Eocorythoderus incredibilis new species

( Figs. 1–7 View FIGURES 1 – 4 View FIGURES 5 – 7 )

Type series. Holotype, female, 1.0 km southwest of Angkor Wat, Angkor, Siem Reap, Cambodia, 5 VI 2012, M. Maruyama leg. ( KUM). Paratypes: 1 female, same data as holotype ( KUM); 6 females, 1.0 km south of Angkor Wat, Angkor, Siem Reap, Cambodia, 18 VIII 2012, M. Maruyama leg. ( CMN, KUM, NHM); 1 female, same data but 22 VIII 2012 ( KUM); 1 female, north of Preah Khan, Angkor, Siem Reap, Cambodia, 18 VIII 2012, M. Maruyama leg. ( KUM). In fungus gardens of Macrotermes gilvus .

Distribution. Northwestern Cambodia.

Etymology. The specific epithet means incredible, due to its extraordinary appearance and unexpected discovery in Cambodia.

Diagnosis. This species is readily distinguished from other Corythoderini by the genus diagnosis above, especially by the panduriform body shape and the stout, long mesolegs. Other corythoderine genera have more or less cyrindrical bodies and slender, short (shorter than metalegs) mesolegs.

Description. Head ( Figs. 1–3 View FIGURES 1 – 4 ) slightly narrower than pronotum; clypeus densely punctured along anterior margin; surface with sparse, long setae. Pronotum ( Figs. 1–3 View FIGURES 1 – 4 ) slightly shorter than elytra, with surface almost impunctate, sparsely with long setae. Elytra ( Figs. 1–3 View FIGURES 1 – 4 ) almost glabrous except for trichomes at apex of median projection. Proleg ( Fig. 4 View FIGURES 1 – 4 ) with tibia densely setiferous near apex with small recumbent setae. Mesoleg ( Fig. 4 View FIGURES 1 – 4 ) with trochanter with 3 or 4 setae; femur with about 10 setae on anterior margin, 8–10 setae around posterior margin; tibia moderately setiferous along lateral margins with long setae. Metaleg ( Fig. 4 View FIGURES 1 – 4 ) with setae of similar densities to mesoleg.

Measurements. In mm: Body length, 2.81–2.96; head width, 1.01–1.04; pronotal length, 1.03–1.08; pronotal width, 1.20–1.25; elytral width, 1.35–1.38; mesotibial length, 0.86–0.88.
