Agrianome howei ( Olliff, 1889) stat. nov.

( Figs. 2 A–D, 16 A)

Cnemoplites howei Olliff, 1889: 95 . TL: Lord Howe Island. Neotype in ANIC (designated here).

Agrianome spinicollis howei: Lameere, 1912, 1913 , 1919; McKeown 1947.

Diagnosis. A. howei can be separated from other Agrianome species by the antennomere 3 as long as or slightly shorter than antennomeres 4 and 5 combined; pronotum with strongly emarginate anterior margin; protibia without lateral spines and being geographically restricted to the Lord Howe Island.

Notes. When reviewing the insect fauna of the Lord Howe Island, Olliff (1889) found a large Prioninae species he assumed to be Arimaspes howei Thomson (currently in Hermerius ) described from that island. Based on the locality alone Olliff (1889) catalogued this species as Cnemoplites howei (Thomson) , and commented the specimens he had at hand were apparently similar to Agrianome gemella Pascoe. After examination of the type specimens of Arimaspes howei Thomson , Agrianome gemella Pascoe and available specimens from Lord Howe Island, we found the following: (a) all Lord Howe Island Macrotomini belong to a single species of Agrianome ; (b) Arimaspes howei Thomson belongs to Hermerius and its type locality of Lord Howe Island is most probably wrong; (c) Olliff (1889) had specimens of Agrianome from Lord Howe Island that he misidentified as Arimaspes howei Thomson , and his comments on his specimens were diagnostic enough to treat them as species description. However, the specimens Olliff examined at that time (obtained by Mr. Etheridge’s party) were probably lost (D. Smith, pers. comm.) and a neotype of Cnemoplites howei Olliff is therefore designated here to stabilise the taxonomic status of the species.

Type. Cnemoplites howei Olliff , neotype here designated: a male specimen deposited in ANIC with the following labels: “ Lord Howe Island, 1957, I. Liepa | ANIC Database 25-039504” (genitalia were dissected and stored separately, and the right hind coxa was used for DNA extraction).
