Epigean Tenebrionids (Coleoptera: Tenebrionidae) from the Choros Archipelago (Coquimbo Region, Chile)

Abstract: Using pitfall traps, we studied the taxonomic diversity of epigean tenebrionids in the Choros Archipelago, formed by the Choros, Damas and Gaviota Islands, which are part of the Pingüino de Humboldt National Reserve. We identified fourteen species arranged in eight genera and six tribes, of which seven species were common to the archipelago. Five genera are reported for the first time as occurring in insular habitat islands: Psectrascelis Solier, Entomochilus Solier, Diastoleus Solier, Scotobius Germar, and Th… Show more

“…We consider that our findings have important consequences for the setting of conservation priorities. Taking into account that tenebrionid species with limited distributions allow greater likelihood of extinction (Alfaro et al 2009), the areas of micro-endemism represent sites of higher significance to conservation than those identified as hotspots. Nonetheless, some cells shared the hotspots and micro-endemism conditions in our study, making it difficult to determine their rank in terms of conservation.…”

“…Esta área pertenece al SNASPE (Sistema Nacional de Áreas Silvestres Protegidas del Estado) y está formada por las islas Choros, Damas y Chañaral (CONAF 1997). Diversos estudios de artrópodos se han realizado en estos sistemas insulares, entre ellos la descripción de especies endémicas (PizarroAraya & Flores 2004;Ojanguren-Affi lastro et al 2007;Grismado & Pizarro-Araya 2016), estudios ecológicos sobre la estructura comunitaria de insectos epigeos (Alfaro et al 2009(Alfaro et al , 2016Pizarro-Araya et al 2014a), Scorpiones (Arachnida) (Pizarro-Araya et al 2014b), estudios de las variaciones morfológicas de coleópteros tenebriónidos (Benítez et al 2014), caracterización de las comunidades de Solifugae (Arachnida) en islas y áreas continentales adyacentes (Valdivia et al 2008(Valdivia et al , 2011 y evaluación de estados de conservación PizarroAraya et al 2017). A la fecha no se dispone de estudios que evalúen los niveles de riqueza y los esfuerzos de muestreo de artrópodos de áreas insulares.…”

“…La mayor parte de las investigaciones se han realizado en las áreas continentales, y sólo unas pocas se han realizado en áreas insulares. En estas áreas insulares se han descrito varias especies endémicas (Pizarro-Araya & Flores 2004;Ojanguren-Affi lastro et al 2007a;PizarroAraya et al 2012a), se ha analizado el ensamble de tenebriónidos epígeos (Alfaro et al 2009) y sus variaciones morfológicas (Benítez et al 2014) y se ha comparado la fauna de Solifugae (Arachnida) entre las áreas insulares y continentales aledañas (Valdivia et al 2011).…”
