Caccomolpus hallianus Broun, 1917

Caccomolpus hallianus Broun, 1917:466 . Type locality: Mount Dick.

Comments. Broun based this species on four specimens collected from Mount Dick (Lake Wakatipu), one a female collected on 29 January 1914, and “three others” collected on the same mountain for “two days” in March by T. Hall. There were four specimens in the Broun collection (BMNH), two collected from 29 January 1914 and two collected on 13 March 1914. There were two additional specimens in the NZAC on 13 March 1914 collected from Mt Dick and labelled as syntypes by Robin Craw, and an additional four specimens labelled as “var. 3964” by Broun, two of which lacked locality information, and two from Ben Lomond. Unfortunately, Broun may have confused dates and localities, or there was mislabelling by Broun, or label switching in the Broun material because two male specimens in the BMNH were labelled as “var. 3966” a number corresponding to C. substriatus described from Ben Lomond (Dunedin) but had the Mt Dick locality labels and were collected in March. Note that these species, and others, are considered synonymous by M. Daccordi (pers. obs.) with C. pullatus . We decided to treat two BMNH specimens collected in January 1914 as syntypes, and designate the male as the lectotype and the female a paralectotype.

Type material examined. Lectotype ( BMNH): re-mounted on card with removed aedeagus mounted at corner [left antenna, right antennomeres A7–11, left protibia, left hindleg, right protarsomeres 4 and 5, most of the right tibia, and hind tarsus missing], “3964. ♂.
