Blennidus (Agraphoderus) nigritulus Straneo 1993

Abstract

<i>Blennidus</i> (<i>Agraphoderus</i>) <i>nigritulus</i> (Straneo, 1993) <p>(Figs. 32, 70, 106)</p> <p> <i>Ogmopleura nigritula</i> Straneo, 1993: 383</p> <p> <i>Blennidus nigritulus</i> (Straneo, 1993): Lorenz, 2005a: 263 <i>Blennidus nigritulus</i> (Straneo, 1993): Lorenz, 2005b: 681 <i>Blennidus nigritulus</i> (Straneo, 1993): Giachino & Allegro, 2011: 23</p> <p> <b>Type locality.</b> The ♂ HT is labelled, in Straneo’s own hand, “loc. 14”, which likely means, by analogy with all other specimens of TS and according to Straneo (1993), “ Perou, 30 km S Cerro de Pasco, 4150 m ”.</p> <p> <b>Examined material.</b> HT ♂ (CMa at MRSN); 4 PTT ♂ and 3 PTT ♀ (CMa, CSt); 1 ♂ (CMa). One PT ♂ in CMa actually belongs to <i>B. curtatus</i>. One specimen of <i>B. nigritulus</i> is included in the TS of <i>angularis</i> Straneo, 1985 (= <i>B. rectangulus</i> <b>syn. nov.</b>) (CMa) and 6 others in the TS of <i>B. rectangulus</i> (Straneo, 1993) (CMa, CSt).</p> <p> <b>Note.</b> This species is mainly distinguished by the distinctive morphology of aedeagus, as it is very similar in external morphology to a few species from central Peru (<i>B. rectangulus</i>, <i>B. euphaenops</i>, <i>B. vereshaginae</i>, etc.). An aedeagus of <i>B. nigritulus</i> is attached on separate cards by two specimens of <i>B. inca</i> (CMa, CSt), due to an evident label inversion.</p> <p> <b>Distribution.</b> All the recorded specimens are from the same area (30 Km South of Cerro de Pasco), which is probably a border area between Depts. Pasco and Junin.</p> <p> <b>Habitat.</b> The altitude data reported on the labels (4,150 m a.s.l.) suggest a preference of this species for the Andean grassland.</p>Published as part of <i>Allegro, Gianni & Giachino, Pier Mauro, 2015, Annotated checklist of the Blennidus subgenus Agraphoderus species from Peru with description of B. bombonensis n. sp. and synonymic notes (Coleoptera: Carabidae: Pterostichinae), pp. 1-48 in Zootaxa 4000 (1)</i> on page 13, DOI: 10.11646/zootaxa.4000.1.1, <a href="http://zenodo.org/record/289219">http://zenodo.org/record/289219</a&gt
