Teloconus

description: 1. Teloconus Grouvelle, 1916: 234
—Patagonian Region (Argentina).
The type species of this genus remains without re-examination. The describer mentioned that this genus resembles Gonioryctus with the body 5.0 × as long as wide and glabrous (except for abdomen), rather short head bearing short and convergent antennal grooves, pronotum narrowly bordered at sides and with blunt anterior and posterior angles, elongate striate elytra and conical abdomen with long ultimate segment. The detailed original description of both genus and species (Teloconus mirificus Grouvelle, 1916) seems to make it possible to recognize this species in additional new specimens when they are available. The type species should be deposited in the Museo de la Plata (Facultad de Ciencias Naturales y Museo, Buenos Aires) and Muséum national d’Histoire naturelle (Paris), however, at least in the latter collection no specimen of this species has been found.
Addition to standard measurements (length of body, width in widest part of body, and hight in thorax) in this monograph the length without abdomen (from apex of frons to apices of elytra) which is frequently important when the following abdominal segments can be retracted into the previous segment to varying degree.
