Xanthopimpla peruana Krieger 1914

(Figs. 5 d, 6d, 7d)

Original description. See Krieger (1914).

Re-description in English. See Townes (1969).

Diagnosis. Xanthopimpla peruana can be distinguished from all other Neotropical species by the combination of the following characters: 1) occipital carina complete, rather weak dorsally; 2) propodeum with reduced carination, with only posterior transverse carina present (Fig. 1 f); 3) triangular crests at the anterior edge of the mesoscutum small (Fig. 1 c); 4) ventrolateral carina complete across the length of the first tergite (Fig. 1 i); and 5) body almost entirely lemon yellowish.

Remarks. The Andean species X. peruana is established as an unplaced species outside of the aurita and amazonica species-groups. It may be possible to place it into a new species-group in the future after the tropical Andes become better sampled.

Distribution. Ecuador, Peru.

New material examined. Peru: Female (UNSM): Dept. of Cusco, Cosñipata, 13°03’ S, 71°32’ W, 1500 m. Castillo leg, Hand net. X.2007. Female (ZMUT): as above but IX.2007. Male (ZMUT): as above but IX.2008. Male (ZMUT): as above but IX.2007.

Notes. The species seems to be the only Neotropical Xanthopimpla restricted to the tropical Andes at about 1200–1500 m above sea level.
