INSECTA MUNDI, Vol. 12, Nos. 1 & 2, March-June, 1998 139 Redeseriptions, new combinations, synony~es,and new records of South American Lepturini (Coleoptera: Cerambycidae: Lepturinae) Osvaldo R. Di Iorio Entomologia, Facultad de Ciencias Exactas y Naturales, 1428 Ciudad Universitaria, Buenos Awes, Argentina. Internet: [email protected] Abstract: Some Neotropical Lepturini are studied: Euryptera latipe~znis Audinet-Serville, 1828 (type species) redescription, Strangalia dirnidiata (Redtenbacher, 1868) new combination (= Stra~zgaliarnelarzophthisis (Berg, 1889) new combination, new synonymy, and lectotype designation), Strangalia fulvicornis (Bates, 1872) new record from Argentina; Strangalia rnelarzura (Redtenbacher, 1868) new combination from Brazil; Strarigalia rubricollis (Bates, 1870) new record kom Peru. "Leptura" bor~arierzsisBurmeister, 1865 is not a true Leptura, being exotic for Argentina and for the Neotropical fauna; the type-specimen was mislabelled as coming from Buenos Aires. Elytral patterns, posterior tarsi, antennae, 5th apparent urosternite, and elytral apices of E. latipelanis, and S. dirnidiata are illustrated. A key to Argentinian genera and species is provided. Key words: Coleoptera, Cerambycidae, Lepturini, systematics. Introduction Facultad de Humanidades y Ciencias, Montevideo, Uruguay; GP: Glorialdo Pellerano (MACN); MACN: Lnsley & Chemsak (1971) characterized the Museo Argentino de Ciencias Naturales "Bernar- genera Euryptera Audinet-Serville, 1828 (type din0 Rivadavia," Buenos Aires; MLP: Museo de La species E. latipelutis Audinet-ServiUe, 1828) and Plata, Buenos Ares; ODI: Osvaldo Di Iorio, Buenos Straltgalia Audinet-Servrlle, 1828 (type-species Awes; MV: Manuel Viana, Rosario de Lerma, Salta; Leptura luteicorltis F.: Thomson, 1860 designation), MZ: Mateo Zelich, Liebig, Entre Rios. and transferred many Central American species from Euryptera to Straltgalia. The revision of the Euryptera Audinet-Serville, 1828 North American fauna of Lepturinae, started by Linsley and Chemsak (1972), was completed in 1976 Type-species: E. latipeltnis Audinet-ServiUe, by the same authors, who included Strangalia and 1828 (by monotypy). Leptura among the genera with the sides of the Diagnosis (from Linsley and Chemsak, 1971): prothorax inerm. elytra more or less flattened, costate, expanded Within the South American fauna, not all the posteriorly; apices transversely sinuate; sutural and species originally described in Euryptera and still external angles dentiform (Fig. 6); prosternal placed in this genus (Monn6 and Giesbert, 1995) process narrow, more or less laminiform, arcuately belong to it. Of the 3 species recorded for Argentina, declivous behnd; coxae exerted, extending well Euryptera latipennis, Euryptera dilnidiata Red- above the intercoxal process; mesosternal process tenbacher (1868) and Euryptera rnelartophthisis prominent, elevated above the coxae, arcuately but Berg (1889), the last 2 belong in the genus subvertically declivous in front. Strangalia, the last being a synonym of the second. One new record of species of Strangalia for Euryptera latipennis Audinet-Serville, 1828 Argentina is added here, the first species of this (Figs. 1, 5-6, 8, 11-13, 27) genus is recorded for Per&, and the diagnosis of the genus Euryptera is amplified.

Elytra slightly narrowed behnd Taxonomic discussion: Linsley and Chemsak humeri, behind this, lateral margins diverge (1971) give more characters for Stralzgalia than for gradually backward, broadening on apical 114 (Figs.

To the genus diagnosis triangular spine; posterior margin truncate, first (Linsley and Chemsak, 1971), the following outwardly concave and then inwardly convex; characters are added, different from Stralzgalia: 111 sutural angle straight, slightly projecting (Fig. 6). antennomere slightly shorter than scapus (Fig. 1); Elytra with 5 costas, not reaching anterior and hnd tibiae not carinate, not exceeding the posterior posterior margins of each elytron; 3 very weak margin of elytra; first segment of hind tarsus twice veins, which coincide with first, second, and fourth as long as the second and third taken together (Fig. costae, counting from suture. 5); posterior angles of the prothorax going round the Prosternal process little less strongly raised humeri; posterior margin of the pronotum strongly than fore coxae (globose, prominent), strongly convex on the median line; elytra with 5 costae; narrowed between these and backward, not ex- posterior angles of the 5th apparent urosternite ceedmg posterior margin of coxae; mesosternal strongly projecting (Fig. 8). process slightly raised above middle coxae, with Biogeography: distribution of E. latipe7tlzis anterior margin subvertical. covers from the north-east and central-east of Brazil Urosternites subequal in length, gradually (Zajciw, 1958, 1972, 1973) to Paraguay (Viana, narrowing backward, with setigerous punctures 1972), and from there along the Yungas in Bolivia, evenly spaced; posterior margin straight in first 3 and the northwest of Argentina (material
