For me, the shortish tarsi and head shape suggest Billaea, maybe triangulifera from the abdominal pattern. Regards, Steve |

Hi Steve, thank you very much! You are right - was to early for me or I need new glasses! Dinera females's tarsi are not so extreme as the male's but it's Billaea triangulifera! Greetings, Eric |

Thanks Eric and Steve, I tried to find a picture where the comb on the tibia 3 could be seen. Is it what we see on this one ? Christine |

Hi Christine, this seems to be the comb on tibia 3 as mentioned in the key (the female's comb is more irregular with bristles between). Greetings, Eric |

The abdominal,pattern in last picture clearly shows triangulifera. Abdominal pattern is best seen obliquely from behind. As mentioned by Eric, the comb on hind tibia is hardy regular in female triiangulifera. Theo |
