Colydodes flavisetis

description: Colydodes flavisetis Ferreira & Ide-dos Santos, sp. nov.
(Figs 1–16)
Diagnosis. The strongly produced pronotum extending anteriorly over the head with disk area deeply notched anteriorly and the conspicuous yellowish brush-like setae under the dorsal projections of the pronotum distinguish this species from the other known Colydodes.
Description. General coloration: dark brown. Vestiture: dorsally and ventrally covered with yellowish scalelike setae; ventrally with less dense. Head prognathous, dorsoventrally flattened, impressed with sparse microtubercles, each one bearing a single seta; frons large, with rounded lateral margins, flat in the middle and prominent laterally over the scape, lateral margins rounded; posterior portion of head convex, hidden when the head is raised (Fig. 8), with a smooth area on each side (Figs 6–7). Gula covered with small setae (Fig. 9). Clypeus fused to cephalic capsule, curved downwards. Labrum free, rounded, anterior margin bearing a row of yellowish setae. Eyes lateralized, coarsely granulated, with setae between ommatidia (Figs 10–11). Antennae 11-segmented, with sparse setae on the surface, scape wider and twice as long as the pedicel, segments I–III sparser than III–XI, the last three segments forming a club, club segments with few aristate setae, segment XI with a high concentration of small setae at the apex (Fig. 10). Maxillary palpus 4-segmented, apical segment robust, fusiform, with a pointed tip, approximately twice as long as segment III, palpomeres I–III subequal in length, palpomeres with sparse setae.
Labial palp 3-segmented, segment III wider, robust, twice as long as II, segment I 1 /2 shorter than I. Mentum transverse, ventral surface concave, anteriorly with a median tooth between two depressions, lateral and anterior margins with sparse setae; ligula slightly notched anteriorly, with two pairs of setae ventrally (Figs 9–10). Pronotum longer than wide (length/width = 1.43), with anterior margin bearing small anterolateral tubercles, tubercles triangular when viewed laterally, separated from adjacent structures, with a slender projection over transverse canal; pronotal disk with two paired medial tubercles strongly produced towards head, but not reaching it, with anterior edge of the two paired medial tubercles convergent, diverging and widening backwards; posterior part of medial tubercles extending over transverse canal, notched at middle, bearing brush like yellowish setae under projections (Figs 1–2, 12–13); pit present between medial tubercles; transverse canal connected to anterior part of lateral and median canals; lateral canals divided longitudinally by a ridge; ridge divided in the middle by a secretory pit; median canal concave, without margins, almost reaching basal canal, separated by a line of microtubercles; basal canal concave, almost complete, separated from accessory canal by two microtubercles on each side; accessory canal small, concave, bearing a pair of pits; disk area densely microtuberculate, split in two by median canal, each side of the pronotal disk divided at the anterior third by a deep oblique notch, forming an anterolateral and an anteromedian lobe, both lobes rounded and bearing brush-like yellowish setae ventrally and curved over part of the transverse canal, almost reaching the posterior projections of the median tubercles; notch almost reaching the median canal posteriorly, separated by a single microtubercle. Elytra elongate, with parallel sides, narrower at round apex, each elytron with 9 rows of subquadrate punctures, with a single microtubercle bearing a scale-like seta between punctures (Figs 3–4, 14). Aedeagus symmetrical, pointed apically (Figs 15–16). Parameres robust, slightly longer than median lobe, median struts long, almost reaching apex of phallobase. Phallobase symmetrical, divided dorsally, 1/3 longer than parameres.
Type material. Holotype (♂) deposited at Museu de Zoologia da Universidade de São Paulo (MZSP): Labeled: Brazil, SP, Salesópolis, Estação Biológica de Boracéia, 23°39' 2,6°S, 45° 53' 32, 1° W, 17–21.VI.2013, V.S.Ferreira, F.F. Barbosa, E.A. Abrantes colls. Fixed in laboratory on: 31.I.2014 by V.S. Ferreira.
Etymology. From latin: flavu s (yellow) + setis (dative plural of seta, setae) referring to the yellowish brushlike setae under the pronotal projections (tubercles and lobes) over the transverse canal.
