Fonsecaiulus unciformis sp. nov.

( Figs 43–60 )

Etymology. The specific epithet, unciformis , refers to the hook-shaped apical portion of the paraphyses rami in lateral view ( Fig. 49 ).

Total length (mm). Male holotype 5.63; female paratype 5.69.

Color ( Figs 43–45 ). Dorsum brown with three longitudinal yellow stripes extending from anterior margin of crown to apex of clavus; median stripe narrowed posteriorly from median portion of pronotum, continuing as narrow line along commissural margins; lateral stripes strongly narrowed on median portion of clavus. Corium with irregular yellow stripe extending from anterior portion of brachial cell to inner anteapical cell, strongly narrowed along anterior third; very narrow yellow stripe extending longitudinally near costal margin, posteriorly connected to yellow macula on median and outer anteapical cells.

Male terminalia. Pygofer ( Fig. 46 ), in lateral view, moderately produced posteriorly; posterior margin broadly rounded; without processes; sparse macrosetae of distinct sizes distributed mostly on posterior portion and extending anteriorly over ventral portion. Valve ( Fig. 47 ), in ventral view, short and broad, subrectangular; anterior margin concave. Subgenital plate ( Figs 46, 47 ), in ventral view, with basal half broad and apical half narrow, outer margin rounded at basal half; plate fused along basal third to its counterpart; without macrosetae; in dorsal view, with two tiny dentiform processes at apical portion of basal half, not located close to each other, anterior process associated with style apex; in lateral view, plate not extending as far posteriorly as pygofer apex. Connective ( Fig. 48 ), in dorsal view, subquadrate, without stalk, with slight median keel. Style ( Fig. 48 ), in dorsal view, extending farther posteriorly than connective; apophysis without preapical lobe; apical portion strongly narrowed, bearing setae; apex truncate, foot-shaped. Aedeagus ( Figs 49, 50 ) symmetrical; shaft, in lateral view, elongate, subcylindrical, curved dorsally, with acute apex; without processes; gonopore located ventrally at apical third. Paraphyses ( Figs 49, 50 ), in lateral view, with elongate rami, each one with ventral subquadrate lobe at median portion and with apex curved ventrally, hook-shaped.

Female terminalia. Sternite VII ( Figs 51–53 ), in ventral view, with posterior margin trilobed; median lobe broad, subquadrate. “Internal” sternite VIII without distinct sclerites. First valvifer ( Figs 54, 55 ), in lateral view, somewhat trapezoidal; anterior portion with sclerotized bifurcated structure with short dorsal and long ventral branch associated with first valvula (indicated by an arrow in Fig. 54 and magnified in Fig. 55 ); surface of this structure distinctly covered by tegumentary processes. First valvula ( Figs 54, 56 ), second valvula ( Figs 57–59 ), and gonoplac ( Fig. 60 ) much as described for F. spinosus sp. nov. Second valvula with about 22 teeth.

Type material. Holotype: male, “ Brasil, Minas Gerais, \ São Roque P. N. [Parque Nacional] Serra \ da Canastra \ 14–19.xii.2013 Malaise \ Melo & Rosa legs.” ( DZUP) . Paratypes: one female, same data as the holotype ( DZUP) ; one female, “BRA [ Brazil], MG [Minas Gerais], Serra do Salitre, \ RPPN [Reserva Particular do Patrimônio Natural] Cachoeira do Campo \ (19º09′45,7”S / 46º34′01,9”W, \ alt. 1063m) 11–15.X.2012 \ Lima & Kumagai col.” ( DZUP) .

Remarks. Males of F. unciformis sp. nov. can be recognized by the subquadrate lobe at the median portion and the hook-shaped apex of the paraphyses rami ( Figs 49, 50 ). In females, the posterior margin of the sternite VII is characteristically trilobed ( Fig. 53 ) and, as aforementioned, a peculiar bifurcate structure is associated with the first valvifer and valvula of the ovipositor ( Figs 54, 55 ).
