Triepeolus rufithorax Graenicher, 1928
Bidens pilosa L., Borrichia frutescens (L.) DC., Lythrum lineare L.
Blacker individuals of this species might be confused with T. lunatus because of the similar shape of the T1 discal patch and the pseudopygidial area; see comments under that species. The T. alachuensis holotype has red integumental coloration restricted apically and laterally on the clypeus, the axillar spines, and anterolaterally on the mesoscutum; orange coloration on the antennae basal to the base of F2, the tegula, the pronotal lobes, and the legs; the T1 discal patch is trapezoidal; and the metasomal banding is narrow. It arguably might have also been synonymized under T. lunatus, but I have placed it here due to the similar type localities of T. alachuensis and T. rufithorax.
