Dolophilus breviatus Banks 1914: 254   , pl. XX, fig. 61, male, New York, USA (Banks, N. collection, MCZ); Betten 1934: 168, 169, pl. 15, figs. 13, 14, pl. 16, figs. 1–5; Milne 1934 –1936: 82, 83 (as synonym of D. moestus   ); Ross 1938c: 7 (lectotype [ MCZ 11518 View Materials ] is male, mentioned as D. breviatus   ); Ross 1944: 292 (as D. moestus   ); Ross 1949: 154–156 ( D. moestus   transferred to Wormaldia   ).

Ross (1949) established subgroup 2 of the W. moesta   Group with W. moesta ( Banks 1914)   and W. gabriella ( Banks 1930)   , species from Canada and the Uniteds States. In 1956, Ross rearranged his former species group proposal. For the W. moesta   Group, he removed subgroup 2 and to the two species formerly mentioned added two species W. chinensis ( Ulmer 1932)   from China and W. relicta ( Martynov 1935)   from India. Later, Schmid (1991, 1998) suggested that all former species, with the exception of W. moesta   , should be placed together within the W. relicta   Group instead of Ross’s W. moesta   Group. Schmid also added to the W. relicta   Group the four following species: W. ephestion Schmid (1991)   and W. therapion Schmid (1991)   from India, W. simulans Kimmins (1955b)   from Burma, and W. uonumana Kobayashi (1980)   from Japan. He adopted this change since W. moesta   only has one character among those that define the species group. However, Schmid recognized that the characters that define the W. relicta   Group are not constant in the seven species of his W. relicta   Group ( Schmid 1991). Armitage (1996) maintained the Ross proposal for this species group (Table 1).

This species is similar to Wormaldia gabriella ( Banks 1914)   and W. lacerna Denning (1958)   , but can be recognized from them by the shapes of tergum VIII, sterna VIII and IX, and the inferior appendage, as discussed in the diagnoses of those species. Wormaldia moesta   specimens from Little Pigeon (Tennessee) and Turkey Run S.P., Newby Gulch (Indiana) showed variation in the shape of the posterior margin of tergum VIII from that of the holotype. The posterior margin in those specimens is relatively straight mesally or straight with a small, narrow emargination mesally ( Figs. 72–73).

Adult ( Fig. 133) Length of male forewing 6–7 mm. Head brown, with yellowish setae. Antenna long, slender, yellowish, with small, yellowish and brown rings of small setae. Maxillary palps yellowish, with lighter setae. Labial palps yellowish, with lighter setae. Dorsum of thorax light brown. Legs yellowish, with small, lighter setae. Forewing yellowish, covered with fine, small, brown setae, and with several small, scarce patches of yellowish setae, one conspicuous, mesal patch, slightly elongate anteroposteriorly on posterior margin, with apical forks I, II, III, IV, and V present ( Fig. 74; Betten 1934: pl. 15. fig. 13). Hind wing translucent, with very few fine, small, brown setae, with apical forks I, II, III, and V present ( Fig. 75; Betten 1934: pl. 15, fig. 14).

Male genitalia ( Figs. 67–73). Sternum VII with stout, prominent, digitate, posteromesal process extremely elongate, longer than sternum VIII, narrowly rounded apically. Tergum VIII slightly sinuous or nearly straight posteromesally; when viewed laterally, slightly concave posteriorly. Sternum VIII slightly concave anteriorly, with conspicuous, digitate, posteromesal process, 0.5 times length of posteromesal process of sternum VII, rounded apically. Segment IX, when viewed dorsally, concave anteriorly; when viewed laterally, broad, nearly rectangular in appearance, slightly convex anteriorly, slightly convex posteriorly; when viewed ventrally, concave anteriorly, nearly straight posteriorly with small, slender, subtriangular process arising posteromesally. Segment X, when viewed dorsally, triangularly elongate, very weakly bulged medially, narrowest and rounded apically; when viewed laterally, stout, rounded apically. Superior appendages digitate; when viewed dorsally, parallel with segment X, stout, elongate, rounded apically; when viewed laterally, shorter than segment X, slightly enlarged basally, rounded apically. Inferior appendages two segmented; when viewed laterally, basal segment thick, subrectangular, weakly elongate, broadest and convex medially, apical segment stout, rectangularly elongate, nearly equal in length, narrower than basal segment, and truncately rounded and narrowest posteriorly; when viewed dorsally, apical segment stout, subtriangularly elongate, narrowest and subovate posteriorly, with slightly elongate and apicolateral patch of short, thin, black, spine-shaped setae; when viewed ventrally, basal segments paired, united for about their anterior three-quarters, separated posteromesally by a moderately deep and U-shaped emargination, each basal segment stout, widest medially, with outer margin convexly curved, apical segment as when viewed dorsally. Phallus, when viewed laterally, pistol-shaped, widest basally, tapering from middle to apex, membranous apically, very lightly sclerotized, when viewed dorsally, with many visible, small, spine-shaped, internal sclerites ( Fig. 71), surrounded by highly convulated membranes.
