Diagnosis. Xiphocentron dactylum sp. nov. is particularly similar to Xiphocentron (S.) eurybrachium sp. nov. mainly by the shape of the preanal appendage (in lateral view, straight throughout length, apically wide). However, X. dactylum sp. nov. can be differentiated from its congener by the (1) shape of sternum IX in ventral view, elongate and about as wide basally as apically, subrectangular (trapezoid, conspicuously wider apically in X. eurybrachium sp. nov.), by (2) the posterior margin of sternum IX with wide shallow V-shaped incision (absent in X. eurybrachium sp. nov.) in ventral view. Description. Male: Forewing length 3.0 mm (n = 2). Color overall dark brown, forewing uniformly dark brown. Maxillary palp segment length formula (I = II = III)
