E-mail: cecimelo@ilpla.edu.arMaría Cecilia MeloOn the taxonomic placement of the genus Sinnamarynus (Hemiptera: Heteroptera: Reduviidae), and a new record of S. rasahusoides from PeruThe genus Sinnamarynus was established by Maldonado Capriles and Bérenger (Bérenger et al. 1996) to include the newly described species S. rasahusoides. The authors placed the genus into the subfamily Reduviinae with no arguments. They mentioned the remarkable similarity of S. rasahusoides with the sympatric peiratine species Rasahus sulcicollis (Serville, 1831), and referred to other cases of sympatric species of similar appearance, but did not discuss the characters that make the similarity so remarkable.Reduviinae contains approximately 140 genera and about 980 species and shows a worldwide distribution (Maldonado Capriles 1990; Ishikawa et al. 2005). The subfamily cannot be characterized by synapomorphies, but it is defined mainly by the absence of apomorphies occurring in other reduviid subgroups (Schuh and Slater 1995). A recent phylogenetic analysis presented by Weirauch (2008) demonstrated its polyphyletic nature; in contrast, the monophyly of subfamily Peiratinae is well supported by the following characters: presence of a row of sensillar pits on maxillary apex; presence of lobe-like processes on ventral gap of left maxillary stylet; enlarged protibial fossula spongiosa; asymmetric male genitalia; presence of a median guiding structure on valvifer 1 and valvula 1; and presence of a bulbous structure on valvula 2. Aside from the material mentioned in the description of S. rasahusoides, deposited at Muséum National d’Histoire Naturelle, Paris, France (MNHN), no other specimens have been found so far. The genus with its single included species has only been known from French Guiana. Studying the entomological collection of the Museo de Ciencias Naturales de La Plata, Buenos Aires, Argentina (MLP), a new male was found from Peru. After studying the holotype and the Peruvian specimen it was concluded that the genus should be placed into the subfamily Peiratinae. The characters supporting this decision are described and illustrated in the present paper. Sinnamarynus Maldonado Capriles and Bérenger, 1996Sinnamarynus Maldonado Capriles and Bérenger, 1996: 251, 255. Type species by original designation: S. rasahu-soides Maldonado Capriles and Bérenger, 1996: 252.Sinnamarynus: Forero, 2004: 161 (diagnosis, distribution), 188 (in key).Sinnamarynus: Gil Santana and Coletto Silva, 2005: 297–298 (in key).Diagnosis: Small size, and robust. Head short, anteocular region short; preocellar transverse groove deeply impressed; antenna thick, scapus curved, relative antennal segment length II>III=IV>I; eyes globose and protruding; rostrum robust, second segment the longest; anterior lobe of pronotum quadrangular, longer than posterior lobe, humeral angles rounded; metapleural suture straight; femora incrassate, ventral surface with strong protuberances bearing a stiff setae at apex; fossulae spongiosa present on anterior and middle tibiae; corium elongate, covering ¾ of abdomen; abdominal venter flattened; male genitalia asymmetrical (figs. 2–8): posterior process of pygophore bent laterally to the right (figs. 3–4), left paramere enlarged (figs. 5–6)Discussion: The examination of the material and the photographs of the male holotype, confirm that this species should be included in the subfamily Peiratinae and not within Reduviinae. Following the phylogenetic analysis of Weirauch (2008), the characters found in Sinnamarynus rasahusoides that support this placement are: the elongate anterior lobe of foretibial fossula spongiosa, and the asymmetry of the male genitalia (figs. 2–8); other characters, such as those related to the mouthparts and to the female genitalia were not examined owing to the scarcity of material and the destructiveness of the approach. The female of this species remains unknown. The subfamily Peiratinae is represented in the Western 541Melo | Taxonomy and a new record of SinnamarynusAcknowledgments: I am grateful to Sara I.
