Ferreira PSF, Lopes JLB, Souza F, Ferreira LSF (2018)
In this paper, a new species,
Specimens were collected by light trap in the central cordillera of the Andes mountains, Cajamarca, at Tolima department of Colombia. The collection areas correspond to Veredas: Cristales La Paloma, Vereda La Luisa and include Montane Wet Forest and Very Humid Montano Low Forest, with elevations ranging from 2100 to 3200 meters above sea level. Rainfall exceeds 2000 mm/year, and temperatures are lower than 18 °C. The rugged topography is characterized by steep slopes (
Ten traps were used to take 11 samples in two areas from May 2012 to March 2013. Traps (Luiz de Queiroz model) with a UV 15-watt fluorescent lamp were installed 2 m above ground (
Male genitalia were prepared by immersing them in room temperature KOH for 24 hours until they were softened and cleared. After being rinsed in distilled water, genitalia were placed in an excavated microscopic slide containing glycerol, and the endosoma, right and left parameres, and phallotheca were dissected using a Leica M205 A stereoscope. Material was preserved in glycerin in a microvial that was the pinned below the specimen. Terminology for male genitalia follows
The holotype and paratypes are deposited in the
Medium to large size (6–10 mm), oval-elongate, covered with short, adpressed pubescence. Front striated and vertex grooved. Pronotum trapeziform, narrowed to head, strongly punctate with lateral margins rounded; calli smooth; collar shiny and well defined. Scutellum rough and punctate, shiny and swollen. Hemelytra smooth, covered with short, adpressed pubescence.

Male: endosoma with long, narrow and curved spicule tapered in apical 1/3, with apex acute; area near secondary gonopore with outer margin bearing long spine, smaller spines of different sizes, and denticles; left paramere with sensorial lobe bearing small tubercles, apex forked and twisted |
|
– | Not as above |
|
5 | Antenna yellowish; scutellum dark brown with apex and scattered spots pale; cuneus with small pale spots; hemelytron membrane darkened with many small brown spots. Male: endosoma with long spicule, apical third tapered and curved; area near secondary gonopore with enlarged apical region with serrated edge; left paramere strongly curved; sensorial lobule well developed, very small denticles on surface |
|
– | Antenna brown; scutellum dark brown with small spots at apex yellowish; cuneus with small rounded yellowish spots; hemelytron membrane darkened with numerous small yellowish spots. Male: endosoma with long, broad spicule, apex tapering and curved; area near secondary gonopore broad, its dorsal margin formed by series of denticles and acute, elongate spinelike extension; left paramere sickle-shaped with apex blunt; sensorial lobe small, rounded, dorsal surface with many small denticles and long hairs |
|
6 | Antenna yellowish; pronotum yellowish with brown spots; collar black; scutellum dark brown with apex and small spots whitish; clavus and cuneus with small black spots along claval suture; hemelytron membrane darkened with scattered small brown spots, and large pale spot close to apex of cuneus; Male: endosoma with long stout spicule, apical 1/3 bent at right angle, extreme apex tapered and twisted; area near secondary gonopore absent; left paramere with sensorial lobe developed and flattened; apex strongly curved and blunt |
|
– | Antennal segment I reddish with tiny sclerotized black dots; pronotum reddish with numerous small yellowish spots; collar reddish; scutellum with brown and yellowish spots; clavus reddish brown; cuneus with basal area dark; hemelytron membrane darkened with many small brown spots and red veins. Male: endosoma with long spicule, curved and tapering to apex; area near secondary gonopore with apical margin serrate; left paramere falciform, sensorial lobe strongly developed with long hairs, apex twisted and blunt |
