Gonatocerus (Cosmocomoidea) masneri Yoshimoto, 1990

( Figs 369–371)

Gonatocerus masneri Yoshimoto 1990: 40 (listed in masneri species group), 88–89, 131, 137, 148 (illustrations [see “Comments”]). Type locality: El Río, La Vega, Dominican Republic.

Gonatocerus masneri Yoshimoto : De Santis & Fidalgo 1994: 125 (catalog).

Type material examined. Holotype female [ CNCI] on point labeled: 1. “ Rep. Dominicana , El Rio (La Vega), 17.III.1978, L. Masner, 1,000 m, sweeping”; 2. (red) “ HOLOTYPE Gonatocerus masneri Yosh. CNC No . 18474”. The holotype ( Fig. 369) is in good condition, complete. Allotype male [ CNCI] on point labeled: 1. “ Rep. Dominicana , Santo Domingo, 14.VIII.78, L. Masner ”; 2. (green) “ SLIDE No . 78.07.27.13”; 3. (red) “ ALLOTYPE Gonatocerus masneri Yosh. CNC No . 18474”. One antenna from the allotype specimen is mounted on slide [ CNCI] labeled: 1. “ Gonatocerus masneri Yoshimoto ♂ antenna Allotype ”; 2. “Can. Nat. Collection No . : 78.07.27.13 Loc. Rep. Dominicana Santo Domingo Date: 14.iii.1978 Coll.: L. Masner ”.

Redescription. FEMALE (holotype). Body length 1750 µm. Head yellow except trabeculae and ocelli dark brown; scape and pedicel light brown, flagellum brown to dark brown; mesosoma and metasoma mostly dark yellow to light brown; legs mostly light brown except metatibia brown.

Antenna ( Fig. 370 ) with pedicel very small, much shorter than F1; F1 a little shorter than F2 and apparently without mps; F2 the longest funicle segment, apparently at least with 1 mps; F3–F8 each progressively a little shorter than preceding funicle segment, each with at least 1 but likely 2 mps; clava shorter than combined length of F5–F8.

Mesosoma ( Fig. 371 ). Pronotum entire. Pronotum, mesoscutum, and scutellum with weak reticulate sculpture; dorsellum smooth, subtrapezoidal, much wider than long; propodeum with rows of punctures extending to its anterior margin, more numerous laterally. Forewing about 3.9x as long as wide; longest marginal seta about 0.2x maximum wing width; disc bare behind venation except for several setae just behind marginal and stigmal veins and slightly, more or less uniformly infumate. Metacoxa strongly reticulate.

Petiole reticulate, about 7x as long as wide. Gaster shorter than mesosoma. Ovipositor short, not exserted beyond gastral apex.

MALE (allotype). Body length 1750 µm. Similar to female except for normal sexually dimorphic features and the following. Mesosoma a little darker than in female, distal half or so of gaster (except for the apex) brown, remainder of gaster light brown. Antenna light brown (more or less scape, pedicel, and F1–F3) to brown. Forewing with a light brown transverse band approximately half way between apex of venation and apex of wing. Petiole almost as long as gaster.

Diagnosis. Gonatocerus (Cosmocomoidea) masneri is a member of the masneri species group. It differs from G. (Cosmocomoidea) hispaniolus sp. n., the only other known species of the species group, by the completely dark funicle of the female antenna ( Fig. 370 ) and also by the relatively lighter color of the body and antenna of the male.

Distribution. NEOTROPICAL: Dominican Republic. Yoshimoto (1990) misspelled this country’s name, and De Santis & Fidalgo (1994) erroneously indicated Dominica as the country of the type locality along with the Dominican Republic.

Hosts. Unknown.

Comments. The female antenna and forewing illustrated by Yoshimoto (1990, figs 20 and 69, respectively) do not agree with either the description or the holotype of his G. masneri (e.g., F1 is short in fig. 20 and the forewing has two bands in fig. 69); his photograph of the antenna (fig. 20) is of an undescribed species collected in Ecuador, Napo, Limoncocha , 15–28.vi.1976 [CNCI] that belongs to the morrilli subgroup of the ater species group, whereas his photograph of the forewing (fig. 69) is actually that of the holotype male of G. (Cosmocomoidea) helavai Yoshimoto.
