Remarks
: This species was described by
Calvert (1909)
based on a male collected in Coroico (
Bolivia
), including an illustration of cerci in dorsolateral view.
Sjöstedt (1918)
described
H. speciosum
based on a single male from
Peru
and illustrated cerci in dorsolateral view, as well as color pattern of abdomen in dorsal view.
Williamson (1919)
illustrated color pattern of head and posterior lobe of prothorax of
H. flavidorsum
,
De Marmels (1987)
examined the
holotype
of
H. speciosum
and illustrated cerci and coloration pattern of head and thorax, arriving at the conclusion that
H. speciosum
is a junior synonym of
H. flavidorsum
. Here, we report this species for
Colombia
, from
Putumayo Department
. Some important diagnostic characters of this species are the male cerci lacking a ventrobasal convexity (
Fig. 9H
) and provided with a very short middle process (
Fig. 9
G–H). The females of this species was so far unknown.
Description of the female

Fig. 5H
).
Prothorax
: anterior lobe black with gray central spot, middle lobe dark gray with two black dorsal spots, posterior lobe black with pale brown posterior margin (
Fig. 16K
), dorsal plate of intersternite with swollen anterior corner (

).
Pterothorax
: mesepisternum pale brown with black middorsal line and black antehumeral stripe, mesepimeron gray with black stripe, mesinfraespisternum gray with black spot, metepisternum pale brown with black stripe, metepimeron pale yellow, metinfraepisternum pale yellow with black spot (
Fig. 16G
).
Legs
: dark brown, spurs on femora about same size as space between them, except for distal three, which are longer on profemora, and the distal four longer on mesofemora; there are seven spurs on profemora, eight on mesofemora and 11 on metafemora; spurs on tibiae about two times as long as space between them, except for distal three which are shorter on protibiae and metatibiae; there are ten spurs on protibiae, seven on mesotibiae and 11 on metatibiae, tarsi and claw dark brown.
Wings
: hyaline, with brown veins and pale brown pterostigma, which covers 2.5 cells, and has slanting proximal and distal edges, 17 Px in FW and HW.
