Description

Male. Unknown. Female (Fig. 5). Length: 5mm. Head (Fig. 5b): parafrontal, postorbit, parafacial, face, gena, and postgena gold tomentose; antenna black-brown; arista reddish brown; gena 0.25X eye height; 2 pairs of proclinate orbital bristles; frontal bristles not reaching below lower margin of pedicel; first flagellomere short of facial margin by 2X length of pedicel. Thorax (Fig. 5a, c): dorsum gold tomentose with 4 distinct dorsal vittae visible presuturally, postsuturally vittae smudging together, covering slightly over ½ of postsutural scutum; scutellum gold tomentose over posterior 1/2, up to insertion of scutellar discals; 1 pair of discal scutellar bristles; apical scutellars weak and convergent; 3 strong katepisternal bristles, with ventral katepisternal bristle appearing greatly reduced compared to other 2, but still well developed; anepisternum, anepimeron and katepisternum slightly gold tomentose. Legs: reddish brown on all segments. Wings: smoky gray, bearing 2 short setulae dorsally at the base of R4+5. Abdomen (Fig. 5a): ground color of abdomen dark brown-black overall; ST1+2 all black; mid-dorsal depression extending to margin of syntergite; anterior margin of T3, T4 and T5 bearing gold tomentum over more than ½ of tergal surface; ST1+2 bearing 1 pair of median marginal bristles; T4 and T5 each bearing 1 complete row of marginal bristles; T3 with 1 pair of median discal bristles; T3, T4, and T5 ventrolaterally flattened; mid-ventral portion of T3-T5 abdominal tergites with a row of strong stout spines.

Diagnosis

Vibrissina hallwachsorum sp. n. can be differentiated from its congeners by the combination of the following traits: parafacial and parafrontal gold; tergite 5 bearing all black ground color with silver tomentum over its entirety; and only 1 pair of discal bristles on T3.

Etymology

Vibrissina hallwachsorum sp. n. is dedicated to Robert and Marianne Hallwachs of Philadelphia, Pennsylvania in recognition of their seminal support in acquiring the buildings in which the INBio national biodiversity inventory collections have grown and thrived since 1989, and which are now donated to the Museo Nacional de Costa Rica.

Distribution

Costa Rica, ACG, Prov. Guanacaste, cloud forest, at 1090m.

Ecology

Hosts: reared once from a larva of the sawfly Waldheimia interstitialis (Cameron) ( Tenthredinidae ) feeding on the leaves of Hamelia patens Jacq. ( Rubiaceae ).
