Proterosceliopsidae are parasitoid wasps that lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these. This is a female.
Taxonomy according to Fossilworks.org.
Diagnosis for the family Proterosceliopsidae according to Talamas et al. 2019, p. 20: “Antenna with 14 or 15 antennomeres; malar sulcus present (Fig. 7); facial striae absent (Fig. 7); malar striae absent (Fig. 7); pronotal cervical sulcus present as a furrow of fine setation associated with glandular excretion (Figs 16, 48–49, 51–53, 59); mesopleuron with transepisternal line and mesepimeral sulcus (Figs 16, 51–53, 59, 63); T3–T5 and S3–S5 anteriorly with depressions associated with glandular excretion (Figs 29, 34, 56, 58, 62).”
Several very similar looking species have been described from amber deposits in Myanmar: P. ambulata, P. plurima, P. torquata, P. masneri, P. nigon and P. wingerathi. A more exact assignment is not possible for me.
Identified by oilshale as Proterosceliopsis sp. using Talamas et al. 2019.
