Diagnosis

This new species is similar to Synaldis novateutoniae sp. nov. and S. segmentata Fischer, 1967. Synaldis longiflagellaris sp. nov. differs from Synaldis novateutoniae sp. nov. in having the first flagellar segment 4.0 times as long as its maximum width (3.5 times in S. novateutoniae sp. nov.), second segment 3.2– 3.3 times (2.3 times in S. novateutoniae sp. nov.) and middle segments 2.5–2.9 times (1.8–2.0 times in S. novateutoniae sp. nov.) as long as their maximum width, face 1.6 times as long as high (1.8 times in S. novateutoniae sp. nov.), and vein SR1 3.0 times as long as vein 3-SR (2.6 times in S. novateutoniae sp. nov.). Synaldis longiflagellaris sp. nov. differs from S. segmentata in having the first flagellar segment 4.0 times as long as its maximum width (3.0 times in S. segmentata), second segment 3.2–3.3 times (2.0 times in S. segmentata) and middle segments 2.5–2.9 times (1.5 times in S. segmentata) as long as their maximum width, mandible 1.6 times as long as wide (1.3 times in S. segmentata), marginal cell 4.0 times as long as its maximum width (3.5 times in S. segmentata), and vein SR1 3.0 times as long as vein 3-SR (1.8 times in S. segmentata).

Etymology

The name is referring to the long size of the flagellar segments of antennae.

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 long transverse carinae not reaching sides of propodeum. Propodeal spiracles small, its diameter about 0.1 times as large as distance from spiracle to anterior margin of propodeum.
