Comments. Arrow (1927) described this species based on specimens from “Tenasserim:Moulmein” and “ Burma: Rangoon ”. The original description by Arrow made no mention of the number of specimens in the type series. Bacchus (1978: 111) reported eleven syntypes in the original series: “ … Syntypes, Burma: 5 ex. (BMNH, London) 3 ex. (IP, Eberswalde), 2 ex. (MCSN, Genoa) Tenasserin, Moulmein, v.1887 (Fea); 1 ex., Burma. [Specimens from Burma: Rangoon, vi and x (Fea) missing.] ”. However, the curators at NHMUK located only one syntype specimen in the collection originating from “Tenasserim: Moulmein”. A further three syntypes were later discovered at SDEI, also from “Tenasserim: Moulmein”. We selected the specimen at NHMUK as the lectotype to keep a single name-bearing individual. The specimen we have chosen as a lectotype carries a lectotype label ( Fig. 44 ) applied by R. Pittino in 1988, but, as far as we know, this lectotype designation was never published and does not constitute a valid lectotype designation. Similarly, the three syntypes discovered at SDEI carry invalid paralectotype labels applied by R. Pittino in 1988. We have designated these three syntypes in that collection as paralectotypes. The designated specimens bear new type labels: “ LECTOTYPE [or PARALECTOTYPE]: | Trox lobicollis Arrow, 1927 | des. Kalawate & Strümpher 2023 ” (printed on red cardstock) ( Fig. 44 ).
