Estoloides morrisi sp. nov.

( Figs 118–123 )

Description. Male ( Figs 118–122 ). Integument dark brown, almost black on some areas.

Head. Frons and vertex coarsely, abundantly punctate; with light ochraceous pubescence partially obscuring integument; on frons, with short, suberect, moderately abundant pale yellow setae throughout, and a few long, erect brownish setae close to lower eye lobes; on vertex, with long, erect pale yellow setae, especially laterally. With fringe of short, dense pale ochraceous pubescence surrounding eyes. Area behind upper eye lobes coarsely, moderately abundantly punctate on area close to eyes, distinctly finer toward prothorax; with ochraceous pubescence, denser close to fringe surrounding eye, slightly sparser toward prothorax. Area behind lower eye lobes finely, moderately sparsely punctate close to eyes, transverse band with minute, dense punctures centrally, finely, sparsely punctate toward prothorax, especially toward ventral side; with ochraceous pubescence close to eyes, slightly denser close to fringe surrounding eye, glabrous toward prothorax (this latter area widened toward ventral side of head); with long, erect, sparse pale yellow setae close to eye. Antennal tubercles finely, densely punctate, less so toward upper eye lobe; pubescence as on frons, with a few long pale yellow setae interspersed. Median groove distinct on vertex, only indicated on frons. Genae very finely, abundantly punctate except nearly smooth area close to apex; with ochraceous pubescence partially obscuring integument, except glabrous, narrow distal area; with a few long, erect pale yellow setae. Gulamentum smooth and glabrous except on depressed area close to mentum with ochraceous pubescence interspersed with a few long, erect, brownish setae. Labrum finely, moderately abundantly punctate, coarser close to base of inclined area; with ochraceous pubescence distinctly exposing integument on basal half, with short and long, erect pale yellow setae on distal half (longer laterally). Distance between upper eye lobes 0.42 times length of scape (2.37 times width of one lobe); in frontal view, distance between lower eye lobes 0.84 times length of scape. Antennae 2.6 times elytral length, reaching elytral apex near apex of antennomere VII. Scape gradually widened toward apex, without strong curvature on basal third of inner side; densely, minutely punctate; with ochraceous pubescence partially obscuring integument, with long, erect pale yellow setae interspersed (longer and more abundant ventrally). Antennomeres III–XI with long, erect pale yellow setae, gradually sparser, shorter toward XI; antennomeres IV–XI with grayish white pubescent basal ring, and remaining surface with light ochraceous pubescence, sparser on distal area. Antennal formula (ratio) based on length of antennomere III: scape = 0.61; pedicel = 0.11; IV = 1.01; V = 0.83; VI = 0.81; VII = 0.75; VIII = 0.68; IX = 0.67; X = 0.60; XI = 0.75.

Thorax. Prothorax, maximum width 1.4 times wider than long (including lateral tubercles); lateral tubercles large, placed at middle, with apex acute. Pronotum with 3 low, slightly distinct gibbosities, one more distinct, subelliptical, placed centrally (its apex slightly surpassing middle of pronotum), two oblique, less distinct, placed on each side of central gibbosity; coarsely, abundantly punctate except smooth central gibbosity; with ochraceous pubescence partially obscuring integument, with sparse, short and long pale yellow setae interspersed. Sides of prothorax coarsely, moderately abundant punctate on wide central area, nearly smooth basally and distally; with ochraceous pubescence partially obscuring integument. Prosternum coarsely, moderately abundantly punctate close to procoxal cavities, very finely, obliquely striate, less so centrally, except on nearly smooth distal area; with ochraceous pubescence not obscuring integument. Prosternal process longitudinally, widely, slightly sulcate centrally; basal area coarsely, moderately sparsely punctate, finer, denser toward distal area; with ochraceous pubescence partially obscuring integument (somewhat bristly). Ventral side of meso- and metathorax with light ochraceous pubescence partially obscuring integument, slightly sparser toward center of metaventrite, forming small, subcircular, nearly glabrous areas laterally on metaventrite. Scutellum with dense, yellow pubescence except central area with sparser pubescence. Elytra. Coarsely, abundantly punctate throughout; with light ochraceous pubescence irregularly denser on some areas, but distinctly exposing punctures, with short, moderately abundant, suberect brownish setae interspersed; apices individually rounded. Legs. Femora with light ochraceous pubescence partially obscuring integument, except glabrous, small areas exposing shallow punctures.

Abdomen. Ventrites with light ochraceous pubescence partially obscuring integument, except glabrous, small areas exposing shallow punctures, and distal area of ventrites I–IV with fringe of yellower pubescence; ventrites I– IV with sparse, long, erect pale yellow setae; ventrite V with long, erect, pale yellow setae moderately abundant on distal half; apex of ventrite V truncate.

Female ( Fig. 123 ). Differs from male by the wider body, shorter antennae (1.6 times elytral length, reaching elytral apex near middle of antennomere IX), and central area of abdominal ventrite V depressed distally, with its distal margin centrally emarginate.

Dimensions (mm), holotype male/ paratype males/ paratype females. Total length, 14.17/10.03–13.63/ 10.30–15.57; prothoracic length, 2.65/1.84–2.56/1.71–2.70; basal prothoracic width, 2.97/2.02–2.83/2.02–3.19; distal prothoracic width, 2.65/1.95–2.56/1.93–2.92; maximum prothoracic width (between apices of lateral tubercles), 3.73/2.63–3.64/2.61–4.27; humeral width, 4.45/3.19–4.32/3.10–5.04; elytral length, 9.94/7.04–9.76/ 7.56–11.47.

Type material. Holotype male from MEXICO, Nayarit: Volcan Ceborunco (4–12 km W Jala), 27.IX.1991, Morris, Wappes, Giesbert col. ( FSCA) . Paratypes – 1 male, 2 females, same data as holotype ( RFMC) . Nayarit: 5– 10 km W Jala (4000–5000’), 12 males, 4 females, 27.IX–6.X.1991, Giesbert col. (10 males, 2 females, FSCA; 1 male, 1 female, MZSP, 1 male, 1 female ACMT)) . Jalisco: 2 km W Atenquique (4200’), 1 male, 22.VII.1995, J. Rifkind col. ( FSCA) .

Etymology. Named for Roy F. Morris II, outstanding cerambycid collector, and collector of the holotype and several paratypes of this new species.

Remarks. Estoloides morrisi sp. nov. is similar to E. noguerai , but differs as follows: distance between upper eye lobes ( Fig. 122 ) smaller (in male about 2.35 times width of one lobe; in female 2.60 times width of one lobe); antennae in male longer (2.6 times elytral length); scape uniformly and gradually widened toward apex at inner side ( Fig. 122 ). In E. noguerai , the distance between upper eye lobes ( Fig. 124 ) is larger (in male about 3.10 times width of one lobe; in female about 3.7 times width of one lobe); antennae in male shorter (about 2.2 times elytral length); scape more strongly widened after basal third ( Fig. 124 ).
