Lepidura patagonica Araujo & Vivallo , sp. nov.

( Figs. 4 View FIGURE 4 , 9, 10 View FIGURES 9–12 )

Diagnosis: White pubescence covering entire body, denser on head, most of mesosoma and ovipositor sheath, sparser on metapleuron and most of metasoma. Head turquoise green, with antenna dark brown, mandible yellow with well developed, dark brown teeth ( Fig. 9 View FIGURES 9–12 ). Body turquoise green, except mesoscutum, mesothorax, anterior and posterior margins of T2, anterior margin of T3 and T6–9, dark brown. Posterior margins of T3–5 light brown. Legs turquoise green; anterior margin of femur, anterior and posterior margins of all tibiae and tarsi brown ( Fig. 10 View FIGURES 9–12 ).

Description. Holotype female ( Figs. 9, 10 View FIGURES 9–12 ). Approximate body length: 11.0 mm. Fore wing length: 7.3 mm; antenna length: 5.5 mm; number of flagellomeres: 40–42; head 1.15× as wide as high (front view); distance between eye and lateral ocellus 1.00× as long as diameter of lateral ocellus; frons smooth,; clypeus 0.50× as wide as high; mandible 3.10× as long as basal width (front view); mandible with two well developed teeth; mandible basal width 1.90× as long as malar space; pronotum polished; hind femur 11.05× as long as wide; hind tibia 9.25× as long as wide; hind basitarsus 14.10× as long as wide; mesosoma generally smooth, polished and finely punctate; areolet large, rhombic, 1.50× as wide as long; hind wing with 5 hamuli; propodeum smooth, with isolated punctures; areola absent, but with subpentagonal area delimited by complete lateral longitudinal and posterior transverse carina and incomplete anterior transverse and median longitudinal carina ( Fig. 1 View FIGURES 1–3 ); postpetiole 1.80× as long as maximum width; glymma deep, seemingly with thin membrane between both sides; T1–T7 smooth, with isolated punctures; T2 4.85× as long as its height (lateral view); hypopygium large and triangular in lateral view ventral extremity weakly scletorized, 2.00× as long as wide; ovipositor sheath, 1.50× as long as basal width.

Male: Unknown.

Type material: Holotype female: Argentina, Neuquén, Villa La Angostura , 22-II-2 0 14, Martinez, Compagnucci, Ojanguren, Piacentini col. ( MACN). 5 paratypes females with the same label information.

Type locality: ARGENTINA: Neuquén: Villa La Angostura .

Distribution ( Fig. 4 View FIGURE 4 ): ARGENTINA: Neuquén: Villa La Angostura.

Etymology: The species is named after the region of the type locality.

Comentário: Lepidura patagonica sp. nov. is similar to L. viridis by the absence of vein CU/1b on the hind wing and the lentgh of the T2, 2.50× its width or longer. The two species can be differentiated by the presence of the costula and the anterior transverse carina of propodeum, absent in L. viridis . There was no variation between the specimens, this is the larger species in the genus.
