Etymology. The specific epithet is a patronym in honour of Stewart and Jarmila Peck, who collected many specimens of this (and other micropholcommatid) species in 1980, during AMNH-sponsored field work in south-western Western Australia.

Diagnosis. Males of Raveniella peckorum can be distinguished from R. hickmani by the longer, distally-curled embolus ( Fig. 77 ), and from R. luteola by the absence of a terminal, spur-like extension on the evaginated tegular ridge ( Fig. 77B ). Females can be distinguished from all other described congeners by the cylindrical receptacula and spherical morphology of the spermathecae ( Fig. 75D ).

Description. Holotype male: Total length 1.16. Carapace 0.59 long, 0.45 wide. Abdomen 0.63 long, 0.51 wide. Leg I femur 0.45. Cephalothorax, legs dark tan-yellow; abdomen dark olive-grey. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.6x diameter of ALE; PME separated by their own diameter. Chelicerae each with large, bulging anterior projection; promargin with three peg teeth. Legs relatively short (leg I femur-carapace ratio 0.76); distal, prolateral macroseta present on tibia I. Abdomen oval, covered with hairlike setae; dorsal scute and lateral sclerotic strips absent. Pedipalpal patella with retrolaterally-directed, hooked lRPA, small, conical distal apophysis, larger, subtriangular terminal apophysis and ornate, ridged cuticular microstructure; tegulum smooth, with curved, marginal ETR; embolus very long (length >> 5× width), extending posterior to patella, curling distally to form a three-quarter revolution; cymbium unmodified with three long posterior macrosetae ( Fig. 77B ).

Allotype female: Total length 1.22. Carapace 0.60 long, 0.43 wide. Abdomen 0.74 long, 0.59 wide. Leg I femur 0.45. Cephalothorax, legs tan-yellow; abdomen tan-grey. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.6x diameter of ALE; PME separated by slightly less than their own diameter. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 0.75); macrosetae absent. Abdomen oval, covered with hair-like setae; dorsal scute and lateral sclerotic strips absent. Pedipalp entire, five-segmented. Epigyne with distinctive external morphology ( Fig. 76D ); receptacula cylindrical, with spherical spermathecae; insemination ducts membranous, with complex, convoluted trajectory and multiply-looped distal portion; fertilisation ducts filiform ( Fig. 75D ).

Distribution. This species is found throughout the south-western Australian ‘High Rainfall Province’ (see Hopper and Gioia 2004), from Two Peoples Bay Nature Reserve near Albany to the Avon National Park, north of Perth, with outlying populations in the Porongurup and Stirling Range National Parks. It is ubiquitous in the tall eucalypt forests of the Darling Escarpment and south coast, and is also found throughout the southern Swan Coastal Plain (including Rottnest Island), north to Neerabup National Park.

Remarks. Raveniella peckorum is one of several species of Raveniella known from south-western Western Australia (M. Rix, unpubl. data). It was included in the molecular phylogenetic analysis of Rix et al. (2008) as “ Textricella sp. WA”.
