Parallaxis misionensis

description: Parallaxis misionensis sp. n.
(Figs 1 B, 3A–G)
Description. Length of male: 3.0– 3.1 mm.
Ground color whitish with red marks. Crown white to yellowish with two small red spots on hind margin. Pronotum with two longitudinal red bands. Forewing whitish with three elongated red spots, two in claval area and one in brachial cell; costal margin orange-reddish, apical cell smoky (Fig. 1 B). Fore and hind wing venation characteristic of genus.
Male: Second sternal apodemes (2S) (Fig. 3 A) reaching midlength of fourth segment, apices obliquely truncated. Pygofer (Fig. 3 B) rounded in lateral view, with a dorso-apical lobe slightly sclerotized, vertical row of six or seven macrosetae near caudal margin, several microsetae on disk. Subgenital plate (Fig. 3 C) with nearly parallel margins, oblique single row of four macrosetae over basal half of disk, and several microsetae in dorsal and ventral margin. Style (Fig. 3 D) with rounded preapical lobe; apical extension short and curved, apex bilobed. Connective (Fig. 3 E) U-shaped. Aedeagus (Figs 3 F–G) with long preatrium; barlike dorsal apodeme; shaft asymmetrical compressed, with a single subapical ventral process extending dorso-cephalad, and single apical process curved ventro-cephalad, apex acuminate extended dorsally; gonopore subapical.
Female: Unknown.
Material examined: Holotype male: ARGENTINA: Misiones, P.N. Iguazú, 25°49´43’’S 54°26´58´´W, 6–7 January 2008, C.H. Dietrich et al., Malaise trap [MLP]. Paratypes: 4 males, same data [INHS].
Etymology: The specific name refers to the province where the holotype was collected.
Notes: This species is easily distinguished from other species by the processes of the aedeagus.
Parallaxis tucumanensis sp. n. (Figs 1 C, 4A–K)
Description. Length of male: 2.9–3.0 mm; female: 3.0– 3.1 mm.
Ground color yellowish brown. Crown and pronotum yellow with irregular light brown spots, coronal suture dark. Scutellum yellow. Forewing greenish yellow, apex smoky with transparent roundish spots at base of apical cells and at apex of discal cells; claval area with brownish areas tessellated with small round whitish spots (Fig. 1 C). Fore and hind wing venation characteristic of genus.
Male: Second sternal apodemes (2S) (Fig. 4 A) long, reaching posterior margin of fourth segment. Pygofer (Fig. 4 B) quadrangular in lateral view, posterior margin with strong falcate spine on upper corner and short fingerlike lobe with irregular denticuli posteroventrally, 4–5 macrosetae on dorsal caudal margin and several microsetae on caudal margin. Subgenital plate (Fig. 4 C) with base wider than apex, apex curved dorsally, oblique single row of 5–6 macrosetae over basal half and several microsetae in apical half. Style (Fig. 4 D) with small preapical lobe with group of 4–5 small setae on margin; apical extension elongate and nearly straight. Connective (Fig. 4 E) U-shaped. Aedeagus (Figs 4 F–G) with short preatrium; barlike dorsal apodeme; shaft with pair of subapical dorsal processes curved cephalo-ventrad in lateral view, single apical process curved caudo-ventrad, and a subapical tooth on dorsal margin; gonopore subapical.
Female: Sternite VII (Fig. 4 H) rounded with several microsetae on disk. Pygofer (Fig. 4 I), in lateral view, oval with 12 macrosetae in row on caudo-ventral margin. Second valvulae slender, large valve (Fig. 4 J) with 14–16 strong teeth irregularly denticulate, ventral margin with 7–8 small teeth, with three sclerotized longitudinal bars, ramified apically, on lateral surface; small valve (Fig. 4 K) without teeth on apex, and three sclerotized longitudinal bars on lateral surface.
Material examined: Holotype male: ARGENTINA: Tucumán, Los Planchones, 26º36’ 04.32S 65º25’ 11.49W, 30–31 March 2010, E. Virla, Malaise trap. [MLP]. Paratypes 3 males and 3 females: ARGENTINA: Tucumán, Los Planchones, 16–19 April 2010 and 8–11 April 2011, E. Virla, Malaise trap. [2 males and 2 females in INHS] [1 male and 1 female in IML].
Etymology: The specific name refers to the province where the holotype was collected. Notes: This species closely resembles P. donaldsoni Baker, but has the apical processes of the aedeagus longer, shifted basad and oriented differently in posteroventral view.
