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 Lepidiota degener Blackburn, 1888 Lepidiota degener Blackburn, 1888b: 853 . Lectotype (here designated) male ( Figs. 17–19 ): N. Territory [ Northern Territory ] (typeset) | LEPIDIOTA de-gener, Blackb. (handwritten by Blackburn) | Type (handwritten in pencil) | I.509 Lepidiota degener Blkb N. Territory (handwritten) TYPE (handwritten in red, at right angle) | SAMA Database No. 25-035293 | my lectotype label; in SAM . Blackburn (1888b) saw two specimens of unknown genders but did not designate a type (vide Article 72.1.1). Britton (1978) referred to a female “ holotype ” and a female “ paratype ”, both from “ Northern Territory ” and in SAM. This was followed by Houston & Weir (1992) . As Britton (1978) and Houston & Weir (1992) provided no discussion and did not label any specimen in SAM as the holotype , neither mention of a holotype constitutes a valid lectotype designation (vide Article 74.5). To stabilise nomenclature, I designate the specimen in SAM labelled as “TYPE” the lectotype . I have not located the second specimen; it must be considered a paralectotype .
