4, B) trilobate
with outer lobes rounded and much shorter than median lobe; median lobe much elongated and pointed; valves of ovipositor shorter and robust; external lateral projection of lower valves moderately large obtuse angular.
Longitudinally divided Aulichnites Fenton & Fenton, Cruziana burrows/trails (bilobate, d'Orbigny, Didymaulichnus Young, trilobate
) Diplopodichnus Brady, Scolicia Quatrefages XII.
The teeth are not the relatively heavy, transversely compressed trilobate
teeth typical of the extinct S.
Difference in antennae segment (26-29) and fastigium of vertex approximately three time as broad as long; subgenital plate trilobate (Fig.3C) with outer lobes shorter than medium lobe; medium lobe with two spiny ridges converging towards apex, lower valves of ovipositor with external lateral projection forming ridge across ventral surface.
This species is very closely related to H.annulicornis Shiraki in having male cercus with simple apex and posterior margin of pronotum obtuse angular but can easily be separated from the same in having four sulci on pronotum, the prosternal process is bifurcate and the female subgenital plate is trilobate whereas prosternal process conical and subgenital plate with subacute median lobe in H.
Relationships.--Evidence for the placement of Vindullus in Sparassinae includes the presence of only two promarginal teeth in the chelicerae, absence of intermarginal denticles, median hook of trilobate
membrane as large as or slightly larger than lateral projections and a short-toothed female palpal claw (Jager 1998).
Labrum rectangular, with weakly trilobate
This type of cardinalia is characterized by accessory teeth in the ventral valve and a "trilobate
" cardinal process (see below), situated on a platform which is free anteriorly and supported dorsally by two ridges (Fig.
