Sphecodes binghami Bluethgen, 1924 Figures 8-11

Sphecodes binghami Blüthgen, 1924: 497, ♀ (holotype: ♀, Myanmar, Pegu Hill, 3.89, coll. Bingham; NHMUK 010576231; examined).

Diagnosis.

The female of this species resembles Sphecodes takaensis Blüthgen, 1927 owing to a similar structure, sculpture and coloration of the body, but it differs from this species by the square F3 (as long as wide), the entirely areolate vertex and the wider pygidial plate which is as wide as metabasitarsus (in S. takaensis F3 0.7-0.8 times as long as wide; vertex with small shiny impunctate spots near ocelli; pygidial plate narrower than metabasitarsus).

Descriptive notes.

Wings with brownish darkening; hind wing with the angle between basal (M) and cubital (Cu) veins ca. 80°, costal margin with eight or nine hamuli. Lateral preoccipital carina present. Female. Total body length 8-9 mm. Head (Fig. 8 ) transverse, ca. 1.25 times as wide as long; vertex weakly elevated with distance from top of head to upper margin of lateral ocellus approximately a lateral ocellar diameter as seen in frontal view; labrum trapezoidal, 0.45 times as long as basal width; face and vertex areolate-punctate; paraocular (below and above the antennal sockets), supraclypeal areas and gena with adpressed white pubescence obscuring integument. Mesoscutum and mesoscutellum (Fig. 10 ) densely punctate (40-75 μm), medially with punctures separated by at most 1-2 puncture diameters, becoming confluent peripherally; propodeal triangle (metapostnotum) and mesepisternum (Fig. 9 ) reticulate-rugose. Metasoma red (Fig. 11 ); T1 on disc and marginal zone finely and densely punctate (10-15 μm / 0.5-3), remaining terga more coarsely punctate (10-25 μm) with impunctate and smooth marginal zones; pygidial plate dull, widely rounded apically, as wide as metabasitarsus. Male unknown.
