Description

Male (Fig. 6a, b, c). Length: 7-8mm. Head (Fig. 6b): parafrontal golden yellow tomentose; parafacial, face, gena and postorbit golden yellow tomentose; postgena silver tomentose; antenna black-brown; arista reddish brown basally, black apically; gena 0.17X eye height; 3 reclinate orbital bristles; 3 lower frontal bristles, below the level of the arista, lowest reaching level of first flagellomere; first flagellomere shorter than facial margin by length of pedicel. Thorax (Fig. 6a, c): dorsum gold tomentose with 4 distinct dorsal vittae visible presuturally, postsuturally all blurred together into a black smudge; scutellum black except along outer margin where it is gold tomentose; 3 strong katepisternal bristles; anepisternum gold tomentose with silver margins; anepimeron bearing gold tinge on anterior 1/3; 1 pair of discal scutellar bristles. Legs: black on all segments. Wings: smoky gray, bearing 2-3 short setulae at the base of R4+5. Abdomen (Fig. 6a): ST1+2 and T3 with light orange-brown ground color on sides; ST1+2 all black, mid-dorsal depression extending to margin of syntergite; anterior margins of T3 and T4 bearing gold tomentum over ⅓ of tergal surface; T5 with gold tomentum over 1/2 or more; T3 and T4 bearing 3 pairs of median discal bristles in addition to 1 pair of median marginal bristles; T5 bearing 2 rows of discal bristles, and 1 row of marginal bristles. Male terminalia (Fig. 7): sternite 5 with two prominent rounded lobes, flanking a wide U-shaped median cleft; posterior lobes 0.48X length of anterior plate; inner margin covered in dense tomentum, covering approximately half of the surface area of each lobe; posterior lobes bearing short stout bristles throughout; anterior plate bare, subequal in width to posterior lobes; cerci subtriangular in dorsal view, 1.5X as long as wide, separated along entire length; in lateral view cerci dorsally straight, apically rounded, each cercus appearing blunt and blade-like; postgonite parallel-sided and rounded at tip when viewed laterally, entire structure curving along midpoint giving it a rounded C shaped appearance; anterobasal heel slightly rounded, bearing few minute cilia; ventral sclerite of distiphallus linear along basal half, terminating in a strongly dilated and rounded apex; membranous acrophallus displaying a strongly angled apex when viewed laterally.

Female (Fig. 6d, e, f). Length: 5-6mm. As male, with the exception of the following characters: abdomen: abdominal tomentum silver-gray; abdomen ventrolaterally flattened, lacking discal bristles; mid-ventral portion of T3-T5 abdominal tergites with a row of strong stout spines.

Diagnosis

Vibrissina randycurtisi sp. n. can be differentiated from its congeners by the combination of the following traits: parafacial and parafrontal all gold; ground color of T5 black in both sexes; abdominal tomentum covering over 30% of ST1+2, T3, and T4; females bearing only 1 pair of marginal bristles on segments ST1+2 and T3, and a single row of marginal bristles on T4.

Etymology

Vibrissina randycurtisi sp. n. is dedicated to Mr. Randy Curtis of Arlington, Virginia in recognition of his seminal support in acquiring the land on which the INBio national biodiversity inventory collections grew and thrived since their founding in 1989, and still do, now as part of Museo Nacional de Costa Rica.

Distribution

Costa Rica, ACG, Prov. Guanacaste. Rain forest, in a dry-rain lowland intergrade at 280m.

Ecology

Hosts: reared seven times from the larvae of the sawfly Sericoceros gibbus (Klug) ( Argidae ), feeding on the leaves of Coccoloba tuerckheimii Donn. Sm. ( Polygonaceae ).
