Lamparia pratensis Shear & Marek, n. sp.

Figs 26–29, 66–68

Types: Male holotype from Grassy Flat Campground, Rt. 199, 5 mi by road E of Gasquet, Del Norte Co., California, 41.8564°N, - 123.8890°W, 700’ asl, collected 25 March 1976 by A. K. Johnson. The specimen is mounted on SEM stub WS35-10, deposited in FMNH .

Etymology: The species epithet is a Latin adjective, meaning “of the meadow,” and refers to Grassy Flats, the type locality.

Diagnosis: Very similar to the L. millicoma n. sp., but distinct in the form of the ninth legs, which lack the expanded coxosternum, the median coxosternal knob, and the curved coxosternal process. Instead, there is a smaller triangular coxosternal process (compare Figs 68 and 71).

Description: Male holotype. Length, 5.0 mm, width 0.45 mm. Two black ommatidia on each side of head. Sixth crests well extended as broad paranota (Figs 26, 27). Telson lobes nearly completely suppressed (Fig. 29, tel). Metazonital setae not seen, absent or concealed by heavy cerotegument. Color after long preservation medium brown. Flasks of third coxae short, when extended posteriorly reaching only to anterior margin of fifth coxae. Other characters as described for genus.

Gonopods (Figs 66, 67) moderately large. Coxae with 3 setae, bulbous, with acute angle distally (Fig. 66, cx). Anterior angiocoxites narrow, erect, with slightly expanded, curved tip, posterior and anterior surface finely fimbriate from base to about half length of coxite (Figs 66, 67, aac). Posterior angiocoxite much reduced; flagellocoxite not sheathed. Flagellocoxite (Figs 66, 67, fc) single, thin, short. Colpocoxite bulbous, shifted anteriomesally, set with a few triangular, fine cuticular teeth (Fig. 67, cc). Ninth legs (Fig. 68) with coxosternum. Coxosternal processes flattened, long, bluntly triangular (Fig. 68, cp), arising near midline. Telopodites (Fig. 68, cp) free, rounded, with projecting posterior lobe. Tenth coxae not much swollen, gland openings anteriodorsal.

Females not collected.

Distribution: Known only from the type locality.
