- Sesieutes minuatus
Natural history Males of this new species clearly mimic ants. Their opisthosoma is entirely encapsulated with an elongate-ovoid dorsal scutum, which is clothed with white hairs and underlying dark greyish dorsal pattern. Together with a stalk-like pedicel, they give an appearance of a segmented abdomen of the ants. The presence of rows of short, straight bristles on dorsal and ventral surface of leg segments also give an impression of the setae in ants.
Diagnosis Males of S. minuatus sp. nov. are recognized by the presence of a rectangular projection on the apex of the proximal RTA (Figures 3 L, 5 A, C), in combination with the medially situated conductor. Males are distinguished from their congeners by the minute distal RTA (Figures 3 L, 5 C). Females can be distinguished from those of the closely related S. emancipatus sp. nov. by the longer grooves on the epigynal region (Figures 5 D cf. 10 E), the more elongated and strongly arched proximal ducts in dorsal view (Figure 5 E).
Etymology The specific epithet is a Latinized adjective referring to a small, sharply pointed distal RTA of the male palp.
