Trichohippopsis birai Galileo and Santos-Silva , new species

Description. Holotype female. Integument primarily brown. The following dark brown: narrow, longitudinal band on center of vertex; wide band from posterior edge of upper eye lobes and margin of prothorax; apex of genae; wide, longitudinal band on dorsal surface of scape; apex of scape (including cicatrix); smooth apical area of antennomeres III–X; anterior margin of pronotum; narrow, smooth, central area on pronotum; wide band close to elytral suture, from base to before middle (narrowed, away from suture toward its apex, gradually lighter after apex of basal third); most of legs. The following reddish brown: mouthparts; remaining surface of elytra; parts of coxae; most of abdominal ventrites. Pubescence and setae yellowish, except for very long dark brown setae, and distinct yellow on areas with dense pubescence. Head: Coarsely, abundantly punctate, interspersed with fine, abundant punctures (mainly centrally); with short, moderately sparse setae laterally, denser on central, longitudinal area; with long, sparse setae throughout, with some very long setae close to lower eye lobes. Antennal tubercles with sculpture and setae as on frons on its frontal and inner side, punctures distinctly finer, with sparse, short setae on basal outer side, smooth, glabrous toward apex of outer side. Vertex moderately coarsely, densely punctate; with short, moderately sparse setae laterally, denser centrally; with long, sparse setae throughout, with long setae on each side near upper eye lobes. Area laterally behind eyes with sculpture and setae as on vertex; with fovea close to base of lower eye lobe; distinctly tumid close to lower eye lobe; with very long setae near inferior side of lower eye lobes. Genae moderately coarsely, sparsely punctate (also slightly transversely striate), gradually finer, sparser toward smooth band close to apex; with short, sparse setae, glabrous on smooth area; with very long setae toward ventral side. Gula transversely, finely, striate centrally close to submentum, smooth on remaining surface; 0.7 times as long as length of lower eye lobe. Submentum transversely striate; with short, sparse setae. Distance between upper eye lobes 0.10 times length of scape; distance between lower eye lobes in frontal view 0.55 times length of scape. Antennae 1.8 times elytral length, reaching elytral apex at basal third of antennomere IX; apex of antennomeres III–X smooth, shiny; antennal formula based on antennomere III: scape = 1.19; pedicel = 0.28; IV = 1.43; V = 1.43; VI = 1.33; VII = 1.19; VIII = 1.16; IX = 1.14; X = 1.02; XI = 1.21. Thorax: Prothorax about as long as wide (slightly wider at anterior margin, slightly narrower at basal margin); slightly divergent from base to apex laterally. Pronotum moderately coarsely, abundantly punctate, except for narrow, smooth, longitudinal central area; with short, moderately abundant setae (not obscuring integument), sparser on large area placed laterally between anterior third and sixth, glabrous on central smooth area; with long, erect, moderately sparse setae throughout. Sides of prothorax with sculpture as on pronotum, except for narrow, transverse area close to anterior margin with fine, sparse punctures; with short, moderately abundant setae (not obscuring integument). Prosternum moderately finely, abundantly punctate on basal half and anterior third, interspersed with very fine, abundant punctures, transversely striate between these areas; with short, moderately abundant setae on basal half, sparser on distal half, interspersed with long, sparse setae. Prosternal process narrow at basal half (about 1/4 as wide as base of profemoral peduncle). Metasternum pubescent laterally, slightly denser toward longitudinal, narrow, central glabrous region, interspersed with long, sparse setae. Metepisterna pubescent (pubescence distinctly denser on narrow area close to margins). Scutellum densely pubescent. Elytra moderately coarsely, abundantly punctate on basal half, slightly finer, sparser toward apex; with short, abundant setae throughout, distinctly denser on narrow band close to suture at anterior third; with long, thick, sparse setae throughout; apex rounded. Legs: Femora finely, moderately abundantly punctate (rugose on base of profemora), with short, sparse setae, distinctly denser ventrally, interspersed with long setae. Tibiae with brush with dense setae ventrally (less so on metatibiae), with brush of dense setae dorsally on mesotibiae; all tibiae with very long, sparse, thick setae. Abdomen: Ventrites I–IV microsculptured, interspersed with fine punctures; pubescence partially obscuring integument, except for central area on ventrite I; ventrite V finely, moderately abundantly punctate, with pubescence sparser than remaining ventrites, mainly on center of basal area; ventrite V transversely depressed close to apex (central area wider); apex of ventrite V truncate, centrally with small emargination.

Dimensions. Holotype female. Total length (including mandibles) 17.5 mm; prothoracic length 2.6 mm; anterior prothoracic width 2.6 mm; basal prothoracic width 2.4 mm; humeral width 3.5 mm; elytral length 12.3 mm.

Type Material. Holotype female from BRAZIL, Amazonas: Itapiranga (Rod. AM 363 , km 111, Ramal Madubá, 021°42′57″S / 58°00′46″W; “21 às 00:00h”; light trap; “dossel 30 m ”), 6-7.X.2010, D. Ochoa, R. Machado, and M. Guedes col. ( INPA).

Etymology. The new species is named after the late Ubirajara Ribeiro Martins de Souza (Bira).

Remarks. Trichohippopsis birai is similar to T. magna , but differs mainly by the pronotal and elytral pubescence not obscuring the integument (distinctly obscuring it in T. magna ), and by the longer erect setae of the elytra (shorter in T. magna ). It differs from T. suturalis as follows: metasternum and abdominal ventrites finely, sparsely punctate, partially obliterated by pubescence (coarser, more abundantly punctate, not obliterated by pubescence in T. suturalis ); elytra with long, erect setae throughout (distinctly shorter, present mainly on basal third in T. suturalis ); cicatrix of scape large, very distinct in dorsal view (smaller, slightly distinct in dorsal view in T. suturalis ); antennomere III shorter than V (longer in T. suturalis ). In having antennomere III shorter than V, it resembles T. unicolor , T. gilmouri ( Figs. 5 , 15 ), and T. rufula ( Figs. 9–11 ). But it differs from the former by having the prothorax about as long as wide (distinctly longer in T. unicolor ); it differs from T. gilmouri and T. rufula mainly by the more robust body ( Fig. 1 ).
