Type material.

Holotype: Chile • ♀ ( MNNC); Osorno , Parque Nacional Puyehue, Antillanca; 40 ° 46 ' 55 " S, 72 ° 12 ' 39 " W; alt. 987 m; 9–23 Dec. 2019; D. Amorim and V. Silva leg.; Malaise trap . Paratypes: Chile • 1 ♀ ( MNNC) and 1 ♂ ( MNNC); same data as for holotype • 2 ♀♀ ( DCBU 509931 , DCBU 514733 ) and 1 ♂ ( DCBU 509539 ); same data as for holotype .

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, at least slightly (Fig. 84 ); mandible with three relatively large teeth, diagonal carina present, mandibular apex wider than base (Fig. 88 ); F 1 2.4–2.8 × as long as wide (Fig. 85 ); mesoscutal pit present, conspicuous, prescutellar depression with lateral carinae (Figs 89 , 91 ); propodeum with areola, median longitudinal carina incomplete to complete, transverse carinae complete (Fig. 92 ); fore wing vein cu-a postfurcal, 1 - CU 1 shorter than cu-a (Fig. 83 ); hind tibia 9.4–9.6 × as long as wide (Fig. 93 ); metasoma distinctly wider than mesosoma (Figs 89 , 94 ).

Dinotrema (S.) puyehue sp. nov. is similar to D. (S.) daltoni sp. nov., D. (S.) flavum sp. nov. (their differences are given in the identification key), and D. (S.) perisfelipoi sp. nov. (see their differences in the diagnosis of the latter).
