Comments.
In their revision of Phoneutria Simó and Brescovit (2001) distinguished the Amazonian specimens of Phoneutria boliviensis from the specimens from Colombia and Central America (which we identify now as P. depilata ) based on the epigynal morphology: "In specimens from Central America to Colombia it is triangular, with a wide base and a narrow apex, but in specimens from Ecuador to Bolivia the apex is more rounded". Based on the fact that Simó & Brescovit were able to distinguish these epigynal morphological differences among these two Phoneutria species and that the only species of Phoneutria in the trans-Andean region is P. depilata , we suggest that Ctenus peregrinoides (from Guatemala) is a junior synonym of P. depilata . Strand described Ctenus signativenter in 1909 based on immature syntypes from Paramba, Ecuador (one male and two female syntypes, all immatures, 3500 ft, 28 April 1898, Rosenberg leg., in ZMB 306 View Materials , not examined). We have designated Ctenus signativenter as a nomen dubium because the exact identity of this species cannot be ascertained with immature specimens, but we note that the type locality suggests that the C. signativenter syntypes belong to P. depilata . Based on the epigynal morphology ( Schmidt 1956, fig.3), we synonymize Phoneutria colombiana with P. depilata . Both Ctenus peregrinoides and Phoneutria colombiana had been synonymized with P. boliviensis by Simó and Brescovit (2001) .

Diagnosis.
Males of P. depilata resemble those of P. boliviensis by the truncated apex of the RTA (Fig. 9C, D View Figure 9 ), but differ from this and the remaining Phoneutria species by the lateral pronounced projection of the locking lobes visible in ventral view (Fig. 9B View Figure 9 ). In addition, males present an embolus with an internal bulge which is absent in P. boliviensis ; and a much larger tegulum (Figs 7B View Figure 7 , 9B View Figure 9 ). Females of P. boliviensis also resemble those of P. depilata by the general configuration of the epigynum but differ by the narrow area of the EMF (Fig. 8A View Figure 8 ), copulatory ducts slightly sclerotized (Fig. 8A View Figure 8 ), and large spermatheca heads (Figs 8B View Figure 8 , 10D View Figure 10 ). In addition, both males and females of P. depilata can be distinguished from P. boliviensis and the remaining Amazonian species ( P. perty and P. fera ) by the four conspicuous series of yellow dots in the ventral side of the abdomen (this character is also present in Phoneutria eickstedtae Martins & Bertani, 2007).

Natural history.
This species is found in disturbed habitats associated with both dry and humid tropical forests (0-1700 m), usually on the ground with sparse litter and low vegetation ( Hazzi 2014). The range of eggs per egg sac is 430-1300, and spiderlings emerge 28-34 days after the egg sacs are produced. Sexual maturity occurs after 14-17 molts, and spiders mature 300-465 days after emerging from the egg sac ( Hazzi 2014). Valenzuela-Rojas et al. (2020) reported that P. depilata is an euryphagous predator with a broad diet made up predominantly of arthropods and to a lesser extent of small vertebrates ( Gekkonidae , Hylidae , and Sphaerodactylidae ). There are human bite records of this species reported in Costa Rica and in banana plantations in Colombia ( Florez et al. 2003). All the cases reported have occurred with adults, and most of them have presented mild to moderate envenomation symptoms, with only one patient presenting severe symptoms such as renal failure ( Florez et al. 2003). Estrada-Gomez et al. (2015) partially characterized the venom of this species, detecting Ctenitoxin-Pb48 and Ctenitoxin-Pb53, which showed a high homology with other Ctenitoxins (family Tx3) from P. nigriventer , P. keyserlingi and P. reidyi affecting voltage-gated calcium receptors (Cav 1, 2.1, 2.2 and 2.3) and NMDA-glutamate receptors. Valenzuela-Rojas et al. (2019) found that the venom of P. depilata was significantly more effective on vertebrate (geckos) than invertebrate (spiders) prey in both LD50 and immobilization time. In addition, males had slightly more toxic venom (LD50) to geckos and much more toxic venom to spiders when compared to females ( Valenzuela-Rojas et al. 2019). For two periods, March to May and October to November, adult males and females with egg sacs are always found in homes in the Inter-Andean Cauca Valley of Colombia. This likely indicates two reproductive peaks that coincided with the two rainy seasons during those same periods (N. Hazzi, unpub. data).
