Plumarius tumidulus Papp, 2000: 157 –160  , figs 1–8 [holotype, ♂, Argentina, Tucumán (Hungarian Natural History Museum)].

Diagnosis. This species is characterized by the scape basally with a ventral, rounded projection, and its moderate ocelli, the anterior one above the supra-torular line.

Redescription. Body length 5.7–7.5 mm. Color. Light brown, head darker.

Head. Wider in dorsal view than width of scutum between tegulae; vertex with weak sculpture, reticulated, moderately punctate. Torulus closer to lateral ocellus than to clypeus. Lateral ocelli in frontal view below upper margin of head. Median ocellus above supra-torular line ( Fig. 14View FIGURE 14 A). Genal carina weak, distinct. Length of area between preoccipital carina and suboral swelling subequal to length of suboral swelling (0.7: 0.8); without median, longitudinal carina; low area of genal bridge close to mandibular articulation without carinae or punctures ( Fig 14View FIGURE 14 B). Malar area subequal to apical width of F 1, with striae anteriorly. Supraclypeal area with lateral striae; flattened in lateral view. Epistomal suture evident. Clypeus 1.3 × wider than high, with lateral striae; apical margin rounded; weakly rounded in lateral view ( Fig. 14View FIGURE 14 C). Scape basally with ventral, rounded projection. F 1 4.6 × as long as its apical width, shorter than scape and pedicel combined (2.1: 2.3).

Mesosoma  . Area anterior to pronotal lobe smooth; pronotal lateral carina distinct, forming lower pocket. Notaulus weakly marked, as long as admedian line. Anterior surface of scutum without punctures. Propleuron and mesopleuron densely punctate. Metaposnotum with striae reaching posterior margen. Propodeum transverse; swollen behind spiracle, without carina anterior to spiracle. Fore wing: marginal cell with anterior margin 3.9 × as long as posterior margin; veins Rs 3 shorter than Rs 4 (1.7:2.0); discal cell rectangular. Protarsomere 1 with five lateral spines. Length of mesotarsomere 1 shorter than metatarsomere 1 (4.0: 5.8); inner metatibial spur 0.1 × as long as outer spur.

Metasoma. T 7 triangular. Genitalia as in Fig. 14View FIGURE 14 D.
