Valid name. Rivellia maculipennis ( Bigot, 1886) , comb. n. ( Platystomatidae )

Cephalia ? maculipennis Bigot, 1886: 385 .

Cephalia maculipennis: Steyskal, 1965: 643 (as “unrecognized”); Poole & Gentili, 1996: 203.

Rivellia brevifasciata Johnson, 1900: 326 ; Hendel, 1914 a: 177; Cresson, 1924: 229; Namba, 1956: 54; Steyskal, 1965b: 643, syn. n.

O r i g i n a l d e s c r i p t i o n o f Cephalia maculipennis : “Antennis basi fulvis (segmentum tertium abest); capite palpis que nigris; thorace scutelloque nigro nitido, tergo aenescente; abdomine nigro nitido metallescente; halteribus nigris; pedibus fulvis; alis hyalinis, venis flavis, transversis, lineisque dudibus minimis, transversalibus et basi, extrinsecus, macula apicali, costa denique, anguste, fuscanis.

Les deux premiers segments des antennes fauves (troisième manque); tête et palpes noires, orbites finement bordés de grisâtre; thorax d’un noir luisant ainsi que l’écusson, tergum d’une nuance bronzée obscure; balanciers noirs; abdomen d’un noir luisant avec des reflets métalliques obscurs; pieds fauves; ailes hyalines, nervure costale, les deux transversaîes et doux petites lignes transverses situées extérieurement vers la base, enfin, une macule de médiocre dimension, s’anastomosant en arrière avec la nuance qui borde la nervure costale, noirâtres.

Amér. septentr. (Rockey-Mount.). — 1 spécim. — Long. 4 millim.”

[English translation: (from Latin) Base of antennae yellowish brown (third segment is absent); head and palps black; thorax and scutellum glossy black, the back bronzed; abdomen black and shiny metallic; halteres black; legs yellowish brown; wings hyaline, veins yellow, extended, with few transverse veins, the transverse ones and their bases extrinsic; with apical blotch; costa narrow all the way, darkened.

(From French) The first two segments of the antennae fawn (third missing); head and palps black, orbits finely edged grayish; thorax shiny black as well as the scutellum, dorsum with dark bronze sheen; halteres black; abdomen shiny black with dark metallic sheen; legs fawn; wings hyaline, costal vein, the two transverse veins and the soft small transverse veins located externally towards the base, finally, a blotch of poor size, joining backwards with the shade bordering the costal vein, blackish.

North America (Rockey-Mount.). — 1 specim. — Length 4 mm.]

O r i g i n a l d e s c r i p t i o n o f Rivellia brevifasciata : “Ơ ♀. Lower half of the face shining black, upper half opaque, front brown, opaque, vertex with three shining black spots, the central one surrounding the ocelli, frontal and facial orbits silvery; occiput black, antennae reddish, tip of third antennal segment dark brown. Thorax and abdomen with uniform dark green [sheen]. Legs entirely light yellow. The four crossbands on the wings are obsolete or greatly abbreviated, the first and second costal cells are hyaline; the first band consists only of a spot in the marginal cell: the second and third bands do not extend beyond the fourth longitudinal vein; the fourth, or apical band, about the same as in R. flavimana , but not connected with the third along the costal margin. Length 4 mm.

This species is nearest related to R. flavimana Loew , from which it is at once separated by the obsolete bands and hyaline costal cells.

Atco, June 18, 1893. I have also two specimens from Dr. Garry deN. Hough, collected by Mr. G. R. Pilate at Tifton, Ga., June 6th.”

Remarks: The holotype of Cephalia maculipennis Bigot is clearly conspecific with the other specimens described by Johnson and redescribed by Namba. We therefore consider Cephalia maculipennis Bigot, 1886 and Rivellia brevifasciata Johnson, 1900 to be synonyms.
