Estoloides parva ( Bates, 1885)

( Figs 130–134 )

Estoloides (Parestoloides) parva Breuning, 1940: 76 ; Blackwelder, 1946: 601 (checklist); Breuning, 1963: 507 (cat.); 1974a: 62; Chemsak et al., 1992: 119 (checklist); Monné, 1994b: 41 (cat.); Monné & Giesbert, 1994: 220 (checklist); Monné, 2005: 406 (cat.); 2017: 355 (cat.).

Redescription. Female ( Figs 131–134 ). Integument mostly dark brown; mouthparts light reddish brown; scape dark reddish brown, antennomeres III–IV reddish brown on basal 2/3, brown on distal third; antennomeres V–XI with basal ring reddish brown (this area larger ventrally), brown on remaining surface; legs mostly dark reddish brown.

Head. Frons moderately finely, sparsely punctate; with ochraceous pubescence partially obscuring integument; with a few long, erect brownish setae close to lower eye lobes. Area between antennal tubercles and upper eye lobes with punctures slightly coarser than on frons, sparse laterally, absent centrally between upper eye lobes; with ochraceous pubescence nearly obscuring integument, but exposing punctures; with long, erect, yellowish setae close to upper eye lobes (shorter than on frons); remaining surface of vertex with a few punctures behind upper eye lobes, smooth toward prothorax; with ochraceous pubescence nearly obscuring integument. Area behind upper eye lobes with ochraceous pubescence nearly obscuring integument, gradually less so toward lower eye lobes. Area behind lower eye lobes minutely, sparsely punctate toward prothorax; with grayish yellow pubescence close to eye, glabrous on remaining surface; with long, erect yellowish setae close to eye. Antennal tubercles with pubescence as on frons, with a few long, erect brownish setae interspersed. Median groove distinct from clypeus to prothoracic margin. Genae with grayish yellow pubescence not obscuring integument, except glabrous distal area; with a few long, erect yellowish setae. Gulamentum smooth and glabrous except on narrow depressed area close to mentum with sparse grayish pubescence interspersed with a few long, erect yellowish setae. Labrum with ochraceous, sparse pubescence interspersed with long, erect ochraceous setae, especially laterally. Distance between upper eye lobes 0.7 times length of scape (2.8 times width of one lobe); in frontal view, distance between lower eye lobes 1.03 times length of scape. Antennae 1.46 times elytral length, reaching elytral apex at middle of antennomere XI. Scape distinctly widened laterally from base to at about middle; with ochraceous pubescence not obscuring integument, and with a few long, erect, yellowish setae interspersed ventrally at distal third. Antennomeres with ochraceous pubescence not obscuring integument, paler on basal light area of antennomeres V–XI; with long erect, yellowish setae on ventral side of antennomeres III–VIII, gradually shorter, sparser toward VIII (browner depending on angle of light source). Antennal formula (ratio) based on length of antennomere III: scape = 0.91; pedicel = 0.21; IV = 1.03; V = 0.75; VI = 0.65; VII = 0.60; VIII = 0.54; IX = 0.51; X = 0.45; XI = 0.48.

Thorax. Prothorax, maximum width 1.35 times wider than long (including lateral tubercles); lateral tubercles large, placed slightly before middle, with apex acute. Pronotum with 3 slightly distinct gibbosities, one subelliptical, placed centrally on basal half, one subcircular, placed on each side of distal half; coarsely, moderately abundantly and shallowly punctate except on smooth gibbosities; with ochraceous pubescence partially obscuring integument, but distinctly exposing punctures, grayish yellow laterally; with a few long, erect yellowish setae (browner depending on angle of light source). Sides of prothorax with punctures as on pronotum on wide central area, nearly smooth basally and distally; with grayish yellow pubescence not obscuring integument. Prosternum moderately coarsely, sparsely, shallowly punctate on basal half, nearly smooth on remaining surface; with grayish yellow pubescence not obscuring integument. Ventral side of meso- and metathorax with grayish yellow pubescence not obscuring integument. Scutellum semi-circular, with pale yellow pubescence entirely obscuring integument. Elytra. Coarsely, shallowly punctate, gradually sparser toward apex; with ochraceous pubescence nearly obscuring integument, but distinctly exposing punctures, part of them surrounded by glabrous, circular area; with moderately long, erect dark setae; apices individually rounded. Legs. Femora with grayish yellow pubescence not obscuring integument.

Abdomen. Ventrites with grayish yellow pubescence not obscuring integument; distal area of ventrite V depressed centrally; apex of ventrite V truncate.

Male ( Fig. 129 ). It differs from the female by having longer antennae (1.87 times elytral length, reaching elytral apex at distal third of antennomere VIII).

Variation. Integument mostly black; mouthparts mostly dark brown, almost black; scape, pedicel and antennomeres III–IV dark brown; antennomeres V–XI with dark reddish brown basal ring; legs dark brown; punctures between upper eyes lobes reaching median groove; pronotal punctures from shallow to moderately deep, from notably coarse to distinctly finer; pronotal pubescence not notably exposing punctures; scutellum from semicircular to triangular, with pubescence entirely covering surface or glabrous centrally; elytral punctures not sparser toward apex.

Dimensions (mm), male/female. Total length, 6.52–7.51/6.03–6.97; prothoracic length, 1.39–1.62/1.21–1.44; basal prothoracic width, 1.39–1.57/1.23–1.57; distal prothoracic width, 1.30–1.44/1.15–1.39; maximum prothoracic width (between apices of lateral tubercles), 1.80–2.07/1.64–1.95; humeral width, 1.95–2.25/1.73–2.16; elytral length, 4.50–5.13/3.82–4.86.

Material examined. PANAMA, Bocas del Toro: 11.7 km W Punta Peña, 1 male, 20.II.1999, R. Turnbow col. ( FSCA) . Colón: Palenque , 1 male, 14.II.1999, R. Turnbow col. ( FSCA) ; 1 male, 17.II.1999, R. Turnbow col. (FSCA); 20 km NE Portobelo , 17.II.1999, R. Turnbow col. ( MZSP) ; 2 females, 24.II.1999, Turnbow col. (FSCA; MZSP).

Remarks. Breuning (1940) briefly described Estoloides (Parestoloides) parva as follows (translated): “Close to perforata Bat. , but smaller, antennomere III slightly shorter than IV, only slightly longer than scape, vertex scarcely punctate, last two tarsomeres not reddish. Length: 5.5 mm; width: 1.5 mm.” Examination of the photograph of the holotype suggests it is a male. The scutellum of the holotype is distinctly triangular, while in the couple figured here ( Figs 130, 132 ) it is semi-circular. However, we also examined a male specimen with the scutellum as in the holotype, indicating it is a variable feature in this species. The elytral punctation is also variable in the specimens examined, being as in the holotype ( Fig. 132 ) or denser ( Fig. 130 ). The pronotal punctation also varies widely as it may be distinctly exposed by the pubescence ( Figs 130, 132 ) or not.
