clypeus in anterior view of head. Pretarsal claws as in Troctopso- 
copsis. Terminal segment of maxillary palpus elongate, rounded 
apically (fig. 49). M-cu crossvein present in forewing. Subgenital 
plate with posterior margin tapering, bearing 4 stout setae in middle; 
with T-shaped sclerite. Phallosome a simple Y-shaped structure. 
Type species. — Plaumannia separata Roesler. 
T'roctopsocus separates (Roesler) 
Plaumannia separata Roesler, 1940, Zool. Anz. 129:236-237, figs. 
15-20. 
(Note: Specimens from Trinidad, W.I., described below, are 
assumed to be this species. They agree essentially with Roesler’s 
figures of wing markings, and they agree as closely as is likely with 
Roesler’s figures of lacinial tip and ovipositor valvulae. They average 
generally slightly smaller than Roesler’s Brazilian specimens). 
Diagnosis. — Wing markings essentially as illustrated by Roesler 
(1940: 236, fig. 15). Spermathecal sac with short, slender basal 
region and a constriction between this region and wide distal region. 
Ovipositor valvulae : basal arms of first and second valvulae much 
longer than in T. similis , n. sp. ; secondary lobe of third valvula only 
slightly spinose. 
Male: Measurements (Table I). 
Morphology. — Hypandrium with posterior margin gently curved. 
Phallosome typical of the genus (as in fig. 63). Posterior margin 
of clunium bordering epiproct slightly thickened and with slightly 
scalloped edge, interrupted by smooth edge in middle. Epiproct with 
postero-mesal field of tiny papillae. Paraproctal sensorium with 7 
trichobothria and 2 setae without basal rosettes. 
Color (in alcohol). — Differing from Roesler’s description only 
as follows: stripe from eye to mandibular base reddish brown; in 
addition to central spot from ocelli to clypeus, each lateral edge of 
frons with a (pale brown) spot; vertex with longitudinal brown 
stripe immediately to each side of midline, but pale on midline. 
Reddish brown spots on abdomen distributed as a latero-ventral 
series on each side (one spot per series per segment) including seg- 
ments 1 to 4; ventral transverse bands connecting the spots in 
segments 1 and 2 ; small spot surrounding each spiracle in segments 
bearing spiracles. 
Female: Measurements (Table I). 
Morphology. — Lacinial tip (fig. 68) with lateral cusp bearing 
two appressed denticles. Subgenital plate with apex less tapering than 
in T. similis and T. bicolor. Ovipositor valvulae (fig. 59) as de-
