Macropsella recta sp. nov.

( Figs. 1–6 , 19–25 )

Description: Length. ♂ 3.0– 3.2 mm, ♀ 3.4–3.5 mm.

Body light brown. Head and pronotum with punctuation darker than surrounding area. Mesonotal triangles and scutellum brown with darker speckles and dark brown lateral corners ( Fig. 1 ). Forewing translucent brown, veins usually marked with white spots but otherwise concolorous with membrane ( Fig. 2 ). Face yellowish brown, striations of same color. Eyes red brown ( Fig. 3 ).

Body wedge shaped. Head, face, pronotum and scutellum with dense striations and punctations, Median longitudinal carina on face, pronotum and scutelllum distinct. Head width equal or subequal to pronotum. Crown short. Pronotum moderately to distinctly declivous anteriorly, striae oblique. Scutellum sometimes pitted, with median carina along entire length ( Fig. 1 ). Forewing with 3 preapical cells. Hind tibial chaetotaxy PD 11, AD 8, AV 5 ( Fig. 2 ). Face narrower between eyes than its median length; with lower part of face inflated; distance between ocelli 3 times distance from ocellus to adjacent eye; coronal pits poorly developed, slightly further apart than ocelli; anteclypeus small ( Fig. 3 ).

Male genitalia. Male pygofer short with truncate apex, armed with posterior spine directed laterad and small lobe directed caudad, pygofer bearing distinct group of setae on either side of posterior half. Subgenital plates parallel-sided from base to evenly rounded apex, with numerous irregularly arranged fine setae, dorsal preapical setae longest ( Figs. 19, 20 ). Aedeagus tubular, with preatrium short, shaft compressed, in lateral view nearly straight in basal 2/3 with anterodorsal prominence preapically, apex abruptly narrowed and curved anterodorsad with rounded apex; in posterior view with atrium pear-shaped, shaft slender, parallel-sided, gonopore apical. Dorsal connective almost reaching dorsal margin of pygofer, situate in both lateral and posterior views, flattened and tapered dorsoapically ( Figs. 21, 22 ). Style slender, angled on basal 1/3, gradually tapering distally, with slightly reflexed tips ( Fig. 23 ). Connective small, posterior margin truncate, median anterior lobe well developed between dorsally bent anterolateral arms ( Figs. 24, 25 ).

Female. Body coloration and appearance similar to male, but the former has paler colored face ( Figs. 4–6 ).

Material examined. Holotype: ♂, Australia: Queensland, 6 Victor Place, Kuranda , Home of Max Moulds and Margaret Humphrey , 16°48.923’S, 145°38.550’E; 395m, 7 Feb 2011, Coll. K. Hilletal, D. Marshall, C. Owen, M. Moulds and M. Humphrey, MV light (QM) ; Paratypes: 3♂♂ 5♀♀, same data as holotype ( INHS).

Distribution. Australia.

Remarks. The new species is similar to M. novabritanniae (Evans) but differs in the shape of the aedeagus and dorsal connective.

Etymology. The new species name is derived from the latin word “ rectus ”, referring to the straight caudal margin of the male pygofer.
