Distribution. So far known from three Brazilian states ( Fig. 21 ), from the Central-West and Southeast regions of the country.

Etymology. bi - (Latin), two; punct - (Latin), punctation; and suffix - ata (Latin), characterized by having; referring to the pair of white marks on anterior lobe of pronotum.

Discussion. The new species can be distinguished from all other species of the genus by the pronotum dark brown with a pair of large white maculae on anterior lobe; presence of white swollen areas of cuticle on thorax ( Fig. 5 B); number and distribution of white maculae on forewings ( Fig. 5 D); presence of short black denticles on male and female femora and tibiae; and shape of last abdominal sternite ( Fig. 5 B), proctiger, and parameres of male ( Fig. 6 I).

Paravelia bipunctata sp. nov. superficially resembles P. capixaba Moreira, Nessimian & Rúdio, 2010 and P. conata (Hungerford, 1929) . In relation to P. capixaba ( Figs 14 C–D), the two species share abundant long setae on antennae and legs, absence of small tubercles between meso- and metasternum, the presence of a large and deep punctation on inner portion of mesoacetabulum, and short conical setae on venter of fore femur. The new species is, however, much darker than P. capixaba , very long dorsal setae are present only on the body of the latter, and the structure of mesoacetabulum is centrally extended only in P. capixaba . The fore tibial grasping comb is very evident in P. capixaba , but not distinct in P. bipunctata sp. nov., and male parameres are much thinner and longer on the latter species. In the case of P. c o n a t a ( Fig. 15 A), both species have the following characters in common: a pair of white maculae on anterior lobe of pronotum; color pattern of legs; short conical black setae and short black denticles on fore and hind tibiae; areas between abdominal connexives covered by silvery pubescence; and anterior margin of sternites III–VII with transversal areas without setae. However, P. conata has a large conical projection on dorsum of pronotum ( Fig. 15 A), absent in the new species.

Rostrum brown, except apex of article III and IV, shining black. Pronotum dark brown to black, anterior lobe lighter. Pro-, meso- and metapleura dark brown; acetabula brown. Prosternum brown, meso- and metasternum darker. Coxae, trochanters, and base of femora light brown, remaining of legs darker. Forewing dark brown, veins lighter, with black areas between cells; tear-shaped white macula at base, starting from humeral angle and surpassing the posterior margin of pronotum; a small elongated white macula on apex ( Fig. 7 A). Abdominal segments light brown, with a dark brown band in the region of spiracles; genitalia yellowish brown ( Figs 7 B–C).

Head covered by golden pubescence, and long dark setae more concentrated medially in front of eyes, with a pair of rounded punctations near posterior margin. Antenniferous tubercles shiny and swollen. Antennae finely pubescent; antennomere I stoutest, curved outward; segment II shorter; segment IV longer than III ( Fig. 7 A). Ocular setae present. Jugum with minute black denticles. Rostrum reaching base of mesocoxae.

Pronotum covered by black setae, more concentrated on anterior lobe and apex of posterior lobe; median carina present, more evident between humeral angles, which are slightly elevated. Posterior lobe with lateral margins near apex slightly elevated. Costal margins and radial veins of forewings with thick black setae. Propleura with a pruinose silvery area just behind eyes. Pro- and mesopleura each with a row of 4 – 5 rounded punctations, and metapleura with about 10 punctations, not arranged in rows. Pronotal collar with 5 rounded punctations. Intersegmental region between meso- and metasternum with two pairs of small tubercles. Mesoacetabula with a rounded punctation near mesosternum. Legs covered by fine, short, golden setae, sparsely intermixed with long setae; without spines ( Fig. 7 B). Foreleg with small grasping comb.

Connexiva and lateral margin of abdominal segments covered by golden pubescence and long dark setae. Abdominal connexives slightly elevated. Posterior angle of last connexival segment slightly developed ( Fig. 9 A). Superior portion of gonocoxae, and lateral area of posterior margin of abdominal tergite VII with small black denticles.

Type-material. Holotype: Brazil, Minas Gerais: macropterous female (MZUSP), Serra do Caraça, 1.380 m a.s.l., XI.1961, (Kloss, Lenko, Martins & Silva).

Distribution. Only the holotype collected at high altitude on Serra do Caraça, a mountain range which includes areas of the municipalities of Santa Bárbara and Catas Altas ( Fig. 21 ), Southeastern Brazil, is known up to the present.

Etymology. lacrimosus- (Latin), tear; referring to the tear-shaped maculae on the forewings.

Discussion. The new species can be distinguished from all other species of the genus mainly by the length of body (5.52 mm); dorsal coloration dark brown, constrasting with the light brown of the abdominal segments; anterior lobe of pronotum without distinct maculae or pruinose areas; white tear-shaped basal maculae on forewings ( Fig. 7 A); absence of rounded punctations on abdominal sternites; and gonocoxae and posterior margin of abdominal tergite VII with black denticles.

Other species recorded from mountain ranges of Minas Gerais State are P. bipunctata sp. nov. ( Fig. 5 ), P. lanemeloi Moreira & Barbosa, 2012 ( Fig. 17 B) and P. nieseri Moreira & Barbosa, 2012 ( Fig. 17 D). These can be distinguished from P. lacrymosa sp. nov. by the basal macula of the forewing not starting from humeral angles, contrarily to P. lacrymosa sp. nov. Also, in P. lacrymosa sp. nov. the basal maculae of forewings surpass the posterior margin of pronotum (which does not occur in P. bipunctata sp. nov.); exposed areas of connexives are dark brown (light brown in P. lanemeloi ), and head and posterior margin of pronotum are dark brown to black (orange in P. nieseri ).
