Diagnosis

Trissolcus basalis can be identified from Nearctic congeners by the combination of the following characters: vertex without hyperoccipal carina, netrion sulcus incomplete, mesopleuron with episternal foveae shallowly impressed, metapleuron without setation and without well-defined paracoxal sulcus; T2 striate ( Figs 1 View Figure 1 , 2 View Figure 2 , 3 View Figure 3 ) ( Talamas et al. 2015).

Distribution

Trissolcus basalis is found worldwide (http://hol.osu.edu/map-large.html?id=3189).

Ecology

At the Tuscaloosa site, T. basalis parasitised four of the 30 sentinel egg masses; at the other two sites, only one of the 30 egg masses was parasitised by T. basalis . Overall, percent parasitism per egg mass was moderately high (62.7%). In general, percent immature mortality was slightly higher for frozen egg masses (48.2%) than for fresh ones (35.4%). Overall, 38.0% of the parasitoids emerged as adults. A female biased sex ratio of 4F:1M was observed for emergent parasitoids.

Biology

Additional host associations of T. basalis , provided by Johnson (1985), are Nezara viridula (L.), Euschistus servus (Say), Euthyrhynchus floridanus (L.), Piezodorus hybneri (Gmelin) and Plautia affinis (Dallas). Additional host associations, provided by Talamas et al. (2015), are Aelia acuminata (L.), Aelia cognata Fieber, Aelia germari Küster, Agonoscelis rutila (Fabricius), Calidea dregeii Germar, Carpocoris fuscispinus (Boheman), Coleotichus blackburniae, Cuspicona simplex Walker, Dolicoris baccharum (L.), Eurydema ornata (L.), Eurygaster austriaca (Schrank), Eurygaster integriceps Puton, Graphosoma semipunctata (Fabricius), Halyomorpha annulicornis (Signoret), Odontotarsus grammicus (L.), Oechalia schellenbergi Guérin-Méneville and Raphigaster Laporte.

Taxon discussion

The CO1 sequences of the two specimens were identical to each other and to the 7 CO1 sequences of T. basalis in Genbank. These sequences derive from specimens collected in Italy, Japan and the United States and their invariance indicates that this gene is not informative for identifying populations within the species.
