Adetomyrma

description: Genus Adetomyrma
Adetomyrma Ward, 1994: 160.
Type-species: Adetomyrma venatrix, by original designation.
Adetomyrma in Ponerinae, Amblyoponini: Ward, 1994: 159.
Adetomyrma in Amblyoponinae, Amblyoponini: Bolton, 2003: 42, 153.
Diagnosis of worker
The diagnostic characters uniquely observed in Adetomyrma within the subfamily Amblyoponinae are given in italics.
1. Compound eye lacking.
2. Anterior margin of clypeus with specialized conical setae.
3. Mandible falcate without a distinct basal angle.
4. Teeth on inner margin of the mandible completely replaced by the basal denticles excluding apical two teeth.
5. Apical and subapical teeth developed.
6. No basal large projection present on basal portion of mandibular inner margin.
7. Constriction between petiole and abdominal segment III absent.
8. Constriction between pre- and post-sclerites on abdominal segment IV absent.
Diagnosis of male
The diagnostic characters uniquely observed in Adetomyrma within the subfamily Amblyoponinae are given in italics.
1. Frontal carinae absent.
2. Anterior margin of clypeus with specialized conical setae.
3. Antenna consisting of 13 segments.
4. Mandible with single, blunt apical tooth.
5. Palpal formula 3,3 / 2,3 / 2,2.
6. Notaulus distinct or absent.
7. Mesepimeron with or without distinct posterodorsal lobe (epimeral lobe).
8. Mesotibia with two spurs in most cases, rarely with single spur.
9. Metatibia with two spurs.
10. No constriction present between petiole and abdominal segment III in dorsal view.
11. Abdominal segment IV with or without tergosternal fusion.
12. Pretergite of abdominal segment IV not distinctly differentiated from posttergite, without transverse furrow between them.
13. Pygostyles present.
14. Distal margin of abdominal sternum IX concave.
15. Separation between basimere and harpago usually indistinct but distinct in some species.
16. Basal projection on cuspis well developed.
17. Basicoventral portion of the aedeagus in lateral view extended basally in most cases, shape of extension somewhat triangular to subtriangular, with relatively sharper distal apex.
18. Serrate denticles absent on basal portion of ventral margin of aedeagus in lateral view.
19. Pterostigma well-developed on forewing.
20. Radial sector on forewing wholly or partially absent between M+Rs and 2r-rs.
21. Radial sector on forewing fails to reach costal margin.
22. 2r-rs on forewing connected with radial sector posterior to pterostigma.
23. 2 rs-m absent on forewing.
24. cu-a on forewing located far from junction between media and cubitus.
25. Radius absent on hindwing in most cases but rarely weakly developed.
26. 1rs-m absent on hindwing.
27. Media on hindwing usually present apical to 1rs-m.
Generic diagnosis remarks
Generic diagnostic characters for the worker caste listed above build on those proposed in Ward (1994). Here we update some of those characters based on new material and new morphological data. The listed characters are consistently observed in all Adetomyrma workers, and distinguish Adetomyrma from the other Amblyoponine genera.
Male diagnostic characters follow those in Yoshimura & Fisher (2012).
For queens, all worker diagnostic characters are applicable except the developed compound eye and the presence of the constriction between petiole and AIII.
