.

The leafhopper genus Hadroca Theron, 1974 with type species Euscelis ramosa Naudé, 1926 is re-defined here by examination of long series of specimens with varied color and wing polymorphic males and females. Five new species are added: Hadroca alacaudellasp. nov., H. alavittatasp. nov., H. bualacaudasp. nov., H. hapsistylissp. nov. and H. treichroasp. nov. The genus is known only from South Africa, mostly from the Fynbos Biome. All species have the aedeagus C-shaped and uniformly sclerotized, the shaft gradually tapered, commonly edentate, rarely with single, subapical, anterior process and the style with distal apophysis curved ventrad. A key to species is provided, with discussion on the differentiation from similar genera such as Bloemia Theron, 1974, Basutoia Linnavuori, 1961 and Tzitzikamaia Linnavuori, 1961 and distribution maps.
