Taenogera luteola sp. nov.

Holotype female, AUSTRALIA: QUEENSLAND: Malanda, 25.viii.1966, D. Smith (MEI 27819) (Type #: T.144007) ( QMBA). Condition: good.

Diagnosis. Wing with distinct infuscation along anterior margin; pleuron with only sparse pubescence; scutum largely glabrous with gold velutum pubescence similar to T. longa and T. notatithorax ; abdomen patterned with yellow and brown banding.

Description. Female: Body length: 13.5 mm.

Head. Frons glossy black-brown, slightly rugose, much wider than ocellar tubercle at narrowest point, gold, elongate setae sparsely distributed laterally on frons; face and area around antennal bases overlain with dense, gold velutinous pubescence; ocellar tubercle raised, glabrous except for sparse, elongate setae; occiput convex, overlain with broad band of dense, velutinous, silver pubescence along postocular ridge extending ventrally onto gena, multiple rows of orange postocular setae; gena with more slender, dark setae; mouthparts orange-brown, covered with numerous dark setae; antenna slightly shorter than head, orange-grey pubescent; scape and pedicel with orange setae; flagellum tapered, longer than combined length of scape and pedicel.

Thorax. Scutum glossy black with patches of gold, velutinous pubescence similar to T. longa and T. notatithorax (see Winterton et al. 1999b, fig. 35) but differing to these species by the absence of small, medial dorsocentral patches and having a single quadrangular shaped patch between dorsocentral setae posteriorly on scutum; scutellum yellow-brown with faint gold pubescence along anterior margin; scutum and scutellum with sparse, slender covering of pale setae; pleuron and coxae dark brown, faintly overlain with silver-grey pubescence, denser gold velutinous pubescence on postpronotum, proepisternum and katatergite, admixed with pale setae on postpronotum, proepisternum, katatergite dorsal portion of anepisternum and coxae; legs yellow, femora dark brown except for apices, covered with short, pale setae; tibia with orange macrosetae, fore tibia and tarsi brown; wing mostly hyaline, covered with minute orange microtrichia on most of wing area except intervenal area, basal medial cell and basal portions of discal and anal cells, distinct smoky infuscation of anterior margin of wing and area between cubital and posterior cubital veins; haltere yellow; scutal macrosetae orange, scutal chaetotaxy (pairs): np, 4; sa, 2; pa, 1; dc, 2; sc, 2 (outer setae smaller).

Abdomen. Elongate, patterned with yellow, brown and black, covered with sparse, pale setae; tergite 1 brown anteriorly, yellow along posterior margin; tergites 2–3 yellow with brown band anteriorly (broader laterally) and two triangular markings along posterior margin, two triangular shaped, gold, velutum patches midway along tergite; sternites 2–3

yellow; segments 4–6 mostly brown with yellow posterior margin (margin broader on segment 6); segments 7–8 and terminalia yellow.

Female Genitalia. Not dissected.

Male. Unknown.

Etymology. The specific epithet is derived from the Latin: luteolus, dim., yellowish; referring to the yellow body colour.

Comments. Taenogera luteola sp. nov. is known only from a single female specimen collected in Northern Queensland. It is closely related to T. notatithorax and T. longa based on the distinctive body colouration and vestiture.
