Lycomorphon (Spinolycus) bolivianum sp. n.

( Figs. 5 , 18 , 47–49 )

Holotype, male, BOLIVIA ‘Yungas Coll. Kraatz’ ( MNHN).

Diagnosis. Elytra with 3 longitudinal costae, yellow with dark brown ornaments. Pronotum 1.2 times wider medially than pronotal length. Phallus rounded apically, with distal half curved dorsally, paramerae slightly shorter than third of phallus length. Phallobase wider than paramerae, almost square in ventral and dorsal views.

Description. Interocular distance 1.6 times longer than eye diameter. Antennomeres 3–5 with same length ( Fig. 18 ). Mandibles reduced, almost L-shaped, maxillary palpi with tips slightly truncate, labrum as long as wide, its anterior margin rounded. Pronotum trapezoidal, 1.2 times wider medially than pronotal length, dark brown with lateral margins yellow, median longitudinal carina simple in anterior half, forming longitudinal groove posteriorly. Elytra elongate, each elytron yellow with dark brown J-shaped macula from the base of sutural costa to the middle of elytron and with dark brown transversal band in distal quarter. Each elytron with 3 costae, costa 3 entirely absent, costa 1 shortened, missing apically, reticulate cells square to rectangular, irregular. Abdominal sternum 8 rounded with three emarginations distally, median emargination as long as ½ of sternal length ( Fig. 5 ). Sternum 9 elongate, rounded proximally, triangular distally. Phallus with distal half curved dorsally, apex rounded, teary orifice in distal two thirds. Paramerae slightly shorter than half of phallus length, rounded apically in lateral view. Phallobase semicircular in lateral view, almost square in ventral and dorsal views ( Figs. 47–49 ). Body length: 9.2 mm, humeral width: 2.5 mm.

Etymology: the name refers to the species occurrence site.

Distribution: Bolivia.
