Measurements (mm). Male holotype: total length 5.27; crown length 0.50; transocular width 1.22; interocular width 0.57; maximum pronotal width 1.23; forewing length 4.30. Male paratypes (n=4)/female paratypes (n=3): total length 4.45–5.02/4.85–5.46; crown length 0.42–0.48/0.48–0.51; transocular width 1.08–1.24/1.16–1.27; interocular width 0.52–0.56/0.56–0.60; maximum pronotal width 1.08–1.20/1.16–1.28; forewing length 3.60–4.10/3.95–4.60.

Description. Head ( Fig. 1 ) with median length of crown from 8/10 to 9/10 interocular width and 4/10 transocular width. Pronotum ( Fig. 1 ) width similar to transocular width. Forewing ( Fig. 2 ) with open inner anteapical cell; median cell approximately as long as outer one. Hind leg with femoral setal formula 2:2:1; length of basal tarsomere greater than combined length of two succeeding tarsomeres.

Male terminalia. Pygofer ( Fig. 3 ), in lateral view, short and slightly narrowed towards rounded apex; basidorsal margin with inner acute process, directed posterad and parallel to basal portion of anal tube; dorsal margin mostly concave, ending in short triangular projection; dorsal portion of pygofer with few long macrosetae forming oblique row, some short macrosetae near triangular projection. Valve ( Fig. 4 ), in ventral view, approximately as long as broad, somewhat elliptical, posterior margin broadly rounded. Subgenital plate ( Fig. 4 ), in ventral view, long, extending posteriorly beyond pygofer apex; dorsally curved; basal 1/3 with transverse membranous rounded line; apical 1/3 slightly expanded ventrally; apex rounded; ventral longitudinal row of four long macrosetae on median 1/3. Style ( Fig. 5 ), in dorsal view, long and narrow, extending posteriorly well beyond connective apex; preapical lobe well produced; apical portion long and acute, slightly curved outwards, forming hook with preapical lobe, tiny dentiform subapical projection on outer margin.

Crown ( Fig. 1 ) entirely light yellowish-brown except for pair of large, oblique elliptical brown spots on basal 1/2, attaining imaginary line between anterior eye angles; ocelli narrowly bordered by ivory. Eyes brown. Pronotum ( Fig. 1 ) light brown with numerous small ivory spots; anterior portion with large brown areas. Mesonotum ( Fig. 1 ) ivory with anterior pair of large brown spots; scutoscutellar suture brown. Forewing ( Figs 1, 2, 8 ) translucent; veins mostly marked with alternating brown and ivory; costal margin with large, oblique irregular ivory macula bordered anteriorly and posteriorly by brown, located approximately opposite apex of clavus; basal veins of apical cells marked with brown; apical cells with large brown areas. Face ( Figs 9, 10 ) pale yellow to brownish-yellow. Thoracic sclerites ( Figs 8, 10 ) pale yellow laterally and ventrally. Legs ( Fig. 8 ) pale yellow with some darker areas; apices of tarsi dark brown.

Female terminalia. Sternite VII ( Fig. 11 ), in ventral view, slightly concave on each side of short median lobe. “Internal” sternite VIII ( Fig. 53 ), in dorsal view, with small sclerotized areas located between valvifers I. Pygofer ( Fig. 12 ), in lateral view, moderately produced posteriorly; apex triangular; with long macrosetae distributed mostly on apical 1/2, shorter dorsally. Valvifer I, in lateral view, elliptical. Valvula I ( Figs 13, 14 ), in lateral view, broadened dorsally on apical portion, narrowing gradually towards acute apex; dorsal sculptured area extending along distal 2/3 of blade, very narrow basally, formed mostly by rod-shaped elements; ventral sculptured area restricted to apical portion, formed by sparse scale-like processes; ventral interlocking device located on basal 1/3 of blade; in ventral view, basal portion of valvula I with slight outer lobe. Valvula II ( Figs 15, 16 ), in lateral view, slightly expanded beyond basal curvature, distinctly narrowed towards apex; without preapical prominence; apical portion triangular; apex narrowly rounded; dorsal margin with about 30 teeth; most teeth subtriangular or obtuse dorsally, short, with anterior and posterior portions oblique; ventroapical margin serrate; blade surface with irregular granulate sculpturing, rod-shaped apically. Gonoplac ( Fig. 17 ), in lateral view, abruptly expanded at median portion and then gradually narrowed posteriorly; apex obtuse; surface with numerous tiny denticuli apically and extending anteriorly along ventral margin, with few setae (about two or three) located apically.

Intraspecific variation. Paratypes may show the following features: crown slightly orange with irregular dark areas and absence of pair of brown spots on basal 1/2 ( Fig. 18 ); eyes silver; pronotum without anterior brown areas ( Fig. 18 ); mesonotum mostly brown or with anterior pair of light yellowish-brown spots, anteromedian area with large irregular brown macula; subgenital plate with less than four long macrosetae on median 1/3.

Etymology. The specific epithet, adenomari , is in honor of Prof. Dr. Adenomar Neves de Carvalho (Universidade Federal do Oeste do Pará, Brazil), who has greatly contributed to our knowledge of the Portanini .

Remarks. Portanus adenomari sp. nov. is similar in color pattern and morphology of the male terminalia to the following species: P. acerus DeLong, 1976 , P. bifurcus Carvalho & Cavichioli, 2017 , P. hasemani (Baker, 1923) , P. lex Kramer, 1964 , P. phoenicius Souza & Takiya, 2014 , P. pictus Carvalho & Cavichioli, 2001 , P. quadrinus DeLong, 1976 , P. uhleri Kramer, 1964 , P. xavantes Carvalho & Cavichioli, 2001 (treated as a junior synonym of P. uhleri by Carvalho (2006) in his unpublished D.Sc. thesis), and P. zacki Freytag, 2017 . They all have the crown almost uniformly brown, pronotum with numerous small pale spots, and mesonotum with anterior pair of large brown spots; forewing veins are marked with brown and white, the costal area has at least one large white macula on median portion, and the apical cells are almost entirely brown. Regarding the male terminalia, the pygofer is short and bears a small posterodorsal process, except in P. bifurcus , P. lex , and P. zacki ; the aedeagus is curved at base and bears variable apical processes. However, in the new species, the processes are very long and slender, with acute apex, and cross each other medially, being each one strongly curved posterodorsally, almost forming a complete ring ( Fig. 6 ). Unfortunately, an updated key to all species currently included in Portanus is not available.
