The parenthesis that ends the url of this comment seems not to be considered as part of the link.
The same bug bug was reported on Meta StackOverflow and apparently corrected.

This is intentional as far as automatically linked URLs go. See this answer of mine for the reason.
If, on the other hand, you explicitly say "the link starts here and ends here" by using the link syntax
[see wikipedia](http://en.wikipedia.org/wiki/Kingdom_(biology))
it will work, since we allow one level of opened/closed parenthesis, specifically for cases like Wikipedia links.
See URL detecting error with address like "http://en.wikipedia.org/wiki/Octet_(computing)" on Meta Stack Overflow for details; long story short: After the next build of the site, this will work as you had expected.
This is easily addressed. A link like this:
http://en.wikipedia.org/wiki/Kingdom_(biology)
and be rewritten with its nonalphanumerics translated into hex using the %XX
notation. The ASCII hex set is:
00 nul 01 soh 02 stx 03 etx 04 eot 05 enq 06 ack 07 bel
08 bs 09 ht 0a nl 0b vt 0c np 0d cr 0e so 0f si
10 dle 11 dc1 12 dc2 13 dc3 14 dc4 15 nak 16 syn 17 etb
18 can 19 em 1a sub 1b esc 1c fs 1d gs 1e rs 1f us
20 sp 21 ! 22 " 23 # 24 $ 25 % 26 & 27 '
28 ( 29 ) 2a * 2b + 2c , 2d - 2e . 2f /
30 0 31 1 32 2 33 3 34 4 35 5 36 6 37 7
38 8 39 9 3a : 3b ; 3c < 3d = 3e > 3f ?
40 @ 41 A 42 B 43 C 44 D 45 E 46 F 47 G
48 H 49 I 4a J 4b K 4c L 4d M 4e N 4f O
50 P 51 Q 52 R 53 S 54 T 55 U 56 V 57 W
58 X 59 Y 5a Z 5b [ 5c \ 5d ] 5e ^ 5f _
60 ` 61 a 62 b 63 c 64 d 65 e 66 f 67 g
68 h 69 i 6a j 6b k 6c l 6d m 6e n 6f o
70 p 71 q 72 r 73 s 74 t 75 u 76 v 77 w
78 x 79 y 7a z 7b { 7c | 7d } 7e ~ 7f del
And so subbing in the hex for the parens the version of that URL that works is:
http://en.wikipedia.org/wiki/Kingdom_%28biology%29
This is easily shown to work by comparing this which works with this which fails.

Hm, actually, those both work! In fact, I can’t manage to get a failure mode to crop up. Do you have an example of something that doesn’t work right?
Perhaps balanced parens work but imbalanced ones do not? Unsure; I have no failure test case. But I’ll bet you anything that subbing in the hex for offending characters will cure whatever problem ails you.
Maybe it’s only in comments where the putative pesky paren problem arises? This comment uses the URL above, properly escaped, without a hitch.
So I think this is easily worked around.
