( Figs 1, 2 View FIGURES 1 – 4 , 5, 7, 8, 10–12 View FIGURES 5 – 14 )
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 View FIGURES 1 – 4 ); L. tacana with genal carina, and T2 with two longitudinal oval, pale white, pubescent maculae ( Fig. 3 View FIGURES 1 – 4 ). 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 View FIGURES 5 – 14 ); 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 View FIGURES 5 – 14 ). The wings are very similar, but differ slightly in the shape of the first submarginal cell ( Figs 5–6 View FIGURES 5 – 14 ).
Description. FEMALE (holotype, Figs 1, 2 View FIGURES 1 – 4 ). 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 View FIGURES 5 – 14 ).
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 View FIGURES 5 – 14 ); genitalia: paramere with apex simple, basal half not very broad, distal half gradually narrowing toward apex ( Fig. 10 View FIGURES 5 – 14 ), ventral margin with long setae, except apical one-fourth with row of sparse short setae; volsella with cuspis and digitus short ( Fig. 11 View FIGURES 5 – 14 ), cuspis with long setae; penis valve with apical tooth and lacking preapical tooth ( Fig. 12 View FIGURES 5 – 14 ).

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.
