Description

Body length (from apex of cephalic process to tip of forewings): ♂ 14.4 mm, ♀ 17.0 mm; length of head (including two portions: the former is from apex of cephalic process to curved point, the latter is from curved point to posterior margin of eyes): ♂ (1.0 + 1.0) mm, ♀ (1.1 + 1.2) mm; width of head (including eyes): ♂ 1.8 mm, ♀ 1.8 mm; length of forewings: ♂ 11.8 mm, ♀ 14.2 mm.

General colour greenish ochraceous, apical part of cephalic process, a longitudinal spot before eyes on genae, a small anterior spot on lower lateral carina behind eyes on pronotum, apex of hind femora and base of hind tibiae black and shining.

Cephalic process in front of eyes strongly upturned (ascending at about 45 ◦), as long as length from curved point to posterior margin of eyes in lateral view ( Figure 1B,H ). Forewings and hindwings as Figure 1A . Hind tarsomeres I with 18 and tarsomeres II with 16 apical spines, respectively.

Male genitalia. Pygofer large and broad, ventrally distinctly wider than dorsally (about 3.9: 1); posterior margin with two obtuse processes near middle in lateral view ( Figure 4E ), upper process slightly smaller than lower one. Segment X (anal tube) distinctly large and broad, with ratio of the longest length to width near base about 1.6: 1 in dorsal view ( Figure 4G ); apical ventral margins protruded ventrally into a large rounded process in lateral view ( Figure 4E ). Gonostyles relatively small, apical part elongate and rounded in lateral view ( Figure 4E,F ); upper process short, acute apically. Aedeagus large and robust, bases of dorsal and lateral parts and most of ventral part on phallobase sclerotized and pigmented, the remainder membranous; dorsal part without lobe in dorsal view ( Figure 4H ); lateral apical parts produced in a pair of long lobes, directed posteriorly in lateral view ( Figure 4I ); ventral part with two pairs of lobes: the inner two very small, directed posteriorly, the outer two distinctly large and elongate, directed posteriorly in ventral view ( Figure 4J ).

Type material examined

Holotype ♀ ( NHRS-GULI 000002777 ), Cambodia, Stevens , [red label] Typus ( NHRS).

Other material examined

1♂, LAOS: Sedone Province , Pakse, 31 May 1967, native collector ( BPBM) .

Remarks

Metaurus reticulatus was described from Cambodia based on a single female specimen, and was redescribed and illustrated in detail by Melichar (1912). Based on comparison with type specimen and our critical review of the literature, we definitely treat a male specimen from southern Laos as M. reticulatus .

Distribution

Cambodia; Laos.
