( UFVB: TR00082).    Paratypes.Same data as holotype, except  26.vii–23.viii.2017(1♁, UFVB: TR00083); same, except  21.x– 18.xi.2017(2♁♁, UFVB: TR00084).  Additional material examined. P13: 21–22.vi.2017(1♁), 28.xii.2017(1♁), 17.i–20.ii.2018(1♁), 20.ii– 21.iii.2018(1♁).   Diagnosis.The new species is very similar to  Phylloicus sallesi Barcelos-Silva, Desidério & Pes 2017,  P. bidigitatus Prather 2003,  P. obliquus Navás 1931, and  P. plaumanni Flint 1983. All these species have a median notch at the apex of segment X; the apical joint of the inferior appendage is elongate, triangular, and with three small robust bristles at the tip.  Phylloicus guarani  sp. nov.has the arms formed by the cavity of the apex of segment X round like those of  P. bidigitatusand not pointed like those of  P. sallesi,  P. obliquus, and  P. plaumanni. However, the basal part of segment X in dorsal view in the new species has a convex prominence, as in  P. sallesiand  P. obliquus. The inferior appendages of  P. guarani  sp. nov.are relatively smaller than those of  P. sallesi, approximately half the length of segment X. The new species also can be differentiated by not having the small curvature or globose expansion of the apicoventral margin of the phallobase, present in  P. sallesi.   Description. Adult male.Forewing length 9.0 mm ( holotype). Body color overall light brown, wings dark brown (in alcohol) ( Fig. 4A). Head:Central setal area dark brown; anteromesal setal wart single, heart-shaped; anterior setal wart small, round; posterior setal wart narrow, elongate. Maxillary palp setose. Antenna long, scape wide ( Fig. 4B). Thorax:Pronotum narrow with small round mesal and lateral pronotal setal warts. Mesonotum wide, with mesoscutal setal wart diffuse, reaching mesoscutellum; mesoscutellum heart-shaped ( Fig. 4B). Legs light brown. Tibial spur formula 2-4-4. Forewing forks I–V present; hind wing forks II, III and V present ( Fig. 5A). Abdomen: Preterminalic abdominal terga I–VIII each without anteromesal notch. Corematic structures absent, terga III–VIII unmodified, without membranous lobes or sclerotized processes.  Male genitalia( Figs 5B–5F): Tergum IX with dorsomesal suture subtle and short; posterior margin roof-like ( Fig. 5C); lateral suture present; dorsopleural setae present, ventropleural setae absent ( Fig. 5B); sternum IX with mesolateral suture ( Fig. 5D). Preanal appendage, in lateral view, not surpassing segment X, about as long as segment X, of uniform diameter throughout length, with setae long, but not filamentous or longer than appendage ( Fig. 5B). Tergum X without basal lobes; basodorsal and basolateral processes absent; in lateral view, subtriangular, apex narrow, round ( Fig. 5B); in dorsal view, wide at base, narrow near midlength, apex notched, notch elliptical, deep, extending through 1/3 of segment length, forming digitate posterior lobes; tergum covered with short setae dorsally ( Fig. 5C). Inferior appendage bi-articulated, short; coxopodite short, round apicodorsally, covered with long setae; harpago in ventral view almost as long as coxopodite, sharply tapered with few apical spine-like setae, in lateral view short, hooked dorsad ( Figs 5B, 5D). Phallus in lateral view slightly enlarged basally, curved caudoventrad; endotheca membranous, with paired apicolateral lobes, evident when everted; phallotremal sclerite hook-like in lateral view ( Fig. 5E), forceps-like in ventral view ( Fig. 5F).   Etymology.The specific epithet “guarani” is the name of the indigenous people who constitute one of the indigenous populations with the greatest territorial presence on the South American continent. In Espírito Santo State, the Guarani people live on the coast of the municipality of Aracruz. The name is used here as a noun in apposition with unvarying gender.   Distribution. Brazil( Espírito Santo). 4400860307 2017-06-21 2017-07-26 2017-06-21 UFVB Brazil Santa Teresa 830 -19.867369 Bragacho 1 -40.559517 Reserva Biologica Augusto Ruschi 8 309 TR00082 1 Espirito Santo holotype 4400860301 2017-07-26 2017-11-18 2017-07-26 UFVB Brazil Santa Teresa 830 -19.867369 Bragacho 1 -40.559517 Reserva Biologica Augusto Ruschi 8 309 TR00083, TR00084 1 Espirito Santo paratype
