Lii'laps (La^Iaps) muricola n. sp. 



(PL 2. figs. 17 A 22. n. 3, tigs. 1, 4, 12, 13 & 31.) 



Male. Average lengtli l,oi mm. Greatest Avidth 0,69. 



Female. (witli 1 large egg). Average length 1,4 mm, Greatest width 0,98 mm. 



The male. 



The colour is pale yellow. The general shape and the dorsal shield like 

 that of Lmlaps agilis C. L. Koch [compare Berlese, Mesostigmata, tab. 50]. 



Texture scaly; the weak parts of the cviticle finely wrinkled. 



Ventral side. (PL 3, fig. 4.) 



Tritosterniim of the usual shape. Sternal, metasternal, endopodal, ventral 

 and anal shields fused to one shield which exhibits a scal}^ texture. Genital aper- 

 ture broad oval, projecting slightly beyond the anterior edge of the sternal shield. 

 No demarcation visible between the sternal and the endopodal shields. 



There are 5 pairs of long, sharply pointed bristles on the sterno-metasternal 

 portion, placed as foUows: one joalr at the front edge half way between the genital 

 aperture and the antero-lateral corners; one marginal pair on a line with the middle 

 of coxse II ; one pair in the corner between coxse II and III, one pair in the corner 

 between coxse III and IV and one pair on a line with the posterior margin of 

 coxse IV. 



Ventri-anal portion large and triangulär; the antero-lateral corners are rounded 

 and extend beyond coxa? IV; the lateral sides are wavy and slightly excavated on a 

 level with the anal aperture. 



On the ventral portion there are no small hairs, only 5 pairs of bristles arranged 

 as fig. 4. shows; round the anal aperture the usual 3 hairs, of which the terminal 

 one is long and straight. 



No inguinal shields. 



On the soft portion between the ventri-anal shield and the margin of the body 

 there are about 25 pairs of somewhat smaller bristles. 



Stigmata on a line between coxse III and IV, the peritremata extend for- 

 ward only to the middle of coxpe II but they are continued by chitinous ridges which 

 rnn beyond the coxse I and coalesce with the anterior margin of the dorsal shield 

 above the rostrum. The peritrematic shields are, allthough weak and narrow, 

 distinctly discernible on the external side of the peritremata. 



The epistoma is broad and rather short, nearly semicircular, with the edge 

 divided into fine lobes or fringes, which increase in length towards the top. The 

 mandibles (PI. 3, fig. 13.). Near the base of the chela, on the dorsal side, there
