Etymology. The epithet jeronimae   is a Latin noun in the genitive case created by adding the singular Latin genitive case suffix -e to the first name of a female person. The specific epithet is named after Jerônima Mesquita (1880–1972), a Brazilian feminist, pioneer of the women’s suffrage in Brazil. She also advocated for the equality of rights and opportunity of women, and co-founder, along with Berta Lutz (1894–1976) and Stella Guerra Duval (1879–1971), of the League for the Intellectual Emancipation of Women in 1918 (which was subsequently named Brazilian Federation for Women’s Progress).

Comments. Hylomyrma jeronimae   is similar to H. blandiens   , H. dentiloba   and H. macielae   . Hylomyrma jeronimae   and H. dentiloba   are restricted to Central America ( Figs. 84 View FIGURE 84 , 86 View FIGURE 86 ), co-occuring in Barro Colorado Island, Panama, whereas H. blandiens   has a broad distribution in northwestern South America, from Bolivia to French Guiana ( Fig. 84 View FIGURE 84 ), overlapping in part with the area of distribution of H. macielae   (south Colombia and the center-north of Ecuador) ( Fig. 86 View FIGURE 86 ). Hylomyrma jeronimae   can be distinguished from H. blandiens   and H. dentiloba   (characteristic of both in parentheses) by the regular to irregular, and divergent striae on the mesial region of head dorsum (vs. regular striae in part directed to posterior margin and in part anteriorly divergent and posteriorly convergent), the reniform eye (vs. drop-shaped), the striation on the mesosoml dorsum assuming multiple directions (vs. longitudinal striation), the continuous dorsal margin of petiole (vs. discontinuous), and the striae on tergum of the first gastral segment restrict to its basal region (vs. extending up to its first third). Hylomyrma jeronimae   and H. macielae   share the adjacent striae on the mesosoma, but the former differs from the latter in the reniform eye (vs. oval), and the continuous dorsal margin of petiole (vs. discontinuous).

After observing the images of H. cf. dentiloba   sp.1 (CASENT0636001) from Costa Rica ( Pierce et al. 2017), we understand that this species is Hylomyrma jeronimae   n. sp. The authors stated that H. dentiloba   and H. versuta   are morphologically identical, being differentiated only in their geographical distribution. However, H. jeronimae   (the H. cf. dentiloba   sp.1) can be distinguished from H. versuta   in the striation on the mesosomal dorsum assuming multiple directions (vs. logitudinal striation), the striae interspaces on the mesosoma indistinguishable (vs. distinguishable), and the continuous dorsal margin of petiole (vs. discontinuous). Also, we indicate five morphological differences between H. jeronimae   and the true H. dentiloba   (the H. cf. dentiloba   sp.2) in the previous paragraph.

Distribution. This species occurs in Costa Rica and Panama ( Fig. 84 View FIGURE 84 ).

Natural history. Hylomyrma jeronimae   inhabits forested areas at elevations ranging from 180 to 950 m. Most known specimens were collected in the leaf-litter, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers.

MALE Unknown.

Etymology. The epithet lispectorae   is a Latin noun in the genitive case created by adding the singular Latin genitive case suffix -ae to the last name of a female person. The specific epithet is named after Clarice Lispector (1920–1977), born Chaya Pinkhasovna Lispector, a Ukrainian-Brazilian novelist, poetess, and short story writer— “ Liberdade é pouco. O que eu desejo ainda não tem nome ”.

Comments. This species is easily distinguished from most of its congeners, but it is very similar to H. montana   regarding the shape of mesosoma, and the sculpture and shape of the procoxa, petiole, postpetiole, and gaster. Also, the two species are sympatric, co-occuring in two Ecuadorian localities: Centro Científico Río Palenque, and 4 km E of Santo Domingo de los Colorados ( Figs. 83 View FIGURE 83 , 84 View FIGURE 84 ). Hylomyrma lispectorae   can be distinguished from H. montana   (characteristic in parentheses) in the dorsum of head and mesosoma by the vermicular striae of variable thickness with indistinguishable interspaces (vs. irregular striae of uniform thickness with distinguishable interspaces), and the notably convex dorsal margin of mesosoma (vs. somewhat straight).

Distribution. Hylomyrma lispectorae   is known from Colombia and Ecuador ( Fig. 84 View FIGURE 84 ).

Natural history. This species occurs in tropical rainforest areas at altitudes below 600 m. Specimens were collected in leaf-litter with winkler extractors and Berlese-Tüllgren funnels, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers.

Longitudinal, regular to irregular striae on scutum going from an anterior central point towards transcutal suture, interspaces indistinguishable. Longitudinal, regular to irregular striae on anepisternum and katepisternum, some vermicular striae on katepisternum, thinner striae between thicker striae. Axilla and scutellum with same sculpture of scutum. Scutoscutellar sulcus inconspicuous. Transverse striae on propodeum (DV). Lateral surface of mesosoma with vermicular striae directed to propodeal spine. Wings as in Fig. 81E. View FIGURE 81

MALE Unknown.

Etymology. The epithet lispectorae   is a Latin noun in the genitive case created by adding the singular Latin genitive case suffix -ae to the last name of a female person. The specific epithet is named after Clarice Lispector (1920–1977), born Chaya Pinkhasovna Lispector, a Ukrainian-Brazilian novelist, poetess, and short story writer— “ Liberdade é pouco. O que eu desejo ainda não tem nome ”.

Comments. This species is easily distinguished from most of its congeners, but it is very similar to H. montana   regarding the shape of mesosoma, and the sculpture and shape of the procoxa, petiole, postpetiole, and gaster. Also, the two species are sympatric, co-occuring in two Ecuadorian localities: Centro Científico Río Palenque, and 4 km E of Santo Domingo de los Colorados ( Figs. 83 View FIGURE 83 , 84 View FIGURE 84 ). Hylomyrma lispectorae   can be distinguished from H. montana   (characteristic in parentheses) in the dorsum of head and mesosoma by the vermicular striae of variable thickness with indistinguishable interspaces (vs. irregular striae of uniform thickness with distinguishable interspaces), and the notably convex dorsal margin of mesosoma (vs. somewhat straight).

Distribution. Hylomyrma lispectorae   is known from Colombia and Ecuador ( Fig. 84 View FIGURE 84 ).

Natural history. This species occurs in tropical rainforest areas at altitudes below 600 m. Specimens were collected in leaf-litter with winkler extractors and Berlese-Tüllgren funnels, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers.
