Biobiocoris setosus Carvalho, 1985: 253   [n. sp.]; Schuh, 1995: 83 [catalog].

DIAGNOSIS: Recognized by the uniform dark brown color (fig. 1); short and strongly transverse head (fig. 1); vestiture composed of simple bristlelike setae, and sericeous setae; genital capsule with reclined opening, located at the center, without tergal processes (fig. 3); left paramere trapezoidal, with a bifid process directed ventrally; vesica with two spicules; left spicule slightly sinuate, apically bifurcate, shorter ramus broad and denticulate, longer ramus hook-shaped; right spicule with three rami, basal and subbasal ones bifurcate, apical one simple.

DISTRIBUTION: Biobiocoris setosus   is known from Valparaíso (Region V) through Los Lagos (Region X), including the Santiago Metropolitan Region, of Chile. This is the first time B. setosus   has been recorded from Argentina, in the Neuquén Province (fig. 4).

DISCUSSION: Carvalho (1985) described the new genus and species Biobiocoris setosus   from two localities in Chile: El Abanico, Bio Bio (Region VIII), and Vegas del Flaco, Cordillera de San Fernando, O’Higgins (Region VI). Several new localities (fig. 4) and detailed illustrations of the male genitalia are here provided for B. setosus   (fig. 3). The paratype illustrated (fig. 3, AMNH_PBI 00190645) is topotypic with the holotype (cf. Carvalho, 1985: 253). The latter is deposited in the California Academy of Sciences, but was not available to me during this project.

In species of Orthotylini   the vesica protrudes from the phallotheca through its opening. Nonetheless, the basal rami of vesica’s right spicule has the longer ramus usually coming off the aedeagus through the phallobase, not through the opening of the phallotheca (e.g., AMNH_PBI 00190645) (fig. 3), although this is not the case in all specimens examined (e.g., AMNH_PBI 00103758) (fig. 3). This situation is also common in species of Lopidella   (M. D. Schwartz, personal commun.). It is not known what is causing this situation, or if having this large ramus coming through the phallobase is causing any damage to the conjunctiva.

There is also some variation regarding the curvature and serration of the basal and subbasal rami (fig. 3). This variation is found even in specimens of the same population and, therefore, is not considered species diagnostic.

I am placing Biobiocoris   in the Orthotylus species   group of Orthotylini   because of the complex, heavily sclerotized vesica (see Schuh, 1974: 278). Affinities of Biobiocoris   with other species of the Orthotylus   group are unclear. Carvalho’s decision (1985) to treat this taxon as a monotypic genus is accepted here (see also Schuh, 1995, 2006a). Future research, in particular on the phylogenetic relationships among members of the Orthotylus species   group ( Schuh, 1974), would help clarify the relationships of this taxon with other Orthotylinae   .

Carvalho (1985) compared Biobiocoris   with Melanotrichus Reuter   and Incacoris Carvalho. He   distinguished Biobiocoris   from both genera only by head characters ( Carvalho, 1985). In addition, Incacoris   has a different vesical structure ( Carvalho, 1961) and genital capsule. The aperture of the genital capsule in Incacoris   is nearly vertical and circular, displaced to the right, with a dorsal process on the far left, next to a flat vertical area, and a small, acute process above the insertion of the left paramere (personal obs.). Biobiocoris   lacks any processes on either the aperture or the dorsal surface of the genital capsule, and the aperture occupies a central position on the genital capsule. In Incacoris   , the left paramere is elongate, apically notched, with a dorsal sensory lobe ( Carvalho, 1961), and without any ventral processes as in Biobiocoris   . Because some authors consider Melanotrichus   as a synonym of Orthotylus Fieber   (e.g., Kerzhner and Schuh, 1995), further comparisons of Biobiocoris   with Melanotrichus   or Orthotylus   (s.l.) are not adequate until a comprehensive study of Orthotylus   and related groups is made on a world basis.

The ventral margin of the left paramere has a process with two prongs (fig. 3). A similar structure of the left paramere is present in some species of the New Zealand endemic genus Tridiplous ( Eyles, 2005)   , for instance T. penmani   (his fig. 63). Biobiocoris   , nonetheless, has a different vesica structure with the left spicule apically bifurcated, while in species of Tridiplous   the left spicule has a subbasal prolongation that is apically bifurcated. No known Neotropical Orthotylinae   have a left paramere with a ventral bifid process, or similar vesical structure (e.g., Carvalho, 1984, 1985; Carvalho and Costa, 1992a, 1992b).
