Capsus (Deraeocoris) fratruelis Berg, 1879: 289 [n. sp.].

Deraeocoris fratruelis: Carvalho, 1957: 65 [new status, catalog].

Hyporhinocoris fratruelis: Carvalho and Carpintero, 1992: 91 [n. comb.]; Schuh, 1995: 123 [catalog].

Hyporhinocoris tomentosus Reuter, 1909: 18 [n. gen., n. sp.]; Carvalho, 1958 [catalog]; Carvalho and Afonso, 1977: 9 [list]; Schuh, 1995: 123 [catalog]. NEW SYNONYM.

DIAGNOSIS: Recognized by the labium inserted posteriorly on the head, resulting in a very short gula (figs. 11A, C); dorsum covered with simple decumbent setae and dense sericeous setae (fig. 12B); strong sexual dimorphism, males with large protruding eyes (figs. 1A, B, 11A, B) and elongate body shape (fig. 1A, B), females with smaller eyes (figs. 1C, D, 11C, D) and ovoid body shape (fig. 1C, D); genital capsule of male with a medial, ventral, flattened prolongation, apically directed to the left (figs. 11E; F, arrow; 13, white arrows); left paramere compressed dorsoventrally, apex with a small process directed ventrally, sensory lobe short and blunt, directed caudad (fig. 13, arrow); right paramere ovoid, shorter than left paramere, wide basally, apex as a small round process (fig. 13); phallotheca cylindrical, its opening nearly vertical, in posterior view with margins sinuate (figs. 11E, F, 13); vesica with two spicules, right one curved medially and with numerous apical spines, left one apically bifurcated (fig. 13); secondary gonopore opening ventrally slightly to the right (fig. 13).

Hyporhinocoris fratruelis is easily distinguished from other Neotropical Orthotylini by its strong sexual dimorphism (fig. 1A–D), and by the structure of the male genitalia.

DISTRIBUTION: Hyporhinocoris fratruelis is known only from Argentina, occurring mostly on the Monte Desert (fig. 4). The distribution of H. fratruelis closely follows those of its hosts (see Ezcurra et al., 1991: fig. 3).

HOSTS: Hyporhinocoris fratruelis is associated with Larrea divaricata Cav. and L. cuneifolia Cav. (Zygophyllaceae) .

DISCUSSION: Berg (1879) described Capsus (Deraeocoris) fratruelis based on two specimens from ‘‘Rio Colorado’’ in the southern part of the Buenos Aires Province. Reuter (1909) described the new genus and species Hyporhinocoris tomentosus from an undetermined locality in Argentina, and placed it in the Orthotylinae . Capsus fratruelis was placed in Deraeocorinae by Carvalho (1957), but the structure of the mesothoracic spiracle, evaporatory area (fig. 12A), parempodia (fig. 12C, D), and male genitalia (fig. 13) clearly place this taxon in the Orthotylinae (e.g., Reuter, 1909; Carvalho and Carpintero, 1992).

Carvalho and Carpintero (1992) transferred Capsus fratruelis Berg , placed until then in Deraeocorinae , to Hyporhinocoris and designated a female neotype from Santa Fé Province. They failed, however, to discuss their action and to compare H. fratruelis with H. tomentosus , considering the two as valid species.

Variation may be found in coloration and hemelytral length (fig. 1A–D), even in specimens collected at the same locality at the same time (e.g., AMNH_PBI 00107379–AMNH_ PBI 00107380, AMNH_PBI 00189457–AMNH_ PBI 00189461, AMNH_PBI 00194846–AMNH_

PBI 00194847, AMNH_PBI 00194875– AMNH_ PBI 00194876). Despite this variation, dissection and study of several specimens from the recent PBI fieldwork and from museum collections demonstrated that male and female genitalic structures are uniform across the geographic range of this species, even between host plants. Because the examined specimens of different color variants, from across the geographic range, and from different host plants, which did not exhibit any male or female genitalic differences, I consider that Capsus fratruelis represents the same species as Hyporhinocoris tomentosus .
