Diagnosis

This new species is similar to Synaldis fritzi sp. nov.; differences between both species are described under the latter species.

Etymology

The specific epithet is derived from the Latin “magnus”, meaning “big”, and “oculus”, meaning “eye” because of the large eye in lateral view.

Material examined

Holotype BRAZIL: ♀, Nova Teutonia, 27º11′ S, 52º23′ E, 30 Apr. 1938, F. Plaumann leg. ( BMNH: B.M. 1938– 682 ).

Paratypes BRAZIL: 1 ♀, same data as holotype ( BMNH).

Description

Female (holotype)

LENGTH. Body 1.7 mm, fore wing 1.8 mm, hind wing 1.4 mm.

COLOUR. Body, pterostigma and flagellar segments of antenna brown, scape and pedicel of antenna brownish yellow. Lower part of pronotal side and propleuron yellow. Legs yellow. First metasomal tergite similar colour to second and third tergites. Wings hyaline.

HEAD. In dorsal view, 1.7 times as wide as long, 1.4 times as wide as mesoscutum, smooth, with temple rounded behind eyes. Eye in lateral view 1.5 times as high as wide and 1.7 times as wide as temple medially. POL 0.9 times as long as OD; OOL 2.4 times OD. Face 1.2 times as wide as high, with numerous setae; inner margins of eyes subparallel. Clypeus 2.5 times as wide as high, slightly concave ventrally. Paraclypeal fovea reaching half distance between clypeus and eye. Mandible not widened towards apex, 1.9 times as long as its maximum width. Upper tooth very small, shorter than middle tooth; middle tooth small, wide basally and pointed apically; lower tooth short, as long as upper tooth, rounded. Antennae 20-segmented, 1.1 times as long as body. Scape 2.0 times as long as pedicel. First flagellar segment 3.5 times as long as its apical width, 1.4 times as long as 2nd segment. Second flagellar segment 2.5 times, 3rd to 5th segments 2.1 times, 6th to 8th segments 2.5 times, 9th to 17th segments 2.2 times, and 18th (apical) segment 2.4 times as long as their maximum width.

MESOSOMA. In lateral view 1.2 times as long as high. Mesoscutum (dorsal view) as long as its maximum width, with sparse single setae arranged along notaulus line. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present and elongate. Prescutellar depression smooth, without lateral carinae. Precoxal sulcus present, crenulate, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum sculptured, with complete and distinct median longitudinal carina from its base to apex, with one transverse carina reaching both sides of propodeum. Propodeal spiracles relatively small, its diameter 0.2 times as wide as the distance from spiracle to anterior margin of propodeum.

WINGS. Length of fore wing 2.7 times its maximum width. Marginal cell ending on apex of wing, 3.8 times as long as its maximum width. Vein SR1 2.6 times as long as vein 3-SR. Vein 3-SR 1.8 times as long as vein r. Vein cu-a distinctly postfurcal. First subdiscal cell closed distally, 4.0 times as long as its maximum width. Hind wing 5.7 times as long as its maximum width.

LEGS. Hind femur 3.9 times as long as its maximum width. Hind tibia weakly widened to apex, 9.6 times as long as its maximum subapical width, as long as hind tarsus. First segment of hind tarsus 1.7 times as long as second segment.

METASOMA. First tergite weakly widened towards apex, 2.7 times as long as its apical width, striate. Ovipositor 1.2 times as long as first tergite, 0.4 times as long as metasoma, 0.8 times as long as hind femur.

VARIATION. Hind femur 3.8–4.0 times as long as its maximum width.

Male

Unknown.
