Gumilla adspersus Navás, 1912 

( Figs 2View FIGURE 2, 3View FIGURE 3)

Gumilla adspersus Navás, 1912: 189  , fig. 24 (forewing). Refs. Navás (1912), Penny (1977), Ardila-Camacho & Noriega (2014). Holotype male (NHMW).

Type-locality. “Brasil, Hetschka, Blumenan”.

Material examined. Holotype, Brasil: “ Hetschka, Blumenan ”, (1♂ NHMW). 

Distribution ( Fig. 43View FIGURE 43). “ Brasil, Hetschka, Blumenan”; probably Blumenau, state of Santa Catarina, Brazil.

Redescription. Head ( Figs 2View FIGURE 2 D, E). Labrum, clypeus, and frons pale yellow; labial and maxillary palpi pale yellow with small light brown setae; antennae pale yellow, longer than forewing, scape pale brown, as wide as long with many light brown setae, flagellum with 102 segments, flagellomeres twice as long as broad with two rings of long setae. Ocelli absent; vertex and occiput pale brown.

Thorax ( Figs 2View FIGURE 2 A, C). Prothorax pale yellow, as long as wide; entire surface of pronotum covered with numerous light amber setae arising from protuberant bases, mainly on the sides. Mesothorax and metathorax as long as wide, meso- and metanota pale yellow with some dark brown spots, mainly near to wing bases, entire surface covered with fine pale yellowish setae.

Legs ( Fig. 2View FIGURE 2 B). All segments pale yellow, procoxa almost as long as femur. Mid- and hindcoxae short; femora and tibiae with numerous small light brown setae. Tarsi and tarsal claws dark brown, arolium present.

Wings ( Fig. 2View FIGURE 2 B). Wings broad (maximum width of forewing 6.72 mm, hindwing 5.37 mm) with irregular reticulation and hyaline membrane. Light brown veins, with some dark spots. Forewing with abundant small pale setae on the wing margin; wide costal field narrowing near the wing apex, with 54 crossveins, none of them forked; pterostigmal area pale brown, with a small brown spot; whitish subcostal field with five or six elongated brown spots and with one crossvein located basally; Rs forked near to wing base, with six branches; MP forked before the midlength of wing; numerous dark amber spots on crossveins; nygmata absent. Hindwing with small pale setae on the wing margin; narrow costal field, with 44 crossveins, all of them simple; pterostigmal area hyaline; subcostal field with one crossvein basally located; Rs with six branches; dark spots and nygmata absent.

Abdomen ( Figs 2View FIGURE 2 A, B). Tergites of males light brown with some black spots, all segments covered with long light yellow setae.

Male genitalia ( Fig. 3View FIGURE 3). Ninth tergites mostly reduced; ectoproct divided into two large lobes, with two groups of elongated and brown setae; ninth sternite semi-triangular in ventral view, posteromedially bluntly produced. Complex of ninth gonocoxites terminally with two subtrapezoidal lobes, divergent and densely covered by thick, short setae, connected by a sclerite which could be the fused ninth gonapophyses; complex of tenth gonocoxites Cshaped, dorsally curved; a small unpaired sclerite probably represents the reduced eleventh gonocoxites.

Female unknown.

Remarks. Gumilla adspersus  is similar to G. longicornis  , these species have extremely elongated antennae, lack ocelli and lack nygmata. Navás in 1912 cited the type location as “ Brasil, Hetschka, Blumenan ”, this location probably refers to the city of Blumenau , capital of Santa Catarina State  , Brazil.
