Heriaeus copricola View in CoL sp. n.

Figs 4 View Figs 1–9 , 22–25 View Figs 22–29 , 59 View Figs 57–59

Etymology: From Latin copros (dung) and colere (to dwell in). The species name was suggested by Dr R.F. Lawrence (in litt.), who marked the type specimens as being a new species but did not publish its description.

Diagnosis: The species is recognized by the combination of long, slender, blunt abdominal setae and the epigyne having a shallow hood over a small round opening ( Fig. 24 View Figs 22–29 ), with the internal organs visible as two light brown kidney-shaped structures below the hood ( Fig. 24 View Figs 22–29 ). The embolus of the male palp is short, winding less than once around tegulum, with the tip slender and straight; VTA broad ( Fig. 23 View Figs 22–29 ); RTA with short distal tooth when viewed laterally ( Fig. 22 View Figs 22–29 ). The male palp resembles that of H. zanii sp. n. ( Fig. 53 View Figs 53–56 ) but differs in the shape of the RTA, having a single tooth and the uniquely shaped abdominal setae ( Fig. 4 View Figs 1–9 ).


Female (allotype).

Size: TL 4.88, CL 2.31, CW 2.04. Colour: Carapace with two longitudinal brown bands extending to PEs; setae brown; clypeus w ith brown marks; sternum white along edge; chelicerae yellow-brown; eye region white. Abdomen beige, mottled with white, with faint transverse lines posteriorly as well as a number of dark brown markings; venter white with fine hairs, with some brown spots laterally. Legs beige with brown spot on proximal end of tibiae and distal ends of metatarsi III and IV; some white mottling on coxae. Carapace: Eye measurements: AME–AME 0.14, ALE–AME 0.30, PME–PME 0.22, PLE–PME 0.31, AME–PME 0.24, MOQL AME–PME 0.31, MOQAW AME– AME 0.36, MOQPW PME–PME 0.28.

Abdomen: Oval, truncated anteriorly, with long slender either transparent or pale brown setae with blunt tips; darker brown setae along lateral edge of dorsum. Epigyne: Hood shallow with small round opening, internal organs visible as two pale brown kidney-shaped structures, touching anteriorly and narrower posteriorly ( Fig. 24 View Figs 22–29 ); copulatory ducts large and bulbous anteriorly, tubular posteriorly ( Fig. 25 View Figs 22–29 ).

Male (holotype).

Size: TL 3.88, CL 1.89, CW 1.70. Colour: Carapace with two longitudinal brown bands extending to PEs and into eye region; setae brown ( Fig. 4 View Figs 1–9 ); chelicerae yellow-brown; clypeus with brown marks; eye region white. Abdomen brown, mottled with white; laterally with some brown marks; setae on abdomen dark brown with dark spots at their bases laterally; venter white, covered with fine hairs. Legs yellow­brown, with white spot on each coxa. Carapace: Eye measurements: AME–AME 0.23, ALE–AME 0.53, PME–PME 0.23, PLE–PME 0.30, AME–PME 0.21, MOQL AME–PME 0.29, MOQAW AME–AME 0.28, MOQPW PME–PME 0.29.
