Etymology. Blandus (Latin)   = smooth tongue, flattering, friendly.

Comments. Hylomyrma blandiens   , H. dentiloba   , and H. jeronimae   have similar morphology. Hylomyrma blandiens   was described based on two specimens (worker and queen), and H. dentiloba   based on one worker. Hylomyrma blandiens   has a broad distribution in northwestern South America, from Bolivia to French Guiana ( Fig. 84 View FIGURE 84 ), whereas H. dentiloba   and H. jeronimae   are restricted to Central America ( Figs. 84 View FIGURE 84 , 86 View FIGURE 86 ).

Hylomyrma blandiens   can be distinguished from H. dentiloba   (characteristic in parentheses) in the distinguishable interspaces on head dorsum striation (vs. indistinguishable interspaces), the convex dorsal margin of mesonotum (vs. straight), the propodeal spine slightly longer than the dorsal tooth of propodeal lobe (vs. shorter), and the striae length on the first gastral segment similar to the postpetiole length (vs. shorter than the postpetiole length). Hylomyrma blandiens   can be distinguished from H. jeronimae   in the regular striae on the mesial region of head dorsum in part directed to posterior margin and in part anteriorly divergent and posteriorly convergent (vs. regular to irregular striae and divergent), the drop-shaped eye (vs. reniform), the longitudinal striation on the mesosomal dorsum (vs. striae assuming multiple directions), the discontinuous dorsal margin of petiole (vs. continuous), and the striae on the tergum of the first gastral segment extending up to its first third (vs. restricted to its basal region). Also, H. blandiens   resembles H. macielae   in the regular divergent-convergent striae on the mesial region of head dorsum, and the indistinguishable interspaces on the mesosomal striation. Hylomyrma blandiens   can be distinguished from H. macielae   in the longitudinal striae on the mesosomal dorsum (striae assuming multiple directions in H. macielae   ). The western limit of the distribution of H. blandiens   , the east side of The Andes in Ecuador and Colombia ( Fig. 84 View FIGURE 84 ), overlaps in part with the distribution of H. macielae   ( Fig. 86 View FIGURE 86 ).

There is morphological variation across the range of H. blandiens   . Specimens from Ecuador have longer propodeal spines than elsewhere in the range. Specimens from Ecuador and Tachira, Venezuela, have a more pronounced mesoventral projection on the petiole. Striae on the mesial area of the head dorsum vary from being longitudinal to somewhat angled, divergent anteriorly and convergent posteriorly.

Distribution. This species is widespread in northwest South America ( Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela) and Trinidad ( Trinidad and Tobago) ( Fig. 84 View FIGURE 84 ).

Natural history. Hylomyrma blandiens   specimens are usually collected in samples of sifted leaf-litter in tropical rainforest. One Hylomyrma blandiens   nest with 24 specimens (3Q 21W) was collected by M.A. Ulysséa in a fallen twig on the ground in the Peruvian Amazon (Madre de Dios, Estación Biológica Villa Carmen). Apart from the specimens, plant remains and parts of a Curculionidae   imago were also found inside the nest, but there were no larvae or pupae.
