Diploxys (Paracoponia) holubi Horváth, 1893

( Figs 53–55 )

Diploxys (Paracoponia) holubi Horváth, 1893: 257 (original description). Diploxys (Paracoponia) Holubi : LETHIERRY & SEVERIN (1893): 268 (catalogue).

Diploxys (Paracoponia) holubi : KIRKALDY (1909b): 74 (catalogue); LINNAVUORI (1975): 37 –38 (differential diagnosis, inadvertant lectotype designation, line drawings of pronotum, last paratergite, apex of profemur, genital capsule and paramere, type material).

Diploxys Holubi : SCHOUTEDEN (1909): 51 (listed).

Coponia holubi: LINNAVUORI (1982a): 80 (new combination, diagnostic character).

Type locality. ‘Africa centralis (HOLUB).’ [= Southern and southern-central Africa between Cape Town and Kafue River, Zambia].

Type material examined. LECTOTYPE (designated by LINNAVUORI 1975:37, as type):, ‘Holub [p] // Paracoponia / Holubi Horv.[Horváth’s hw]’ ( Figs 53–55 ) (pinned through right corium, distiflagellum of right, flagellum of left antenna, left fore tarsus, apex of right middle tarsus, tibiae and tarsi of left middle and both hind legs lacking, genital capsule removed, macerated, dissected, its parts glued to card, pinned with the specimen). Topotypic material examined. 1 ♀ ( NMPC), ‘Holub [p, pink label] // 9. [hw, green label] // ♀ [p] // Diploxys / Holubi / Horv.n. sp. [hw]’ (pinned through scutellum); 1 ♀ ( NMPC), ‘Holub [p, green label] // COLL.NIC- KERL / MUS.PRAGENSE [p, with p frame submarginally] // Zambesi [hw] // Diploxys / Holubi [hw] // ♀ [p]’ (pinned through scutellum); 1 ( NMPC), ‘Holub [p] // COLL.NICKERL / MUS.PRAGENSE [p, with p frame submarginally] // [p]’ (glued on small triangular card). All specimens were provided with the following label: ‘topotype, not syntype / DIPLOXYS (Paracoponia) / HOLUBI / Horváth, 1893 / det. P. KMENT 2018’ [p].

Current status. Coponia holubi ( Horváth, 1893) ; type species of the subgenus Paracoponia Horváth, 1893 by original designation (cf. Diploxys (Paracoponia) holubi , HORVÁTH 1893), a junior synonym of Coponia Stål, 1865 (see LINNAVUORI 1982a: 80).

Distribution. Given as ‘Central Africa’ by HORVÁTH (1893) and ‘East Africa’ ( LINNAVUORI 1975). One of the NMPC specimens bears locality label Zambesi, referring to the Zambezi River (flowing through Angola, Zambia, Namibia, Botswana, Zimbabwe and Mozambique). The exact locality is unknown.

Remarks. This species was described based on an unspecified number of female(s) ( HORVÁTH 1893). However, only a single male bearing Horváth’s handwritten type label is found in HNHM; it is reasonable to regard it as part of the original type series even if it conflicts with the sex information provided in the original description; the latter is therefore considered as erroneous. An additional non-type male and two females fitting the original description are deposited in NMPC.

LINNAVUORI (1975: 37) referred to a male (E. Africa, Holub, 1, type, Mus. Budapest) specimen as the type and provided differential diagnosis and drawings based on it. His information contradicts HORVÁTH (1893) but it is in agreement with the fact that the single type specimen present in HNHM is male. We believe that HORVÁTH’ s (1893) mention of female type (s) was a mistake. The action

of LINNAVUORI (1975) must be considered a valid lectotype designation under the Article 74.6 ( ICZN 1999).
