Description

Described from 4 males and 4 females. Length: male = 6-7mm; female = 5-6mm .

Head: (Fig. 4b, e) eye haired, with long ommatrichia about as long as combined width of 4-5 eye facets; eye approximately 0.9x head height; vertex width 0.13-0.15x head width in male, 0.22-0.24x head width in female; frontal vitta width 0.43-0.46x 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 of subequal length in male, whereas in the female the uppermost is large and well developed, 2x the length of the lowermost; ocellar setae small, poorly developed and proclinate; facial ridge bare; palpus yellowish, with dark brown-yellow base; distally haired; almost uniform in width.

Thorax: (Fig. 4a, c, d, f) dorsal vittae faintly visible presuturally as slightly darker stripes, virtually invisible postsuturally; postpronotum with 2 setae, usually with one additional small seta; two postsutural supra-alar setae (rarely only 1); katepisternum with 3 setae, ventromedial seta poorly developed, almost hair-like; scutellar discal setae absent; legs black; wing smoky gray, vein R1 dorsally bare, vein R4+5 dorsally with 3-4 setulae at base in male, and 5-6 setulae at base in female.

Abdomen: ground color of dorsal surface mostly black; T1+2 all black in ground color in dorsal view, and of yellow ground color ventrally in lateral view; T3 mostly yellow on anterior 3/4, black posteriorly; coloration of T3, in dorsal view, appearing as a black triangle on a yellow background; T4 yellow in ground color on 1/3-1/2 of lateral surface, appearing as entirely black in dorsal view; T5 entirely black; transverse bands of sparse white pollinosity 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. 5) sternite 5 with median cleft V-shaped, apical lobes bearing rounded apices, each with 1 long, well-developed seta, the longest seta at least 4x as long as the second longest; anterior margin of basal plate slightly concave; surstylus with small hairs on inner and outer surfaces; in lateral view, surstylus almost straight on basal 1/2 and convex on apical 1/2 of anterior margin, and very slightly concave along posterior margin; in lateral view, surstylus and cercus almost equal in length; cercus in lateral view bent, digitate, strongly concave on anterior surface, very slightly concave on postero-apical margin, and with a rounded tip; cercus truncate in lateral view, appearing like a slightly bent thumb; in posterior view, cerci narrowed on apical 1/3, length of upper lobes almost equal to medial section and longer than the apical cleft, basal section 1/3 longer than apical section; apical cleft well defined, with rounded tips directed medially.

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 glenriverai   can bedistinguished from E. cryptica   by the following characters: consistently having only two postsutural supra-alar setae; a less developed medial katepisternal seta; a more spatulate surstylus (visible in both lateral and posterior views); and a more curved, narrower anterior section of cercus (in posterior view). Additionally, the posterior section of the cercus in E. glenriverai   is almost equal in length to the length of both the anterior and medial sections combined. Erythromelana cryptica   was one of the few species for which a barcode was available among the previously described species; its sequence was also different from that of E. glenriverai   (Fig. 1) .

Etymology

Erythromelana glenriverai   is named in recognition of Glen Rivera Chaves for his contributions to the accounting team for Area de Conservación Guanacaste, the forest this fly lives in.

Distribution

Costa Rica, ACG, Alajuela and Guanacaste Provs., rain forest, 430-740m elevation.

Ecology

A parasitoid of Eois   Janzen49, E.   Janzen04, E.   Janzen236 and E. dibapha   (Schaus) ( Geometridae   ), which feed on four species of rain forest Piperaceae   .
