Type material examined. Holotype ♀ ( MNHN), labelled ( Fig. 24): “Iles / Malaises [hw, yellow label] // TYPE [p, red characters] // MUSEUM PARIS / Coll. A. Grouvelle 1915 [p] // HOLOTYPE / Eusilpha (Calosilpha) / renatae Portevin, 1920 / (label added by / Jan Růžička, 2009) [p, red label] // Necrophila (Chrysosilpha) / renatae / (Portevin, 1920) [p] ♀ [hw] / Jan Růžička det. 200 [p] 8 [hw]”.

Additional material examined. See Appendix 1.

Diagnostic description. Body length 16.0–18.5 mm (17.0 mm in the holotype), maximum body width 8.0–9.5 mm (9.0 mm in the holotype). Head with metallic blue gular region. Anterior emargination of labrum wide, shallow (as on Fig. 31). Pronotum metallic dark blue, only anterolateral portion orange ( Figs. 3–4). Proventrite metallic blue or green ( Fig. 34). Elytra metallic blue or green ( Figs. 3–4).

Male. Apex of elytron obliquely truncate, with distinct apical denticle ( Fig. 3). Genital segment with wider ventrite 9; spiculum gastrale slender, distinctly shorter than ventrite 9 ( Fig. 12). Length of aedeagus 2.8 mm, median lobe slender, with apex narrowed to a slender tip ( Fig. 11). Parameres slender ( Fig. 11). Basal portion of aedeagus slender ( Fig. 11).

Female. Apex of elytron wide, elongate, distinctly sinuate in posteroapical part, with distinct apical denticle ( Fig. 4), only rarely is denticle only very minute. Tergum 10 transverse, with posterior margin narrow ( Fig. 13). Tergum 9 wide and subquadrate in ventral view ( Fig. 14). Stylus distinctly longer than apex of coxite ( Fig. 14).

Ecology. Scarce locality data indicate necrophagous association with dead rat and traps baited with decaying fish and excrements, and also attraction to light trap. Specimen data indicate that adults are active all year round (with no vouchers only from February and July), with most specimens collected in January, April and December ( Table 3). The species has been collected at altitudes between 200–1700 m.
