Phiale lehmanni Strand, 1908: 7 (description without illustrations of the male holotype from Popayan, Cauca, Colombia, [coordinates and altitude based on locality: 2.44°N, 76.61°W, 1750 m asl], collected by Friedrich Carl Lehmann, deposited in SMF 2377-141, photographs examined); Mello-Leitão, 1941: 299; Flórez & Sánchez, 1995: 363; World Spider Catalog, 2018.

Diagnosis. Placement in the nigrus species group of Pachomius is indicated by the presence of both a sclerotized (spike-like) lateral subterminal apophysis (LSA) and a well-developed proximal retrolateral lobe (pRL) of the male pedipalp. In this group, P. lehmanni can be distinguished from P. nigrus (Caporiacco, 1947) by its more slenderer LSA and embolus, narrower tegulum with a more slender pRL, and RTA with a wider base ( Figures 1-2 ; see Figures 6-9 in Ruiz et al., 2007).

Comments. The holotype male that was examined is well preserved and has a brown carapace with lateral and longitudinal stripes of white hairs, and eyes on black marks. The abdomen has an anterior and lateral white stripe, two transverse light-brown lines, and two lateral and posterior white spots ( Figure 3 ).

Distribution. The nigrus species group of Pachomius is comprised of two species from northern South America ( Figure 4 ). P. lehmanni is endemic to Colombia (Cauca), known from an elevation of approximately 1750 m above sea level. P. nigrus is known from Guyana (Potaro-Siparuni) and French Guiana (Saint-Élie) from an elevation between 150-270 m above sea level.
