Diagnostic description. Light reddish brown, shining. Length of pronotum + elytra = 2.5–2.7 (males), 2.7–2.8 (females). Head finely, irregularly punctate. Pronotum broad, widest at base, sides rounded, posterior angles obtuse; ratio length:width = 1:1.7; finely punctate with faint reticulate microsculpture. Elytra short, wider than pronotum, ratio length:width = 1:0.8; with 9 regular, closely punctate striae; striae 6 and 7 do not reach apex, stria 8 does not reach base, stria 1 weakly impressed; intervals minutely punctate, transversely striolate. Antennal club ( Fig. 167 ) moderately slender, ratio club width:length = 1:3.4; width ratio of antennomeres 7:8:9 = 1.2:1:1.5. Mandibles ( Fig. 168 ) stout, each mandible with a subapical tooth on inner margin. In both sexes, all femora unarmed; all tibiae slender, spinose on outer margin, protibiae and mesotibiae weakly widened apically, male mesotibia weakly curved. Male. Aedeagus ( Fig. 169 ) with median lobe elongate, apex broadly rounded. Parameres longer than median lobe, flat, with lateral lobes near base. Paramere apices thin, narrowed to acute tips, with two dorsal setae and many small setae at apex. Female. Coxites ( Fig. 171 ) elongate, narrow, with apical and subapical setae; styli moderately elongate, slender, inserted at apices of coxites. Sternite 8 ( Fig. 170 ) rounded apically, anterior apophysis truncate apically.

Bionomics and distribution. The type and paratype specimens were taken in August–September in flight-intercept traps in mid-elevation wet forests ( Fig. 160 ).

Etymology. Named with reference to the type locality, Parque Nacional La Tigra, Distrito Central,

Honduras.
