Smithsonian Contributions to Zoology, number 348, 27 pages, 53 figures, 1982.—A key, descriptions, distributions, and illustrations are provided for the 10 known species of the Neotropical genus Chloronia. Many of the first described species of Chloronia were placed in the Asian genus Neuromus, with which it shares the characteristic serrated abdominal appendages of the male. The most distinctive difference between Corydalus and Chloronia remains the terminal tooth of the ninth male gonostyle of Chloronia.
They lack the usual dark spots on the back of the head and have small 10th gonocoxites and quadratic ninth sternites, like the related genera. The three exclusively South American species appear (according to the present state of our knowledge) to form a different group of species, specialized by the elongation of the 10th gonostyli, but still retaining the approximately quadrangular ninth sternites. Chloronia gloriosoi still has the primitive elongated 10th tergite, but has modified the shape of the ninth gonostyli.
His collections at the Fortuna Dam site were made possible through the generous cooperation of the Panamanian Electricity Company (I.R.H.E.). One specimen (frontispiece) appears adult and bears the pronotal markings of the adult beneath the exoskeleton. In addition to these larvae, there are several collections available from Ecuador that clearly belong to two other species of the genus.
Fritz Plaumann, who has made great strides to bring the entomofauna of Santa Catarina state to the attention of specialists. INTRASPECIFIC VARIATION.-Besides the considerable variation in size, the dark spots in the cells of the forewing vary considerably in intensity. TEMPORARY DISTRIBUTION.—Adults were collected only between April 11 and June 15, despite congregating throughout most of the year in the same areas.
The presence of typical dark spots on the back of the head distinguishes it from the corripiens group. It would therefore appear to be the most unspecialized member of the spotted-head group and not closely related to any other known species, -. SPECIES RELATIONSHIPS.—This is a member of the hieroglyphic group, perhaps most closely related to C .
REMARKS ON TYPE.—The lack of a dark mark in the ocellar triangle may be an artifact due to separation of the tissues from the cuticle. Unfortunately, with the loss of genitalia and lack of additional material, we cannot determine the true situation. SPECIES RELATIONSHIPS.—Based on the originally published figures of the male genitalia and ignoring the triangular central mark, this species and C .

Manuscripts intended for serial publication are subject to content review at the original Smithsonian museums or offices and are submitted to the Smithsonian Institution Press on Form SI-36 with approval of the appropriate museum authority. Review of manuscripts and works of art by the Press for requirements relating to the format and style of the series, the completeness and clarity of the copy and the arrangement of all material, as described below, are, in the judgment of the Press, determines the acceptance or rejection of the manuscripts and art. .
The front matter (preceding the text) must contain the following: title page with only title and author and no other information, summary page with author/title/series/etc., according to the established format, table of contents with indents that reflect the main and structure of the paper. The first page of text should include the title and author at the top of the page and an unnumbered footnote at the bottom, consisting of the author's name and professional mailing address. Central heads of any level should be typed with capital letters at the beginning of the main words, with additional space above and below the head, but without any other preparation (such as capitalization or underlining).
Formal tables (numbered, with table heads, frames, stubs, rules) should be submitted as camera copy, but the author should contact the Serials Print Department for editorial and preparation assistance prior to final typing of this matter. Taxonomic keys in natural history papers should use the aligned pair format in the zoology and paleobiology series and the multilevel offset format in the botany series. If cross-referencing is necessary between the key and the text, do not include page references in the key, but instead number the excluded taxa with their corresponding heads in the text.
Synonymy in the zoology and paleobiology series should use the short form (taxon, author, year: page), with a full reference at the end of the paper under "Literature Cited". Footnotes, when few in number, whether annotative or bibliographical, should be printed at the bottom of the page of the text on which the reference is found. If bibliographic notes are required, use the short form (author/short title/page) with the full reference in the bibliography.
Use the double bracket system for volume/number/page citations. For alignment and arrangement of elements, follow the format of the series for which the manuscript is intended. Legends for illustrations should not be added to the art nor included in the text, but should be submitted at the end of the manuscript - with as many legends typed, double-spaced, on a page as is convenient. If several "figures" are treated as components of a single larger figure, they should be indicated in lowercase italics (underlined in the copy) on the figure, in the legend, and in text references: "Figure 9b.".
If illustrations are intended to be printed separately on coated paper after the text, they should be called plates and all parts should be lettered as in the figures: "Plate 9.b_.". Keys to symbols within an illustration should appear on the image and not in the legend.
