A new genus, Renorphnus gen. n, is established for the Madagascar species Orphnus clementi Petrovitz. The new genus differs from other representatives of Orphninae in distinctive shape of the fore tibia of male, shape of clypeus, presence of 2 more or less prominent tubercles on pronotum in both sexes, and widened and pectinate setae on costal margin of wings. Orphnus clementi is redescribed. Diagnostic key to Madagascar Orphninae genera is given.

A new genus and a species of Saicinae, Kiskeya palassaina, n. gen., n. sp., are described from the Dominican Republic. The armature of the fore leg of the nine apterous female specimens are unique among genera of Saicinae in consisting of spines on the fore femur, but of stiff setae on the fore tibia. A key to the New World genera is given. Digital macrophotographs, scanning electron micrographs, and illustrations are provided.

The endemic Australian tribe Myiotrixini is reviewed and a new genus andspecies described. The monotypic genus Myiotrixa Brauer & Bergenstamm, 1893, is known from all States except the NorthernTerritory, but has been most frequently collected from south-easternAustralia; the single species, M. prosopina, is aparasite of the native Australian cockroachPlatyzosteria castanea Brunner.Obscuromyia, a new monotypic genus of Myiotrixini fromnorthern Western Australia, is described and the relationship between it andMyiotrixa discussed. Striking synapomorphies of the maleand female terminalia corroborate the sister-group relationship betweenObscuromyia and Myiotrixa. These synapomorphies are the medially fused pregonites which encircle the base ofthe aedeagal apodeme in the male, and in the female the lack of sclerotisedsternites in most of the abdomen and ovipositor, and the non-extensible andnon-piercing ovipositor in which segment 8 forms a sclerotised cylinderincised dorsally and ventrally. A revised diagnosis of the Myiotrixini isprovided along with a diagnostic key to the two genera.

We present the description of a new genus and species of soldierless termites from South America. Rustitermes boteroi Constantini, Castro & Scheffrahn, gen. et sp. nov. can be identified by the morphology of the enteric valve, with six slightly asymmetric cushions, each one forming a central pouch made of scales smaller than those between the cushions. The new genus features two characteristic rows of thick bristles on the interior margin of the fore tibia, and is supported by COI molecular sequence data. This species is distributed from Tobago to northern Argentina.

<em>Madachironomus</em> gen. n. is described based on male and female imagines collected at two watersheds in Madagascar. Two species are included, <em>M. lakazana</em> sp. n. from Lakazana River, Antananarivo province and <em>M. rongaronga</em> sp. n. from Rongaronga River, Toamasina province. The adults have a black comb on the apex of the fore tibia, similar to the combs on mid- and hind tibiae, thus placing the new genus in the tribe Pseudochironomini Sæther. The male has a strong, moderately long, nearly parallel-sided anal point with broadly rounded apex, without microtrichia except at base, and a digitiform, apically split median volsella with strong brush-like setae, projecting medially. The female sternite VIII has a very dense posteromedial to posterolateral field of setae, the gonocoxapodeme VIII is nearly straight, the gonapophysis VIII has closely adjacent, indistinctly separable lobes; the ovoid seminal capsules have nearly straight spermathecal ducts and the labia have internal apodemes and spinose chaetulae on dorsomedial surfaces.

Recent published molecular analyses have shown that the genus Polycarpon is polyphyletic and includes only the members belonging to the Polycarpon tetraphyllum aggregate. Morphologically, dehiscence of the capsule by valves that elastically roll inwards and eject the seeds provides a clear synapomorphy for Polycarpon in this restricted sense. Among the excluded taxa, the South American P. anomalum, P. suffruticosum and P. coquimbense are not described taxonomically, although molecular and morphological evidence exists. We here propose to recognise these species as a new South American endemic genus (Augustea gen. nov.) with three recognized species. The names Polycarpon suffruticosum (var. suffruticosum, and var. virens), P. australe, and P. anomalum are lectotypified. A diagnostic key is provided, as well as descriptions, ecological information and distribution for each species.

A new genus and species of the family Dinglidae Szwedo & Drohojowska , 2020 (Hemiptera: Sternorrhyncha), Alloeopterus anomeotarsus, is described from mid-Cretaceous Burmese amber. The new genus is characterized by a simplified forewing venation with thick veins of R and M+Cu emerging separately from the wing base, a diffuse pterostigma close to termination of RA vein, reduced vein A1, veins M and Cu unbranched, a reduced clavus, a small hindwing with a costal margin and terminal R vein weakened in apical portion; a long first flagellomere, approximately 1.5 times as long as the second flagellomere and rhinaria with sensory pits on the apex of the pedicel and flagellomeres 5 and 6. The fossil increases our knowledge of the morphological variation that occurred during the evolution of Cretaceous Sternorrhynchia.

The phylogeny of Heterocaryum and Suchtelenia was examined using sequence data from the internal transcribed spacer region of the nuclear rDNA (ITS) and plastid trnL intron and trnL–trnF intergenic spacer (trnL–F) regions. Results indicated that Heterocaryum is non-monophyletic because of the inclusion of Suchtelenia calycina (C.A.Mey.) A.DC. Heterocaryum laevigatum (Kar. & Kir.) A.DC. formed a distinct branch sister to S. calycina and remaining Heterocaryum species. Hence, all species of Heterocaryum except H. laevigatum (type species of the genus) are transferred to a new genus, Pseudoheterocaryum. Taxonomic descriptions are presented for Pseudoheterocaryum and Heterocaryum, as well as a diagnostic key to the three genera included in the present study.

A new genus of Baetidae, Pedicelliopsgen. nov., and a new species, P. capillifersp. nov., are described from Guinea (West Africa) based on larvae. The new genus is characterized by having strongly enlarged pedicelli and very short flagella, a brush of dense, short setae between prostheca and mola of both mandibles, a small rectangular labrum, an apicolaterally pointed maxillary palp, a labial palp with a small distolateral protuberance and long setae ventrally on glossae and paraglossae. The femora of all legs are covered with numerous long, fine setae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is pointed with two rows of denticles. No spines are present on the posterior margins of the abdominal tergites. The imago remains unknown and the relationships with other African genera of Baetidae remains tentative. Despite being easily identifiable and of a fairly large size (body length ca. 5 mm), only two larvae were found in two highly sampled localities in West Africa.

A new genus of Baetidae, Megalabiopsgen. nov., and a new species, M. madagasikarasp. nov., are described from Madagascar based on nymphs. The new genus is characterized by having a strongly enlarged mentum; pedicelli with many long, stout, pointed setae; a brush of dense, short setae between prostheca and mola of both mandibles; an apically pointed maxillary palp with a stout seta at the tip; and a labium with many long, simple setae ventrally on glossae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is strongly elongated with two rows of denticles. The imago remains unknown and the relationships with other African genera of Baetidae are tentative. Despite being easily identifiable, only two nymphs were found in two highly sampled localities in Madagascar.

Zaragozachthonius siculus n. gen. n. sp. is described from Sicily and Z. karamanianus (Hadži, 1937) (n. comb.), originally described from Macedonia, is newly recorded from central-southern Italy and Sicily. Relationships of the genus Zaragozachthonius among the other Chthonius-related genera sensu Zaragoza (2017), are discussed and a diagnostic key is proposed.
