Telogmometopius himalayensis sp. nov.

( Figures 35 , 80–82 )

Description

Length: „ 5.4–5.5 mm, ♀ 5.6 mm.

Vertex and pronotum ochraceous, callous areas on posterior area of vertex and anterior area of pronotum brown; scutellum ochraceous, central foveate area and two callous areas on lateral basal angles brown. Head ventrally brown, postclypeus with median keel and the areas between lateral striate fasciae on lateral compressed areas ochraceous. Thorax ventrally brown, fore- and mesosterna, metapleura, and metasterna ochraceous. Legs brown, fore femora with extreme base ochraceous; posterior tibiae (excluding base) and tarsi of hind legs ochraceous; rostrum ochraceous. Fore wings grey brown, apical area and costal marginal area after middle fuscous. Abdomen brown with posterior segmental margin, pygofer and genitalic segment ochraceous.

Postclypeus with median keel very sharp.

Male genitalia similar to T. carinilabratus but aedeagus ( Figure 81 ) slightly more robust with apical filamentous process sinuate rather than coiled.

Material examined

Holotype: „, [ India]: east Himalayas , Kurseong , alt. 5000 ft, 10–26 September [19]09 (Lynch, c., Ind. Mus.) ( BMNH). Paratypes: [ India]: 1 „, same data as holotype; 1♀, same data as holotype except 7 September [19]09 (N. A., Ind. Mus.) (both in BMNH).

Non-type material examined. The following specimens may belong to this species. China, Tibet: 3 „„, 3♀♀ (1♀ collected at light), Mêdog , 1310 m, 13, 23, and 28 September 1979 (G.- T. Jin and J.-Y. Wu) ( SIE; IZCAS); 2♀♀, Mêdog, Gelin, 1550–1900 m, 24 May 1983 (Z. Lin) ( IZCAS) .

Distribution

Northeastern India (east Himalayas), southwestern China (Tibet).

Remarks

This species is very similar externally to T. carinilabratus but can be distinguished by its smaller size and small differences of the aedeagus as noted in its description. A series of specimens from China, Tibet (SIE; IZCAS), may be this species but individuals are slightly larger.

Telogmometopius obsoletus Jacobi

Description

Length: „ 5.4–5.6 mm, ♀ 5.6–5.8 mm.

Vertex, pronotum, and scutellum ( Figure 36 ) pale ochraceous; ocelli with red or brown suffusion; callous areas on vertex and pronotum, posterior area of pronotum and central foveate area of scutellum usually with brown suffusion; antennal sockets, basal antennal segments and anterior margin of frons in ventral view brown, forming a distinct, transverse, brown fascia in ventral view; rostrum ochraceous; thorax ventrally ochraceous, mesosterna brown; fore and middle legs brown, extreme base of fore and middle femora ochraceous, hind legs ochraceous; fore wings grey brown, sparkled with ochraceous, with an indistinct, narrow, obliquely transverse, pale white fascia before middle; abdomen brown, posterior segmental margin and genitalic segment ochraceous.

Postclypeus with medial keel moderately sharp.

Male genitalia with subgenital plates ( Figures 14–16 , 98–100 ) closely approximated, with expanded basal region moderately long and oval-shaped; apical spine-like process short and fine, distinctly shorter than expanded basal region. Style as in Figure 102 . Aedeagal shaft ( Figure 103 ) relatively short and broad in lateral view, compressed laterally, distal two-thirds evenly broad in lateral view; with an anterodorsally directed, membranous, sinuate filamentous process arising subapically from upper margin.

Type material examined

Lectotype: ♀, here designated, China: ‘‘[yellow label] China; [yellow label] 1916/2; [red label] Typus; coll. A. JACOBI; [Jacobi’s handwriting] Telogmometopius obsoletus JAC. det. A. Jacobi; [red label] LECTOTYPE ♀ Telogmometopius obsoletus Jac. desig. A.P. Liang 1990’’ ( SMTD) .

Other material examined. China, Hubei: 4 „„, Xingshan, Longmenhe , 1300 m, 9 September 1994 (J. Yao); 1 „, same data and altitude, but collected at light, 8 September 1994 (J. Chen) (all in IZCAS, BMNH) . China, Gansu: 3 „„, Kang County, Qinghe forest, 1400 m, 8 July 1999 (J. Yao); 1 „, same data but collected by T.-L. He (all in IZCAS, BMNH). China, Sichuan: 1 „, Mt Emei , Jiulaodong, 1800–1900 m, 23 August 1957 (Z.-Y. Wang) ( IZCAS) . China, Guizhou: 1♀, Guiyang, Qianlingshan , 1500 m, 10 June 1981 (F.-S. Li) ( CAUIC) .

Distribution

Southern and central China (Hubei, Gansu, Sichuan, Guizhou,? Jiangxi). Remarks

This species is similar to sabahensis but can be distinguished by the subgenital plates with the apical spine-like process shorter and finer and the aedeagal shaft slightly more robust in lateral view. We have not been able to verify the distribution of the species from Jiangxi [Kiangsi], China ( Wu 1935; Metcalf 1961).
