Re-description. Measurements. TL = 2.80–2.90 mm, TL-H = 2.50–2.60 mm; MW = 1.30–1.40 mm.

Colour: Antennae, palpi and head testaceous with two darkened spots on clypeus anteriorly. Pronotum testaceous with thin blackish band basally. Elytron dark red-brown with some well marked elongate yellow markings ( Figs 1, 2). Ventral side, including legs and epipleura, reddish-yellow, prosternal process and metacoxal plates somewhat darkened.

Sculpture and structure. Elongate oblong. Head quite strongly punctate behind, punctures smaller and weaker anteriorly. Pronotum and elytron moderately microreticulate and with moderately dense strong punctures. Length of pronotal striae 1/3 to 1/2 of that of pronotum, a little incurved, finely but usually clearly impressed. Elytra lacking basal and sutural striae. Elytron with a subapical flange, terminating in a small but marked tooth. Underside laterally with scattered moderate to strong punctures, midline with dense small punctures. Metacoxal lines raised, well separated, diverging slightly in anterior half.

Male. Median lobe of aedeagus ( Fig. 19a, b). Protarsus a little expanded, mesotarsus less so. Inner edge of mesotibia a little curved.

Female. Tarsi slim, mesotibia straight on inner edge.

Affinities. The denticulate elytra ( Fig. 21) readily distinguish this species from all others. Furthermore, N. denticulatus   can be separated by the shape of the median lobe from all other species of the genus ( Fig. 19).

Distribution. Northern Australia (NT, QLD), along the east coast south to northern NSW. In Western Australia from the Kimberley region, the Pilbara south to Geraldton ( Watts 1985, 2002; Lawrence et al. 1987, Weir 1998, Larson 1997, Hendrich 2003) ( Fig. 22).

Habitat. The most widespread species of the genus and also one of the commonest dytiscids in tropical northern Australia during the dry season. Mainly collected from isolated pools of seasonal rivers and creeks without any aquatic vegetation but collections of single specimens or small numbers of beetles were made from almost all habitat types. The bottom of these habitats consisted of gravel, sand and a thin layer of decaying vegetation, mainly leaves. In the Pilbara, the Kimberley region and in Kakadu the species was collected in slow flowing streams with seasonally inundated fringing Melaleuca   woodland and numerous isolated, shallow and shaded pools (up to 20 cm depth) in river or creek beds. The species seems to be quite resistant to habitat degradation and nitrification as larger series were obtained from eutrophic and shallow cattle holes (10 m ²) in temporary and partly shaded creeks without any aquatic vegetation ( Figs 31, 32, 37, 38, 39). Neobidessodes denticulatus   shared its habitat with all other Neobidessodes   distributed in tropical northern Australia. The species is also frequently attracted to light.
