Chaetotaxy: 3 strong orb, the anterior slightly reclinate, not at all inclinate, middle and posterior orb reclinate and lateroclinate; pvt distinct and crossed; 1 vti and 1 vte strong; oc short and strongly lateroclinate; about 8 short setulae across middle of fr.
The
chaetotaxy of the metasoma is quite similar between the species of the bonariensis group and B.
Tibiotarsus
chaetotaxy formula follows Deharveng (1983), and is expressed as: total number of chaetae (number of chaetae in row C, number of chaetae in row B, number of chaetae in distal rowA+T), for example 17 (1, 7, 9).
Chaetotaxy: 1 pprn, 1 posthu, 1 ihu, 2 ntpl, 0+4 ia, 2+4 acrs, 3+4 dc only the posterior one well-developed, prpl not seen, 1 pa, 2 pairs of marginal scut, 1 katepisternal, 1 anepisternal, all setae pale yellow.
An additional drawback is the non-fluorescent nature of setae and macrosetae, making this technique unsuitable for investigation into
chaetotaxy. Interestingly, the base of some setae and the areoles of trichobothria typically fluoresce more brightly than the surrounding surfaces and this property can assist in the location of trichobothria.
However, based on
chaetotaxy of legs, Nilsson [9] postulated that larvae of Hydroporinae are more primitive than those of C.

chaetotaxy follows Nayrolles (1991), trichobothria and surrounding setae as in Richards (1968).
This study uses a novel morphological character set, the
chaetotaxy of lycosid larvae (presence and arrangement of setae and slit organs), to infer systematic information on seven species of wolf spiders that are currently listed in three subfamilies: Lycosinae [Alopecosa pulverulenta (Clerck 1757), Hogna antelucana (Montgomery 1904), Rabidosa rabida (Walckenaer 1837), Trochosa ruricola (DeGeer 1778)], Piratinae [Hygrolycosa rubrofasciata (Ohlert 1865), Pirata hygrophilus (Clerck 1757)], and Sosippinae (Sosippus californicus Simon 1898).

We also documented other traits that are very characteristic of lepidopteran larvae, in particular the body
chaetotaxy and the number and arrangement of the crochets found in the prolegs.
