Thisiomorphus andrewsi , new species

( Figs 1 , 13 , 35)

Holotype, male, labeled: “ PANAMA: Chiriqui Prov. Reserva Fortuna Continental Divide Trail [8.695118, - 82.228355] V-26-1993 F. Andrews & A. Gilbert // [large red label] HOLOTYPE ♂ Thisiomorphus andrewsi Pollock ”, in CSCA.

Derivation of specific epithet. I take pleasure in naming this species in honor of Dr. Fred Andrews, who cocollected the holotype, as well as many other interesting specimens of Coleoptera .

Diagnosis. The only known specimen of this species has the following diagnostic features: pronotum light reddish, contrasting in color to brown elytra; lateral margins of pronotum subparallel, hind angles not markedly produced.

Description. Measurements (mm, N=1): HL = 0.88; PL = 0.76; EL = 3.04; TL = 4.68 mm; GHW = 0.96; GPW = 1.00; GEW = 1.60. Ratios: EL/GEW = 1.90; GPW/PL = 1.32; TL/GEW = 2.93; GPW/GHW = 1.04. With characters of Thisiomorphus , and the following:

Body distinctly elongate (TL/GEW 2.93), lateral elytral margins subparallel.

Color. Antennae with basal 4 antennomeres testaceous, remaining antennomeres darker, rufous; maxillary palpi rufous, distal palpomere slightly darker than preceding segments; head rufopiceous, slightly darker than rufous pronotum; scutellum rufous with darker margins; elytra uniformly non-metallic brown-piceous, apical patches visible, distinctly darker; legs uniformly rufous; venter dark rufous, prosternum somewhat lighter.

Antennae relatively elongate; antennomeres 3–7 filiform; antennomeres 8–10 relatively elongate, slightly expanded distally.

Pronotum moderately wider than long (GPW/PL 1.32), subequal in width to head (GPW/GHW 1.04); lateral margins only slightly arcuate, maximum width slightly anterior of midlength; dorsal surface evenly convex, without depressions.

Male genitalia. Parameres slightly shorter than lateral margin of basale, inner margins shallowly emarginate basally; basale with anterior margin deeply curved, lateral margins straight anteriorly, then abruptly angulate posteriorly.

Distribution. Known only from the type locality, in PANAMA (Chiriquí).
