Cosmocomopsis sevae (Risbec) , comb. n.

( Figs 62–66 , 74–82 )

Triapitsyn, 2010: 13 [transferred to Gonatocerus (Lymaenon) , distribution]

Huber et al., 2010: 233 (invalid lectotype designation because ICZN Rules 74.7.2 and 74.7.3 not followed).

Diagnosis. Cosmocomopsis sevae is distinguished from the two other species by having two funicle segments, fl5 and fl6, white ( Fig. 62 ), the mesosomal midlobe orange in anterior half, and the petiole dorsally yellow or light yellow. Cosmocomopsis flopsis has three funicle segments (fl5–fl7) white, and C. mopsis has two (fl6 and fl7) white, the mesoscutum anteriorly with a distinct brown spot, and the petiole brown.

Description. FEMALE. Body length 2125–2380 (n=5, non-type specimens). Colour. Body yellow, with lighter and darker shades; trabeculae and most of flagellum brown, fl5 and fl6 white; darker yellow areas are vertex, spots on pronotum sublaterally and laterally, anterior third or half of mesoscutum, axillae, and transverse bands on terga of gt2–gt7. Head. Head width 625 (n=1). Antenna. Funicle segments fl4–fl8 (also fl 3 in lectotype) each with at least 4 mps. Antennal measurements (n=1), length/width (ratios of flagellar segments): scape 678/77, pedicel 108/ 56, fl1 88/46 (1.91), fl2 150/50 (3.00), fl3 161/53 (3.04), fl4 158/60 (2.63), fl5 160/66 (2.42), fl6 146/66 (2.21), fl7 134/ 69 (1.94), fl8 122/78 (1.56), clava 402/100 (4.02). Mesosoma. As in generic description. Wings. Fore wing length (n=1) 2290, width 608, length/width 3.77, longest marginal seta 122. Hind wing (n=1) length 1727, width 62, longest marginal setae 144. Metasoma. Ovipositor sheath length (n=1) 808, distinctly shorter than metatibia length (~ 870).

MALE. Body length 1587 (n=1). Colour. As in generic description. Antenna. Measurements (n=1): scape length/width 187/160, pedicel length/width 72/54, flagellar segments length: fl1 224, fl2 275, fl3 271, fl4 253, fl5 266, fl6 251, fl7 252, fl8 239, fl9 259, fl10 237, fl11 318; total flagellar length 2846; fl6 length/width 3.14, with about 15 mps. Metasoma. Genitalia as in generic description ( Fig. 74 ).

Material examined. Lectotype ♀ ( MNHN). The specimen on a slide is redesignated (validly) here as lectotype to avoid confusion about the status of the type specimen of this species. The lectotype ( Figs 62–66 ) is in Canada balsam on a slide labelled 1.” 860. Ex ponte Orthoptère [followed by illegible word] feuille sur [sentence incomplete]”. 2. “ Ooctonus sevae Risbec Lectotype ♀”. 3. “Deux paralectotypes remontés sur pailletttes par J. Huber, 2005”. 4. [on back of slide] “ Ooctonus sevae Risbec ”.

Paralectotypes. 2 ♀ mounted on cards, with same data as lectotype. Risbec’s original description indicated that the rearing was from 4.v.1951, with adult emergence (3 females) on 7.v.1951 from Orthoptera laying [“ponte”] on the edge of a leaf of Seva [local name of a plant].

Despite a certain amount of variation in antennal proportions, a much fainter brown area just beyond the venation, and absence of mps on fl3, I assign nine more specimens to C. sevae , from the following localities, with some repetition of Triapitsyn (2010) locality records. More material is needed to assess variation better and determine whether a species complex exists. MADAGASCAR. Antsiranana (Diego Suarez). 7 km N. Joffreville, 12°20'S 49°15'E, 360m, 7–27.iv.2001, R.
