Panjange lanthana Deeleman-Reinhold & Deeleman, 1983: 124 , Fgs 1–9 (Ƌ ♀).

Panjange lanthana – Huber 2011: 111–114, Fgs 436–58, 765–66, 786, 788 (Ƌ ♀).

Note

Previously, the type species Pa. lanthana was both geographically and systematically isolated. It was the only known Philippine representative of the genus and single representative of the lanthana “group” (Deeleman- Reinhold & Platnick 1986; Huber 2011), as it did clearly not Ft into any of the other two species groups.

With the new species from the Philippines described below, the lanthana group can Fnally be characterized based on several species, and the emended diagnosis below takes account of these new species.

Diagnosis

Distinguished from closest known relatives (other species of lanthana group) by absence of processes arising from near male PME (cf. Fg. 441 in Huber 2011), by presence of clearly visible AME, and by morphology of male palp (cf. Fgs 436, 437 in Huber 2011; procursus with two highly distinctive sclerites hinged against proximal part; appendix with simple weakly sclerotized tip). From three species of the lanthana group ( Pa. malagos Huber sp. nov.; Pa. casaroro Huber sp. nov.; Pa. camiguin Huber sp. nov.) also by symmetric palps; from another three species of the lanthana group ( Pa. isarog Huber sp. nov.; Pa. dinagat Huber sp. nov.; Pa. marilog Huber sp. nov.) also by unmodiFed male clypeus and by epigynal scape directed toward posterior (Fg. 439 in Huber 2011); from Pa. hamiguitan Huber sp. nov. also by much shorter palpal segments and epigynal scape.

New material examined

PHILIPPINES: Luzon, Camarines Sur Province: 2 ƋƋ, 4 ♀♀ in ZFMK ( Ar12997 ) and 1 Ƌ, 1 ♀ in MSU-IIT, Mt. Isarog , W slope (13.664°N, 123.34– 123.35°E), ~ 600–900 m a.s.l., forest , on leaves , 23 Feb. 2014 (B.A. Huber) ; 6 juvs in pure ethanol in ZFMK ( Phi 224 ), same data .

Natural history

All specimens were found in a shady ravine, with their domed webs connected to the undersides of green leaves among the vegetation, about 1–2 m above the ground.

Distribution

Known from two localities on southern Luzon Island ( Fig. 16 ).
