Blepharida macarthuri Bryant, 1948: 150

Blepharidina macarthuri (Bryant): Biondi et al. 2017: 131

Type material examined. Lectotype ♂ (Biondi des. in Biondi et al. 2017): “(KENYA) MacArthur and Museum Staff., Ikutha (2°04′12''S, 38°10′48''E). 1–42” (BMNH) . Paralectotypes: KENYA, “Makindu (2°16′30''S, 37°49′12''E), xii.1933, MacArthur”, 1 ♀ (BMNH). Additional material examined in Appendix 1 .

Taxonomic observations. Blepharidina macarthuri shows clear affinities with B. ornaticollis . These two species share: similar size, habitus, sculpture of the dorsal integuments (Figs 13, 15), anterior margin of the pronotum slightly thicker medially than laterally (Figs 23, 25); anterior angles of the pronotum sharply pointed and laterally oriented (Fig. 31), and dorsal surface of the aedeagus densely carinate longitudinally (Figs 49, 51). However, B. macarthuri is mainly distinguishable by the more slender distal part of the aedeagus (Figs 49, 51), and the spermatheca with thicker and subcylindrical basal part (piriform and elongate in B. ornaticollis) (Figs 60, 62). Morphometry in Appendix 2.

Distribution. Kenya (Fig. 69). Possibly Northern–Eastern Afrotropical (NEA) chorotype.
