dense series of slightly oblique cross veins; MA with two branches, 
MP richly branched, forking about eight times; CuA with three 
branches; C11P forking six times; anal area long and narrow, with 
six to eight forking branches; cross veins numerous, often curved, 
irregular and sometimes anastomosed. Hind wing: length 62 mm, 
width 24 mm, broadest at the end of the first third, with moderately 
rounded anal area. 
Body structures: Head with reniform eyes, extending nearly to 
the clypeus; length of clypeus 3 mm, width 1.3 mm, rectangular in 
form, rounded anteriorly; transverse ridges oblique in the posterior 
region of the clypeus. Prothoracic lobes with about eleven veins, 
sometimes forked, and with numerous cross veins. Prothorax as long 
as the mesothorax, metathorax 1.5 times longer than mesothorax. 
Abdomen slenderer than metathorax, with segments 1-2 only a little 
shorter than the longest one, segment 3. 
T. grehanti is unusual in having a very small head, the reniform 
eyes and the very large metathorax. 
Genus Spiloptilus Handlirsch 
Spiloptilus Handlirsch, 1906: 100. 
Type species: Graphiptilus ramondi Brongniart (OD). 
Although Handlirsch was undoubtedly correct in establishing a 
separate genus for ramondi , he was incorrect in placing it in the 
family Graphiptilidae ; this error was made because he was under the 
impression that MA in ramondi was unbranched. The generic char- 
acters are revised here on the basis of my examination of the type 
specimen of ramondi , in which I have been able to determine more 
details about the structure of the Rs and anal area. 
Wing: membrane dark; cuticular thickening unknown; support- 
ing cross veins not present; anterior margin, Sc and Ri unknown; Rs 
diverging from Ri just beyond the first third of the wing, with a few 
branches, which may be forked; MA well developed, forking several 
times; MP with several branches; both CuA and CuP pectinate; anal 
area relatively small; cross veins numerous, simple, regular in form 
and equally distributed. 
Spiloptilus differs from all other genera in the more distal origin 
of Rs, but detailed comparison with other genera is not possible be- 
cause of the poor preservation of the type, the only known species of 
Spiloptilus.
