Relatively large, cylindrical, somewhat elongate paralimnines (4.5 to 9.5 mm long); color stramineous, with either paired red longitudinal stripes or symmetrical black spots, or both on dorsum of head and thorax. Head with crown flat, crown texture shagreen anteriorly and laterally near eyes, postfrontal suture (ecdysial line) distinct with texture posterad of line smooth and shiny, shagreen, or some combination or grade of both, coronal suture sometimes furrowed with adjacent parts of crown slightly inflated, head produced and acutely angulate anteriorly in dorsal view, much longer than basal width between eyes, crown-face transition acutely angulate in profile; lorum not extended to genal margin; anteclypeus convex, distinctly tapered distad. Forewing variably developed, may be shortened to some extent in one or both sexes exposing up to three pregenital abdominal tergites, with three closed anteapical cells, outer cell often greatly reduced in size, appendix weakly developed or absent. Hind wing present but usually reduced in size. Front tibia dorsal macrosetae usually 4+4. Male pygofer much longer than tall in lateral view, often elongated, with macrosetae distributed over most of surface, lobe with or without process or tooth; valve trapezoidal; segment X well sclerotized but not extended beyond pygofer apex; subgenital plate longer than basal width, with single row of lateral or sublateral macrosetae; connective loop shaped with stem usually short and relatively broad and anterior arms convergent anterad and touching each other or fused preapically; style with preapical lobe usually angulate, apophysis variable among species, often enlarged with denticuli; aedeagus with dorsal apodeme usually well developed, shaft tubular, apex often bifid, with or without additional processes. Female sternite VII shorter than wide, with posterior margin variably shaped among species; first valvula dorsal sculpture imbricate, extended to margin; second valvulae with basal fused section toothed at base and apex, median cleft well indicated by pigment-free area, distal toothed section slightly shorter than basal section, dorsal margin slightly arcuate with 16-30 sparse conical teeth larger and more widely spaced toward base, then becoming smaller and more closely spaced distally; arranged somewhat asymmetrically on left and right blades.</p><p>Notes. Agudus is the only genus of Paralimnini recorded from South America, and species of the genus are easily distinguished from other grass specialist South American leafhoppers by their relatively large size, cylindrical body with acutely produced head, and slightly to strongly reduced forewings, as well as by the characteristic loopshaped male connective, which is articulated to the aedeagus. Available collection records suggest that this genus is restricted to the tropical and subtropical grasslands and savannas of southeastern South America, including the Cerrado, Chaco, and Pampas biomes of Argentina, Brazil and Paraguay. The genus appears to be absent from the predominantly cool season grasslands of Patagonia and the Andes Mountains.</p><p>Key to species (males)</p><p>1.

This species, originally described from Buenos Aires, Argentina, was redescribed and illustrated by Linnavuori (1959) based on the type and an additional male specimen from a locality near Buenos Aires. It is considerably larger than other known species of the genus (males 9.5 mm long) and also differs in having a darkly pigmented ventral tooth on the pygofer lobe and the apical processes of the aedeagus sharply bent laterad near the apex. The female remains unknown. Recent collecting in pampas grasslands near Buenos Aires has failed to yield additional specimens of this species. Given the extensive urbanization and agricultural intensification in the Buenos Aires region since the species was originally collected and described, it appears that this species is now either extremely rare or extinct.</p></div>	https://treatment.plazi.org/id/03FA87E4FF82FFC6FF06FF127D14302C	Public Domain	No known copyright restrictions apply.

