No full textNeozygina expanda n. sp. (Figs. 1V, 4J–K) Diagnosis. Length of male 2.6 mm, female 3.1 mm. Closely resembling N. argentiniensis, but differing as follows: pygofer with dorsal appendage extended to apex; aedeagal shaft (Figs. 4J, K) in lateral view more strongly divergent from dorsal apodeme and with posterior margin evenly curved, processes formed by bifid apex strongly expanded and convergent distally. Material examined. Holotype male, ARGENTINA: La Rioja, Dept. Famatina, 10 km N Famatina, Hwy. 40, Sierra de Toro Negro, 4,450ft., 28.9591°S, 67.4705°W, 15/ 20 October 1997 (M.E. Irwin, F. D. Parker, S. Roig, Malaise trap, MEI 97-35) [INHS]. Paratype, 1 female, same data [INHS]. Note. The specific name refers to the expanded aedeagal apex, which distinguishes this species from other South American Neozygina.Published as part of Dietrich, C. H. & Dmitriev, D.

No full textNeozygina potosiensis n. sp. (Figs. 1N, 3O–Q) Diagnosis. Length of male 2.8 mm. Coloration as described for N. mandibulata. Male pygofer (Fig. 3O) with dorsal appendage large, resembling that of N. hondurensis, but not extended to pygofer apex; ventral appendage arising at apex, relatively short, slender, extended posteromesad; lobe between appendages concave, weakly sclerotized.

Neozygina obsoleta Dietrich & Dmitriev 2007, n. sp.
No full textNeozygina obsoleta n. sp. (Figs. 1M, 3M–N) Diagnosis. Length of male 3.1 mm (approximate; forewings of holotype missing). Coloration and markings as in N. chiapensis. Pygofer (Fig. 3M) with dorsal appendage obsolete, reduced to heavily sclerotized ridge that extends half distance to apex; ventral appendage arising near apex, short, slender, extended posterad the abruptly bent dorsad; distal lobe narrow, weakly sclerotized dorsally. Aedeagus (Fig. 3N) with preatrium short; shaft in lateral view relatively broad and compressed basally with small dorsal teeth, gradually narrowed to midlength, distal half slender, tubular, strongly arcuate, with slender unpaired ventral preapical process; gonopore apical; apex with large unpaired distal spine extended ventrad. Material examined. Holotype male, MEXICO: Guerrero, Iguala, 11 September 1939 (D. M. DeLong) [INHS]. Notes. Placement of this species in Neozygina, despite the absence of a dorsal appendage on the male pygofer, is justified by the presence of macrosetae on the dorsal margin of the pygofer and by the coloration, which is indistinguishable from that of many other members of the genus. The aedeagus is unique among known species of the genus in having upaired apical and preapical posterior spines. The specific name refers to the obsolete dorsal pygofer appendage.Published as part of Dietrich, C. H. & Dmitriev, D.

Neozygina Dietrich & Dmitriev 2006
No full textNeozygina Dietrich & Dmitriev, 2006 Diagnosis. Crown weakly to moderately produced medially, with pair of large brown or black preapical spots; mesonotum with basal triangles usually dark brown, contrasting with remainder of sclerite; forewing lacking distinct spots or oblique patterns, inner apical cell with base oblique; male pygofer with dorsal appendage well developed (except N. obsoleta, n. sp.), immovably fused to pygofer margin; one or more macrosetae present basad of dorsal appendage; ventral appendage present, usually elongate. Style apex truncate, footlike, with only two points, preapical lobe well developed. Connective U-shaped, without median anterior lobe, arms short. Aedeagus with dorsal apodeme well developed, usually T-shaped in posterior view, without sclerotized connection to dorsal pygofer appendage or anal tube; shaft often with paired or unpaired basal or distal processes, or both; unpaired basal process, when present, closely appressed to shaft. Distribution. Western United States south to Argentina. Notes. Phylogenetic analysis of morphological data recovered Neozygina as the monophyletic sister group to a clade comprising the New World genera Mexigina, Hepzygina, and Zyginama (Dietrich & Dmitriev 2006). The genus previously included 10 described species, 1 of which is here treated as a junior synonym. An additional 16 species discovered during this study are described below. The following key will separate adult males; females of most species may only be reliably identified through their association with males.Published as part of Dietrich, C. H. & Dmitriev, D.

Erasmoneura latiloba Dmitriev 2008, sp. n.
No full textErasmoneura latiloba sp. n. (Figs. 2, 3) Description: Body size (male, female): 2.4–2.5 mm. Coloration (male, female): Dorsum entirely reddish brownish, without color pattern. Anteclypeus dark brown. Thoracic venter entirely dark brown. Head (male, female): Crown fore margin strongly produced and angulate medially. Abdomen (male): 2S abdominal apodemes large, broad, reaching 3S posterior margin. Genitalia (male): Pygofer lobe rounded; dorsal appendage with distinct basal suture, but not movably articulated, simple, not extended beyond pygofer apex, straight in dorsal view, curved downward in lateral view. Style apex threepointed, second point very short, tooth like; third point elongate, about as long or longer than distance between other two points; angle between basal and third points less than 90°. Aedeagus with preatrium longer than shaft; shaft curved ventrally, broad in lateral view; depressed in crossection, with large lateral lobes, with small dorsal distal lobe; ventral processes absent; distal processes long, apical, slender. Type locality: Holotype ♂, USA, South Carolina, Aiken Co., Aiken, 12 V 1957 (J. R.U.), (CNC). Studied material: Paratypes: 3 ♂, 7 ♀, same data as holotype, (CNC); 1♂, 1♀, same data, (INHS). Host plant: Unknown. Note: The species name refers to the broad lobes on the sides of the aedeagal shaft. Like E. rubricata Van Duzee and E. margaritae Dmitriev & Dietrich, this species has a broad and depressed aedeagal shaft. It differs in longer distal processes of the aedeagus and smaller size.Published as part of Dmitriev, D.
