Length. Body: 14 mm; wing: 9.5 mm.
Holotype condition. Complete. Terminalia dissected and placed in microvial with glycerine, pinned with the specimen.

Similar to male (Fig. 21), except second article of stylus without a distinct ventral projection at base, only with a slight projection ventrally, remainder of stylus laterally compressed (Fig. 22A); terminalia shining, dark reddish black; T 8, S8, and cercus with sparse, thin, yellowish setae (Fig. 22B–D); two spermathecae (Fig. 22E–F) reaching T 6 and T 7 (Fig. 22E–F); spermathecal ducts ending separately at genital fork (Fig. 22G–H); apodeme of genital fork approximately 1/5 of the length of lateral sclerites (Fig. 22F), conical proximally and with a slight concave indentation distally (Fig. 22G), in lateral view with a dorsal keel resembling a Portuguese man o’ war (Fig. 22H); medial sclerite present (Fig. 22F).
Variation. Mystacal macrosetae with 4 lateral dark brown macrosetae; orbital setae black; ocellar tubercle with 1 pair of setae; scape with ventral black setae mixed with other whitish setae; subvibrissal setae black; palpal setae dark brown to black; some dark brown occipital setae mixed with the whitish setae; postocular setae with inner macrosetae dark brown; scutellum with short, black discal setae; legs dark reddish; abdomen dark brown and grey pruinose; hypandrium with 5–6 black macrosetae at posterior margin laterally to mid-posterior projection; midposterior hypandrial projection with black setae mixed with white setae at posterior margin.
Etymology. platylobus, from Greek: platys: meaning broad, wide or flat; and lobos: elongate projection or protuberance, capsule or pod. The name makes an allusion to the rounded, laterally compressed lobe projecting at the ventral base of the second article of the stylus.
Distribution. Brazil (Mato Grosso and Mato Grosso do Sul) (Fig. 23).
