DISTRIBUTION. — Philippines and Indonesia (Sulawesi, Sula Islands: Mangole) (Fig. 16). REMARKS Amegilla samarensis was described from a single female from the island of Samar, and the holotype specimen (NHMUK) is actually labelled as “ Anthophora zonata samarensis ” (Fig. 19), but it was published as Anthophora whiteheadi ssp. samarensis (Cockerell & LeVeque 1925: 170). Examination of the RMNH collection has revealed many specimens determined by Lieftinck from the Philippines and Sulawesi. This included the undescribed male of Amegilla samarensis (Fig. 20) which can be immediately separated from Anthophora whiteheadi due to the apical margin of S5 which is essentially straight,with only very weak scalloping (Fig. 20D), with the surface of S6 also lacking a semi-circular depression and longitudinal keel (Fig. 20D). Females are slightly more challenging to recognise, but can be separated as in Amegilla whiteheadi the tibial scopa is almost entirely composed of yellowish hairs with a line of black hairs along the ventral margin of the hind tibiae, whereas in Amegilla samarensis the tibial scopae is composed of predominantly dark brown hairs with a broad line of dusky yellowish hairs along the dorsal margin of the hind tibiae.Whilst this is a colour difference, it has been able to examine a large number of Amegilla whiteheadi female specimens from Sulawesi and elsewhere,and the character appears stable. Moreover, the colouration of the tergal hairbands is bright light sky blue in Amegilla whiteheadi and dark turquoise blue in Amegilla samarensis. The hairbands are also comparatively broad in Amegilla whiteheadi, occupying around 25% of T2, 40% of T3 and more than 50% of T4, whereas in Amegilla samarensis they occupy <20% of T2 and around 25% of T3 and T4. With these differences combined, separation can be made with confidence.
