Description.

Female. Body length: 1.28 - 1.60 mm (n=9). Antenna color: A1 lighter in color than remainder of dark brown antennomeres. Body color: completely dark brown. Coxae color: dark brown. Leg color (excluding coxae): yellow. Fore wing color: completely hyaline.

Head. Size of compound eye: approximately 1/2 × height of head. Head shape in lateral view: lower head elongate and broad at mouth, head appearing elongate and somewhat thin. Sculpture of antennal scrobe: largely smooth ventrally, dorsally with sinuate, transverse ridges.Surface of torular triangle: flat. Development of central keel on frons: present, elongate, reaching anterior ocellus. Sculpture on upper frons below anterior ocellus: with sparse, transverse costae mixed with weak, dense granulae. Sculpture of malar space: with fan-like striae, striae extending into antennal scrobe. Furrow at lateral portion of antennal scrobe: present. Mesal surface of vertex: flat to weakly convex. Size of lateral ocelli: large. Distance between lateral ocellus and occipital carina: 0.5 –1.2× maximum ocellar diameter. Lagrimal: absent or minute. Length of OOL: less than or equal to 1/3 × width of ocellus. Sculpture of vertex: granulate. Sculpture of occipital carina: weakly crenulate throughout. Distance from occipital carina to orbital carina: at least 2 × width of occipital carina. Shape of occipital carina: simply arcuate medially. Sculpture of occiput: with weakly rugulo aciculate sculpture. Sculpture of gena: granulose.

Mesosoma. Dorsal mesosoma in lateral view: convex. Sculpture of pronotal cervical area: with small (at most as large as crenulae on anterior edge of mesoscutum), well-defined foveae. Sculpture of pronotal lateral area: upper 1/3 granulose, lower 1/3 with transverse foveae, otherwise smooth. Netrion: present, smooth, linear. Notaulus: present, simple. Length of notaulus: approximately less than or equal to 1/3 of length of mesoscutum. Width of notaulus: narrow (notaulus width less than or equal to half the width of tegula). Sculpture of mesoscutum: weakly rugulose mixed with weak granulae. Sculpture of mesoscutellum: granulose. Mesoscutellar profile: mainly flat, anterior and posterior edge at same height or nearly so. Mesoscutellar shape: flat, not depressed. Lateral propodeal area: coarsely rugulose. Shape of propodeal anterior spine: elongate, narrow, apex rounded. Sculpture of propodeum between anterior spines: smooth or largely smooth. Sculpture of ventral half of mesepisternum: smooth or nearly so. Sculpture of upper 1/4 of mesopleuron: densely longitudinally costate across half width. Metapleural sculpture: midtransverse area smooth, otherwise with cristate, longitudinal carinae.

Wings. Stigmal vein: present, elongate, narrow. Campaniform sensilla at distal area of stigmal vein: present.

Metasoma. Shape of T1 horn: broad, short. Sculpture of upper portion of T1 horn: longitudinally carinate. Sculpture of posterior portion of T1 horn: smooth. Lateral carinae on T2: present, poorly defined. Sculpture of T2: largely weakly coriaceous mixed with longitudinal costae, meson coriaceous. Sculpture of T3: anterior third weakly costate sublaterally, weakly coriaceous mesally, otherwise granulose. Sculpture of S3-S6: S3 weakly granulose, S4-S6 weakly, finely coriaceous. S2 anterior carina: present, cristate, uninterrupted.

Male. Unknown.

Diagnosis.

This is the only known species to have a furrow at the lateral areas of the antennal scrobes in combination with a completely dark brown body.

Etymology.

This species is named after our friend and colleague, hymenopterist Dr Mike Sharkey from the University of Kentucky. The epithet is a noun in the genitive case.

Comments.

The holotype is in perfect condition except for the left antenna which is detached from the body but glued to the point; the paratype specimens are in good condition.
