Diagnosis.

Distinguished among species of Glyptocombus by dark brown coloration, elytriform forewings in both sexes, forewing veins wider than cells, absence of areoles in forewing cells, and all legs with tibia and femora pale (Figure 1). Most similar to G. saltator based on wingtype in both males and females, but differentiated by much wider veins.

Description.

Male (Figure 1): with elytriform forewing, length: 1.18-1.74 mm; body ovoid. Coloration: head and body dark brown to black, coxae light brown, rest of legs pale to yellow, genital capsule and genitalia light to dark brown. Surface and Vestiture: in frontal orientation forefemur without anterior stout seta, hind tibia withtwoerect medium-length setae ventrally on distal half, second tarsomere of hind leg with stout seta anteroventrally (Figure 1). Structure. Head: disc declivous. Thorax: ratio of pronotal collar length to pronotum length 0.30-0.32, pronotal collar slightly depressed below pronotum (Figure 1), posterior margin of postnotum curved, ratio of height of forefemur to length of forefemur 0.20-0.23, ratio of length of hind tibia to width of pronotum 1.00, wing venation as in Figure 2B, forewing elytriform, with veins wider than cells. Abdomen and genitalia: as in genus description (Figure 3A, B).

Female (Figure 1): with elytriform forewing, length: 1.51 mm; body ovoid. Coloration: similar to male. Surface and vestiture: forefemur with anterior stout seta, hind tibia with four erect medium-length macrosetae ventrally on distal half, second hind tarsomere with two stout setae anteroventrally (Figure 1), entire surface of sternum 7 shiny with long setae (Figure 1). Structure. Head: disc decurrent anteriorly. Thorax: similar to male, but ratio of pronotal collar length to pronotum length 0.28, collar slightly depressed below pronotum (Figure 1), postnotum short and rectangular, ratio of height of forefemur to length of forefemur 0.26, ratio of length of hind tibia to width of pronotum 1.00, forewing similar to male. Abdomen and Genitalia: as in genus description (Figure 3C, D).
