Key to Anochetus of India

This key to Indian workers of Anochetus is based on Bharti & Wachkoo (2013), with the addition of Anochetus daedalus by Abdus Shakur.

1

 * Pronotal disc (at least a broad central field) and all of first gastral tergum smooth and shining when clean, with at most fine, spaced punctures
 * Pronotal disc coarsely striate or punctate-rugulose; smooth interspaces, if any, narrow and usually coarsely punctate; first gastral tergum rugulose, striate or smooth, with or without coarse punctures

2

 * Inner mandibular margin bearing teeth which gradually reduce in size Anochetus daedalus
 * Inner mandibular margin smooth, without teeth

3

 * Modest or small sized, lightly pigmented species with reduced eyes: maximum measurable compound eye length < 0.15 mm, their greatest diameter < maximum width of a mandible
 * Large species with large eyes: maximum measurable eye length>0.25 mm and>maximum width of a mandible

4

 * Propodeal angles produced as a pair of short teeth
 * Propodeal angles unarmed Anochetus cryptus

5

 * Tiny species; HL+ML < 1.25 mm Anochetus pupulatus
 * Relatively larger species; HL+ML>1.55 mm Anochetus myops

6

 * Petiolar node axially compressed above; anterior slope concave, and summit rather bluntly rounded as seen from the side, but strongly transverse as seen from above; body with very numerous short, fine, erect hairs; appressed pubescence scarcely developed on head, mesosoma, petiole and gaster; with head in full face view, antennal scapes surpass posterior borders of occipital lobes by at least an apical scape width Anochetus rufus
 * Petiolar node thick, erect, barrel-shaped; anterior slope convex, summit broadly rounded in both directions and only slightly broader than long; body with few or no erect hairs, except on apex and underside of gaster (0–9 standing hairs on mesosoma and first gastral tergum), but with abundant and conspicuous appressed pubescence; with head is full-face view, antennal scapes do not reach, or at least do not distinctly surpass, posterior borders of occipital lobes Anochetus sedilloti

7

 * Petiolar node in profile thin, tapered to a very narrowly rounded, or even sharp, apical scale-like part near its base not more than 0.20 mm long
 * Petiolar node in profile thick, with broadly rounded summit, about as thick as near base of erect part of node

8

 * HL+ML < 1.50 mm; maximum measurable eye length < 0.15 mm Anochetus graeffei
 * HL+ML>1.50 mm; maximum measurable eye length>0.15 mm

9

 * Frons smooth and shining, the frontal striations extending only a short distance beyond the level of eyes; body yellowish; EL>0.25 Anochetus yerburyi
 * Frontal striation reaching all the way to nuchal carina, or most of the way; body red brown; EL < 0.25 Anochetus validus

10

 * First gastral tergum densely and more or less opaquely sculptured over at least the anterior half
 * First gastral tergum smooth and shinning, with only scattered, fine piligerous punctures Anochetus madaraszi

11

 * Anterodorsal margin of petiolar node slightly produced anteriad, overhanging the anterior slope, which tends to be concave; mesosoma red; first gastral tergum black or piceous, coarsely punctate-striate and opaque to near posterior border Anochetus kanariensis


 * Anterodorsal margin of petiolar node broadly rounded, like posterodorsal margin; anterior slope of node convex or straight as seen from the side; mesosoma, petiole and gaster piceous or blackish, often with bluish opalescence; the first gastral tergum with punctate-rugulose sculpture diminishing to nearly smooth and shinning on posterior half or third of the segment Anochetus obscurior
