Holotype: Male, ‘ PERU: Cuzco prov., Pikillacta , 3200 m, 24. 1. 2011, K. Dolezel leg.’ ( UPOL) . Paratypes, PERU: the same data (one male, UPOL) ; Cuzco prov., Pikillacta , X.1994, P. Gerhard col. (four males, MZSP) .

Diagnosis: Whole body black, only humeral spots brightly orange. Anterior margin of pronotum semicircular, with lateral margins almost parallelsided (whereas they are arcuately produced laterally in L. xanthomus ), posterior corners right-angled. Elytra parallel-sided, orange humeral spots small (while as long as one-fifth of elytral length and as wide as onethird of humeral width in L. xanthomus ), phallus as long as parameres.

Description: Body black, orange humeral spots small, as long as one-tenth of elytral length and as wide as one-fifth of humeral width, paired luminous spots on sternum VIII and pygidium pale. Head with small eyes, interocular distance over 2× longer than eye diameter. Antennae short ( Fig. 5C View Figure 5 ), reaching humeral region, branches of antennomeres III–X robust, spathuliform, branches of antennomeres IV–X about 4× longer than antennomere body, lamella of antennomere III a quarter shorter. Mandibles strong, arcuate ( Fig. 6A View Figure 6 ). Labrum fused to clypeus, deeply bilobed, with each lobe bearing a group of robust setae, projected anteriorly. Maxillary palps slender, terminal palpomere 3× longer than penultimate one, labial palps with terminal palpomere ovate ( Fig. 6A View Figure 6 ), both maxillary and labial palps setose.

Pronotum with anterior margin regularly semicircular, anterior corners absent, lateral margins almost parallel-sided, sometimes slightly convergent backward ( Figs 3C View Figure 3 , 4C View Figure4 ). Discal area elevated, finely punctured, glabrous, anterior and lateral edges of pronotum strongly punctured. Scutellum with lateral margins moderately convergent backward, apex obtusely triangular. Elytra about 3× longer than humeral width, widest in elytral quarter. Each elytron with four weak longitudinal costae, costa 4 diminishing in distal third, obsolete, marginal costa absent, sutural margins dehiscent in distal two-fifths.

Abdominal terga laterodistally lobed ( Fig. 7A View Figure 7 ). Sternum VIII with conical median point and small, well-marked, paired luminous spots ( Fig. 8C View Figure 8 ). Apical margin of pygidium trilobite, median extension rounded, short, half as long as slender lateral lobes, their utmost portion rounded ( Fig. 8D View Figure 8 ), syntergite asymmetrical ( Fig. 9B View Figure 9 ). Male genitalia symmetrical, distal half of phallus almost parallel-sided ( Figs 10C View Figure 10 1– C View Figure 1 2 View Figure 2 ) with apex uncleft. Parameres indistinctly shorter than phallus, their dorsobasal fused projection short, about half as long as phallobase. Female unknown. Body length: 13–15 mm, humeral width: 3.5–4 mm.
