Type host

Pycnonotus finlaysoni Stickland, 1844 – stripe-throated bulbul.

Remarks

Guimaraesiella cucphuongensis was originally illustrated as having a complete cross-piece along the vulval margin. As this character is unusual within Guimaraesiella , we examined one of the paratypes to establish whether or not this illustration is accurate. The distal subgenital plate is poorly sclerotized in this species, and the exact extent of the distal plate is not easy to see. However, on at least one side in the examined paratype, the vulval margin is hyaline laterally, and no complete cross-piece can be seen. Instead, the distal subgenital plate appears to be similar to that of Gu. cinnamomea sp. nov. ( Fig. 7 ).
