Diagnosis. Neotrichia serratais a member of the canixa group of Keth et al. (2015)based on the posterior horns from tergum X, forked bracteoles, bifid inferior appendages, and the forked phallic apex. The new species is most similar to N. canixa, N. unamas,and N. xicana, on the basis of the apicolateral processes from segment IX. It is most easily separated from these species by the serrate structure of the rods from segment IX.
Male.Length 1.6 mm, 18 antennal segments, brown in alcohol. Abdominal segment VIII annular. Segment IX incomplete dorsolaterally with setal-bearing lobe; anteriorly rounded, posteriorly bearing elongate, thin process, which is serrate on dorsal margin; ventrally with deep mesal incision on posterior and anterior margins. Tergite X narrow, with pair of symmetrical, sclerotized horns distally, basally fused with segment IX; in lateral view distal horn long and thin. Subgenital plate in lateral view wide basally, tapering distally to acute, downturned apex; in ventral view narrow with pair of stout, lateral setae apically. Bracteoles slender and bifid, dorsal and ventral branches similar in length, each terminating in elongate seta. Inferior appendages thin and tapering distally; in ventral view bifid, outer processes wide basally, tapering distally to rounded apices which are turned inward, inner processes fused basally and narrow over length, shorter than outer processes. Phallus tubular, constricted at mid-length and bearing thin paramere encircling shaft, apex divided into pair of short curving processes, ejaculatory duct protruding apically. Female.Unknown.
