chamberlin: myriopoda of the Australian region. 155 



419. lophodesmus lamprus, sp. iiov. 



Ti^PE.— M. C. Z. 4,597. Paratypes.— :M. C. Z. 4,598, 4,599. 

 Fijis: Somo Somo, Lasema (W. M. Mann). 



The metazonites above are dark brown with the keels fulvous excei)ting 

 along the margins where the dark color is maintained, or sometimes dark 

 throughout. Prozonites and head fulvous, the latter punctate with brown 

 above; legs, antennae, and porigerous cones paler, whitish. 



The head conspicuously tubercular above the level of the antennae, the 

 outer row of tubercles on each side curving ectad above. Hairs of face 

 numerous, exceedingly short. 



First tergite of usual form, presenting below a marginal lobate rim in which 

 the emarginations are deep and the lobes well rounded; front face of the 

 median portion steep, almost vertical; the height obviously exceeding the 

 length; surface densely tubercular and with two transverse series of much 

 more prominent tubercles which are widely separated, four tubercles in the 

 anterior of these series and six in the posterior. Other tergites with three 

 principal transverse rows of tubercles but an irregular and incomplete fourth 

 row often traceable. Dorsal combs high, the three tubercles of each fused 

 at base; the tubercles of the prominent lateral series also high and conspicu- 

 ous. The submedian combs of three tergites preceding the ultimate pro- 

 gressively higher, those of the nineteenth basaUj' fused together and projecting 

 caudad widely beyond the anal tergite which is thus completely concealed 

 from above. The keels of the second tergite lateralh- trilobed with the 

 median lobe smallest ; the other non-porigerous keels laterally bilobed except- 

 ing the seventeenth and eighteenth, which are trilobed. The porigerous keels 

 are as if laterally trilobed with the caudal lobe subdivided and the pore-cone 

 projecting freely between the two resulting smaller lobes. The marginal 

 lobation and the position of the pore-cone readily chstinguish this form from 

 L. piisillus, the genotj^e, and the Javan lobidatus. 



In the male gonopods in lateral view projecting below the large coxa, in a 

 place bent forward and then slightly up at tip, somewhat avicular in form. 



Length, to about 6.5 mm.; width, 1.1 mm.

Color above dark brown, the keels paler, more fulvous. Sternites with 

 legs and antennae fulvous; head the .same excepting frontal, region which is 

 finely dotted with bromi. 



Body not quite five times longer than wide. Dorsum high, the keels nar- 

 row, strongly depressed.
