Hi All,
in a work in preparation we would like to give in a few sentences a short review on non-feeding scarab adults.Could you guys give us a help to make this thing more complete?There are in literature some vague statements such as this of Ritcher (1958) and Scholtz (1990) about nonfeeding Rutelinae and Dynastinae, for which I could find so far no precise data on taxa and references. Maybe I have overlooked other references…In order to avoid notification already known to us, I attached below the list I could make so far…Thanks to all in advance who may help!CheersDirkps. Do we have this pattern (i.e., nonfeeding of adult specimens) also among dung beetle lineages (Aphodiinae/ Scarabaeinae)?
Non-feeding in Scarabaeoidea
· Diphyllostoma (Lucanidae; nonfunctional mandibles; maxillae with a small rounded galea; Nel & Scholtz 1990)
· Amphicoma, Lichnanthe (Glaphyridae; Ritcher 1958; Sabatinelli et al. 2020)
· Pleocoma (Pleocomidae; Ritcher 1958; nonfunctional mandibles; maxillae with a small rounded galea; Nel & Scholtz 1990
· Pachypus (Pachypodiini; Crovetti 1968)
· Ceramida (Tanyproctini; very simple and reduced mouthparts; Sanmartin & Martin-Piera 2000; some more candidates with reduced epipharynx: Alaia, Atanyproctus, and Otoclinius)
· Aclopus (Aclopinae; reduced galea, simple epipharynx; Nel & Scholtz 1990)
· Xenaclopus (Melolonthinae, s.l. (Ocampo & Vaz de Mello 2008): reduced galea, simple epipharynx; Nel & Scholtz 1990)
· Scapanoclypeus ("Tanyproctini" (see Eberle et al. 2018); epipharynx reduced, galea, lacinia, ligula absent; Nel & Scholtz 1990)
· Sebaris, Pseudachloa, Eucyclophylla (Melolonthinae, s.l.; galea oval with setae; group 4 and 5; Nel & Scholtz 1990)
· "There are species in each of the subfamilies Melolonthinae, Rutelinae, and Dynastinae which do not feed at all in the adult stage" (without specifications; Ritcher 1958, Scholtz 1990)
