Silhouettanus insuloparvus sp. n.

( Figs 5 B–D, 6A–G, dimensions in Table 1 )

Type material. Holotype: MNHN (EH)19901, mac. ♂, New Caldeonia, 22º23´S 166º56´E, Cap Ndoua site 1, 150m, QM sample 11870, 29 Nov – 21 Dec 2004, Burwell and Wright, malaise trap in rainforest, dissected on three slides and vial in MNHN (EH). Paratypes: T189826-7, mac. ♂ as for holotype, on four slides but abdomen lost, in QM; mac. ♂ as for holotype but 21 Dec – 8 Jan 2005, QM sample 12064, on pin card in QM.

Description. Brown with two pale bands on wings, that is clavus, adjacent corium and distal membrane (not apex) cream. Ratio labial segmental lengths roughly 2:2:1:3. Costal lobe wide, R+M diverging from Sc basally, subcostal cell elongate, cell R <discal cell, divergence of M from R distal to basal cell, less than half area of cell R is distal to apex of discal cell; 1V joins Cu opposite tornus; vein seta medium. T8 not produced at either end; left anophoric process broad, straight, spatulate, projecting posteriorly almost to margin of genital capsule; right anophoric process not evident in slide mount; left paramere with bulbous base and broad, elongate, weakly tapering distal lobe; right paramere with bulbous base and long, curved, tapering, apically rounded distal lobe; one conjunctival sclerite bearing large crescentic process; second conjunctival sclerite without discernible spinous process; vesica very short, apically bifid.

Notes. This is the smallest species described here. It is sympatric with S. insulomagnus at Cap Ndoua at the southern tip of Grand Terre, New Caledonia (QM site 1, NC37-016).

Etymology. Latin, alluding to the small size of this insular species; adjective.
