Spider Species in this genus
are found in silken cells in low vegetation in the open. They are not
colourful but sturdy and solid-looking.
This genus is squat, dull
brown coloured salticids with an appearance somewhat like Evarcha.
One well known species, H.
adansoni, is a great traveller which has turned up in many countries in
hothouses containing tropical plants.
The cephalothorax is thick,
the flat top extends on to the thorax with the rear slope of the thorax to
the margin very steep. The sides are vertical. In plan, the carapace is
U-shaped with the sides virtually parallel and the rear margin moderately
truncate. The abdomen is a broad oval, rounded at the front and very
slightly tapering to the rear. The legs are long and moderately spiny,
with legs I and II very slightly more robust than legs III and IV. The
dark brown eye area of the male H. adansoni is bordered by a light,
crescent-shaped area carrying white hairs. The rest of the carapace is
dark brown. The underlying colour of the abdomen is a mottled dark brown.
Around the shoulders there is a white crescent-shaped collar. Towards the
rear there is a vague, broad lightish area in the middle and several white
spots, two of which are prominent. The legs are uniform darkish brown. The
female is a lighter edition of the male and the white spots on the abdomen
are not evident.
Hasarius is widely spread
throughout the tropics, but many species placed in the genus are not
recognisable.
