Most of the recent comprehensive taxonomic research on Smiliinae has focused on the tribes Acutalini (Sakakibara 1997), Amastrini (Evangelista and Sakakibara 2007), Ceresini (Andrade 2004), Micrutalini (Sakakibara 1999), and Polyglyptini (Sakakibara 1996), although Cast (2002), in his Master's thesis, conducted a phylogenetic analysis of the Smiliinae using four mitochondrial genes.…”

Members of the Smiliini, the nominotypical tribe of the large New World subfamily Smiliinae, are predominately Nearctic in distribution. This tribe included 169 mostly tree-feeding species in 23 genera. A parsimony-based phylogenetic analysis of an original dataset comprising 89 traditional and newly discovered morphological characters for 69 species, including representatives of 22 of the 23 described genera of Smiliini and five other previously recognized tribes of the subfamily, resulted in a single most parsimonious tree with three major clades. The broad recent concept of Smiliini (including Telamonini as a junior synonym) was not recovered as monophyletic by the analysis. Instead, the analysis supported narrower definitions of both Telamonini, here reinstated from synonymy, and Smiliini. A key and diagnoses are given to define these tribes, along with discussions of their phylogeny, biogeography, and host plant associations. The genera Antianthe Fowler, Hemicardiacus Plummer, Smilirhexia McKamey, and Tropidarnis Fowler are placed as Smiliinae, incertae sedis. Based on the phylogeny, several genera from both tribes including Atymna Stål, Cyrtolobus Goding, Heliria Stål, and Telamona Fitch are not monophyletic. Diagnostic characters emphasizing the morphological differences between the Smiliini and Telamonini include the dorsal margin of the head, the shape of the pronotum, the size of the pronotal humeral angles, the presence or absence of pronotal longitudinal rugae, the size of forewing cells, variations in the fusion of veins R and M apically in both the foreand hind wing, and the shape of the apex of the female second valvulae. Mapping geographic distribution onto the phylogeny suggests that the common ancestor of the ingroup (all three clades) occurred in Central America and Mexico, with multiple dispersals to temperate North America. Many Smiliini and Telamonini feed on various species of oak (Quercus) and the close evolutionary association between these insects and their hosts is discussed.

“…Mistakes concerning localities of old specimen labels are apparently common in the Cicadellidae as noted by Schröder (1959) for Molomea biimpressa (Signoret), Mejdalani et al . (2000) for Amblyscartidia spinolai Mejdalani, Felix & Takiya, Young (1968) for Splonia acutalis Signoret, and Young (1977) for Sibovia sagata (Signoret), and in the Membracidae, as noted by Sakakibara (1999) for Micrutalis flavozonata (Fairmaire) and Micrutalis tripunctata (Fairmaire). Although it seems that specimens of the Signoret collection do not bear their original locality labels, it is apparently not a mistake of some later re‐labelling of the material, as the type locality in the original description of Tettigonia distincta is indeed given as Colombia.…”

Abstract. Balacha currently includes six valid described species and B. caparao sp. nov., here described from Minas Gerais State, Brazil. The new taxon differs from other Balacha species in the ventrally inflated preapical aedeagal area and oblique bases of the ovipositor first valvulae. New records are as follows: B. decorata from Paraguay and Minas Gerais State (Brazil); B. distincta from Brazil; B. melanocephala from Montevideo Department (Uruguay) and Buenos Aires and Distrito Federal provinces (Argentina); and B. similis from Rio de Janeiro and Minas Gerais states (Brazil). Colombia is considered a dubious record for the genus. Phylogenetic relationships among Balacha species are examined based on a matrix of eighteen terminal taxa and sixty‐seven morphological characters. Balacha may be defined by the following synapomorphies: crown–frons transition approximately acute, crown anteriorly produced and with anterior margin subangulate, flattened pronotum continuing contour of head and mesonotum in lateral view, and teeth of second valvulae of ovipositor with anterior dorsal projection. The genus comprises two major lineages: the red Balacha clade (B. lepida(B. distincta + B. rubripennis)), and the black Balacha clade (B. caparao(B. decorata(B. melanocephala + B. similis))). Despite the scarcity of data on host plant usage of outgroup taxa (probably generalists on Lamiaceae, Lauraceae, and Asteraceae), we believe that the shift to feeding on Eryngium(Apiaceae) occurred in the ancestor of all recent Balacha species. Their small size and depressed body appear to be adaptations to living inside the rosette‐disposed leaves, and they seem to be restriced to this microhabitat. Balacha and their Eryngium hosts occur in grasslands in temperate South America, but at lower latitudes in Brazil they are isolated in alpine meadows on peaks of the southeast highlands. Dispersal between such areas through the lowland humid Atlantic forest in recent times would be difficult, thus the ancestor of Balacha was probably distributed in southeast South America before the uplift of the mountain ranges, during the late Eocene or Oligocene. This event may have triggered speciation of some lineages of the genus by vicariance.

Sakakibara (1976) described two new species; Deitz (1983) referred one species to Rhexia Stål, and Sakakibara (1999b) provided a synopsis of Micrutalis, including 42 species. In the present study, nymphs and adults of two Micrutalis species were also collected on Cordia, one in Ecuador and another in Nicaragua (see Material Examined under Micrutalis).…”

The nymphs of Acutalis Fairmaire, Bordoniana Sakakibara, Thrasymedes Kirkaldy, and Micrutalis Fowler are described and illustrated (Bordoniana and Thrasymedes for the first time). The nymphs of all four genera are exceedingly cryptic. The nymphs of some species lack scoli on the head and pronotum but all have paired scoli on the meso- and metathoracic nota and abdominal segments III-IX. Some species also have lateral rows of enlarged chalazae on the abdomen, and even large scoli ventrolateral—the latter condition is unique within Smiliinae. The eggs are deposited in stems (not in exposed masses) and nymphs are solitary and not ant-attended. The fifth instar nymphs of Micrutalini range in length from 3.0-3.5 mm, much smaller than the fifth instars of most other treehoppers.
