Platygerris White comprises true bugs that inhabit the surface of water in moderate to fast-flowing freshwater habitats. This genus differs from Cylindrostethus Mayr and Potamobates Champion (Gerridae: Cylindrostethinae) by having a short and flattened body; the mandibular and maxillary plates fused; and the omphalium, lateral groove, and lateral evaporatorium of the scent apparatus inconspicuous. In this paper, we redescribe Platygerris, describe two new species from Colombia, and redescribe P. asymmetricus Hungerford, P. caeruleus Champion and P. depressus White. In addition, we present an updated identification key to the species of the genus. For the first time, the cuticular structure is described for the genus based on electron microscopy.

The present study was carried out in the Khuzestan province of Iran during 2016−2017. In total, five species of the genus Iconella were collected and identified, of which two new species are described and illustrated: Iconella mongashtensis Zargar & Gupta sp. nov., and I. similus Zargar & Gupta sp. nov. One species, Iconella meruloides (Nixon 1965), is recorded for the first time from Iran and two species, Iconella myeloenta and I. subcamilla, are new provincial records. The number of Iconella species in Iran is now raised to eight. An identification key to all Iranian species of the genus Iconella is provided.

In the present study, we analyzed the taxonomy and ecology of fourteen species of Luticola registered in oligo- to hypereutrophic reservoirs of southeastern Brazil. Two new species were described using light and scanning electron microscopy. Luticola bartolomeii sp. nov. and Luticola iporangensis sp. nov. are distinguished from morphologically similar species by a combination of valve outline and dimensions. In addition, L. bartolomeii showed occluded isolated areolae that have a different shape and location, hitherto not observed in other Luticola species. We also compared the morphology of the new species with similar taxa and provided information on their ecological preferences. Luticola panamaensis is first recorded in Brazil, and another eight species are recorded for the first time for the state of São Paulo. This study expanded the distribution of species and added new information to the ecology of Luticola, as well as provided the first SEM images for some already known species. Information on the co-occurrence of other diatom species in the samples is also included.

In this paper we revise the chordeumatidan genus Haasea Verhoeff, 1895 for the first time and describe two new species viz., H. gruberi sp. nov. and H. makarovi sp. nov. discovered in Austria and Serbia, respectively. A new terminology is proposed to standardize the description of the gonopod structures in the genus. Type material obtained from several institutions was examined and documented herein, whereby lectotypes are designated. We clarified the taxonomic status of a few taxa and consider the species H. norica (Verhoeff, 1913) and H. guidononveilleri Makarov, 2008 as a junior subjective synonyms of H. cyanopida (Attems, 1903) and H. vidinensis (Strasser, 1973a), respectively. The following subspecies or varieties, viz., Orobainosoma filicis ossiacum Verhoeff, 1939b, Orobainosoma flavescens vornatscheri Verhoeff, 1935, Orobainosoma hungaricum orientale Tabacaru, 1965, and Orobainosoma inflatum var. aspidiorum Verhoeff, 1929 are here regarded as junior subjective synonyms of their nominal taxa. The taxonomic relationships within the genus Haasea are discussed and an identification key to its 17 species is presented, based on number of body segments and gonopod structures.                Maps showing species occurences based on historical and recent records are presented to understand their respective geographic ranges. H. flavescens is now deleted from the list of species in Croatia, Bosnia and Herzegovina, Slovenia and Italy as these records were based on misidentified material. H. inflata is deleted from the fauna of Bosnia and Herzegovina, whereas H. hungarica is newly recorded from Austria, Serbia and Slovenia.

Both species were characterized morphologically and by DNA barcoding of the mitochondrial COI gene.
