Male Morphology

Measurements
These measurements were used by Ramamonjisoa et al. (2023) when describing males of the myrmicine species Erromyrma latinodis.

Definitions

 * EL
 * Maximum eye length measured in full-face view along its maximum vertical diameter.


 * F1
 * Maximum length of the pedicel (1st funicular segment, 2nd antennal segment) measured in a straight line.


 * HL
 * Maximum head length in full-face view, measured in a straight line, from the anterior clypeal margin to the midpoint of a straight line drawn across the occipital margin.


 * HW1
 * Head width at the level of the posterior margin of compound eyes, measured in full-face view.


 * HW2
 * Maximum head width including the compound eyes, measured in full-face view.


 * IOD
 * Inner ocellar distance. Minimum distance between the inner edges of the two lateral ocelli, measured in full-face view.


 * LOD
 * Lateral ocellar distance. Minimum distance between the inner edge of the median and lateral ocelli, measured in full-face view.


 * OOD
 * Ocular-ocellar distance. Minimum distance from the outer edge of a lateral ocellus to the compound eyes, measured in full-face view.


 * PL
 * Petiole length, measured in profile view from the anterior margin of the peduncle to posterior most point of the petiolar tergite.


 * PW
 * Petiolar width. Maximum petiole width, measured in dorsal view.


 * PPW
 * Postpetiolar width. Maximum postpetiole width, measured in dorsal view.


 * SL
 * Scape length. Maximum length of the antennal scape measured in a straight line, excluding the basal constriction and condylar bulb.

Indices

 * CI
 * Cephalic index. HW1/HL × 100.


 * SI
 * Scape index. SL/HW1 × 100.


 * EI
 * Eye index. EL/HW1 × 100.


 * PI
 * Petiolar index. PL/PPL.
 * Petiolar index. PL/PPL.

 * radius


 * Rs, rs
 * radial sector

Genitalia
Male genitalia in ants has been reviewed by Boudinot (2013).

Ward & Boudinot (2021) provide the following genitalic term equivalencies among key works (see also Boudinot (2013) and references within cited studies):
 * Cupula (= basal ring of Snodgrass (1941, 1957))
 * Cuspis (= cuspis or distivolsella)
 * Gonocoxa (= gonocoxite in the strict sense, basimere of Snodgrass (1957), gonostipes of Schulmeister (2001))
 * Gonopod (= gonopodites in the strict sense, parameres of Snodgrass (1941, 1957), latimeres of Schulmeister (2001), stipites of Kempf (1956), stipes of Birket-Smith (1981))
 * Gonapophysis (= digitus of Snodgrass (1941, 1957); Schulmeister (2001))
 * Gonostylus (= telomere or harpago of Snodgrass (1957), harpe of Schulmeister (2001))
 * Penial sclerite (= aedeagal sclerite of Snodgrass (1941, 1957), sagitta of Snodgrass (1957), penisvalva of Schulmeister (2001))
