( Figs. 160 , 163–164 )

Type material. Holotype: ♂ ( CMNC). MEXICO: Chiapas State: Mpio. [Municipio] Tapalapa, Cerro El Calvario, near Tapalapa , 17°11'11.9"N, 93°07'21.0"W, 23.VII.2003, 2200 m, R. Anderson, 2003-119. wet cloud forest litter . Paratype: MEXICO: Chiapas State: same data as holotype, ♂ ( SBPC) .

Diagnostic description. Reddish brown, shining; elytral bases with a transverse yellow band; elytral epipleurae yellow. Length of pronotum + elytra = 2.7–3.0 mm (males). Head finely punctate. Pronotum broad, widest at base; sides rounded; basal angles obtuse; ratio length:width = 1:1.75; finely punctate with fine 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. 163 ) moderately slender, ratio club width:length = 1:3.3; width ratio of antennomeres 7:8:9 = 1.4:1:1.7. All femora unarmed; all tibiae slender, spinose on outer margin, protibiae and mesotibiae weakly widened apically, mesotibia weakly curved. Male. Aedeagus ( Fig. 164 ) with median lobe elongate, apex truncate. Parameres longer than median lobe, flat, with small lateral lobes near base. Paramere apices thin, weakly inwardly curved, with two setae dorsally before apex and many small setae at apices. Female. Unknown.
