Neotibilis (Neotibilis) claviformis sp. nov.

( Figs. 1, 2 , 7-11 )

Type locality: Brazil, Amazonas, reserve 60 kmfrom Manaus

Type material. Holotype male, labeled: Bert Klein, 4/ XII/85, R.1301, R.C.N.2 ( INPA). Paratype male, labeled: Bert Klein, Res. 1301, R.C. S. 2, 18/XII/85 ( MCNZ) ; paratype male, labeled: Bert Klein, 13/XI/85, 1301 – R.C.N.2 ( DZRS)

Etymology. The name refers to the peculiar shape of X segment, in the pygophore.

General shape ovate. Dorsal surface dark castaneous. Jugae only sligthly deflected dorsally. Antennae yellowish castaneous, punctures visible on first segment, less visible on second, and absent on remaining segments, which are pilose. Rostrum reaching mesocoxae. Pronotum coarsely punctured; anterolateral margins yellowish castaneous. Scutellum: basal angleswith 1+1 yellowishgray to yellowish castaneous calli on basal angles; apex flat. Legs yellowish castaneous, with dark castaneous punctures on femora. Ventral surface of thorax regularly punctured on dark castaneous. Metasternal carina with a slight longitudinal sulcus. Abdominal venter yellowish castaneous; abdominal tubercle acute. Connexivum with a yellowish rounded spot over mesial third of each segment, along outer lateral margin.

Male. Measurements (n = 3). Total length 11.96 (11.35- 12.35); head length 1.77 (1.74-1.80); head width 2.50 (2.47- 2.52); eye width 0.81 (0.77-0.82); interocular distance 0.88 (0.85-0.95); anteocular length 0.56 (0.53-0.58); length of antennal segments I- 0.91 (0.85-1.00), II- 1.12 (1.04-1,17), III- 1.78 (1.42-1.99); IV- 2.71 (2.58-2.85), V -2.60 (2.50- 2.66); pronotum length 2.60 (2.53-2.65); pronotum width 6.50 (6.48-6.56); scutellum length 4.95 (4.68-5.10); scutellum width 3.82 (3.70-3.90); abdominal width 6.77 (6.72-6.96).

Pygophore ( Figs. 1, 2 ) trapezoidal, widely open dorsally; dorsal rim sinuous, openly V-shaped along proctiger ( Fig. 1 ). Proctiger elongated, clavate, rounded apically and strongly narrowed on basal half. Parameres ( Figs. 7, 8 ) with fingerlike portion little separated from the auriculate portion, partially superposed over proctiger; apex of both portions convergent. Posterolateralangles rounded. Ventral rim openly U-shaped, leaving visible the laminar flaps of ventral rim and the proctiger, ventrally ( Fig. 2 ). Laminar flaps in 1+1 tooth like projections, apices convergent to each other. Ventral inner processes of ventral rim hidden by the proctiger, not visible dorsally. Phalloteca ( Figs. 9-11 ) globose, strongly sclerotized, without processes, apical margin rectilinear. Processus vesicae 1 arising close to the base of vesica, broad basally, distal third narrow; ductus seminis distalis truncate at apex. Processus vesicae 2 sclerotized, with two apical processes divided by a shallow sulcus; 1 + 1 sclerotized tubercles, above processus vesicae 1.

Female unknown.

Comments. N. (N.) claviformis sp. nov. can be distinguished from all the remaining species by the characters of pygophore, especially by the peculiar shape of proctiger and by the acute and convergent laminar flaps of ventral rim of pygophore. The phallotheca without processes is characteristic of Laeviscutis , whereas the processus vesicae 1 arising close to the base of vesica is found in the subgenus Neotibilis . However, the strongly sclerotized processus vesicae 2 is an unique character among species of the genus.
