The scientific publications of the United States National Museum include two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In this series, original articles and monographs are published which deal with the collections and work of the Museum and which outline newly acquired facts in the fields of anthropology, biology, geology, history and technology. It was collected in volumes, octavo in size, with the date of publication of each paper noted in the table of contents of the volume.
In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (sometimes in several parts) and volumes containing collected works on related subjects. Since 1902 papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium. This paper remains today the outstanding systematic work on the Diplopoda of the area included in this checklist.
Today this scattered literature contains descriptions and records of over 750 more or less known species, but this number is only a small part of the undiscovered ones that inhabit this great warm-temperate area. A major reason for the backward state of our knowledge of the centipedes of this region, or most of its parts, is probably that none of the eight countries has ever produced a recognized diplopod taxonomist or any outstanding collectors, except Dr.

Although reported from Darien Prov., Panama, it is doubtful whether the identification was correct or whether the species can be re-identified (see Loomis 1964a, p. 34). PARATYPE PLACES: Same, and west of Finca Palo Santo, near Nueva California, Chiriqui Prov., Panama.

Inner gonopods with outer nodes in a nearly continuous straight line, with heavy basal elements ALLOPOCOC KIIDAE. Anterior gonopods with mesal margins long and in contact very long; segment 2 usually with a spirobolus-like production below. Anterior gonopods with mesal margins short or, if elongate, generally well separated, rarely in contact for a short distance; Segment 2 is very rarely produced below the lateral angle of segment 1.
First segment with anterior and posterior margins on each side converging downwards to an acute angle ATOPETHOLID AE. First segment with anterior and posterior margins on each side not strongly converging downward; lateral margin broadly rounded.

OTHER LOCALS: Santo Domingo de San Mateo, Costa Rica (Chamberlin 1922 for G. Pacificus); different localities in nine departments of El Salvador (Kraus 1954b). Based on the structure of the gonopods, it seems necessary to return this species to its original name.
