Odontocera stangei Wappes and Santos-Silva , n. sp.

( Fig. 10–12 )

Diagnosis. Odontocera stangei is similar to O. armipes Zajciw, 1963 , but differs as follows: pronotum without clearly defined longitudinal black bands; each elytron with dark, oblique macula along base from humerus to suture. In O. armipes the pronotum has three longitudinal dark bands, and the elytra lack the dark, oblique macula. It differs from species with similar elytral patterns by the pronotum lacking areas of distinct, dense pubescence [ O. auropilosa Tippmann, 1953 ; O. barnouini Peñaherrera-Leiva and Tavakilian, 2003 ; O. beneluzi Peñaherrera-Leiva and Tavakilian, 2003 ; O. dice Newman, 1841 ; O. fasciata (Olivier, 1795) ; O. ornaticollis Bates, 1870 ; O. zeteki Fisher, 1930 ], or by the distinct coloring of the pronotal integument (without large lighter areas) [ O. buscki Fisher, 1930 ; O. compressipes White, 1855 ; O. darlingtoni Fisher, 1930 ; O. hirundipennis Zajciw, 1962 ].

Description. Integument primarily yellow orange with the following areas dark-brown or piceous to partially black: vertex; apex of mandibles; scape; pedicel; broadly triangular area under lower eye lobes, prolonged towards ventral surface on anterior margin of submentum; distal extreme of genae; pronotum, except for reddish-brown subreniform area on each side of basal 1/2, and oblique yellowish vitta laterally on basal 1/3 of prothorax; transverse vitta, interconnected to the dark area of pronotum, prolonged and narrowed towards ventral surface crossing the base of prosternal process; oblique vitta from humerus to elytral suture, extending laterally along the basal third of each elytron. The following lighter brown: antennomeres III–XI (opaque); gula, except for narrow longitudinal, yellowish central band; area of humerus interconnected to the oblique dark brown vitta, apex and elytral suture up to base of middle 1/3; lateral of mesosternum close to sides of mesosternal process; anterior margin of metepisterna; margin of metepisterna close to metasternum, from apex of basal 1/4 to apex; base of pro- and mesotibiae; parts of ventrites I–II; ventrites III–V. The following yellowish: frons and anterior 1/3 of prosternum.

Head. Not elongated behind eyes (posterior edge of eyes close to anterior edge of prothorax); rostrum (between apex of inferior ocular lobe and genal apex), in frontal view, 0.8 times length of lower eye lobe. Frons obliquely striate between inferior edge of lower eye lobes and clypeus; coarsely, shallowly punctate between lower eye lobes; with vitta of short setae from base of clypeus to base of antennal tubercle laterally, along inner edge of inferior ocular lobe; remaining surface glabrous. Vertex abundantly, coarsely punctate; with sparse, short setae. Clypeus with very short yellowish setae; with very long, dark, thick setae laterally. Labrum with sparse short setae, sparsely interspersed with long setae (with very long, thick setae laterally). Outer surface of mandible with sparse, short setae on base; one long seta on basal 1/3, and another on distal 1/3. Area behind lower eye lobes, near eye, fringed with dense yellowish white setae, sparsely interspersed with long setae; area under lower eye lobes with sparse, long brownish setae. Genae transversely striate near eyes, sparsely, finely punctate on remaining surface, except for narrow, shallow distal band; with sparse, short setae. Gula smooth, shining and glabrous. Submentum sparsely, coarsely punctate; with sparse, short setae. Distance between upper eye lobes 0.55 times length of scape; in frontal view, distance between lower lobes 0.50 times length of scape. Antennae 0.75 times elytral length; reaching near middle of elytra; antennomeres III–IV slightly enlarged towards apex, with outer angle distally rounded; antennomeres V–X distinctly enlarged towards apex, with outer angle dentate distally; antennal club not distinctly delimited; scape, pedicel, and antennomeres III–VI with moderately long, dark, thick setae; antennal formula (ratio) based on antennomere III: scape = 1.00; pedicel = 0.28; IV = 0.66; V = 0.71; VI = 0.71; VII = 0.71; VIII = 0.63; IX = 0.54; X = 0.48; XI = 0.57.

Thorax. Prothorax subcylindrical, slightly longer than wide, widest forward of middle, lacking lateral tubercles. Pronotum centrally elevated; callosities indistinct; coarsely, reticulate punctate; basal depression with short, rather inconspicuous setae; entire surface with moderately sparse, long, dark thick setae. Prothorax coarsely, reticulate punctate laterally (less so towards head); with sparse, mod- erately long setae, inconspicuously pubescent on basal half. Prosternum abundantly, coarsely, shallowly punctate and pubescent on basal half; distal 1/2 shining and somewhat glabrous. Prosternal process distinctly narrowed centrally, broadly enlarged towards apex; apex widely emarginate and truncate. Metepisterna abundantly, coarsely punctate on central 1/2; pubescent near elytra; remaining surface with sparse, short setae, interspersed with sparse, long setae on basal 1/3. Metasternum moderately sparsely, coarsely punctate laterally; with sparse, moderately long setae; small area near mesocoxae pubescent. Scutellum pubescent. Elytra. Narrowed from base to apex, dehiscent along suture for distal 1/2; abundantly, coarsely punctate on base and laterally; translucent area gradually depressed from base to apex, sparsely, finely, shallowly punctate; with sparse, moderately long setae on base, gradually sparser and shorter towards apex. Legs. Femora clavate; metafemora slightly longer than mesofemora; apex of metafemora reaching distal 1/3 of third abdominal segment. Metatarsomere I 1.1 times longer than II–III together.

Abdomen. Ventrites abundantly, moderately, finely punctate, mainly III and IV; pubescent laterally; remaining surface with moderately abundant, short setae, sparsely interspersed, with long setae.

Variation. Frons reddish-brown; ventrites I–II brown; ventrites III–V dark-brown; long setae of metepisterna present on entire surface.

Dimensions in mm (female). Total length (from mandibular apex to abdominal apex), 11.8–12.3; prothorax: length, 2.0–2.1; anterior width, 1.8–1.9; posterior width, 1.7–1.8; humeral width, 2.2–2.5; elytral length, 8.0–8.2. The largest dimensions are those of holotype.

Type material. Holotype female from VENEZUELA, Aragua: Rancho Grande , 4.VII.1988, L. Stange & C. Porter col. ( FSCA) . Paratype female, same data as holotype ( ACMT).

Etymology. This species is named for Lionel Stange, collector of the holotype and long time FSCA taxonomist and researcher (now retired). An avid collector, Lionel, has traveled extensively throughout tropical America with his friend Charley Porter, collecting a wide variety of insects. In the process they contributed many thousands of specimens to the FSCA collection including hundreds of tropical cerambycidae .
