Epilineutes Coddington, 1986

Epilineutes Coddington, 1986: 74 .

Type species Adrasta globosa O. Pickard-Cambridge, 1896 ; by original designation.

Diagnosis

Males of Epilineutes can be distinguished from those of other theridiosomatid genera by the thin, elongated, distally acute, median apophysis retrolateral projection extending anteriorly ( Fig. 59E ; see also Coddington 1986) (absent in other genera). Females of Epilineutes can be distinguished from those of other genera by the notched epigynal posterior margin ( Coddington 1986: fig. 173) (absent in other genera).

Description

Males of Epilineutes have tripartite embolic apophysis, retrolaterally finger-printed conductor, and sub-rectangular median apophysis with denticles ( Fig. 59D–F ; Coddington 1986: figs 189–190). Females of Epilineutes have a dorsal scape protruding from beneath the notched epigynal plate transverse groove ( Fig. 60D ; Coddington 1986: fig. 173), and irregular membranous copulatory ducts inserting ventromedially posteriorly into spermathecae ( Fig. 60D ). For genus description details, see Coddington (1986) and Labarque & Griswold (2014).
