Odontocera bettyae sp. nov.

( Fig. 4 )

Diagnosis. Odontocera bettyae sp. nov. is similar to O. fasciata (Olivier, 1795) , O. zeteki Fisher, 1930 , O. barnouini Peñaherrera-Leiva & Tavakilian 2003 , O. beneluzi Peñaherrera-Leiva & Tavakilian 2003 , and O. limula sp. nov., mainly by the pronotum having transverse bands of golden pubescence. It differs from all them as follows: bands of pubescence of pronotum not well delimited; elytra without oblique black maculae on basal third; metatibiae with brush of setae. In the other species, the bands of golden pubescence of pronotum are well delimited, the elytra has oblique black maculae on basal third, and the metatibiae do not have a brush of setae.

Etymology. Odontocera bettyae is named after the mother of the first author (LGB), Betty J. Bezark, who supported his entomological career and always let him keep insects in the freezer.

Male ( Fig. 4 ). Integument black. The following reddish-brown: clypeus, labrum, mouthparts, scape, pedicel, scutellum, base of elytra, distal sixth of elytra, except margins, distal half of pro- and mesofemoral club, basal third of peduncle of metafemora, ventral surface of nearly all metafemoral club, ventral surface of protibiae, mesotibiae, basal third of metatibiae, mesotarsi, tergites I and II, except margins, ventrites I and II, except the distal extreme and narrow lateral band. The following brown: antennomere III, base of antennomere IV, dorsal surface of protibiae, pro- and metatarsi. Elytra translucent from basal fourth to about distal sixth, with narrow black band on margins. General pubescence and setae golden.

Head not elongate behind eyes (posterior edge of eyes near the anterior edge of prothorax); rostrum (between apex of inferior ocular lobe and genal apex) about as long as 0.65 times length of inferior ocular lobe in frontal view. Dorsal surface of head coarsely, abundantly punctate, obliterated by the pubescence between and below inferior ocular lobes; pubescence dense between and below inferior ocular lobes, mixed with moderately abundant long and very long setae; pubescence of area between inferior ocular lobes extended as a band up to prothorax; remaining surface of vertex less dense, mixed with short setae. Labrum dorsally with long, sparse setae, distinctly shorter and abundant on distal edge. Laterally, behind inferior ocular lobes, pubescent, mixed with long setae, gradually less pubescent and with darker and longer setae towards gena. Ventral surface of head striate-punctate on hypostomal area, mainly laterally; with long, sparse setae, mixed with short setae. Distance between inferior ocular lobes equal to 0.3 times length of one lobe in frontal view. Antennae as long as elytra, reaching middle of elytra; antennomere III filiform; antennomere IV slightly enlarged towards apex; antennomeres V–X distinctly enlarged towards apex, externally serrate; antennomeres V–XI forming a distinct club. Pedicel and antennomeres III–VI with long, dark, thick setae.

Prothorax subcylindrical, longer than wide, widest at middle, without tubercles on this area. Pronotum coarsely, abundantly punctate; densely pubescent on three wide transverse bands: one at base, one at apex, and another a little past middle, centrally interconnected to the apical one; between the basal and middle band another wide macula of golden pubescence, somewhat interconnected to the former; area on each side of this last macula with pubescence less dense, and more brownish; area between this last macula and middle ones not pubescent; area between middle transverse band and apical ones not pubescent, except on the central area of interconnection; distal and middle band of pubescence laterally fused, and extended towards lateral part of prothorax; basal band of pubescence extended towards lateral edge of prothorax, but not distinctly interconnected with the other two bands; entire surface mixed with long, abundant setae. Prosternum pubescent on basal half, mixed with very long, abundant dark setae; distal half with very long, abundant dark setae. Prosternal process moderately narrowed centrally, truncate at apex. Scutellum with short, abundant setae. Elytra long, strongly narrowed from base to apex, dehiscent at sutural distal half; reaching distal third of second abdominal segment; surface with long, sparse setae on basal third, gradually shorter towards apex; basal fifth coarsely punctate, distinctly finer, sparser on translucent area; area not translucent, coarsely, abundantly punctate. Mesepimeron densely pubescent. Metepisterna densely pubescent on distal fourth; remaining surface with long, sparse setae, except on small portion on base, somewhat pubescent. Metasternum with an oblique band of golden pubescence interconnected to that of distal portion of metepisternum and to remaining pubescent area of metasternum (not pubescent on front metacoxae, along metasternal suture, and a band on basal half close to metepisternum). Ventrites I–II with short, sparse setae; ventrite III with short, decumbent, moderately abundant setae; ventrites IV–V pubescent.

Femora clavate; metafemora distinctly longer than pro- and mesofemora; apex of metafemora reaches about basal third of ventrite III. Metatibiae with brush of setae. Metatarsomere I about as long as II–III together. Abdomen narrowed, long, ichneumoniform.

Dimensions in mm (holotype male). Total length (from mandibular apex to abdominal apex), 14.3; prothorax: length, 2.4; anterior width, 1.8; posterior width, 1.7; humeral width, 2.1; elytral length, 6.1.

Type material. Holotype male from ECUADOR, Napo: Yasuni National Park (250 m, 0º40.566’S – 76º23.851’W), IX.30 –X.11.2002, C. Brammer col. (CASC).

Remarks. Some species currently placed in Acyphoderes Audinet-Serville, 1833 , have a general appearance similar to O. bettyae . However the pronotum in O. bettyae is not longitudinally sulcate, an important character separating both genera.
