( Figs 3 View Figs 1–5 , 35–42 View Figs 16–51 , 53 View Figs 52–53 )
Gnathoncus rotundatus : MΑƵUR (2011): 176 (catalogue); LΑർΚΝΕR et al. (2015): 114 (catalogue); LΑർΚΝΕR +| LΕඌർΗΕΝ (2017): 33, figs 90–110, 754 (mentioned).
Notes. Complete synonymy and references of this species are given by LΑർΚΝΕR (2010: 118) and the reader is referred to them there. For the sake of completeness we list the references of all works containing G. rotundatus since 2010 above.
This species has been very thoroughly redescribed and figured in detail by ÔΗΑRΑ (1994: 220) and the reader is referred to the redescription there. For the sake of better recognition of this species among others spread in Southeast Asia, the habitus ( Fig. 3 View Figs 1–5 ) as well as pygidium ( Fig. 53 View Figs 52–53 ) and male genitalia ( Figs 35–42 View Figs 16–51 ) are reproduced herein. The differential diagnosis of this species is also provided.
Differential diagnosis. Gnathoncus rotundatus differs from G. semimarginatus in the complete marginal pronotal stria; from G. vietnamicus in the absence of longer apical fragment of the sutural elytral stria, and from G. sechuanus in the absence of strong alutaceous microsculpture of the elytra. From the most similar G. brevisternus it differs in much smaller, inconspicuous prosternal fovea and narrower prosternum, as well as in different structure of the aedeagus (compare Figs 41 and 23 View Figs 16–51 ). From G. nannetensis it differs in oval-shaped pygidial punctures, differently-shaped male VIII sternite and tergite (compare Figs 25–27 and 35–37 View Figs 16–51 ) and in reddish-brown legs.
Biology. A typical synanthrope found mostly in anthropogenic settings, but collected also on carrion, bird nests, excrements, decaying vegetable matter, birch sap, occasionally even in anthills (KRΥƵΗΑΝοඏඌΚιΙ +| RΕιർΗΑRƉτ 1976).
Distribution. Holarctic Region, Republic of South Africa, Chile, Saint Paul Island (MΑƵUR 2011). From SEAsia reported from Taiwan and China: Gansu (LΑർΚΝΕR et al. 2015).
