This species is represented by a single individual from 

 Mabuiag. It is allied to Mayr's L, minnta, but differs in its 

 black colour and yellow markings. The last antennal joint of 

 the specimen is, unfortunately, missing.

Body elongated, oval ; the entire insect clothed with long, 

 fine hairs. Head broadly triangular, rounded in front. Eyes 

 rather small, facets large. Ocelli absent. Antennae as long as 

 body, four- jointed, first and second joints sub-equal, third and 

 fourth shorter and sub- equal ; a minute jointlet between the 

 second and third, and third and fourth joints. Eostrum four- 

 jointed, first joint long, broad ; second joint the shortest, ring- 

 like ; third joint long, tapering ; fourth joint narrow and pointed. 

 Thorax, with its three divisions fused together, extending back- 

 ward above, below, and at sides of abdomen, which it largely 

 conceals ; pro-, meso-, and meta-nota forming an oval, moderately 

 convex, dorsal plate ; pro- and meso-sterna forming a large and 

 flat ventral plate ; the abdomen, as viewed from above, is embraced 

 laterally by what appear to be reflexed, backward prolongations 

 of the thoracic epimera; only hinder edge of meta-sternum visible. 

 Elytra and wings absent. Front acetabulse near the central line, 

 middle and hind acetabulse situated laterally, the latter far back. 

 Front legs very stout, moderately long ; coxae much thickened ; tro- 

 chanters thickened and bent ; femoravery greatly thickened, toothed; 

 tibise thickened, toothed, bent at right angles from their insertion ; 

 tarsi three- jointed, proximal joint very short, distal joint thickened, 

 with claws inserted beneath, midway in its length. Middle and 

 hind legs of nearly equal length, longer than front pair ; coxse of 

 both pairs very long and broad, those of hind pair reaching 

 backward nearly as far as the extremity of the abdomen ; 

 trochanters of both pairs thickened and bent ; femora of middle 

 pair slender, of hind pair spindle-shaped ; tibise and tarsi slender 

 in both pairs, the latter with claws inserted just beneath their 

 extremities. All tarsi with three claws, two stout and one fine.
