Outer margin of the ventral membranous region straight (Figs 9, 9a), slightly curved (Figs 22, 22a, 48, 48a, 61, 68, 69) or strongly curved (35, 35a); TML/TMW 0.9–1.3, TMaL/TML 0.2–0.6 (Figs 9, 9a, 22, 22a, 35, 35a, 48, 48a, 61, 68, 69).

Diagnosis
This species group is characteristic by its broad and compact body form. It differs from dulcis species-group (sensu Kolibáč 1998[1]) and prasinatus species-group (sensu Kolibáč 1998[1]) 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.
It differs from coomani-group (sensu Kolibáč 1998[1]) by claws with a basal tooth (Fig. 57) and metatibiae with a subapical projection on the outer edge (Fig. 58).
In the integumental coloration (yellow and black), Callimerus pallidus Gorham, 1892 (Carin Hills, Chebà; Figs 79), Callimerus gorhami Corporaal, 1949 (Sumatra’s East Coast; Fig. 81), Callimerus nigroapicalis Pic, 1955 (Fujian; Fig. 84, 85), Callimerus terminalis Chapin, 1919 (Sandakan, North Borneo; Fig. 86, 87), and some species related to Callimerus insolatus Pascoe, 1860 might be similar to members of the latifrons species-group. The differences between Callimerus pallidus, Callimerus gorhami and this species group are provided in the text below. Callimerus nigroapicalis is different from this species group in pronotum longer than wide. 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 Callimerus insolatus differ from this species group in claws without a basal tooth.
Description
Size: length 7.5–11.7 mm, width 2.3–3.7 mm. Integumental color: yellow and black. Vestiture: body profusely vested with yellow pubescence; frons with dense white scales; thoracic pleuron sometimes with white scales. Head: including eyes wider than pronotum, vertex with sparse punctures. Labrum rectangular, apex straight or very slightly emarginated in the middle; mandibles stout; terminal segments of maxillary palpi digitiform, those of labial palpi elongate-triangular, both as long as their preceding segments. Eyes large, very slightly emarginated near antennal insertions, finely granulate; posterior inner margin of eyes evidently convergent towards midline, EyD subequal to EyW (ratio 1.0–1.1) (Figs 4, 15, 17, 28, 30, 41, 44, 54). Antenna short (AL/AD 1.0–1.2); antennomere I stout and bent, twice length as antennomere II; antennomere II globular; antennomere III longer than it is wide, slightly longer than antennomere II; antennomeres IV–X increasingly wider and shorter than their preceding segments, antennomeres VII or VIII to XI wider than or as long as their respective length, forming a more or less compact and oval club (Figs 14, 27, 40, 53, 71). Gula oblong, gular sutures parallel. Prothorax: wider than long (PL/PW 0.8–0.9), subapical impression of pronotum deep; pronotum constricted at base, evidently dilated before middle (Figs 4, 15, 17, 28, 30, 41, 44, 54); punctures on pronotum sparse and fine. Elytra: wider than head including eyes, EL/EW 1.7–2.3; sides parallel, sutural angle round, outer angle pointed (Fig. 70); punctures irregular and dense; without scales. Legs: tibiae without longitudinal ridge; metatibia with a subapical projection on outer edge (Fig. 58); tibial spur formula 0–1–1; tarsi formula 5–5–5, tarsomeres I–II evidently bilobed, III–IV more or less bilobed, V slender; tarsomere I of pro- and meso-tarsi as long as tarsomere II, meta-tarsomere I slightly longer than tarsomere II; tarsomere I–IV of all legs with evident pulvilli; claws with a basal tooth (Fig. 57). Abdomen: with six ventrites; male ventrite V–VI with posterior margin emarginated (Figs 13, 26, 39, 52, 65); female ventrite V with posterior margin straight, ventrite VI with posterior margin rounded. Male terminalia: tegmen tubular, sclerotized with three semi-transparent membranous regions: a pair of slit-like ones situated at dorsal-lateral sides (Figs 59–60, 66–67); the other one more or less cordiform, situated ventrally (Figs 60–61, 67–69). Outer margin of the ventral membranous region straight (Figs 9, 9a), slightly curved (Figs 22, 22a, 48, 48a, 61, 68, 69) or strongly curved (35, 35a); TML/TMW 0.9–1.3, TMaL/TML 0.2–0.6 (Figs 9, 9a, 22, 22a, 35, 35a, 48, 48a, 61, 68, 69). In some cases, an additional tiny membranous region presents at dorso-central side of tegmen (Fig. 66). Parameres strongly sclerotized, apices divergent (Figs 7–9, 59–61) or convergent (Figs 20–22, 33–35, 46–48). Phallic plate sclerotized in midline (Figs 10, 36, 49). Spicular fork: SApL/SFL about 0.3 (Figs 11, 24, 37, 50, 63).

Southeast Asia (Fig. 72).
Discussion
This species group is probably advanced groups within Callimerus s. l., as Kolibáč (1998)[1] suggested; but its sister group cannot be determined with certainty until the intra-taxonomy of the dulcis species-group (sensu Kolibáč 1998[1]) has been resolved, which nearly contains two-thirds of species of this genus.
