Synapomorphies for Baeoneurella

Maxillary palp

One palpal sclerite ( Figures 5c View Figure 5 , 7d View Figure 7 , 9d View Figure 9 , 11d View Figure 11 ). A maxillary palp with one palpal sclerite is rare in scelionids, being encountered only in a few genera ( Baeus and some Encyrtoscelio ), and from genera more closely related to Baeoneurella : in Phanuropsis Dodd and in some Trissolcus Ashmead ( Popovici et al. 2017).

Labial palp

Absent. Popovici et al. (2017) found a similar situation only in two scelionid genera – Psix Kozlov and Lê and Paratelenomus Dodd – but a recent study ( Taekul et al. 2014) found that these two genera are somewhat distant from Baeoneurella .

Preoccipital furrow ( Figures 5b,c View Figure 5 , 7d,e View Figure 7 , 9b–d View Figure 9 , 11 b–d View Figure 11 , 13a–c View Figure 13 , 14a,b View Figure 14 )

This structure is not documented in any other scelionid genera. In Baeoneurella it was previously observed by Fabritius and Andriescu (1985) and described as ‘ a ditch on the

median part of vertex ’ (p. 128). In Platygastroidea , a somewhat similar structure is found in Iphitrachelus Haliday ( Figure 3a View Figure 3 ) and Acerotella Masner and named the ‘ occipital pit ’ ( Masner and Huggert 1989). We do not know the value of the occipital pit as a generic character in Iphitrachelus , but in Acerotella there are species with and without this structure ( Figure 3b View Figure 3 ).

Ratio C + R/r-rs

In all Telenominae genera, except Baeoneurella , the vein C + R is shorter than r-rs. Only in Baeoneurella is C + R much longer than r-rs, but this is possibly a consequence of the process of the narrowing of the wings in this genus.

Three-merous clava

Clearly separates Baeoneurella from Telenomus where clava is at least 4-merous.

Characters including the lanceolate fore wings and absence of postmarginal vein have only specific value. There are species with apically rounded fore wings ( B. cumaea , B. blissae , B. cf. nigra ) and at least in B. cf. nigra the postmarginal vein is visibly developed and subequal to the stigmal vein.
