Bálint, Zs.: The butterfly taxa described by János Frivaldszky and their type material (Lepidoptera: Papilionoidea)
176 Zs. Bálint "Parnassius Széchenyii" (Papilionidae: Parnassiinae: Parnassiini) (Figs 1,9-10) Parnassius Széchenyii n. sp. - FRIVALDSZKY 1886: 39, pl. IV, fig. 1 (male dorsum), la (male ventrum); syntype male(s): "In Tibet ad lacum Kuku-noor". Parnassius Széchenyii Friv. - FRIVALDSZKY 1893: 687. Parnassiusszechenyi Friv. - STICHEL in SEITZ 1909: 31, pl. 15, rowe, fig. "szechenyi". Parnassius szechenyii Frivaldsky, 1886 - D'ABRERA 1990: 23, "Tibet, Western China", figs "P. szechenyii". Parnassius (Koramius ) szechenyii ssp. szechenyii FRIVALDSZKY, 1886 - WEISS 1992: 50, figs 1-2. Type material - Syntype male, set dorsally, right antenna missing (Fig. 9), labelled as (1) "51" (green quadrant label); (2) "2." (yellowed oblong label); (3) "Type." (János Frivaldszky's handwriting); (4) "Monotypus 1886. // Kuku-nor, Amdo // Koramius // Széchényii // J. Frivalszky" on verso: " Természet. II Füzetek II V.lO.p. 39. II 1886" [handwriting of an unknown person] (Fig. 10). History - This taxon was described on the basis of an unstated number of male syntype specimen(s) taken at the lake Kuku-noor (now: Quignhai Lake, Quinghai, China). Although there is no indication in the original description it can be excluded with certainty that there was no female syntype specimen. The sphragis of Parnassius szechenyii is conspicuous, and the female abdomen covered by different type of hairs (see D'ABRERA, I.E.). These cannot be overlooked. A single male specimen was located in the general collection. The specimen located perfectly matches "Fig. 1." of the original plate which depicts a full set butterfly individual in dorsal view (Fig. 1 ). This specimen is considered as syntypic, and designated as lecotype for objectively fixing the identity of the nominate subspecies of Parnassius szechenyii. The species is geographically variable, and the taxonomic status of certain subspecies is questionable. At present P. szechenyii is considered to be a widely distributed polytypic species represented by 17 (!) subspecies (WEISS 1992). Remarks - The label no. 4 of the lectotype is a standard type label used in the HNHM after the 2 n d World War and generally filled by hand. Similar labels with identical handwriting can be found in Parnassius specimens originating from the famous Apollo Butterfly collection of ABA KERTÉSZ (1857-1924) (ANONYMUS 1924). According to SZENT-IVÁNY (1938: 69), the collection was not yet amalgamated before the 2 n d World War with the general collection. Accordingly that part of the general collection which contains Parnassius specimens including the KERTÉSZ material was built after 1945, and all the types were labelled by the same person, who was able to find only a single P. szechenyii type specimen and labelled accordingly as "monotypus". The identity of the person was not found out. This worker, Annls hist.-nat. Mus. natn. hung. 101, 2009
