GENUS IARDINIS SIMON 1899 View in CoL
( FIGS 135A, B View Figure 135 , 144C View Figure 144 )
Iardinis Simon, 1899: 87 View in CoL .
Type species by original designation: Iardinis weyersi Simon 1899: 87 (nomen dubium, female type and only specimen lost);
Levi & Levi, 1962: 22 (considered incertae sedis); Forster & Platnick, 1977: 5 (considered nomen dubium); Brignoli, 1970: 1426; 1978: 250; 1980: 731 (provisional transfer to Mysmenidae View in CoL ).
Iardinus, Gertsch, 1960a: 8 (lapsus calami, transferred from Theridiidae View in CoL to Symphytognathidae View in CoL s.l.).
Familial placement: Symphytognathidae . The type and only specimen of the type species ( Iardinus weyersi ) from Sumatra was described by Simon in 1899, but has been considered lost by the arachnologists that have tried to examine the type material ( Gertsch, 1960a; Levi & Levi, 1962; Brignoli, 1970, 1978, 1980; Forster & Platnick, 1977). The vial from the Paris Museum (MNHN) with the original label that should have housed the type material is actually empty (L. Lopardo & G. Hormiga, pers. observ.). Nevertheless, two additional species have been described for the genus: Iardinus martensi Brignoli, 1978 from Nepal, and Iardinus mussardi Brignoli 1980 from India (holotype examined, see also Figs 135A, B View Figure 135 , 144C View Figure 144 ). Both species are exclusively known from their male type specimens. To add to the enigmatic status of the genus, the original vial containing the type and only specimen of I. martensi instead contained a female anapid (L. Lopardo & G. Hormiga, pers. observ.), and therefore its morphology had to be scored from the literature.
Nonetheless, both Iardinis species included in the 65- and 70-taxa data sets (i.e. I. martensi and I. mussardi ) are more closely related to Symphytognathidae than to Mysmenidae . Morphologically these species have none of the synapomorphic features of Mysmenidae , and thus, as with Crassignatha , their placement in a different family was expected. They differ from Mysmenidae in the absence of femoral spots (at least in I. mussardi ), absence of tibial or metatarsal clasping spines on leg I, dorsal (instead of ventral) cymbium, absence of cymbial structures (e.g. primary conductor, process, and paracymbium), and presence of median apophysis. They further share with Symphytognathidae the loss of anterior median eyes, thick setae on the dorsal part of the abdomen, absence of cheliceral denticles, loss of colulus, and absence of palpal patellar or tibial apophyses.
