Antitrogus mussoni ( Blackburn, 1892)

Rhopaea mussoni Blackburn, 1892: 112 .

Antitrogus mussoni: Britton 1978: 25 .

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

Rhopaea dubitans Blackburn, 1911: 193 ; Britton 1978: 26 (synonymy).

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

Lectotype of Rhopaea mussoni (here designated) male: aedeagus dissected out and mounted on card | Type H.T. (circular red ringed, typeset) | N.S.W. [New South Wales] (handwritten in red) | 4160 (handwritten in red) | Blackburn coll. 1910-236 (typeset) | Rhopaea mussoni, Blackb. T (handwritten) | Syntype (circular light-blue-ringed, typeset) | mussoni (handwritten) | my lectotype label; in NHML.

Paralectotype: Type H. T. (circular red ringed, typeset) | N.S.W. [New South Wales] (handwritten in red) | 4160 (handwritten in red) | Rhopaea mussoni, Blackb. T (handwritten) | Blackburn coll. 1910-236 (typeset) | Syntype (circular light-blue-ringed, typeset) | my paralectotype label; in NHML .

Blackburn (1892) did not define the type series, seeing an unknown number of males and females (vide Articles 73.1.2, 72.1.1) from “near Narrabri” [30.33°S, 149.77°E]. Lea (1912) noted that the ‘type’ had been sent to NHML, and Britton (1978) referred to a “ holotype ” male from near Narrabri in NHML and a female paratype in SAM. Houston & Weir (1992) listed a “ holotype (probable)” in NHML and a “ paralectotype ” in SAM and this was followed by Allsopp (1993a). As Britton (1978), Houston & Weir (1992), and Allsopp (1993a) 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 with its aedeagus dissected out the lectotype. The other syntype in NHML is a paralectotype. I did not find a paralectotype in SAM.

Lectotype of Rhopaea dubitans (here designated) male: aedeagus dissected out and mounted on card | Type H.T. (circular red ringed, typeset) | 5019 N.S.W.
