Generic synopsis of the jumping plant-lice (Hemiptera: Sternorrhyncha: Psylloidea) from Colombia Author Rendón-Mera, Diana Isabel Author Serna, Francisco Author Burckhardt, Daniel text Zootaxa 2017 2017-11-20 4350 3 journal volume 31376 10.11646/zootaxa.4350.3.2 c5176d49-ee06-4e6e-946c-7895b400b5ea 1175-5326 1059233 42EC36DB-84AD-44DF-ADA4-978DA50CDA46 Gyropsylla Brèthes ( Figs 10 , 77 ) Diagnosis: Head about as wide as mesoscutum; vertex about 1.75 times wider than long; genae not forming processes, but expanded as a lobe-like swelling between antennae and eyes; frons forming elliptical/elongate sclerite, closed below the genae. Clypeus tubular, extended perpendicularly to lower head surface, with shoulderlike constriction medially ( Fig. 10 , arrow). Antenna longer than head width; both terminal setae truncate, one approximately 3 times the length of the other. Forewing with costal break; pterostigma from short and broad to long and very narrow. Veins R and M+Cu1 subequal, vein M moderately curved; cell cu1 much larger than m1. Hind leg with small meracanthus; area beneath meracanthus forming a rounded swelling ( Fig. 39 ); metafemur apically and metatibia basally with a group of long stout bristles ( Fig. 40 ); metatibia without genual spine, with a dense crown of about 10 apical spurs; metabasitarsus with two apical spurs. Biology and damage: Immatures feeding on young shoots and leaves on which they induce blister-shaped galls. Immatures are covered in waxy secretions and produce lots of honeydew ( Brèthes 1921 ; Iede & Machado 1989 ; Leite & Zanol 2001 ). Host-plants: Ilex (Aquifoliaceae) ( Hodkinson 1989 ; Burckhardt & Queiroz 2013). Distribution: Neotropic, Neartic and Oriental regions (Burckhardt & Queiroz 2013). Examined material: Gyropsylla sp.: Nariño : 15 (female) Pasto , Obonuco , Feb-1985 , potato ( N. Ruiz ), CTNI 59 .
