Habitus. BL 2.3−3.6mm, BL/BW ~1.6. Body elongate oval. Surface punctures are very fine everywhere, finest on head. The pilosity is yellowish. Most specimens are yellowish brown, with a small brown spot at the highest point of the elytra, next to the suture, a little behind midlength (Fig. 165). Sometimes, specimens are darker with brown head and pronotum and brown maculae on the elytra reaching obliquely forward to the elytral margin, and back along the side. All marks are diffusely delimited. Appendages yellowish to light brown, antenna distally infuscate.
Male (Figs. 8−10). Segments 8 and 9, as described for the genus. On a transparent membrane between S9 and the penis stands a slender backward pointing spine-like hollow cone which points basad on the everted penis (Figs. 8, 10). Pala large, front rounded. The penis narrows caudally, a continuous sclerite extends from the sides of the pala to the apices of the parameroids. A slight medial fold or crest suggests there is a delicate cover over the entire pala. The basally wide bulbous trigonium narrows caudally. Its apex is expanded in dorsoventral direction and carries on each side a row of strong teeth. In precisely dorsoventral view the two rows are separate, in oblique or in side view the apex resembles a rooster with a crest. The trigonium is much shorter than the rod-like parameroids. Their expanded apex is beset with sensillar pores, some colourless membrane attaches to the outside. The tegmen is a large ventrally split colourless sleeve surrounding the penis. On each side it supports one very large spine (Figs. 8, 10), homology with parameres uncertain. At high magnifications the spine appears longitudinally twisted.
Female. Front ends of rods of S8 connected by a sclerotized ring (compare Fig. 15, N. ypsilon, which is similar). T8 and ovipositor unmodified. Prehensor (Fig. 14) composed of a loop-shaped narrow sclerite armed with some spinules and anterolaterally from it two bands of large tooth-like scales on one side of the oviduct, and on the opposite side an anteriorly bilobed sclerite which bears two elongate rough areas with irregular polygonal structure (Fig. 14 a). Medially a sclerotized nipple projects into the lumen of the duct, standing vertical on its wall (Fig. 14 b).
Notes. Klausnitzer (1981) realized that H. lindensis does not belong in genus Elodes but provisionally accepted the original combination. He mentioned faint elytral ribs which I have not seen. The species is externally indistinguishable from N. ypsilon n. sp. Blackburn, Lea, and other students did not study the genitalia and failed to distinguish the taxa whose ranges overlap.
N. lindensis inhabits an exceptionally wide range on the mainland but is not known from Tasmania. Larvae of N. lindensis live in “still water in dams or side pools of small creeks or in trapped leaf masses” (Watts 2014).
Nyholm (1969) documented how during copula of European Contacyphon spp. the prehensor (Latin: the grasper) is extruded into the male gonoduct and seizes the spermatophore. Among material from coll. Armstrong a pair taken in copula was glued on one card, but only the female remains. Its prehensor protrudes between the components of the ovipositor in a way similar to what Nyholm described. It may function in a similar way.
