Differential diagnosis. The genus Agathocles is well recognizable with the following diagnostic characters: large (body length 13–24 mm), with robust body, widest across abdominal segment III; head only slightly broader than long with mandibular plates explanate and distinctly longer than clypeus, meeting or not in front of it; anterolateral margins of pronotum crenulate to slightly serrate; mesosternum carinate; labium reaching mesocoxae or slightly beyond, at most to metacoxae; all femora unarmed; peritreme spout-shaped, well developed; and abdominal sternites convex regularly without any tubercles or furrows.

Among SE Asian genera of Caystrini , Agathocles is most similar to Valescus (also having anterolateral margins of pronotum crenulate; 10–12 mm) and Praetextatus (anterolateral margins of pronotum smooth, 9–13 mm)—both are smaller, their scape does not reach apex of head, and mesosternum is furrowed (cf. Distant 1902; Hsiao et al. 1977; Ahmad & Afzal 1979; Chen 1983; Ahmad & Kamaluddin 1989; Ahmad & Zahid 2006b; Zahid 2006; Fan 2011).

The enigmatic genus Paramecocoris (body length 6 linien = 13.17 mm), known only from its original description, differs in having the head longer than wide and basipedicellite (IIa) as long as antennomeres III and IV combined ( Fieber 1851; Distant 1902; Zahid 2006).

The remaining genera differ in having anterolateral margins of pronotum smooth and heads distinctly wider than long with mandibular plates not explanate, continually narrowing in front of eyes, as long as or only slightly longer than clypeus, clypeus apically free in Heissocoris , Neoriazocoris , Parodius and Riazocoris ( Distant 1902; Ahmad & Afzal 1979; Ahmad & Kamaluddin 1989; Zahid 2006; Ahmad & Zahid 2012) or closed by mandibular plates in Caystrus and Hippotiscus (e.g., Distant 1902; Ahmad & Zahid 2006a; Zahid 2006; Zahid & Ahmad 2011).

The Rolstoniellini genera Exithemus and Critheus differs markedly by laterally prolonged and narrowing, rugashaped peritreme, while species of Rolstoniellus differs by conspicuously produced humeral angles of pronotum ( Distant 1902).

Etymology. Agathocles (= ἈγαθΟΚλῆς) is a Greek name, e.g. of several ancient Greek philosophers and rulers. The name is derived from agathos (= ἀγαθός) meaning good and kleos (= ΚλέΟς) meaning glory; masculine.

Neither the etymology nor the gender of the name Surenus were explicitly given in the original description. As we failed to trace it in the Latin or Greek dictionaries, the name must be considered masculine according to the Article 30.2.4 of ICZN (1999). The name is also a hemihomonym with the plant genus Surenus (family Meliaceae ).
