Pseudestoloides bingkirki sp. nov.

( Figs 103–108 )

Description. Female. Integument black except yellowish brown distal area of palpomeres.

Head. Frons coarsely, partially confluent punctate; nearly glabrous laterally and toward clypeus, with yellowish brown pubescence centrally toward area between antennal tubercles; with a few short, erect, yellow setae close to base of antennal tubercles. Area between antennal tubercles and upper eye lobes coarsely, partially confluently punctate (punctures slightly coarser than on frons); with yellowish brown pubescence along median groove (this area narrowed toward upper eye lobes and fused with that along median groove on remaining surface of vertex) and near to upper eye lobes (this pubescence following toward area behind eyes and joins that on sides of vertex); area adjacent to upper eye lobes with narrow pale yellow pubescent band; area between yellowish brown pubescent bands on vertex nearly glabrous; with long, erect, pale yellow setae throughout. Area behind upper eye lobes coarsely punctate toward vertex, densely micropunctate toward lower eye lobes; with narrow pale yellow pubescent band adjacent to eye, gradually yellowish brown toward lower eye lobes; remaining surface with yellowish brown pubescence partially obscuring integument. Area behind lower eye lobes tumid and with yellowish brown pubescence partially obscuring integument close to eye, glabrous on remaining surface, densely micropunctate on band close to tumid area, smooth toward prothorax; with long, erect, sparse pale yellow setae on tumid area. Antennal tubercles coarsely punctate on frontal base, distinctly finer and sparser on remaining surface; with yellowish brown pubescence on some areas of base, nearly glabrous toward apex. Dorsal surface of head entirely densely micropunctate between coarse punctures (more distinctly on frons). Median groove distinct from clypeus to prothoracic margin. Genae moderately coarsely, sparsely punctate on central area, nearly smooth on remaining surface; with yellowish brown pubescence exposing integument, glabrous toward apex on dorsal area. Gulamentum smooth, glabrous on wide area close to prothorax, with transverse, wide, smooth, moderately elevated carina at base of submentum, and another wide, moderately elevated, punctate area close to mentum; submentum with sparse yellowish brown pubescence, with long, erect, dark setae interspersed laterally. Distance between upper eye lobes 0.75 times length of scape; in frontal view, distance between lower eye lobes 1.15 times length of scape. Antennae 1.5 times elytral length, reaching elytral apex at middle of antennomere X. Scape subclavate, slightly depressed dorsally on basal half; moderately coarsely, abundantly punctate on dorsal depressed area (punctures coarser toward base), finely, sparsely punctate on remaining surface; with pale yellowish brown pubescence exposing integument, with long, erect yellow setae interspersed throughout. Antennomeres III–IV with yellowish brown pubescence not obscuring integument; remaining antennomeres with yellowish white pubescence partially obscuring integument except for basal white pubescent ring; antennomeres III–XI with long, erect yellow setae ventrally, gradually shorter and sparser toward XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.64; pedicel = 0.10; IV = 0.79; V = 0.51; VI = 0.47; VII = 0.45; VIII = 0.39; IX = 0.37; X = 0.33; XI = 0.32.

Thorax. Prothorax, maximum width 1.55 times wider than long (including lateral tubercles); lateral tubercles large, long, with apex acute and pointed downward. Pronotum with longitudinal, slightly elevated central gibbosity; coarsely, moderately abundantly punctate except smooth central gibbosity and narrow distal area; with yellowish brown pubescence partially obscuring integument on some areas, sparse or nearly smooth on others (possibly rubbed or worn away), with short, sparse, erect yellow setae interspersed. Sides of prothorax nearly smooth on base and wide, oblique area from procoxal cavity to distal margin; remaining surface coarsely, moderately abundantly punctate; with yellowish brown pubescence, on some areas, slightly obscuring integument. Prosternum finely, moderately sparsely punctate on basal third, finely, transversely striate on central third, nearly smooth on distal third; with yellowish brown pubescence partially obscuring integument on basal third (less so centrally), sparsely pubescent on remaining surface. Prosternal process tumid centrally (more distinctly toward apex); with short, moderately sparse bristly pale yellow setae. Mesoventrite with yellowish white pubescence exposing integument centrally, slightly denser laterally. Mesanepisternum and mesepimeron with yellowish brown pubescence partially obscuring integument. Mesoventral process strongly tuberculate (tubercle deeply notched posteriorly), almost vertical toward mesoventrite. Metanepisternum and sides of metaventrite with yellowish brown pubescence partially obscuring integument; wide central triangular area of metaventrite nearly glabrous, except for short, sparse erect setae. Scutellum smooth, glabrous. Elytra. Coarsely, moderately sparsely punctate (especially toward apex); slightly longitudinally carinate on distal 2/3 near suture; with yellowish brown pubescence partially obscuring integument on some areas, sparse or nearly glabrous on others (possibly rubbed or worn away); with minute, sparse yellow setae emerging from some punctures; apices together rounded. Legs. Femora with yellowish brown pubescence partially obscuring integument on some areas (especially dorsally).

Abdomen. Ventrites with yellowish brown pubescence partially obscuring integument, except wide central area on ventrites I–IV, interspersed with long, erect, sparse yellow setae; sides of ventrites finely, sparsely punctate, coarser and slightly more abundant toward V. Ventrite V depressed on center of distal quarter; apex truncate, centrally emarginate.

Dimensions (mm). Total length, 18.20; prothoracic length, 3.15; basal prothoracic width, 3.96; distal prothoracic width, 3.37; maximum prothoracic width (between apices of lateral tubercles), 4.95; humeral width, 5.70; elytral length, 12.80.

Type material. Holotype female from NICARAGUA, Nueva Segovia: Cerro Jesus (13º58’N / 86º10’W; 1,300 m), 14.V.2016, E. van den Berghe col. ( FSCA).

Etymology. Named for Bing Kirk, hospitable owner of the coffee plantation (Cerro Jesus) where this new species was collected by Eric van den Berghe.

Remarks. Pseudestoloides bingkirki sp. nov. differs from the other species in the genus by the mesoventral process with a notably elevated tubercle which is deeply notched posteriorly ( Fig. 105 ). In other Pseudestoloides species, the mesoventral process tubercle is only slightly elevated and not notched posteriorly ( Fig 46 ).
