Remarks. We have examined material of Traihoriella  from a large number of barbets across South-East Asia, and find these to be Traihoriella binhchauensis  (Najer & Sychra [in Najer et al.], 2014). The phylogenetic reconstruction of Bush et al. (2016) showed that material of Tr. binhchauensis  from three different host species were genetically similar. Bush et al. (2016) also showed that Tr. binhchauensis  was genetically distinct from Tr. punjabensis  , although these species are morphologically very similar. There is considerable morphological variation within Tr. binhchauensis  , e.g. lice from southern hosts generally have smaller heads than material from northern hosts (paralleling the case in Acronirmus gracilis  ). The hosts are all relatively closely related ( Tex & Leonard 2013). The apparent lack of divergence between Tr. binhchauensis  populations on different Psilopgon hosts may suggest ongoing geneflow between lice on different hosts, possibly through shared nest holes or through phoresy.

Contrary to the taxonomic relationships proposed by Najer et al. (2014), Traihoriella binhchauensis  is not closely related to other Vietnamese species of the Brueelia  -complex. Brueelia alophoixi Sychra  [in Sychra et al.], 2009, and Brueelia elbeli Ansari, 1957b  [= Br. acutangulata ( Piaget, 1880)  ], are here retained in Brueelia  s. str., whereas Brueelia glandarii ( Denny, 1842)  is placed in Olivinirmus  .

In addition to the characters given by Najer et al. (2014), Traihoriella binhchauensis  (Najer & Sychra [in Najer et al.], 2014) is most easily separated from Tr. punjabensis  by the lack of aps  on male tergopleurites V –VII in Tr. binhchauensis  , the much smaller head of Tr. binhchauensis  , and differences in the shape of the proximal mesosome. Tr. punjabensis  is most easily separated from Tr. latifrons  by head shape. In most of the material we have examined from Psilopogon lineata hodgsoni  female Tr. punjabensis  do not have any psps on abdominal segment IV, but are otherwise similar; this character may or may not be taxonomically informative.
