Gathocles obliquisignatus: May 1967: 178 . Incorrect subsequent spelling, not available.

Heterargus obliquicostatus: Implied combination based on synonymy of Gathocles with Heterargus in Ślipiński and Lawrence 1997: 385.

Heterargus obliquecostatus: Maddison 2010: 426 . Incorrect subsequent spelling, not available.

Type locality: Otara , Southland .

Broun number: 2767 (as given in May 1967: 178).

Remarks: Broun did not mention the number of specimens examined. Two specimens in the NZAC matching the locality were located. Three specimens in the BMNH matching the locality were located, but one is labeled as a variety and not considered a syntype. This varietal specimen was mentioned in the description as having fewer antennal segments (one side has a few funicle segments fused, but the 2-segmented club exists for both sides). In order to stabilize this name, a lectotype and four paralectotypes are here designated from the material of Gathocles obliquicostatus .

Type material examined: Lectotype ( BMNH): card-mounted, “Type [round label with red border] // 2767. [in Broun’s hand] // New Zealand. [red underline] Broun Coll. Brit. Mus. 1922-482. // Otara. Southland. [in Broun’s hand] // Gathocles obliquicosta. [sic—name abbreviated or perhaps label was cut] [in Broun’s hand]” . Paralectotype ( BMNH): “2767. [in Broun’s hand] // New Zealand. [red underline] Broun Coll. Brit. Mus. 1922- 482. // Var. antenna [in Broun’s hand] // Otara. Southland. [in Broun’s hand]” . Paralectotype ( BMNH): “2767. [in Broun’s hand] // New Zealand. [red underline] Broun Coll. Brit. Mus. 1922-482. // Otara. Southland. [in Broun’s hand] // Gathocles obliquicost. [in Broun’s hand]” . Paralectotypes ( NZAC): 2, individually mounted on separate cards and pins, with identical labels, “Otara Southland [in Brookes’ hand] // Coll. A. Philpott [in Brookes’ hand] // 2767 [in Brookes’ hand] // Gathocles obliquicostatus Broun [in Brookes’ hand] // A.E. Brookes Collection ” .
