Description of Male Holotype.—Length of body 3.2 mm.

Head.— 1.2 times as long as wide, moderately squared in dorsal aspect, weakly narrowing behind and broadly rounded towards occipital carina. The distance from the eyes to the occipital carina ca. 1.25 times the length of the eyes in dorsal aspect. Ocellar triangle forms a slightly obtuse angle at the anterior ocellus. The distance between lateral and anteriomedian ocelli is equal to the maximum diameter of the latter. Occipital carina from hind ocelli at a distance of 1.5 times of the maximum diameter of the latter. Surface of head finely coriaceous with sparse punctures.

Length-to-width ratios of antennomeres: scape: 3.1, pedicel: 1.6, 1st flagellomere: 1.7, 5th flagellomere: 1.5. Terminal palpomere of maxillary palps over 4 times longer than wide.

Mesosoma.— With a length-to-depth ratio of 3.2 and length-to-width ratio of 2.3. Pronotum elongate and narrow anteriorly, with a narrow horizontal shelf protruding above base of propleuron. Length-to-width ratio of propodeal disc 1.2. Radius with a node/vestigial vein in its basal 1/7. Metcarpus missing. Fore femur swollen, with a length-to-width ratio of ca. 2.1. Hind trochanter with a large ventral tooth. Hind femur flattened beneath, with a large basal tooth on the inner edge, a small tooth centrally and a median swelling on the outer lateroventral edge.

Metasoma.—Eighth sternite with distal margin centrally with a shallow emargination, centrally with long setae. Subgenital plate with distal margin centrally deeply emarginate, with long setae centrally and along distal margin.

Male genitalia.— Distal part of parameres densely covered with long setae. Volsellae with digitus not clearly visible. Volsellae with an additional seta just basad of cuspis. Aedeagus as illustrated.

Colour.— Brown. Basal three antennomeres, palps, mandibles, tarsi and tibiae yellow.

Etymology.— Named after Thomas Coker of Rockbridge Baths, Virginia, U.S.A.
