Dark green mesopleuron and metasoma with coppery reflections. Reticulated sculpturing, reticulate-rugulose on the mesoscutum, scutellum and head.</p><p>A key to 60 of the 122 Australian  Psyllaephagus fauna was published by Riek (1962). When assessing the female holotype of  P. migrator against this key, the key terminates at couplet 43 (44)  P. discretus .  Psyllaephagus migrator differs from  P. discretus in head, club and coxal color. Specifically, in the description for  P. discretus the head color is described as green, antennal club slightly darkened, mesocoxa slightly darkened at base and metacoxal dark.  Psyllaephagus migrator has a purple head with blue reflections, light brownantennal club, and all coxae are yellow ..</p><p>The Australian species that are not included in Riek’s key have been morphologically examined and were eliminated. Specifically, the three species described by Walker (1839) all have a significant space between the posterior ocelli and the eye margin, whereas  Psyllaephagus migrator has a marginal space. The key morphological differences separating the new species from the other described Australian species,  P. iridus, are leg color (yellow in  P. migrator versus dark brown / bi-colour in  P. iridus) and peg pattern on the basitarsus (two sharply angled opposing rows of pegs in  P. migrator versus one continuous row of pegs in  P. iridus). Males of  P. iridus also have very distinct yellow-ended, capitate antennae. As in McClelland et al. (2023),  Psyllaephagus migrator is not diagnosed against the Australian species described by Girault due to the morphologically uninformative state of his type specimens.</p><p>Psyllaephagus migrator was diagnosed against the valid North American species (Suppl. material 3) and superficially resembles  P. pachypsyllae, known only from North America (Noyes, 2023).  P. migrator differs from  P. pachypsyllae in the characteristics of the tegula. The tegula base in  P. migrator is dark brown in females, light brown in males. The tegula in  P. pachypsyllae is pale yellow at the base.</p><p>Description.</p><p>Females can be identified by the following combination of characters: prepectus dark brown anteriorly with white posterior edge; tegula light brown, sometimes with darker brown patches; legs pale yellow, apical segments with dark brown tips; mesotarsus with distinct row of orange pegs on underside; mesotibial spur stout; base of metatibia fringed with stout orange hairs; ovipositor slightly extruded; three very long cercal hairs; dark brown scape; space between posterior ocelli and eye margin less than a quarter diameter of ocelli; distance between posterior ocelli slightly greater than distance between posterior and anterior ocelli; pedicel and first two funicle segments dark brown, remaining segments light brown flagellum clavate with fine, pale setae and slight but discernible space between funicle segments.</p><p>Males smaller than females, with green reflections (where females are blue) and with reticulate sculpturing as in females. Additionally, the following characters can be used to identify males of  Psyllaephagus migrator: Prepectus dark brown anteriorly with white posterior edge, tegula light brown, sometimes with darker brown patches; legs pale yellow, tarsomeres light brown; tarsal characters as for females; space between posterior ocelli and eye margin approximately one third diameter of ocelli; distance between posterior ocelli almost twice distance between posterior and anterior ocelli; scape yellow pedicel dark brown; antenna serrate, light brown, with short pale setae; small but distinct space between funicle segments.</p><p>All measurements are in millimeters.</p><p>Female.

However, the species is likely to be more broadly distributed given that its host psyllid,  Boreioglycaspis melaleucae, has spread to all 22 central and southern Florida counties, and has been collected and recorded from all Australian states and territories except South Australia (Burkhardt 1991). The psyllid’s host plant,  Melaleuca quinquenervia is a widespread invasive plant in Florida and is recorded from coastal regions of all Australian states and territories.</p><p>Etymology.</p><p>The species epithet,  migrator, meaning wanderer or immigrant in Latin and references the vast distance between the locations where the species has been collected.</p><p>Comments.</p><p>The malar space on the male allotype is partially obscured and so the measurement given is taken from three other males in the type series. In females, it is difficult to accurately measure the ovipositor without dissecting and slide mounting the specimen and so the decision is made to measure the extrusion of both sheath and stylets past the terminal end of the outer ovipositor plate, in lateral view. In both sexes, the pronotum is difficult to measure as it curves markedly and is very small. The length is taken at the midpoint of the pronotum, dorsally, with the body not tilted.</p><p>Although not exclusively suitable for morphological diagnosis, we also present images of the immature stages of  P. migrator (Fig. 8) completing a set of high-resolution biological and diagnostic images from host to adult.</p></div>	https://treatment.plazi.org/id/8558450890585A6D8132429D1D91A960	Public Domain	No known copyright restrictions apply.
