Scutellum length: 0.42 – 0.45 mm. Postlumbium half the length of scutellum (length, 0.25 – 0.27 mm). Postnotum: twice as long as scutellum (length, 0.80 – 0.81 mm) (Fig 3 A). Wing: R 1 is infuscated and interrupted in the middle; R 2 arises a little after this and is as long as R 3, R 4 not reaching margin, R 5 is short and arises below R 4, MA, CuA 1, CuA 2 and CuP present and uninterrupted. Length of wing (along its longest length) = 2.77 – 2.83 mm (Fig 3 C). Length of IX th abdominal segment, 0.25 – 0.26 mm (Fig 1 D). Length of adeagus, 0.24 – 0.27 mm (Fig 3 B). Male cephalotheca. Length, 0.86 – 0.88 mm; width, 1.11 – 1.3 mm.

CD1CF8554D1FFF94EE5AF9F212776D1B.taxon	diagnosis	Diagnosis. This is the nineteenth species of Xenos to be described from Mesoamerica and the first from Mexico. The new species is distinguished by short, pointed maxillary palpi which fits in a socket of the basal segment. The aedeagus, with pointed anterior and posterior heads and a hump on the dorsal posterior region, and the lengths of the pro­and mesothorax, are more than a third of the length of the metathorax. The new species can be distinguished from X. zikani which has no basal maxilla segment, a long palpus which is 1 / 8 shorter than mandibles (X. hamiltoni has a long basal segment and very short palpus), R 3 arising close to R 4 and R 5 is absent in the wing (R 3 not arising close to R 4 and R 5 present in X. hamiltoni) and hump on dorsal posterior of aedeagus absent.	en	Kathirithamby, Jeyaraney, Hughes, David P.

CD1CF8554D1FFF94EE5AF9F212776D1B.taxon	etymology	Etymology. The new species is named after the late Bill Hamilton FRS, who inspired us to study the behavioural ecology of the Strepsiptera family Stylopidae.	en	Kathirithamby, Jeyaraney, Hughes, David P.
