==Note on Type material==
 +
The name-bearing types of ''latifrons'' and ''flavofasciatus'' were not fixed in the original publications, so lectotypes of both species are designated here to express the taxonomic purpose of fixing the name to a single specimen and preventing further uncertainty regarding the taxon to which the names are applied. Only one specimen of each species was found in related museums.

==Comment on synonymy==

Gorham (1876<ref name="B13">{{aut|Gorham H}} (1876) Notes on the Coleopterous family Cleridae, with description of New Genera and Species. Cistula Entomologica 2: 57-106.</ref >: 67) described ''{{Taxon name|Callimerus latifrons}}'' from Philippines as “Nigro-piceus, …, elytrorum fasciâ basali, maculâque pone medium reniformi pallide testaceis” (with “a basal fascia (widest in centre) and two kidney-shaped spots, almost touching suture, yellow”). Schenkling (1902<ref name="B26">{{aut|Schenkling S}} (1902) Clerides nouveaux du Museum d’histoire naturelle de Paris. Bulletin du Museum National d‘Histoire Naturelle 8: 317-333.</ref >: 320) published ''{{Taxon name|Callimerus flavofasciatus}}'' from Thailand, and stated that it differed from ''{{Taxon name|Callimerus latifrons}}'' by having an additional yellow spot at apex of elytron. Chapin (1924<ref name="B2">{{aut|Chapin E}} (1924) Classification of the Philippine components of the Coleopterous family Cleridae. The Philippine Journal of Science 25: 159-286.</ref >: 190) synonymized ''{{Taxon name|Callimerus flavofasciatus}}'' with ''{{Taxon name|Callimerus latifrons}}'' and argued, ''{{Taxon name|Callimerus latifrons}}'' having such a yellow spot at apex of elytron because all the Philippines specimens he examined having that (he also stated such a spot was mentioned in Gorham’s original description, which is not true though). Corporaal (1939<ref name="B5">{{aut|Corporaal J}} (1939) Studies in ''Callimerus'' and allied genera (Col.). Tijdschrift voor Entomologie 82: 182-195.</ref >: 193) found a specimen from Laos lacking a yellow spot at apex of elytron, which agrees well with Gorham’s description; so he regarded the specimen as a representative of the typical form of ''{{Taxon name|Callimerus latifrons}}'', and treated ''flavofasciatus'' as a variety of ''{{Taxon name|Callimerus latifrons}}'' for having an additional yellow spot at elytral apex. Corporaal (1948<ref name="B6">{{aut|Corporaal J}} (1948) Further notes on systematics and synonymy. Entomologische Berichten (Amsterdam) 12 (284): 286-288.</ref >: 287) re-treated ''{{Taxon name|Callimerus flavofasciatus}}'' as a distinct species for presence of such a spot. However, after we located it from MNHN, we found that the type of ''{{Taxon name|Callimerus latifrons}}'' actually having a yellow spot at apex of elytron, which was simply not mentioned in the original description. We compared the external morphology and male genital characters of type specimensof ''{{Taxon name|Callimerus latifrons}}'' and ''{{Taxon name|Callimerus flavofasciatus}}'' and found no significant differences; therefore, we synonymize ''{{Taxon name|Callimerus flavofasciatus}}'' with ''{{Taxon name|Callimerus latifrons}}''. In addition, the specimen from Laos mentioned in Corporaal (1939<ref name="B5">{{aut|Corporaal J}} (1939) Studies in ''Callimerus'' and allied genera (Col.). Tijdschrift voor Entomologie 82: 182-195.</ref >: 193; 1948<ref name="B6">{{aut|Corporaal J}} (1948) Further notes on systematics and synonymy. Entomologische Berichten (Amsterdam) 12 (284): 286-288.</ref >: 287) lacking the additional yellow spot is conspecific with ''{{Taxon name|Callimerus latifrons}}''; it is only the color variation of this species, as posterior black bands of elytra reach to the extreme apex and thus the apical yellow spot missing.

