Parapolynema tucumanum Fidalgo 1991: 153. Type locality: Aconquija National Park [as Parque Aconquija on the original label], Tucumán, Argentina. Subsequent references: Loiácono et al. 2005: 15 (holotype information); Luft Albarracin et al. 2009: 11 (list); Luft Albarracin et al. 2014: 137 (list).
Type material examined. Holotype female [MLPA (Fig. 37)] on slide (Fig. 36), as listed in Fidalgo (1991, p. 153) and Loiácono et al. (2005, p. 15).
Additional material examined. ARGENTINA. La Rioja: Anillaco: 1–31.iii.2001, P. Fidalgo, J. Torréns, G. Fidalgo [3 ♀, UCRC]; 1–30.iv.2001, P. Fidalgo, G. Fidalgo [1 ♀, UCRC]. Santa Vera Cruz, 28°40’42.7’’S 66°57’50.4’’W, 1660 m, P. Fidalgo: 6.xi–5.xii.2001 [1 ♀, UCRC]; 15.vii–15.viii.2002 [1 ♀, UCRC]; 1–15.xii.2002 [1 ♀, UCRC]; 31.xii.2002 [1 ♀, UCRC].
Diagnosis. In addition to the features mentioned in the key, females of C. tucumanum differ from those of all other mainland South American species of Cremnomymar by the peculiar maculation of the fore wing (Fig. 41).
Redescription (holotype and non-type specimens from La Rioja). FEMALE. Body length (dry-mounted specimens, as in Fig. 38) 730–860 µm. Body (Fig. 38) and appendages light brown or brown except often scape and metacoxa a little darker. Head (Fig. 39) wider than high; face with fine, inconspicuous mesh-like sculpture above toruli. Antenna (Fig. 40) with scape, excluding short radicle (not fused with the rest of scape), 3.5–3.8× as long as wide; pedicel almost as long as F2 and longer than any other funicle segment and 1.7–1.8× as long as wide; all funicle segments short, F1 the shortest and F2 the longest, F6 the widest and without mps; clava 2.5–2.9× as long as wide, longer than combined length of the 3 preceding segments, with all mps in apical half. Mesosoma about 1.7× as long as wide; pronotum, mesoscutum, scutellum and frenum with reticulate mesh-like sculpture; mesoscutum wider than long, with notauli more or less distinct and complete; scutellum about as long as mesoscutum; propodeum mostly smooth, with a complete median carina. Fore wing (Fig. 41) 3.4–3.6× as long as wide; venation with an apical process about as long as marginal + stigmal vein; disc with 2 narrow transverse bands beyond venation, the proximal band either about as wide or a little narrower than the distal band, densely setose beyond venation, with discal setae modified on the dark bands; most of fringe setae on anterior margin thickened, the basal ones short and subapical ones long while apical ones more or less normal; the longest marginal seta 0.8–1.0× greatest width of wing. Hind wing (Fig. 41) 37–41× as long as wide, with disc mostly hyaline except slightly infumate medially and sparsely setose beyond venation, the longest marginal seta 9–10× greatest width of wing. Metacoxa smooth. Petiole cylindrical, with wrinkles dorsally. Ovipositor 0.7–0.8 length of gaster, not exserted beyond gastral apex, and about 0.9× length of metatibia.
MALE. Unknown.
Distribution. Argentina: La Rioja [new record], and Tucumán (Fidalgo 1991).
