Habralebra gillettei Young, 1957

( Figs 4–6 , 30–37 )

Total length 3.5–3.6mm. General color milky white with brown spots; eyes and ocelli light brown. Head with anterior margin produced and angled medially; pronotum approximately twice length of crown, margins of laterobasal angles exceeding width of head; scutellum with brown spot.

Forewing ( Figs 4 , 30 ) milky white, basal margin of clavus with brown spot continuous with scutellar spot; small brown round spot near costal margin on basal third; brown spot on apex of cell cup, continuous with apical region of brachial cell, appendix and base of apical cells; transversal and MP2 veins aligned; vein ScP+RA indistinct. Hind wing ( Fig. 31 ) with submarginal vein confluent with apical margin anteriorly to apex of vein MP2+CuA1; vein CuA2 distinct from a point very close to vein MP2; vein CuP confluent with submarginal vein more basally than vein MP2.

Subgenital plate ( Fig. 33 ) long, gradually tapering to apex; apex round; with internal folds from base to median third; apical third with external folds giving twisted aspect to apex; median third with five macrosetae distributed longitudinally, two basal most sided, each one, by small and stout seta; many long filiform setae following external margin from near basal margin to apex, where setae of various sizes can be found. Pygofer ( Fig. 32 ), in lateral view, with internal and external folds, dorsal and ventral; internal process long with apex thin and twisted, extended ventrad; with five macrosetae, one near dorsal margin just basad of internal process and four on disc near midlength arranged transversally and, anteriorly to them, pair of filiform and short setae; group of filiform long setae on anteroventral region. Stylus ( Figs 34, 35 ) with distinct round preapical lobe, anterior branch curved with broad and trucate apex, with short spiniform projection. Connective ( Fig. 36 ) V-shaped. Aedeagus ( Figs 36, 37 ) compressed; preatrium narrow and long; dorsal apodeme short, similar in shape to robust “T”, in ventral view; stem long, sinuous, cylindrical with numerous small tubercles more concentrated on dorsobasal region, apex narrow and truncate; gonopore dorsoapical; base broad, bearing single ventral process, as long as stem, cylindrical and with sharp apex.

Examined material: Mata do Paraíso, Viçosa, Minas Gerais, Brasil, P.S.F. Ferreira leg. 3 male specimens: (23/ix/1981); (14/x/1981); (24/ii/1982) (MEUV).

Comments. The most evident differences in relation to previous descriptions of Habralebra gillettei (Young 1957b, Dworakowska 1994) are the number of macrosetae, the presence of filiform setae at the base of the pygofer and the thinner apex of the style. H. gillettei , here recorded for the first time from Minas Gerais State, differs from the other species of the genus by having the apex of the style broadened and by the shape of the aedeagus.
