Ommata (Chariergodes) turrialbae Giesbert, 1991: 388 (part; remarks).

Diagnosis. Chariergodes Zajciw (1963) is a small genus containing just four species. Three of these, C. anceps (Melzer, 1927) , C. carinicollis (Zajciw, 1963) , and C. flava (Zajciw, 1963) are primarily orange species, with or without dark appendages, and recorded only from southeastern Brazil. The fourth is C. turrialbae ( Giesbert, 1991) from Costa Rica. Chariergodes lingafelteri can be readily separated from the latter by the basal fifth of elytra reddish, and the surface punctation in this area finer, shallower and more widely separated than those on the rest of the elytra (coarser, deeper and most contiguous). In C. turrialbae the elytra is uniformly metallic green with its surface punctation similar throughout (moderately fine, shallow and most not contiguous).

According to Giesbert (1991): “An additional small series of specimens, provisionally assignable to this species, have been seen from 35 km E. Cañitas, Panamá prov., PANAMA, June 7, 1984 (R. Penrose, F. Hovore). These are not considered paratypes because they differ from the typical O. turrialbae by the dull reddish basal quarter of the elytra, a color pattern resembling that of O. beltiana Bates. ” Although, these specimens should be in either the Frank Hovore collection, now housed at the CASC, or the Richard Penrose collection, now housed at the CA Department of Food and Agriculture, they have not been located in either collection. Nonetheless, based on Giesberts’ comments they are very likely examples of the new species.

Description. Integument shining metallic green (antennomeres gradually opaque towards apex of antenna), with slightly violaceous reflexions, except for basal 1/5, or slightly more, of elytra reddish, palpi brown on basal 2/3, yellowish on distal 1/3.

Head. Not elongated behind eyes (posterior edge of eyes close to anterior edge of prothorax); rostrum (between apex of lower eye lobe and genal apex), in frontal view, shorter than length of lower eye. Frons coarsely, confluently punctate from clypeus to antennal tubercles; narrow carina on each side from clypeus to base of antennal tubercles; area bordering coronal suture elevated; with moderately sparse, short setae, slightly denser close to the eye margin and around coronal suture. Vertex coarsely, confluently punctate; with sparse, short setae, sparsely interspersed with long setae. Antennal tubercles coarsely punctate on front portion of basal 1/2, moderately finely punctate on rear portion of basal 1/2, gradually finer towards apex; apex narrowly smooth. Clypeus abundantly, coarsely punctate on basal 2/3, smooth on distal 1/3; punctate area with sparse, short setae and one long seta on each side. Outer surface of mandibles sparsely, finely punctate; with sparse, short setae, sparsely interspersed with long setae. Area behind lower eye lobes striate-punctate; with sparse, long setae close to eye. Genae abundantly, moderately finely punctate, gradually smoother towards apex; with sparse, short setae. Gula smooth, shining and glabrous. Submentum obliquely striate; sparsely, moderately finely punctate; with sparse, long setae. Distance between upper eye lobes 0.6 times length of scape; distance, in frontal view, between lower eye lobes 0.75 times length of scape. Antennae 2.0 times elytral length; surpassing elytral apices at basal third of antennomere VIII; scape sparsely, finely punctate, distinctly sparser towards apex; antennal formula (ratio) based on antennomere III: scape = 0.66; pedicel = 0.18; IV = 0.88; V = 1.22; VI = 1.46; VII = 1.40; VIII = 1.04; IX = 1.02; X = 0.82; XI = 0.82.

Thorax. Prothorax subcylindrical, longer than wide; sides rounded, enlarged near middle. Pronotum longitudinally carinate centrally; densely, coarsely punctate; longitudinal carina transversely striate from middle to basal 1/4; basal 1/5 pubescent, interspersed with long setae; remaining surface with moderately abundant, long setae. Sides of prothorax abundantly, coarsely punctate on superior 1/2, sparser, finely punctate on inferior 1/2; pubescent, sparsely interspersed with long setae. Prosternum abundantly, coarsely punctate on basal 1/2; anterior 1/2 transversely striate, with sparse, coarse punctures; abundant, long setae on basal 1/2, gradually sparser towards anterior margin. Prosternal process narrowed at middle, notably enlarged triangularly towards apex (triangular area concave). Metepisterna moderately abundantly, coarsely punctate; with abundant, short setae, interspersed with long setae. Metasternum abundantly, coarsely punctate laterally, gradually finer and sparser towards middle; with moderately abundant, short setae, interspersed with long setae. Scutellum pubescent.

Elytra. Each elytron with longitudinal lateral carina, from near humeri to about distal 1/5, indistinct on basal reddish area; reddish area moderately finely punctate, with moderately abundant, long setae; metallic green portion more coarsely punctate, with sparse short setae, sparsely interspersed with long setae (gradually sparser towards apex); apex subrounded, with narrow pubescent area. Legs. Slender, femora with moderately abundant, short setae, interspersed with long setae. Protibiae with dense pubescence on lateral and ventral sides, with moderately long setae dorsally; meso- and metatibiae with long, thick setae.

Abdomen. Ventrites microsculptured, sparsely, finely punctate, except for smooth area at apex of ventrites I–IV; with abundant, short pubescence (not obscuring integument), interspersed with sparse, long setae.

Dimensions in mm (female). Total length (from mandibular apex to abdominal apex), 10.7; prothorax: length, 1.9; anterior width, 1.3; posterior width, 1.4; humeral width, 1.8; elytral length, 6.3.

Type material. Holotype female from PANAMA, Panama: 25 KM SE Cañita, 6-7.V.1999, Wappes & Morris col. ( FSCA) . Paratypes (5) – PANAMA, Panama: Bayano Dist. , 1 female, 28-41 km E. Canitas, 24.V.1984, F. Hovore coll. ( CASC) ; 1 female, 3.VI.1984, F. Hovore coll. ( CASC) ; Ipeti , 1 female, 11.V.1985, F. Hovore coll. ( CASC) ; COSTA RICA, Guanacaste: Santa Rosa N. P., 2 females, 10.VI.2002, F. Hovore coll. (1 ACMT, 1 MZSP) .

Etymology. Named for Steven W. Lingafelter (USDA, Plant Protection and Quarantine, Douglas, Arizona), a valued friend, serious student of and prolific publisher on all things Cerambycidae , who takes on projects, big or small, with the same competitive zest doing an outstanding job on each.
