Glenoleon parviproctus New, 1985b:48 (OD); New 1996:83 (cat); Stange 2004:105 (cat); Oswald 2018 (cat).

Diagnosis. Tibial spurs present; forewing with numerous brown marks; hind wing with a near apical mark in poststigmal area; mesonotum with broad pale longitudinal lines; pronotal short setae white; female posterior gonapophysis without cavisetae; male paramere almost indistinguishable.

Description. Lengths: forewing: 20–25 mm; hind wing: 18–22 mm.

Head ( Figs. 67 a–b): Labrum pale; with a line of elongate setae. Clypeus pale; with few elongate black setae. Frons predominantly pale, except for two curved black bands extending from the midline to above antennae; covered with few white setae. Gena pale. Vertex raised; in anterior view pale with a median black line interrupted centrally; in dorsal view mostly pale except for a black central transverse line and three black small spots posteriorly; set with short white setae. Ocular setae absent. Antennae clubbed; elongate, longer than pronotum; distance between antennae wider than scape width; scape and pedicel dark brown, flagellum brown with anterior surface generally lighter than posterior; torular membrane pale; flagellomeres almost as long as wide at base, apical ones much wider than long; all segments set with short black setae. Mandibles mostly pale to brown, with tip black. Palpi, maxillary and labial mostly pale, with scattered small dark spots; apical labial palpomere fusiform, palpimacula opening ovalshaped, located medially.

Thorax ( Fig. 67b ): Pronotum about as long as wide; posterior margin as wide as anterior; subapical furrow present; mostly pale except for some dark brown longitudinal bands, a central “Y” shaped, and two sinuous around center (enclosing a pale mark on posterior half), in some specimens the lateral bands are distally connected with the central; beset with few short black setae and many short white setae, marginal white setae usually longer. Mesonotum mostly dark brown, with two longitudinal pale bands around central region, and two rounded pale spots near wing’s base; covered with short white setae. Metanotum mostly dark brown, except for small pale areas (mostly around borders), covered with short white setae. Pterothoracic pleura mostly dark brown with some pale areas (particularly on dorsal segments and between segments); covered with white setae; Miller’s organ present.

Wings ( Fig. 67c ): Rather narrow with tip acute; anterior Banksian line present in both wings, posterior absent; veins mostly dark brown, but with some veins intercalated with white spots; beset with short black setae. Male pilula axillaris present. Forewing membrane mostly hyaline with brown marks concentrated in tip, posterior margin, pterostigma, around radial crossveins, and mediocubital area (entirely brown in some specimens); tip of pterostigma white; CuA fork located before or in the same position of RP origin; three or four presectoral crossveins; subcostal veinlets simple; posterior area narrower than prefork area. Hind wing membrane mostly hyaline except for brown marks beneath pterostigma, rhegmal area, and apex with small marks on posterior margin and a larger one on poststigmal area; pterostigma apex white; MP fork located just after RP origin; subcostal veinlets simple; one presectoral crossvein.

Legs: ( Fig. 67b ) All pairs of legs, femur elongate (> 2.5x length of coxa); tibia slightly longer than femur, which is longer than tarsi; tibial spurs surpassing T1 apex; T2, T3 and T4 about the same size, T1 slightly longer than T2, T5 longer than T1; pretarsal claws about half of T5 length; coxa, trochanter, femur and tibia set with short white setae; femur, tibia and tarsi set with short black setae, and scattered long black setae; T5 ventrally with two rows of thick, long, black setae. Proleg sense hair absent; tibia with antennal cleaning setae ventroapically; coxa dark brown with most part of anterior surface pale, trochanter pale, femur reddish brown except for base and part of posterior surface pale, tibia with posterior surface pale, anterior with three reddish brown rings; tarsi reddish brown, except for base of T1 and T5, pale. Mesoleg with same colour pattern of proleg. Metaleg with femur, tibia and T1 slightly longer than in other legs; colour pattern similar to anterior legs, except for tibia pale with tip and a sub basal ring reddish brown.

Abdomen: Mostly black with scattered pale marks (mainly on sternites medial area). Beset with short white setae.

Male Terminalia ( Figs. 68 a–c): Ectoproct posterior margin rounded in lateral view; set with elongate black setae. 9 th sternite posterior margin straight in ventral view; set with elongate black setae. Gonarcus broad and arched in posterior view. Mediuncus elongate with tip acute in lateral and posterior view. Paramere elongate in posterior and lateral view, weakly sclerotized.

Female Terminalia ( Figs. 68 d–e): Ectoproct posterior margin rounded, covered with thin elongate setae. Lateral gonapophyses rounded, smaller than ectoproct, set with few cavisetae. 7 th sternite distal margin straight in ventral view; covered with short black setae. Pregenital plate small and semi triangular. Posterior gonapophyses broad, elongate, with ventral margin elongate apically; covered with long black setae. 9 th Tergite with elongate membranous digitiform process. Anterior gonapophyses absent. Ventral membrane, gonapophyseal plates present.
