Eumanota vilkamaai sp. n.

Figs 1 D, E, 14 A, B, C

Male. Colour. Head pale brown. Antenna unicolorous pale brown. Mouthparts unicolorous yellowish. Thorax brown, lateral parts slightly paler than scutum and scutellum. Wing with basal half nearly colourless yellowish, apical half infuscated ( Fig. 1 E). Legs pale yellowish, apices of coxae, trochanters, extreme base and apical third of femur 3 infuscated; in the mount also femur 1 and 2 appear brownish, but we assume it due to their contents. Abdomen unicolorous pale brown (after treatment with KOH), hypoproct and cerci whitish. Setae and other vestiture vary from pale yellowish to dark brown or blackish, largely depending on their thickness. Head. Similar to E. hilleviae (Hippa et al. 2004: fig 3a). Ultimate palpomere of maxillary palpus 7.3 times longer than penultimate. Antennal flagellomere 4, Fig. A. Thorax. Similar to E. hilleviae (Hippa et al. 2004: fig 4a). Anepisternum with ca 130 weak setae and 1 strong setae on posterior part; anterior basalare with ca. 10 weak and 2 very strong setae; preepisternum 2 non-setose; laterotergite with ca 70 weak setae intermixed with 10 strong ones; episternum 3 non-setose. Legs as usual, basal part of hind tibia similar to E. leucura (Hippa et al. 2004: fig 3e). Wing, Figs 1 D, E. Hypopygium, Figs 14 B, C, D. No sternite 9 identifiable. Gonocoxae fused, postero-medially separated by a cleft which is almost half length of gonocoxa. Ventral mesial and apical margin of gonocoxa simple, apicomesial corner rounded, not lobe-like. Dorsal mesial margin of gonocoxa simple, convex; at middle of mesial margin, on more ventral level, there is a sclerite with setae. Paramere long and narrow, extending to level of posterior margin of gonocoxa, apically with short setae directed mesiad. Aedeagus with a membranous trichose apical part extending posteriorly as far as apex of paramere, aedeagal apodeme looped, a pair of longitudinal rod-like structures medio-dorsally on the aedeagus. Ventral part of hypoproct (sternite 10) with nearly 100 setae, lobe-like posterolateral parts with ca 10 setae each, posteriormost stronger than remainder. Tergite 9 as usual. Cerci as usual, baso-medially fused.

Female. Similar to male. Baso-ventral part of tibia 3 simple. Apical part of abdomen similar to fig. 4a in Hippa et al. 2004.

Discussion. E. vilkamaai is similar to E. malukuensis Søli ( Indonesia, Maluku Utara) and E. jani Papp ( Papua New Guinea, Madang province), but is distinguished from them by the different shape of the gonostylus. In E. vilkamaai the gonostylus is short, only slightly longer than broad, and it widens from base towards the apex, in M. malukuensis the gonostylus is about three times longer than broad while in E. jani it is about twice as long as broad and in both species it narrows towards the apex. All the three species are characterized by two short, rather strong setae at the apical margin of the gonostylus and slender and long parameres, unlike the other described Eumanota .

Etymology. The species is named after the Finnish sciaroidologist Dr. Pekka Vilkamaa, one of the few students of the Manotinae .

Types. Holotype. Male. PAPUA NEW GUINEA, Morobe Province, Lakekamu basin, Tekadu, 470 m, Malaise trap close to Yenina river, 17–20.xi.1999, leg. H. Hippa, R. Norberg, D. Borisch (in SMNH). Additional material. 1 female with same data as holotype (in SMNH).
