Note: The first author frequently collected / observed paler specimens that appear mature: head dark castaneous; pronotum anteriorly dark castaneous, rest dark yellow; elytron anterior half dark yellow, posterior half dark castaneous. Sculpture. Head moderately densely punctate, densest on frons; punctation on clypeus and vertex sparse; with indistinct microreticulation of small polygonal meshes. Punctures slightly larger than meshes. Pronotum with moderately dense punctation along fore-margin; rest sparsely punctate especially on disc; an indistinct microreticulation visible discally. Size of punctures as on head, discally distinctly smaller. Elytron with moderately dense and evenly distributed punctation; between punctures with hardly visible larger polygonal meshes. Ventral side with few punctures, shiny; only sternite 7 with distinct microreticulation. Structures. Metacoxal lines anteriorly diverge and do not reach posterior margin of metaventrite. Male. Elytron rather shiny, sometimes with antero-sutural microreticulation. Antenna stout (Fig. 13 J). Median lobe as in Fig. 8 A and parameres as in Figs 10 F, 11 D. Female. Generally identical to male in habitus; elytron sometimes dull, with distinct microreticulation between punctures. The corresponding author has seen 4 specimens with strong pronotal and elytral microreticulation from Mount Elit (IR 92 # 50). Antenna stout but without conspicuous modifications.	en	Balke, Michael, Villastrigo, Adrián, Hájek, Jiří, Surbakti, Suriani, Panjaitan, Rawati, Hendrich, Lars (2025): A review of Limbodessus Guignot, 1939 from New Guinea, with description of eight new tropical-alpine species (Coleoptera, Dytiscidae, Bidessini).
