Detailed studies of microstructure has recently been shown to provide phylogenetic signals at several supraspecific levels within leiodid coleopterans, as well as in other insects. The tribe Ptomaphagini (Leiodidae: Cholevinae), with a Holarctic-Neotropical-Oriental distribution, has been characterized, among other things, by having a comb of equal-sized, flat spines around the apex of the tibiae of all legs, with a row of spines extending along the outer edge of the protibiae in the subtribes Baryodirina and Ptomaphaginina (but not in Ptomaphagina). A pattern similar to the one in Ptomaphaginina also occurs in the Neotropical cholevine tribe Eucatopini, and this has been used to indicate a phylogenetic relationship between the two tribes (but recent phylogenetic studies have not supported such a close relationship). We here review and revise the presence and structure of periapical (here called an ‘apical crown’) and marginal (here called an ‘external comb’) combs of spines on tibiae in Ptomaphagini, using other cholevines (with and without apical tibial combs) for comparison. We find a phylogenetic signal in an apical crown of tibial spines not interrupted at the outer spur, which seems to be an additional synapomorphy of Ptomaphagini, differing from the pattern in Eucatopini and remaining cholevines with an apical comb of spines, in which the comb is interrupted. We highlight differences not previously noticed between the apical protibial armature of Ptomaphaginina and Eucatopini.

Note: Proposed as nomen oblitum by provision of ICZN 1999: Art. 23.9 (Wheeler & Miller, 2005: 34) due to lack of use as a valid name after 1899. = Agathidium Illiger, 1798: 81 (unnecessary replacement name for Volvoxis Kugelann [1794] (in part), incorrectly assumed to be preoccupied by Volvox Linnaeus [1758]).

Note: It is not clear if Illiger intended to propose a new generic name here; he did not refer the generic name to Panzer (1797), although he did refer to Panzer’s (1797: 13) species treatment of Agathidium globosum. The above treatment assumes it was an intentional proposal of a new name to replace Volvoxis. Note 1: Volvoxis Kugelann has priority for the name of this genus, but this name was rejected and replaced with Agathidium by Illiger (1798) in the mistaken belief that Volvoxis was preoccupied by Volvox Linnaeus, and this replacement name became generally accepted. However, Panzer (1797) had already used Agathidium in the same sense a year earlier, without explanation. Illiger (1798) made no mention of Panzer’s (1797) use of Agathidium so these have often been treated as independent names (e.g., Newton, 1998: 95 – 96), with Panzer’s name having priority and Illiger’s name being a junior homonym of it. All three names have the same type species as indicated above, and thus are objective synonyms. Wheeler & Miller (2005: 34) cited Article 23.9 of the Code (ICZN, 1999) to set aside priority and accept Agathidium Panzer as the valid name for the genus (nomen protectum) and treat Volvoxis as a forgotten name (nomen oblitum). Agathidium has been attributed to both Panzer and Illiger at various times, sometimes (by accident) even in the same publication (see Newton, 1998: 94, 95), but Panzer, 1797 is correct. Note 2: Revised in Hlisnikovský (1964a) and Miller & Wheeler (2005b) and Wheeler & Miller (2005). Note 3: Wheeler & Miller (2005) abandoned the use of subgenera and proposed a system of species groups, as used below, which may have some relationship to previously established subgenera. Most Mexican and Central American species are in the oniscoides species group. The rich species diversity of Mexico and Central America is obviously only partly known. Key: to species groups in Wheeler & Miller, 2005: 37. Distribution: 822 spp.—Holarctic, Africa, Oriental, northern Neotropical.

Subfamily CHOLEVINAE Kirby (= Catopinae, Leptodirinae) Cholevidae Kirby, 1837: 108 [stem: Cholev -]. Type genus: Choleva Latreille. Distribution: Worldwide. Note 1: Jeannel (1936) offered the first extensive revision of the subfamily (as family at that time), which subdivisions were afterwards revised in several instances. Note 2: Antunes-Carvalho et al. (2019) offer a phylogenetic analysis of the subfamily. Note. Tribe LEPTODIRINI Lacordaire, wrongly reported for the Neotropics: The genus Neotropospeonella Pace, 1985: 542, 1987: 195 and the species N. decui Pace, 1985: 542, 1987: 197 were described from Cueva del Guacharo, Caripe, Venezuela and placed in the tribe Lepdodirini Lacordaire [1854 (1849)], where the subtribe Neotropospeonellina Perkovsky [1997] was proposed. Perreau, 2003: 212, 216 synonymized this genus and species into Oryotus ravasinii Müller [1922], a troglobitic species of Italy, and recognized the Venezuelan record as an error based on a mislabelled specimen.

Tribe PTOMAPHAGINI Jeannel Ptomaphagini Jeannel, 1911: 193 (in table, not stated as taxonomic novelty), 1936: 52 (as “new taxon”, but referring to Ptomaphagina Hatch, 1928: 164) [stem: Ptomaphag -]. Type genus: Ptomaphagus Hellwig. Note: Gnaspini (1996) suggested abandoning the use of subtribes because he found that Ptomaphaginina is not monophyletic; however, Perreau (2000: 344) maintained its use and added a third, monotypic, subtribe, Baryodirina. The phylogenetic analysis of Antunes-Carvalho et al. (2019) recovered Baryodirus Perreau [2000] nested within “ Ptomaphaginina ”. We here maintain the use of subtribes.
