Diagnosis.
Differing from
G. interpretatus
,
G. p i c t u s
, and
G. trypetoides
, in having the forewings without brown spots. Differing from
G. enderleini
, in having the distal half of the pterostigma pigmented and in having the areola postica narrower. Differing fom
G. lacteus
, in having the distal half of the pterostigma pigmented, and in having the areola postica distinctly narrower. Differing from
G. peruvianus
, in having the phallosome anteriorly unstemmed, in the shape of the endophallic sclerites, and in lacking clunial projections over the area of the epiproct and paraprocts. Differing from
G. va r t y i
in the shape of the hypandrium, in lacking clunial posterior projections, and in the endophallic sclerites.
Color
. Body dark brown, compound eyes black, legs yellow, forewings yellow, veins brown; pterostigma brown yellowish, hindwings hyaline, with a yellowish hue. Tergal lobes of meso- and metathorax dark brown, abdomen creamy.
Morphology.
As in diagnosis plus the following: Head vertex almost straight, compound eyes prominent, upper borders above the level of the vertex, with interommatidial setae (
Fig. 22
). Forewing L/W: 3.0. Forewing pterostigma elongate, much wider posteriorly, with setae in the membrane; lp/wp: 3.38. Areola postica triangular (
Fig. 21
). Hindwing L/W: 2.59 (
Fig. 21
). Hypandrium broad, setose, posterior projection with postero-lateral corners rounded distally (

Fig. 24
). Posterior border of clunium not projected over the areas of paraprocts and epiproct (
Fig. 23
). Paraprocts (
Fig. 23
) broad, with few setae, restricted to the latero-posterior areas; sensory fields with 17 trichobothria in basal rosettes. Epiproct (
Fig. 23
), triangular, with rounded apex, and three macrosetae in the posterior border.
