Translated by J. C. Watt (Auckland) [Received by the Editor, February 19, 1962.]

Abstract

Keys to all known New Zealand species of the following genera and a key to the genera (grouped provisionally as Acanthocinini) are presented, and each genus and species is described: Tetrorea White (4 spp.); Polyacanthia Montr. (1 sp.); Mesolamia Sharp (2 spp.) ; Metalamia Breun. (2 spp.); Microlamia Bates (2 spp.); Stenellipsis Bates (16 spp.); Trichocnaeia Breun. (1 sp.); Hybolasiopsis Breun. (1 sp.)i Poecilippe Bates (4 spp.); Hybolasius Bates (28 spp.); Hybolasiellus Breun. (1 sp.); Spinohybolasius Breun. (1 sp.). The 63 species included constitute about one-third of the New Zealand cerambycid fauna.

Translator's Note

The manuscript of the present paper was received from Dr Breuning for translation and publication in a New Zealand journal. In translation the main object has been to present, in English, the exact meaning of the French. Where the meaning of a word or phrase has been in doubt for any reason, the description has been checked against specimens in the Auckland Museum Collection. No technical terms not used in the original have been introduced.

Four subfamilies of Cerambycidae have representatives in New Zealand. A key to the subfamilies of longhorn beetles may be found in Crowson (1955: 139-41).

The subfamily Prioninae contains a single New Zealand species, Prionoplus reticularis White. The New Zealand members of the Lepturinae and Cerambycinae were listed by Blair (1937).

The subfamily Lamiinae includes the remaining two-thirds of the New Zealand cerambycid fauna. The Parmenini, containing New Zealand species of the genera Xylotoles Newm. (21 spp.), Xylotoloides Breun. (1 sp.), Adriopea Broun (1 sp.), Somatidia Thoms. (41 spp.), Corestheta Pasc. (2 spp.) and Hexatricha Thoms. (1 sp.), have been covered elsewhere (Breuning, 1950). The present paper describes the remainder of the New Zealand Lamiinae. The larvae of 20

New Zealand species of Cerambycidae were described by Dumbleton (1957). Two species of Acanthocinini, namely Tetrorea cilipes White and Hybolasius genalis Broun are included.

The systematic list indicating type localities and the location of type specimens has been compiled from information supplied by Dr Breuning. The remainder of the paper is a direct translation of the French manuscript, the only alterations being to incorrectly spelled place names.

The term “ morpha ” is in most cases equivalent to “ variety ”, although some morphae may eventually be found to be worthy of recognition as geographical subspecies.

All localities included above are listed in the gazetteer of “A Descriptive Atlas of New Zealand” (McLintock, A. H. (editor), 1959) and may be thus located. In a few cases the exact locality where the type was collected is not known. In such species it may eventually be desirable to fix a more specific type locality when sufficient material has been collected and studied.

Tribe ACANTHOCININI

The Lamiinae of New Zealand may be divided readily into two groups:

1. All the genera with metastemum very short. I have covered these in my revision of the Parmenini (Breuning, 1950). 2. All the genera with metasternum of normal length or more or less slightly shortened, which I treat below, grouping them all together provisionally under the name of Acanthocinini (described in my revision of African Acanthocinini: Breuning, 1958 and 1959).
