|Monomorium latinode, now Erromyrma latinodis|
(Species Checklist, Species by Country)
Recently discovered as part of a systematic study that revealed what had appeared to be an unusual Monomorium species was actually a distinctive representative of its own genus. As of 2019, the only descriptive information is what had previously been published for Monomorium latinode.
Bolton (1987) as given for description of the Monomorium latinode group (Monomorium species groups), which contained the lone species of this genus, E. latinodis: Worker. Size variable in any given series, showing simple monophasic allometric variation. Palp formula 3,3 (latinode). Mandibles unsculptured, with 5 teeth which decrease in size from apex to base. Median portion of clypeus broad and weakly bicarinate; posteriorly distinctly broader than the maximum width of either frontal lobe where it passes between them. Anterior clypeal margin without a pair of projecting teeth. Cephalic dorsum unsculptured except for hair-pits. Lateral portions of clypeus, area immediately behind clypeus, and area around antennal fossae mostly or entirely smooth, sometimes with vestiges of striolate or costulate sculpture. Eyes of moderate size, with 7-9 ommatidia in the longest row, their maximum diameter 0.19-0.21 x HW. Eyes situated conspicuously in front of the midlength of the sides in full-face view. In profile the long axis of the eye not strongly oblique with respect to the long axis of the head, the eyes not reniform. Antennae with 12 segments, with a strongly developed club of 3 segments. Propodeal spiracle circular. Propodeal dorsum transversely sculptured and rounding into the declivity. Track of metanotal groove in dorsal view not transverse but anteriorly arched or even inverted V-shaped medially. Petiolar spiracle close to level of anterior face of node. Fine standing hairs present on all dorsal surfaces of head and body.
Female. As worker but larger, the mesosoma with a full complement of flight sclerites and the head with ocelli present. HW slightly greater than maximum width of mesoscutum. With mesosoma in dorsal view the pronotum not forming part of the dorsum. Mesoscutum longer than broad. Axillary sclerites large and subtriangular in dorsal view, separated medially by a short impressed area between them. Parapsidal grooves faint. Forewing with cross-vein m-cu present.
