Diagnosis. Males and females of Aenigmarachne resemble those of Aphonopelma Pocock, 1901 ; Clavopelma Chamberlin, 1940 ; Cubanana Ortíz, 2008 ; Cyclosternum Ausserer, 1871 ; Cyrtopholis Simon, 1892 ; Nesipelma Schmidt & Kovarik, 1996 ; Reversopelma Schmidt, 2001 and Stichoplastoris Rudloff, 1997 in the general morphology of the bulb (palpal bulb with embolus narrower and acuminate) and the spermathecae (twin spermathecae with wide basis, narrow neck, and subspherical fundus), but differ from these and other genera of Theraphosini by the combination of the following characteristics: males with a palpal bulb with an elongated embolus that tapers towards the apex, longer in proportion to the combined length of the tegulum and subtegulum. The PS, PI and A keels are very poorly developed, only visible at the apex or along the apical third of the embolus ( Figs 2–4 View FIGURE 2 View FIGURE 3 View FIGURE 4 ). Absence of tibial apophyses on leg I and presence of a retrolateral palpal nodule ( Fig. 5 View FIGURE 5 ). Males and females with the retrolateral face of femora IV lacking a pad of plumose setae. The trochanters of all legs and femur IV lack a stridulatory organ. Presence of type I setae, subtype I b in males and subtype I e in females and juveniles.
