Haplosymploce andamanica ( Princis, 1951) , new record from China

( Figs. 2–3 , 8–17 )

Mopsera andamanica Princis, 1951: 59 (Type locality: Andaman Islands). Pseudothyrsocera andamanica: Princis, 1969: 956 .

Haplosymploce andamanica: Roth, 1997: 99 .

Description. Measurements (mm). Overall length: male 17.1; pronotum length×width: male 3.1×4.0, female 3.7×4.4; tegmen length: male 14.0, female 14.0. (female data after Roth 1997)

Male. Body size medium, yellowish brown. Vertex and frons brown, apical part of clypeus and entire labrum yellowish brown. Ocellar spot large, pale. Maxillary palpi blackish brown. Antenna with basal minor part blackish brown and apical major part brownish yellow. Pronotum with punctations ( Fig. 10 ), disk brownish orange, border brownish yellow. Tegmen orangish yellow. Abdomen with 1–5 segments yellowish brown and 6–10 dark brown. Legs brown. Cerci yellowish brown.

Interocular distance on vertex distinctly shorter than that between antennal sockets. Maxillary palpus with 3rd segment as long as 4th segment, distinctly shorter than 5th segment. Pronotum rounded, widest at posterior one-third. Tegmen and hindwing fully developed, extending beyond the end of abdomen. Tegmen with radial branches pectinate of which some apical ones bifurcated, branches of M and CuA longitudinal, M bifurcate before midpoint. Hindwing with RA six-branched, M bifurcated near the apex, CuA with 5–7 complete branches and 2 incomplete branches. Front femur type B3 or B4.

T1 of male abdomen specialized ( Fig. 14 ), with a pair of fossae at the middle, of which the front margin bears sparse long hairs, between the fossae is a dense cluster of setae, a pair of filamentous membranes arising from the posterior margin of the metanotum extends to the first abdominal tergum; T7 with a setose cluster ( Fig. 15 ), of which the setae curve outward. Supra-anal plate ( Fig. 16 ) symmetrical, pentagonal; paraprocts ( Fig. 16 ) dissimilar, with curved robust sclerites, right one with some ten large apical spines (as indicated by the arrow in Fig. 16 ), left one without apical spines (3 in Roth 1997); intercercal processes ( Fig. 16 ) similar, curved downwards, each with an apical spine. Subgenital plate ( Fig. 17 ) asymmetrical, left of hind margin slightly emarginated, each side of this area bearing a stylus respectively; styli cylindrical with small spines, right larger than left. L3 ( Fig. 17 ) covered by a spicular membrane, near the hook is a setose membrane; L2vm ( Fig. 17 ) rod-like, slightly curved, apex pointed, near which is a cluster of black hairs; sclerite of the right phallomere (R3) with a branch, basal part with several spines; sclerites of the right phallomere (R2) ( Fig. 17 ) with 2–3 sclerites, irregular.

Female (after Roth 1997). Front femur type B3, supraanal plate strongly trigonal of which the hind margin much more acute than that of males.

Type specimens (not examined). Male holotype (terminalia slide 111), Port Blair, Andaman Islands, Roeppstorff; female paratype, Andaman Islands, same data as holotype. Placed in Zoological Museum, Copenhagen, Denmark ( ZMUC).

Materials examined. 1 male ( MHBU), China, Yunnan, Ruili, 2004. V.17–18, coll. Xiujuan YANG and Yushuang LIU; 1 male (KIZCAS), China, Yunnan, Puer, Ximeng, 1981. VI.21, coll. Dazhi DONG.

Remarks. Sclerite R3 of individuals from Yunnan differs from that from Andaman described by Roth (1997), the former has several small spines at the base, while the latter has no spines. However, the tergites, supra-anal plate, intercercal processes and subgenital plate of the individuals from these two areas are almost the same.

Distribution. China (Yunnan) and Andaman Islands.
