Notes

In the original description of the species ( Cavallo and Ferretti 2015), the ventral crest of the prolateral inferior keel was described as a subapical keel due to its triangular shape and position. However, a more detailed examination of the male holotype and the comparison with the other species of Hapalotremus led us to identify a continuous PI very well-developed along the embolus having a ventral expansion or crest, as found in all known species.

Amended diagnosis

Hapalotremus martinorum is characterized by a distinct green pubescence between the patella and tarsi of legs and on the lateral faces of the abdomen in combination with red setae on the urticating patch ( Figure 1c, d View Figure 1 ). Males of H. martinorum can be distinguished from those of H. albipes and H. major by a large number of labial cuspules (more than 20), tibia I about 10% longer than metatarsus I ( Figure 13g View Figure 13 ), by having a slightly developed retrolateral rounded process on palpal tibia ( Figure 13h, i View Figure 13 ), unequal sizes of tibial apophysis branches ( PB smaller than RB) ( Figure 13f, g View Figure 13 ) and slower curvature of metatarsus I ( Figure 13g View Figure 13 ). Palpal bulb resembles that of H. major , but it differs by the more developed digitiform apophysis ( Figure 14a–d View Figure 14 ) and prolateral keels ( Figure 14a–d View Figure 14 ). Females of H. martinorum can be distinguished from those of H. albipes and H. major by the larger number of cuspules on labium (more than 25 cuspules) ( Figures 15b View Figure 15 , 16a View Figure 16 ). Additionally, males of H. martinorum differ from all Hapalotremus species by the presence of an accessory keel ( AK) on palpal embolus located among PI and A ( Figure 14a, e View Figure 14 ). Also, females of H. martinorum can be characterized by the shape of the spermathecae, with basal portion wider than apical, apical lateral projections slightly developed and protrude from the apical median region ( Figure 16e View Figure 16 ).

Distribution and habitat

Known from Salta Province, northwestern Argentina ( Figure 36 View Figure 36 ). Specimens were found in high-cloud forests of the Yungas region ( Figure 3a View Figure 3 ). These spiders occupy short burrows or crevices under stones and usually the stones, where individuals can be found, are covered with mosses and small ferns (see more details of natural history in Cavallo and Ferretti 2015).
