A NEW SPECIES OF TRACHYSPHYRUS FROM THE 
ANDES OF ECUADOR 
(HYMENOPTERA, ICHNEUMONIDAE) 
By Charles C. Porter 
Biological Laboratories, Harvard University 
The author has just completed a revision of the South American 
species of the otherwise primarily Holarctic ichneumonid genus 
Trachysphyrus Haliday. This monograph is scheduled to be published 
before the end of 1967 by the American Entomological Institute. 
Although nearly 100 species are there treated, collections from much 
of South America are so inadequate that the discovery of many addi- 
tional forms is to be anticipated. Indeed, several more species have 
come to the author’s attention after the acceptance of his manuscript 
for publication. Some of these are represented by single specimens 
and their description seems best postponed until larger series are 
obtained. The species treated here, however is available in sufficient 
numbers to make possible a complete and reliable diagnosis and is 
also interesting as the second member of its genus to be described 
from the very poorly known Ecuadorian fauna.

Types: Holotype: (female) Ecuador (Cerro Tinajillas, 3200 m., 
March 18-21, 1965, L.E. Pena) (Townes). Paratypes: (i fe- 
male and 6 males). Ecuador (Cerro Tinajillas, 3200 m., March 
18-21, 1965, L.E. Pena; Targui, 1 2800 m., March 7-8, 1965, L.E. 
Pena) (Cambridge, Porter, Townes). 
Female: Color: antenna blackish with a white band, or some- 
times only dull brownish staining, above on flagellomeres 5-9; head, 
thorax, and propodeum black with white markings as follows: dull 
patch just above mandibular condyle ; sometimes tiny spot in middle 
of face below antennal sockets; orbital line: more or less interrupted 
on bottom of eye, on about lower 54 of hind-orbit, and sometimes 
irregularly near top of eye; transverse blotch on collar; narrow line, 
fragmented to practically complete, on Jatero-dorsal margin of pro- 
lr There is no such locality in atlases and gazetteers available to me. 
Probably this is a misspelling of Tarqui, a village in the same part of 
Ecuador as Cerro de Tinajillas.
