NOTE

Based on article 30.1.4.3 of the ICZN, a genus-group name ending in -ops is to be treated as masculine and it is thus necessary to replace P. spinulosa with P. spinulosus .

REDESCRIPTION MALE

Colouration: General colouration brown. Head brown with frons blackish and ocelli black. Fore coxae brown with irregularly dotted ivory spots on internal surface. Internal surface of fore femora with two black bands. Tegminae variegated brown. Metathoracic wings hyaline and smoked with apex opaque and brown. Tergites ochraceous with apical shiny black band; sternites, mid and posterior legs blackish.

Head (Figs 7, 64-66): About 1.63 times as wide as a pronotal supracoxal dilatation; process of vertex squarish not well developed with two small spines in the apex; eyes oblong with a big ocular apical spine (approximately 1.5 as long as diameter of one ocellus). Frontal ridge behind the upper ocelli rises to form a small triangular process. Occiput with one conical process on both besides. Frontal shield transverse, about twice as broad as high, pentagonal with bidentate apex (Fig. 7).

Thorax: Pronotum (Figs 67-72) 3.13 times as long as its maximum width; it is narrowed in the distal half of metazone; lateral margins weakly subdentate; disc with some sparse granules, two flattened processes are present near posterior margin; pronotal supracoxal dilatation distinct and with rounded lateral margins. Fore coxae about 0.74 times as long as pronotum; lateral margins with small granules; internal surface with ivory calluses; posterior surface with sparse small tubercles; internal distal lobes contiguous. Fore femora (Fig.18) 0.95 times as long as pronotum length and 4.59 times as long as its maximum width; upper margin with numerous small granules,

Pseudacanthops spinulosus (male): (64-66) Head, 64 from Suriname, 65 from Venezuela, 66 from French Guyana. (67-72) Pronotum, 67 & 70 from Suriname, 68 & 71 from French Guyana, 69 & 72 from Venezuela. Scale = 0.5 cm.

basal lobe distinct with regular free margin; external surface with 5-6 small tubercles on the median line. Tibiae half the length of the femora. Formula spination F=6ES/14IS/4DS and T=18-21ES/16-17IS. Middle and hind legs covered with long hairs. Femora with 2-3 tubercles on external surface and with a rounded basal lobe on the medial external margin. Tibiae (Fig. 22) basal half thicker than distal half and with a medial lobated swelling; apex with a small lobe. Metatarsi length less than the total length of all the other segments together. Wings well developed, extending well beyond the tip of abdomen. Mesothoracic wing (Figs 74-75) ratio total length/- maximum width 4; costal area opaque not well dilated at base with an attenuate excavation; discoidal field opaque in its anterior half and at the apex, hyaline in its posterior half. Metathoracic wing with costal area subopaque and discoidal area hyaline.

Abdomen (Fig. 73): Cylindrical, slightly flattened, lateral margins of urotergites 5th and 6th with a leafy dentate lobe. Lobes of 2nd, 3rd, 4th and 7th similar to previous but smaller. 8th and 9th with a slender lobe. Urosternites with a longitudinal median carina bilaterally flanked by two or three shorts crests near the distal margin. Subgenital plate longer than broad with incised apex, styli small. Supranal plate short,

deeply incised at apex. Cerci extend beyond the subgenital plate with long hairs, last segment (Figs 76-77) very large, flattened, lateral margins sinuous and incised at apex, forming unequal terminal lobes.

Male external genitalia: Ventral phallomere (Figs 83-85) 2.5 times as long as its width, distal process elongate ending in an acuminate apex; lateral process elongate with dentate lateral margin. Left phallomere (Figs 78-82) well sclerotized; ventral lamina with distal process dilated; anterior process elongate and with small teeth on upper margin.

Measurements (millimeters): Head width 5.5-5.9; pronotum supracoxal dilatation width 3.4-3.6; prozone length 3.4-3.7; metazone length 6.8-7.6; fore coxae length 7.8-8.5; fore femora length 10.1-10.6; tegminae length 38-40.

FEMALE

Head about 1.53 times as wide as supracoxal pronotal dilatation, with numerous, various in size, tubercles. Pronotum more robust of male, narrower at centre of metazone with numerous tubercles more or less developed on the disc; lateral margins of metazone dentate. Posterior margin with two big processes. Legs more robust of the male and more tuberculated; Wings not well developed and opaque. Mesothoracic wing with a long narrow apical lobe originating about its half way. FIGS 78-85

External copulatory of Pseudacanthops spinulosus : (78-82) Left phallomere, 78 & 81 from French Guyana (in ventral and dorsal view), 79 & 82 from Venezuela (in ventral and dorsal view), 80 from Suriname (in ventral view). (83-85) Ventral phallomere, 83 from French Guyana, 84 from Suriname, 85 from Venezuela. Scale = 1 mm.

Anterior margin sinuous; posterior margin crenulated. Metathoracic wing opaque with chestnut concentric spots.

Abdomen similar to those described in the male but lateral lobes more developed.

DISTRIBUTION: This species occurs from Venezuela to French Guyana (Fig. 96).