==Diagnosis==
−
This species group is characteristic by its broad and compact body form. It differs from ''dulcis'' species-group (''sensu'' Kolibáč 1998<ref name="B17">{{aut|Kolibáč J}} (1998) Classification of the subfamily Hydnocerinae Spinola, 1844 (Coleoptera: Cleridae). Acta Musei Moraviae Scientiae Biologicae 83 (1/2): 127–210.</ref >) and ''prasinatus'' species-group (''sensu'' Kolibáč 1998<ref name="B17">{{aut|Kolibáč J}} (1998) Classification of the subfamily Hydnocerinae Spinola, 1844 (Coleoptera: Cleridae). Acta Musei Moraviae Scientiae Biologicae 83 (1/2): 127–210.</ref >) by pronotum wider than long (PL/PW < 1; Figs 4, 15, 17, 28, 30, 41, 44, 54); antenna short (AL/AD 1.0–1.2); antennomeres VII – XI or VIII – XI forming a more or less compact and oval club, width of antennomere VIII longer than or as long as its length (Figs 14, 27, 40, 53, 71); eyes large, posterior inner margins of eyes evidently convergent towards midline, EyD subequal to EyW (ratio 1.0–1.1) (Figs 4, 15, 17, 28, 30, 41, 44, 54); elytra without scales; integument with yellow and black coloration.<br />
+
''{{Taxon name|Callimerus latifrons}}'' can be rapidly distinguished from other species of this species group by its entirely black pronotum (Figs 1, 2).<br />
−
It differs from ''coomani''-group (''sensu'' Kolibáč 1998<ref name="B17">{{aut|Kolibáč J}} (1998) Classification of the subfamily Hydnocerinae Spinola, 1844 (Coleoptera: Cleridae). Acta Musei Moraviae Scientiae Biologicae 83 (1/2): 127–210.</ref >) by claws with a basal tooth (Fig. 57) and metatibiae with a subapical projection on the outer edge (Fig. 58).<br />
+
There are 3 other species of this species group with two black spots on each elytron: ''{{Taxon name|Callimerus latesignatus}}'', ''{{Taxon name|Callimerus pectoralis}}'' and ''{{Taxon name|Callimerus rusticus}}''. In addition to the difference in pronotal coloration, ''{{Taxon name|Callimerus latifrons}}'' can be differentiated from these three species by: (1) EL/EW about 2.2 (in other 3 species 1.7–1.8); (2) anterior black spot of elytron spanning from elytral outer margin to suture, thus forming a complete black band across elytra (Fig. 1); (3) apices of paramere divergent (Fig. 7–9).
−
In the integumental coloration (yellow and black), ''{{Taxon name|Callimerus pallidus}}'' Gorham, 1892 (Carin Hills, Chebà; Figs 79), ''{{Taxon name|Callimerus gorhami}}'' Corporaal, 1949 (Sumatra’s East Coast; Fig. 81), ''{{Taxon name|Callimerus nigroapicalis}}'' Pic, 1955 (Fujian; Fig. 84, 85), ''{{Taxon name|Callimerus terminalis}}'' Chapin, 1919 (Sandakan, North Borneo; Fig. 86, 87), and some species related to ''{{Taxon name|Callimerus insolatus}}'' Pascoe, 1860 might be similar to members of the ''latifrons'' species-group. The differences between ''{{Taxon name|Callimerus pallidus}}'', ''{{Taxon name|Callimerus gorhami}}'' and this species group are provided in the text below. ''{{Taxon name|Callimerus nigroapicalis}}'' is different from this species group in pronotum longer than wide. ''{{Taxon name|Callimerus terminalis}}'' is different from this species group in claws without a basal tooth, subapical projection on outer edge of metatibia rudimental, pronotum longer than wide. Species related to ''{{Taxon name|Callimerus insolatus}}'' differ from this species group in claws without a basal tooth.

'''Variation'''. The posterior black spot on elytron in most cases doesn’t reach to the extreme apex and thus a small region of elytron extreme apex is yellow. But in a few specimens the black spot reach to the extreme apex, so the yellow portion is missing. These two color forms could be found in the same locality (Yunnan, China for instance) and they are not correlated with sex.<br />

Name

Callimerus latifrons Gorham, 1876 – Wikispecies link – Pensoft Profile

  • latifrons Gorham, 1876: 67 (Callimerus; type locality: “Philippines”); –Chapin 1924[1]: 190 (Brachycallimerus); –Kolibáč 1998[2]: 176 (Callimerus).
  • flavofasciatus Schenkling, 1902: 320 (Callimerus; type locality: “Siam”); –Schenkling 1916[3]: 220 (Singapore); –Chapin 1924[1]: 190 (synonymized with latifrons Gorham); –Corporaal 1924[4]: 196 (synonym of latifrons Gorham); –Corporaal 1939[5]: 193 (variety of latifrons Gorham); –Corporaal 1948[6]: 287 (raised to species rank). Syn. n.

Type material examined

Lectotype of Callimerus latifrons Gorham designated here: “Phill. Isles / Callimerus latifrons Gorham [hw. by Gorham] / ♂ / Gorham Type / Museum Paris, Coll. H.S. Gorham 1911 / Lectotype: Callimerus latifrons Gorham, 1876 ♂, des. Yang G. Y., 2011” (MNHN, ♂; Figs 1–3); Lectotype of Callimerus flavofasciatus Schenkling designated here: “327–62 / Museum Paris; Siam; Bocourt 327-62 / Callimerus flavofasciatus Schklg. Type! [hw. by Schenkling] / Type / ♂ / Type / Lectotype ♂: Callimerus flavofasciatus Schenkling, 1902, des. Yang G. Y., 2011” (MNHN, ♂; Figs 4–6).

