PLATNICK, NORMAN I., 2000, A Relimitation And Revision Of The Australasian Ground Spider Family Lamponidae (Araneae: Gnaphosoidea), Bulletin of the American Museum of Natural History 2000 (245), pp. 1-328 : 316-318

Paralampona , new genus

TYPE SPECIES: Paralampona domain , new species.

ETYMOLOGY: The generic name refers to the falsely lamponine appearance of these spiders.

DIAGNOSIS: The absence of a chevroned abdomen usually separates members of this genus from those of Pseudolampona , as do the absence in males of thick setae on the sternum and a median apophysis on the palp, and in females of lateral pockets on the epigynum.

DESCRIPTION: Small spiders, total length of males 1.3–2.1, of females 1.7–2.5. Carapace light orange, pars thoracica coated with long setae originating from anastomosing rows of low tubercles, pars cephalica elevated, elongated, lightest (especially posteriorly), with few setae; thoracic groove short, longitudi­ nal, situated back at about four­fifths of carapace length. Eight eyes in two rows, posterior medians largest, others subequal in size; anterior medians circular, dark, other eyes light, laterals oval, posterior medians irregularly oval, flattened; from above, anterior eye row slightly recurved, posterior row slightly procurved, from front, both rows strongly procurved; anterior medians separated by almost their diameter, by about their radius from anterior laterals; posterior medians separated by almost their radius, by almost their diameter from posterior laterals; anterior and posterior laterals separated by less than their diameter; median ocular quadrangle wider in front than in back, about as long as wide in back. Chelicerae, sternum and mouthparts light orange; chilum small, triangular, accompanied by second, small, oval posterior chilum; chelicerae with distinct lateral boss, promargin with series of short setae originating in line along base of fang plus one long, thick seta originating closest to fang, immediately bent at 90 degree angle, extending to median line; promargin with single large tooth and one or two denticles, retromargin with two tiny denticles near base of fang. Labium elongate, triangular, with broad distal tip, truncated posteriorly, distinctly depressed medially. Endites obliquely depressed, without sharply demarcated, deep groove along margin near labium; serrula present, teeth in single row. Sternum very slightly elevated, with rebordered lateral margins, not expanded anteriorly, with extensions to and between coxae; surface smooth, males without patch of short, thick, dark setae posteriorly. Two epimeric sclerites on each side, one opposite palpal endites, one surrounding all coxae, not reaching sternal triangles, not fused to carapace. Pedicel composed of two small, flat dorsal sclerites and almost rectangular sclerite covering venter and sides.

Abdomen without dorsal or anterior scutum in either sex; cuticle with thick setae; epigastric scutum accompanied posterolaterally by tiny, inconspicuous pair of narrow, transverse, invaginated sclerites; sclerites separated by membranous lobe, sometimes continued as slight sclerotization around lateral edge of epigastric scutum; colulus rep­ resented by pair of strong setae; posterior spiracle not on distinct sclerite. Anterior lateral spinnerets tubular, separated by almost their diameter, cuticle representing distal, second spinneret segment restricted to semicircle surrounding major ampullate gland spigots (piriform gland spigots surrounded only by soft cuticle); posterior median spinnerets small, tubular, without anteriorly expanded tips; posterior lateral spinnerets twosegmented.

Legs spineless; most surfaces with thin setae; coxae not notably tuberculate; anterior coxae with protuberant posterolateral corners; trochanters unnotched; anterior metatarsi and tarsi without scopulae; posterior metatarsi without distal preening brushes; posterior tarsi not scopulae; tarsi with two short claws, claw tufts reduced to just few setae; trichobothria present on distal segments. Female palpal tibia and tarsus without spines; female palpal tarsus with small claw.

Male palp with retrolateral tibial apophysis, sometimes with modified femur; cymbium unmodified; tegulum not expanded; embolus prolaterally or medially situated, elongated, accompanied by membranous conductor; median apophysis absent. Epigynum simple, usually with small anterior hood and pair of globose spermathecae.
