Trentepohlia (Mongoma) pennipes (O. 8.) 
1887 Mongoma pennipes O..S. Berl. Ent. Zeit., vol. 31, part 2, p. 204. 
The immature stages of T’rentepohlia pennipes have been described by 
De Meijere (1911:50-51) as follows: Jacobson found the larvae at 
Semerang, Java, in January, 1906, 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 spirgculer field, 
were relatively small and somewhat clongated. 
The pupa (Plate LX XVIII, 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) bromeliadicola (Alex.) 
1912 Mongoma bromeliadicola Alex. Ent. News, vol. 23, p. 415-417. 
Trentepohlia bromeliadicola 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,
