“…The internal female sternite VIII is useful for the differentiation of species in the proconiine genus Cuerna Melichar (Nielson, 1965). Cavichioli (1997) was the first to use female genitalia in a phylogenetic analysis in the Cicadellinae, in a study of the cicadelline genus Parathona Melichar that included traits of sternite VII, pygofer and second ovipositor valvulae. Features of valvifers, first and second valvulae, gonoplacs, and sternites VII and VIII were assessed for the cicadelline genus Balacha Melichar (Takiya & Mejdalani, 2004) and provided synapomorphies of the major lineages.…”

Abstract. The Abana group sensu Mejdalani (2000) includes the genera Abana Distant, Acrobelus Stål, Acrogonia Stål, Deselvana Young, Omagua Melichar, Raphirhinus de LaPorte and Teletusa Distant. A comparative morphological study of these genera and six outgroup taxa yielded seventy‐four characters of the head, thorax, and male and female genitalia. The structures of the female genitalia, studied for the first time in a phylogenetic analysis of proconiine genera, provided informative characters for the analysis. A phylogenetic analysis conducted to estimate the relationships among these genera, using six outgroup genera, revealed eight equally most‐parsimonious trees. Goloboff's implied weights method resulted in two trees and successive weighting selected one of the original trees. The latter shows the following relationships for the genera: (Cicciana ((Acrogonia, Homalodisca) (Molomea, Tretogonia)) (Diestostemma (Desamera (Acrobelus ((Abana, Omagua) ((Raphirhinus (Deselvana sp., Deselvana ornata, Deselvana excavata)) (Deselvana dorsivitta, Teletusa))))))). The monophyly of the Abana group was not recovered, but a monophyletic group including Abana, Acrobelus, Deselvana, Omagua, Raphirhinus and Teletusa appeared in all eight trees. The genus Deselvana seems to be polyphyletic.

“…Although Cicadellinae workers usually do not describe this structure, it can bear shape‐related characteristics useful for species distinctions in the subfamily (Nielson, 1965; Mejdalani, 1995, 1998; Mejdalani & Emmrich, 1998; Takiya et al ., 1999). Cavichioli (1997) was the first to publish an analysis of phylogenetic relationships in the Cicadellinae using female genitalic characters. His study included three characters of the female genitalia, involving the pygofer, sternite VII and the second ovipositor valvulae.…”

“…The outgroup choice was based on the subjective Erythrogonia generic group assembled by Young (1977), in the absence of known phylogenetic relationships among genera in the tribe Cicadellini. These generic groupings suggested by Young (1977) have been used as a source of possible outgroup taxa in all other specific phylogenetic analyses of genera of the Cicadellini ( Draeculacephala Ball: Dietrich, 1994; Parathona Melichar: Cavichioli, 1997; Lissoscarta Stål: Felix, 1999). The outgroups selected for our analysis were species belonging to four of the twenty‐seven genera included in the Erythrogonia generic group (with the number of valid species of each genus in parentheses): Pawiloma (twelve): Pawiloma ancora Young and Pawiloma victima (Germar), Pegogonia (one): Pegogonia rufipes (Fabricius), Sibovia (twenty‐seven): Sibovia picchitula Young and Sibovia sagata (Signoret), and Caragonalia Young (two): Caragonalia carminata (Signoret) and Caragonalia tarsalis (Signoret); one genus belonging to the Dilobopterus Signoret generic group (Young, 1977: 82), Amblyscarta Stål (twenty‐five): Amblyscarta bicincta (Germar), Amblyscarta invenusta Young and Amblyscarta stillifera (Stål); and recently described Caragonia Takiya, Cavichioli & Mejdalani (two): Caragonia bella Takiya, Cavichioli & Mejdalani (see Takiya et al ., 2003).…”

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.

“…Although the New World Cicadellini are a highly diverse and economically important group, species‐level phylogenetic studies within this tribe are rare (e.g. Draeculacephala Ball: Dietrich, 1994; Parathona Melichar: Cavichioli, 1997; Lissoscarta Stål: Felix, 1999; Balacha Melichar: Takiya & Mejdalani, 2004; Scoposcartula Young: Leal et al ., 2009). Here we present a phylogenetic analysis of Apogonalia species based on 147 morphological characters.…”

A phylogenetic analysis of the leafhopper genus Apogonalia was conducted based on a matrix of 40 terminal taxa and 147 morphological characters. The analysis yielded 1391 equally most-parsimonious trees, which do not support the monophyly of Apogonalia in the strict consensus. A successive weighting procedure yielded 62 trees in which the genus appeared as a monophyletic group. The strict consensus of these 62 trees is almost entirely dichotomous, showing only two polytomies. The test of phylogenetic integrity was applied for distinct variations of three species: A. germana, A. sanguinipes, and A. histrio. Only for the first species was the conjecture that its variations belong to the same entity corroborated. The best-supported clade within Apogonalia, which has several synapomorphies and high branch support indices, comprises nine Antillean endemic species. This distributional pattern probably was originated by vicariance in the Late Cretaceous, when the Proto-Antillean archipelago was pushed north-eastward by the Caribbean Plate to become the modern Greater Antilles.z oj_724 548..570
