Desmiphora (Desmiphora) iwasarai Nascimento & Santos-Silva sp. nov.

( Figs. 5–8 View FIGURES 5 – 8 )

Description. Holotype male. Color. Head, pronotum, sides of prothorax, and ventral side of meso- and metathorax dark-brown, almost black on some regions; labrum dark reddish-brown; prosternum reddish-brown; abdominal ventrites dark reddish-brown; scape and pedicel dark-brown; antennomeres III–XI reddish-brown; elytra darkreddish-brown, except on large dark-brown macula on each side of basal third (reaching epipleura, obliquely narrowed from base to apex on dorsal region); legs reddish-brown.

Head. Frons moderately finely, abundantly punctate; with abundant, decumbent, yellowish-white setae (obscuring integument), interspersed with erect, yellowish-white setae. Area between antennal tubercles and posterior edge of upper eye lobes moderately finely, abundantly punctate; with short, decumbent, yellowish-white setae, partially obliterating integument, interspersed with long, erect (longer than on frons), yellowish-white setae, more abundant between upper eye lobes. Remaining surface of vertex with dense, decumbent, yellowish-white setae, without erect setae. Tempora with yellowish-white, decumbent setae, partially obscuring integument (mainly behind upper eye lobes), interspersed with long, erect, yellowish-white setae close to eye (mainly behind upper eye lobes). Genae fine and transversely striate, sparsely punctate area closer to apex; with short, decumbent, yellowishwhite setae toward ventral side; area closer to clypeus, and area close to apex, glabrous on large central region closer to eye. Antennal tubercles with short, decumbent, yellowish-white setae (partially obscuring integument), interspersed with long, erect, moderately abundant, brownish and yellowish-white setae. Labrum with moderately short, decumbent, golden setae (not obscuring integument), interspersed with long, yellowish-white setae directed forward. Distance between upper eye lobes 0.20 times length of scape; distance between lower eye lobes in frontal view 0.85 times length of scape. Antennae 1.8 times elytral length, reaching elytral apex by base of antennomere IX; scape with decumbent, abundant, yellowish-white setae (partially obliterating integument), interspersed with long, erect, moderately abundant, yellowish-white and brown setae; pedicel and antennomeres III–XI with decumbent, yellowish-white setae not obscuring integument, dorsally and laterally interspersed with long, erect, brown setae, about as long as diameter of segment, sparser, partially yellowish toward distal segments; ventral side of pedicel and antennomeres III–XI with long, erect, brown setae, about as long as three times diameter of segment, sparser toward distal segments; antennal formula (ratio) based on antennomere III: scape = 0.89; pedicel = 0.25; IV = 1.09; V = 0.54; VI = 0.45; VII = 0.45; VIII = 0.45; IX = 0.43; X = 0.43; XI = 0.43.

Thorax. Prothorax slightly wider than long (1.1 times); sides with small, conical tubercle on basal third; sides moderately coarsely, abundantly punctate; with decumbent, yellowish-white pubescence partially obscuring integument, interspersed with long, erect, moderately abundant, yellowish-white setae. Pronotum coarsely, abundantly punctate except on finely, transversely striate basal plate interspersed with coarse punctures; pubescence as follows: with oblique, wide, dense band with white pubescence from laterobasal angle to center of distal margin; area between white band and lateral tubercles with yellowish-brown pubescence partially obscuring integument; with wide, longitudinal, band with yellowish-brown pubescence centrally on basal 2/3; with yellowish-brown pubescence on distal third between white bands, gradually yellowish-white toward margin, denser closer to longitudinal band; with yellowish-brown pubescence on each side of apex of longitudinal band, distinctly not obscuring integument, gradually sparser toward base. Distal third of pronotum ( Fig. 4 View FIGURES 1 – 4. 1 ) with long, erect, moderately abundant, brown setae close to margin (yellowish toward sides), and another set of similar setae on each side of apex of center-longitudinal band with yellowish-brown pubescence; remaining surface with sparse, long, erect, brown and yellowish setae. Prosternum with yellowish-white pubescence, distinctly not obscuring integument, interspersed with long, erect, yellowish setae; prosternal process with abundant, sub-erect yellowishwhite setae interspersed with long, erect setae. Ventral side of mesothorax with short, sparse, yellowish-white, distinctly denser laterally. Metepisternum and sides of metasternum with yellowish-white pubescence, not obscuring integument, gradually sparser white toward center of metasternum. Scutellum with yellowish-brown pubescence obscuring integument. Elytra. Coarse and abundantly punctate on basal third, gradually sparser, finer on remaining surface (mainly after middle); pubescence as follows: with wide, dense, slightly oblique band of white pubescence on basal quarter, following that on pronotum, narrowed, less conspicuous, distinctly oblique from apex of basal quarter toward distal quarter near suture, then forming a semi-elliptical band on distal third (this band more yellowish-brown close to wide basal region); with narrow, whitish band along suture, from scutellum to base of distal third; distal third with white, abundant pubescence, making semi-elliptical band slightly distinct; basal third with large comma-shaped area with yellowish-brown pubescence distinctly exposing integument, following the dark area on pronotum; between comma-shaped region and sutural white band, with yellowishbrown pubescence gradually denser toward inner side; central area with yellowish-brown pubescence, gradually whitish toward distal third. Elytral surface with long, erect, thick, sparse, darkened setae throughout, distinctly yellowish, finer, more abundant laterally. Legs. With yellowish-white pubescence, not obscuring integument, interspersed with long, erect, moderately sparse yellowish setae throughout; tibiae dorsally also with long, erect, thick, darkened setae.

Abdomen. With decumbent, white pubescence, not obscuring integument, interspersed with long, erect, white setae; apex of ventrite V rounded.

Dimensions in mm (male).Total length (from apex of head to elytral apex), 6.95; prothorax: length, 1.75; anterior width, 1.60; posterior width, 1.60; largest prothoracic width (between apices of spiniform tubercles), 1.95; humeral width, 2.20; elytral length, 4.65.

Type material. Holotype male from BRAZIL, Bahia: Piatã, Cachoeira do Patrício (13°05’11.1”S / 41°51’13.3”W; 1256 m), 4–5.XI.2013, F.E. Nascimento, E. Menezes, J. Carvalho, D. Cordeiro and F. Bravo leg. ( MZSP). GoogleMaps

Etymology. This species is name in honor of the biologist Tammy Iwasa Arai.

Remarks. The holotype was with a great number of scales of Lepidoptera. We removed many of them, but the specimen remains with scales, because we prefer do not risk damage the specimen during the process. Desmiphora (Desmiphora) iwasarai sp. nov. is similar to Desmiphora (Desmiphora) sarryi Tavakilian & Néouze, 2004 , by the dense white pubescence on the vertex that following in two diverging bands on the sides of the pronotum extending until the third of the elytra, where converge toward the distal suture. It distinguishes mainly by the pronotum with longitudinal band with yellowish-brown pubescence in the middle region, by the apical third of elytra with a semielliptical band of white pubescence, and lacking transverse bands of white pubescence on the apical third of the elytra. In Desmiphora (Desmiphora) sarryi the pronotum has no longitudinal band in the midline, and the apical third of the elytra has transverse white band of white pubescence.
