Female. Abdominal chaetotaxy as in Table 3 and Fig. 43View FIGURES 42 – 43. Subgenital plate pentagonal, flaring distally along vulval margin ( Fig. 48View FIGURES 44 – 48). Vulval margin ( Fig. 48View FIGURES 44 – 48) gently rounded, with 3 (rarely 4) short, slender vms on each side, and 2–3 (rarely 4) short, thorn-like vss on each side; 2–3 slender vos on each side anterior to cross-piece and 1 vos median to vss on each side.

Remarks. No significant morphological differences have been found between material from the type host subspecies and the North American subspecies B. g. pallidiceps  . However, North American specimens are generally longer, and females are slightly larger in all dimensions. The population on B. g. pallidiceps  may be a separate species, or natural variation among populations. We have provided the measurements of material from both host subspecies.

Brueelia brachythorax  was not included in the phylogeny of Bush et al. (2016), but Br. cedrorum  was. The two species are very similar and may be conspecific. Brueelia cedrorum  was placed near a few other Brueelia  s. str. from larger-bodied North American hosts, and this clade was placed as sister to a large clade of mainly Holarctic Brueelia  s. str. from emberizid, fringillid, and picid hosts. Brueelia  s. str. occurs mainly on host families that are predominantly Holarctic, or that have representatives that are widely distributed in the Holarctic region, but is largely absent on host families that are exclusively or largely tropical or subtropical.
