Lanta scotia Hebard 1921

( Figures 25–42 )

Hebard (1921) provided a good description of this species. Therefore, we complement Hebard’s description by adding features found in our specimens to help documenting intraspecific variability, and also describe male genital structures for the first time.

Material examined. Holotype (male) (ANSP- 8741) from Argentina, Córdoba Province, Córdoba (capital) (- 31.402123 °S - 64.199277 °W) (F. Schulz col). Additional specimens: ARGENTINA, 1 male, Catamarca Province, 1931 (Gomes col.), 3 males ((MACN-Ent 24036), La Paz, Córdoba Province, (- 32.217522 °S, - 65.036384 °W), 1-20 /I/ 1929 (C. Bruch. col.).

Distribution. Argentina: Córdoba Province, Córdoba (capital), La Paz; Catamarca Province; Santiago del Estero Province, Icaño, La palisa del Bracho.

Redescription (male). Habitus: body length (mm), 6.0.

Abdomen. Distal margin of supra-anal plate slightly convex ( Figs 27, 28 ).

Male genitalia. Paraprocts, distal end of L 2, L 3, and R are showed in Fig. 26 in rear view. The apodemes of the subgenital plate, and the right stylus, are all comparatively longer than those of L. borgesae ( Fig. 29 ). Left complex conformed by L 2 and L 3. L 2, which forms an acute angle with the via process, is rodlike, straight and medially placed ( Fig. 34 ), whereas L 3 is similar to that of L. borgesae ( Figs 31–33 ). Right phallomere ( Figs 35, 42 ) is conformed by R 6 ( Fig. 42 ), R 3 ( Fig. 38 ), R 1 S+R 2 ( Fig. 39 ), R 1 P ( Figs 40, 41 ) and R 4 ( Figs 36, 37 ). The right phallomere differs from the right phallomere of Lanta borgesae in some of the sclerites, R 6 has asymmetric branches of different lengths ( Fig. 42 ) and R 4 lacks a finger-likeprojection on its apex ( Fig. 37 ).
