Abstract:

ABSTRACT: A new species of Aciliini diving beetles, Thermonectus tremouillesi sp. nov., is described on the basis of adult and larval specimens collected in shaded forest ponds in Argentina. The adults are compared with morphologically close species and diagnosed by the following combination of characters: the colour pattern on pronotum and elytra; the sexual sculpture of the female well marked, covering basal fourth to basal half of elytra; the male protibia narrow with dorsal margin slightly prominent; the tergite IX of male with four posterior projections; the median lobe of aedeagus bifid apically; and the parameres bearing a terminal spur. The larvae, for their part, are compared with those of other species of the genus and diagnosed by the colour pattern of the cephalic capsule, the shape of the nasale, the spinulae on the prementum, and several chaetotaxic features. Both adults and larvae are illustrated in detail combining scanning electron microscope images, digital photos and line drawings of selected structures. The habitat of the new species and its associated fauna are briefly described. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
