Fonsecaiulus truncatus sp. nov.

( Figs 97–114 )

Etymology. The specific epithet, truncatus , refers to the shape of the posterior margin of the male pygofer in lateral view ( Fig. 100 ).

Total length (mm). Male holotype 5.38; male paratypes 5.13–5.75 (n = 4); female paratypes 5.44–5.63 (n = 3).

Color ( Figs 97–99 ). Dorsum brown with three longitudinal pale yellow stripes extending from anterior margin of crown to posterior margin of mesonotum; median stripe narrowed between pronotum and mesonotum; lateral stripes very narrowed; commissural margin, veins of clavus, and claval sulcus almost entirely pale yellow. Corium with some longitudinal veins partially pale yellow; two pale yellow maculae, one adjacent to median portion of claval sulcus and another on inner anteapical cell.

Male terminalia.Pygofer ( Fig. 100 ), in lateral view, slightly produced posteriorly; posterior margin truncate, with inner fold; without processes; sparse macrosetae of distinct sizes distributed mostly on posterior half, except dorsally. Valve ( Fig. 101 ), in ventral view, short and broad, subrectangular; anterior margin slightly concave. Subgenital plate ( Figs 100, 101 ), in ventral view, with basal third broad, pronounced, and with outer margin rounded; plate fused along basal half to its counterpart; without macrosetae; in dorsal view, with two strong dentiform processes at apical portion of basal third, not located close to each other, anterior process associated with style apex; in lateral view, plate extending almost as far posteriorly as pygofer apex. Connective ( Fig. 102 ), in dorsal view, forming transverse bar, with small stalk, slightly curved posteriorly, with dorsal median keel. Style ( Fig. 102 ), in dorsal view, short but extending farther posteriorly than connective; apophysis with conspicuous, pronounced preapical lobe; portion behind lobe strongly narrowed, bearing setae; apex tapered. Aedeagus ( Figs 103, 104 ) symmetrical; shaft, in lateral view, elongate, expanded apically, with pair of basiventral, acute elongate processes, extending posteriorly slightly beyond pygofer apex; gonopore located ventrally at apical third. Paraphyses absent.

Female terminalia. Sternite VII ( Figs 105–107 ), in ventral view, with posterior margin, in unmacerated specimens, slightly emarginate, median portion with pair of slight concavities on each side of small median dentiform projection; posterior margin, in macerated specimens, triangularly produced. “Internal” sternite VIII, in dorsal view, with sclerotized areas, including broad anterior sclerite and rounded posterior sclerite (indicated by arrows in Fig. 109 ). First valvifer ( Fig. 108 ), in lateral view, subrectangular. First valvula ( Figs 108, 110 ), second valvula ( Figs 111–113 ), and gonoplac ( Fig. 114 ) much as described for F. spinosus sp. nov. Second valvula with about 30 teeth.

Remarks. Fonsecaiulus truncatus sp. nov. is our third new species that has no paraphyses. It can also be distinguished from other species of the genus by the truncate posterior margin of the pygofer ( Fig. 100 ), pronounced basal portion of the subgenital plates ( Fig. 101 ), and aedeagus expanded apically, bearing an elongate pair of basiventral processes ( Figs 103, 104 ). The female sternite VII has a median dentiform projection ( Figs 105–107 ) and the “internal” sternite VIII, in dorsal view, has a large anterior sclerite ( Fig. 109 ).
