Belostoma dallasi De Carlo, 1930 View in CoL

( Figs 6M–P View FIGURE 6 ; 17D View FIGURE 17 ; 23A View FIGURE 23 )

Zaitha anurus: Berg 1879 (probably in part): 192.

Belostoma boscii: Kirkaldy & Torre-Bueno 1909 View in CoL (in part): 190.

Belostoma dallasi De Carlo, 1930: 114 View in CoL , plate V ( Fig. 12 View FIGURE 12 ).

Belostoma bosci: De Carlo 1960 (according to Lauck 1962): 54, 57 ( Figs 21 View FIGURE 21 –26).

Types.—According to De Carlo (1930), Lauck (1962), and Schnack (1976), B. dallasi View in CoL was described based on a male holotype and a female paratype [locality not mentioned] deposited in MLPA, and on paratypes (Salta Province, Argentina) in MACN, and Lizer’s and Trelles’ collections. These specimens have not been examined.

Material examined.— BRAZIL. Ceará — * 1 m ( DPIC): Praia de Lagoinha , 07.VII.1999, (M. H. Pereira), A. L. Melo det. 1999. Minas Gerais — * 1 m ( DPIC 1821 View Materials ): Itacambira, Peruaçu River , 24.XI.1997, (A. L. Melo), N. Nieser det.

Distribution.— ARGENTINA: Salta ( De Carlo 1930). BRAZIL ( De Carlo 1960): Ceará (new record), Goiás ( Menke & Lauck 1962), Minas Gerais ( Nieser & Melo 1997). MÉXICO ( De Carlo 1960).

Description.—Measurements (m / f). Total length (from apex of head to apex of hemelytra at rest) 31.8– 34.6; largest width of body 13.8–14.5; median length of pronotum 5.43–6.00; greatest pronotal width 9.86– 10.71.

General coloration brown.

Body relatively slender. Length of anteoculus 0.91–0.97 times length of interoculus; length of rostral segment I 1.20–1.29 times length of segment II; anterior frontogenal suture equal to or longer than posterior frontogenal suture; clypeus reaching ocular line or not (0–0.21 mm); vertex without longitudinal median carina; posterior interocular width 1.15–1.29 times length of anteoculus, and 1.33–1.39 times width of eye; eyes rounded. Pronotum without longitudinal median carina; greatest pronotal width 1.79–1.82 times its length; scutellum reaching nodal line, with weakly longitudinal median carina posteriorly; prosternal keel prominent, slightly triangular, rounded at apex ( Fig. 6M View FIGURE 6 ). Pilosity not extending along genital operculum, covering part of connexivum.

Male genitalia ( Fig. 6N–P View FIGURE 6 ).—Dorsal arms short, converging, narrowed apically in dorsal view; ventral diverticulum with dorsal caudal protuberance in dorsal and lateral views, and with developed ventroapical protuberance in lateral and ventral views; caudal lateral margins of ventral diverticulum convex, not sinuous in ventral view; width of ventral diverticulum 1.3 times its length in ventral view.

Comparative notes.—According to Nieser and Melo (1997), B. dallasi differs from B. anurum because in the latter the anteoculus is longer than the interoculus. Moreover, the width of the ventral diverticulum of B. anurum is twice its length in ventral view.
