Mecistocephalus ongi Takakuwa, 1934b

[Japanese name: On-nagazujimukade]

Mecistocephalus ongi Takakuwa, 1934b: 360–362 , figs 9, 10 (available name); Verhoeff 1939: 86.

Mecistocephalus ongi Takakuwa, 1934c: 884 (list).

Mecistocephalus ongi Takakuwa, 1934d: 221–222 , fig. 1 (invalidly described as new); Takakuwa 1942: 17; Uliana et al. 2007: 44–45, fig. 53.

Mecistocephalus ongi (without attribution): Takakuwa 1940a: 69–70, fig. 65; Attems 1947: 100, 101 (key); Shinohara et al. 2015: 908 (key).

Type series. No types were designated in Takakuwa (1934b –d), although Takakuwa (1934b, d) imply that the descriptions were based on multiple specimens. None of the two syntypes reported by Takashima (1955) could be found in the Miyosi Collection by the authors, and thus they may have been lost.

Type locality. Tainan City, Taiwan .

Japanese name. The name “On-nagazujimukade” was introduced by Takakuwa (1934b).

Remarks. The authorship of this species in ChiloBase 2.0 (Bonato et al. 2016e), currently given as Takakuwa (1934d), should be corrected to Takakuwa (1934b).

This species was cited as “ M. ongi Takakuwa, 1932 ” in Murakami (1993). As was noted in connection with M. brevisternalis above, a misdated reprint may explain why Takakuwa (1940a) erroneously cited Takakuwa (1934d) as “ Takakuwa (1932) ” and the reason for the error in Murakami (1993).

Type series. No types were designated in Takakuwa (1932), and this work has no implication of the composition of the original material. Takakuwa (1934a) did neither designate types nor indicate the composition of the material. According to Moritz and Fischer (1979), two specimens traditionally treated as “ syntypes ”, examined by Verhoeff (1934), are preserved at the Museum of Natural History, Berlin.

Type locality. Although Takakuwa (1932) did not refer the type locality, he stated that this species was common in Tokyo and adjacent areas, and also found in “ Akita, Hyogo, Ehime and so forth” . Takakuwa (1934a) listed “ Tokyo and adjacent area”, “ Akita City” (in Akita Prefecture), “Sanda, Hyogo Prefecture ”, “Imabari City” (in Ehime Prefecture), “ Izu-oshima Island ”, “ Hiroshima City” (in Hiroshima Prefecture), “Toshita (possibly in Aso District ), Kumamoto Prefecture ”, “ Oita City” (in Oita Prefecture) as the localities . Verhoeff ’s (1934) description was based on 10 specimens from “ Umgebung von Tokyo ” (=vicinity of Tokyo) .

Japanese name. The first appearance of a Japanese name was in Takakuwa (1932), as “Takakuwa-jimukade”, modified to “Takakuwa-nagazujimukade” in Takakuwa (1934a) while also appearing as “Takakuwa-jimukade” in the captions of the latter work’s figs 1, 2, and 8–10. Takakuwa (1938b) shortened the new spelling to “Taka-nagazujimukade”, which is the form used in subsequent publications (e.g., Takakuwa 1939a, b, 1940a; Murakami 1993) and by us.

Remarks. ChiloBase 2.0 (Bonato et al. 2016o) cites Verhoeff (1934) as the author of the specific name takauwai; this should be corrected to Takakuwa (1932). Uliana et al. (2007) synonymized this species with M. diversisternus ( Silvestri, 1919) .
