Eumenes pius pius Giordani Soika 1986

(Figs 8, 9, 15)

Material examined. TIMOR I.: 2 Ƥ (MZB), Camplong, Kupang, Pollen NTT, Sudarman H.K., 21 Feb.1985. KOMODO I.: 1 Ƥ (MZB), Pulau Komodo, S. Kadarsan, 1 Nov.1961.

Redescription. FEMALE. Body length 13.5–14.5 mm; fore wing length 9.5– 10 mm. Head in frontal view subcircular, 1.2 × wider than high. Clypeus in lateral view weakly convex, with anterior margin smoothly curved ( Fig. 15 ); in frontal view 1.2 × as high as wide, with dorsal and ventral margins both deeply emarginate medially (Fig. 9). Labrum broadly rounded apically. Mandible with dorsalmost tooth short and blunt. Antennal scape 3.5 × as long as its maximum width; flagellomere 1 2.4 × as long as wide.

Mesosoma globular ( Fig. 15 ), 1.1 × as long as high in lateral view, slightly longer than wide in dorsal view. Pronotal carina strongly produced anteriorly at humeral angle, slightly weaker dorsally. Mesoscutum in lateral view weakly convex, smoothly curved dorsally, in dorsal view as long as wide. Tegula convex. Scutellum convex, with median longitudinal depression. Metanotum nearly flat. Propodeum moderately convex; posterior face in lateral view smoothly curved ( Fig. 15 ); median longitudinal groove very shallow; posterior face barely depressed medially in dorsal half, more or less distinctly depressed medially in ventral half.

Metasomal segment 1 long and slender, in lateral view slightly swollen dorsally, nearly 1.25 × as long as mesosoma length ( Fig. 15 ); tergum in dorsal view swollen posteriorly in basal half, then nearly parallel-sided, slightly constricted subapically, with apical width 2.25 × the basal width (Fig. 8) and one fourth maximum width of tergum 2, with median longitudinal shallow depression in apical one third (Fig. 8); tergum and sternum separated by distinct furrow. Metasomal tergum 2 with well-developed apical lamella, with preapical depression nearly absent; sternum 2 in lateral view hardly convex ( Fig. 15 ).

Body densely covered with long silvery hairs. Head strongly punctured, covered with long erect hairs in ocular sinus, frons and vertex; hairs in occiput sparser and shorter; clypeus covered with short dense silky hairs; gena covered with long erect hairs. Pronotum and mesoscutum with punctures similar to those on head, covered with dense hairs shorter than those on head; scutellum and metanotum with punctures similar to but sparser than those on mesoscutum; propodeum with puncture similar to preceding parts of mesosoma, with erect hairs longer than those on other body parts. Metasomal segment 1 strongly punctured from base to apex, punctures smaller and sparser than those on mesosoma; tergum 2 densely covered with silky pubescence, punctured as in tergum 1.

Head and mesosoma black, with following bright markings: large interantennal spot, oval spot (specimens from Timor) or narrow band (Komodo) on gena, yellow; narrow band along apical margin of labrum, mandible except black basal part, ventral faces of antennal flagellomeres 9–10, median spot on pronotum, narrow band along outer margin of tegula, propodeal valvula, ferruginous; specimen from Komodo with following additional yellow markings: rectangular basal spot on clypeus, irregularly margined wide band along pronotal carina, minute spot at posterolateral corner of pronotum, dorsal spot on mesepisternum, paired small posterior spots on scutellum, entire part of metanotum. Metasoma black, with following yellow markings: narrow apical band on tergum 1, short narrow apical band on tergum 2 (in one specimen reduced to a spot). Coxae and trochanters black; femora and tibiae dark ferruginous; tarsi dark brown. Wings fusco-hyaline; fore wing slightly darker along outer margin.

Distribution. Indonesia: *Komodo, Timor.
