Holotype.

♀ in USNM. COSTA RICA: ACG, Guanacaste Province, Sector Santa Rosa, Bosque San Emilio, 300m, 10.84389, -85.61384. ACG database code: DHJPAR0013328.

Paratypes.

5♀, 5♂ (BMNH, CNC, USNM, INBio, INHS). COSTA RICA, ACG, database codes: DHJPAR0012601, DHJPAR0013317, DHJPAR0013329, DHJPAR0013331, DHJPAR0013333, DHJPAR0013334, DHJPAR0013335, DHJPAR0013337, DHJPAR0024712, DHJPAR0024713.

Diagnosis.

The combination of T1 length at least 3.0 × its width at posterior margin, body mostly dark reddish brown to brown, metatibia dark brown on posterior 0.8, and metatibial spurs yellow white separates this species from all other ACG Snellenius , except for Snellenius gerardoherrerai . It is distinguishable from the latter species by having scape dark brown, tegula and humeral complex yellow, and relatively longer flagellomeres (flagellomere 2 3.0-3.2 × as long as wide, flagellomere 14 2.5-2.7 × as long as wide).

Description.

Female. Scape color: Dark brown to black. Mesosoma color: Black. Metasoma color: Dark brown. Coxae color (pro-, meso-, metacoxa): Yellow, yellow, reddish brown. Femora color (pro-, meso-, metafemur): Yellow, orange brown, dark reddish brown. Tibiae color (pro-, meso-, metatibia): Yellow, yellow, yellow white on anterior 0.4 and dark brown on posterior 0.6. Metatibia spurs color: White. First segment of metatarsus color: Dark brown. Tegula and humeral complex color: Yellow, yellow (rarely yellow, partially yellow and partially brown). Wings: Hyaline. Pterostigma color: Brown with small pale spot at base. Fore wing veins 1RS and (RS+M)a: Brown (same color as surrounding veins). Body length (head to apex of metasoma): 2.9-3.2 mm (X = 3.0 mm). Fore wing length: 2.5-2.7 mm (X = 2.6 mm). Ocular-ocellar line /posterior ocellus diameter: 1.9-2.0 x. Interocellar distance/posterior ocellus diameter: 1.7-1.8 x. Ocular-ocellar line/posterior ocellus diameter/interocellar distance: 0.14 –0.15/0.07–0.08/0.12– 0.14 mm. Antennal flagellomere 2 length/width: 3.0-3.1 × (0.24-0.25/0.08 mm). Antennal flagellomere 14 length/width: 2.2-2.7 × (0.15 –0.16/0.06– 0.07). Length of flagellomere 2/length of flagellomere 14: 1.5-1.7 x. Antenna in males: Of normal appearance, not flattened. Epicnemial carina: Present (partially visible). Anteromesoscutum: With strong, coarse sculpture, central area appearing elevated compared to lateral areas of anteromesoscutum, notauli wide and deeply excavated, with numerous crenulae. Scutellar disc sculpture: With deeper sculpture near margins, central part appearing slightly elevated and less sculptured. Number of carinae in scutoscutellar sulcus: One complete and up to four incomplete. Metafemur length/width: 3.6-3.8 × (0.80/0.21-0.22 mm). Metatibia length: 1.05-1.08 mm. First segment of metatarsus length: 0.38-0.40 mm. Mediotergite 1 length/width at posterior margin: 2.5-2.7 x. Mediotergite 1 length/width at anterior margin/maximum width/width at posterior margin: 0.43 –0.46/0.20/0.19– 0.20/0.17 mm. Mediotergite 1 sculpture: Fully sculptured.

Male. As in female but with lighter coloration on metafemur.
