Character

Position of propodeal spiracle [129]

Description

The longest axis of the spiracle was used to measure its diameter. State 1 was originally a character used to differentiate Ceinae (Pteromalidae), but it is also found in some other taxa. In some instances length of the propodeum relative to size of the spiracle complicates interpretation of this character. For example, only state 0 is possible in Signiphoridae because the total length of propodeum is only about 3X the diameter of spiracle, although the spiracle is in the middle of propodeum. This is the same for most Neanastatinae and female Phenaceupelmus (Eupelminae), in which the propodeum is more or less transverse and the spiracle is at about midlength. Because of the length of the propodeum and the size of the spiracle, only state 0 is possible for these taxa (Gibson, 2009). However, male Phenaceupelmus have state 0 because the propodeum is longer and the spiracle is obviously closer to the anterior than posterior margin.
