Rosaphula handschini Frey, 1934: 303 View in CoL

Diagnosis. Basal part of flagellum short (rounded in m and short oval in ♀), pilosity of last flagellomere relatively short and apical style thus slender, almost rod-like, long apical seta distinct, tomentose frontal spots well developed. Scutum and scutellum black, only spines reddish yellow, wing with two separated darkened spots, legs reddish yellow including tarsi. Abdomen black, with extensive reddish brown median patch on tergites 2–4.

Description. Male ( Figs 27–29, 31–33 View FIGURES 22 – 32 View FIGURES 33 – 46 ). Length: body 5.2–5.7 mm, wing 5.3–6.0 mm. Head ( Fig. 33 View FIGURES 33 – 46 ) about 1.3 times higher than long in lateral view and about 1.4 times as wide as long in dorsal view. Upper frons very narrow, barely as long as ocellar triangle, lower frons small and subtriangular, covered by whitish tomentum except for tip. Antenna ( Fig. 32 View FIGURES 22 – 32 ) bright yellow, only last three flagellomeres black. Scape about 1.5 times longer than pedicel, basal flagellomeres widened, forming short oval basal part of flagellum. Apical style somewhat shifted dorsally, slender, with pilosity barely as broad as half width of pedicel at distal margin, with long apical seta occupying 1/5 of last flagellomere length. Last flagellomere (including apical seta) 2.3 times as long as rest of antenna. Narrow whitish lines along inner margin of eyes in facial area indistinct, confluent with short and sparse whitish hairs on surface of face. Basal segment of palpus and labellum of proboscis yellow, apical segment of palpus black.

Thorax predominantly shining black, only postpronotal callus, broad upper margin of anepisternum, postalar callus and posterior margin of scutellum including scutellar spines yellowish. Posterior margin of anepisternum and anepimeron brownish. Wing pattern of a bimaculate type but subapical spot diffuse and not too conspicuous. Halter yellow. Legs yellow, only fore tarsi darkened.

Abdomen elongate and slightly clavate, about twice as long as broad, black in ground colour but 3 basal abdominal segments with extensive yellow spots on both sides leaving only narrow midline and lateral margin darkened. Male terminalia ( Figs 27–29, 31 View FIGURES 22 – 32 ) brownish, proctiger pentagonal and cercus short, epandrium relatively narrow ( Fig. 27 View FIGURES 22 – 32 ), genital capsule with subtriangular medial process posteriorly and each gonocoxite with posteriorly oriented inner projection, gonostylus without inner spine ( Fig. 28 View FIGURES 22 – 32 ), spatulate in posterolateral view ( Fig. 31 View FIGURES 22 – 32 ). Aedeagal complex relatively short, with rod-like aedeagal apodeme ( Fig. 29 View FIGURES 22 – 32 ).

Female ( Fig. 66 View FIGURES 63 – 70 ). Length: body 5.4 mm, wing 5.2 mm. Head dichoptic, narrowest part of frons as wide as half width of ocellar triangle, lower frons above antennae with transverse whitish tomentose spot. Swollen basal part of flagellum short oval, larger than in male, last flagellomere (including apical seta) about 1.8 times as long as rest of antenna. Postocular area easily visible along posterior margin of eye in lateral view, as broad as pedicel is long. Pale areas of thorax reddish yellow or brown, pale margin of scutellum distinctly narrower than in male ( Fig. 66 View FIGURES 63 – 70 ). Wing and legs as in male, abdomen slightly broader at middle, 1.5 times as long as broad. Pale pattern confined to central areas of tergites 2 and 3 and occupying entire sternites 1–3. Female terminalia brownish.

Variation. In addition to some differences found between both sexes only slight variation among three examined males may be mentioned, e.g., the extent of the yellowish patches on the pleura and the abdomen.

Material examined. Type material: The female holotype from Java , Tjibodas Gedeh , deposited in NMB ( Woodley 2001) was not examined, but our four specimens perfectly fit the original description and also originated from the type locality. One female in BPBM is labelled "Compared with holotype Rosaphula handschini Frey, 1934: 303 , N. E. Woodley 2003" (see Other Material).

Other material: Indonesia: Java: Tjibodas, Mt. Gede, altitude 4500 ft, 1909 2 3, 1 ♀, Bryant & Palmer, (female with additional label: "Compared with holotype Rosaphula handschini Frey, 1934: 303 , N. E. Woodley 2003"; Tjibodas, 2.viii. 1965 1 3, J. Winkler, all in BPBM.

Distribution. Recorded only at Tjibodas on Java ( Indonesia) ( Fig.79 View FIGURE 79 ).
