Symbiotic host. Morphotype L1 of Aenictus laeviceps .
Distribution. Malaysia (Borneo).
Etymology. Dedicated to Dr. T. Matsumoto, the second author of this paper and collector of the type series.
Description. Almost uniformly reddish brown. Head ( Figs. 48–51 View FIGURES 48 – 56 ) with dorsal surface completely glabrous except for several setae in front of eyes. Pronotum ( Fig. 52 View FIGURES 48 – 56 ) with ratio length/width=1.24–1.25, with 7 or 8 setae along midline, 1 seta antero-laterally and 1 seta postero-laterally. Elytra with 6–10 minute setae. Abdomen ( Figs. 53–55 View FIGURES 48 – 56 ) with numbers of macrosetae from tergite II–VIII: 1, 1, 1, 6, 6, 6; gland openings on sternites III–V clear. Male: median lobe of aedeagus ( Figs. 57, 58 View FIGURES 57 – 62 ) gently narrowed apically in lateral view, with lateral ridge which is gradually narrowed from middle to apex in parameral view. Female: spermatheca ( Fig. 59 View FIGURES 57 – 62 ) with basal part lacking basal projection; apical lobe with lateral ridge small.
Measurements. BL, ≈ 3.5–3.8; FBL, ≈ 1.7–1.9; HW, 0.53–0.56; EL, 0.254–0.263; AL, ≈ 1.7–1.8; PL, 0.56– 0.58; PW, 0.45–0.46; ELW, 0.67–0.69; HTL, 1.10–1.21. N=5.
Diagnosis. This species is most similar to Mimaenictus wilsoni (M. w.) in the presence of lateral ridge in median lobe of aedeagus, but is clearly distinguished from it by the shorter setae on the pronotum (in M. w., the setae are longer and denser in the anterior area and lap over each other) and the sparser setae on the elytra (M. w. has more than 15 setae). The shape of the median lobe of aedeagus and that of the spermatheca are also different. In M. w. the apical lobe of the median lobe of aedeagus ( Figs. 60, 61 View FIGURES 57 – 62 ) is slightly constricted near the base and almost parallel-sided in lateral view, and the lateral ridge is almost semi-circular in parameral view; the basal part of spermatheca ( Fig. 62 View FIGURES 57 – 62 ) is with a basal projection, and the apical lobe is with a large lateral ridge.
