( Fig. 14 )

Diplura sexfasciata Schiapelli & Gerschman, 1945: 177 , pl. VI.

Linothele sexfasciata – Raven 1985: 74.

TYPE MATERIAL. — Holotype. Venezuela • ♀; Caracas ; III.1936; J. Vellard leg.; MACN No. 800 examined.

TYPE LOCALITY. — Caracas, Venezuela.

DISTRIBUTION. — Only known from the type locality.

DIAGNOSIS. — The female of Linothele sexfasciata resembles L. monticolens , but can be distinguished from it by its pseudo-segmented leg tarsi, alongside its distribution.

DESCRIPTION

Male

Unknown.

Female

CT = 10. MC = 25-30. Colouration in alcohol: Overall pale yellow; opisthosoma dorsally with distinct pattern consisting of complete chevrons, see Schiapelli & Gerschman (1945: Pl. IV), ventral pattern absent from opisthosoma; maculae absent. Clypeus: narrow. Preening-combs absent. Leg tarsi pseudo-segmented. Spinnerets: apical segments of the PLS rigid. Spermatheca:consisting of two stalks with one prolateral and one dorsal vesicle at 1:3A, see Figure 14A.

REMARKS

The holotype is partly disarticulated with no leg, nor pedipalp still attached to the prosoma. Fortunately, one leg II has been dissected including coxa with other coxae still attached to the prosoma. We therefore could evaluate the scopula on tarsus II, which is divided. On no other leg an undivided scopula or preening-combs could be observed. Schiapelli & Gerschman (1945: Pl. VI) show a distinct dorsal pattern consisting of chevrons, which is still evident in the holotype.

NATURAL HISTORY

Unknown.
