Material examined (n = 4): MEXICO: state of Mexico: Otzoloapan municipality: 3 km north-northeast of Zuluapan town : 19.1627°, −100.3085°: 1250 masl. ♂ a holotype ( CNAN-T0755 ), ♀ allotype ( CNAN-T0756 ) and ♀ paratype ( AMNH). 7/VIII/2012. D. Ortiz, C. Santibáñez, D. Barrales and R . Monjaraz, cols. Under stones. The holotype matured in captivity on 11/X/2012. ♀ paratype ( CNAN-T0757 ). 16/XII/2001. O. F. Francke and E. González, cols. Under a stone .

Diagnosis (emended): Morphology. Males differ from those of most Bonnetina species by having moderately developed tibiae I accessory apophysis, not geniculate pedipalpal bulbs, and long and sub-conical bulbal embolus, lacking PSA keel. They are unique by having the bulbal embolus remarkably slender and bearing a D keel. Females differ from most species by having pawn-shaped spermatheca. They differ from females of B. cyaneifemur by having the appendages covered by brownish pilosity, instead of copper to pink, and from those of B. minax in the much less dense and vivid carapace pubescence. Females of B. tenuiverpis also reach smaller size than those of B. cyaneifemur and B. minax . DNA. Diagnostic COI nucleotides (2): 159 (G), 324 (G). COI p -distances to other species (except B. minax ) above 8.5%; p -distance to B. minax between 2.4 and 2.9%. COI intra-specific distances less than 2% (Appendices S1, S5).

Species delimitation methods: Integrative ( Ortiz & Francke, 2016); this study: morphology and PTP.

Distribution and natural history: Bonnetina tenuiverpis is only known from the surroundings of Zuluapan, west of México State at 1250 masl, in the boundaries between the Trans-Mexican Volcanic Belt and the Balsas Basin ( Fig. 1; Table 1). The locality is grassland, where the spiders live under stones, with or without the protection of shallow retreats, syntopically with B. tanzeri and Brachypelma cf. albiceps . The single known male matured in captivity in October 2012 ( Ortiz & Francke, 2015).
