Description

Maraplia schusteri Shear & Marek, n. sp.

Figs 10, 11, 55–57

Types: Male holotype and two male paratypes from near Stringtown Hill, NE of Oroville, Butte Co., California, 39.5219°N, - 121.3909°W, 1440’ asl, collected 9 February 1956 by R. O. Schuster. Types deposited in FSCA. Parts of holotype and one paratype on SEM stub WS35-4.

Etymology: The species is named for entomologist Robert O. Schuster (1927–1989).

Diagnosis: Distinct from the two other species of Maraplia n. gen. in the form of the gonopods. Maraplia schusteri n. sp., has long, thin, and evenly curved angiocoxites, rather than the sharply deflexed, relatively short anterior angiocoxites seen in the other species (Figs 10, 55, 56, aac). The coxal process is not flattened and platelike but narrower and distinctly bifid (Fig. 55, cp).

Description: Male holotype. Length 3.5 mm, width about 0.32 mm. Two black ommatidia on each side of head. Color white. Sixth crests about twice height of C5, as short paranota. Telson lobes obscure. Other characters as for genus.

Gonopods (Figs 10, 55, 56) small, compact. In lateral view, coxa (Fig. 55, cx) with about 6 or 7 setae, coxal process narrow, distally bifid, anterior branch longer, posterior branch slightly recurved (Fig. 55, cp). Anterior angiocoxite (Figs 10, 55, 56, aac) narrow, long, evenly curved, apically acute, with smaller basal triangular tooth. Posterior angiocoxite strongly reduced to single blunt rod, apparently not sheathing the very short, straight flagellocoxite. Colpocoxite (Figs 55, 56, cc) shifted anteriomesally, with anterior branch densely fimbriate, posterior part swollen, with a few small, fine triangular fimbriae. Ninth legs (Fig. 57) with mesal coxosternal process low, triangular (Fig. 57, cp), telopodite fungiform (Figs 10, 57, t 9), bearing mesal process set with 6 or 7 ensiform setae and second curved, roughly triangular posterior process. Tenth leg coxae slightly enlarged, with glandular openings.

Females not collected.

Distribution: Presently known only from Butte County, California.
