Ommatoiulus SP.4 – Bailey & De Mendonça (1990)

Diagnosis

Similar to O. moreleti (Lucas, 1860) and O. bipartitus with a solenomerite divided into 3 processes and bearing a distolateral lamella and a broad distally expanding paracoxite but different in everything else.

Etymology

The species epithet is a Latin adjective meaning “of the coast” and refers to the affinity of the specie with coastal habitats.

Material examined

Holotype

PORTUGAL: 1 ♂, Faro District, Cape St. Vincent, near Sagres, under low bush, in litter, 10 Apr. 1987, P.T. Bailey leg. (ZMUC), Bailey sp. 4.

Paratypes

PORTUGAL: 1 ♀, 2 juveniles, same data as the holotype; 1 ♂, Faro District, Aljezur Province, Praia de Bordeira, sandy dunes, 37.193917 N, 8.904633 W, alt. 50 m, 12 Apr. 2005, P. Cardoso leg. (ZMUC); 1 ♂, Faro District, Algarve, Cape St. Vincent, 2 Mar. 1981, D. Kime leg. (NHMW 8741).

Description

MEASUREMENTS. Males: L = 25.3–27.8 mm, H = 1.7–2.4 mm, 40–43 PR+2 AR+Telson. Female: L = 37.4 mm, H = 2.9 mm, 42 PR+2 AR+Telson.

COLOUR. Light brown, mostly faded in alcohol (Fig. 12). Prozonites dark brownish, with black sputter denser on the lateral side at the line of ozopores (Fig. 12 B) and forming triangular spots along the middorsal line, metazonites pale whitish and translucent; dorsum with a thin black mid-dorsal line; legs pale brown to yellowish; head light brownish (Fig. 12 A), mouthparts bright yellowish; anal valves with obviously faded black sputter, preanal ring pale (Fig. 12 C). Prozonites with oblique striae; metazonites with regular striation; suture complete, rectilinear but sometimes with a sinus at ozopore level. Anal valves setose with a marginal row of short setae, a submarginal row of longer ones and 1–2 (? perhaps more, broken) setae on the disc. Subanal scale triangular, pointed and setose. Preanal ring with a protruding caudal projection with (5+5) setae and bearing a straight, relatively thick hyaline process.

GONOPODS (Figs 13, 14). Promerite (P) in posterior view slender, subrectangular with parallel margins and slightly curved laterad; mesal ridge (Mr) thin, merging with the mesal margin and distally ending in serrated subapical process; apically almost straight, showing a small hyaline process extending beyond the apical margin; rudimentary telopodite (T) oval, consipicuous on the posterior surface at mid-length of the promerite. Posterior gonopod (Figs 13, 14): Mesomerite (Ms) slender and curved anteriad to nest against the promerite, apically narrowing into a pointed tip; solenomerite (S) large with 3 distinct processes: an anterior process (Sa) the longest, gently narrowing apically and curved anteriad, a median process distally bearing a hyaline lamella (Hl) and a posterior process (Sp) the thinnest and most acuminate apically lodging the opening of the seminal groove 'og'; the seminal groove (g) running from the fovea (F) located at the base of the solenomerite up to og; paracoxite (Px) broad, distally expanding in a hammer-shaped process pointing posteriad; coxa (Cx) large and rounded, protruding distad.
