Antitrogus consanguineus ( Blackburn, 1911)

Rhopaea consanguinea Blackburn, 1911: 194 .

Antitrogus consanguineus: Britton 1978: 25 .

Rhodaea consanguinea: Lea 1912 : xxxvi (in error).

Lectotype (here designated) male: Type H. T. (circular red ringed, typeset) | aedeagus dissected out and mounted on card | 4630 N.Q. [North Queensland] (handwritten in red) T (handwritten) | Blackburn coll. 1910-236 (typeset) | RHOPAEA consanguinea, Blackb. (handwritten) | 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 North Queensland in NHML. Houston & Weir (1992) listed a “ holotype (probable)” and Allsopp (1993a) and Miller & Allsopp (2000) followed this interpretation. As Britton (1978), Houston & Weir (1992), Allsopp (1993a), and Miller & Allsopp (2000) provided no discussion and did not label any specimen in NHML, none of these mentions of a holotype constitutes a valid lectotype designation (vide Article 74.5). To stabilise nomenclature, I designate the male in NHML the lectotype.

This species was synonymised under Antitrogus mussoni ( Blackburn, 1892) by Britton (1978) but reinstated by Allsopp (1993a: 196).
