Pelocnistis is a genus of moth in the family Gelechiidae. It contains the species Pelocnistis xylozona, which is found in Brazil. The wingspan is about 9 mm. The forewings are light greyish-ochreous irrorated dark grey and with an obscure rather narrow direct median fascia of brownish and dark grey sutfusion, a dark grey dot on this indicating the plical stigma.
