( Figs 183–189 View FIGURES 183 – 189 )

Female. Body length ( Fig. 183 View FIGURES 183 – 189 ): 3.1 mm. Body color: head black except genae, clypeus and face yellow, and antennae brown; mesosoma black except legs yellow; wings hyaline; metasoma dark brown except T1 black. Head ( Figs 184–185 View FIGURES 183 – 189 ): antenna with 23 flagellomeres; flagellar length/width ratios as follows: F1 = 3.3, F10 = 3.0, F23 = 3.0; last flagellomere terminating apically in a sharp point; pedicel as long as wide; scape 1.8 × longer than wide; mandibles when closed overlapping for 0.5 × mandible length; mandible width basally 0.4 × mandible length; malar space 0.5 × eye height, and 2.0 × basal mandible width; gena sparsely pubescent; shortest distance between eyes 1.2 × greater than clypeus width; eye in lateral view 1.8 × taller than wide; lateral ocellus separated from compound eye by a distance 1.7 × ocellar width; frons glabrous; vertex with a few scattered setae; temple with few scattered setae; temple width equal to eye width; occipital carina thick and complete. Mesosoma: pronotum glabrous; pronotum in lateral view mostly smooth, medially carinate; propleuron with anterior and medial margins rugose, remaining surface smooth; median mesonotal lobe anteriorly pubescent, posteriorly glabrous; lateral mesonotal lobe glabrous except lateral borders pubescent; notauli either absent or only present anteriorly ( Fig. 187 View FIGURES 183 – 189 ); pit on mesoscutum absent ( Fig. 187 View FIGURES 183 – 189 ); scutellar sulcus bifoveate with weaker carinae inside each fovea; scutellar disc sparsely pubescent; mesopleuron centrally glabrous, borders and area below precoxal sulcus pubescent; precoxal sulcus foveate; metanotum carinated; metapleuron pubescent; propodeum pubescent except dorsum glabrous; propodeum subdivided into anterior and posterior halves by a strong transverse carina, and with a median-longitudinal dorsal carina present ( Fig. 186 View FIGURES 183 – 189 ); propodeum dorsally and posteriorly with smooth surfaces that become rugulose around the carinae, and laterally rugose. Legs: hind coxa 1.3 × longer than middle coxa; hind femora length 5.4 × maximum width; hind tibia length 11.5 × longer than maximum width; hind tibial spur 0.4 × as long as hind basitarsus; ratio of hind tarsomeres from basitarsus apically 20:10:8:6:12. Wings: fore wing length 2.8 mm; pterostigma 4.3 × longer than maximum width; vein r-rs 0.6 × as long as pterostigma width; vein Rs+M absent; vein m-cu interstitial with vein RS; hind wing with three sickle-shaped hamuli. Metasoma: first tergite basally 0.5 × as wide as apical width, and 1.5 × longer than apical width; sculpture of first tergite costate-rugulose, costae irregular ( Fig. 188 View FIGURES 183 – 189 ); spiracle of tergum one situated on lateral margin near the half of segment; hypopygium short, ventrally folded, and dorsal-posterior margin rounded; ovipositor sheath 3.2 × longer than basal width, and 0.9 × as long as basitarsus; ovipositor sheath pubescent, and terminating in a sharp point ( Fig. 189 View FIGURES 183 – 189 ).

Male. Unknown.

Holotype female. COSTA RICA, San Jose, Zurqui de Moravia , 1600 m, xi.1995, P. Hanson leg., Malaise. Deposited in UWIM.

Paratypes. Known only from holotype female.

Comments. Centistes zurquiensis and C. janzeni look quite similar, but the yellow face and glabrous (or almost so) median mesonotal lobe of C. zurquiensis make this species distinctive ( Fig. 187 View FIGURES 183 – 189 ).

Etymology. This species is named after the type locality Zurqui de Moravia.
