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

( Fig. 7–9 )

Diagnosis. Odontocera galileoae is similar to O. tibialis Zajciw, 1971 , but differs as follows: pronotum without black maculae; antennomeres not distinctly annulate; peduncle of metafemora and metatibiae unicolorous. In O. tibialis the pronotum often has a black macula on each side, the antennomeres are distinctly annulate, and the peduncle of metafemora and metatibiae are bicolorous. It is also similar to O. clara Bates, 1873 , differing as follows: head not entirely black; legs orange; lateral elytral vitta not reaching humerus. In O. clara the head is entirely black, the legs are primarily black, and the lateral elytral vitta is complete to the humerus.

Description. Integument pale orange. The following black: dorsal surface of head surrounding upper eye lobes; small macula close to and under lower eye lobes; distal 1/3 of mandibles; basal 1/2 of elytral suture. The following brownish: antennal tubercles; distal 1/2 of elytral suture; lateral vitta on elytra, from apex forward to and ending at basal 1/5; irregular area on each side of ventrites I, II, and IV, nearly all of III (angle of light source can cause ventrites to appear completely brown); tarsal claws. Antennomeres V–XI distally darker.

Head. Not elongated behind eyes (posterior edge of eyes close to anterior edge of prothorax); rostrum (between apex of lower eye lobes and genal apex), in frontal view, 0.45 times length of lower eye lobe. Frons yellowish white pubescent centrally, obscuring integument, distinctly sparser laterally, not obscuring integument. Vertex densely, moderately finely punctate; with abundant, short yellowish white setae, not obscuring integument, interspersed with sparse, long setae laterally. Antennal tubercles almost smooth, with sparse, short yellowish white setae, almost glabrous centrally. Clypeus with yellowish white pubescence medially at base, almost glabrous laterally and apically. Labrum with short pubescence, with sparse long setae on disc, one thick, long seta laterally; distal edge with brush of short setae. Outer surface of mandible with sparse, short setae, sparsely interspersed with long setae. Area behind and under lower eye lobes with sparse, long setae. Gena abundantly, moderately coarsely punctate on basal 2/3, smooth on distal 1/3; basal 2/3 with sparse, short setae, glabrous towards apex. Gula shining and glabrous. Submentum coarsely striate-punctate laterally, almost smooth centrally and distally; with sparse, short setae, distinctly longer laterally. Distance between upper eye lobes, in frontal view, 0.60 times length of scape; distance between lower eye lobes 0.15 times length of scape. Antennae 1.3 times elytral length; reaching base of distal 1/10 of elytra; antennomeres III–IV filiform; antennomere V enlarged towards apex, with outer angle distally rounded; antennomeres VI–X distinctly enlarged towards apex, with outer angle distally dentate; antennomeres VI–XI forming club, not distinctly delimited; scape, pedicel, and antennomeres III–VI with moderately long, dark, thick setae; antennal formula (ratio) based on antennomere III: scape = 0.65; pedicel = 0.20; IV = 0.57; V = 0.89; VI = 0.84; VII = 0.75; VIII = 0.65; IX = 0.60; X = 0.49; XI = 0.58.

Thorax. Prothorax subcylindrical, longer than wide, widest near middle, without lateral tubercles. Pronotum with longitudinal callosity on anterior 1/2 of disk, not reaching anterior edge; abundantly, coarsely punctate, mainly laterally, callosity smooth; basal depression with dense, short white setae; anterior 1/3 with abundant, short white setae (centrally sparser); remaining surface with sparse, moderately long, setae. Prothorax abundantly, coarsely punctate laterally; with dense, short white setae, except for subglabrous area close to anterior edge. Basal 2/3 of prosternum coarsely, striate-punctate, with moderately dense, short white pubescence, sparsely interspersed with long setae; distal 1/3 shining, striate, with sparse, short setae, mainly basally. Prosternal process distinctly narrowed centrally and broadly enlarged towards truncate apex. Metepisterna and metasternum with dense yellowish pubescence sparsely interspersed with long setae, except for glabrous area around distal 1/2 of metasternal suture. Scutellum with dense, yellowish white pubescence. Elytra. Narrowed from base to apex, slightly dehiscent along suture in distal half; abundantly, moderately coarsely punctate on basal 1/5 and laterally; translucent area sparsely, coarsely, shallowly punctate; with sparse long setae on basal 1/5, gradually sparser and shorter towards apex. Legs. Femora clavate; metafemoral peduncle distinctly long; apex of metafemora reaching abdominal apex. Metatarsomere I about as long as II–III together.

Abdomen. Ventrites with moderately short setae, denser laterally, sparsely interspersed with long setae; ventrite V elevated laterally and depressed centrally on distal 2/3.

Variation. Vertex black, with an orange diamond-shaped area between antennal tubercles; submentum black, except for narrow anterior band; submentum and nearly all gula black; basal 2/3 of mandibles brown; elytral suture, lateral and distal band of elytra black; base of metepisterna black; ventrites I–IV nearly all brown.

Dimensions in mm (male). Total length (from mandibular apex to abdominal apex), 12.20–12.40; prothorax: length, 2.30; anterior width, 1.60; posterior width, 1.75–1.80; humeral width, 2.10–2.15; elytral length, 7.60–7.90. The smallest dimensions are those of the holotype.

Type material. Holotype male from MEXICO, Guerrero: Hwy 200, 21 km N Ixtapa, 17–22.VII.1985, J. E. Wappes col. ( FSCA) . Paratypes – 2 males, same data as holotype ( ACMT, MZSP).

Etymology. We are pleased to name this species to honor and recognize our good friend and colleague, Maria Helena Mainieri Galileo for her numerous contributions to the knowledge of New World Ceram- bycidae. Publishing alone, or most often with her close friend Ubirajara Martins, she has researched and written more than 125 papers on Cerambycidae taxonomy. Her exceptional work continues today.
