Katacephala Crawford 

( Figs 20View FIGURES 10 – 27, 52View FIGURES 47 – 58, 80View FIGURES 77 – 80)

Diagnosis: Head and thorax covered in conspicuous setae; vertex large, convex; genal cones often indistinctly separated from vertex, often stout and contiguous along inner margin ( Fig. 20View FIGURES 10 – 27); occipital sclerite as a strip, giving the eyes a stalked appearance; lateral ocelli raised on tubercles. Antennae not markedly longer than 1.5 times the head width; segment 3 the longest. Forewing rhomboidal or with narrowly rounded apex; with costal break and pterostigma; wing membrane from hyaline to somewhat coriaceous; veins bearing long conspicuous setae; vein M+Cu1 short relative to Cu1 ( Fig. 52View FIGURES 47 – 58). Meracanthus short; metatibia without genual spine; with a crown of 6–8 apical spurs; metabasitarsus with 2 apical spurs. Male proctiger with a well-developed angular posterior lobe.

Biology and damage: Immatures of Katacephala tenuipennis Tuthill  excrete waxy secretions in which they are covered. They cause the edges of leaves to curl down and inward to form a closed linear pocket where they live and develop ( Mead 1990).

Host-plants: Myrtaceae  and Asteraceae  ( Hodkinson 1991; Burckhardt 1994a).

Distribution: Southern United States, Central and South America ( Hodkinson 1989).

Remarks: This is the first record of this genus in Colombia.

Examined material: Katacephala  sp.: Cundinamarca: 1 (female), Zipaquirá, Vda. El Empalizado, Fca. La Niña María  , 5°5'16"N, 74°3'11"W, 3200 m, 19-Sep-2012, on grass (M. Echeverry), UNAB 1493.
