Rhopaea assimilis Blackburn, 1911 Rhopaea assimilis Blackburn, 1911: 191. Rhodaea assimilis: Lea 1912: xxxvi (in error). Lectotype (here designated) male: Type H. T. (circular red ringed, typeset) | 3270 Bulli [34.30°S, 150.92°E] (red, handwritten) T (handwritten) | Blackburn coll. 1910-236 (typeset) | RHOPAEA assimilis Blackb. (handwritten) | aedeagus dissected out and mounted on card | my lectotype label; in NHML. Blackburn (1911) did not define the type series, seeing an unknown number of males (vide Articles 73.1.2, 72.1.1). Lea (1912) noted that the ‘type’ had been sent to NHML, and Britton (1978) referred to a “ holotype ” male from Bulli in NHML. Houston & Weir (1992) listed a “ holotype (probable)”. As Britton (1978) and Houston & Weir (1992) provided no discussion and did not label any specimen in NHML, neither mention of a holotype constitutes a valid lectotype designation (vide Article 74.5). To stabilise nomenclature, I designate the male in NHML the lectotype.
