Pleurophorus caesus distributional records
from southern South America. |
|
|
Original combination: Scarabaeus caesus Panzer, 1796: 2.
Type locality: “Viennae.” |
..... |
|
|
Synonyms: Aphodius angustus Philippi and Philippi, 1864: 316; type locality: “Chilenischen.” Ataenius rugiceps Dury, 1902: 153; type locality: “Cincinnati O.” |
|

Type specimens: Pleurophorus caesus type series not examined. Aphodius angustus neotype at MNNC
labeled: “CHILE: Chacabuco / Colina / 10 November 2003 / J. Mondaca E.” (typeface), “APHODIUS /
ANGUSTUS / PHILIPPI & PHILIPPI / NEOTYPE % / A.B.T.SMITH / P.E.SKELLEY” (handwritten and typeface on red paper), “Southern Neotropical Scarabs / database # AS2599050 / Pleurophorus caesus (Panzer,
/ 1796) / DET: P.E.SKELLEY 2005” (typeface). The location of the type series from Philippi and Philippi’s
original type series is unknown. The type series was presumably deposited in the MNNC along with the
type series of other species described in the same paper. For example, the type series of the Brachysternus Guérin-Méneville and Aulacopalpus Guérin-Méneville species described by Philippi and Philippi (1864) were
all recently located in the MNNC (Jameson and Smith 2002, Smith 2002). However, no type specimens of
Aphodius angustus could be found in the MNNC after numerous searches, nor were any located in the other
collections from which we borrowed material. We can only conclude that the type series has been lost. The
only type locality information given was that the type series was collected in Chile, so a specimen from Chile
was selected as the neotype. Neotype here designated. |

|
|
Specimens examined: 47 specimens were examined from ABTS, FMNH, JMEC, MEUC, MNNC,
PESC, TMSA, UCDS, UMCE, UNSM. |

Distribution: CHILE (47). IV Región de Coquimbo (2): Camino La Serena (Ovalle); V Región de Valparaíso
(1): Villa Alemana; Región Metropolitana (30): Apoquindo, Colina, Colina (Ruta 5 N, km 16.5),
Curacaví (Lingues de Miraflores), El Ingenio, Las Condes (Quinchamali), Rinconada (Maipú), Santiago, Santiago
(El Canelo), Santiago (Ñuñoa), Santiago (Renca); VI Región de O’Higgins (3): Pelequén, San Vicente
de Tagua; VII Región del Maule (6): Linares, Reserva Nacional Los Ruiles (Cauquenes), Talca (20 km S),
Tonlemo; VIII Región del Bío-Bío (1): Río Biobío; No Data (4).
This species was also recorded from Isla Juan Fernández, Chile by Schmidt (1931).
Outside the study area, this species has been recorded from the Nearctic and Neotropics; the Palaearctic;
Africa (Löbl and Smetana 2006). |

Temporal data: January (1), February (2), March (1), May (1), July (2), September (2), October (4),
November (28), December (2). |

Diagnosis: Length 3 mm. See genus diagnosis. The elongate, parallel-sided body is unlike anything else from the study region.

Remarks: Pleurophorus caesus has been introduced in to many part of the world and is considered cosmopolitan.
In the New World, it occurs from Canada to Chile. This species was first reported in Chile by
Philippi and Philippi (1864, as Aphodius angustus).
The authorship of this species is often credited to Creutzer, but it was Panzer (1796) who first described
the species and used the name (even though Panzer credited Creutzer with the name in his original description).
Panzer’s description was his own so he should be the cited author of this name under Article 50.1 of the
rules of zoological nomenclature. |
