%X Se presenta el an¨¢lisis filogen¨¦tico para 18 especies conocidas de Zeugmatothrips, usando el m¨¦todo del grupo externo. Cuando se incluy¨® al g¨¦nero Cyphothrips en el grupo interno, se obtuvieron novedosos resultados de un posible grupo no monofil¨¦tico y nueve ¨¢rboles con un c.i.= 0.594, h.i.=0.493, longitud=69 y un g=0.46 (p>0.01). El ¨¢rbol de consenso estricto tiene un c.i. (Rohlf) =0.938. Las politom¨ªas se resolvieron utilizando el an¨¢lisis de Dm¨¢x (equiprobabilidad). Se repiti¨® el an¨¢lisis usando un ancestro hipot¨¦tico, la longitud se increment¨® pero el c.i. para el consenso fue similar This paper presents a phylogenetic analysis of the 18 known species of Zeugmatothrips. The analysis is rooted using the outgroup method. When the genus Cyphothrips was included in the ingroup, novelties results in a possible non-monophyletic group was obtained. Nine trees were obtained with c.i.= 0.594, h.i.=0.493, length=69 and g=0.46 (p>0.01). The strict consensus tree is has a c.i. (Rohlf) =0.938. The politomies was resolved using the Dm¨¢x analysis. The analysis was repeated using an hypothetical ancestor, the length increase but the c.i. for the consensus was similar
