Tan, 2012: 13— Duolandrevus species 1

Material examined. Holotype: male (ZRC.ORT.247), Mandai secondary forest, coll. M. K. Tan & R. W. J. Ngiam, 17 March 2011. (ZRC).

Paratypes: 2 males, Singapore : 1 male (ZRC.ORT.172), Bukit Timah Nature Reserve, Belukar Track, coll. M. K. Tan & H. P. M. Woo, 31 December 2010; 1 male (ZRC.ORT.289), Bukit Timah Nature Reserve, Senapang Link, coll. M. K. Tan, 29 May 2011. 3 females, Singapore : 1 female (ZRC.ORT.14), Pulau Ubin, Sensory Trail, coll. M. K. Tan, 18 June 2010; 1 female ( ZRC. ORT.231), Central Catchment Nature Reserve , Chestnut Track, coll. M. K. Tan, 20 February 2011 ; 1 female (ZRC.ORT.442), Bukit Timah Nature Reserve, Belukar Track, 5 January 2013, coll. M. K. Tan, R. W. J. Ngiam & Y. F. Chung. (All ZRC).

Diagnosis. Posterolateral epiphallic lobe elongated and claw-like. Ventromedial projections of posterolateral epiphallic lobes pointing internally with rounded apex. Rachis long, but not surpassing ventromedial projections of posterolateral epiphallic lobes; apical part with ventral acute process, with elongated and rounded lobe at apex as in E. tomentosa .

Description. Body typical of the genus, slightly dorso-ventrally compressed and densely pubescent ( Fig. 2 View FIGURE 2 A). Frontal rostrum less wide than scapus, with apex roundly truncated. Maxillary palpi with apical (fifth) segment distinctly larger, broader and longer than third segment, about same length as fourth segment, with apex rounded. Pronotum transverse, clearly wider than long; margins with strong hairs; dorsal plate with anterior and posterior margins straight, lateral lobe longer than tall. Fore tibia with only internal tympanum. Hind tibia inner and outer margin with 5 stout articulated spurs on each dorsal side; and 3–4 much smaller basal spines. Hind tarsus with 4–5 inner and outer subapical spines.

Tegmen extending to middle of 5th abdominal tergite, overlapping with one another ( Fig. 2 View FIGURE 2 A); lateral field with 7 longitudinal veins; dorsal field distinctly longer than lateral field, with distal margin rounded ( Fig. 2 View FIGURE 2 B). Hind wings absent. Metanotal gland transverse with two shallow depressions separated by a ridge in the middle; ridge with long and strong hairs along anterior and posterior margins; posterior margin feebly concave in the middle ( Fig. 2 View FIGURE 2 C). Ninth abdominal tergite transverse. Anal plate (epiproct fused with 10th abdominal tergite) triangular, broad basally and tapers into an obtuse apex; sparsely setose basally, glabrous in the middle, densely setose in the apical third (including the distal margin) ( Fig. 2 View FIGURE 2 D). Subgenital plate longer than broad, apex truncated. Male genitalia as shown in Figs. 2 View FIGURE 2 E–2G. Epiphallus deeply and broadly notched with lobueles between; posteromedial epiphallic lobule slender and acute; ( Fig. 2 View FIGURE 2 E). Posterolateral epiphallic lobe elongated and claw-like (when viewed laterally) ( Fig. 2 View FIGURE 2 F); slightly swollen ventro-basally; slightly curved internally (when viewed dorsally) ( Fig. 2 View FIGURE 2 E); slightly curved dorsally (when viewed laterally) ( Fig. 2 View FIGURE 2 F); setose dorsally, particularly at the basal part; apex finger-like (almost acute in profile). Ventromedial projections of posterolateral epiphallic lobes pointing internally with rounded apex ( Figs. 2 View FIGURE 2 E, 2G). Rachis (or ectophallic fold long, but not surpassing ventromedial projections of posterolateral epiphallic lobes; apical part with ventral acute process, with elongated and rounded lobe at apex ( Fig. 2 View FIGURE 2 G). Formula small.

Female. Habitus as shown in Fig. 3 View FIGURE 3 A. Tegmen reaching 4th abdominal tergite ( Figs. 3 View FIGURE 3 A, 3B). Anal plate transverse and broadly rounded apically, flattened in the middle, with hairs in the apical third ( Fig. 3 View FIGURE 3 C). Subgenital plate about as long as broad; apical margin excised in the middle ( Fig. 3 View FIGURE 3 D). Ovipositor long, surpassing hind knee; with acute apex and upper valves distinctly longer than ventral valves; upper valves slightly curved ventrad apically ( Fig. 3 View FIGURE 3 E).

Colouration. Generally red brown or brown. Head red brown, antenna scapus lighter brown. Gena, maxillary palpi and clypeus pale yellow brown. Pronotum red brown. Tegmen red brown. Legs light brown. Hind femur mostly light brown, but red brown near knee; hind tibia red brown, dorsally dark brown except the basal and distal parts; hind tarsus red brown; spines on hind tibia and tarsus brown with black tips. Thoracic segments pale yellow brown. Abdominal tergites red brown and male epiproct dark brown. Abdominal sternites and male subgenital plate yellow brown.

Measurements (in mm). See Table 1 View TABLE 1 .

Etymology. The species is named after the Disney character, Jiminy cricket, from the book The Adventure of Pinocchio.
