Discussion. Smith (1853) described this species from the Cape of Good Hope, which could be almost any part of South Africa. A female syntype has been studied. Smith (1879) described consanguinea, from KwaZulu-Natal, which was later synonymized with ianthoptera by Cockerell (1937). The type material has been studied and they are conspecific. Further, zamelaena was described as a variety of consanguinea by Cockerell (1937), and is here synonymized with ianthoptera, following the examination of the type.
Diagnosis. Female. Vestiture on face, gena, mesosomal pleuron and venter, basal segments of legs, propodeum and lateral region of metasomal dorsum white, vertex and scutum with black and white hairs intermixed, tibiae and tarsi black, mediolongitudinal region of metasoma black (Fig. 4a–b); scopa black laterally, orange medially (South Africa) or completely black (Zimbabwe). Lengths: face 3.2–4.0 mm, scutum 2.5–3.0 mm, forewing 10.1–12.8 mm, body 11.5–14.5 mm. Structure. Clypeus more than twice as wide as long, strongly convex, densely punctuate, ventral edge straight (Fig. 4a); clypeocellus: clypeus 1:0.6; scopal hairs blunt, thickened distally.
Male. Vestiture mostly white, face sometimes pale yellow (Fig. 4c), vertex and scutum with black and white hairs intermixed, tarsi mostly orange, T2–T5 with centre of discs black (white laterally) (Fig. 4c–e). Lengths: face 3.5–3.6 mm, scutum 2.2–2.7 mm, forewing 10.2–11.0 mm, body 12.8–13.8 mm. Structure: Clypeus convex above, flat below, ventral edge straight; mandible with four teeth, middle two small, ventral edge with small tooth; foretarsus unmodified; T6 shield–like, with mediolongitudinal carina, distinctly concave posteromedially, toothed distal edge, truncate posteriorly (Fig. 4e); S4-S5 unmodified; S6, S8 and gonocoxite as in M. cognata (cf. Fig. 2d–f).
Distribution (Fig. 5). Megachile ianthoptera occurs mainly through the southern and eastern parts of southern Africa, and its distribution extends further north beyond southern Africa.
Biology. Flowers of Acacia cf. mellifera, Aspalathus spicata, Asteraceae, Centaurea sp., Crotalaria sp., Cyperaceae, Delonix regia, Helianthus cf. fagonia, Justicia sp., Leucaena sp., Mimosa pigra, Ocimum sp., Psophocarpus sp., Psoralea pinnata, Tephrosia sp., Vicia sp. and Vigna sp. are visited by M. ianthoptera.
