Types. Male holotype labeled “Buru” and “ Holotype Xylotrupes clinias buru Rowland 2011 ” and eight male paratypes from Buru Island, Indonesia deposited at ZMHB.

Etymology. The name buru is a noun used in apposition and refers to Buru Island, Indonesia, the only know locality of this taxon.

Description. Measures of male holotype and paratypes in mm (range of 8 paratypes): Total length 69 (47-60), body length 44 (37-42), cephalic horn length 20.7 (10.1-19.6), pronotal horn length 36.8 (16.7- 34.1), pronotal width 20.1 (17.2-18.8), elytral length 30.0 (26.3-28.1), elytral width 27.0 (22.6-24.8), abdominal height 16.0 (13.5-14.6). Head: Cephalic horn denticle absent; mandible with two denticles. Thorax: Pronotal horn expression dimorphic; pronotal carinae strong in males, in lateral view they extend beyond anterior midline of pronotum; pronotal punctation light in large males; male elytra glossy, sculpturing almost absent. Genitalia: Parameres essentially symmetric; paramere blades angled toward orifice; right raspular spine gradually curved, basal process distinct; left raspular spine longer and wider than right raspular spine; left raspular base small, oval; basal raspular piece shorter than right raspula. Color: Males dark reddish brown, slightly bicolored.

Comparisons. The raspulae of X. clinias buru are distinct from other Xylotrupes in that the left raspular spine is larger or as large as the right raspular spine. Specifically in regard to the other known populations of X. clinias , X. clinias buru is distinct in having a larger right raspular basal process and an oval rather than triangular left raspular base. Xylotrupes clinias buru shares the latter character state with most specimens of X. ulysses , though in the latter taxon occasional specimens have a triangular left raspular base.

Distribution. Buru Island, Indonesia.
