(Figs 26–28)
Diagnosis. Acyphoderes violaceus sp. nov. is similar to A. cracentis Chemsak & Noguera 1997, but differs as follows: peduncle of the femora with dark-brown area; tibiae and metatarsi black with violaceous reflections. In A. cracentis the peduncles of the femora are wholly yellow, the basal half of the metatibiae is distinctly lighter than distal one, and the metatarsi are pale. Chemsak & Noguera (1997) did not discuss the color of metatibiae, and they recorded that the femora are reddish-brown. Examination of a photograph of an A. cracentis paratype indicates colors recorded above are correct. This species is also similar to Odontocera exilis Fisher, 1947, but clearly differs by the bicolored femora and black metatarsi. Odontocera exilis has the femora wholly black and metatarsi white.
Etymology. Acyphoderes violaceus is named for the reflective coloration of the pronotum legs and abdomen.
Female (Figs. 26–28)—Integument black with violaceous reflections. Femora reddish-brown, except the following dark-brown areas: dorsal surface of peduncle of profemora; distal half of mesofemora; distal 4/5 of peduncle of metafemora; extreme distal dorsal surface of all clavate portions of the femora. Each elytron with a longitudinal semi-translucent area from nearly base to distal fifth.
Head not elongated behind eyes (posterior edge of eyes near the anterior edge of prothorax); rostrum (between the apex of inferior ocular lobe and genal apex) about as long as length of inferior ocular lobe in frontal view. Dorsal surface of head finely, sparsely punctate, with some punctures coarser and shallower near clypeus; area between inferior ocular lobes with short, sparse setae; area between superior ocular lobes and prothorax with moderately long, sparse hairs. Clypeus with short, sparse setae, laterally with some longer setae. Labrum, with very sparse short setae, on each side with one long, thick seta. Outer surface of mandibles with one long, thick seta at base of distal third; remaining surface with short, sparse setae. Laterally, below inferior ocular lobes, with very long setae. Ventral surface of head moderately coarsely obliquely sulcate on hypostomal area, with moderately long, sparse setae. Eyes large, distinctly emarginate. Distance between inferior ocular lobes equal to length of one lobe in frontal view. Antennae slightly shorter than elytral length; antennomeres III–IV filiform; antennomeres V– XI serrated, slightly enlarged forming a club not well defined. Scape, pedicel, and antennomeres III–V with long, dark, thick setae (mainly pedicel and antennomere III).
Prothorax subcylindrical, elongate, slightly wider at middle, laterally without tubercles on this area. Pronotum with five tubercles (two on each side, and one central), well marked; disc with long, sparse setae, except on basal transverse depression, which is pubescent. Basal two-thirds of prosternum with abundant, long setae; distal third, shining, with sparse, long setae. Prosternal process strongly narrowed centrally, truncate at apex. Scutellum with short, abundant setae. Elytra long, narrow, reaching base of third abdominal segment, dehiscent along suture in distal half; surface with short sparse setae, slightly longer on base; area not translucent moderately finely, abundantly punctate. Mesepimeron pubescent. Mesosternal process strongly elevated at base. Mesepisterna visible in dorsal view near humerus. Metasternum tumid, with the central region distinctly more elevated than metacoxae. Metepisterna subtriangular (base distinctly wider than apex); with long, sparse setae, except on distal area, which is pubescent. Metasternum with moderately abundant, long setae. Ventrites with long, sparse setae, less so on ventrite I. Pronotal punctation coarse, moderately abundant.
Femora clavate; metafemoral peduncle distinctly long; apex of metafemora reaches apex of third abdominal segment. Metatarsomere I slender, 1.3 times longer than II–III together. Abdomen narrow, cylindrical, notably elongate, not curved downward.
Dimensions in mm (holotype female). Total length (from mandibular apex to abdominal apex), 16.8; prothorax: length, 2.5; anterior width, 1.9; posterior width, 1.9; humeral width, 2.3; elytral length, 8.3.
Type material. Holotype female from COSTA RICA, Guanacaste: 3 km SE R. Naranjo, VIII.1 –15.1993, F. D. Parker col. (USUL).
Remarks. Acyphoderes sensu auctorum encompasses more than one genus. The new species here described, without doubt, is not a true Acyphoderes. Although, we know that Robin O. S. Clarke (personal communication) is working on a revision of this genus, we do not know how long this will take. Thus, we are describing provisionally the species in Acyphoderes.