The female is here described and illustrated for the first time. Linnavuori (1959) indicated that the type specimen (a male) and one female paratype were deposited at USNM and one specimen (sex not stated) was retained in his personal collection. Upon initial examination of the USNM type collection, the type was not found. However, one male specimen in the main collection in a unit tray identified as A. sexmaculatus was apparently examined by Linnavuori and the genitalia match Linnavuori’s figures. His examination of that specimen is deduced by the preparation of the genitalia which are dismembered and glued to a card, a procedure that was typical of Linnavuori for specimens he examined and illustrated, including types, and was not a technique known to be used by other New World leafhopper workers. Here, the genitalia on the card were imaged and then the parts were lifted off by soaking in water and are now stored in glycerine in a genitalia vial. This male has the locality data (Loreto, Misiones; coll. AA Ogloblin) given by Linnavuori, but the date (XI-25-1931) differs slightly from what was stated for all three specimens (XII-10-1931) in Linnavuori’s publication. Despite this discrepancy, this male is interpreted here as the holotype. There are many other leafhopper specimens at the USNM from the same locality with different dates of collection, and it is possible that Linnavuori incorrectly transcribed the collection dates. The female stated by Linnavuori (1959) to be deposited at USNM was not found, although it is possible the specimen listed in Material Examined (above) with the abdomen missing is this female, and the collection date of that specimen (XII-10-1931) matches that reported by Linnavuori. Linnavuori (1959) stated that males of this species are 5 to 6 mm in length, and that the female he examined was 7.2 mm. However, these measurements seem to be inaccurate. The male type specimen is 4.5 mm, measured from apex of head to forewing apex (forewings surpass the abdomen in this species). The other three males at USNM are 4.5, 5.0, and 5.0 mm long. The specimen with missing abdomen is 5.2 mm.</p></div>	https://treatment.plazi.org/id/03FA87E4FF82FFC7FF06FB6D7F003094	Public Domain	No known copyright restrictions apply.

This species was originally described based only on females from Misiones Province, Argentina. Comparison of the holotype female to a series of recently collected males and females from northern Argentina (Corrientes) revealed that A. cyrtobrachium Cheng is a junior synonym of A. typicus . Males matching Cheng’s (1980) description and illustrations of A. cyrtobrachium were collected in association with females having the distinctive shape and markings of the pregenital abdominal segment identical to that of the female holotype of A. typicus in the U.S. National Museum. Agudus cyrtobrachium was described based on three male specimens from Paraguay.</p></div>	https://treatment.plazi.org/id/03FA87E4FF84FFC0FF06FE337D2D34C6	Public Domain	No known copyright restrictions apply.

Body length: male 4.7 mm, female 4.7–5.0 mm. Color: face medium brown with pale muscle scars, crown tan with pair of bright red submedial stripes extended from apex posterad, continuing over pronotum onto mesonotum, thin brown median line corresponding to coronal suture extended as thin reddish line across pronotum and mesonotum, pronotum with sublateral pair of less conspicuous red stripes; forewing with dark brown spot in clavus posterad of crossvein, in inner discal cell and in inner anteapical cell, spots extended into adjacent cells in some specimens. Male crown 1.3× longer than width between eyes, female crown 1.5× longer than width between eyes. Forewing short, exposing at least two pregenital abdominal tergites in both male and female; outer anteapical cell truncate apically, apical cells very short. Male pygofer 2× longer than basal height in lateral view, without basal apodemes, macrosetae scattered over entire surface except dorsally near base, apex broadly rounded, ventral margin with broad rounded lobe near base, straight in distal two thirds, inner surface without sclerotized bars or lobes. Anal tube short, cylindrical, well sclerotized laterally and dorsally. Subgenital plate half as long as pygofer, narrowly triangular with lateral margin concave, macrosetal row near lateral margin. Connective 2.5× longer than wide in ventral view, anterior arms evenly divergent, then abruptly convergent and fused near apex; stem broad and very short, truncate posteriorly. Style with preapical lobe short and broadly rounded, apophysis narrow and flattened, curved laterad, apex blunt. Aedeagus with dorsal apodeme in lateral view slender and moderately long, curved anterad, triangular in posterior view; shaft tubular, extended posteroventrad then curved posterodorsad, abruptly broadened with arcuate transverse carina on dorsal surface preapically, distal part tapered in ventral and lateral views with pair of slender spines extended distad from acute apex; gonopore preapical on dorsal surface. Female sternite VII posterior margin with pair of rounded lateral lobes flanking broad, shallow concave medial emargination.</p><p>Etymology. The species name is a Latin noun meaning “hook bearer”, referring to the hooklike aedeagus.</p><p>Material examined. Holotype male, PARAGUAY: Missiones, 191 km N. Encenada, 174 km S.
