This paper describes the first four known species of
The material studied here is deposited in the entomological collection Instituto de Investigación de Recursos Biológicos Alexander von Humboldt (
The specimens were collected in pristine ecosystems using Malaise trap and sweeping net (Fig.
Photographs were taken using a Moticam 3.0 megapixel digital camera attached to an Olympus SZX7 stereomicroscope and with a Leica DFC500 camera coupled to a Leica M16 stereomicroscope. Photo stacking was performed using the Helicon Focus 6.7.2 software and edited with Adobe Photoshop CC 2017. Photographs and illustrations of the terminalia were prepared using the U–DA Olympus drawing tube attached to an Olympus BX40 compound microscope, then vectorized with Illustrator CC 2017.
Morphological terminology for head, thorax, pleural sclerites and terminalia follows
(modified from
1 | Wing membrane with obvious dark maculae (Fig. |
|
– | Wing membrane clear or with faint darkened areas along anterior margin but no obvious maculae (Fig. |
|
2 | Vein sc-r almost aligned with Rs (Fig. |
|
– | Vein sc-r not aligned with Rs (Fig. |
|
3 | Terminalia with long, slightly inwards curved dorso-lateral projection of gonocoxite; small and rounded gonostylus; thin cerci (Fig. |
|
– | Terminalia with small dorso-lateral projection of gonocoxite; wide and lunular gonotylus; wide cerci (Fig. |

General color yellow to light brown. Anepisternum bare. All coxae and hind femur with no dark markings. Wing darker along anterior margin, but without conspicuous maculae; sc-r beyond origin of Rs. Terminalia yellowish, wider than long. Lateral extension of gonocoxite long, slightly curved inwards, with an apical long dark spine. Gonostylus small and rounded, apical surface with scattered short spines. Parameres digitiform, apically bifurcated, with short dark spines.
Head, frontal view
The specific epithet of this species combines the Latin word
This species is easily discriminated from the other species described here by the faint darkened wing membrane along the entire anterior margin, the elongated, thin cerci, the long dorso-lateral projection of gonocoxite extending well beyond the gonostyle, bearing a distal spine, and the parameres with a pair of distal spinose projections.
Body light brown. Anepisternum bare. Coxae and hind femur without maculae. Wing membrane translucent; sc-r beyond of origin of Rs. Terminalia yellowish, wider than long. Dorso lateral-distal extension of gonocoxite short, with a distinctive apical spine. Gonostylus wide and lunular, inner surface with abundant spines. Cercus elongate, but wide on basal half. Paramere not bifid, elongate, with short spines.

The specific epithet of this species
This species can be clearly separated from
Male terminalia of
Scutum with a wide dark brown band. Anepisternum with a set of short dorsal setae. Coxae darkened distally, hind femur with a blackish brown marking on basal third. Wing with a dark brown macula along margin at region of sc-r, base of Rs and R4, r-m, bM, M1+2 and base of medial fork and over entire apical third. Abdomen blackish brown except in the basal third of each segment. Terminalia as long as wide, with short dorso-lateral projection of gonocoxite bearing a strong distal spine. Cerci very long, wide basally and setose. Paramere bifid, apically rounded and wide, with long dark spines on the margin.
Male terminalia of
The specific epithet
This species is present in the transitional “dwarf forests” (Fig.
Body yellow to light brown. Anepisternum with a set of dorsal short setulae. Mid coxae and hind femur with dark markings. Wing with conspicuous maculae; sc-r reaching C beyond M1+2 fork, at apical third of wing. Terminalia yellowish, with dorsal margin dark brown, lateral rounded apical extension with apical long dark spine.
Male terminalia of
Female terminalia of
The species epithet of
This species is very similar to
These four Colombian species can be easily separated from each other, as indicated along the remarks for each species above, based on different aspects of the morphology of the species, as the color of the head and the scutum, setation of the anepisternum, wing membrane maculation and details of the wing venation, and the male terminalia.
Not much can be said about the relationships between the Colombian species and other species of
All the four species from Colombia described here,
These fragile ecosystems have been seriously damaged (
