Chorasus incertus ( Broun, 1895)

( Figs. 93–94 )

Vitiacus incertus Broun, 1895: 195 . Broun 1921a: 530. Hutton 1904: 169. Hudson 1923: 369. Hetschko 1930: 48. May 1967: 178.

Chorasus incertus: Implied combination based on synonymy of Vitiacus with Chorasus in Ślipiński and Lawrence 1997: 368.

Chorasus incertus: Maddison 2010: 426 .

Type locality: Mount Te Aroha .

Broun number: 2774 (as given in Broun 1921a: 530; May 1967: 178).

Remarks: Broun mentioned that he based this species on two specimens collected in March, 1894. Broun (1895: 195) originally listed this taxon as a varietal form of V. costatus to be treated further when more material of both forms became available. Hetschko (1930: 48) also listed it as a variety of Vitiacus costatus Broun. However , V. incertus was listed as a distinct species in later works (e.g. May 1967), thus we regard this species as distinct and not a varietal form. In order to stabilize this name, a lectotype and paralectotype are here designated from the material of Vitiacus incertus .

Type material examined: Lectotype ( BMNH): card-mounted, “Type [round label with red border] // 2774. [in Broun’s hand] // Mount TeAroha. [in Broun’s hand] // New Zealand [red underline] Broun Coll. Brit. Mus. 1922- 482. // Vitiacus incertus . [in Broun’s hand]” . Paralectotype ( BMNH): mounted venter-up, “2774 [in Broun’s hand] // Mount. Te Aroha [in Broun’s hand] // New Zealand [red underline] Broun Coll. Brit. Mus. 1922-482. // Vitiacus incertus [in Broun’s hand]” .
