Diagnosis

This new species is similar to Synaldis longiflagellaris sp. nov. and S. segmentata Fischer, 1967 . Differences between S. novateutoniae sp. nov. and S.longiflagellaris sp. nov. are described after the description of S.longiflagellaris sp. nov. Synaldis novateutoniae sp. nov. differs from S. segmentata in having the first flagellar segment 3.5 times as long as its maximum width (3.0 times in S. segmentata ), second segment 2.3 times (2.0 times in S. segmentata ) and middle segments 1.8–2.0 times (1.5 times in S. segmentata ) as long as their maximum width; mandible 1.8 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 2.6 times as long as vein 3-SR (1.8 times in S. segmentata ).

Etymology

The specific epithet refers to Teutônia (“Nova Teutonia”), the type locality of the species.

Precoxal sulcus present, 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 very short transverse carinae far from reaching sides of propodeum.
