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).
