Cicindela andriana Alluaud (1900: 18 , figure 2)

Type material. Syntype female, labeled “ Madagascar (Sud)/Bassin du Mandraré/ Alluaud 1900 48” ( DEIC, examined).

Diagnosis. Length 14.0-17.0 mm. Dorsal coloration as shown in Figures 5, 6 . This species is easily distinguished from the Madagascan C. maheva by its broader yellow markings that run more directly across the width of the elytra (more transverse) than those of C. maheva , particularly on the back (apical) half of the elytra. From the continental African C. regalis , it differs in having the dark elytral markings black when viewed directly from above (these markings are typically metallic blue in C. regalis , but on rare occasions can be black) and in having a much longer yellow marking along the basal portion of the elytral suture. The black elytral markings of C. andriana occasionally will have a metallic blue sheen, especially when viewed obliquely (at an angle).
