Diagnosis

Males of Naatlo can be distinguished from those of other theridiosomatid genera by the distally lobed embolus ( Fig. 26E View Fig ; see also Coddington 1986; Dupérré & Tapia 2017) (in contrast with the entire, thin laminated, or distally acute embolus in the other genera). Females of Naatlo can be distinguished from those of other genera by the domed (i.e., elevated ventrally) epigynal plate (absent in other genera except for Epeirotypus ) with an epigynal flap hinged anteriorly (i.e., as an inverted ‘T’) ( Figs 25C View Fig , 27C View Fig ; see also Coddington 1986).

Description

Females of Naatlo have massive proximal copulatory ducts (i.e., more than three times the diameter of the duct’s distal region) with a dorsal patch of gland ducts, and distal copulatory ducts heavily sclerotized (i.e., dark), inserting dorsolaterally posteriorly into the spermathecae ( Figs 25D View Fig , 27D View Fig ). For further genus description details, see Coddington (1986) and Labarque & Griswold (2014).

Remarks

Dupérré & Tapia (2017) suggested that a conductor relatively smaller than the embolus (see “reduced conductor” in Coddington 1986; Dupérré & Tapia 2017) and a broad paracymbium were diagnostic for Naatlo , but those characters are present in all the members of Epeirotypinae (see Coddington 1986).
