Fonsecaiulus truncatus sp. nov.

( Figs 97–114 View FIGURES 97–104 View FIGURES 105–114 )

Etymology. The specific epithet, truncatus , refers to the shape of the posterior margin of the male pygofer in lateral view ( Fig. 100 View FIGURES 97–104 ).

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 View FIGURES 97–104 ). 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 View FIGURES 97–104 ), 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 View FIGURES 97–104 ), in ventral view, short and broad, subrectangular; anterior margin slightly concave. Subgenital plate ( Figs 100, 101 View FIGURES 97–104 ), 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 View FIGURES 97–104 ), in dorsal view, forming transverse bar, with small stalk, slightly curved posteriorly, with dorsal median keel. Style ( Fig. 102 View FIGURES 97–104 ), 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 View FIGURES 97–104 ) 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 View FIGURES 105–114 ), 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 View FIGURES 105–114 ). First valvifer ( Fig. 108 View FIGURES 105–114 ), in lateral view, subrectangular. First valvula ( Figs 108, 110 View FIGURES 105–114 ), second valvula ( Figs 111–113 View FIGURES 105–114 ), and gonoplac ( Fig. 114 View FIGURES 105–114 ) 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 View FIGURES 97–104 ), pronounced basal portion of the subgenital plates ( Fig. 101 View FIGURES 97–104 ), and aedeagus expanded apically, bearing an elongate pair of basiventral processes ( Figs 103, 104 View FIGURES 97–104 ). The female sternite VII has a median dentiform projection ( Figs 105–107 View FIGURES 105–114 ) and the “internal” sternite VIII, in dorsal view, has a large anterior sclerite ( Fig. 109 View FIGURES 105–114 ).
