 Description. Male. Body length, 2.8–3 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus yellowish-brown; one lower genal and two upper genal setae. Thorax. Scutum dark brown, pleural sclerites brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with medial and posterior areas gray. Legs light brown, except foretibia and foretarsus, yellowish-brown. Forefemur with ventral row of four strong setae near apex. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus ratio, 4.3. Midtibia with one anterodorsal and one posterodorsal setae at basal third (Fig. 178). Hind femur swollen (height/length ratio, 0.41), with ventral row of five strong setae and many proximal thinner setae near base (Figs. 246–247). Hind tibia with one anterodorsal and four posterodorsal setae (Fig. 215). Wing. Costa 0.5 of the wing length, other wing features as for the genus. Halter white. Abdomen. Tergites dark brown, with lighter posterior band. Hypopygium light brown (Figs. 84–87). Epandrial medial process not bifurcated, large. Epandrial right posterior margin projected posteriorly, with subepandrial setulose process. Hypandrium left lobe large; right lobe narrow. Hypoproct with two setae. Phallus (Figs. 290–291). Basiphallus without dorsal process. Core plate flattened. Epiphallus with large scales, connected to right arm at the left of phallus. Ventral plate well developed, approximately twice the core plate length, with many folds near apex and dented at left lateral margin.   
 Female. Unknown.   
 Geographic distribution. Ecuatorian and Colombian Amazonia.   
 Etymology. The specific epithet ptychodrilus refers to the folds in the phallic ventral plate and is derived from the Greek roots ptychos (fold) and drilos (penis), and should be treated as a noun in apposition.   
 Comments. Neopleurophora ptychodrilus is very similar to N. manauara. They can be differentiated by the N. ptychodrilus longer epandrial medial process and phallic ventral plate and only two teeth at ventral plate apex.
