Paratypes: 2, same data as holotype but 13 IV 2004 (no. 340); 1, ditto, 17 IV 2004 (no. 341); 3, ditto, 12 V 2004 (no. 368); 3, ditto, 19 V 2004 (no. 428); 1, ditto, 20 X 2004 (no. 555); 1, ditto, 25 X 2004 (no. 583); 2, ditto, 25 IV 2005 (no. 711). See, Table 1 View TABLE 1 for detailed collecting data.

Symbiotic host. Morphotypes L1 and L2 of Aenictus laeviceps .

Distribution. Malaysia (Borneo).

Etymology. In reference to the close resemblance to Aenictocleptis hirsutus .

Description. Body ( Fig. 32 View FIGURES 32 – 37 ) slender. Brown, except for mouth parts, legs, abdominal segments III–V and basal half of abdominal segment VI reddish brown. Head ( Fig. 32, 33 View FIGURES 32 – 37 ) with temple not developed. Mandibles strongly asymmetric; right mandible thick, outer margin around apical 1/4 convex. Antennae ( Figs. 32, 34 View FIGURES 32 – 37 ) slender, long, reaching just before posterior margins of elytra; segment XI slightly longer than IX and X combined: relative lengths of segments IX–XI: 14, 19, 35. Pronotum ( Figs. 32, 34 View FIGURES 32 – 37 ) as long as wide (width/length=1.01–1.03), densely covered with stout setae. Elytra ( Figs. 32, 33 View FIGURES 32 – 37 ) densely covered with stout setae. Abdominal segments VIII–IX densely covered with short setae; macrosetae on tergite VIII ( Fig. 38 View FIGURES 38 – 42 ) readily distinguished from other setae by thickness and color. Male: median lobe of aedeagus ( Figs. 39, 40 View FIGURES 38 – 42 ) with apical lobe elongate, gently narrowed apically, acutely pointed at apex; apical lobe of paramere ( Fig. 41 View FIGURES 38 – 42 ) parallel-sided, rounded at apex. Female: spermatheca ( Fig. 42 View FIGURES 38 – 42 ) with basal part spherically bulbous at base, without lateral projection.

Measurements. BL, ≈ 5.0–6.1; FBL, ≈ 2.4–2.6; HW, 0.99–1.06; EL, 0.46–0.50; AL, ≈ 2.2–2.4; PL, 0.88–1.02; PW, 0.93–1.05; ELW, ≈ 1.3–1.4; HTL, 1.31–1.38. N=5.

Diagnosis. This species is most similar to Aenictocleptis hirsutus in color, shape of mandibles, pronotal proportions, and density of setae on pronotum and elytra, but may be easily distinguished by the shorter setae on the abdominal segments VIII–IX, the shorter apical lobe of the aedeagal median lobe, and the absence of lateral projection in the basal part of the spermatheca.
