The Ochteridae of Ecuador, with new records and an identification key (Hemiptera: Heteroptera: Nepomorpha) Author Cianferoni, Fabio text Zootaxa 2012 3260 62 68 journal article 10.5281/zenodo.210038 4734e2c2-a8ad-43ba-be36-e32ae0225b8f 1175-5326 210038 Ochterus viridifrons ( Champion, 1901 ) Material examined. Ecuador , Pichincha province, La Unión del Toachi, Toachi river right tributary, 850 m amsl, 28.VI.2009 , 1 Ƥ, legit F. Cianferoni, C. Monte & F. Zinetti, coll. CFC Notes. This female specimen matches Champion’s description well. A close species with a metallic green frontal plate is O . schellae Drake, 1952 , which has straight lateral margins of pronotum ( Schell 1943 sub O . acutangulus ; Drake 1952 ) and not clearly arched as in O . viridifrons ( Champion, 1901 ) . O . acutangulus ( Champion, 1901 ) doesn’t match because of the distinctly acute humeral angles of pronotum (see the female figured in Drake 1952 ), while in this specimen the “lateral angles subacute” are clearly notable ( Champion 1901 ). Finally O . hungerfordi Schell, 1943 distinctive characteristics are brown labium and rostrum and not lemon yellow as this specimen. O . rotundus Polhemus & Polhemus, 1976 (with yellow labrum and rostrum too) replaces O . viridifrons in the Gran Canyon area ( Stevens & Polhemus 2008 ). The record, first for South America (cfr. Heckman 2011 ), must however be confirmed by male specimens.
