Chen Z. et al.: "Descriptions of two new species of the enigmatic Neotropical tribe Chryxini (Hemiptera, Heteroptera, Reduviidae) and a key to genera and species with single membrane cell".

The Chryxini Champion, 1898, previously recognized as a subfamily of the Reduviidae Latreille, 1807, is now placed in the Reduviinae Latreille, 1807 as a tribe to accommodate five genera and 18 species from the Neotropical Region. Many species of the Chryxini are rarely encountered in the field as well as in museum collections, and their systematics, morphology, and ecology are still poorly understood. In the present study, two new species of the Chryxini, Chryxus willemsei Chen, Hartong & Cai, n. sp. (from Commewijne, Suriname) and Wygodzinskyella gilsantanai Chen, Li & Cai, n. sp. (from Río Grande do Sul, Brazil), are described and illustrated. The Chryxus genus group is proposed to include Chryxus Champion, 1898, Lentia Wygodzinsky, 1946, Petasolentia Weirauch, 2012, and Wygodzinskyella Usinger, 1952; this genus group is characterized by the tuft of long setae on the mesopleuron and the single membrane cell on the hemelytron; other related morphological characters are also discussed. An identification key to the genera and species of the Chryxus group is provided. The Chryxini and Chryxus are newly recorded from Suriname.

Dellapé P.M., Melo M.C.: "Three new species of Dushinckanus Brailovsky (Heteroptera, Rhyparochromidae, Myodochini), description of the male of D. camelopardus Harrington, and new distributional records for known species".

In this contribution, the diagnostic characters of the myodochine genus Dushinckanus Brailovsky, 1979 are discussed. The male of D. camelopardus Harrington, 1987 is described for the first time, and its distribution is extended north to French Guiana, as is that of D. ashlocki Harring, 1987. Additionally, three new species from French Guiana are described. Dorsal habitus and male genitalic photographs are provided and an updated key to separate the species in the genus is given.

Malipatil M.B. & Liu Y.: "Additions to the knowledge of Stylogeocoris and Umbrageocoris of Australia (Hemiptera: Heteroptera: Geocoridae)".

The recent discovery of the type specimen of Geocoris provisus Bergroth, 1895 (Hemiptera: Heteroptera: Geocoridae) has necessitated the following new subjective synonymy: Stylogeocoris provisus (Bergroth, 1895), comb. nov. = Stylogeocoris elongatus (Distant, 1901), syn. nov. Umbrageocoris malipatili Kóbor, 2022 is redescribed and illustrated, comparative notes are provided for Umbrageocoris Kóbor, 2019 and Geocoris Fallén, 1814 as well as for some species of these two genera from Australia. Stylogeocoris bicoloratus Malipatil, sp. nov. is described, and an updated key to the species of genus Stylogeocoris Montandon, 1913 is presented.
