FIGURES ./.3.4..5/1.54 
Plummerella DeLong, 1942b:200. Type-species: Plummerella alpina DeLong, by original 
designation and monotypy. 
Plumerella DeLong, loc. cit. (incorrect original spelling). 
Length 7.2-8.0 mm. 
Head very strongly produced and with anterior margin very narrowly 
rounded in dorsal view, median length of crown slightly greater than interoc- 
ular width, and more than nine-tenths transocular width, without a carina at 
transition from crown to face, ocelli located before a line between anterior eye 
angles, each ocellus slightly closer to median line than to adjacent anterior 
eye angle, crown convex to slightly flattened, with or without a transverse 
concavity across ocelli or before them; without a median fovea, surface finely — 
sculptured with lenticular impressions, lateral clypeal sutures extending onto 
crown and attaining ocelli; antennal ledges not protuberant, in lateral view 
with anterior margins vertical; median clypeal area with lenticular impres- 
sions, clypeus varying from rectilinear to slightly concave in profile, muscle 
impressions not distinct, transclypeal suture obsolete, clypellus not produced, 
its contour continuing profile of clypeus. 
Thorax with pronotal width slightly less than transocular width of head, 
lateral margins parallel, dorsopleural carinae complete, posterior margin con- 
cave, disk transversely rugose, not pubescent; scutellum transversely rugose or 
not behind transverse sulcus. Forewing with membrane involving only inner 
apical cell which may be partially or entirely membranous, veins not elevated, 
not very distinct, with three closed anteapical cells of which the bases are 
proximal to a transverse line through claval apex, with four apical cells of 
which the base of fourth is more proximal than base of third, without an an- 
teapical plexus of veins; forewings of female in rest position exceeding apex of 
ovipositor. Hindleg with femoral setal formula 2:1:1; length of first tarsomere 
less than combined length of two more distal tarsomeres and with two rows of 
small setae (the rows converging basally in some specimens) on plantar sur- 
face. 
Male genitalia: Pygofer well produced, apex broadly convex, with a: number 
of macrosetae located near posterior and posteroventral margins, pygofer 
processes absent. Plates slender, elongate, triangular, not extending pos- 
teriorly as far as pygofer apex, each with a single row of macrosetae. Style 
not extending posteriorly nearly as far as apex of connective, obliquely trun- 
cate apically, with preapical lobe occurring about midlength of shank. Con- 
nective elongate Y-shaped, the stem much longer than the arms and ex- 
tending posteriorly almost one-third its length beyond apices of styles. 
Aedeagus with shaft fairly short, almost straight, with or without processes. 
Paraphyses asymmetrical. 
Female abdominal sternum VII elongate, gradually tapered to apex which 
bears three small lobes. Genital chamber without sclerites. Ovipositor with 
second valvulae each broadened and toothed in slightly more than apical half,
