The tenebrionids belonging to the
tribe Cnodalonini Gistel, 1856
are small to very large (5–45 mm), of diverse shape and colour, apterous or winged. Antennae incrassate or weakly capitate,
with stellate sensoria on apical 5 or 6 antennomere. Tarsi with ventral surface
almost always flattened, bearing pads of yellowish, usually pilose setae; inner
margins of tibiae frequently pilose, especially near apices; tarsomeres 3 and 4 subequal (Aalbu
et al. 2002). As per the literature, only one species, Bradymerus
cucullatus Fairmaire,
1897 from the tribe Cnodalonini was reported from
Mumbai, Maharashtra State (Schawaller 2006). While
studying the recent collections from Western Ghats survey of Maharashtra State,
the two species identified as Promethis brevicornis (Westwood, 1842) and Gebienocamaria
girardi Masumoto, 1993 belonging to the same
tribe constitute two new records to Maharashtra. The number of species under Cnodalonini raised to three from Maharashtra. The specimens
are photographed using a Nikon D300s DSLR camera and deposited in the national
zoological collections of Western Regional Centre, Zoological Survey of India,
Pune.

Oken, 1843
Genus: Promethis
Pascoe, 1869
Species: brevicornis
(Westwood, 1842)
Diagnostic characters:
P. brevicornis can easily be differentiated

of hair fringe in the apical half of male protibia,
the separate strial punctures of the elytra and the
unmargined last ventrite as described by Fairmaire, 1896.

Masumoto, 1993
Diagnostic Characters: G. girardi can easily be differentiated by its pronotum
which is rectangular, 1.4 times as wide as long, irregularly punctuate, with
the corners projected and slightly reflexed; elytra a little more than 2.2
times as long as wide, 5.6 times the length and 1.7 times the width of pronotum
as described by Masumoto (1993).

width: 9.6 mm.
