Holotype

MADAGASCAR • ♂; “MADAGASCAR: Province Fianarantsoa, Parc National Ranomafana, radio tower at forest edge, elev 1130 m, 28 Nov – 6 Dec 2001, 21°15.05′ S, 47°24.43′ E, coll: M. Irwin, R. Harin’Hala, California Acad of Sciences , malaise, mixed tropical forest, MA-02-09B-05”; CAS.

Description

Length of male 8.7 mm (female unknown). Dorsum dull stramineous with sparse symmetrical dark brown markings, face unmarked, venter of thorax unmarked, pronotum with several symmetrically arranged black spots anteriorly, forewing infused with reddish pigment, front and middle tibia with indistinct brown bands dorsally, macrosetae of all legs with dark brown to black bases, hind tibia with some dorsal macrosetae black. Crown flat in profile, marginal rim relatively thick, not forming shelf over frontoclypeus, ocelli nearly touching anterior margin. Forewing with few or no supernumerary crossveins, inner apical cell elongate and narrow. Hind tibial rows PD, AD and AV with 21, 12 and 10 macrosetae, respectively. Style apophysis curved gradually dorsad over most of length, tapered to small, foot-like apex extended slightly dorsomesad. Aedeagus with atrium V-shaped, with weakly sclerotized plate between arms of V; shaft curved strongly dorsad, with pair of acuminate lateral spines arising laterally near midlength, bowed slightly laterad and extended nearly to apex, closely parallel to shaft in posterior view, shaft slightly ovoid in posterior view, shaft apex tapered and slightly emarginate, gonopore apical.

Remarks

The male genitalia of this species closely resemble those of P. olivacea sp. nov., but the aedeagal shaft is ovoid rather than parallel-sided in posterior view and the lateral spines are bowed outward rather than straight. Pseudomarganana olivacea sp. nov. is also considerably larger and lacks red pigment on the forewing.
