(Figs 1, 2, 5, 7, 8, 10–12)
Diagnosis. In Casal’s (1963) key to females of Lynchiatilla species, L. parana runs to couplet 6 and is related to L. tacana Casal, 1963. Females of these two species can be separated as follows: L. parana without genal carina, and T2 with two rounded, golden, pubescent maculae (Fig. 1); L. tacana with genal carina, and T2 with two longitudinal oval, pale white, pubescent maculae (Fig. 3). The males can be separated as follows: L. parana with metasomal integument black and T2–T6 apically with dense transverse rows of pale golden setae (Fig. 7); L. tacana with metasomal integument orange and T2–T6 apically with sparse white setae laterally and red-brown in the middle with a few white setae intermixed (Fig. 9). The wings are very similar, but differ slightly in the shape of the first submarginal cell (Figs 5–6).
Description. FEMALE (holotype, Figs 1, 2). Body length 8.5 mm. Color: integument of head and mesosoma red; scape, pedicellus, and first three flagellomeres orange-yellow, other antennomeres black; mandible orangeyellow except tip black; legs orange-yellow; T1 red except apex black; T2–T6 black except discal area of T2 with two broad, transverse, red maculae hidden in part by pubescence; S1 red; S2 black except basal third red; S3–S6 black. Frons and vertex with sparse black setae; gena and clypeus mostly with pale white setae; dorsum of mesosoma with sparse black setae except propodeum with sparse pale golden setae; sides of pronotum with sparse pale pubescence; mesopleuron with very few pale setae; T1 with pale golden setae except apex with black setae medially; T2 with black setae except for lateral area with white setae and two discal rounded spots of golden pubescence covering parts of the two red integumental spots; T3–T5 with dense golden pubescence interrupted in middle by black setae; T6 basal half with intermixed pale golden and black setae; S1–S4 with pale white setae; S5–S6 with pale golden setae.
Head: rectangular; with deep medium-sized punctation, mostly semiconfluent and confluent, sculpture not hidden by pubescence; eye large, distance between posterior margin of eye and postero-lateral angle about 0.65 × maximum diameter of eye; scrobal carina present, not reaching base of antennal tubercle; genal carina absent; clypeus with anterior margin straight, medial area with a weak, arcuate, transverse ridge ending in anterior margin near tubercle in front of each antennal tubercle; antenna slender, first flagellomere 1.4 × as long as second in dorsal view; mandible with apex bidentate, simple beneath without any tooth or process.
Mesosoma: 1.2 × as long as wide (excluding prothoracic collar); lateral margin distinctly sinuate, gradually narrowing to propodeal spiracle then broadening posteriorly; dorsally with punctation very similar to head; propodeal dorsal face with large punctures, deep, longitudinally irregular and confluent; mesopleuron micropunctate, metapleuron and side of propodeum smooth and glabrous; lateral margin of mesonotum with a very small tooth between prothoracic and propodeal spiracles; propodeal margin with three very small spines anterolaterally and a transverse row of seven large spines or projections posteriorly.
Metasoma: T1 not constricted posteriorly, sessile and evenly merging with T2, basal two-thirds with small sparse punctures, apical third with small close punctures; T2 evenly convex throughout, without elevated, longitudinal carinae, mostly with medium-sized, dense, contiguous and somewhat confluent punctures; T3–T5 with small, close punctures; T6 with flattened medio-apical microgranulate area defined by distinct lateral carina; S1 mostly smooth but with a prominent, median, longitudinal keel; S2 with medium-sized close punctures; S3–S5 with small, close punctures; S6 with medium-sized, contiguous punctures except apical third smooth.
MALE (allotype). Body length 9.0 mm. Color: Integument black; tibial spurs pale white; body and legs covered with sparse, simple, white setae, except near inner margin of eyes, mesoscutum, tegula and anterior third of scutellum with black setae; metasomal segments 2–6 apically with dense transverse rows of pale golden setae.
Head: transverse in dorsal view, sub-rounded; frons, vertex and gena with medium-sized, very close punctures; eye 0.5 × as long as medial length of head; ocelli small, distance between eye margin and lateral ocellus 7 × diameter of ocellus; genal carina absent; clypeus convex mesally, its antero-medial margin almost straight and untoothed; proboscidial fossa large, extending laterally to insertion of mandible; mandible slender, bidentate apically, simple ventrally; scrobal carina reduced to an inconspicuous protuberance between antennal tubercle and eye; antennal tubercle simple, without protuberance or carina; scape with a single longitudinal carina below; first flagellomere as long as second.
Mesosoma: pronotum, mesoscutum and scutellum with medium-sized, very close punctures; tegula convex, without a distinct posterior surface, smooth and shiny but with a few punctures along anterior and lateral margins; scutellum slightly convex; dorsum and posterior face of propodeum broadly reticulate; pronotum with humeral area rounded, lateral area with short transverse carina ventrally; mesopleuron anterior one-third with small separated punctures, posterior two-thirds with medium-sized very close punctures, dorsal and ventral areas separated by broad and deep scrobal groove; metapleuron and propodeum laterally mostly glabrous and impunctate; forewing with three submarginal and two discal cells, veins 3rs-m and 2m-cu faintly indicated, nebulous (Fig. 5).
Metasoma: T1 not constricted posteriorly, sessile and evenly merging with T2, about as long as wide, 0.5 × length and 0.62 × width of T2, mostly smooth with few small punctures, except apically and laterally with small, very close punctures; T2 covered with medium-sized, close punctures except apex with small, very close punctures, with lateral felt line about 0.57 × as long as lateral margin; T3–T6 with small, very close punctures; T7 basal half with medium-sized, very close punctures, apical half with intermixed microgranulate and irregular rugose sculpture; S1 with a median longitudinal carina; S2 without felt line; S1, S2 and S7 with medium-sized punctures; S3–S6 with small, very close punctures; hypopygium apex with deep, V-shaped, medial emargination (Fig. 8); genitalia: paramere with apex simple, basal half not very broad, distal half gradually narrowing toward apex (Fig. 10), ventral margin with long setae, except apical one-fourth with row of sparse short setae; volsella with cuspis and digitus short (Fig. 11), cuspis with long setae; penis valve with apical tooth and lacking preapical tooth (Fig. 12).

Paratypes: 1 Ƥ same data as holotype (MIUP); same data except 03.I.2008 (1 Ƥ, DZUP 167630); same data except 07.I.2008 (1 Ƥ, DZUP 167631); same data except 04.III.08 (1 Ƥ, DZUP 167632); same data except 15.XI.2008 (3 Ƥ 1 ♂ DZUP 167633, 167634, 167636, 167637); Brazil, Paraná, Curitiba [25°26'S 49°16'W], 15.XI.1965, col. C.D. Michener (1 Ƥ, MIUP).
Variation. The female specimen from Curitiba has the integument of the metasoma mostly red instead of mostly black.
Distribution. Brazil (Paraná).
Etymology. The species is named in reference to Paraná, the Brazilian State from which the specimens have been collected, used here as a noun in apposition.
