Antennae are hirsute to nearly plumose. The antennae are slightly clubbed basally with the widest point occurring at first segment of the flagellum. There are two major color regions of the antennae: a dark basal region and a light distal region. The dark basal region begins as slightly lighter than the remainder but becomes a dark black color by the end of the dark region. The 25th segment of the antennae is the final dark segment. The 26th antennal segment begins the light region of the antennae. The 26th or 27th and subsequent segments are nearly white, becoming more brownish orange

(Figure 15A). Inter-ocular space is sharply angled creating a carina that begins where the compound eye meets the antennae. The antennal pits are closer together than the eyes. Eyes are prominent and appear to bulge the head laterally. Facial grooves spanning from the posterior portion of the eye towards the mouthparts are prominent. Coloration on head is brown-orange overall with a slightly lighter, less brown, patch above and below the carina. Ocellar spots are either absent or not readily visible.

The black area is opaque and reaches forward to the anterior margin but just stops short of completion in the posterior eighth of the segment. The black region is nearly rectangular, slightly rounded anteriorly and widened posteriorly (Figure 15B). Bordering the black region laterally and posteriorly are translucent regions colored brown-orange similar to the remainder of the body.</paragraph>

<paragraph pageId="20" pageNumber="57">Meta- and meso-thoracic segments are both strongly lobed, presumably due to the developing wings within. Color is orange-brown overall with small amounts of black on the tips of the posterior pair of wing pads. Legs are light in color with a slight orange tinge overall. Dark regions are present on the medial side of the base of the fore-coxae.</paragraph>

Arolia are large and extend beyond the tips of the pretarsal claws on all legs. Claws are symmetrical and unspecialized.</paragraph>

<paragraph pageId="20" pageNumber="57">The dorsal abdomen is mostly glabrous. Hairs that are present are most dense laterally and on segments five and six. Ventral abdomen is glabrous as well, with fewer hairs than on the dorsal side and no regions with any dense pubescence. Supra-anal plate is unspecialized and broadly subtrapezoidal or triangular. Subgenital plate is broadly subtrapezoidal with the posterior margin being broader than that of the subgenital plate. The posterior margin of the subgenital plate is not perfectly uniform and conforms around two large styli. Styli are equal in length to the entire subgenital plate. Their width is equal to half of the length of the visible portion of the styli.</paragraph>

Hebard, 1921 are thought to be closely related (Hebard 1921). These are known from a number of regions (Para and Rio de Janiero Brazil, Bolivia and Panama) but there are no records from the Guiana Shield. Therefore, a new record of this species from the coastal rainforests of Guyana is geographically disjointed from all other records of these taxa. On this basis alone, we might distinguish this specimen as a new species. However, since our lone specimen is a juvenile, we have limited morphological basis for differentiating this from known taxa. We refrain from establishing this as new species until adult specimens can be found but we still give a synopsis of the biological traits of this specimen. This new record extends the potential range of
