Treatment

Genus Teloneria Aczél, 1954 View in CoL

Teloneria Aczél, 1954: 510 View in CoL .

Type species

Telostylinus apicalis Enderlein, 1922 (original designation) (= Telostylus apicatus Edwards, 1919 View in CoL ).

Remarks

The genus Teloneria is restituted from synonymy with Chaetonerius based on the following distinctive features: i) arista brown with pubescence shorter at base and longer towards apex; ii) inner process of pedicel positioned at dorsal half of inner surface, with broad linear shape and rounded apex; iii) antennal base shiny and small but well-developed, visible laterally between the anterior margin of frons and parafacial; iv) parafacial, genal and postocular areas very narrow, with the eye occupying a considerable part of its lateral surface; v) posterior fronto-orbital seta positioned at mid length of the eye; vi) three well-developed and long dorsocentral setae (one presutural and two postsutural), and vii) the exclusive character of wing vein A2, ending abruptly before reaching the second third of the anal lobe. As the species of Teloneria were associated with Chaetonerius and Telostylus in the past, we redescribe the genus and provide a key to clarify the separation between the newly restituted genus and these genera.

Redescription

Small species with very long setae. Tegument shiny; pruinescence, when present, sparse.

HEAD ( Fig. 1 View Fig A–B). Pedicel with one dorso-apical and one ventro-apical outstanding setae. Scape slightly longer than width. Anterior fronto-orbital seta positioned near anterior margin of fronto-orbital plate. Vertex and occiput joining in a curve that follows from close to posterior margin of eye until postgena. Parafacial and gena running very close to eye margin from genal seta towards antennal base. Postgena convex and narrow, with black setulae near occipital foramen.

THORAX ( Fig. 1 View Fig C–D). Thoracic setae conspicuously long, measuring 1.5̄2.0 times length of scutellum. Scapular seta absent. Postpronotal lobe as long as height and slightly protuberant. Scutellum sub-shiny and trapezoidal with rounded margins; apical scutellar seta slightly shorter than dorsocentral prescutellar seta. Anterior notopleural setae present. Katatergite slightly protruded. Katepisternum with one ventral seta. Basicosta with two setae. Femora cylindrical and conspicuously elongate. Anterior margin of mid femur with proximal row of 10̄14 setae. Tibiae with row of dorsal short setae.

ABDOMEN. Homogeneously colored. Syntergite 1+2 with short and numerous setae in anterior half, followed by a bare medial area and posteriorly; with longer setae in lower density. Sternite 6 capeshaped, laterally elongate and narrower near lateral margin of tergite 6. Syntergosternite 8 with 3̄5 long setae in proximal half of dorsal surface. Epandrium cylindrical and elongate, measuring approximately 1.5̄2.0 times length of syntergosternite 8; cercus and surstylus variable in length and shape ( Fig. 2 View Fig ); pregonite bare.
