NEW LACEBUGS—DRAKE AND RUHOFF P71 
front margin opposite the collar to the hind margin of the paranotum 
and is fully as prominent as the median carina of the pronotum. 
Banahaona exalla, new species 
FicurE 16 
Description: Elongate, slender, with apical part of elytra blackish 
fuscous (both veins and cells); body beneath dark brown, the costal 
area testaceous with hyaline cells. Length 4.00 mm., width 1.10 mm. 
Head with five, short, appressed spines, antenniferous tubercles 
small; bucculae pale, triseriate, with ends contiguous in front. Labium 
brown with blackish tip, extending onto mesosternum; labial laminae 
not widely separated, very low on prosternum, considerably higher on 
mesosternum and mostly uniseriate, higher and mostly biseriate on 
metasternum. Antennae 1.52 mm. long; segment I brown, thicker 
and distinctly longer than II; segments II and III testaceous; segment 
IV fusiform, mostly dark fuscous; segmental measurements: I, 14; 
ae ATE65; TV, 26. 
Legs rather slender, sparsely furnished with very short setal hairs. 
Pronotum mostly concealed by completely refiexed paranota, only 
the median carina, posterior process, anterior part of collar, and small 
hood exposed; hood very small, not produced in front, triangular in 
outline; carinae without cells; lateral carinae visible on posterior 
process, entirely concealed under paranota on pronotum proper, con- 
verging to median carina on triangular process, then running along 
under paranota against median carina to beyond disc, thence slightly 
divergent to calli (paranotum removed to expose lateral carinae of 
pronotum). Paranota wide, resting against median carina, each 
paranotum with a long, median, longitudinal carina (as long as para- 
notum) and another much shorter longitudinal carina near humeral 
angle. ; 
Elytra much longer than abdomen, not wider than pronotum across 
humeral angles; costal area very long, narrow, uniseriate as far as apex 
of discoidal area, thence largely biseriate; subcostal area narrow, 
mostly uniseriate, biseriate in widest part opposite apex of discoidal 
area; discoidal area large, seven areolae deep in widest part just behind 
middle, two-thirds as long as elytra, acutely angulate at both ends, 
bounded by prominent boundary veins. Metathoracic wings dark 
fuscous. 
Typxrs: Holotype (male) and allotype (female), Mount Banahao, 
Luzon, Philippines, USNM 65125. 
Remarks: The holotype of B. exalla is illustrated in figure 16a. 
This is the only lacebug so far described that has two longitudinal 
carinae on each paranotum in addition to the three pronotal carinae.
