description: Centistes hirsutus Aguirre, Almeida & Shaw, sp. n.
(Figs 113–119)
Female. Body length (Fig. 113): 2.6–2.8 mm. Body color: head dark brown except gena and antenna basally yellow, clypeus either whitish or brown; mesosoma black-dark brown except basal half of pronotum, propleura and legs yellow, though sometimes hind telotarsus dark brown; wings hyaline; metasoma dark brown except T1 black. Head (Figs 114–115): antenna with 22–23 flagellomeres; flagellar length/width ratios as follows: F1 = 3.0, F10 = 2.3, last flagellomere = 1.9; 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– 0.5 × mandible length; malar space 0.3 × eye height, and equal to basal mandible width; gena sparsely pubescent; shortest distance between eyes 1.1–1.2 × greater than clypeus width; eye in lateral view 1.6–1.7 × taller than wide; lateral ocellus separated from compound eye by a distance 1.7–1.9 × ocellar width; frons pubescent but medially glabrous; vertex pubescent; temple pubescent; temple width 0.8–0.9 × 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 surfaces smooth; median and lateral mesonotal lobes pubescent (Fig. 117); notauli either absent or only present anteriorly; pit on mesoscutum large and oval (Fig. 117); 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 irregularly longitudinally 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, sometimes carinate-areolate (Fig. 116); propodeum surfaces carinaterugose, with smooth areas on dorsum. Legs: hind coxa 1.6 × longer than middle coxa; hind femora length 4.6 × maximum width; hind tibia length 10.0 × longer than maximum width; hind tibial spur 0.4 × as long as hind basitarsus; ratio of hind tarsomeres from basitarsus apically 16:9:7:6:9. Wings: fore wing length 2.5–3.0 mm; pterostigma 3.1 × longer than maximum width; length of marginal cell 2R1 along anterior wing margin 0.9 × the length of pterostigma; vein r-rs 0.4 × as long as pterostigma width; vein Rs+M present as a short stub; vein m-cu basal with vein RS; hind wing with three sickle-shaped hamuli. Metasoma: first tergite basally 0.6 × as wide as apical width, and 1.5 × longer than apical width; sculpture of first tergite longitudinally costate with costae almost parallel (Fig. 118); spiracle of tergum one situated on lateral margin near the basal quarter of segment; hypopygium short and ventrally convex; ovipositor sheath 2.3–2.5 × longer than basal width, and as long as basitarsus; ovipositor sheath densely pubescent; ovipositor sheath terminating in a rounded (Fig. 119).
Male. Unknown.
Holotype female. COSTA RICA: Cartago Pr., La Cangreja, 1950 m, i.1992, P. Hanson leg., Malaise. Deposited in UWIM.
Paratypes. COSTA RICA: One female, San Jose, Zurqui de Moravia, 1600 m, iii.1992, P. Hanson leg., Malaise. One female, San Jose, Cerro de la Muerte, 6 km N. San Gerardo, 2800 m, xii.1992 – ii.1993, P. Hanson leg., Malaise. All paratypes deposited in UWIM.
Comments. Centistes hirsutus, C. auricephalus and C. pilosus share a conspicuous pubescence on head and thorax. However, C. hirsutus differs by having the combination of the head being completely yellow and vein Rs+M present as a short stub.
Etymology. The Latin adjective “ hirsutus ”, which means hairy, refers to this species conspicuous pubescence.
