Figs 1, 2, 6, 11

Calligaster viridipennis Giordani Soika, 1960: 72, fig. 11 (nos. 7-8), 74, ♂, " Celebes: Enrekang", holotype (ZMB).

Remarks.

Giordani Soika (1960: 72, 74) proposed Calligaster viridipennis for a single male from " Celebes: Enrekang". Since then, no information on this species has been added.

Based on the specimens recently collected in Central and Southeast Sulawesi we describe below the female of this Sulawesi-endemic Calligaster wasp for the first time.

The female can be associated with the male by the combination of the following characters: posterior face of propodeum strongly and reticulately punctured; basal fossa of metasomal sternum II deep and distinct, with dense fulvous hairs; wings fuscous, with strong greenish-purple iridescence.

Female characters.

Body length (head + mesosoma + metasomal segments I and II) 21-22 mm; fore wing length 20 mm. Head in frontal view subcircular, slightly wider than high, 1.2 times as wide as high (Fig. 2). Clypeus in profile smoothly and weakly convex; in frontal view about 1.5 times as wide as high (Fig. 11), with dorsal margin deeply emarginate medially and ventral margin slightly convex.

Mesosoma flattened dorsoventrally, 1.5 times as long as high in lateral view (Fig. 1); in dorsal view 1.4 times as long as wide. Propodeum with posterior face strongly and reticulately punctured (instead of rugosely striated). Metasomal segment I shorter than mesosoma, 0.8 times as long as mesosoma; tergum I strongly convex dorsally (Fig. 1) [moderately convex in Calligaster cyanoptera]; tergum in dorsal view strongly convex along lateral margins, with faint oblique striae (Fig. 6). Metasomal sternum II with basal fossa as in C. cyanoptera, but distinct and deeper, with dense fulvous hairs.

Body densely covered with dense whitish pubescence; tibia and tarsi with golden pubescence. Head strongly punctured, but vertex and gena only sparsely with smaller punctures. Mesosoma strongly punctured; mesoscutum, scutellum and metanotum with punctures sparser and smaller, as those on vertex and gena. Metasomal segment I with punctures slightly stronger than those on C. cyanoptera; tergum I with punctures smaller than those on mesonotum; tergum II with small and superficial punctures, regularly arranged from base to apex.

Body black, without markings. Wings fuscous, with greenish-purple iridescence.
