Diagnosis.

This species is distinguished from other congeners by the following combination of characters: Small to moderately small shore-flies, body length 1.55-2.10 mm. Head: Frons mostly yellowish to golden tan, especially outline of mesofrons and fronto-orbits, anterior portion immediately dorsad of antennae yellowish orange, microtomentum denser and whiter at base of fronto-orbital setae. Antenna yellow to yellowish orange; basal flagellomere slightly brownish dorsally. Face black but completely to mostly silvery white microtomentose, often with medial, darker stripe with microtomentum thinner, otherwise lacking prominent, vertical stripes; bearing 2 larger facial setae, dorsal seta at about midfacial height, dorsomesoclinate; ventral seta just dorsad of epistomal margin, slightly dorsoclinate; parafacial silvery to creamy white; gena very short. Gena-to-eye ratio 0.05-0.07. Thorax: Mesonotum uniformly tannish to golden tan microtomentose; presutural supra-alar seta well developed; pleural area very sparsely microtomentose, mostly dark brown, partially subshiny, contrasted with densely microtomentose mesonotum. Wing hyaline except for conspicuous darkened clouds over crossveins r-m and especially over dm-cu (Fig. 62); vein R2+3 with apex more abruptly curved toward costa; costal vein ratio 0.51-0.60; M vein ratio 0.59-0.65. Femora mostly black; forefemur with 4-5 stout, peg-like setae on apical third along posteroventral margin; tibiae mostly brownish black, apices yellow; tarsi yellow. Abdomen: Generally black, mostly subshiny to shiny, dorsum of tergites very sparsely and finely microtomentose, faintly whitish gray. Male terminalia (Figs 63-66): Epandrium in posterior view (Fig. 63) elongate, inverted U-shaped, dorsal arch narrow, becoming wider ventrally, ventral margin bearing loose cluster of longer setulae, in lateral view widest subventrally, ventral margin more narrowly rounded; cercus in posterior hemispherical, not fused with ventral margin of cercal cavity, with somewhat evenly scattered setulae, those toward ventral margin longer; gonite in lateral view (Fig. 66) somewhat rod-like, shallowly curved, both ends tapered, in ventral view (Fig. 65) knife-like, medial end blade-like, lateral extension narrow with apical portion curved and pointed; aedeagus in lateral view (Fig. 66) as an angulate funnel, comparatively wide basally, thereafter apically angles posteroventrally, tapered to narrowly pointed apex, in ventral view (Fig. 65) an elongate, narrow funnel; phallapodeme in lateral view (Fig. 66) irregularly Y-shaped, keel long, narrow, linear; hypandrium in ventral view (Fig. 65) as 2 narrow, parallel sided, thin sclerites, with posterior connection, in lateral view (Fig. 66) an elongate, slender, rod-like structure, bulbous posteriorly, shallowly bifurcate anteriorly.

Type material.

The holotype male of Lamproclasiopa mancha is labeled "BRAZIL. Paraná: Curitiba, UFPR [Universidade Federal do Paraná, Reserva Biológica] (25°26.9'S, 49°14'W; 915 m),6 Feb2010[,] D. & W. N. Mathis/ USNM ENT 00118310 [plastic bar code label]/HOLOTYPE ♂ Lamproclasiopa mancha Costa, Mathis & Marinoni DZUP [red]." The holotype is double mounted (minuten pin in a block of plastic), is in excellent condition, and is deposited in DZUP. Twenty-nine paratypes (24♂, 5♀; DZUP, USNM) bear the same locality data as the holotype, with dates from 9 Dec 2009-13 Feb 2010.

Distribution

(Fig. 59). Neotropical: Argentina (Misiones), Brazil ( Paraná, Santa Catarina, São Paulo).

Etymology.

The species epithet, mancha , is the Portuguese word for a stain and refers to the darkened clouds over crossveins r-m and dm-cu, diagnostic of this species.

Remarks.

This species is easily distinguished from congeners by the wing pattern. The wing is mostly hyaline except for darkened clouds over crossveins r-m and especially over dm-cu; and vein R2+3 has the apex more abruptly curved toward the costa. Sometimes the darkened spots over the crossveins are slightly faded.