Note on Type material

The name-bearing types of latifrons and flavofasciatus were not fixed in the original publications, so lectotypes of both species are designated here to express the taxonomic purpose of fixing the name to a single specimen and preventing further uncertainty regarding the taxon to which the names are applied. Only one specimen of each species was found in related museums.

Comment on synonymy

Gorham (1876[7]: 67) described Callimerus latifrons from Philippines as “Nigro-piceus, …, elytrorum fasciâ basali, maculâque pone medium reniformi pallide testaceis” (with “a basal fascia (widest in centre) and two kidney-shaped spots, almost touching suture, yellow”). Schenkling (1902[8]: 320) published Callimerus flavofasciatus from Thailand, and stated that it differed from Callimerus latifrons by having an additional yellow spot at apex of elytron. Chapin (1924[1]: 190) synonymized Callimerus flavofasciatus with Callimerus latifrons and argued, Callimerus latifrons having such a yellow spot at apex of elytron because all the Philippines specimens he examined having that (he also stated such a spot was mentioned in Gorham’s original description, which is not true though). Corporaal (1939[5]: 193) found a specimen from Laos lacking a yellow spot at apex of elytron, which agrees well with Gorham’s description; so he regarded the specimen as a representative of the typical form of Callimerus latifrons, and treated flavofasciatus as a variety of Callimerus latifrons for having an additional yellow spot at elytral apex. Corporaal (1948[6]: 287) re-treated Callimerus flavofasciatus as a distinct species for presence of such a spot. However, after we located it from MNHN, we found that the type of Callimerus latifrons actually having a yellow spot at apex of elytron, which was simply not mentioned in the original description. We compared the external morphology and male genital characters of type specimensof Callimerus latifrons and Callimerus flavofasciatus and found no significant differences; therefore, we synonymize Callimerus flavofasciatus with Callimerus latifrons. In addition, the specimen from Laos mentioned in Corporaal (1939[5]: 193; 1948[6]: 287) lacking the additional yellow spot is conspecific with Callimerus latifrons; it is only the color variation of this species, as posterior black bands of elytra reach to the extreme apex and thus the apical yellow spot missing.

Diagnosis

Callimerus latifrons can be rapidly distinguished from other species of this species group by its entirely black pronotum (Figs 1, 2).
There are 3 other species of this species group with two black spots on each elytron: Callimerus latesignatus, Callimerus pectoralis and Callimerus rusticus. In addition to the difference in pronotal coloration, Callimerus latifrons can be differentiated from these three species by: (1) EL/EW about 2.2 (in other 3 species 1.7–1.8); (2) anterior black spot of elytron spanning from elytral outer margin to suture, thus forming a complete black band across elytra (Fig. 1); (3) apices of paramere divergent (Fig. 7–9).

Description

Size:length 7.5–8.9 mm, width 2.3–2.8 mm. Color: Head black, clypeus, labrum, palpi and antennae yellow; pronotum black; elytron yellow with two black spots, anterior spot just before middle, posterior spot near apex or at apex, both spots spanning from elytral outer margin to suture, thus forming two complete black bands across elytra; legs yellow with metacoxae black; prosternum black; mesepisternum black, mesepimeron yellow, mesosternum black with anterior and posterior areas more or less yellowish; metepisternum, metasternum and katepisternum black; abdominal ventrites I–III of male yellow, IV–VI black; abdominal ventrites I–V of female yellow, VI black. Vestiture: meso- and meta- pleuron more or less with thin white scales. Head: AL/AD about 1.0; EyD/EyWabout 1.0. Prothorax: PL/PW about 0.9. Elytra: EL/EW about 2.2. Male terminalia: apices of paramere divergent (Figs 7–9); TML/TMW about 1.2, TMaL/TML about 0.4, outer margin of ventral membranous region straight (Figs 9, 9a); SApL/SFL about 0.3 (Fig. 11); tergite VIII with posterior margin rounded and slightly pointed (Fig. 12); sternite VIII with posterior margin roundly concave (Fig. 13).
Variation. The posterior black spot on elytron in most cases doesn’t reach to the extreme apex and thus a small region of elytron extreme apex is yellow. But in a few specimens the black spot reach to the extreme apex, so the yellow portion is missing. These two color forms could be found in the same locality (Yunnan, China for instance) and they are not correlated with sex.
