Key to the Indian Myrmecina species

This key to the Indian species of Myrmecina (based on the worker caste) is provided by Sheela et al. (2020). Note that Myrmecina pilicornis, which is onky known from a single, unassociated male, is not included in this key.

1

• Thorax transversely striate => 2
• Thorax longitudinally striate => 3

2

• Propodeal spines thin, long and curved outwards; dorsal propodeal teeth well defined; in dorsal view, anterior margin of gaster concave with sides sharply defined => Myrmecina urbanii

• Propodeal spines more or less straight, dorsal propodeal teeth not distinct, in dorsal view anterior margin of gaster transverse with sides not produced in front => Myrmecina vidyae

3

• Clypeal teeth distinct => Myrmecina striata

• Clypeal teeth weak or absent => 4

4

• Dorsal propodeal teeth, anterior to the propodeal spines, minute; postpetiole with prominent lateral keels; gaster punctuate => Myrmecina camellia

• Dorsal propodeal teeth, anterior to the propodeal spines, large and prominent (the teeth are dorsal to the propodeal spines); lateral keels on post petiole not well developed; gaster smooth and shining => Myrmecina narendra
