This species was recognized and described by Dr Andrew C. Keth (2002) in his unpublished PhD dissertation based on specimens from Venezuela. We contacted Dr Keth and he authorized us to include his description of this species in our publication. Figures 6A–6D View FIGURE 6 were prepared from our specimens from Brazil (Pará State).
Diagnosis. The presence of the following characters clearly places this species in the Neotrichia aserradera Group: 1) serrate, rectangular inferior appendages, 2) long, sclerotized phallus spikes, and 3) highly reduced tenth segment. This species is similar to N. aserradera but is diagnosable using the following combination of characters: 1) segment VIII lacking apicodorsal setal lobes, 2) inferior appendage lacking dorsal projection, and 3) segment X distinct from, but not projecting beyond segment IX. Although one or more of these individual characters may occur in other Neotrichia species , Neotrichia flinti is the only species to exhibit the unique combination of all of these characters.” ( Keth 2002)
Description. Male: Length 1.7–2.0 mm. 18 antennal segments. Brown in alcohol.Abdominal segments VII and VIII annular. Segment IX arising from within segments VII and VIII, anterior margin angular, producing a long, slender, finger-like extension; posterior margin rounded, sclerotized. Segment X fused with dorsum of segment IX, short, uniform, and nearly blunt with only slight dorsoapical angularity in lateral view; in dorsal view covered with field of stout setae, narrow and uniform to emarginate apex producing slight, rounded lobes from apicolateral comers.” ( Keth 2002)
Male Genitalia. Subgenital plate tapered and slightly curved to acute, rounded apex with short, tongue-like extension in lateral view; in ventral view nearly uniform to mesally-rounded apex with lobate apicolateral comers producing paired setae. Inferior appendage nearly rectangular and slightly sclerous with rounded apex appearing somewhat bilobed in lateral view; in ventral view tapered with rounded margins, apex hooked slightly mesad and appearing somewhat claw-like with multiple rows of stout setal serrations along mesal margins. Bracteoles basally slender, broadened to blunt, spatulate apex in lateral view; in ventral view short, slender and slightly tapered to acute, rounded apices. Phallus long and narrow with preapical constriction giving rise to slender, round paramere; apex long, slender, and finger-like with paired sclerotized rods along ventral surface; one rod nearly equal in length to phallus apex, other rod 14 that length and hooked sharply dorsad at extreme tip; ejaculatory duct uniform to phallus tip, non-protruding.” ( Keth 2002)
