Trentepohlia (Mongoma) pennipes (O. S.) 



1887 Mongoma pennipes O. S. Berl. Ent. Zeit., vol. 31, part 2, p. 204. 



The immature stages of Trentepohlia pennipes have been described by 

 De Meijere (1911:50-51) as follows: Jacobson found the larvae at 

 Semerang, Java, in January, 1903, in decaying plant stems. The only 

 larva sent was 9 millimeters long and almost 1 millimeter in diameter, 

 of cylindrical form, only slightly narrowed behind and brownish in color. 

 The head capsule was entirely retracted. The entire body was thickly 

 beset with fine, short, appressed hairs; in addition to these, on the ventral 

 side of each of the six intermediate segments were transverse swellings 

 where the hairs were shorter and even more numerous. Surrounding 

 the anus were four long, cylindrical, anal gills, each constricted in three 

 or four places; if bent forward, the anterior pair would reach the middle 

 of the penultimate segment of the body, the posterior pair being somewhat 

 shorter. The last segment of the body was truncated, the lower angles 

 being somewhat produced and provided with a few somewhat longer 

 hairs; the spiracles, situated in the upper part of the spiracular field, 

 were relatively small and somewhat elongated. 



The pupa (Plate LXXVIII, 419) was about 9 millimeters long, elon- 

 gate, of a yellowish brown color, the abdomen for the most part brighter. 

 The thorax was almost smooth, with only a few short, brownish yellow 

 bristles. The abdomen, except on the anterior segments, was thickly set 

 with numerous tubercles. The apex of the abdomen had two short, thorn- 

 like projections, curved outwardly; beneath these were two shorter 

 tubercles, and four short tubercles formed a quadrangle on the dorsum 

 of the last segment. The pronotal breathing horns consisted of flat- 

 tened, leaflike lobes, the upper surface of which was scaly.

Trentepohlia (Paramongoma) hromeliadicola (Alex.) 



1912 Mongoma hromeliadicola Alex. Ent. News, vol. 23, p. 415-417. 



Trentepohlia hromeliadicola and T. leucoxena have a larval habitat 

 which has not been found elsewhere in the family. They live in the 

 water that gathers in the leaf axils of tropical bromeliaceous plants,
