Distribution. This species is distributed in caves in the municipalities of Arcos, Campo Belo, Córrego Fundo, Doresópolis, Lagoa da Prata and Pains, many of them associated with the Arcos-Pains-Doresópolis speleological unit, which comprises the region with the highest density of caves known for South America (Fig. 1 A and B).
Etimology. Specific epithet “ painensis ” refers to the municipality Pains, type locality of the new species. This name originates in language, which cite the family “ Paim Pamplona ” around the 18th century, where was it usual pronounce the phrase “Let’s go to the farm of Paim ”, region where the name of the municipality originated.
Diagnosis. Combination of the following characters: phallic complex slightly more elongated than wide in dorsal or ventral view (Figs 5 and 6); pseudepiphallic dorsal branch underdeveloped, elongated, rounded at apex, with the presence of a small angulation, leaning in greater degree to inwards of the phallic complex (Figs 5, 7 and 9, Ps. db); pseudepiphallic paramere well developed, discoidal and concave (in dorsal, diagonal and front view) (Figs 5–9, Ps. P); a small region forming an arc partially sclerotized U-shaped (Fig. 5, blue arrow) between the bases of the pseudepiphallic parameres (Ps.P) and below the endophallic sclerite posterior portion (End.Sc.p); endophallic sclerite anterior portion well developed and sclerotized, with a groove (in ventral view); a dilated and elongated apodeme is evident after the groove (Figs 6 and 7, End.Sc.a, yellow arrow).

Body color: head, pronotum and right tegmen brown color in dorsal view (Figs 12–14, 31), slightly light yellowish brown ventrally, as well as the abdomen (Fig. 15); legs slightly light yellowish brown at base and medium brown in the extremities, cerci pubescent and brown (Figs 17 and 18). Head: slightly pubescent, elongated in front view (4.65 and 3.43 mm, length and width respectively), vertex brownish, with a central band reaching the occiput; gena, clypeus, frons and labrum light yellowish brown, mandibles brown whitish and sclerotized in all its extension; first two maxillary palpomeres of similar proportion, smaller than the third and fourth that have the same proportion, fifth palpomere greater than the fourth, slightly elongated, claviform format, light yellowish brown and curved at apex; first, second and third labial palpomeres crescent in size, slightly pubescent, third claviform; scape, pedicel and antennomeres medium brown and pubescent, the region between the antennas has well developed bristles; compound eyes developed, slightly surrounded by depigmented ommatidium, and with a small depigmented dorsal field where scape fits; ocelli absent (Figs 11 and 12). Thorax: pronotum pubescent, with long bristles around the anterior and posterior extremities, a lighter vertical band crosses the center of the structure, lateral lobes rounded (Figs 13 and 15). Leg I: femur and tibia of similar size; oval auditory tympanum in the ventralproximal region of the tibia (Fig. 19–I, (t) highlighted in yellow); tibia armed with a pair of ventro-apical spurs of the same-size; first tarsomere serrulated, greater than the second and third tarsomeres (Fig. 19 –I–II). Leg II: tibia with a pair of internal and external apical spurs, dorsal smaller (Fig. 16 –III–IV, μ and λ highlighted in yellow). Leg III: femur developed; tibia serrulated of proportional size to the femur, armed with a sequence of three internal subapical spurs (Fig. 19–V, α, β and γ highlighted in yellow) and four outer side (Fig. 19 –VI, w, x, y and z highlighted in yellow), distal spur smaller (Fig. 19 –VI, z); four apical spurs at inner (Fig. 19–V, d, e, f and g highlighted in yellow) and and three at outer side (Fig. 19 –VI, a, b and c highlighted in yellow); three tarsomeres present, first serrulated distally and more elongated than the second and third, with a pair of apical spurs, the inner longer (Fig. 19 –V–VI, θ and δ highlighted in yellow). Right tegmen developed and sclerotized, covering the first three abdominal tergites (Fig. 15); mirror oval with three crosse-vein and fourth cells, first caudal vein has two small discontinuous branches and a small secondary cell; harp with six cross-veins, the last three caudal cells connected to a diagonal vein; lateral field with two large vertical cells and numerous accessory veins, from those are projected numerous irregular vein, some of these may be efurcate; basal field vein 1A, 2A, and 3A not furcate, main route leading up to the meeting of the 1A and 2A presents two small secondary cells (Figs 11 and 17); stridulatory file with 91 teeth.
