propodeum
propodeum not angulate
propodeum not angulate
The propodeum is not angulate and lacks a distinct dorsal and posterior face. Used in Antkey to separate Camponotus variegatus, Camponotus atriceps, and Camponotus sexguttatus from Camponotus rectangularis.
propodeum with posterior protrusion and concave declivity
propodeum with posterior protrusion and concave declivity
The propodeum forms a posteriorly projecting protrusion (a) which causes the propodeal declivity (b) to be concave. Used in Antkey to separate species in the Ochetellus glaber complex from various species of dolichoderines and formicines.
propodeal declivity 2x dorsum
propodeal declivity 2x dorsum
The propodeal declivity is at least twice length of propodeal dorsum. Used in Antkey to separate Lasius from Anoplolepis and Formica.
propodeal declivity < 2x dorsum
propodeal declivity < 2x dorsum
The propodeal declivity is less than twice length of propodeal dorsum. Used in Antkey to separate Anoplolepis and Formica from Lasius.
propodeal spine length
propodeal spine length
propodeal spine length measured as a straight line from the center of the propodeal spiracle to the tip of the propodeal spine.
propodeal spines long
propodeal spines long
The propodeal spines are well developed, long and spinose. Used in Antkey to separate species of Tetramorium.
propodeal spines short
propodeal spines short
The propodeum spines are short, weakly developed and more closely resemble teeth or angles than long, well developed spines. Used in Antkey to separate species of Tetramorium.
propodeum unarmed
propodeum unarmed
The propodeum is entirely unarmed, completely lacking even small angles or teeth. Used in Antkey to separate Gnamptogenys porcata from Gnamptogenys triangularis.
propodeum with denticles
propodeum with denticles
The propodeum is armed with small teeth or denticles. Used in Antkey to separate Gnamptogenys triangularis from Gnamptogenys porcata.
propodeum and petiole armed
propodeum and petiole armed
The propodeum and petiolar node both armed with a pair of short teeth. Used in Antkey to separate Dolichoderus thoracicus from other species of Dolichoderinae and Formicinae.
