Diagnosis: Males of this species can be differentiated from others of the genus except L. fritzi by the combination of two submarginal cells, pronotal lobe black, metatibial spurs straight, S7 apical lobe with dense apicomedially oriented hairs ( Fig. 72 ). Males can be differentiated from L. fritzi by mesosoma moderately imbricate, somewhat shiny (as in Fig. 78 ) as opposed to strongly imbricate and dull in L. fritzi and the degree of ventral recurvature of the clypeal apex, which forms an angle that is at most a right angle in L. cochabambensis ( Figs. 70 & 153 ) but clearly more than a right angle in L. fritzi ( Figs. 81 & 151 ). Females of this species can be differentiated from all others except L. amblayensis by the combination of two submarginal cells, pronotal lobe black, metatibial spurs straight and facial fovea more than 5.5 X as long as wide. Females can be differentiated from L. amblayensis by mesoscutum and scutellum almost devoid of microsculpture, shiny ( Fig. 78 ) as opposed to both with distinct but weak imbrication, somewhat shiny, in L. amblayensis ( Fig. 206 ).

Material studied. Holotype male, allotype female and one paratype male. Holotype and allotype as follows: BOLIVIA, Cochabamba: Pena Colorada , 1800 m, 21.ii.1976, L. E. Pena. Both specimens are at the AMNH . Paratype male: BOLIVIA, Cochabamba: Rio Mizque , 2100m., Sept. 2, 1976, L.E. Peña .

Etymology. The species is named after the type locality.

Comments. Like the previous species, when treated as having three submarginal cells, males of L. cochabambensis also fail at couplet 10 which contrasts different forms of process on S2 and this species has no such process. The female fails at couplet 33 as it is not smooth and shiny above the antennal sockets (required to go to couplet 34) and lacks a yellow marking on the pronotal lobe (required to go to couplet 35).

This species belongs to the same species group as the one previous and the two following.
