(Figs 3 A–D)
Diagnosis. This species is characterized by the presence of a specialized setose area on the under surface of the metacoxa. It is distinguished from the other five species with a setose coxa by the weakly rounded clypeal and supraclypeal areas, the simple scape, the short palpi and the ocelli not reaching the top of the head.
Description. Holotype, ♂. Body length 5.3 mm (paratype 5.1). Color. Brown, with head darker.
Head. 1.2 × wider than high in frontal view; wider in dorsal view than width of scutum between tegulae (7.1:6.2). OOD 1.3 × diameter of lateral ocellus; POD 1.4 × OOD. Antennocular distance 1 × diameter of torulus; interantennal distance 2.2 × antennocular distance. Vertex finely reticulated, without striae or punctures between lateral ocelli. Torulus closer to lateral ocellus than to clypeus (1.5:2.1). Lateral ocelli in frontal view below upper margin of head. Median ocellus crossed by supra-torular line (Fig. 3 A). Genal carina distinct. Length of area between preoccipital carina and suboral swelling subequal to length of suboral swelling (1.2:1.1); this area without median longitudinal carina; lower area of genal bridge close to mandibular articulation with weak carinae (Fig. 3 B). Malar area subequal to apical width of F1 (0.7:0.6), striate anteriorly. Supraclypeal area with weak lateral striae; in lateral view weakly rounded (Fig. 3 C). Epistomal suture evident. Clypeus 1.4 × wider than high, with weak lateral striae; in lateral view weakly rounded. Proportion of lengths of segments of maxillary palp, from base to apex: 11:0.8:14:15:15:16. Scape without swelling or projection. F1 6.1 × as long as its apical width, longer than scape and pedicel combined (3.7:3.3).
Mesosoma. Area anterior to pronotal lobe smooth; pronotal lateral carina distinct, not forming lower pocket. Notaulus weakly marked, as long as admedian line. Anterior surface of scutum scarcely punctate about notaulus. Propleuron and mesopleuron scarcely punctate. Metapostnotum with striae reaching to posterior margin. Propodeum transverse, not swollen behind spiracle; without carina anterior to spiracle. Fore wing: marginal cell with anterior margin 2.1 × as long as posterior margin; vein Rs3 longer than length of Rs4 (3.1:2.6); vein M separated from vein cu-a by 0.4 × length of cu-a; discal cell rectangular. Hind wing: veins M and cu-a interstitial. Protarsomere 1 with three outer lateral spines. Length of mesotarsomere 1 shorter than metatarsomere 1 (3.6:5.5); inner metatibial spur 1.3 × as long as outer spur.
Metasoma. T7 pointed apically. Genitalia as in Fig. 3 D.
Examined material. Holotype, ♂: ARGENTINA, La Rioja: Ruta 141, km 104 ca. de Marayes, 29.I.2006, col Fidalgo P. (MACN). Paratype: 1♂, same data of holotype (MACN).
Distribution. Argentina (La Rioja).
Etymology. The specific epithet, sarophorus, is a Latin adjective referring to the presence of a specialized, setose area on the metacoxa.
