“…Deitz (1975) characterized the adults of the tribe and listed eight genera in Amastrini: Amastris Stål, Bajulata Ball, Erosne Stål, Harmonides Kirkaldy, Idioderma Van Duzee, Lallemandia Funkhouser, Tynelia Stål, and Vanduzea Goding. Hygris Stål was later referred to Amastrini (Sakakibara 1998) and the genera Neotynelia Creão-Duarte & Sakakibara (2000) and Aurimastris Evangelista & Sakakibara (2007) were later described. The nymphs of Lallemandia , Aurimastris and Hygris are unknown.…”

The immatures stages of 8 of the 11 genera (Amastris Stål, Bajulata Ball, Erosne Stål, Harmonides Kirkaldy, Idioderma Van Duzee, Neotynelia Creão-Duarte & Sakakibara, Tynelia Stål, and Vanduzea Goding) of the tribe Amastrini are described for the first time along with brief diagnoses of Membracidae and the subfamily Smiliinae. A key to genera and notes on biology are provided. Multiple species of most genera are illustrated. Based on its distinct nymphal morphology, Vanduzea laeta nolina Ball is elevated to specific rank as Vanduzea nolina stat. n., and Bajulata, despite the superficial similarity of its adults to those of Vanduzea, is confirmed as warranting generic rank based on its unique nymphal morphology. Colombia is a new country record for Tynelia.

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.

The immatures of the New World treehopper tribes Acutalini Fowler and Micrutalini Haupt (Hemiptera, Membracidae, Smiliinae)

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 ventrolaterally—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.
