“…A dissecting microscope and a compound microscope with brightfield and darkfield, as well as interference contrast, were used for the morphological observations. The morphological terminology follows mostly Bastin, et al [30], and that of the thorax Ouvrard, et al [31] and Drohojowska [32]. Measurements were taken as follows: adult body length from specimens preserved in 70% ethanol, measuring the distance between fore margin of head and tip of forewings when folded over body; the other measurements were taken from slide-mounted specimens.…”

Fossils can document the morphological diversification through time and date lineages, providing relevant characters are preserved. Primascena Klimaszewsi, 1997 was erected for P. subita Klimaszewsi, 1997 on the basis of a single, partly damaged male from Dominican amber. Originally assigned to Rhinocolidae: Paurocephalinae, the genus was subsequently transferred to Psyllidae: Aphalaroidinae. Recently, two undescribed species resembling the fossil species were discovered in Brazil (Mato Grosso do Sul), allowing a detailed morphological study of adults and immatures. Based on the morphological study, a revised diagnosis of the genus is provided, including the previously unknown female and fifth instar immatures. Primascena subita is redescribed and P. empsycha n. spec. and P. ruprechtiae n. spec. are formally described and illustrated. An identification key is provided for the species of Primascena. A cladistic morphological analysis supports the placement of the two new species in Primascena, and of this genus in the Aphalaroidinae. It is sister to all but Aphalaroida, though with little support. The two Brazilian species develop on Ruprechtia spp. (Polygonaceae: Eriogonoideae), an unusual psyllid host. Immatures of P. ruprechtiae are free-living on the lower leaf face and do not induce galls.

“…However, most of these examples have not explicitly tested whether the psyllid taxa sharing the same host are sister species and whether the speciation events may have occurred sympatrically or allopatrically. The recent description of an endemic psyllid genus in the Canary Islands that has radiated on a single, endemic Canary Island plant, Convolvulus floridus (Convolvulaceae), provides an example of this less common scenario [43]. However, although atypical in occurring on a single host, the radiation of Percyella Bastin, Burckhardt & Ouvrard on C. floridus appears to be a textbook example of allopatric speciation, whereby each of the four psyllid species is found on C. floridus but on a separate island.…”

“…There are around 4000 described psyllid species worldwide [45] and they are found in all biogeographic realms except Antarctica, with their greatest diversity in tropical and south temperate regions [27,46]. Previous studies have revealed a wide taxonomic diversity of psyllid lineages in Madeira and the Canary Islands [47][48][49][50][51], and a recent survey described two new genera and 16 new species from the Canary Islands [43]. Of the 73 species recorded for the central Macaronesian islands [43,50], there are 58 native species in 17 genera in four of the seven recognized families [45] (Table 1).…”

A molecular survey of native and adventive psyllids in the central Macaronesian islands provides the first comprehensive phylogenetic assessment of the origins of the psyllid fauna of the Canary and Madeira archipelagos. We employ a maximum likelihood backbone constraint analysis to place the central Macaronesian taxa within the Psylloidea mitogenome phylogeny. The native psyllid fauna in these central Macaronesian islands results from an estimated 26 independent colonization events. Island host plants are predicted by host plants of continental relatives in nearly all cases and six plant genera have been colonized multiple times (Chamaecytisus, Convolvulus, Olea, Pistacia, Rhamnus, and Spartocytisus) from the continent. Post-colonization diversification varies from no further cladogenesis (18 events, represented by a single native taxon) to modest in situ diversification resulting in two to four native taxa and, surprisingly, given the diverse range of islands and habitats, only one substantial species radiation with more than four native species. Specificity to ancestral host plant genera or family is typically maintained during in situ diversification both within and among islands. Characterization of a recently discovered island radiation consisting of four species on Convolvulus floridus in the Canary Islands shows patterns and rates of diversification that reflect island topographic complexity and geological dynamism. Although modest in species diversity, this radiation is atypical in diversification on a single host plant species, but typical in the primary role of allopatry in the diversification process.

The predominantly tropical tribe Paurocephalini of jumping plant-lice currently consists of seven genera and 94 described species worldwide, of which the genera Klyveria Burckhardt et al. and Melanastera Serbina et al. have been recorded from Brazil with two and one species, respectively. Here we review the taxonomy of the Brazilian species based on material collected from extensive fieldwork carried out in 15 states over the last decade. One species of Klyveria and 59 species of Melanastera are newly described, bringing the number of extant Klyveria spp. to three (both in Brazil and worldwide) and that of extant Melanastera spp. to 69 (60 in Brazil, 67 in the Neotropical region and one each in the Afrotropical and Oriental regions). The new species are described and illustrated, and identification keys for the Brazilian species are provided for adults and last instar immatures. The most diagnostically important structures are the distal segment of the aedeagus and the paramere, the forewing (shape, venation, surface spinules and colour pattern) and the female terminalia in the adults, and the chaetotaxy, tarsal arolium and shape of the additional pore fields on the caudal plate in the last instar immatures. The species descriptions are complemented by mitochondrial DNA barcodes (COI and cytB) and information on host plants. Klyveria spp. are restricted to Luehea (Malvaceae), while in Brazil 28 Melanastera spp. develop or are likely to develop on Melastomataceae, 18 spp. on Annonaceae, four spp. each on Asteraceae and Myristicaceae, and one species on Cannabaceae. Only three of the 63 species of Paurocephalini reported here from Brazil, are also known from other countries: two from Paraguay and one from Trinidad. Probably many more species of Melanastera are yet to be discovered and described. Priority in fieldwork should be given to areas that are at high risk of destruction or degradation by human activities, such as the Amazon rainforest, the Atlantic Forest and the Cerrado.
