Material examined.
Holotype. Indonesia • ♀ (on slide); East Java, Jalan Kandangan, Kasembon; 7.808S, 112.313E; 305 m a.s.l.; 14-Jul-2012; S. Schmidt leg.; screen-sweep net; MZB; specimen ID: BC- ZSM-HYM-20770-C04. Paratype. Indonesia • ♂ (on slide); East Java, Jalan Kandangan, Kasembon; 7.808S, 112.313E; 305 m a.s.l.; 14-Jul-2012; S. Schmidt leg.; screen-sweep net; MZB; specimen ID: BC- ZSM-HYM-20770-C11.
Diagnosis.
Head and body dark brown ( Fig. 1A, B View Figure 1 ), fore wing behind marginal vein with infuscation except hyaline area near posterior margin ( Fig. 1F View Figure 1 ). Antenna (in female) with 4 anelli ( Fig. 1H View Figure 1 ). Clava elongate, about 6.7 times as long as broad and 1.5 times as long as scape length ( Fig. 1E View Figure 1 ). Fore wing marginal fringe slightly longer than half the length of the wing disc ( Fig. 1F View Figure 1 ). Midtibial spur subequal in length to corresponding basitarsus ( Fig. 1C View Figure 1 ).
Description (female holotype).
Colour. Head and body dark brown ( Fig. 1A, B View Figure 1 ), legs brown with tarsi pale ( Fig. 1A View Figure 1 ), antenna brown ( Fig. 1E View Figure 1 ). Fore wing with brown infuscation behind marginal vein, leaving a hyaline area posteriorly in basal half of the infuscation ( Fig. 1F View Figure 1 ), and a brown longitudinal stripe in basal cell.
Morphology. Head 1.78 times as broad as frontovertex width ( Fig. 1B View Figure 1 ), frontovertex width slightly less than length of clava (0.84), distance from mouth margin to facial ridge 0.61 times head height. Antenna with 4 anelli, F4 longer than each of the preceding segments, clava 6.7 times as long as broad and 1.51 times as long as scape length, pedicel 0.45 times as long as scape length ( Fig. 1E View Figure 1 ). Midlobe of mesoscutum with 4 setae in anterior half and 6 setae in posterior half, scutellum with 7 setae along posterior margin. Fore wing 2.7 times as long as broad ( Fig. 1F View Figure 1 ), longest setae of marginal fringe 0.56 times as long as width of disc, seta M1 absent, M2b present. Mesofemur ventrally with 3 long spines ( Fig. 4D View Figure 4 ). Midtibial spur subequal in length to corresponding basitarsus ( Fig. 1C View Figure 1 ), the latter 0.55 times as long as midtibia. Ovipositor nearly twice as long as midtibia (1.82) and 1.29 times as long as hind tibia.
Male.
Colour and structure similar to female ( Fig. 2A, B View Figure 2 ), but antenna ( Fig. 2D View Figure 2 ) with 3 anelli and longer, clava 7.28 times as long as broad and 2.76 times as long as scape ( Fig. 2D View Figure 2 ). Setae of fore wing ( Fig. 2E View Figure 2 ) stouter than in female. Genitalia as in Fig. 2G View Figure 2 , phallobase with a pair of setae, digitus about 3 times as long as broad, strongly curved at apex.
Host.
Unknown.
Distribution.
Only known from the type locality near Malang, East Java, Indonesia.
Etymology.
The species is named after the island of Java.
DNA barcode data.
The species exhibits an intraspecific variation of 0.2% and a distance of 12.2% to the nearest neighbour species, C. sumatrensis sp. nov. (Suppl. material 1, Genbank Accession Numbers: MH407241, MH407242).
Remarks.
The species is similar to Chartocerus kerrichi (Agarwal) and C. sumatrensis sp. nov. but can be distinguished from the former by the longer clava (6.7 times as long as broad, compared to 4.5 times in kerrichi ), the longer fore wing marginal fringe (0.56 times as long as width of disc compared to 0.36-0.40 times in kerrichi ), and the longer midtibial spur (subequal in length to corresponding basitarsus whereas distinctly shorter in kerrichi ). From C. sumatrensis sp. nov. it can be separated by the shorter ovipositor (less than 2.0 times as long as midtibia, compared to 2.9 times in sumatrensis ) and the longer midtibial spur (subequal in length to corresponding basitarsus, compared to 0.7 times in sumatrensis ).
