“…Many of these species are believed to have been described in the past because their outstanding color patterns attracted the attention of taxonomists. According to Carvalho and Webb (2004) , many of these descriptions are superficial which partly explains the current shortage of information. Besides the superficial taxonomy, other aspects of these species were only partly studied, such as their bioecology and cytogenetics.…”

Spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical American beef cattle industry. Spittlebugs are an important biotic constraint to forage production and there is a lack of cytogenetic data for this group of insects. For these reasons, we conducted this work, in which the spermatogenesis and nucleolar behavior of Deois flavopicta, Mahanarva fimbriolata and Notozulia entreriana were studied. The males possessed testes in the shape of a “bunch of grapes”; a variable number of testicular lobes per individual and polyploid nuclei composed of several heteropycnotic bodies. A heteropycnotic area was located in the periphery of the nucleus (prophase I); the chiasmata were terminal or interstitial; metaphases I were circular or linear and anaphase showed late migration of the sex chromosome. The chromosome complement had 2n = 19, except for N. entreriana (2n = 15); the spermatids were round with heteropycnotic material in the center and elongated with conspicuos chromatin. The analysis of testes after silver nitrate staining showed polyploid nuclei with three large and three smaller nucleolar bodies. Early prophase cells had an intensely stained nucleolar body located close to the chromatin and another less evident body located away from the chromatin. The nucleolar bodies disintegrated during diplotene. Silver staining occurred in two autosomes, in terminal and subterminal locations, the latter probably corresponding to the nucleolus organizer regions (NORs). The spermatids were round with a round nucleolar body and silver staining was observed in the medial and posterior region of the elongated part of the spermatid head.

New Heteroptera findings of Anthocoridae (1 sp.), Coreidae (5 sp.), Cydnidae (1 sp.), Miridae (6 sp.), Nabidae (2 sp.), and Reduviidae (8 sp.) are given from Argentina. New country records are mentioned for the families Coreidae: Lybius dichrous Stål, Vilga (Vilgula) serrulata Montandon, Vilga (Laevivilga) divaricata Distant; and Reduviidae: Apiomerus flavipennis Herrich-Schaeffer, Rasahus paraguayensis Coscarón, Ricolla femoralis Distant, and R. quadrispinosa (Linné).

“…Additionally, Cercopidae have been identified as potential vectors of the bacteria Xylella fastidiosa to Brazilian grapevines (Ringenberg et al., ) and to Italian olives (Saponari et al., ). This family comprises approximately 1,450 species distributed principally in Neotropical regions (Carvalho & Webb, ; Fennah, , ; Hamilton, ; de Remes Lenicov, Paradell, & Virla, ; Soulier‐Perkins, ). Among the 24 species recorded for Argentina (Foieri & Marino de Remes Lenicov, ), the most economically important ones inhabiting the subtropical region of the country are Deois (Deois) knoblauchii (Berg), D. (D.) mourei (Berg) and Notozulia entreriana (Berg) (de Remes Lenicov et al., ).…”

The natural occurrence of entomophathogenic fungi infecting spittlebugs (Hemiptera: Cercopidae) considered serious pests to pasture grasses and crops in Argentina was investigated during summer˗autumn (December to May) from 2013 to 2016. Adults and nymphs of spittlebugs were collected from Sorghum halepense and Setaria parviflora var. parviflora in San Miguel de Tucumán, Tucumán province. The entomopathogenic fungal species were characterized on the basis of morphological keys and molecular techniques. Microscopic characters were described from material mounted in lactophenol/aceto-orcein (1% w/v), and the amplification of the fungal SSU rDNA was carried out using the universal primers nu-SSU-0021-5′ and nu-SSU-1780-3′. Summarized information about occurrence of fungal infections on spittlebugs populations is provided. This study reports for the first time the occurrence of the genus Pandora infecting adults of the economically important spittlebugs Deois (Deois) mourei, D. (D.) knoblauchii, Isozulia christenseni christenseni and Notozulia entreriana from Argentina expanding the host range and geographical distribution of entomophthoralean fungi.
