Pleurotroppopsis hirta ( Kamijo, 1977)

( Fig. 6 )

Cotterellia hirta Kamijo, 1977: 260–261 . Holotype ♀, HUMJ (examined).

Pleurotroppopsis hirta ( Kamijo, 1977) , Bouček, 1988: 711.

Diagnosis. FEMALE. Antenna entirely bluish black. Fore wing broadly infuscate below MV, with speculum reduced ( Fig. 6b ). Upper margin of scrobes slightly incised medially and frontal carina broadly sinuate medially ( Figs 6a, 6c ). Ocelli in a right-angled triangle. Mesoscutum with numerous setae evenly distributed over entire surface, including notaular depressions; MLM without a median groove or a trace of median groove ( Figs 6d, 6e ). Axilla tuberculate with numerous setae ( Figs 6d, 6e ). Scutellum with sublateral and posterior grooves ( Figs 6d, 6e ). Dorsellum smooth. Propodeum with plicae angled inwards in the middle, and with a transverse, weak carina running from the angulation to median carina ( Fig. 6e ). Gt 1 smooth with 2 irregular rows of setae posteriorly ( Fig. 6d ). Metafemur with teeth along ventral margin.

MALE. Unknown.

Material examined. Type material. Holotype ♀, Utonai, near Tomakomai , Hokkaido, ex. Tischeria sp. , em. 1.VI.1970, T. Kumata ( HUMJ); paratype ♀, same data as holotype ( HUMJ).

Biology. The type specimens of P. hirta were reared from Tischeria sp. ( Lepidoptera : Lyonetiidae ) attacking Sanguisorba tenuifolia Fisch. (Rosaceae) .

Distribution. China: Hainan ( Bouček 1988); Japan ( Kamijo 1977).

Remarks. Besides the features given in the key, P. hirta differs from P. tischeriae in the following characters: Gt 1 with 2 irregular rows of setae near the posterior margin (one row in P. tischeriae ); frontovertex with only a trace of a median groove (distinct in P. tischeriae ); dorsellum with posterior margin more weakly carinate; propodeum more weakly reticulate in posterior part of submedian areas. Its setose mesoscutum indicates a close relationship between P. hirta and P. tischeriae , as suggested by Bouček’s (1988) species group assignment. Our phylogenetic analysis supports the species group because P. hirta and P. tischeriae differ in only one character in the matrix of morphological characters ( Table 2 ). However, contrary to the discussion of Bouček (1988), the phylogenetic analysis ( Fig. 19 ) does not support the remaining known species of Pleurotroppopsis forming a monophyletic species group. Among the species, P. dentata clusters with P. hirta and P. tischeriae in the tree generated by parsimony analysis, though because of few autapomorphies ( Fig. 19 , Tables 2 , 3 ) it is still uncertain whether they are closely related. Pleurotroppopsis dentata is easily distinguished from P. hirta and P. tischeriae by the characters given in the key to species.

Unambiguous apomorphies are mapped on branches using WinClada, with black circles representing nonhomplasious changes (synapomorphies or autapomorphies), and white circles representing homplasious changes. The mirror cladogram of the strict consensus tree with 89 steps obtained from parsimony analyses in TNT is shown on the right, with numbers above the nodes indicating bootstrap values.
