“…Image adjustments included crop, color brightness and contrast and unsharpen mask. Morphological terms mainly follow Blocker and Triplehorn (1985), Zahniser and Dietrich (2008) and Stiller 2016, Stiller 2019a, Stiller 2019b, chaetotaxy follows Rakitov (1997). Measurements included length from apex of crown to apex of tegmina, crown median length, crown length perpendicularly next to compound eye, pronotum length, head width across eyes, pronotum width, ocellus diameter and interocular distance between ocellus and compound eye.…”

Two new genera of macropterous leafhoppers, tentatively included in the tribe BonaspeiiniZahniser and Dietrich (2013) from the Fynbos biome of south-western parts of South Africa, are described. These are Retevolatusgen. nov. with type species R. flexiverpussp. nov., R. semicurviverpussp. nov. and R. subspiniverpussp. nov. and Flavorubivolatusgen. nov. with type species F. glabriverpussp. nov. and F. tensiverpussp. nov. and F. curtiverpussp. nov. Collection records and distribution modelling confirmed that species of both genera occur within a confined region of south-western parts of South Africa.

On the morphology and evolution of cicadomorphan tymbal organs

Cicadas and many of their relatives (Hemiptera: Cicadomorpha) generate vibroacoustic signals using tymbal organs located on their first two abdominal segments.Although tymbals are well-studied in Cicadidae, their systematic distribution in other Cicadomorpha and their possible homologies to the vibroacoustic mechanisms of other Hemiptera have been debated for more than a century. In the present study, we re-examine the morphology of the musculoskeletal system of cicadomorphan vibroacoustic organs, and we document their systematic distribution in 79 species drawn from across the phylogeny of Cicadomorpha. We also compare their morphology to the recently-described snapping organ of planthoppers (Fulgoromorpha). Based on the structure and innervation of the metathoracic and abdominal musculoskeletal system, we find that several key elements of cicadomorphan vibroacoustic organs that have previously been assigned to the first abdominal segment in fact belong to the second. We find that tymbal organs are nearly ubiquitous in Cicadomorpha, and conclude based on their phylogenetic distribution, that they are likely to be synapomorphic.The unusual tymbal-like organs of the Deltocephalinae and Typhlocybinae, represent derived modifications. Finally, we propose a standardised terminology for sternal components of the cicadomorphan vibrational organs, which can be used in future taxonomic descriptions.

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.
