Japanagromyza eucalypti Spencer

( Figs. 11–13 )

Japanagromyza eucalypti Spencer, 1963a: 309 .

Remarks. This is a leafminer of Eucalyptus camaldulensis Dehnhardt (Myrtaceae) in Australia. This species is readily recognizable by a pale knob of the halter, the yellowish brown tarsi, the elongate surstylus with an apical spine, the proctiger with a pair of long lateral processes, and the distiphallus with long tubule.

Spencer (1963a, 1977a) described briefly and illustrated roughly the long phallus (1963a: Fig. 1A), and the elongated epandrium and cercus (1977a: Fig. 174). His ‘distinctive epandrium’ means accurately both the elongate surstylus and process of the proctiger, and also his ‘distinctive ventral appendage’ consists of the hypophallus and paraphallus. Diagnostic character of the male genitalia is described here in detail: the surstylus has an apical spine; proctiger is well sclerotized, setulose on apices of long lateral processes; hypandrium is narrow U-shaped, 620 µm long, with short basal apodeme (140 µm long); phallapodeme is 740 µm long; phallus is 630 µm long; basiphallus with left sclerite distinctly longer than right one; hypophallus is narrow, right paraphallus is distinctly broader than the left; distiphallic tubule is approximately twice as long as basiphallus; ejaculatory apodeme is broadened asymmetrically, 255 µm long (not narrow as shown in Fig. 1B by Spencer, probably in lateral view).

Female genitalia: see Sasakawa 1996.
