Chilelopsis minima is a species of mygalomorph spiders found in Chile. [1] It formerly belonged in the genus Flamencopsis. The specific name was given because it is the smallest member of the tribe Diplothelopsini. [2]
Description
- Female: total length 10.7 millimetres (0.42 in); cephalothorax length 3.77 millimetres (0.148 in), width 2.9 millimetres (0.11 in); cephalic region length 2.4 millimetres (0.094 in), width 2.21 millimetres (0.087 in); fovea width 0.5 millimetres (0.020 in); medial ocular quadrangle (OQ) length 0.36 millimetres (0.014 in), width 0.62 millimetres (0.024 in); labium length 0.36 millimetres (0.014 in), width 0.71 millimetres (0.028 in); sternum length 2.11 millimetres (0.083 in), width 1.61 millimetres (0.063 in). Its cephalic region is wide, short and strongly convex, with its fovea procurved. Its labium possesses no cuspules. A serrula is not visible. Chelicerae: rastellum is formed by short blunt cusps, and it has a fang furrow with 8 large denticles. Its cephalothorax, legs and palpi are a grayish-brownish yellow colour, while its abdomen has a dorsal blackish-brownish chevron. [2]
- Male: total length 7.25 millimetres (0.285 in); cephalothorax length 3.2 millimetres (0.13 in), width 2.48 millimetres (0.098 in); cephalic region length 1.65 millimetres (0.065 in), width 1.5 millimetres (0.059 in); OQ length 0.3 millimetres (0.012 in), width 0.54 millimetres (0.021 in); labium length 0.29 millimetres (0.011 in), width 0.6 millimetres (0.024 in); sternum length 1.84 millimetres (0.072 in), width 1.37 millimetres (0.054 in). Its labium possesses no cuspules, its maxillae having 8 thick but attenuate cuspules. A serrula is absent. Its sternal sigilla is small and shallow, and its sternum is rebordered. Chelicerae: rastellum has thick attenuate setae and a fang furrow with large denticles. Cheliceral tumescence is large and rounded. Color as in female. [2]
Distribution and behaviour
Only known from the provinces of Chafiaral Province and Copiapo, Region III ( Atacama). The type locality is situated near the sea. It is known to habitate thin sand, particularly in narrow Y-shaped burrows. The burrows are usually between 5 and 6 millimetres (0.20 and 0.24 in) wide, and up to 30 centimetres (12 in) deep. During the day, the sand covers the flap-door completely. At night, the burrows are opened (its flap-door turned completely backwards). Spiders stay at the door awaiting prey.
