Nova Guinea. Holotype : male , missing, not examined (see ‘remarks’) . Material examined. 1 female ( RMNH ), NEW GUINEA [= Indonesia : Papua ]: Bernhard Camp 50 m , J. Olthof coll., October 1938 ; 1 female ( RMNH ): NEW GUINEA : Araucaria Camp 800 m , L. J. Toxopeus coll., 15 March 1939 ; 1 male ( NHMUK ), ‘ NEW GUINEA’ ( NHMUK010880763 ) ; 1 male ( NHMUK ), ‘ NEW GUINEA’ , labelled as ‘ male homotype Morley det. ii.1914 ’, September 1911 , ( NHMUK010880763 ) ; 1 female ( NHMUK ), PAPUA NEW GUINEA , Morobe , Wau , 1000 m , I.D. Gauld coll., October 1979 ( NHMUK010880762 ) . Diagnosis. Body reddish, except reddish brown last tergites; fore wing with apical third to half dark brown; scutellum with spine posteriorly; ovipositor sheath about 2.1 times as long as hind tibia. Description of female. Head. Antennawith 37 flagellomeres in one intact specimen, first flagellomere 3.3× longer than width, 1.2× length of second; frons evenly punctate, setose; face 0.5× as high as wide; clypeus separated from face by impression, about 0.55× as high as wide; malar space short, about 0.2× mandibular basal width; interocellar distance about 0.2× ocellar-ocular distance. Mesosoma. Epomia strong, sinuous posteriorly, 1.2× as long as mandibular basal width; scutellum densely punctate, setose, posteriorly with short spine/projection medially; mesopleuron subpolished, with fine, sparse punctures, sternaulus strong, extending to posterior margin, epicnemial carina present, extending to anterior margin; propodeum with posterior transverse carina straight across posterior of area superomedia, posteriorwidth of area superomedia about 1.2× as long as anterior width, spiracle round, closer to lateral longitudinal carina than to anterior transverse carina; fore basitarsus 0.9× as long as tarsomeres 2–5 combined; mid basitarsus slightly longer than tarsomeres 2–5 combined; hind basitarsus 1.1× tarsomeres 2–5 combined. Fore wing length 8.1–8.9 mm , vein M&RS opposite 1 cu-a , vein 2 rs-m about 0.9× 3 rs-m , vein 1 m-cu&M without ramulus, hind wing with first abscissa of vein CU about 1.2× vein cu-a ; distal ends of RS and M obsolete, present as traces. Metasoma. First tergite subpolished, about 6.0× as long as posterior width, laterally with long setae, spiracle at anterior 0.4; second tergite 0.8× as long as first tergite, 4.6× as long as anterior width, 1.8× as longas posterior width, anterolaterally with callus between anterior edge and spiracle; ovipositor sheath 2.1× as long as hind tibia. Colour. Reddish. Fore wing with dark brown area extending from apical to basal 0.4 of discosubmarginal cell medially, ventrally extending nearly to the claval notch or 2 cu -a , narrowly hyaline around veins comprising areolet and around bullae in 2 m-cu . Hind wing dark brown apically. Posterior metasomal tergites reddish brown. Male. Similar to female but dark brown part extends slightly further along the wings, to 2 cu-a . One male with antennae intact with 36 flagellomeres. Distribution. Currently known only from Papua ( Indonesia , Papua New Guinea ) ( Yu et al., 2012 ). Remarks. The identity of the specimens identified as C. pilosellus is uncertain. Asyntype (probably a holotype as there is no reason to suppose Cameron had more than one specimen when he described the species) is supposed to be in RMNH, transferred with the entomological collections from Amsterdam, but is missing. We base our interpretation of the species on Cameron’s (1911) original description and on a male specimen in NHMUK identified as Anunda pilosella by Claude Morley and labeled by Morley as a ‘homotype’ (Morley, 1914, unpublished data). This has no nomenclatural standing but by definition implies that Morley directly compared this male with the holotype or a syntype male. Cameron’s (1911) original description is not of the highest quality, being brief, without diagnosis and lacking illustrations, and does not mention a projection on the scutellum. However, the rest of the description, including the black markings on the fore wing, agrees. This is the first description of the female of C. pilosellus .
