description: Dikrella (Dikrella) reticulata, sp.nov.
(Figs 6–8, 21–28)
Total length 3.0–3.2 mm. General color varying from light-yellow to ochraceus, eyes brown. Median length of crown longer than interocular width on base; crown with spots on basal half, contiguous to those of pronotum, forming bands; one median white band on coronal suture, and a red band on each side; front little long than wide; pronotum approximately three times longer than crown length, margin of laterobasal angles not exceeding width of head; anterior margin with white spots, irregular, immediately behind each eye. Forewing with smoked areas on apex of cell cup and apical cells; vein ScP+RA marked along half of its extension by brown spot and vein MP 2 +CuA 1 with small brown spot near base; apical cell I distinctly wider than apical cells II and III, these wider on apex than on base; apical cell II thinner than others; apical cell IV quadrangular. Hind wing with vein CuA 2 originating from point slightly more basal than MP 2; vein CuP confluent with submarginal vein more basally than bifurcation of CuA.
Subgenital plate with margins convergent from basal third to twisted apex; external margin with scattered small and delicate setae; central region of basal half bearing longitudinal series of four macrosetae; apical half with surface irregularly rugose. Pygofer long, with posterior margin sharpened into lobe tapered on apex bearing concentrated group of small robust setae; dorsal margin with external process gradually tapering to apex, not reaching apex of pygofer. Stylus long, with long filiform biseriate setae on preapical lobe and, uniseriate on apical region; apex thin, slightly curved upward. Connective T-shaped, with subterminal articulation with stem of aedeagus; main stem shorter than lateral arms. Aedeagus with well developed atrial complex, with pair of long and robust processes, arising on preatrial anterior region, with fused bases; apical half of processes with ridges forming irregular reticulum; aedeagal stem proportionally short, apical region abruptly compressed laterally, forming ventroapical keel; gonopore apical. Female unknown.
Etymology. The species epithet, reticulata, refers to the texture of the aedeagal processes.
Type material. Male holotype: Mata do Paraíso, Viçosa, Minas Gerais, Brasil, 14/ix/1986, P.S.F. Ferreira leg. (DZRJ). Paratypes (males): same locality and collector as holotype, 1 specimen (23/ix/1986) (DZRJ), 1 specimen (22/x/1986) (MEUV).
Comments. The pygofer form and the form and position of the pygofer process in the new species (fig. 24) are similar to D. venella Ruppel and DeLong, although the latter belongs to the subgenus Readionia. Dikrella (Dikrella) reticulata sp. nov. can be distinguished from the other species of the genus mainly by the aedeagus form (Figs 27, 28), with the preatrial region well developed, the pair of preatrial processes positioned away from the aedeagus stem, and by the T-shaped connective (Fig. 27), with subterminal articulation with the aedeagal stem.
