Type genus. Tibionema Solier, 1851 .

Diagnosis. Tibionemini is proposed in Pityobiinae sensu Motyka et al. (2023b) as a monogeneric tribe. Currently, the nominotypical Tibionema is the only genus placed in it, and its diagnosis presented below is simultaneously the diagnosis of the tribe.

Tibionema has a medium-to-large body, flat pronotum and elytra ( Fig. 1A View FIGURE 1 ), distant longitudinal bulges in the pronotum, and acutely prominent posterior angles of the pronotum ( Fig. 1A View FIGURE 1 ). The prosternum is narrow, and the prosternal process is long and slender ( Fig. 1B View FIGURE 1 ). The lateral edges of the pronotum are complete ( Fig. 1E, F View FIGURE 1 ). There is a sharp keel between mesocoxae ( Fig. 1B View FIGURE 1 ). Antennae are 11-segmented and serrate; the scapus is parallelsided, antennomeres 2 and 3 are short and ball-like, and antennomeres 1–3 are almost bare and shining ( Fig. 1D View FIGURE 1 ). The abdomen has five visible segments, a short intercoxal process, a straight posterior margin of the penultimate segment, and a triangular, apically rounded last visible abdominal segment. Internal abdominal segments consist of long, narrow penultimate, and small ultimate sternites ( Fig. 1H View FIGURE 1 ). Tibionema and Pityobius differ in the number of antennomeres (twelve in Pityobius versus eleven in Tibionema ); the posterior pronotal angles bent toward the body in Tibionema (also in Hapatesus and Oxynopterus ), but not in Pityobius . Tibionema has a prominent intercoxal keel in the mesosternum ( Fig. 1B View FIGURE 1 ) that has not been observed in other Pityobiinae. Campyloxenus differs in much longer antennomere 3. The larva and pupa of T. abdominalis were described by Angulo ( Angulo, 1970).

Remark. Here, Tibionemini trib. nov. is proposed due to the unavailability of the same name published earlier by Motyka et al. (2023b). As we cannot get a response from the journal and rectify this omission in another way, we have to re-publish the description to make it valid in the sense of the Code ( ICZN 2012).
