TYPE MATERIAL: PERU: Apurímac Department: Abancay Province: Holotype ♂ (MUSM), Tamburco, Sector Arapato, Santuario Nacional Ampay, 13 ° 359S 72 ° 529W, 3580 m, 25.viii.1998, R. Aimituma. Paratypes: Santuario Nacional Ampay, Bosque Nativo del Ampay [13 ° 359410 S 72 ° 529480W], 3100–3300 m, 26.viii.1998, J.C. Chaparro and J.A. Ochoa, 2 ♀ (MHNC), 1 ♀ (CDA 088), 1 ♀ (MACN-Ar 10039); Santuario Nacional Ampay, Ccorhuani [ca. 13 ° 359S 72 ° 529W], 3280 m, 18.ix.1998, R. Aimituma, 1 ♀ (MUSM).

NEW RECORDS: PERU: Apurímac Department: Abancay Province: Santuario Nacional Ampay, Bosque Nativo del Ampay, 13 ° 359S 72 ° 529W, 3200 m, 17.vii.2000, J.A. Ochoa, in Podocarpus glomeratus forest, 1 ♀ (AMNH [LP 1918]).

DIAGNOSIS: Orobothriurus ampay differs from all other species in the genus by its well- developed pigmentation pattern. The tergites of this species are entirely, densely pigmented (fig. 12D) and the paired VL stripes contiguous with the VM stripe posteriorly on metasomal segments I–V (fig. 11A) whereas, in other species, tergites I–VI each possess two lateral spots delimiting an unpigmented median stripe along the mesosoma (fig. 13E– G) and the paired VL stripes of the metasomal segments are not contiguous with the VM stripe posteriorly, at least on segments IV and V (figs. 11B–D, 13A, D). Orobothriurus ampay may be further distinguished on the basis of metasomal carination, trichobothriotaxy and pedipalp chela ornamentation. The VSM carinae, present on metasomal segment IV in O. ampay (fig. 17B), are absent in other species of Orobothriurus (fig. 17A). The angle formed between pedipalp chela trichobothria eb–Et 5 – Et 4 is less than 90 ° in O. ampay (fig. 25A), but greater than 90 ° in other species (figs. 25B, D, 26B, C). The acuminate conical apophysis on the internal surface of the male pedipalp chela manus, observed in all other Orobothriurus species (except O. wawita , in which it is absent altogether), is reduced to a few granules in O. ampay . The hemispermatophore of O. ampay resembles that of O. parvus and O. wawita in possessing an elongated apex and a short frontal crest, which is less than half the length of the lamina. However, the ventral margin of the apex is inclined to the dorsal surface and curved distally in O. ampay (fig. 27A) and O. parvus (fig. 27B), but straight in O wawita (fig. 27C). Finally, O. ampay possesses the lowest pectinal tooth count in the genus (12–15).

DISTRIBUTION: Orobothriurus ampay is known only from the Santuario Nacional Ampay, near Abancay in the Apurímac Department of southeastern Peru, at 3100– 3580 m (figs. 3E, 52).

ECOLOGY: Orobothriurus ampay appears to be endemic to an inter-Andean forest of Podocarpus glomeratus Don (Podocarpaceae) (fig. 3E). All known records of this species were collected inside the forest under stones on moist soil. No other scorpion species are known from this forest. The closest records are two other bothriurids, Brachistosternus peruvianus Piza, 1974 , and Pachakutej iskay ( Acosta and Ochoa, 2001) , and a buthid, Tityus footei Chamberlin, 1916 , which inhabit an adjacent dry valley in Tamburco.
