Manuscripts considered for publication include, but are not limited to,systematic or taxonomic studies, revisions, nomenclatural changes, faunal studies, book reviews, phylo-genetic analyses, biological or behavioral studies, etc. Insecta Mundi is widely distributed, and refer-enced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc.As of 2007, Insecta Mundi is published irregularly throughout the year, not as a quarterly issues.As manuscripts are completed they are published and given an individual number. Manuscripts must bepeer reviewed prior to submission, after which they are again reviewed by the editorial board to insurequality.

Insect, Coleoptera, Cerambycidae, Tetraopes, new species, keyIntroductionRecent collecting in western South Dakota has yielded a new species of the genus Tetraopes Schoenherr.The new species was discovered while sweeping near Mirror Lakes in Lawrence County.Collection abbreviations listed in text are as follows:  JPHC, Jeffrey P.

Prosternum narrow, feebly impressed at apex, shining, finely, transversely wrinkled, sparselyclothed with yellowish white, appressed pubescence, a few, longer, suberect, pale hairs present; meso- andmetasterna micropunctate, moderately clothed with appressed yellowish white pubescence.  Scutellumdark brown to black scantly clothed with black pubescence.Elytra about 2 times as long as broad, sides parallel; punctures over basal ½ coarse, dense,subcontiguous becoming smaller and less dense toward apex; pubescence moderate, pale, suberect,0008: 1-3 20072 INSECTA MUNDI 0008, April 2007 SKILLMANunderlying pubescence dense, short, appressed, yellowish-white, denser over apical 1/3; humeri black;two black, shining, sutural spots present at about basal ¼, two larger black spots also present at midelytraat beginning of apical 1/3, apices rounded and slightly darkened. Legs long, micopunctate; femoramoderately to densely clothed with yellowish-white, apressesd pubescence, long, pale hairs sparse; tibiaeclothed with yellowish-white, suberect pubescence; tarsi with claws appendiculate.Abdomen densely micropunctate, densely clothed with fine, appressed, yellowish-white pubescence;fifth sternite subtruncate at apex. Length 7.0 - 8.5 mm.Female: Form and color similar to male, but more robust. Front of head strongly convex. Antennashorter. Fifth abdominal segment broadly truncate with small notch at apex (Fig. 3) and impressedlongitudinally at middle extending from base half way to apex. Length 8.0 - 9.8 mmType material. HOLOTYPE male and allotype from U.S.A., South Dakota: Lawrence Co., UpperMirror Lake west end, 23 Aug. 2006, on Asclepias verticillata, J and C Huether (deposited in FSCA).Paratypes (10 males, 4 females): same data as holotype (6); U.S.A. South Dakota: Lawrence Co., MirrorLake fish hatchery NW side, 24 Aug. 2005, J. Huether (3); S.D. Lawrence Co., Mirror Lakes, 24 Aug.2005, R. Turnbow (5). Paratypes deposited in JPHC, RHTC, FWSC, RMBC, EMEC.A single rubbed and greased specimen not included in the type series is labeled: WY: Cook Co., Vic.Entrance Devils Tower Natl. Mnt., 22 Aug. 2006, J. and C. Huether.Whorled milkweed, Asclepias verticillata L.(Fig. 4), is assumed to be the host as all specimenswere swept from this plant. The presumed hostranges into 41 states, including WY. More collectingis needed in this area to help determine the rangeof T. huetheri.Diagnosis. Tetraopes huetheri cannot beconfused with any other described North Americanspecies. The combination of small size, prominentpronotal tubercles, low to moderately elevatedumbone, appendiculate tarsal claws, and lack ofelytral chevron serve to distinguish it.Etymology. This species is dedicated to JeffreyP. Huether who caught the first specimens andprovided the picture of the presumed host.Figure 1-3.
