Materials Examined
Material examined.ECUADOR, Pichincha: Pedro Vicente (road to Quito from Puerto Quito), 79 °07’W, 00º05’S, ♂, 09– 12.VII. 1988, W. Maddison (MCZ). Note. Male and female were considered conspecific for having the same color pattern.
Diagnosis
Diagnosis. The males of Alpaida cisneros resemble those of A. anchicaya (see Levi 1988, figure 591) in the color pattern (Fig. 6) and in the embolus position, which is perpendicular to the cymbium. Alpaida cisneros can be distinguished from A. anchicaya by the conductor shape, by the short median apophysis, which barely surpasses the tegulum (Fig. 5), and by the wide embolus (not filiform as in A. anchicaya) (see Levi 1988, figure 592)
