141); bulb dark brown, anterior haematodocha clearly separated; embolus somewhat triangular, very large and broad, slightly curved (Fig.
On two occasions where the complete sequences were observed, the male made 17 and 29 flubs before the palp engaged with the epigynum and the haematodocha was finally inflated.
Pedipalps dark, tibial apophysis curved (Figs 203, 204), bulb dark brown, anterior haematodocha clearly separated, embolus short (Fig.
Bulb oval, distal haematodocha separated, embolus longer than in congeners, linguiform (Fig.
Male palpal structures: basal haematodocha (BH), conductor (CON), cymbium (CYM), distal haematodocha (DH), embolus (EMB), lunar plate of the subtegulum (LPS), median apophysis (MA), palea region (PR), tegulum (TEG), terminal apophysis (TA).
18): palea swollen; embolus and ejaculatory duct extended, join together immediately before terminal apophysis which projects over and across them; lunar plate of subtegulum below the tegulum and above the basal haematodocha; distal haematodocha partly visible beneath embolus and terminal apophysis relative to the position of the median apophysis.
Basal haematodocha: The membranous basal haematodocha connects the alveolus to the subtegulum (Figs.
According to our observations, theridiids generally lack a petiole, although a small, indistinct, and lightly sclerotized region within the basal haematodocha in some taxa may be homologous to the petiole.
Subtegulum: The subtegulum is the ringlike sclerite that forms the base of the bulb, and connects to the alveolus via the basal haematodocha and to the tegulum via the middle haematodocha.
In Micropoltys the sperm duct appears to pass from the radix, through the base of the distal haematodocha and straight into the embolus.
