Calomera, Motschulsky, 1862

Key to species of the Calomera decemguttata species-complex

Universal characters: mandibles normally shaped: each mandible with four teeth (and basal molar). Some adults of species with primarily densely setose genae and proepisterna may have the setae partly or almost entirely abraded, which might cause identification problems (moreover, dorsolateral pronotal areas are primarily variably setose, thus often unreliable for identification). Aberrant adults with anomalously reduced elytral maculation ( Figs 73–74 View FIGURES 65–74 ) are not included in the key – they might be identified only by setosity of genae or shapes of aedeagi, but aedeagus apex is similar and variably shaped in all species except for C. paradecemguttata sp. nov.

1 Head and pronotum deep coppery with mostly reddish reflections, mostly notably prevailingly reddish-cupreous on pronotum. Elytral maculation yellowish or pale orange-yellow, conspicuously wide, laterally adjacent to outer elytral margin. Labrum 4–6–setose, but sometimes possessing 7–8 setae. Body large, 13.5–15.5 mm long. Dorsolateral pronotal margins with rows of numerous transverse white setae. Genae glabrous................................... C. mamasa Cassola & Brzoska View in CoL

– Head and pronotum variously coloured but pronotum only exceptionally conspicuously bright reddish. Elytral maculation ivory-whitish, yellowish or with orange tinge, of various pattern. Labrum primarily with 6 setae. Body medium-sized to large ................................................................................................... 2

2 Genae glabrous, or with few setae at their ventral margin; proepisterna with only occasional setae at their ventral suture and microsetae on proepisternal ventral half. Elytral maculation either almost adjacent to outer elytral margin, or notably distant from it. Pronotal dorsolateral margins almost or entirely glabrous............................................... 3

– Genae and proepisterna primarily rather densely setose on their ventral half. Elytral maculation rather variable, but lateral maculae always adjacent to outer elytral margin. Setae along pronotal dorsolateral margins mostly abundant (primarily, yet setae may be easily abraded)............................................................................ 6

3 Elytral maculae isolated and notably spaced (central macula rarely indistinctly thinly connected with lateromedian one), lateromedian macula placed more anteriad, while smaller, elongate, slightly posteriad-placed lateral spot is aligned or almost at the same level with central macula......................................................... C. cabigasi Cassola View in CoL

– Elytral maculae generally larger and less spaced, lateromedian macula closer to central spot or connected with it by narrow stripe but not in shape of continuous lateromedian band....................................................... 4

4 Lateromedian macula almost adjacent to outer elytral margin and closer to central macula or connected with it with a narrow stripe but not forming entire lateromedian band; some adults with small, additional basal spot. Head and pronotum deep olivaceous-green with bright green and less distinct, faint cupreous reflections; margins of pronotal disc subtrapezoid, almost or entirely glabrous. Labrum mostly with almost effaced anterolateral teeth and with only shallow or indistinct excision on either side of median tooth........................................................................ C. jakli Schüle View in CoL

– Lateromedian macula distinctly or always at least perceptibly distant from the outer elytral margin; small (elongate) lateral macula sometimes absent. Labrum with rounded or subacute anterolateral teeth and distinct excision on either side of median tooth............................................................................................... 5

5 Head and pronotum deep coppery with faint reddish-cupreous and green reflections; pronotal surface only very finely rugulose, setae along pronotal lateral margins sparse or more copious. Elytra black-brown, sometimes with olivaceous tinge; subhumeral macula obliquely ovaliform; female upper-discal catoptric area conspicuous, iridescent green or reddish.............................................................................................. C. decemguttata (Fabricius) View in CoL

– Head and pronotum deep olivaceous with coppery sublateral and posterior areas and faint or bright green-blue and violet reflections; pronotal surface with somewhat coarser sculpture, setae along pronotal lateral margins absent or very sparse. Elytra velvety black; subhumeral macula rounded or at least always shorter; female upper-discal catoptric area indistinct............................................................................................ C. bordonii Wiesner View in CoL

6 Elytral maculation extremely variable, yet in majority of adults reduced to small lateral maculae and central spot, but rarely adults with extremely dilated maculation also occur, to the measure that consisting of entire humeral lunule and wide, continuous lateral band. Pronotal surface sculpture almost effaced. Aedeagus apex with blunt noose-like dorsal portion; lateral edges in dorsal view continuous, lacking indentation................................................ C. durvillei (Dejean) View in CoL

– Elytral maculation generally regular (apart from very rare aberrant specimens), lateromedian macula connected into continuous, cranked lateromedian-discal band. Pronotal surface vermicular-rugulose. Aedeagus apex differing from all preceding species both in its lateral and dorsal aspects: dorsally sharpened in its left lateral view; lateral edges with distinct indentation in dorsal (and ventral) view..............................................................
