THE WASMANN JOURNAL OF BIOLOGY Vol. 9, No. 2 Sl"Ml\IEI{, 1951 A Taxonomic Revision of the Genus Maruina (Diptera: Psychodidae) LARRY W.

WIRTH, B'lt1·eatt of Entomology and Plant Qua1·antine, Ag1·ic·ztltttral R e search Administmtion, United States D e1Ja1·tn~ent of Agricultm·e The purpose of this paper is to clarify the taxonomy and nomenclature of that part of the Psychodidae involving the genus Maruinct Muller. The fact that 111a-ruina was represented in the North American fauua was not recognized until several years after l\Iuller 's original discovery of this unique genus in Brazil. After its presence in North America was realized, a number of species not congeneric with those described by Muller were placed in the genus. Nomenclatorial confusion has also resulted from the misassociation of stages of 111m·nina lanceolata ( P e1·icoma californiensis Kellogg) and P e·ricoma californica. Kincaid. This paper is based upon the study of correlated series of larvae, pupae, and adults of 111. lanceolata collected and reared by W. W. Wirth, cotypes of Sycom.c lcmceola.ta Kincaid, cotypes of P e·ricoma califo1·niensis Kellogg, cotypes of T·richomyia ttni punctata Haseman, cotypes of T1·ichomyia cirmtct Coquillett, holotype of Mantina nuda Dyar, holotype and paratypes of 111cwu.inct hirta Johannsen, and specimens of Maruina 1Jilosella Muller and M. lanceolata. A lectotype has been selected from the cotype series in the case of T. ttnipunctata. The authors wish to express their appreciation to Drs. A. E . Pritchard and R. J.J. Usinger for their aid and encouragement in this problem. Professor 'frevor Kincaid has most generously presented his entire psychodid collection to lVIr. Quate and this has been of great value in preparin"" the present paper. Dr. P etr Wygodzinsky most kindly made a special effort to coll ect all Received for publication Jan uary 9, 1951.

We wish to thank Dr. C. D. Michener, 1\Ir. Henry Dietrich, Professor G. F. F'erris, and Mr. C. P.

TYPE OF GENUS: Jlllm·uina pilosella 1\'liiller (apparently by designation of Enclerlein, 1937). l\Iiiller (1895) erected the genus li:Ian~ina on the basis of three species which he discovered in Brazil. The genus may be charac terized in the following manner: larvae onisciform with ei?·ht ventral suckers; pupae very much flattened elise-like, oval, caudal end rounded; adults with fifteen or sixteen-segmented antennae without ascoids, labium enlarged, flattened at apex, and wings narrow, lanceolate with radial sector three-branehed (only one long·itudinal vein between the forked veins), and the bases of the Rz ancll\C veins obliterated. The larvae and pupae are found PLATE I Figu re 1. Mantina. species A, dorsal view of pupa. 1a respiratory organ of pupa. Figure 2.

The adults are reclusive and seek shelter near t he stream in such places as deeply shaded marginal vegeta tion and bridges, which make convenient collecting places. Adults have never been taken in light traps ; in this respect they are unlike certain other psychodid species which ma~' be collected in large numbers by this method. At the present time t he genus is known f rom Brazil, Argentina, Puerto Rico, :i\fexico, Arizona, New Mexico, Colorado, California, and -w ashington. Future coll ecting of these t in~r cr·eatures will undoubtedly add considerably to the present meag·er knowledge of their distribution and reveal unrecognized species. The following are the .fh·e species which, in our opinion, belong to the genus jJ{arttina. Maruina hirta Johannsen, 1938. ( Plate I, figures 2, 2A ; pla,te II, figure 1.)
