Río, M. Guadalupe Del & Lanteri, Analía A., 2018, New synonymies, new combinations and lectotype designations for weevils in the tribe Naupactini (Coleoptera: Curculionidae: Entiminae), Zootaxa 4500 (3), pp. 329-340 : 335-336

Naupactus cyphoides ( Heller, 1921)

Archopactus cyphoides Heller, 1921: 24 . Type material: lectotype female herein designated; Argentina, Tucumán, XI–1899, Bruch leg; SMT, Dresden. Length: 12 mm; grey and brownish vestiture ( Fig. 17 ).

Archopactus griseomaculatus Hustache, 1923: 280 (originally described as a variety of A. cyphoides ). Type material: lectotype female herein designated; Argentina, Chaco de Santiago, Río Salado ; MNHN, col. Hustache. Length: 12 mm; grey and brownish vestiture.

Naupactus cyphoides: Dalla Torre, Emden & Emden, 1936: 18 ; Wibmer & O’Brien, 1986: 59.

Naupactus prasinus Hustache, 1947: 44 , 65 (originally described as a variety of N. cyphoides ). Type material: holotype female; Argentina, Chaco de Santiago, Río Salado , C. Bruch; NMNH, col. Hustache. Length: 10 mm; green, scaly vestiture not uniform.

Naupactus viridimarginalis Hustache, 1947: 43 , 65 (originally described as a variety of N. cyphoides ). Type material: lectotype female herein designated; Argentina, Chaco de Santiago, Río Salado ; NMHN, col. Hustache. Length: 13 mm; almost naked (lacking scales), with pair of green marginal stripes along sides of pronotum and elytra.

Naupactus calamuchitanensis Hustache, 1947: 65–66 . Type material: lectotype male herein designated; Argentina, Córdoba, El Sauce , Dto. Calamuchita, XII–1938, MJ Viana; at MNHN, col. Hustache. Length: 8.5 mm; naked (lacking scales) except for two pairs of green stripes (dorsal and marginal) along pronotum and elytra ( Fig. 18 ). New synonymy.

Naupactus viridinitens Hustache, 1947: 66 . Type material: lectotype female herein designated; Argentina, Chaco de Santiago, Río Salado ; MNHN, col. Hustache. Length: 13.5 mm; uniformly green, with pinkish stain on dorsum of pronotum, legs and venter ( Fig. 19 ). New synonymy.

Naupactus viridulus Hustache, 1947: 66 . Type material: lectotype female herein designated; Argentina, Chaco de Santiago, Río Salado ; MNHN, col. Hustache. Length: 9 mm, vestiture sparse, with two pairs of green stripes (dorsal and marginal) along pronotum and elytra ( Fig. 20 ). New synonymy.

Geographic distribution: North–Central Argentina (Buenos Aires, Córdoba, Chaco, Formosa, La Rioja, Rio

Negro , San Luis , Santa Fe , Santiago del Estero and Tucumán ), Bolivia ( Tarija ), Paraguay ( Capital and Presidente Hayes) and Uruguay (Río Negro). Paraguay is a new country record. (female from Asunción, IX-1922 to IV- 1923, EG Kent, BMNH) .

Remarks: Naupactus cyphoides shows several morphotypes that occur in sympatry in north-central Argentina, especially in Santiago del Estero province (Chaco de Santiago sensu Hustache ), along the gallery forest of the Río Salado. Males are more slender and smaller than females, and they are absent or scarce in some populations. Herein we establish three new synonymies and we designated five lectotypes (for N. griseomaculatus , N. viridimarginalis , N. calamuchitanensis , N. viridinitens and N. viridulus ). The only specimen labeled as type, within the type series of each nominal species, was selected as lectotype and the remaining specimens of the series are paralectotypes. Moreover, there are paralectotypes in two Argentinean collections, MLP ( Naupactus viridimarginalis , see Morrone & Loiácono, 1992) and MACN ( Naupactus cyphoides and N. griseomaculatus , see Bachmann & Lanteri, 2013).
