The pattern on the top of the thorax, behind the eyes, for most Clubtails, other than Snaketails, falls into one of three categories
Does the front of the specimen's thorax have an upside down T shape marking with a parallel dash on either side ?
Is the front of the specimen's thorax comprised of 4 dashes that form a rough triangle ?
Does the front of the specimen's thorax have a U or W shaped marking ?
