Monneoncideres cristata Nearns and Swift View in CoL , sp. nov.
( Figures 3 View Figure 3 a-d)
Description. Female. Length 15.0 mm (measured from vertex to elytral apices), width 6.0 mm (measured across humeri). Habitus as in Fig. 3a View Figure 3 . General form elongate-ovate, robust, moderate-sized. Integument ferrugineous with testaceous pubescence; portions of head, pronotum and basal 1/3 of elytra with ferrugineous and dark brown pubescence.
Head with frons distinctly flat, roughly subquadrate, about 3 times width of lower eye lobe ( Fig. 3c View Figure 3 ). Eyes with lower lobes large, oblong; narrowest area connecting upper and lower eye lobes about three ommatidia wide. Genae roughly subquadrate, about 1/2 as tall as lower eye lobes.
Antennae about as long as body; antennal tubercles feeble, moderately separated; tubercles armed at apex with short blunt tooth; scape clavate, a little shorter than antennomere III, about as long as IV; basal 1/4 of scape with underside slightly rugose; antennomere III slightly curved; antennomeres IV-XI becoming progressively shorter.
Pronotum subcylindrical, slightly wider at base, transverse, about 1.5 times as wide as long, sides irregular, with a small, acute protuberance each side behind middle ( Fig. 3d View Figure 3 ); lateral margins of pronotum with an elevated, arcuate ridge extending from acute protuberance to procoxal cavities; disk with three tubercles, median tubercle moderate-sized, oval, glabrous, very feebly elevated, adjacent to basal transverse sulcus, lateral tubercles larger, feebly elevated; entire disk microsculptured.
Scutellum transverse, apex rounded.
Elytra about 1.5 times as long as width at humeri ( Fig. 3a View Figure 3 ), about 3.5 times as long as pronotal length, about 1.4 times broader basally than pronotum at widest (at middle); sides slightly sinuous, feebly attenuate to apices, elytral apices individually rounded; base of each elytron with a prominent, broad gibbosity; basal 1/3 of elytra with dense, shallow punctation; humeri prominent, anterior margins arcu- ate, angles with several round, shiny tubercles extending along arcuate, strongly elevated cristae which extend to gibbosities ( Fig. 3 View Figure 3 a-b).
Venter with procoxae moderate, globose, not uncate; narrowest area of prosternal process between procoxae about 1/3 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; mesosternal process moderately emarginate at apex. Fifth sternite about 2 times as long as IV, apex feebly emarginate, with a median triangular impression.
Legs moderate to short in length; femora clavate apically; tibiae slightly expanded apically; metafemora about 1/3-1/4 as long as elytra.
Male. Length 14.0- 15.5 mm (measured from vertex to elytral apices), width 6.0- 6.5 mm (measured across humeri). Similar to female except frons elongate, about 1.5 times width of lower eye lobe. Antennal tubercles prominent. Antennae slightly longer than body. Basal 1/3 of scape with underside transversely rugose. Narrowest area of prosternal process between procoxae about 1/4 times as wide as procoxal cavity. Profemora transversely rugose. Fifth sternite about 1.5 times as long as IV, without a median triangular impression.
Type Material. Holotype, female ( Fig. 3 View Figure 3 a-d), “ Ecuador: Napo Pr., vic. Puerto Misahuali , 1650-1900 ft., 6-19-IX-1998 J. Eger coll., 1°2’4.2”S lat, 77°39’49.2”W lon” ( CASC) GoogleMaps . Allotype, male, “ PERU: CU, La Convencion, Echarate, CC. Pomareni, 72 o 50’8.89”/ 12 o 15’28.38” 477 m. 07.xi,2009. Light. C. Carranza y C. Rossi ” ( MUSM). One paratype, male, “ ECUADOR: Napo Pr., Jatun Sacha Reserve , 15 April 1999, F. T. Hovore, I.P. Swift, coll.” ( ENPC) .
Etymology. The specific epithet “cristata,” Latin for “crest” refers to the prominent, longitudinal crista at the base of each elytron.
Diagnosis and Remarks. The combination of the following characters will help to distinguish this genus and species: large eyes; distinct glabrous area at center of pronotal disk; and strongly elevated crest to basal 1/3 of elytra. This species is described from three specimens: two male and one female. Nothing is known about the habitat and behavior of this species; however, all three specimens were collected above 450 m elevation.
