Macroglenes zdeneki sp. nov.

(Fig. 31)

Etymology. The species is named for Dr. Zdenek Bouček, for his great contributions to the knowledge of world Chalcidoidea.

Diagnosis. Body black, without metallic reflections; clypeus medially incised (cf. Fig. 32); funicle with all segments anelliform, similar to M. incisiclypeatus sp. nov., but F1–F3 pale to bright yellow (cf. Fig. 8); mesosoma completely flattened (cf. Fig. 11); pecten regular, slightly more than half length of hind tibia (cf. Fig. 14, but less extended); basal cell with 5 hairs near basal vein, bare area between R and apical margin of wing present; ovipositor sheaths about 1/3–1/4 as long as hind tibia; hypopygium reaching about 4/5 length of gaster (Fig. 31).

Description. Female.

Body length. 1–1.2 mm.

Color. Body black, without metallic reflections. Coxae black, femora and tibiae brown, extremities of tibiae slightly paler. Tarsi yellowish, distal segment brown. Scape, pedicel, F4–F5 and clava brown, F1–F3 yellowish to bright yellow. Mandible light brown. Eye dark red. Tegula and venation brown, wings hyaline.

Head. In frontal view about as high as wide. Clypeus medially incised, incision slightly shallower than in M. incisiclypeatus sp. nov. Eye height about 1.5–1.7X length. Malar space about 0.3–0.4X as long as eye height. Scape shorter than eye height, about 4–5.2X as long as broad; combined length of pedicel and flagellum distinctly less than breadth of head; pedicel length in lateral view 1.6–1.9X width; funicular segments similar in shape with those of M. incicyclypeatus sp. nov. except F5 more transverse, width about 2.8– 3 X length; clava length 2–2.3X width, distinctly longer than combined length of pedicel plus F1–F5.

Mesosoma. Flattened, scutellum and propodeum virtually in same plane. Mesosoma length about 1.3– 1.4X width. Forewing length about 2.2–2.4X width, rather sparsely pilose; speculum extending to R; venation: M about 5–5.6X as long as R, P slightly shorter than R; stigma similar in shape to that of M. incicyclypeatus sp. nov.; basal cell with 5 hairs near basal vein; with bare area between R and apical margin of wing. Pecten regular, slightly more than half length of hind tibia.

Gaster (Fig. 31). Including ovipositor sheaths, about 1–1.1X as long as mesosoma, length about 1.6–1.9X width (length up to 3.4X width in one specimen with strongly laterally compressed gaster). Ovipositor sheaths about 1/3–1/4 as long as hind tibia. Hypopygium reaching about 4/5 length of gaster.

Male. Unknown; based on the flattened mesosoma of female, the male is expected to have normally developed eyes and an inflated antennal scape, as in M. chalybeus or M. varicornis .

Comments. This species may be the same as M. incisyclypeatus sp. nov. which is very similar. However, I consider the morphological differences, even if small, and the difference in geographical distribution enough to regard both as valid species.

Distribution. Czech Republic, Romania, Switzerland.

Hosts. Unknown.
