Diaparsis (Diaparsis) kanyawara Khalaim & Sääksjärvi, 2014

Khalaim, Andrey I., Sääksjärvi, Ilari E. & Roininen, Heikki, 2014, Three new Afrotropical species of Tersilochinae (Hymenoptera: Ichneumonidae) from the Kibale National Park, Uganda, Zootaxa 3794 (4), pp. 536-544 : 538-539

Diaparsis (Diaparsis) kanyawara Khalaim & Sääksjärvi , sp. nov.

( Figs 1 , 3–8 )

Comparison. The new species is similar to D. interstitialis , D. nebulosa and D. sinuator sp. nov. as only these four species of the genus have a conspicuous white band on the flagellum. Diaparsis kanyawara sp. nov. differs from these species by the longer, slenderer and apically clavate flagellum with a white band situated near its centre and 13 apical flagellomeres being black ( Figs 1 , 5 ). In addition, the new species does not possess a foveate groove on mesopleuron ( Fig. 6 ). Diaparsis kanyawara sp. nov. also differs from D. interstitialis by the second recurrent vein being postfurcal, from D. nebulosa by the shorter basal keel of propodeum and longer ovipositor, and from D. sinuator sp. nov. by the shorter malar space, propodeum with distinct basal keel ( Fig. 7 ), evenly upcurved ovipositor ( Fig. 8 ) and yellow hind coxa.

Description. Female. Body length 6.2 mm. Fore wing length 4.2 mm.

Head strongly rounded behind eyes in dorsal view; temple 0.45× as long as eye width; eyes strongly prominent in dorsal view ( Fig. 4 ). Antenna 1.1× as long as fore wing ( Fig. 1 ); flagellum very slender, slightly clavate at apex ( Fig. 5 ), with 28 segments; subbasal and mid flagellomeres 2.5–3.5× as long as broad, subapical flagellomeres as long as broad. Mandible slender, with upper tooth much longer than lower tooth. Malar space half as long as basal width of mandible ( Fig. 3 ). Clypeus broad, lenticular, weakly convex in lateral view, 2.8× as broad as long, punctate and finely granulate in upper half and smooth in lower half. Face and frons finely and very densely punctate on granulate background (punctures mostly indistinct because of granulation), dull. Vertex and temple granulate, with fine and moderately dense punctures. Occipital carina complete. Hypostomal carina absent, surface polished.

Mesoscutum finely granulate, with dense distinct punctures, dull. Notaulus absent. Mesopleuron densely punctate, granulate, dull. Foveate groove completely absent ( Fig. 6 ). Propodeal spiracle separated from pleural carina by 2.0 diameters of spiracle. Propodeum densely punctate on granulate background, dull, with distinct basal keel which is 0.73× as long as apical area ( Fig. 7 ); apical area pointed at right angle anteriorly, flat; apical longitudinal carinae anteriorly weak but reaching transverse carina.

Fore wing with first abscissa of radius slightly curved, longer than width of pterostigma. Metacarp somewhat not reaching apex of fore wing. Second recurrent vein postfurcal. Intercubitus moderately long. Hind wing with nervellus slightly reclivous.

Legs slender. Hind femur 5.1× as long as broad and 0.78× as long as tibia. Spurs of hind tibia slender, slightly curved apically. Tarsal claws long, not pectinate.

First metasomal tergite slender, round in cross-section at level of mid length of petiole, mostly smooth, with striae before glymma, 4.1× as long as posteriorly broad, with distinct glymma somewhat behind its middle. Second tergite 1.65× as long as anteriorly broad. Thyridial depression very narrow, more than 3.0× as long as broad. Ovipositor upcurved, with very shallow dorsal subapical depression ( Fig. 8 ); sheath about 2.3× as long as first tergite.

Head, mesosoma (including tegula) and first metasomal segment black; lower half of clypeus, palpi and mandible (except blackish teeth) brownish yellow. Antenna with scape and pedicel brownish yellow, flagellum black with a median white band that covers flagellomeres 11–15 (13 apical flagellomeres black). Pterostigma dark brown. Legs brownish yellow, hind tibia dorsally and tarsus infuscate. Metasoma behind first tergite brownish yellow ventrally to dark brown dorsally, hind margins of tergites 2+ yellow banded dorsally.

Male. Unknown.
