(type locality: fiji, Gau Island, 17.98ºS, 179.27ºE)and Laniferus grandis Waqa & lingafelter, n. sp. (type locality: fiji, viti levuisland, 17.58ºS, 178.08ºE).INtroduCtIoNin this work we describe two species of Callidiopini from fiji in the genera Ceresium andLaniferus. the tribe Callidiopini of the subfamily Cerambycinae contains more than tengenera. the largest of these is the genus Ceresium, containing 109 species and subspecies(encyclopedia of life, 2008). Most of the diversity of Ceresium is found in asia and thePacific islands, but the genus is widespread with some species also occurring in africaand australia, and several dubious records from north america and the Caribbean.including the species described herein, seventeen species are known from fiji (dillon &dillon, 1952; Bigger & Schofield, 1983; evenhuis, 2007). Contrasting from Ceresium, thegenus Laniferus was known from only one species, L. uniformis dillon & dillon (1952),prior to this work. MAtErIALS ANd MEtHodSMuch of the material in this work originates from the extensive Malaise trap collectionsfrom the nSf – fiji terrestrial arthropod Survey (evenhuis & Bickel, 2005). Material isdeposited in the Smithsonian institution, Washington, dC (USnM), Bishop Museum,Honolulu, Hawaii (BPBM), and the fiji national insect Collection, Suva, fiji (fniC), andthese acronyms are used hereafter. label data is verbatim, therefore some information isoccasionally presented in inconsistent formats.1.

(1 [sex indet.]).diagnosis and discussion. this species of Ceresium is easily recognized by the promi-nent anterolateral pronotal tubercles making the pronotum wider anteriorly than posteri-orly (almost all species of Ceresium have the pronotum broader posteriorly or subequal inwidth at posterior and anterior margins); the prominent, broad, ventrally projecting, acute-ly declivous prosternal process (nearly all Ceresium have a very narrow, graduallydeclivous prosternal processes); prominent, anteriorly right-angled mesosternal process;sparsely pubescent, shiny elytra with sparse, widely separated punctures and scatteredpubescent aggregations (most Ceresium have elytral pubescence denser and more uni-form). With regards to the pronotal proportions, C. tuberculatum is most similar to C.guttaticolle, but in that species the pronotum has dense patches of pubescence anteriorlyand posteriorly.Fiji Arthropods–XV: Waga & Lingafelter—New Fiji Cerambycidae 5Figure 1.

Laniferus uniformis is known onlyfrom Ovalau island while L. grandis is known only from viti levu island.Etymology. the specific epithet, grandis, is a latin adjective referring to the large size ofthis species.BISHOP MUSEUM OCCASIONAL PAPERS: No. 106, 200910Fiji Arthropods–XV: Waga & Lingafelter—New Fiji Cerambycidae 11Figure 6.
