Rhopalum (Latrorhopalum) creutzburgi View in CoL spec. nov.

: Body length 9.5–10 mm. Black, pronotal lobe yellow, inner side and rear of foretibia and foretarsus brown. Mandible black, with two teeth apically. Scape (identically with antennal segment 1) black, almost with little brown spots basally and apically. Antennal segment 2 black. Underside of antennal segment 3–12 brownish yellow. Last antennal segment black and flattened. Antennal segments not otherwise modified. Thorax and pronotum densely pitted, weakly shiny. Mesopleuron and propodeum with short white setae. Remaining thorax with fine white pubescence. Clypeus with dense silver setae covering sculpture. Front of clypeus produced in the middle, with two teeth close together, laterally with small angles often covered by dense setae (Fig. 2). Front edges of pronotum acuminate. Pronotum with weak medial impression, without transverse carina. Mesonotum apically with short, sometimes indistinct longitudinal keels. Propodeal enclosure not limited by groove or carina, with short keels basally. Vertical part of propodeum with deep central furrow. Petiolus with strong longitudinal keel before it widens. Abdominal tergites with very fine microscopic pits and short greyish pubescence. Sternites 2–6 with spots of white setae apically. Foretarsomere 1 curved, weakly broadened apically (Fig. 3), innerside with a row of short spines. Forefemora with round impression inside. Midtibia with brown spot distally in front of the spur. Midtarsomere 1 mostly yellowish white, sometimes black, produced in a brownish spine apically (Fig. 4). Hindtibia strongly clubbed. Hindtarsomere 1 weakly curved, tarsomere 2 normal. Legs except tarsi with short white pubescence. Spines outside of the tibia of all legs very short and inconspicuous. Relation between length of the marginal cell on radius and maximal breath of marginal cell 1.8–2.2 (cf. Fig. 6, 8). Habitus Figs 23, 24.

: 10 mm. Black, pronotal lobe yellow or nearly black, inner side of foretibia and last tarsomere brown. Mandible black. Front of clypeus medially produced with two strong teeth, laterally with distinct angles (Fig. 1). Teeth of clypeus stronger than in male. Antenna black; antennal segments 5–11, sometimes base of antennal segment 12, underside brown. Pygidial plate smooth, lustrous, without pits, lateral keels straight, with short longitudinal keel basally. Sternites 2–5 with white setal tufts. Forefemora with round impression inside. Petiolus 4.5x as long as maximal width. Remaining sculpture and pubescence similar to male. Relation between length of marginal cell on radius and maximal breath of marginal cell 1.8–2.2 (cf. Fig. 6, 8). Habitus Figs 25, 26.

Etymology: The species is named in honour of Frank Creutzburg, the collector of the type specimens.
