ETYMOLOGY: Latin, flav -, prefix meaning yellow + scutellata, referring to the scutellum; a feminine adjective.

DIAGNOSIS: Antennal 1st flagellomere pale brown. Palpus brown except for pale yellow at third. Wing with a short hyaline stripe in cell cua 1; an elliptical hyaline spot in cell r 4+5, a semicircular hyaline apical stripe between R 2+3 and CuA 1, confluent with a digitiform hyaline stripe beyond dm-cu; a narrow pale brown stripe on r-m.

DESCRIPTION

Length: Body 2.1-2.8 mm (male), 2.2-2.8 mm (female); wing 3. 0-3.5 mm (male), 3. 0-3.3 mm (female).

Head yellow. Frons as long as wide and parallel-sided, with 2 brown stripes extending to ocellar triangle; ocellar triangle black; oc strong, as long as anterior or and anterior or shorter than posterior or. Face pale yellow, with a pair of shining brown lateral spots at ventral corner. Gena about 1/9 height of eye. Antennal scape brownish yellow, pedicel yellow and 1st flagellomere pale brown except yellow on base part of ventral margin, 1st flagellomere nearly 1.8 times longer than high; arista long plumose, black except for brownish base, with longest setula longer than height of 1st flagellomere. Proboscis yellow, with yellow and blackish setulae; palpus brown except for pale yellow at third, with black setulae.

Thorax blackish brown, slightly shining with sparse grayish white pruinosity. Mesonotum with broad yellow anterior margin; 0+3 dc, acr in 6 rows; prsc broken. 1 anepst, 1 kepst. Scutellum entirely yellow. Halter pale yellow except brown knob.

Legs yellow, except fore tibia slightly brownish yellow, mid and hind femora brown at tip, mid tibia brown on basal 1/2-2/3 and all tarsomeres 3-5 pale brown. Fore femur with 2 pv and 6 pd, ctenidium with 9-10 short setulae; fore tibia with 1 weak preapical ad and 1 apv. Mid femur with 4 a; mid tibia with 1 preapical ad and 2 strong apv. Hind femur with a row of weak av; hind tibia with 1 weak preapical ad and 1 short apv.

Wing (Plate B4) mostly brown, with a triangular hyaline stripe extending downward from Costa to M 1, a short hyaline stripe in cell cua 1; an elliptical hyaline spot in cell r 4+5, a semicircular hyaline apical stripe between R 2+3 and CuA 1, confluent with a digitiform hyaline stripe beyond dm-cu; a narrow pale brown stripe on r-m and a tinged brown triangular stripe over dm-cu, extending to the tip of CuA 1; apical part of subcostal cell brown; Costa with 2nd (between R 1 and R 2+3), 3rd (between R 2+3 and R 4+5) and 4th (between R 4+5 and M 1) sections in proportion of 1.9 mm: 0.6 mm: 0.5 mm; r-m beyond middle of distal cell; ultimate and penultimate sections of M 1 in proportion of 1.0 mm: 1.0 mm; ultimate section of CuA 1 about 1/5 of penultimate.

Abdomen blackish brown, slightly shining with sparse grayish white; protandrium and epandrium yellow. Male genitalia (Figs 16-20): protandrium semicircular; epandrium U-shaped in ventral view; surstylus short, curved downward; hypandrium U-shaped, gonopod transverse broad, undulating ventral margin with 1 apical seta in ventral view; aedeagus consisting of a small incision, a pair of triangular basal processes, an arch-like ventral sclerite with apical teeth and a pair of dorsal sclerites with acuate apical processes; aedeagal apodeme Y-shaped, longer than aedeagus.

REMARKS: The new species is very similar to Noonamyia sasakawai Papp from Thailand in the following characters: the wing has an incomplete hyaline stripe before the base of r-m, it lacks a round hyaline spot in cell dm, it has a semicircular hyaline marginal stripe between the tips of R 4+5 and CuA 1, the hind tibia has a short preapical ad, the scutellum is entirely yellow or brownish yellow, and the surstylus is acuate apically and curved backward. The new species differs from Noonamyia saskawai in details of the genitalia, particularly the epandrium having 3-4 long dorsal setae, and the gonopod having an undulating ventral margin and an apical seta. In Noonamyia sasakawai, the epandrium has 2 long dorsal setae and the gonopod is comma-like with a straight ventral margin and 1-2 subapical setae ventrally. The new species is also similar to Noonamyia euphlebia Sasakawa & Pong from Malaysia and Thailand in the following characters: legs with fore tibia slightly brownish yellow, mid and hind femora brown at tip and wing with an incomplete hyaline stripe before base of r-m. But it can be separated from the latter by the mid tibia brown on basal 1/2-2/3, the scutellum being yellow, the semicircular hyaline marginal stripe being present, and the epandrium with 3-4 pairs of dorsal setae. In Noonamyia euphlebia, the mid tibia is entirely brown, the scutellum is brownish black, the brown area in cell m 1 almost extends to the margin of wing but does not form a marginal stripe around to CuA 1, and the epandrium has 5-6 pairs of dorsal setae ( Sasakawa & Pong, 1990; Sasakawa, 1998).
