( Figs 1‒6 View Figs 1‒6 , 17, 20‒21 View Figs 17‒26 )
Type locality. Chile, Aysén del General Carlos Ibáñez del Campo Region, General Carrera Province, Chile Chico.
Type material. Hඈඅඈඍඒඉൾ: J, ‘ Chile, Región de Aysén, Provincia General Carrera, Chile Chico, 12.XII.2018, Mauricio Cid Burmeister leg.’ ( MNNC). Pൺ*©ൺඍඒඉൾඌ:2 JJ 1 ♀, same data as holotype ( MNNC), 5 JJ 2 ♀♀, same data as holotype ( MCTC); 3 ♀♀, ‘ Chile, Región de Aysén, Provincia General Carrera, Chile Chico, 3.II.2018, Mauricio Cid Arcos leg.’ ( MCTC); 1 ♀, ‘ Chile, Región de Aysén, Provincia General Carrera, Chile Chico, 8.XII.2019, Mauricio Cid Arcos leg.’ ( NMPC).
Differential diagnosis. Antennae ( Fig. 17 View Figs 17‒26 ) serrate from antennomere IV; antennomeres V‒X as long as wide ( L. (A.) aonikenk sp. nov. with antennomeres V‒X wi- der than long). Pronotum ( Figs 1, 4 View Figs 1‒6 ) with pair of deep depressions before lateral margins; basal angles acutely produced ( L. (A.) sulcata and L. (A.) aonikenk sp. nov. with depressions before lateral margins shallow, basal angles blunt). Prosternum ( Figs 2, 5 View Figs 1‒6 ) red ( L. (A.) sulcata and L. (A.) aonikenk sp. nov. with prosternum metallic coloured). Scutellum ( Figs 1, 4 View Figs 1‒6 ) as an inverted regular pentagon ( L. (A.) sulcata and L. (A.) aonikenk sp. nov. with scutellum cordiform). Elytra ( Figs 1, 4 View Figs 1‒6 ) with apex without periapical teeth ( L. (A.) sulcata and L. (A.) aonikenk sp. nov. with apex of elytra with periapical teeth). Aedeagus ( Figs 20‒21 View Figs 17‒26 ) with median lobe cuneiform ( L. (A.) aonikenk sp. nov. with median lobe wide).
Description. Holotype male, 13.6 mm length; 4.8 mm width.
Head ( Fig. 17 View Figs 17‒26 ) with shallow and inconspicuous depression in interocular zone; punctuation dense and regular; pilosity long, fine, decumbent and pale white. Eyes not produced, with interior margins subparallel. Antennae ( Fig. 17 View Figs 17‒26 ) reach anterior quarter of pronotum; serrated and with sensory pits starting from antennomere IV; with moderately long sub-erect setae; antennomeres V‒X nearly as long as wide.
Thorax. Pronotum ( Figs 1, 4 View Figs 1‒6 ) distinctly wider than long; punctuation dense and irregular, coarser than on head, being stronger in anterior half; pilosity pale white, long, dense, fine and decumbent; basal half of disc with moderate to distinct depression medially and with pair of deep depressions on sides before lateral margins; lateral margin with red colour not reaching basal margin; basal margin bisinuate, with produced basal angles. Hypomerae ( Figs 2‒3, 5‒6 View Figs 1‒6 ) bright red, excluding metallic blue basal margin; punctation dense and regular; pilosity moderately long, fine and decumbent. Prosternum ( Figs 2, 5 View Figs 1‒6 ) bright red, with dense and fine setigerous punctation; pilosity moderately long, dense, fine and decumbent; basal margin with metallic blue fringe. Scutellum ( Figs 1, 4 View Figs 1‒6 ) smooth, metallic blue and regularly pentagonal.
Elytra ( Figs 1, 4 View Figs 1‒6 ) with sparse inconspicuous and long setae. Background colour bluish black. Four wide orange yellow bands reaching lateral margin of elytra; basal band reaching elytral suture after projecting slightly towards apex; second (sub-basal) band not reaching elytral suture, narrowed at middle, widened at lateral margin of elytra and connected to first band; third (sub-distal) band not reaching elytral suture, slightly curved; distal band semicircular, not reaching elytral suture nor apex. Elytral suture slightly elevated. Costae complete, almost straight, with coarse series of double punctures between each other; first costa two times wider than others in basal half and with inconspicuous fine punctation. Humeral callus as wide as first costa. Apex without periapical teeth.
Abdomen ( Figs 2, 5 View Figs 1‒6 ) metallic blue; densely and regularly punctate; and covered with long, decumbent pale white setae; first ventrite with oval red spot along middle, not reaching distal margin.
Aedeagus ( Figs 20‒21 View Figs 17‒26 ) tubular, with sides of parameres subparallel, strong longitudinal depression in two distal thirds; median lobe cuneiform, margins converging in apical portion; basal lobe narrowed by sides.
Sexual dimorphism. Apical margin of last ventrite ( Figs 2, 5 View Figs 1‒6 ) notched in males and semicircular in females.
Intraspecific variation. Apex of elytra with tooth pointed or blunt.
Measurements of paratypes. Males (n = 4): 13.3‒14.5 mm length; 5.0‒5.5 mm width. Females (n = 4) 14.0‒15.3 mm length; 5.0‒5.7 mm width.
Etymology. Named after Mauricio Cid Burmeister, who collected most specimens of this new species.
