REVISED ALLOCATION OF A MEINERT SPECIES, 
WITH PROPOSAL OF A NEW SPECIES OF EURYTION 
(CHILOPODA : GEOPHILOMORPHA : 
CHILENOPHILIDAE)

When Meinert described Geophilus tcnebrosus as new in 1886 2 , 
he characterized it as having no ventral pores (“Pori ventrali nulli”), 
which almost surely accounts for Attem’s erroneous referral of it to 
Brachy geophilus in his celebrated ordinal monograph of 1929. 3 
Meinert’s original description is generally ambiguous; it provides no 
convincing clues that might have suggested to Atterns that the species 
is an Eurytion. 
The true generic identity of the Meinert form was readily ap- 
parent, when I examined the syntypical series in Copenhagen in i960. 
The specimens are plainly referable to Eurytion , a genus whose 
species are prevalent in southern South America, and southern Africa. 
Subsequently in a collection of Uruguayan specimens sent me for 
study of Dr. Pablo R. San Martin I discovered a specimen which is 
clearly referable to tenebrosum. This specimen, which agrees in all 
significant particulars with the syntypical material, is described here. 
The Uruguayan form was collected at Santa Clara de Olimar on 
November 17, 1958, by L. Lolessi. Because the origin of Meinert’s 
material is unclear from his original description, I present here a 
detailed citation: Argentina, State of Gran Chaco, Riacho del Oro, 
27' 03" S, 58' 33" w. 
Meinert’s syntypical series is comprised of five specimens: two 
females each with 57 leg pairs; two females each with 59 leg pairs; 
one male with 55 leg pairs. Of these a female with 57 leg pairs 
has been selected by me as the lectotype and appropriately labelled 
as such in the Copenhagan collection.. 
J This study was undertaken with the aid of a grant from the National 
Science Foundation. I should also like to express my gratitude for the loan 
of specimens and their hospitality to: Dr. Herbert W. Levi, Museum of 
Comparative Zoology, Harvard; Dr. S. L. Tuxen, Universitetets Zoologiske 
Museum, Copenhagen; Dr. Pablo R. San Martin, Museo Nacional de 
Historia Natural, Montevideo.
