Name

Psyttoma latilabris (Chen & Weng, 2005) comb. n.Wikispecies linkPensoft Profile

  • Opius latilabris Chen & Weng, 2005: 110 (Chinese key), 112–113 (description in Chinese; fig. 47), 180 (English key), 199 (description in English) (examined).

Type material

Holotype (Beneficial Insects Laboratory, Fujian Agriculture and Forestry University, Fuzhou), ♀, “[China:], Hubei, Shennongjia, Honghua, 2.vi.1988, Zhang Li-qin”. Paratype: 1 ♂, “[China:], Hubei, Shennongjia, Yangriwan, 20.vi.1988, Yang Jian-quan”. The holotype has the head missing and the wing venation is bleached.

Additional material

1 ♀ (RMNH), “N. China: Shandong, Anqiu, Suotou Mt., 31.vii.2009, c. 120 m, Li Xi-Ying, RMNH’09”, “CVA4245, sp. 11”; 1 ♂ (RMNH), same label data.

Diagnosis

Clypeus narrow, 5 times as wide as high and 0.7 times as wide as face and face distinctly transverse (Fig. 6); pronope rather large and round; medio-posterior depression of mesoscutum medium-sized and round (Fig. 5); precoxal sulcus slightly impressed and smooth; scutellum rugulose medio-posteriorly; body completely brownish-yellow (Fig. 1).

Description

Described from ♀ collected in Anqiu, length of body 2.0 mm, of fore wing 2.1 mm.
Head. Antenna with 25 segments and 1.2 times as long as fore wing; third segment 1.1 times as long as fourth segment, length of third, fourth and penultimate segments 3.5, 3.2 and 2.7 times their width, respectively; length of maxillary palp 0.9 times height of head; labial palp segments slender; labrum slanted backwards, leaving a large space below clypeus (Fig. 9); occipital carina widely removed from hypostomal carina and dorsally absent; hypostomal carina narrow; length of eye in dorsal view 2.1 times temple; frons slightly depressed behind antennal sockets, medially convex and glabrous, smooth; face smooth, medially weakly elevated; width of clypeus 5.0 times its maximum height and 0.7 times width of face; clypeus weakly convex, distinctly protruding forwards, punctate and its ventral margin thick and slightly concave; hypoclypeal depression wide and deep (Figs 6, 9); malar suture present; without punctures between malar suture and clypeus; mandible somewhat constricted medially and gradually widened baso-ventrally, with narrow ventral carina (Fig. 9), second tooth minute.
Mesosoma. Length of mesosoma 1.2 times its height; dorsal pronope large, round and pronotum oblique anteriorly (Fig. 8); pronotal sides smooth but oblique groove crenulate and posterior groove largely absent; epicnemial area smooth dorsally; precoxal sulcus medially superficially impressed, smooth as rest of mesopleuron; pleural sulcus smooth; mesosternal sulcus deep and narrow and very finely crenulate; notauli absent on disk, only anteriorly with pair of short smooth impressions; mesoscutum glabrous and strongly shiny; medio-posterior depression of mesoscutum medium-sized, deep, round; scutellar sulcus narrow and finely crenulate laterally, widened medially; scutellum convex medially, depressed and rugulose medio-posteriorly; surface of propodeum smooth, except for superficial rugulae posteriorly (Fig. 4).
Wings. Fore wing: pterostigma elongate triangular (Fig. 2); 1-R1 ending before wing apex and 1.4 times as long as pterostigma (Fig. 2); r:3-SR:SR1 = 3:27:55; 2-SR:3-SR:r-m = 15:27:7; r slender; 1-M slightly curved and SR1 straight; m-cu postfurcal; cu-a postfurcal and 1-CU1 widened; first subdiscal cell closed, CU1b short; apical third of M+CU1 sclerotized. Hind wing: M+CU:1-M:1r-m = 15:17:6; cu-a straight; m-cu present as faintly pigmented trace.
Legs. Length of femur, tibia and basitarsus of hind leg 2.3, 7.0 and 4.3 times as long as wide, respectively (Fig. 11); hind femur and tibia with medium-sized setae.
Metasoma. Length of first tergite equal to its apical width, its surface evenly moderately convex and rather densely longitudinally rugulose and dorsal carinae developed in basal 0.4 of tergite, straight (Fig. 4); second suture absent; second and following tergites smooth; length of setose part of ovipositor sheath 0.29 times fore wing, 2.7 times first tergite and equal to length of hind tibia; hypopygium distinctly acute apically and about 0.3 times as long as metasoma.
Colour. Brownish-yellow; antenna (but scapus yellowish), stemmaticum, ovipositor sheath, pterostigma and veins dark brown; palpi, mandible, tegulae and legs (but telotarsi darkened) pale yellow; wing membrane subhyaline.
Variation. Male from Anqiu has length of fore wing 2.0 mm, antenna with 24 segments, hind femur 3.0 times as long as wide and medio-anterior veins of hind wing strongly widened (Fig. 13).
Molecular data. 16S and 28S (CVA4245); GenBank Accession numbers JQ736254 and JQ736282, respectively.

Distribution

China (Shandong, Hubei).

Biology

Unknown.

Notes

In the key by Chen and Weng (2005)[1] to the Opiinae of China the type species runs to Phaedrotoma louiseae (Weng & Chen, 2005) comb. n., but this species has the propodeum with a pentagonal areola, the mesosoma brown, the first tergite 2.3 times longer than its apical width, the hind femur 6.0 times longer than wide, the antenna 1.6 times longer than body and the clypeus 1.7 times wider than high. Only by examining all Opiinae types in Beneficial Insects Lab., Fujian Agriculture and Forestry University(Fuzhou) it was found by the second author that the headless holotype of Opius latilabrisChen & Weng, 2005, from Hubei (Oriental China) is conspecific with the specimens from the Palaearctic Anqiu.
In the key by Tobias (1998)[2] to the East Palaearctic Opiinae it runs to Opius wachsmanni Szépligeti, 1898, described from Hungary (holotype examined by the second author). This species belongs to the same genus and can be separated as follows:


The specimens reported as Opius wachsmanni Szépligeti from the East Palaearctic region (Central Asia up to Korea) by Papp (1981)[3], Tobias and Jakimavicius (1986)[4] and Tobias (1998)[2] need to be re-examined and most likely belong to Psyttoma latilabris (Chen & Weng, 2005).
