Three new monobasic genera and three new species of the New World treehopper tribe Acutalini (Hemiptera, Membracidae, Smiliinae) with a key to all genera (original) (raw)

Three new genera in Acutalini are described, all of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Osaria quadrilinea n. gen. et n. sp. differs from other acutalines in having a pair of suprahumeral spines and a strongly convex pronotum in lateral view. It differs from O. zacki, n. sp., in having an evenly convex, rather than stepwise convex pronotum in lateral view, in addition to other details. Quinquespinosa septamacula n. gen. et n. sp. differs in having three posterior pronotal spines. Tectiforma guayasensis n. gen. et n. sp. has the pronotum strongly tectiform throughout. //add distro gf geera A key to all genera of Acutalini is provided
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.
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.

Dysyncritus Fowler is revised based on the examination of primary types, and restructured to exclusively accomodate Dysyncritus intectus Fowler, 1895. Allodrilus Evangelista gen. nov. (type species: Cymbomorpha nitidipennis Funkhouser, 1922 = Allodrilus nitidipennis (Funkhouser, 1922) comb. nov.) is erected with seven newly discovered taxa: A. alboferrugineus Evangelista sp. nov. (Brazil, Colombia, Guyana), A. colombiensis Flórez-V sp. nov. (Colombia), A. deitzi Evangelista sp. nov. (Ecuador), A. granulatus Evangelista sp. nov. (Ecuador), A. horizontalis Evangelista sp. nov. (Bolivia), A. intermedius Evangelista sp. nov. (Ecuador), and A. similis Evangelista sp. nov. (Peru). A key to males is provided, in addition to annotated descriptions and illustrations. Nomenclatural changes are proposed to species formerly included in Dysyncritus:
Treehoppers (Hemiptera: Aetalionidae and Membracidae) from Madre de Dios region, Peru
Revista Peruana de Biología
A list of treehoppers (Aetalionidae and Membracidae) is presented from Madre de Dios region at the southeastern Amazon basin in Peru. The treehopper specimens were collected as by-catch in a survey of the beetles in the Villa Carmen Biological Station and Los Amigos Biological Station. The list comprises 44 species, 31 genera, 16 tribes and 9 subfamilies. Ten genera are new records to Peru. The images of representative specimens of each identified species and genera are provided to facilitate the identification of the local treehopper fauna.
Updated checklist of treehoppers of Panama (Hemiptera: Membracidae) with plant associations
Zootaxa, 2024
An updated checklist of treehoppers (Hemiptera: Membracidae) of Panama is provided with known province distribution data. The world catalogue of Membracoidea, through April, 1997, lists 68 genera, 162 species, and 1 subspecies from Panama (McKamey, 1998). Flynn (2012) listed all known species from Panama, documenting range extensions for 29 genera, 107 species, and 1 subspecies previously unknown from Panama, bringing the treehopper fauna from Panama to 97 genera, 269 species, and 2 subspecies. Inspection of 768 additional specimens since 2012 (new total of 3,595 specimens for the study), in addition to published literature, has added 2 new genera and 40 new species bringing the treehopper fauna to 100 genera (increase of 3 genera), 313 species (increase of 44 species) from 2012, and 2 subspecies. Many new provincial sites were added to each species with an updated provincial map showing numbers of species in each province. Updated species counts per Province (with increase): Bocas del Toro 65 (+10), Chiriqui 162 (+11), Veraguas 26 (+3), San Blas 8 (+1), Herrera 9 (+1), Darien 72 (+13), Los Santos 4 (+1), Cocle 43 (+9), Colon 187 (+79), and Panama 150 (+32). Tables listing published checklists and keys for Nearctic and Neotropical treehoppers are presented.
