Chartocerus kartiniae Polaszek & Schmidt sp. nov. Fig. 3 A–I View Figure 3

Material examined.

Holotype. Indonesia • ♀ (on slide); West Java, Mount Halimun-Salak National Park, waterfall; 6.71250S, 106.52305E; 1100 m a.s.l.; 18-Sept-2015; A. Polaszek leg.; screen-sweep net; MZB; specimens ID: DNA 1317.

Diagnosis.

Chartocerus kartiniae sp. nov. is unique among Signiphoridae and is provisionally placed in Chartocerus on a balance of genus-level characters. The female can be quickly diagnosed among all Chartocerus species by the following combination of characters: metanotum pale ( Fig. 3A View Figure 3 ); fore wing with discal seta ( Fig. 3C View Figure 3 ); antennal funicle 2-segmented ( Fig. 3I View Figure 3 ).

Description (female holotype).

Colour. Head and body dark brown ( Fig. 3A, B View Figure 3 ), with metanotum distinctly pale in contrast, legs pale brown with fore tibiae and all tarsi pale yellow ( Fig. 3F View Figure 3 ), antenna yellow-brown with radicle and scape paler ( Fig. 3E View Figure 3 ). Fore wing with brown infuscation centrally and on marginal vein ( Fig. 3C View Figure 3 ).

Morphology. Head 1.52 times as broad as frontovertex width ( Fig. 3B View Figure 3 ), frontovertex width 0.87 times length of clava. Antenna with only 5 antennomeres (excluding radicle); antenna with 2 anelli, clava 5.5 times as long as broad and 1.7 times as long as scape length, pedicel about 0.5 times as long as scape length ( Fig. 3E View Figure 3 ). Midlobe of mesoscutum with 7 setae in posterior half, scutellum with 7 setae along posterior margin. Propodeum with a suggestion of a lamelliform process on the median sclerite. Fore wing 2.8 times as long as broad ( Fig. 3C View Figure 3 ), longest setae of marginal fringe 0.78 times as long as width of disc, all marginal vein setae present, stigmal seta long; discal seta present. Foretibial spur bifid, without a comb ( Fig. 3I View Figure 3 ). Midtibial spur 0.9 times as long as corresponding basitarsus ( Fig. 3F View Figure 3 ), the latter 0.57 times as long as mid tibia. Mesofemur with four long spines anteroventrally. Ovipositor 2.0 times as long as mid tibia and 1.5 times as long as hind tibia.

Host.

Unknown.

Distribution.

Known only from the type locality at Mount Halimun, West Java, Indonesia.

Etymology.

The species is named after Raden Adjeng Kartini.

DNA barcode data.

No sequence data were available for analysis.

Remarks.

This species is unique for the genus, having only two funicle antennomeres, and a prominent discal seta on the fore wing. The pale metanotum is unusual (or possibly unique) among known species of Chartocerus (J.B. Woolley, pers. comm.). The foretibial spur is bifid and without a comb, supporting placement of the species in the genus Chartocerus . A full DNA barcode sequence could not be obtained for the single specimen, but analysis of an available DNA fragment suggests membership of the Chartocerus lineage (distant from Signiphora and Thysanus Walker), and a possible sister-group relationship to remaining Chartocerus for which DNA data are available.
