Genus Heterosminthurus

  • Heterosminthurus bilineatus - moderately common (see below).
  • Heterosminthurus claviger - rare, a montane species found in pennine grasslands (similar in appearance to H. bilineatus, see below).
  • Heterosminthurus insignis - moderately common (a uniform yellow colour).
  • Heterosminthurus novemlineatus - very rare (yellow in colour with several (usually nine hence novemlineatus) longitudinal bands of dark pigment).

I am not currently aware of any Heterosminthurus records other than Heterosminthurus bilineatus from VC55.

Heterosminthurus bilineatus

In H. claviger the lateral stripes are connected posteriorly unlike H. bilineatus (here) which has separate lateral stripes:
Heterosminthurus bilineatus
H. claviger males (but not females) have peculiar paddle-shaped interocular setae.

The fourth antennal segment (ant4) is subdivided into about six subsegments:
