Valvula II ( Figs 15, 16 View FIGURES 11–21 ), 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 View FIGURES 11–21 ), 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 View FIGURES 11–21 ); eyes silver; pronotum without anterior brown areas ( Fig. 18 View FIGURES 11–21 ); 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1964 , P. xavantes Carvalho & Cavichioli, 2001 (treated as a junior synonym of P. uhleri by Carvalho (2006) in his unpublished D.Sc.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 View FIGURES 1–10 ). Unfortunately, an updated key to all species currently included in Portanus is not available.
