Description

Described from 2 males and 2 females. Length: male = 6mm; female = 5-6mm.

Head: (Fig. 2b, e) eye haired, with long ommatrichia about as long as combined width of 4-5 eye facets; eye approximately 0.9x head height; vertex 0.12-0.14x head width in male, 0.21-0.23x head width in female; frontal vitta 0.33-0.35x vertex width in male, 0.32-0.34x vertex width in female; first flagellomere black, reaching facial margin; fronto-orbital plate with 2 reclinate inner orbital setae, the lowermost large and well developed in contrast to the uppermost, which is small or reduced, almost hair-like (especially in the female); ocellar setae proclinate; facial ridge bare; palpus yellowish, with dark umber base, distally haired and almost uniform in width.

Thorax: (Fig. 2a, c, d, f) dorsal vittae faintly visible as slightly darker stripes, the inner pair longer and thinner than the outer pair; postpronotum with 2 setae, often with one additional small seta; three postsutural supra-alar setae; katepisternum with 3 setae, ventromedial seta less than 1/3 the length of anteroventral seta; scutellar discal setae absent; legs black; wing smoky gray, vein R1 dorsally bare, vein R4+5 dorsally with 3-4 setulae at base.

Abdomen: dorsal surface of abdomen mostly black in ground color; ventral margins of T1+2 and T3 yellow in ground color, the yellow extending to 3/4 of lateral surface of these tergites; T4 yellow in ground color on 1/3-1/2 of lateral surface; in dorsal view, both T3 and T4 black in ground color medially and yellow laterally; ground color of T5 entirely black; transverse bands of sparse white pollinosisty present on anterior 1/3-1/4 of T3 and T4 and on anterior 2/3 of T5; one pair of median marginal setae on T1+2 and T3; T4 and T5 with a full row of marginal setae; mid-dorsal depression of T1+2 not reaching median marginal setae.

Male terminalia: (Fig. 3) sternite 5 with median cleft V-shaped; apical lobes broadly pointed, each with 2-3 long, well-developed setae, the longest seta at least 2x as long as second longest; surstylus with small hairs on inner and outer surfaces; surstylus, in lateral view, almost straight on basal 1/2 and convex on apical 1/2 of anterior margin, and very slightly concave along posterior margin; surstylus and cercus almost equal in length in lateral view (Fig. 3b); cercus, in lateral view, bent, digitate, not strongly concave on anterior surface, very slightly concave on postero-apical margin, and with a rounded tip; in posterior view, cerci narrowed inapical 1/3, length of upper lobes almost equal to medial section and longer than the apical cleft; apical cleft well defined with rounded tips directed slightly medially, basal section 2/3 the length of apical section.

Diagnosis

This species is included in the E. cryptica species group ( Inclan and Stireman 2013) because of its morphological similarity to other members of the group. Erythromelana jimmychevezi can bedistinguished from E. arciforceps by the following character states: light brown wings; multiple, strong apical setae on the lobes of sternite 5; more pointed appearance to the apices of the lobes of sternite 5. It is worth noting that E. jimmychevezi may overlap in range with E. arciforceps , which has been collected from as far north as Monteverde, Costa Rica.

Etymology

Erythromelana jimmychevezi is named in recognition of Jimmy Chévez Elizondo for his contributions to the accounting team for Area de Conservación Guanacaste, the forest this fly lives in.

Distribution

Costa Rica, ACG, Guanacaste Prov., rain forest, 470-675 m elevation.

Ecology

A parasitoid of Eois Janzen52 ( Geometridae ), which feeds on Piper auritum ( Piperaceae ).
