Exogonia hyalinosparsa

Exogonia hyalinosparsa (Melichar, 1932) (Figs 66–79) Length: males, 7.6-9.5 mm; females, 7.5-10.4 mm. External morphology. Head (Figs 66–69), in dorsal view, moderately produced anteriorly, anterior margin rounded; crown with median length 1/2 to 3/5 interocular width and 1/3 transocular width; surface of crown with pair of distinct foveae externally to ocelli; epicranial, temporal, and frontogenal sutures distinct. Pronotum (Figs 66–69), in dorsal view, with width approximately equal to transocular width. Forewings (Fig. 66) with membrane distinct on apical portion, including apical cells. Color. Ground color of dorsum brown to dark brown, with three distinct patterns of yellow or yellowishwhite markings (Figs 66–69): (1) with pair of longitudinal stripes extending from frontogenal sutures to apical portion of forewings (Fig. 66), convergent anteriorly on pronotum (Fig. 68), and with small irregular maculae on crown and along costal margin, other small marks may be present; (2) with numerous, irregular small marks (Fig. 69); (3) with this same small marks, usually in a smaller number (Fig. 67), and with large maculae, a pair on pronotum (sometimes absent) and three or four on forewings, one on basal portion of clavus, one on basal portion of discal cells (sometimes absent), and two near apex of clavus, one anteriorly and other posteriorly. Frons brown with broad macula medially and small maculae on muscle impressions and at transition to crown, yellow; genae and lora mostly pale yellow with brown marks; clypeus almost entirely dark brown. Proepisternum yellow. Lateral pronotal lobes dark brown. Venter brown to dark brown; legs pale yellow (four specimens from Espírito Santo State with face and venter yellow to dark yellow with pale brown maculae). Male genitalia. Pygofer (Fig. 70), in lateral view, with macrosetae on apical portion and extending anteriorly along ventral margin; apical portion with inner process bearing numerous setae (absent in two males from Espírito Santo State). Subgenital plates (Fig. 71), in ventral view, strongly narrowed toward apex on basal portion; with row of short macrosetae near outer margin and some microsetae along outer margin. Styles (Fig. 72), in dorsal view, short, extending posteriorly slightly beyond apex of connective; with distinct preapical lobes on inner and outer margins; apical portion beyond outer lobe curved and with few setae; apex truncate. Connective (Fig. 72), in dorsal view, T-shaped; stalk short, broad. Aedeagus (Fig. 73) with shaft, in lateral view, directed dorsally and expanding gradually toward apex, dorsal margin serrate. Paraphyses (Figs 74, 75), in dorsal view, with posterior pair of rami longer, more sclerotized than anterior one, with apex, in lateral view, truncate, serrate and curved ventrally; stalk approximately as long as posterior rami. Anal tube (segment X) without processes or areas bearing small setae. Female genitalia. Sternite VII (Figs 76, 77) longer than broad; lateral margins convergent posteriorly; apical portion slightly transversely striate, with short sparse setae; apex pronounced with three small lobes (much more pronounced and without lobes in specimens from Espírito Santo State, Fig. 77), median lobe shorter than lateral ones. Pygofer (Fig. 78) as in E. flavomaculata. Second valvulae (Fig. 79), in lateral view, with shaft narrowing toward subacute apex; preapical prominence absent or only slightly developed; basal teeth large and rectangular (the first three may be small and triangular in specimens from Espírito Santo State), followed by gradually smaller ones. Other features of second valvulae as in E. flavomaculata. Material examined. Brazil: Espírito Santo, Rio de Janeiro, São Paulo, Paraná, and Santa Catarina states. One female, “ESP.
