Japanagromyza incisa Sasakawa View in CoL
Japanagromyza incisa Sasakawa, 1963a: 28 View in CoL .
Japanagromyza howensis Spencer, 1977a: 115 View in CoL . syn. nov.
Remarks. This species is characterized by the entirely yellow halter, a long ultimate section of CuA1 (4/5 as long as the penultimate), a long hypandrial apodeme (as long as sidepiece), and a pair of campanulate distal tubules of the distiphallus.
Japanagromyza howensis Spencer was described from Lord Howe Is., Australia. It is clear that howensis is quite identical with incisa by the body color, and diagnostic character of the male genitalia in both species ( Sasakawa 1963a: Fig. 4a–c; Spencer 1977: Figs. 178–180); this new synonymy is established herewith. Distribution. Thailand, Australia.
Japanagromyza intricata sp. nov. ( Figs. 17–20 View FIGURES 14 – 20 )
Diagnosis. This species has the shiny black thorax and abdomen, yellow knob of the halter, and extremely long hypandrial apodeme.
Description. MALE. Black; parafrontalia shiny; antenna with scape and pedicel brown tinged; mesoscutm shiny, abdomen strongly shiny. Wing with calypter yellowish, margin brown, and fringe black; halter with stalk pale brown, knob yellow. Fore tarsus brown tinged.
Frons almost as wide as eye; eye 1.3 times as high as broad; gena 1/13 as high as eye (first antennal flagellomere and arista missing).
Mesoscutum with 10 rows of acr, short prsc. Wing 2.2 mm long; r-m almost at basal 1/3 of discal cell, ultimate section of CuA1 1/2 as long as penultimate. Fore tibia with lateral bristle.
S6 deeply incised at middle of posterior 2/3. Genitalia: Epandrium with a tooth and two spine-like setae at middle of inner anterior margin; cercus almost as high as epandrium, broadened ventrally; surstylus narrowed ventrally, bearing five or six spines apically; hypandrium 780 µm long, with basal apodeme about three times as long as sidepiece; phallapodeme 760 µm long; phallus 910 µm long, basiphallus short, hypophallus consists of six small sclerites on both sides, distiphallus with two long tubules, microscopically spinulose on membrane between basiphallus and distiphallic tubules; ejaculatory apodeme rod-like, 270 µm long.
Body length 2.3 mm.
FEMALE and HOSTPLANT. Unknown.
Type Material. Holotype 3 ( BPBM 17134), Malaysia, Sarawak, Sarikei District, Rejang Delta, 15–25. VII. 1958, T.C. Maa. Paratype: 3, same data as holotype ( BPBM).
Distribution. Malaysia ( Sarawak).
Remarks. Yellow knob of the halter and two distiphallic tubules of this species are similar to those of Japanagromyza stylata and J. hymenoedemia sp. nov., but from both of which this species may be distinguished by its conical surstylus with some more distal spines, more complicated hypophallus, and longer basal apodeme of the hypandrium. Diagnostic character of the hypophallus in this species is somewhat similar to that of J. perplexa Spencer , but perplexa has only three hypophallic sclerites in addition to the variegated knob of the halter, and shorter hypandrial apodeme.
Etymology. The specific name refers to the complicated (Latin: intricatus) sclerites of the hypophallus.
