Trachelissa bella sp. nov.

( Figs. 64–76 , 135–136 , 157 , 160 )

Trachelia maculicollis ; Wappes et al., 2006: 23; Clarke, 2007: 158 (non Audinet-Serville, 1834)

Male. Integument generally brownish red. Head, prothorax and scutellum slightly darker than rest of body. Scape, pedicel and antennomeres III–V brownish red; VI–XII brownish yellow, antennomeres III–XII with dark-brown or black apices. Mesosternum, metasternum and abdomen orange to brown. Elytra with two pairs of irregular eburneous callosities, in median region, very close each other; these callosities continue in eburneous lines that do not reach the elytral apices.

Frons with yellowish setae. Vertex with fine dense punctures; short, dense yellowish setae. Antennal tubercles with smooth and glabrous apex. Upper eye lobes well separated, distance between them twice width of upper lobe; lower eye lobes about three times wider than upper lobes. Genae as long as half diameter of lower eye lobes; short, dense yellowish setae.

Antennae reaching elytra apices at antennomere VI or VII; pedicel and antennomeres III–XII with fine, shallow dense punctures; short, dense yellowish setae; antennomeres III–XI with smooth and glabrous apices; antennomere III with longitudinal groove; antennomere IV not grooved; antennomeres IV–VI and VII–XI subequal in length; antennomere XII with 1/3 shorter than III and subequal in length to XI.

Prothorax with shiny surface; prothorax subparallel at sides; pronotum with two rounded tubercles near posterior margin. Pronotum with evident sexually dimorphic punctuation, except in longitudinal band on posterior half with very fine and indistinct punctures, and two oval and oblique regions with fine sparse punctures; short sparse setae. Sexual punctation on prosternum with coarse, dense and some irregular punctures; long, erect yellowish setae. Prosternal process slightly expanded to apex and chamfered. Mesosternum depressed. Scutellum with short, decumbent, moderate to dense whitish setae.

Surface of elytra almost smooth, with sparse fine punctures. Sternite I 1 /3 longer than II; sternites II–IV subequal in length; sternite V with rounded apical margin. Female. Antennae black, except scape and inner basal region of antennomeres IV–VII brownish red. Prosternum, mesosternum and metasternum varying from brown to black. Mesosternal process varying from brown to orange. Sternites I–V brownish red with apical margin dark brown.

Frons with brownish setae. Antennae reaching the elytra apices at antennomere IX; antennomeres distinctly serrate; antennomeres III–VII with smooth and glabrous apices; antennomeres VII–X gradually decreasing in length; antennomere XI half length of III and 1/3 longer than X. Pronotum and sides of prothorax with smooth and subglabrous surface; prosternum with fine sparse punctures; short, sparse whitish setae. Prosternal process measuring half diameter of procoxal cavity. Sternite V with slightly truncate apical margin.

Measurements (mm). male/female. n= 2/2. Total length 9.6–10.4/10.2; prothorax length 2–2.3/2; greatest prothorax width 2–2.2/2; elytral length 6.2–6.8/6.6–7.2; humeral width 2.4–2.6/2.7.

Type material. Holotype male. BOLIVIA. Santa Cruz: 20.IX.1955, Zischka leg. ( USNM). Paratypes: N. Achira (4–5 Km, Rd. a Amboro), female, 12–13.X.2000, Wappes & Dozier leg. ( ACMT); Buena Vista (4–6 Km SSE, F. & F. Hotel), male, 15–29.VIII.2003, R. Clarke leg. ( ACMT); Buena Vista (5 Km SSE, 17º29’96’’S 63º39’13’’W, 440 m), female, 4.IX.2005, R. Clarke & S. Zamalloa leg. [In flowers of Calliandra haematocephala ] ( MCZN).

Etymology. The specific epithet is a derivative of the Latin word bella (=cute, pretty) referring to the shape of the body.

Comments. Trachelissa bella sp. nov. differs from the other species of Trachelissa by the antennae, which in males are distinctly long, reaching the elytral apices at antennomere VII; and the elytra with two pairs of eburneous callosities, in median region, very close to each other; these callosities continue in eburneous lines that do not reach the elytral apices. This species was reported by Wappes et al. (2006) and Clarke (2007) as Trachelissa maculicollis , who provided illustrations, and recorded the geographic distribution, and noted that they were visiting flowers.

Geographical distribution. Bolivia (Santa Cruz) ( Figs. 157 , 160 ).

Biological data. Clarke (2007) mentioned that T. maculicollis ( T. bella sp. nov.) visited flowers of Calliandra haematocephala Hassk. (Mimosaceae) .
