Redescription. Male ( Figs 29–32 ). Integument mostly dark brown; mouthparts reddish brown; antennomeres III– XI dark reddish brown; tibiae gradually dark reddish brown toward apex; tarsi mostly dark reddish brown.

Head. Frons and vertex densely micropunctate, with moderately coarse, abundant punctures interspersed, confluent along median groove near base of antennal tubercles, absent between upper eye lobes centrally, slightly sparser toward prothoracic margin; with abundant yellowish brown pubescence not obscuring coarser punctures, with long, erect setae close to lower eyes (yellowish brown close to lower eye lobes, yellow close to upper eye lobes). Area behind upper eye lobes, close to eye, moderately coarsely sparsely punctate, densely punctate toward prothorax; with yellowish brown pubescence partially obscuring integument. Area behind lower eye lobes tumid close to eye; coarsely punctate on tumid area, abundantly micropunctate adjacent to tumid area, gradually smooth toward prothorax and ventral side; with narrow, yellowish white pubescent band close to eye, pale yellowish brown on remaining tumid area, nearly glabrous toward prothorax; with long, erect yellow setae close to eye. Antennal tubercles abundantly micropunctate on frontal area, gradually sparser toward upper eye lobes; with yellowish brown pubescence partially obscuring integument. Median groove distinct from clypeus to prothoracic margin. Genae finely, transversely striate on basal half, with some coarse punctures interspersed, densely micropunctate toward apex; with narrow yellowish white pubescent band close to eye, pubescence sparse, pale yellowish brown on remaining surface; with a few, long, erect yellow setae. Gulamentum shining, smooth, glabrous on wide basal area, slightly rugose, with pale yellowish brown pubescence, close to mentum, with long, erect yellowish brown setae interspersed. Labrum convex on basal 2/3, inclined on distal third; finely, smoothly punctate on basal third, moderately coarsely punctate on remaining surface; with long, moderately sparse yellow setae directed forward and fringe of yellowish brown setae at distal margin. Distance between upper eye lobes 0.40 times length of scape (2.00 times width of one lobe); in frontal view, distance between lower eye lobes 0.85 times length of scape. Antennae 2.3 times elytral length, reaching elytral apex near apex of antennomere VI. Scape abruptly widened internally near base; moderately coarsely, sparsely punctate, especially dorsally; with pale yellowish brown pubescence dorsally, gradually yellowish white toward ventral side, except small subcircular glabrous areas; with long, erect yellowish brown setae (longer ventrally). Antennomeres with pale yellowish brown pubescence except for white pubescent basal ring (wider, less distinct on III and IV); ventral side of antennomeres III–XI with long, erect yellow setae, gradually shorter, sparser toward XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.48; pedicel = 0.10; IV = 0.94; V = 0.56; VI = 0.49; VII = 0.46; VIII = 0.44; IX = 0.44; X = 0.41; XI = 0.52.

Thorax. Prothorax, maximum width 1.47 times wider than long (including lateral tubercles); lateral tubercles large, placed at middle, with apex acute, directed upward. Pronotum with five slightly distinct gibbosities, one elongate centrally, placed on basal half, one subcircular on each side of distal half, one on each side of middle (subfused with lateroanterior gibbosity); coarsely, moderately abundantly punctate, except on smooth central gibbosity and center longitudinal area along distal half; with yellowish brown pubescence partially obscuring integument, except sides (including lateral tubercles) with yellowish white pubescence; with long, erect, sparse yellow setae. Sides of prothorax with punctures as on pronotum, except nearly smooth basal area and wide, oblique area from procoxal cavity to distal margin; with yellowish white pubescence partially obscuring integument, with long, erect, sparse yellow setae interspersed. Prosternum moderately finely punctate close to procoxal cavities, nearly smooth on remaining surface; with white pubescence not obscuring integument. Prosternal process carinate centrally (carina widened toward apex); with white pubescence not obscuring integument. Sides of mesoventrite and mesanepisternum moderately finely, sparsely punctate; with white pubescence not obscuring integument. Metanepisternum and sides of metaventrite moderately finely, sparsely punctate; with grayish white pubescence partially obscuring integument, except glabrous area surrounding each puncture; remaining surface of metaventrite with white pubescence not obscuring integument. Scutellum with dense yellow pubescence. Elytra. Moderately finely, abundantly punctate on base, sparser, subaligned in rows toward apex; shallowly, longitudinally sulcate dorsally; with yellowish brown pubescence nearly obscuring integument, grayish white pubescent laterally; apex with long spine at outer angle, and sutural angle rounded and projected. Legs. Femora with grayish white pubescence partially obscuring integument, except small, moderately abundant, circular glabrous areas.

Abdomen. Ventrites with grayish white pubescence partially obscuring integument, except small, moderately abundant, circular glabrous areas laterally. Apex of ventrite V truncate (slightly concave).

Female ( Figs 33–36 ). Differs from male by the shorter antennae (1.5 times elytral length, reaching elytral apex at base of antennomere X), and center of distal third of abdominal ventrite V somewhat depressed.

Dimensions (mm) male/female. Total length, 15.25/15.97; prothoracic length, 2.92/2.79; basal prothoracic width, 3.37/3.51; distal prothoracic width, 2.92/2.97; maximum prothoracic width (between apices of lateral tubercles), 4.32/4.30; humeral width, 4.86/5.13; elytral length, 10.80/11.79.

Material examined. JAMAICA, Hardwar Gap (4000’), 1 male, 23.VII.1966, Howden & Becker col. ( MZSP) ; 1 female, 29.VII.1966, Howden & Becker col. (MZSP).

Remarks. Fisher (1942) described Ataxia monticola (Pteropliini) from Jamaica, and Breuning (1954) described Estoloides (Spinestoloides) spinipennis (Desmiphorini) , also from Jamaica. Subsequently, Breuning (1961b) transferred A. monticola to Esthlogena (Esthlogena) Thomson, 1864 (Pteropliini) . Actually, based on the original descriptions and photographs of the holotypes (see Bezark 2017), A. monticola and E. (S.) spinipennis are the same species and belong to Desmiphorini . The holotype of Ataxia monticola is a female, and although Breuning (1954, 1974a) had not remarked on the sex of E. (S.) spinipennis , the holotype is also a female (see Bezark 2017).
