17. Carabodes tridactylus nov. spec. 



ll-l. III. fig. 5, text-figs. 54, 55.) 



Although the present species is tridactyle I refer it to the genus Carabodes as 

 it undoubtly seems to be most closely related to C. labyi'intliicHs MiCH. [6, PI. 21, 

 fig. I]. 



Length 0,03 mm. Breadth 0,49 mm. 



Texture, rough. Colour, deep red-brown. The dorsal side of both cephalothora.K 

 and abdomen irregularly punctured and densely covered with small, hyalin, more or 

 less perpendicular, raised dots. 



Céphalothorax long, narrower than the abdomen and nearly in the same level, 

 anteriorly bluntly pointed. Lamelhe rather thick, and narrow, almost horizontal 

 plates with the same texture as the dorsal side; they run throughout their whole 

 length in a slight curve towards each other, extend forwards almost to the tip of 

 the céphalothorax, terminating in short cusps at the top of which the small, curved 

 lamellar hairs are inserted. 



Interlamellar hairs hairy, straight and blunt, 

 situated as far from the middle as from the pseu- 

 dostigmatic organs. Pseudostigmata large, lateral, 

 much raised, pointing outward. Pseudostigmatic 

 organs with slender peduncles curved outwards and 

 backwards, and pyriform bare heads (Text-fig. 55). 



First tectopedia ver\' large, shaped like the 

 lamella;, plainly seen from dorsal aspect. 



Legs. Coxae III rough with the same texture 

 as the dorsal side, flattened. Femora I and II with 

 slender peduncles; femora III and IV flattened with 

 high, longitudinal, ventral blades; genua I rather 

 long with slender basis; genua II — IV short; tarsi 

 and tibiœ I — IV (especially tibiae IV) rather long with 

 slender peduncles. All tibia: and genua I with long 

 tactile hairs. Claws tridactyle. slightly heterodactyle. 



Abdomen a little longer than it is broad; posterior margin rounded, antero-lateral 

 angles with a short, squared, flat projection; 4 rows of straight, blunt, hairy bristles 

 on dorsum of abdomen; 3 pairs of small hairs round the hind margin. 



Ventral side (Text-fig. 54). Texture the same as that of the dorsal side but 

 not so raised. Genital and anal apertures large, occupying nearly the whole median 

 part of the belly leaving between them a space only as long as '3 of the length of 



54-
