Type species. Arachnopsis nietneri Saussure, 1878

Other species included. A. annulicornis Chopard, 1936 , A. bicolor Chopard, 1928 , A. brevipalpis Chopard, 1969 , A. lepidus Chopard, 1969 , A. microphtalmus Chopard, 1929 (see Chopard 1969), Phalangopsis amboinensis Karsch, 1886 (see Gorochov 1996), Kempiola maindroni Chopard, 1969 , A. aureopubescens Wiendl, 1970 , A. istrapura Gorochov, 2003c , A. jacobsoni Chopard, 1924 .

Distribution. Southern India (Coromandel coast, Kerala), Sri Lanka, Java. One species described from Brazil, probably erroneously.

Diagnosis. Size small to large. Head not very long. Eyes greatly protruding ( Fig. 2 B, except in A.

microphthalmus : eyes flat and reduced). Fastigium much narrower than the scape ( Fig. 2 B). Ocelli set in an acute triangle (lacking in A. microphthalmus ), the distance between lateral ocelli much shorter than the distance between one lateral and the median ocelli. Maxillary palpi very elongate, with joint 5 distinctly longer than joint 3. Pronotum transverse ( Fig. 2 A, D). Mesonotum short, metanotum as long as the pronotum ( Fig. 2 A, E). All legs long and thin ( Fig. 2 A). TI without tympanum. TIII with four pairs of alternate subapical spurs (five pairs mentioned by Chopard in A. bicolor ), the outers longer than the inners; three inner and three outer apical spurs, the median the longest on both sides: the inner median spur very long ( Fig. 1 I), the outer median spur much longer than the dorsal spur ( Fig. 1 J); TIII serrulated on both sides. Tarsi all long, hind basitarsi with few dorsal spines. Male and female apterous. Male metanotum and tergites lacking glandular structures; TIII spurs not modified. Male genitalia resembling those of Zacla Gorochov, 2003a (median process of pseudepiphallus short and straight, slightly shorter than lateral lobes, rami very short, ectophallic fold sclerotized laterally, endophallic sclerite long, bearing a crest-like apodeme). Female genitalia horse-foot shaped, with a plicated basal membrane, and a thick distal sclerite distinctly furrowed at apex ( Fig. 1 G, H).

Habitat. Unknown.
