Elaphropeza binotata ( de Meijere, 1911)

Drapetis binotata de Meijere, 1911: 333 (female).

Elaphropeza binotata: de Meijere, 1913: 74 (male).

Re-description. Female. Body length 2.0 mm, wing length 2.0 mm. Head with occiput black, shining. Antenna with scape and pedicel yellow, postpedicel dark brown. Palpus small, yellow.

Thorax almost entirely yellow, shining, with yellow to brownish yellow bristles; Scutum with large elongate subtriangular spot. Prothoracic episterna lacking long upturned bristle just above fore coxa, with short bristle in upper part. Postpronotal bristle minute. Mesonotum with 2 notopleural, 1 postsutural supra-alar, 1 postalar and 4 scutellar (inner ones very long, cruciate; outer ones very short) bristles. Acrostichal bristles 2- serial, lacking on prescutellar depression; dorsocentrals 1-serial, extending to base of scutellum, prescutellar pair long.

Legs long, slender, wholly yellow, with yellow to brownish yellow setation. Coxae and trochanters with unmodified setation. Fore femur with rows of short antero- and posteroventral bristles and 2 longer bristles near base. Fore tibia lacking prominent bristles (except subapicals). Mid femur with 2 rows of spinule-like, short, ventral bristles (becoming shorter in apical part of femur), 1 long thin bristle near base and 1 anterior subapical bristle. Mid tibia with ventral spinules, lacking prominent bristles (except subapicals). Hind femur bearing 1 row of short anteroventrals and 3–4 erect dorsal bristles near base. Hind tibia with 2 anterodorsal bristles in middle part; apical projection small, rounded, clothed in dense brownish setulae. Tarsi of all legs unmodified.

Wing normally developed, finely uniformly infuscate, covered with uniform microtrichia; veins yellowish to brownish yellow. Costal vein with moderately long setulae along anterior margin. Basal costal bristle moderately long, brownish. Costal index: 65/37/55/16. Vein Rs longer than crossvein bm-cu. Vein R2+3 smoothly arched, almost straight. Veins R4+5 and M1+2 parallel near wing apex, vein R4+5 slightly bowed. Vein CuA1 reaching wing margin. Vein A1 present as fold. Crossvein bm-cu somewhat oblique. Crossvein r-m before middle of cell bm. Halter with dark knob.

Abdomen with tergite 1 yellow. Tergites 2 and 3 brownish yellow; with unmodified setation. Tergite 4 broad, brown, subshining, with squamiform setae. Tergite 5 narrow, concolorous with tergite 4, bearing scattered unmodified setae. Tergites 6 and 7 concolorous with tergites 2 and 3. Segment 8 brown, rather short. Cercus brown. (Missing structures taken from de Meijere (1911)).

Type material examined. Holotype female labelled: [red label] Drapetis / binotata / de Meijere, 1911 / ZMAN type DIPT.0474.1; Drapetis binotata [hand-written] / det. de Meijere / Type [hand-written]; Java / Salatiga / Doct. v. Leeuwen ( ZMAN).

De Meijere (1911) described this species from a single female that is deposited in the ZMAN. Later, he mentioned the male of this species was taken from Batavia (de Meijere 1913), but we have not seen that material. Currently, the head and one wing are lost from the holotype; otherwise it is in good condition .

Distribution. Indonesia (Java).

Remarks. The relationships of E. binotata are unclear beyond inclusion within the E. ephippiata species group.
