Length 1.4–1.9 mm. Head dark brown with silver-gold microtomentum on lunule, interfrontal plates, ocellar triangle, orbital plates, and occiput; gena caramel-brown; antenna brown. Frontal width 2.5× interfrontal height. Eye height 2.5× genal height. Thorax dark brown, anepimeron with a pale ventral spot. Scutum with pale grey and brown microtomentum forming indistinct dark longitudinal stripes, lateral margins broadly pale yellow microtomentose, pale M-shaped microtomentose mark at level of posterior dorsocentral bristles; scutellum dark brown with median, grey-brown microtomentose triangle. Anterior dorsocentral bristles separated by 7–8 rows of acrostichal setulae. Legs dark brown, femora apically and tibiae proximally paler, tarsi pale brown. Male mid tibia with a stout apicoventral bristle and two rows of stout ventral setae. Wing (Fig. 40G) pattern strong. CS2 0.5× CS3. R 2+3 almost straight for most of its length, distal quarter abruptly bent towards costa, causing R 2+3 to reach costa at a ~60° angle and moderately separated from costa for most of its length; costa extending very slightly beyond apex of R 4+5 (1–2 × costal width). M 1 and M 4 both extended slightly beyond dm-m; CuA+CuP long and tubular. Halter white. MALE ABDOMEN (Fig. 18). S5 narrow, posteromedially desclerotized with long posterolateral setae. S6 short and broadened. Cercus small, flat with a very large seta and two smaller setae, mesial edges touching each other; subepandrial sclerite broadly pentagonal and medially darkened. Surstylus large, bilobed: anterior lobe low, triangular with several ventral setae, posterior lobe large, rectangular, apically setulose. Postgonite elongate with a long, triangular lateral fin and a strong, triangular posterior extension. Phallapodeme relatively short, stout with a broad, arrow-like apical part; basiphallus narrow but long and box-like with an elongate, flattened and apically setulose epiphallus. Distiphallus stout: basal part well sclerotized and tubular, with a well-developed dorsal sclerite and separate, apically bifurcate lateral sclerites; apical part with large membranous flaps and supported by basal part. FEMALE ABDOMEN (Fig. 19). T6 semicircular, well-developed, and long-setose along posterior margin; T7 well-developed, rectangular and long-setose along posterior margin; T8 large, slightly emarginate posteromedially with long setae in posterolateral margins. Epiproct largely reduced. S6 and S7 well-developed and rectangular; S8 large, semicircular, and uniformly long-setose, posterior edge with a broad desclerotized margin. Hypoproct semicircular, with sclerotized anterolateral edges and a membranous, setulose medial part. Spermathecae stout, spherical, and smooth, stem short and sclerotized. Remarks Parapterogramma magnum is externally most similar to Pa. gonitellum sp. nov., from which it differs in having a broader frons (width 2.5× height), straighter R 2+3, long and tubular CuA+CuP, and the costa only extending 1–2 costal widths beyond R 4+5.
