Wood MT / beside stream”; “ CNC/ 1866677 ”; “HOLOTYPE/ Roederiodes / woodi Sinclair [red label]” (CNC). PARATYPES: COSTA RICA. Same data as holotype (3 ♀, CNC); same locality as holotype, 26.ii.1991, nr waterfall, B.J. Sinclair, CNC103482 (1 ♁, barcoded, CNC); same data except, 23–27.ii.1991 (3 ♁, 1 ♀, CNC); same data except, CNC103483 (1 ♀, barcoded, CNC).
Recognition. This species is similar in colour to the other Central American species and can be distinguished by the clasping cercus truncate anteriorly, not projecting.
Description. Wing length 2.4–2.6 mm. Male. Face and gena without bluish pubescence. Ocellar setae divergent, subequal in length to pprn; vertical seta subequal in length to ocellar seta. Antenna with short stylus, slightly longer than postpedicel; postpedicel ovate, shortly prolonged apically. Length of proboscis slightly shorter than head height.
Pleura pale brown without bluish pruinescence; prescutellar depression without pruinescence, postalar ridge paler than scutum; several acr, very short, anterior to second pair of dc; 5 dc, long, prescutellar dc longest; 1 pprn; 1 presut spal; 2 npl; 0 psut spal; 1 pal; 2 sctl, longer than prescutellar dc and numerous setulae on disc and margin, outer marginal setulae one-third length of apical seta; laterotergite with several setae; antepronotum with several setulae; lower proepisternum with pale setae.
Wing infuscate; cell dm pointed apically, with base of M 1 and M 2 coalesced basally for short to long distance, shorter than length of crossvein r-m, or M 1 and M 2 separated by short crossvein, shorter than crossvein r-m.
Legs brown, with coxae pale brown, concolourous with pleura; coxae without bluish pruinescence. Hind tibia with weak ventral setae.
Abdominal tergites brown, darker than pleura, without bluish pruinescence; bearing short pale setae. Terminalia (Fig. 30): Hypandrium longer than length of epandrium, apex rounded; without setae. Phallus straight, with membranous distiphallus (lateral extensions not fully inflated in preparation). Cercal plate with several long setae; clasping cercus quadrate, shorter than height of epandrium, posterior margin somewhat projecting, anterior dorsal corner truncate, not projecting; thickened setae along inner dorsal margin and upper third of inner face; longer, finer outer setae, arching over posterior margin.
Female. Similar to male.
Etymology. This species is named in memory of Monty Wood, former curator of the Canadian National Collection of Insects. Monty privately purchased and built the field station, Estación Biológica Monteverde, in Costa Rica, where many of the specimens in this study were collected.
Distribution. This species is currently known only from the type locality at Estación Biológica Monteverde (Fig. 31).
