In the key to South African Dasiops species (McAlpine
1960) the only species with a combination of white fringed calypteres, partly yellow
tarsomeres and lunule lacking pock-like depressions are D. rugicavus McAlpine,
1960 and D. concavifrons McAlpine, 1960. Both of these species have hairy or
pubescent eyes and their aculeus, although broad, does not have an apical segment
with straight sides and an acute apex and both are easily distinguished from D.
