Cerceris pseudoorangiae DOLLFUSS, 2025

Cerceris pseudoorangiae DOLLFUSS , nov.sp. ( Figs 21 View Figs 21 a-g)

Holotype: ♀, TANZANIA, Iringo Province, 50 km NW Iringo, 07°41'S 35°22'E, 1000 m, 7.I.2007, leg. J. Halada ( JHC). Paratype: 1♀, KENYA, Naro Moru, County Life Lodge, 6300', 25.XII.1969, leg. M.E. Irwin & E.S. Ross ( CAS).

E t y m o l o g y: The holotype is similar to Cerceris orangiae BRAUNS, 1926 .

R e c o g n i t i o n:Thefemaleof Cerceris pseudoorangiae has no longitudinal carina on coxa III, the apical margin of clypeus has six teeth and on the median area are two small tubercles near the apical margin ( Fig. 21a View Figs 21 ), the scutum is shiny with longitudinal rugae and punctures between the rugae, the mesopleuron has no tubercle and the epimeron no crest. Additionally, the propodeal enclosure is obliquely rugose anteriorly and transversely rugose posteriorly and the body length is 9-10 mm.

The female of C. orangiae BRAUNS is similar to C. pseudoorangiae but differs by having a tubercle on the mesopleuron and a vertical crest on the epinotum, much more ferruginous and yellow colour and the body length is larger (12-14 mm). The clypeus of C. xanthogaster ARNOLD is similar, but this species differs by having the mesopleuron with a tubercle and the rest of the body (except clypeus and frons) is ferruginous and black.

D e s c r i p t i o n: ♀, 9-10 mm. Sculpture: anterior margin of clypeus with six small teeth; median part of clypeus with two small tubercles near apical margin ( Fig. 21a View Figs 21 ); mandible without distinct tooth internally; pronotal collar rounded laterally; prosternum without transverse carina; mesopleuron without tubercle; epimeron without crest; propodeal enclosure anteriorly obliquely rugose, posteriorly transversely rugose and medio-longitudinal furrow not crenulate; petiole as long as wide ( Fig. 21e View Figs 21 ); coxa III without longitudinal carina; sternum II without basal plate; pygidial plate rounded apically ( Fig. 21d View Figs 21 ); flagellum as in Fig. 21c View Figs 21 . Puncturation: median area of clypeus shiny and nearly impunctate; clypeal side micro-punctate; frons micro-punctate and densely punctate; vertex densely rugose-punctate; pronotal collar densely punctate; prosternum and tegula impunctate; scutum longitudinally rugose and punctate between the rugae; scutellum similarly shaped; mesopleuron densely reticulate-punctate; terga densely punctate; pygidial plate basally punctate and apically irregularly finely structured. Pilosity: clypeal side and frons covered with short appressed setae; gena, mesopleuron, propodeal side and femora covered with sparse erect setae; rest of body covered with short irregular setae. Colouration: black; following parts yellow: median part of basal half of clypeus, lateral stripe on frons, inter-antennal carina, lateral spots on pronotal collar, anterior half of tegula, metanotum, petiole apical, tergum III apical half, terga IV and V small stripe apical, sternum II lateral, coxa III partly, mandible basally; following parts ferruginous: flagellum beneath, tegula posterior half, pygidial plate and legs (except coxae); wings hyaline, radial cell of forewing and apex fuscous.
