Diagnosis

Male. Body length 1.9-2.5 mm. Face without malar sulcus, pleurostomal distance slightly wider than shortest distance between eyes. Malar distance 0.45-0.55 times as long as largest diameter of eye. Front smooth. Аntennae dark brown, slender and long, with A5-A12 2.3-3.3 times as long as wide. A4 1.2-1.25 times as long as A3 and with keel and emargination reaching to 0.5-0.55 of the segment length (Fig. 11 D). Notauli almost complete, but shallow anteriorly (Fig. 11 B). Scutellum convex, 1-1.2 times as long as wide (measured without anterior scutellar pits). Propodeum with not deep emargination between plicae in dorsal view. Basal vein and distal part of CU dark and sclerotised. Marginal vein short, less than 1.5 times as long as wide. Petiole elongate, 1.7-1.8 times as long as wide. T2 pubescent at the base. S8 almost smooth, with few setae and very weak elongated wrinkles.

Distribution

Algeria, Austria, Czech Republic, France, Germany*, Hungary, Italy*, Portugal, Russia (European part).

Notes

The most important features of this species, such as malar and pleurostomal distances cannot be examined in the lectotype of Tritopria lusitanica because the face of the type specimen is hidden in glue. However, secondary diagnostic characters (proportions of the remaining antennomeres, width of the head and proportions of the scutellum) lead us to believe that all type specimens belong to a single species and correspond with the examined material mentioned above under the name Spilomicrus lusitanicus . The females are unknown. The females described by Chemyreva (2021) belong to the S. brevimalaris sp. nov.
