Plumarius mikrommatus Diez & Roig-Alsina , sp. nov.
( Figs 16 View FIGURE 16 A–D)
Diagnosis. This species falls in a group with the anterior ocellus above the supra-torular line and the marginal cell with the anterior margin long and a narrowed apex. It is related to P. obscurus sp. nov., from which it differs by the size of the ocelli, very small and with an OOD 2.7–3.0 × their diameter.
Description. Holotype, ♂. Body lenght 5.4 mm. (paratypes 4.1–7.5 mm). Color. Dark brown, almost black, with following parts lighter: scape and pedicel, apical area of F1, apex of clypeus, mandibles, legs and metasoma.
Head. 1.0 × wider than long in frontal view; width in dorsal view subequal to width of scutum between tegulae (2.2:2.5). OOD 3 × diameter of lateral ocellus; POD 5 × OOD. Antennocular distance 1.1 × diameter of torulus; interantennal distance 2.6 × antennocular distance. Vertex smooth. Torulus closer to lateral ocellus than to clypeus (1.2:2.0). Lateral ocellus, in frontal view below upper margin of head. Median ocellus above supra-torular line ( Fig. 16 View FIGURE 16 A). Genal carina present, distinct. Length of area between occipital carina and suboral swelling subequal to length of swelling (1.2:1.1); without median, longitudinal carina; low area of genal bridge close to mandibular articulation without carinae or punctures ( Fig. 16 View FIGURE 16 B). Malar area longer than apical width of F1 (1.2:0.8), striate anteriorly. Supraclypeal area with lateral striae; convex in lateral view ( Fig. 16 View FIGURE 16 C). Epistomal suture distinct. Clypeus 1.3 × wider than long, with lateral striae, rounded in lateral view; apically not truncate. Proportion of segments of maxillary palp from base to apex: 10:12:14:15:13:10. Scape without swelling or projection. F1 5.6 × longer than its apical width, subequal to scape and pedicel combined (4.5:4.3).
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. Propleuron and mesopleuron without punctures. Metaposnotum with longitudinal striae, not reaching posterior margin in the central area. Propodeum transverse; swollen behind spiracle, without carina anterior to spiracle. Fore wing: marginal cell with anterior margin 2.4 × longer than posterior margin; vein Rs3 longer than Rs4 (3.9:1.6); vein M separated from cu-a by 2.7 × length cu-a; medial cell rectangular. Protarsomere 1with two outer lateral spines. Length of mesotarsomere 1 shorter than metatarsomere 1 (3.9:5.7); inner metatibial spur 1.6 × as long as outer spur.
Metasoma. T7 triangular, apically pointed. Genitalia as in Fig. 16 View FIGURE 16 D.
Examined material. Holotype, ♂: ARGENTINA, Salta, 1 ♂, Iruya, 23.IX.2009, col. Fidalgo P. ( MACN). The following are paratypes: 13 ♂, same data of holotype (6 ♂ MACN, 4 ♂ IFML, 3 ♂ MLP). Jujuy, 1 ♂, Hornillos, 17.I.2011, col Diez, Garlati ( MACN); 3 ♂, Hornillos, 23º39´43ʹʹS, 65º26´32ʹʹW, 24.II.2015, col Diez, Garlati ( MACN in alcohol).
Distribucion. Argentina (Salta, Jujuy).
Etymology. The specific epithet, from the Greek, mikros: small and omma: eye, refers to the small ocelli.
