Dasyhelea monticola Ingram and Macfie, 1931: 188   (male, female, Chile); Wirth, 1974: 17 (in catalogue of south USA species); Borkent and Wirth, 1997: 56 (in World catalogue); Borkent and Spinelli, 2000: 25 (in New World catalogue south of the USA); Borkent and Spinelli, 2007: 60 (in Neotropical catalogue); Borkent, 2017: 67 (in online World catalogue).

Diagnosis

Only species of Dasyhelea   in Patagonia with the following combination of characters: male paramere J-shaped. Female subgenital plate circular; cubital fork of wing distad to level of end of costa; spermatheca ovoid with oblique neck.

Redescription of male. Similar to female with usual sexual differences. Antennal flagellum as in Figure 7A View Figure 7 . Palpus ( Figure 7B View Figure 7 ) brown; segment 3 bearing scattered sensilla on basomesal surface; PR 3.57–4.66 (4.14, n = 10). Scutellum with 7–8 large, 1–2 thinner setae. Wing ( Figure 19B View Figure 19 ) length 0.69–1.14 (0.94, n = 10) mm, width 0.24–0.36 (0.31, n = 10) mm; CR 0.38–0.44 (0.41, n = 10). Genitalia ( Figure 7C View Figure 7 ): tergite 9 rounded distally, reaching level of apex of gonocoxites, apicolateral process moderately short, stout, with conspicuous apical seta; cercus very small with 2–3 small setae; sternite 9 ( Figure 7D View Figure 7 ) 0.5 length of greatest width, posteromedian projection rounded, reaching one-third of aedeagus length. Gonocoxite stout, 1.8 × longer than greatest width, with short, blunt anteromedian process; gonostylus 0.9 length of gonocoxite, base moderately broad, slightly curved, tapering slightly distally, apex barely hooked, tip pointed. Paramere and gonocoxal apodemes ( Figure 7E View Figure 7 ) forming an asymmetrical structure; gonocoxal apodemes stout, right apodeme barely fused with paramere, left broadly fused with paramere; paramere greatly elongate, J-shaped. Aedeagus 0.9 length of greatest width, W/L ratio 0.50–0.60 (0.53, n = 7); anterior margin concave; basal arms heavily sclerotized, stout, recurved 60°, posteriorly directed; posterolateral arms stout, straight, parallel, tapering to slender, sharply pointed tips, each with mesal, subapical, outer triangular process; posteromedian projection short, slender, triangular, tapering distally, with simple, pointed tip.

Redescription of female. Head dark brown. Eyes contiguous for distance of the width of 3 ommatidia. Antennal flagellum ( Figure 7F View Figure 7 ) pale; AR 0.85–1.03 (0.91, n = 10). Clypeus ( Figure 7G View Figure 7 ) with 4 pairs of setae. Palpus ( Figure 7H View Figure 7 ) pale brown; segment 3 with 2–3 subbasomesal capitate sensilla; PR. 3.20–4.00 (3.60, n = 10).

Thorax. Scutum dark brown, scutellum pale brown with 6–7 large, 2–3 thinner setae; apex of hind tibia with 4–6 spines; foreleg TR 1.59–2.03 (1.70, n = 10), midleg TR 1.67–2.02 (1.82, n = 10), hind leg TR 1.77–2.00 (1.87, n = 10). Wing ( Figure 19A View Figure 19 ) length 0.75–0.96 (0.85, n = 10) mm, width 0.30–0.42 (0.37, n = 10) mm; CR 0.30–0.44 (0.39, n = 10); membrane slightly infuscated, densely covered with macrotrichia; radial cells obliterated; cubital fork slightly distad to level of apex of costa. Haltere dark brown, knob base whitish.

Abdomen. Pale brown. Subgenital plate ( Figure 7I View Figure 7 ) circular with narrow lumen, without posteromedian projection; posterolateral arms moderately broad, distal portions slender, recurved nearly 90°. Spermatheca ( Figure 7J View Figure 7 ) ovoid heavily sclerotized, 60 × 36 µm, neck oblique, short, measuring 12 µm.

Phylogenetic relationships

Dasyhelea monticola   is the sister species of D. suarezi Spinelli and Ronderos. The   clade ( D. monticola   , D. suarezi   ) is suppoted by the characters “parameres” [character 13 (1)]; “shape of posteromedian projection of aedeagus” [character 19 (2)] and “cubital fork (female)” [character 23 (1)].
