Genus Masona van Achterberg, 1995
Masona van Achterberg, 1995: 97 .
Type species Masona prognatha van Achterberg, 1995, by original designation.
Masonia [sic] – van Achterberg 1995: 154–155. Incorrect subsequent spelling of Masona van Achterberg, 1995 .
Diagnosis
The genus Masona has a highly unusual morphology relative to the rest of Ichneumonoidea . Quicke et al. (2019b) slightly modified the diagnosis of the genus (and therefore of the subfamily) based on the description of [ Masona] timpaynei Quicke, 2019 . However, the latter is hereby treated as incertae sedis in the subfamily Neorhacodinae (see below), and, therefore, we report the original characters used to diagnose the genus: (1) head prognathous in most of females, orthognathous in males; (2) ocelli absent in the female, present in the male; (3) occipital carina absent ventrally; (4) labial palps one-segmented; (5) female wingless, males macropterous; (6) all femora strongly swollen in females; (7) ovipositor short, upcurved, with a long shallow dorsal notch.
Remarks
In the captions for the species Masona prognatha, van Achterberg (1995: 154–155, figs 12–32) wrote the genus name as Masonia, which also appears on the original holotype label of the species (van Achterberg (1995: fig. 9A). This is clearly a misspelling that unfortunately has never been reported before. Masonia should be considered an incorrect subsequent original spelling of the genus Masona, rendering the name unavailable (ICZN 1999: Article 33.3).
