Diagnosis.

Medium Oscinellinae with a pruinose frontal triangle and thorax. Wing with a dark apical spot. Male postabdomen small, not excessively higher than pre-epandrium.

Description.

Total length 2.4-2.9 mm. Overall colour black. Head. Frontal triangle black, pruinose, 0.5 times length of frons; ocellar tubercle black, microtomentose; frons yellow, heavily microtomentose; cephalic setae pale, eleven fronto-orbital setae weak-developed, interfrontal setulae on margin of frontal triangle, eight post-ocellar setulae small, posterior ocellar setae proclinate; gena white anteriorly, black posteriorly, microtomentose, 0.08 times eye height; eye hairy; face yellow; scape, pedicel brown, first flagellomere brown, yellow basoventrally, arista black, thin at base, pubescence sparse and short; palpus yellow in male, brown in female, proboscis and clypeus brown.

Scutum. Black, pollinose, acrostichal, and dorsocentral lines pruinosity with setae in 3 faint punctuate rows, notopleural bristle one anterior and two posterior relatively thick; outer postalar setae strong, black; dorsocentral setae strong, scutum 1.2 times longer than wide; scutellum brown, trapezoidal,1.35-1.50 times wider than long, microtomentose, rugose; apical scutellar setae strong, on small tubercles on upper margin of scutellum, lateral scutellar setae small, barely longer than other dorsal setae. Legs. Yellow, mid femur, hind femur and hind tibia black; femoral organ small patch on baso-anterior part of mid femur, tibial organ linear, pale, occupying middle quarter of hind tibia. Wing. Hyaline with distinct apical brown spot ( Fig. 4 ); veins brown; ratio of costal sectors C1: C2: C3: C4 - 1: 1.7: 1.1: 0.6; haltere white. Abdomen. Paler than thorax, sparsely microtomentose; Abdominal syntergites 1+2 slightly longer than other tergites. Male postabdomen ( Figs 31-34 ). Epandrium small, higher than long in lateral view, wider than high in posterior view, with many setae; surstylus 0.7 height of epandrium, straight, parallel-sided; cercus narrow with long ventral projection, cercus with sparse setae; Distiphallus weakly sclerotised.

Type material.

Holotype ♂: MEXICO: San Luis Potosi: Xilitla, 1800', 24.vii.1954, J.G. Chillcott (CNC); Paratypes: same data as holotype (5♂, 7♀, CNC); Guerrero, Taxco, 8mi NE, 5154', 8.viii.1954, J.G. Chillcott (1♀, CNC).

Etymology.

The species name is from the Latin maculatus (spotted), referring to the wing pattern.
