Description
(based on holotype). Adult male Body size: 10 mm.
Head. Face occupying slightly less than 1 / 3 of head width in frontal view; shiny black; white setulose, except narrow bare patch below antennae. Gena very narrow; black; white setulose. Oral margin laterally not produced. Frons black; medially bare, laterally black setulose. Vertex black; black setulose except for small patch of golden yellow setulae anteriorly and a few scattered golden yellow setulae posteriorly. Occiput black; dorsal 1 / 3 golden yellow setulose, otherwise white setulose. Eye bare. Antenna blackish brown; antennal ratio ~ 4: 1: 5.
Thorax. Scutum shiny black with clear green sheen; golden yellow setulose, except for small median patch of black setulae on anterior 1 / 3 and some scattered black setulae laterally posteriad of transverse suture. Postpronotum of same colour as scutum; golden yellow setulose. Postalar callus brown; yellow setulose with a few black setulae ventrolaterally. Scutellum trapezoid, with two calcars as long as ~ 1 / 4 of scutellar length; of same colour as scutum except calcars dull black; golden yellow setulose with a few black setulae posteriorly. Pleura shiny blackish brown. Anepisternum with shallow sulcus; golden yellow setulose anterodorsally, black setulose posterodorsally, widely bare medially and ventrally. Anepimeron golden yellow setulose with a few black setulae dorsally. Katepisternum with patch of pale yellow setulae dorsally and small patch of whitish setulae ventrally. Katatergite long microtrichose, anatergite short microtrichose. Calypter and halter pale yellow.
Wing: hyaline; microtrichose, except bare on basal 1 / 8 of cell r 1 (along vein RS), most of cell br (only microtrichose along vena spuria), posterobasal 1 / 3 of cell bm, anterobasal 1 / 3 of cell cup, and basomedian 1 / 2 of alula.
Legs: femora and tibiae black, with tibiae a little brownish at both ends; tarsi brown, with apical tarsomeres paler than basal four tarsomeres. Femora black setulose, with ventrobasal patches of pale setulae. Tibiae black setulose anteriorly, white setulose posteriorly. Coxae and trochanters blackish brown; white setulose.
Abdomen. Tergites black. Tergite 1 yellow setulose, except black setulose near lateral margin. Tergite 2 golden yellow setulose, except for two large, bare, strongly metallic green shiny maculae, and black setulose along posterior half of lateral margin. Tergite 3 on most of surface with a mixture of short erect golden yellow and black setula; golden yellow setulae along posterior and lateral margins longer and more appressed, resulting in a fascia along these margins. Tergite 4 mostly short appressed black setulose, but longer pale yellow to whitish setulose along lateral margins and on pair of large posterior patches. Sternites blackish brown; sternite 1 bare; sternites 2 and 3 yellowish white setulose; sternite 4 black setulose. Genitalia as in Fig. 139 View Figures 138–141 .
Female. Unknown. The female listed under Additional material is included based on its COI barcode, but the specimen itself was not studied, as it was not possible for us to arrange a loan within the time frame of this study.
Diagnosis.
Body length: male 8–10 mm (n = 6). Superficially, this species looks most similar to S. boti Reemer , sp. nov., S. pallitarsis Reemer & Mengual , sp. nov. and S. varicaudata Reemer & Mengual , sp. nov., which are of similar size and colouration. These species also share the following combination of characters: face black, tibiae entirely brown, tergite 3 broadly dull with narrow shiny margins (Fig. 64 View Figures 64–68 ). However, this is the only known species of Serichlamys with a strong metallic green shine on scutum and scutellum (Figs 31 View Figures 30–35 , 64 View Figures 64–68 ). A weak metallic, sometimes green, shine also occurs in other species, but not as strong. In addition, there is a pair of large, smooth, metallic green maculae on tergite 2 (Fig. 31 View Figures 30–35 ) (these maculae are not green in the three species mentioned above).
Etymology.
The specific epithet is composed of the Greek words chloros (green) and aspis (shield). This name refers to the metallic green scutum and scutellum of this species.
Molecular data.
The holotype male was successfully sequenced and its DNA barcode clusters together (BS = 100) with the COI sequence of one of the paratypes ( MZH S 264), which had previously been identified as ‘ Microdon CR 99-10 ’ in GenBank, and a public sequence of another Serichlamys specimen from Costa Rica, previously identified as Microdon MRC- 20. Both codes or name-holders are known to be used by F. C. Thompson and likely refer to the same species, S. chloraspis Reemer , sp. nov.
Distribution.
This species is only known from Costa Rica, where it was found in the centre and southeast of the country at elevations between 50 and 1200 meters.
