Description.

Female. Unknown.

Male. Body length 3.35 mm (n=1).

Radicle color: darker than scape. Scape color: Brown. A5 tyloid: carina-like, not expanded. A11: longer than broad; as long as broad.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: without transverse or oblique carinae below submedian carina. Submedian carina: strong, formed by a sharp raised carina. Submedian carina medially: without peak. Median tooth of frontal depression: absent. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: hood-like, protruding over pedicel when antenna at rest. Malar area near antennal foramen: without carina or expansion. Malar area at mouth corner: with radiating striae. Smooth strip along posterior side of malar sulcus: absent or not consistently broad. Middle genal carina: present. Direction of middle genal carina dorsally: parallel to eye margin. Major sculpture of gena anteriorly: umbilicate-foveate. Major sculpture of gena posteriorly: umbilicate-foveate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. Median carina extending posteriorly from hyperoccipital carina: present. Hyperoccipital carina: complete, continuous with anterior genal carina. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: umbilicate-foveate. Occipital carina medially: convex, with a sharp median peak. Lateral corners of occipital carina: not protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: strong. Netrion surface anteriorly: not inflexed. Mesoscutum anteriorly: not steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-foveate; irregularly rugose. Major sculpture of medial mesoscutum poste riorly: umbilicate-foveate; irregularly rugose. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from rows of foveae. Number of carinae crossing speculum above femoral depression: 3. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: concave. Metascutellar sculpture dorsally: with scattered rugae. Median carina of metascutellum: absent or branched. Metascutellar setae: with many dorsal setae. Metascutellar apex: weakly emarginate. Metapleuron above ventral metapleural area: crossed by carinae. Metasomal depression setae: absent. Anterior areoles of metasomal depression: one or more areoles present. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: separated medially. Postmarginal vein: present.

Median lobe of T1: with 5 longitudinal carinae. Metasomal apex: with acuminate lateral corners.

Diagnosis.

Male: Frons without elevation between antennal foramen and eye. Frontal depression without tooth-like median protrusion dorsally. Hyperoccipital carina present, continuous with anterior genal carina; occipital carina complete medially and connected to hyperoccipital carina by a weak median carina. Metascutellum with dorsal setae. Metasomal depression elongate, with a single areole strongly defined by a posterior carina; lateral propodeal carinae narrowly separated anteriorly. T1 midlobe with 5 longitudinal carinae. T7 with sharp, narrowly protruding posterolateral corners.

Comments.

The type material of Camptoteleia crassicornis Kieffer, collected from Mount Makiling, Luzon, in the Philippines, could not be found after an extensive search of collections known to house Kieffer type material. The neotype of Camptoteleia crassicornis is presently designated to clarify the taxonomic status of the species. It was selected because it possesses a convex mesosoma and discernably posteriorly carinate head as specified by Kieffer (1916). This choice presumes that Kieffer (1916) overlooked the metascutellar setae and misinterpreted the postmarginal vein. However, no other examined Philippine specimens bear close resemblance to Kieffer’s description. Our concept of Oxyscelio crassicornis indicates that it is very close to Oxyscelio crustum .
