Clarification of the status of the types of Australian Melolonthini (Coleoptera Scarabaeidae: Melolonthinae) described before 1950 Author Allsopp, Peter G. text Zootaxa 2020 2020-11-27 4885 4 451 486 journal article 9372 10.11646/zootaxa.4885.4.1 00507d5f-328a-4506-8b7f-132a7df3786d 1175-5326 4296848 2E69687C-74B4-4087-9BF6-039F5FE14A9E Rhopaea laticollis Blackburn, 1911 Rhopaea laticollis Blackburn, 1911: 192 . Rhodaea laticollis : Lea 1912 : xxxvi (in error). Lectotype (here designated) male: Type H. T . (circular red ringed, typeset) | 2095 Inverell [ 29.78°S , 151.12°E ] (handwritten in red) T (handwritten) | Blackburn coll. 1910-236 (typeset) | RHOPAEA laticollis, 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) from Inverell. Lea (1912) noted that the ‘type’ had been sent to NHML, and Britton (1978) referred to a “ holotype ” male from Inverell in NHML. Houston & Weir (1992) listed a “ holotype (probable)” from the same locality. As Britton (1978) provided no discussion and did not label any specimen in NHML, and that Houston & Weir (1992) were unsure of the status of the type, neither mention of a holotype constitutes a valid lectotype designation (Article 74.5). To stabilise nomenclature, I designate the male in NHML the lectotype .
