Notoporus amnoni n.sp.

Material examined

Holotype female (figs 1-9), Cameroon, from Erionomus planiceps Esch. (. Passalidae ); deposited in MIZPAS.

Diagnosis

N. amnoni is similar to N. clypeolus SCHUSTER & SUMMERS : both species have femur I with single macroseta. N. amnoni is distinguished by the presence of single macroseta on femora III and IV, shorter epigynial plate (164 to 195),sternoventral plate (312 to 446), setae dl (354 to 396), d2 (340 to 380) and d3 (332 to 388).

DESCRIPTION

Body oval, longer than wide. Dorsal plate covers whole idiosoma and bears six pairs oflong setae; especially long are dl, d2, d3 and ml ( Tab. I ). All long setae are barbed (fig. 1). Ventrum with broad sternoventral plate. The first pair of sternals longer than the remaining ones. Postgenital setae placed near posterior margin of sternoventral plate. This plate considerably widened behind coxae IV. Epigynial plate oval; its posterior margin unvisible. Paranal setae (pa) is very long and barbed (fig. 2). Tectum with lateral rami broadened (fig. 3), mesal process bifurcates, delicately fringed.

Genu and femur of leg I each with one barbed macroseta and the same seta on femur; seta on femur I somewhat longer than seta on genu I (fig. 4). Terminala over twice longer than subterminala ( Tab. I ). Leg II with one barbed macroseta on femur (fig. 5). Legs III-IV each bears on femora and genua one barbed macroseta (fig. 6).

Palps with short and nude setae, except the dorsal side of femur; palpfemoralais barbed and much longer than the remaining ones (fig. 7).

Cheliceral spur curved, smooth (fig. 9). Malae externae relatively massive of moderate length -60 Pm, malae internae comprise two long processes (fig. 8). Measurements are given in Tab. I .

Remarks

SCHUSTER & SUMMERS (1978) mentioned three genera belonging to the Diarthrophallinae for Africa. Species of the genus Notoporus are associated with passalid beetles belonging to the genus Erionomus . At present only two species of Notoporus are known. N. amnoni n.sp. was obtained from thesame host as N. asperatus SCHUSTER & SUMMERS but from the other territory. N. amnoni has character untypical for this genus: femora III and IV each have only one macroseta. This character is typical for the genus Tenuiplanta SCHUSTER & SUMMERS but this genus is known from Mexico and Central America. The remaining characters are typical for the genus Notoporus . In this case N. amnoni n.sp. is provisionally include to the Notoporus . The new species can be distinguished from both known Notoporus by only one macroseta on femora III, IV. From two known species of Tenuiplanta it can be separated: 1) from T. crossi (HUNTER & GLOVER) by distinctly longer ultralong dorsal setae and the presence of six pairs of long setae on dorsal plate (in T. crossi only four pairs), 2) from T. polypora SCHUSTER & SUMMERS by the presence of six pairs of long setae on dorsal plate (in T. polypora five pairs) and shorter ultralong dorsal setae. From both species it differs by the shape of tectum.

Etymology

The name of the species has been derived from the name Amnon
