Pictures of distinctive traits
Morphologically close genera, and how to distinguish them:
  • Biastes - Ammobates & Pasites
Biastes species have a short and wide scapus, less than twice as long as wide. Females have a clear propodeal triangle and a bidentate mandible. Males have a labrum wider than long.
Ammobates and Pasites species have a normal scapus, longer. Females have a propodeal triangle faint and a unidentate mandible. Males have a labrum longer than wide.
  • Biastes - Ammobatoides & Schmiedeknechtia
Biastes species have a truncated marginal cell, basal part submarginal cell 1 is about as long as that of submarginal cell 2. Males have non-converging eyes.
Ammobatoides & Schmiedeknechtia species have an oval or pointed marginal cell, basal part of submarginal cell 1 is around twice as long as that of submarginal cell 2. Males have strongly converging eyes.
  • Biastes - Clavipanurgus, Flavipanurgus, Panurginus, Panurgus & Simpanurgus
Biastes species have a somewhat protruding clypeus and a long-tongue morphology (segments 1 and 2 of maxillary palpi are strongly elongated).
Clavipanurgus, Flavipanurgus, Panurginus, Panurgus & Simpanurgus species have a flat clypeus and a short-tongue morphology of mouthparts (short maxillary palpi).
General comments on Biastes species identification
Species identification criteria include the presence of spots of white hairs on the mesopleuron (B. emarginatus), the abdomen(B. truncatus) or neither (B. brevicornis).
Sorry, but the species identification tool is not yet available for Biastes.
