Pseudagaone williamsi sp. nov.

( Figs 1–3 )

Etymology. This species is dedicated to Kevin Williams, Utah State University, who brought hundreds of unidentified cerambycids to the second author of this paper for identification.

Diagnosis. Pseudagaone williamsi sp. nov. differs from the other species of the genus mainly by the elytra being almost completely orange.

Female ( Fig. 1 ). Integument yellowish. The following black: distal third of head; distal third of clypeus; mandibles; palpi (except narrow area between each segment, that is brownish); dorsal surface of head behind eyes (the orange area almost reaches the prothorax between the eyes); antennal tubercles; scape, pedicel, antennomeres III–IV; antennomere V, except a small orange macula on middle of ventral surface; antennomeres VI–IX, except orange area on basal half of ventral surface, slightly prolonged on inner third; distal half of antennomeres X–XI; central macula on anterior third of pronotum (slightly expanded laterally along anterior edge, and emarginate posteriorly); macula at side of procoxal cavities, truncate at edge towards pronotum, elongated towards apex of prosternal process; oblique macula on basal half of metepisternum, prolonged on metasternum up to the edge near metacoxae; distal half of narrow area along longitudinal sulcus of metasternum; outer half of procoxae; superior half of mesocoxae; profemora, except large elliptical area on inner surface; mesofemora; dorsal surface of peduncle of metafemora ( Figs 2–3 ), except on basal fourth; metafemoral club, except a small orange area on middle of inner and outer surface of club; tibiae and tarsi; center-distal third of ventrite V. The following brown-reddish: nearly all basal two-thirds of head; distal half of epipleural margin.

Area between inferior edge of lower ocular lobe and apex of labrum equal to 1.7 times length of one lower lobe. Distance between lower ocular lobe equal to 0.7 times length of scape; distance between upper ocular lobes equal to 0.65 times length of scape. Ocular carinae well marked, oblique, prolonged towards base of clypeus. Dorsal surface of head coarsely, abundantly punctate; setae short, sparse. Hypostomal area very coarsely, confluently punctate (rugose general appearance); setae moderately long, sparse. Antennal length equal to 0.9 times elytral length; apex of antennomere XI almost reaches the base of posterior third of elytra.

Pronotum coarsely, abundantly, confluently punctate; disc with longitudinal gibbosity from apex of transversal basal depression to slightly behind middle; pubescence on basal transversal depression very short. Basal two-thirds of prosternum coarsely, shallowly, abundantly punctate; distal third finely, transversely striate. Apex of prosternal process wide, truncate (centrally slightly emarginate). Mesosternum, metasternum and metepisterna ( Fig. 3 ) with short, abundant setae. Scutellum laterally broadly emarginate; apex deeply emarginate, appearing lobe-like. Elytra coarsely, very abundantly punctate; divergence of distal sutural half of elytra not strong. Ventrites moderately coarsely, abundant punctate, mainly laterally; setae short, sparse, intermixed with some long setae.

Variation. Dorso-basal third of antennomeres VIII and IX orange; antennomeres X and XI almost wholly orange; macula at side of procoxal cavities irregularly margined at edge towards pronotum; macula at side of procoxal cavities elongated and fused with the dorsal macula of pronotum; central macula on anterior third of pronotum not posteriorly emarginated; distal half of epipleural margin blackish; longitudinal metasternal sulcus not blackish; inner surface of profemora almost entirely orange; inner and outer surface of mesofemoral club with orange area; nearly all inner surface of metafemoral club orange; metafemoral club dorsally black, laterally orange, and ventrally brown; ventrites with irregular brown areas; ventrites wholly brown; scutellum laterally not widely emarginate, and apex slightly emarginate.

Dimensions in mm (female). Total length, 10.8–12.5; prothorax: length, 2.3–2.5; anterior width, 1.7–1.9; posterior width, 2.0–2.3; humeral width, 2.5–3.0; elytral length, 4.4–8.2. The largest dimensions are those of holotype.

Type material. Holotype female from BRAZIL, Rondônia: 62 km SE Ariquemes, 5–16.XI.1996, W. J. Hanson col. ( USUL). Paratypes (all females, from same place as holotype)— 8–20.XI.1994, W. J. Hanson col. ( LGBC); 5–16.XI.1996, W. J. Hanson col. ( LGBC); 22–31.X.1997, W. J. Hanson col. ( MZSP); (near Rancho Grande farm), 1–17.XI.1997, B. K. Dozier col. ( ACMT).
