Pronotum gibbous, longer than wide, constricted before the basal margin, swollen near the apical margin, 0.74–0.80 times as wide as long (width measured excluding lateral spines), 0.83–0.86 times as long as humeral width; apical and basal margins straight.

Elytra elongate, weakly constricted behind humeral prominence, distinctly convex at middle, thence sloping towards the arcuately rounded apex; elytra 0.64–0.67 times as long as body, 2.48–2.68 times as long as pronotum, 2.14–2.22 times as long as humeral width; elytral disk post-basally with a pair of weakly developed callosities, followed by a pair of oblique depressions; area behind oblique depression on each side with a small, indistinct, shallow depressed area, adjacent to sub-lateral margin; each elytron with nearly 6 rows of punctures; row of punctures distinctly separated from each other, fades beyond the apical third; elytral disk with two feebly developed short carinae exterior to post-basal callosity and a sub-lateral carinae, originating just before middle, extends backwards and terminates at apical quarter.

Abdomen with last visible segment flat, broadly rounded at apex, 0.19–0.20 times as long as length of abdomen, 1.67–1.75 times as long as preceding segment.

Male genitalia ( Figs. 5–10 ). Tegmen about 0.80 mm long, sinuate in lateral view. Basal piece present, light brown, distally truncated, entire surface compactly packed with hexagonal cells. Ringed part converging, geniculated at widest portion, basal apodemes of ringed part united. Lateral lobes separated, widest at base, about 0.25 times as long as total length of tegmen; inner and outer margins parallel to each other; apex rounded; integument in ventral view, randomly distributed with setae bearing punctures, which are strongly concentrated at apex with a mixture of long and medium sized, light brown setae arising from them. Median lobe about 0.94 times as long as tegmen, arcuate in lateral view; basal struts originating from apical quarter; apex of ventral plate weakly projected; pre-apical area randomly distributed with a few punctures. Tergite VIII U-shaped; apex weakly crenulate, moderately fringed with medium sized light brown setae; lateral margins distally with a few similarly coloured setae. Sternite VIII rectangular, light brown in proximal half, covered with a few remotely distributed light brown sub-erect setae in distal half. Spiculum gastrale about 3.15 times as long as spiculum relictum, Y-shaped with arms curved outward; median apodeme of spiculum gastrale slightly bent towards right at its apex in ventral view.

Female (n= 9) ( Figs. 3–4 ). Body length 3.46–4.70 mm, humeral width 1.06–1.44 mm. Identical to male in general appearance. Head with lower eye lobes 1.50–1.67 times as long as genae. Antennae 0.97–1.09 times as long as body; ratio of length of antennomeres: 1.00: 0.29–0.33: 1.00: 1.00: 0.71–0.78: 0.64–0.67: 0.64–0.67: 0.56–0.57: 0.56– 0.57: 0.56–0.57: 0.64–0.67. Pronotum 0.83–0.88 times as wide as long, 0.77–0.80 times as long as humeral width. Elytra 0.66–0.68 times as long as body, 2.71–2.88 times as long as pronotal length, 2.17–2.23 times as long as humeral width. Last abdominal ventrite convex with pre-apical declivity, 0.24–0.28 times as long as abdomen, 2.25– 2.33 times as long as previous segment; apex broadly truncate.

Female genitalia ( Figs. 11–12 ). Ovipositor about 0.65 mm. Vagina about 1.44 times as long as ovipositor, 1.39 times as long as bursa copulatrix, uniformly cylindrical up to two-thirds of its length, moderately thickened at distal end. Bursa copulatrix clavate, about 1.04 times as long as ovipositor, about 0.72 times as long as vagina. Vaginal plates not discernible. Spermathecal duct distinctly long, tubular, twisted into C-shape at its basal quarter, enters bursa copulatrix at its apical third. Spermatheca with narrowly tubular pump, transversally convoluted at its base; receptacle capitate, distinctly constricted and curved at its middle; spermatheca arise separately along with spermathecal gland at the tip of spermathecal duct. Spermathecal gland elongated, narrow, tubular. Tignum shorter than abdomen. In the specimen examined, tignum measured about 1.25 mm while abdomen measured about 1.66 mm in length.

Differential diagnosis. The new species is similar to M. cleroides , but differs from it in the following characters: head and pronotum are red brown in the new species (dark brown to black in M. cleroides ); antennae are slightly longer than the body in the new species (antennae as long as the body in M. cleroides ); elytra almost unicolourous, entirely dark brown except for small basal portion and sutural margin (elytra bicoloured in M. cleroides ); elytron with 6 rows of punctures and a few fine carinae, with weakly developed post-basal callosity, without any white transverse pubescent bands (elytron with 7 rows of punctures and without carinae, with a welldeveloped denticulate post-basal callosity and a white transverse band at the middle and a large white pubescent patch at apical third in M. cleroides ). The new species is differentiated from the previously reported Indian species ( M. relucens and M. rugosula ) based on the key.

Etymology. The name ferruginea refers to the general body coloration of the new species; adjective.

Habit. The new species is nocturnal. The specimens were collected at light of mercury vapour lamp, LED and actinic blue ‘UV’ bulbs.

Seasonal occurrences. The specimens in the present study were collected during January, February, March, April, May, June, July and November, indicating adult activity throughout the year.

Distribution. India: Kerala: Vellayani (Trivandrum Dist.), Tirurangadi (Malappuram Dist.), Pampadumpara (Idukki dist.). Karnataka: Castle Rock (Uttara Kannada Dist.). The new species is distributed in coastal and hilly areas. This is the first record of the genus Miccolamia from southern India.
