The scutatus Group

Males of this group lack a retroventral projection on the palpal bulb, but have a well-developed embolar base from which the embolus originates at a right angle (figs. 234, 319). Females resemble those of the cotopaxi group in having the postepigastric scutum so short that it does not fully reach the posterior spiracles and the groove connecting them, but the epigastric scutum has a much less modified posterior margin (figs. 309, 333). The group appears to be restricted to the eastern slopes of the Ecuadorean Andes.
