Brontoliota lawrencei Thomas, new species, is described and illustrated from Chile, and the Chileansilvanid fauna is discussed.IntroductionThe New World has relatively few representatives of the silvanid tribe Brontini. A recent genericrevision of the tribe (Thomas 2004) recorded just two genera, Uleiota Latreille and Dendrophagus Schönherr,from North America with a total of four species, and two from Chile, Australohyliota Thomas andMicrohyliota Thomas, with a total of two species. Recently, a species of Parahyliota Thomas, a hithertoAsian and African genus, was described from Mexico (Thomas 2009). In this paper, I describe a newspecies of Brontoliota Thomas from Chile. Brontoliota was described (Thomas 2004) for three speciesendemic to northeastern Australia. All photographs were taken with a Syncroscopy AutoMontage® sys-tem attached to a Leica Z16 APO microscope.Brontoliota lawrencei Thomas, new speciesFigure 1-6Diagnosis. From other brontine genera present in Chile, Brontoliota is easily distinguished by itsflightlessness, body incrustation, and bud-vase-shaped antennal scape. From other members of Brontoliota,the new species is distinguished by having four lateral projections on the pronotum (versus six or seven inthe Australian species).Description. Holotype male, deposited in the Museo Nacional de Historia Natural, Santiago, Chile, withthe following label data: “CHILE: Punta Curiñanco (39o42.788S, 73o24.323W) 177m 9.i.2007 Aextoxicumforest, under bark & in rotten logs J.F.

Length, 8.7mm.Head transverse, markedly triangular in shape, widest across the densely setose, pronounced temples;frons above antennal insertions strongly elevated, densely punctate and setose, with a strongly impressed,curved, transverse groove between antennal insertions; surface otherwise appearing almost impunctate;surface smooth and shining, without microsculpture; with scattered thick, strongly curved, suberectsetae, denser laterally and especially so along margins; eyes small, protuberant, set on short stalks;antennae filiform, about two-thirds length of body; scape as long as head, slightly sinuate, shaped like abud-vase, densely, coarsely punctate; ratios of antennomeres 5.5:1:1.5:2.5:2.5:2.5:2.5:2:2:1.7:2.Pronotum (Fig. 4) 1.28 × wider than long, more or less bluntly triangular in shape, widest at front,with four blunt lateral processes, the first long and relatively slender, the following three shorter; disksimple, slightly concave medially; appearing almost impunctate; surface smooth and shining, withoutmicrosculpture; with scattered thick, curved, suberect setae; setae denser laterally and especially soalong margins.Elytra 2.4 × longer than wide, basally narrowed, forming a neck-like region, then broadened andparallel-sided to about apical fifth, where they narrow to rounded apices; apices not individually produced;2 • I NSECTA M UNDI 0113, January 2010 THOMASFigure 1.

Hind wingsabsent; metaventrite very short.Male genitalia (Fig.6) with apex of median lobe deeply, moderately broadly emarginate.The female allotype (Fig.2), deposited in the Essig Museum, University of California, Berkeley, withsame data as holotype, is similar to the male, differing as follows: Head 1.33 × wider than long, widestacross eyes; antennae slightly shorter than in male.

This species is named in honor of JohnF. Lawrence, its collector, in acknowledgment ofhis many important contributions to knowledge ofthe Coleoptera during his long career.Discussion. Punta Curiñanco is located in theValdivian Coastal Range in southern Chile, thearea of highest endemism in Chile (The NatureConservancy 2009). Chile has a curious silvanidfauna. Two of the Chilean brontine gene-ra,Brontoliota and Australohyliota, have speciesin both Chile and Australia, while the monotypicMicrohyliota is found in Chile exclusively.Brontoliota and Australohyliota do not appear tobe especially closely related. The only other silvanidknown from Chile is Australophanus redtenbacheri(Reitter), a member of the tribe Telephanini (Tho-mas and Nearns 2008). The entire subfamilySilvaninae is apparently absent from Chile, al-though well represented in the rest of SouthAmerica and in Australia.AcknowledgmentsI thank especially John Lawrence for makingthese specimens available for description.
