(Figures 1 a-d)  
 Description. Male. Length 8.0-14.0 mm (measured from vertex to elytral apices), width 2.6-5.0 mm (measured across humeri). Habitus as in Fig. 1a. General form elongate-oblong, small to moderate-sized. Integument brown to ferrugineous with brown, ochraceous, and testaceous pubescence; portions of head, pronotum, scutellum, and venter with white pubescence; basal portions of antennomeres III-XI distinctly paler than apices; apical 1/5 of elytra distinctly darker, with irregularly-shaped testaceous maculae against a field of dark brown pubescence.   
Head with frons elongate, about width of 1.5 lower eye lobes; surface deeply punctate (as in Fig. 1c). Eyes with lower lobes moderate-sized, oblong; narrowest area connecting upper and lower eye lobes about 3 ommatidia wide. Genae elongate, about as tall as lower eye lobes; genae with distinct, curved, glabrous sulcus extending from lower eye lobe to base of mandibles.  
Antennae nearly 3 times longer than body; antennal tubercles prominent, narrowly separated, contiguous at base; tubercles not armed at apex; scape clavate; antennomeres V-X slightly curved; antennomere XI sinuate. Antennal formula based on antennomere III: scape=0.73; II=0.1; III=1; IV=0.97; V=0.83; VI=0.76; VII=0.77; VIII=0.85; IX=1.03; X=1.16; XI=1.8.  
Pronotum subcylindrical, slightly transverse, sides feebly arcuate (Fig. 1a, d); disk with surface densely punctate, with relatively large, deep punctures; basal transverse sulcus shallow; base of disk with small, oval, glabrous region anterior to basal sulcus.  
Scutellum transverse, apex rounded.  
Elytra about 2.2 times as long as width at humeri (Fig. 1a), about 3.3 times as long as pronotal length, about 1.3 times broader basally than pronotum at widest (at middle); lateral margins nearly straight, sides roughly parallel, slightly attenuate, gradually rounded to apices at apical 1/3, apices jointly rounded; basal 1/2 with surface densely punctate, with relatively large, deep punctures; humeri slightly prominent, anterior margin arcuate.  
Venter with procoxae large, globose, not uncate; apex of prosternal process subtriangular. Mesosternal process about half as wide as mesocoxal cavity; mesosternal process moderately emarginate. Fifth abdominal sternite slightly longer than IV.  
Legs moderate in length; femora robust; metafemora clavate apically; tibiae slightly expanded apically; metafemora about 1/3 as long as elytra; tarsomere V slightly shorter than as I-IV combined.  
 Female. Length 10.0- 13.5 mm (measured from vertex to elytral apices), width 3.7-5.0 mm (measured across humeri). Similar to male except antennae nearly 2 times longer than body.

 Etymology. We are pleased to name this species in honor of Maria Helena M. Galileo, for her many contributions to the study of Neotropical Cerambycidae. The epithet is a noun in the genitive case.   
 Diagnosis and Remarks. This species is distinguished from its congeners by the combination of the following characters: body with ochraceous pubescence; pronotal disk and basal 1/2 of elytra with surface densely punctate, elytral surface with relatively large, deep punctures; genae with distinct, curved, glabrous sulcus extending from lower eye lobe to base of mandibles. Cylicasta mariahelenae is described from 24 specimens: 15 males and nine females.
