Diagnosis. Apical scutellar macrosetae absent; abdomen shining black, apruinose; R 4+5 bifurcation usually posterior or at the level of apex of cell d; epandrium rounded apically; gonocoxite with apex blunt; spermathecae rounded.
Description of male holotype. Lengths. Body: 13.2 mm; wing: 11 mm.
The description of Glaphyropyga monticola sp. nov. is similar to that of G. andina sp. nov. except for the following: Head. (Figs 21–22) face golden cinereous pruinose, some sparse grey pruinosity on facial gibbosity; seta-like sensorial element of stylus also preapical and placed dorsally, but about a third the length of second element of stylus and only extending at level of its apex (Fig. 23a); mystacal macrosetae mostly yellow, except some lateral ones, black. Wing. R 4+5 bifurcation posterior to level of apex of cell d; crossvein r–m about the middle of cell d. Legs. Predominantly yellow, only brown suffusion is present dorsally on mid and hind femora, but not completely defined as a stripe; fore tibia with three ventral macrosetae. Abdomen. Black, apruinose. Terminalia. (Figs 24–27) Epandrium very thin, curved downwards before middle; gonocoxite with apex broad and blunt (Fig. 28); phallus not medially expanded in dorsal view; ejaculatory apodeme inserted posterior to middle of phallus (Figs 29–30).
Female. (Fig. 31). Similar to male, except by the following: Seta-like sensorial element of stylus placed apically, minute and hard to distinguish (Fig. 23b). Terminalia (Fig. 32); segment eight short, half the length of the former one; arms of genital fork slightly divergent, genital fork apodeme broad and rounded; common duct short; individual ducts four times as long as common duct; spermathecae rounded (Fig. 33).
Variation. In some specimens the R 4 +5 bifurcation is at the level of the apex of cell d, in one female and one male it is anterior to the apex.
Etymology. A Latin feminine noun in apposition, meaning a mountain dweller. This refers to the habitat of this species, Wayquecha, the type locality, is located in a montane cloud forest in the department of Cuzco.
Distribution. (Fig. 34). Kosñipata Valley, Paucartambo, Cuzco, Peru.

Holotype condition. Detached terminalia pinned along with specimen.
Remarks. These two new species have been collected in sympatry, and are very alike, but they can be differentiated using the diagnoses provided and additional features such as the leg coloration; in G. monticola sp. nov. the legs are predominantly yellow, and only brown suffusion is present dorsally on mid and hind femora, while in G. andina sp. nov. the mid and hind femora present a dark brown dorsal stripe and the hind tibiae and tarsi are brown. However, the more evident differences can be observed in the internal structures of the male and female genitalia, especially the female spermathecae, fusiform in G. andina sp. nov. and rounded in G. monticola sp. nov. On the other hand, both species share some features that stand out when compared with other previously described Glaphyropyga. The most outstanding is the lack of a well-developed pair of apical scutellar macrosetae (only setae are present), additionally, the face is not as narrow as in other examined Glaphyropyga that have it as narrow or narrower than a tenth the width of the head; the ocellar tubercles in the new species are less prominent and have sloping sides, while this structure is prominent and has vertical sides in other Glaphyropyga (Hull 1962). Moreover, both new species have the abdomen uniform in coloration, a feature shared at least with G. renatoi, G. tachirensis, and possibly with G. setosifemu r, but in species such as G. bolivari, G. himantocera and G. pollinifera the abdomen is yellow ventrally, at least in the proximal sternites, possessing a strong contrast between the dorsal and the ventral surfaces.
Finally, five specimens among the additional material examined present a long stylus, and they seem to belong to at least two different undescribed species, from Cuzco and Loreto. Unfortunately, the only two males are in bad condition and more specimens are needed for their future description. One species may correspond to the one recorded by Fisher (1985), as Glaphyropyga sp. 1 nr. Aristata, but the other one, a male collected in Loreto, is also certainly different from G. aristata, since it presents four apical scutellar macrosetae.
