REMARKS

Trimerotropis pallidipennis (Burmeister, 1838) View in CoL (type locality Furnace Creek,Death Valley, California, USA)is the most widely distributed oedipodine in the Americas. It ranges from southwestern Canada to south Argentina ( Otte 1984). Rehn (1939) described the subspecies of T. pallidipennis andeana View in CoL from the high puna areas of Peru,and Otte (1995) in his catalogue of Acridomorpha grasshoppers listed it with specific status. However, Carbonell (2010) still considers it as a subspecies. Rehn (1939) distinguishes T. pallidipennis andeana View in CoL from T. pallidipennis pallidipennis View in CoL based on several characters (i.e., proportionately more robust build, with the head broader, and genae more inflated, eyes less prominent; median carina of prozona lower with bilobation less evident; wing-band is narrow, weak and incomplete; caudal femora stouter), but it has been difficult for us to separate it from materials of T. pallidipennis View in CoL from Argentina. However, a recent phylogeographic study conducted by Guzman & Confalonieri (2010) based on COI sequences from specimens reported herein and from material of T. pallidipennis View in CoL from Argentina and the USA (in total 28 individuals) showed that the specimens from the surveyed region constitute a different genetically haplotype which is more divergent than the specimens from Argentina (Mendoza, San Luis provinces).Future analyses on larger series of specimens of Trimerotropis pallidipennis View in CoL and Trimerotropis andeana View in CoL all throughout its distribution area is needed to clarify the specific and subspecific status of these taxa.
