Diagnosis.

This species differs from other New World species of Synaldis by the combination of the following characteristics: in lateral view, eye shorter than temple (Fig. 66 ); mandible with three relatively large teeth, diagonal carina present in ♀ (absent in ♂), mandibular apex wider than base; F 1 2.4–2.8 × as long as wide (Fig. 67 ); mesoscutal pit present, conspicuous; propodeum with areola, median longitudinal carina incomplete to almost complete, transverse carinae complete (Fig. 70 ); fore wing vein (r + 3 - SR) 6.2–6.3 × as long as r-m, cu-a postfurcal, 1 - CU 1 shorter than cu-a (Fig. 69 ); hind femur 4.6 × as long as wide, hind tibia 8.9–9.2 × as long as wide (Fig. 71 ).

Dinotrema (S.) perisfelipoi sp. nov. is similar to D. (S.) daltoni sp. nov. (see their distinctions in the diagnosis of the latter) and D. (S.) puyehue sp. nov., from which it differs by prescutellar depression smooth laterally (with complete lateral carinae in D. (S.) puyehue sp. nov., Fig. 91 ), fore wing vein (r + 3 - SR) 6.2–6.3 × as long as r-m (5.0–5.2 × in D. (S.) puyehue sp. nov.), submarginal cell 2.7–2.9 × as long as wide (2.05–2.20 × in D. (S.) puyehue sp. nov., Figs 69 , 90 ), AF 2.5–2.6 × as long as wide (1.9–2.2 × in D. (S.) puyehue sp. nov., Figs 67 , 86 ).

Etymology.

The species name perisfelipoi is a genitive noun, named in honor of Francisco Javier Peris Felipo, an expert in Alysiinae wasps, who has made significant contributions, particularly in his study of the genus Dinotrema.
