Differences with X. hebraei View in CoL and X. vesparum
X. gadagkari is phylogenetically closest to X. vesparum (according to currently available sequences). However, X gadagkari is morphologically different from X. vesparum particularly due to the drastic difference in colouration. In the female cephalotheca, the mandibles of X. gadagkari are positioned in a depression larger than their length, while in X. vesparum the depression around the mandibles is smaller than the length of the mandibles. Also, the lower margin below the semicircular field possible of labral region (SES) is elevated ( Fig 15c View FIGURE 15 ) in X. gadagkari , while it is smooth in X. vesparum ( Fig 2D View FIGURE 2 in Richter et al. 2017).
As the description of the adult male X. hebraei is unavailable, it is not possible to compare them. However, according to the description of the female cephalothorax of X. hebraei ( Kinzelbach 1978) ‘the clypeo-labral region protrudes less than in any other of the species of western Palearctic’. The protrusion of the clypeo-labral region in X. gadagkari is more pronounced than X. vesparum ( Fig 15d View FIGURE 15 of this study compared with Fig 2D View FIGURE 2 of the study on X. vesparum ( Richter et al., 2017) . Kinzelbach (1978) further described that ‘the posterior delimitation of the brood aperture is shifted far forward’ while the lateral margins of the brood aperture reach the anterior margin of the head. In X. gadagkari , neither of these two characters is different from X. vesparum i.e. the posterior delimitation of the brood aperture is not shifted forwards and the lateral margins of the brood aperture end way before reaching the anterior margin of the head. Although body size may vary between hosts, a morphometric and colour comparison of X. gadagkari with the available data from X. vesparum and X hebraei is compiled in table 2.
