Nisitrus Saussure, 1878 is a diurnal and monophyletic group of eneopterine crickets found in parts of Southeast Asia. Species often have vivid colourations which make them charismatic photograph subjects among macro photographers. However, their taxonomy has not been revised since their original descriptions, whereas there are also species awaiting to be discovered and described. A synoptic revision is therefore needed prior to studying the phylogenetic relationships of the genus, and before undertaking more precise studies on biogeography and evolution of traits. By holistically incorporating information about general morphology, male and female genitalia, and bioacoustics, we revise the taxonomy of these crickets and recognise 10 valid species of Nisitrus. Five new species are described: N. crucius Robillard & Tan sp. nov. from Borneo; N. danum Robillard & Tan sp. nov. from Borneo; N. hughtani Robillard & Tan sp. nov. from Sumatra; N. malaya Robillard & Tan sp. nov. from Malay Peninsula; and N. rindu Robillard & Tan sp. nov. from Borneo. We redescribe N. brunnerianus and N. insignis; describe the calls of N. malaya sp. nov., N. musicus and N. vittatus. We consider N. sumatrensis as a junior synonym of N. insignis; and N. marginata as a junior synonym of N. vittatus. Nisitrus hyalinus requires further revision. We also consider N. maculosus as a dubious name.

Handaoia Seyrig, 1952 is a small genus of Phygadeuontinae currently represented by eleven described species from Madagascar, Tanzania and Europe, and can be recognized by the combination of the distally expanded and ventrally flattened antennal flagellum, complete posterior transverse carina of the mesosternum, isolated ‘pit’ (episternal scrobe) in the mesopleuron, and a single bulla in fore wing vein 2m-cu. Most species have a distinctive combined area basalis and area superomedia on the propodeum. The following six new species from Central and South America are described and illustrated: H. cuscoensis Bordera sp. nov. from Peru, H. fritzi sp. nov. from Brazil, H. mercedensis Bordera sp. nov. from Peru, H. plaumanni sp. nov. from Brazil, H. ruizcancinoi Bordera sp. nov. from Mexico, and H. urceus sp. nov. from Brazil. A key to the New World species is provided.

Eleven new species of Amblypsilopus Bigot, 1888 from Madagascar are described and illustrated: A. analamazaotra sp. nov., A. andasibensis sp. nov., A. ankarana sp. nov., A. bairae sp. nov., A. fianarantsoa sp. nov., A. freidbergi sp. nov., A. friedmani sp. nov., A. leonidi sp. nov., A. marinae sp. nov., A. olgae sp. nov., and A. romani sp. nov. New species differ from other representatives of the genus in morphology of male surstylus and cercus mainly and male secondary sexual characters on legs. A. flavus (Vanschuytbroeck, 1962) is redescribed. Presently, ca 60 species of Amblypsilopus are known from the Afrotropical region, and 25 species are found on Madagascar. Western Indian Ocean species are associated with the Indo-Pacific A. pallidicornis group, the Pantropical A. abruptus group and the Madagascan A. stuckenbergi group of species. An identification key to males of 28 species of Madagascar and adjacent islands is compiled for the first time.

The genus Levizonus Attems, 1898 is rediagnosed and shown to contain eight species from Russia (Far East), North Korea, Japan and North-East China. One species is described here as new to science: Levizonus nakhodka sp. nov. A new formal synonym is proposed: Levizonus circularis Takakuwa, 1942 = Levizonus variabilis Lokschina & Golovatch, 1977 syn. nov., the valid name being the former. Levizonus circularis Takakuwa, 1942 is recorded for the fauna of China for the first time. All currently known species of Levizonus are included in a key, mapped and discussed.

The fauna of the bryocorine plant bug tribe Eccritotarsini from India and Sri Lanka is reviewed and updated. Ten genera and 20 species are reported from the region including two genera and six species described as new: Harpedona vittlaensis sp. nov., Lopidolon dandeliensis sp. nov., Mertila rubrocephala sp. nov., Namyatovia gen. nov. for N. castlerockensis gen. et sp. nov. (as the type species) and N. sirsiensis gen. et sp. nov., and Stonedahlia gen. nov. for S. mishmiensis gen. et sp. nov. The genus Bromeliaemiris Schumacher, 1919 is synonymized with Lopidolon Poppius, 1911. Dioclerus lutheri (Poppius, 1912) and Ernestinus ramkeshariae Yasunaga & Ishikawa, 2016 are reported from India for the first time. Differential diagnoses, keys, habitus photographs, illustrations of male genitalic structures, host and distributional information are provided for all genera and species.
