Description.
FEMALE (
holotype
). Body length
8.5 mm
; LFW:
3.72 mm
.
Color
. Body black. Mandible, palpi, tip of clypeus, antennae castaneous. Metasomal segments black with castaneous borders. Leg bright castaneous with trochanter dark castaneous. Fore wing hyaline with veins light castaneous; stigma dark castaneous (
Fig. 1
).
Head
. Hairy, shining surface strongly punctate with punctures deep, close together, irregularly spaced. Mandible with long setae, three teeth progressing larger posteriorly to anteriorly; lowest tooth largest and sharpened; middle tooth smaller but still sharpened; upper tooth round. Clypeus flattened apically, emarginate, with sharp median ridge and long setae. Eye small, LH 2.6 × HE, with short, erect setae. Ratios of antennomeres 4:1.4:1.5:1.3:1.2:1.2:1.2:1.2:1.1:1.1:1.0:1.1:1.8. LH 1.0 × WH, HE 1.0 × OOL, WF 2.28 × WOT, POL 1.2 × AOL.
Mesosoma
. Pronotal disc 0.6 × as long as wide, sculptured in same manner as head. Mesoscutum coriaceous, 1.5 × length of mesoscutellum with punctures only on posterior half; notaulus narrow anteriorly and divergent, broadening posteriorly and converging, each notaulus separated by 1.1 × posterior width. Mesoscutellum coriaceous with punctures and setae on lateral edges; scutellar pit large, subrectangular, each pit separated by 0.1 × width and slanting from center posteriorly towards lateral margin. Dorsal view of metapectal-propodeal complex 0.67 × as long as wide, strongly reticulated on shining surface; metapostnotal median carina and each metapostnotal propodeal suture reaching transverse posterior carina; strong paraspiracular carina present; posterolateral corner foveolate. Fore wing with transverse-median vein strongly arched, convex posteriorly, but not meeting anal vein.
Metasoma
. Petiolate and smooth; T3–T7 with sparse punctures, sparse pale setae.
Remarks.
Epyris loisae
sp. nov.
differs most obviously from
E. fulvimanus
in the sculpturing of the propodeum. In
E. fulvimanus
,
the propodeum is smooth, as opposed to being strongly reticulate in
E. loisae
.
Additionally, the posterolateral corners are strongly foveolate in
E. loisae
. Finally, in
E. fulvimanus
, only the tibia is castaneous, and the mesoscutum in
E. loisae
is much longer, 1.5 × the length of the mesoscutellum as opposed to being equal length in
E. fulvimanus
.
Etymology
. The species name is in memoriam to Lois Tribull, the author’s mother.
