  Type species:

   Guttala mona Löcker & Larivière, 2006 by original designation.

Introduction

This is one of the more distinctive genera in the Gelastocephalini with the apical part of the tegmen bearing 2-3 dark bullate spots or markings. It is from these that the generic name has been derived. The four species recognised by Löcker et al. (2006) are all restricted to the Northern Territory. A number of female specimens, also from the Northern Territory, can be placed in this genus but identification to species requires examination of the male genitalia.

Diagnosis

Colour. Frons dark brown with yellow lateral carinae, clypeus mid brown, or entire face orange except for yellow lateral carinae; mesonotum mid brown or orange; legs straw coloured to light brown; forewing hyaline light brown except for large colourless area along costa, colourless marks in apical cells, brown stripes apically on Sc and R, dark (mostly bullate) spots or streaks apically on MA1 and MA2 and sometimes on MP1, one more or less distinctive brown mark at apex of clavus, with or without brown marks apically on CuA1 and CuA2, veins concolorous with cells, tubercles in some areas light brown in others dark brown; abdominal sternites yellow, intersegmental membranes yellow. Morphology. Body length. ♂ 5.1–5.4 mm, ♀ 5.6–6.0 mm. Head. Vertex produced before eyes by less than 1/4–1/2 of an eye length; apex broadly truncate; caudal border u-shaped; lateral carinae moderately to strongly elevated. Frons 1.1–1.5× longer than wide, position of maximum width distinctly ventrad of centre of frontoclypeal suture; lateral carinae (slightly) s-shaped, moderately to strongly elevated, lateral margins foliaceous, concealing base of antennae; median carina absent. Frontoclypeal suture semicircular, median part reaching at least lower margin of antennal scape; anteclypeus lacking carinae. Thorax. Hind margin of pronotum rectangular. Forewing 3.5–4.0× longer than wide; concavity at costal border absent; Sc+R+M forming common stem (sometimes very short); r–m1 basad of or at same level as fork MA–MP; position of icu at CuP distad of apex of clavus; nine apical cells. Hind tibia with six apical teeth in a row interrupted by a wide gap; 1st tarsomere normally with 11 apical teeth and five platellae; 2nd tarsomere normally with 10 apical teeth and eight platellae. Male genitalia. Aedeagus with a similar configuration of spines in all species. (Löcker et al. 2006)
