( Figs 64–70 View FIGURES 64 – 70 )

Female. Body length ( Fig. 64 View FIGURES 64 – 70 ): 2.5–2.6 mm. Body color: Head dark brown except scape and pedicel yellow; mesosoma dark brown, except legs yellow; wings hyaline; metasoma black-dark brown. Head ( Figs 65–66 View FIGURES 64 – 70 ): antenna with 22–23 flagellomeres; flagellar length/width ratios as follows: F1 = 3.6, F10 = 2.2, last flagellomere = 2.4; last flagellomere terminating apically in a sharp point; pedicel as long as wide; scape 1.6–2.2 × longer than wide; mandibles when closed overlapping for 0.5–0.6 × mandible length; mandible width basally 0.5 × mandible length; malar space 0.2 × eye height, and 0.7–0.9 × basal mandible width; gena sparsely pubescent; shortest distance between eyes equal to clypeus width; eye in lateral view 1.6–1.7 × taller than wide; lateral ocellus separated from compound eye by a distance 1.0–1.3 × ocellar width; frons glabrous; vertex with a few scattered setae; temple with few scattered setae; temple width 0.6–0.7 × eye width; occipital carina thick and complete. Mesosoma: pronotum glabrous; pronotum in lateral view mostly smooth, medially foveate; propleuron with anterior and medial margins rugose, remaining surface smooth-punctate; median mesonotal lobe anteriorly pubescent, posteriorly glabrous; lateral mesonotal lobes mostly glabrous with a single row of setae on lateral border; notauli either absent or only present anteriorly ( Fig. 68 View FIGURES 64 – 70 ); pit on mesoscutum small and oval ( Fig. 68 View FIGURES 64 – 70 ); scutellar sulcus with one carina; scutellar disc pubescent; mesopleuron centrally glabrous, borders and area below precoxal sulcus pubescent; precoxal sulcus foveate; metanotum irregularly longitudinally carinated; metapleuron pubescent; propodeum pubescent except dorsum glabrous; propodeum subdivided into anterior and posterior halves by a strong transverse carina, and either with or without a median-longitudinal dorsal carina ( Fig. 67 View FIGURES 64 – 70 ); propodeum with surfaces mostly smooth except laterally rugose. Legs: hind coxa 1.6 × longer than middle coxa; hind femora length 4.7 × maximum width; hind tibia length 11.0 × longer than maximum width; hind tibial spur 0.7 × as long as hind basitarsus; ratio of hind tarsomeres from basitarsus apically 15:7:6:4.5:10. Wings: fore wing length 2.4–2.9 mm; pterostigma 3.0 × longer than maximum width; length of marginal cell 2R1 along anterior wing margin equal to the length of pterostigma; vein r-rs 0.5 × as long as pterostigma width; vein Rs+M absent; vein mcu either basal or interstitial with vein RS; hind wing with three sickle-shaped hamuli. Metasoma: first tergite basally 0.9 × as wide as apical width, and 1.8 × longer than apical width; sculpture of first tergite longitudinally costate, except for a smooth area basally ( Fig. 69 View FIGURES 64 – 70 ); spiracle of tergum one situated on lateral margin near the basal quarter of segment; hypopygium long, ventrally convex and with dorsal margin rounded; ovipositor sheath 1.3–1.4 × as longer as basitarsus, and 2.1–2.7 × longer than basal width; ovipositor sheath pubescent; ovipositor sheath terminating in a rounded area ( Fig. 70 View FIGURES 64 – 70 ).

Male. Unknown.

Female holotype. COSTA RICA, San Jose, Cerro de la Muerte , 6 Km, N. San Gerardo, 2800 m, November 1993, P. Hanson leg., Malaise. Deposited in UWIM.

Paratypes. COSTA RICA: One female, San Jose, Zurqui de Moravia , 1600 m, vi.1992, P. Hanson leg., Malaise. One female , San Jose, Zurqui de Moravia , 1600 m, x.1995, P. Hanson leg., Malaise. All paratypes deposited in UWIM.

Comments. Centistes cabecares and C. acuticaudatus display similar morphology, especially the shape of ovipositor sheaths, but C. cabecares differs by having the vein Rs+M absent (vein Rs+M present as a short stub in C. acuticaudatus ).

Etymology. This species is named after the Cabecares , an indigenous group who reside at the Cordillera of Talamanca, the mountainous region where the holotype specimen was collected.
