Genus Dicellophilus Cook, 1896

Dicellophilus latifrons Takakuwa, 1934a [Japanese name: Hirozu-jimukade]

Mecistocephalus pulcher Kishida, 1928: 300–303 (as Mecistocephalus pulcher Kishida, 1925 [sic]) (senior subjective synonym).

Dicellophilus latifrons Takakuwa, 1934a: 707 (key; available name).

Dicellophilus latifrons Takakuwa, 1934b: 355–356 , figs 1–3 (invalidly described as new); Takakuwa 1940a: 82–83, figs 84, 85; Attems 1947: 103 (key); Takashima and Shinohara 1952: 8, 14 (key).

Dicellophilus latifrons Takakuwa, 1934c: 878–879 , figs 13–15 (invalidly described as new); Bonato et al. 2003: 550, 551, 575, fig. 13.

Dicellophilus latifrons (without attribution): Takakuwa in Kishida and Takakuwa 1949: 936, fig. 2675; Miyosi and Takakuwa 1971: 737.

Dicellophilus pulcher: Uliana et al. 2007: 27–30 , figs 32–35 [ Kishida (1928) cited as original description, with authorship of latifrons attributed to Takakuwa (1934b)]; Bonato et al. 2010: 524, 525, figs 5–9, tables 1, 3 [ Kishida (1928) cited as original description, with authorship of latifrons attributed to Takakuwa (1934b)]; Shinohara et al. 2015: 895, 909, fig. 9 (895) (no attribution).

Type series. No types were designated in Takakuwa (1934a –c), but since seven localities are listed by Takakuwa (1934b, c), there must have been originally at least seven syntypes. None of the five syntypes reported by Takashima (1955) could be found in the Miyosi Collection by the authors, and thus may have been lost.

Type locality. No localities were stated in the original description ( Takakuwa 1934a). Takakuwa (1934b) listed following sites as the localities of this species: “Kaibara (Hyogo)” (currently in Tamba City, Hyogo Prefecture), “Masudo (bei Tokyo)” (possibly misread of Masuko Village, currently in Akiruno City, Tokyo), “Komono (Miye)” (= Komono Town, Mie Prefecture), “Ikao (Gumma)” (= Ikao Township Shibukawa City, Gunma Prefecture), “Ōta (Gumma)” (=Ota City, Gunma Prefecture), “Odawara (Kanagawa)”, and “Suwa (Nagano)” .

Japanese name. Takakuwa (1934c) introduced the Japanese name “Hironagazu-jimukade” for D. latifrons , subsequently cited as “Hirozu-jimukade” ( Takakuwa 1938b, 1939a, 1940a; Murakami 1993). Shinohara et al. (2015) gave “Hirozu-jimukade” as the Japanese name for D. pulcher (see below).

Remarks. In ChiloBase 2.0 (Bonato et al. 2016a), the authorship of the nominal species D. latifrons , now incorrectly cited as Takakuwa (1934b), should be corrected to Takakuwa (1934a). Uliana et al. (2007) synonymized this species with D. pulcher , which had originally been described as “ Mecistocephalus pulcher Kishida, 1925 , n. sp. ”, with the Japanese name “Oyama-jimukade”. Uliana et al. (2007) suggested that 1925 may refer to the year when the holotype was collected.
