Examnes kawakamii Yokoi, Makihara & Noerdjito

Figs 15A-D , 26A-F

Examnes kawakamii Yokoi et al., 2016: 233. Type locality: Bukit Soeharto, Kalimantan Timur, Indonesia.

Examined specimen.

1♂: "Basilan Philippin"; “Coll-Schwarzer”; "Senckenberg-Museum, Frankfurt". (SMF).

Supplementary description of male genitalia

(Figs 15C, D , 26A-F ). Median lobe and tegmen as of the holotype. Apical process of endophallus as Figs 15C, D , 26C-E ; about 1/4 as long as median lobe, sub-monolithic; the middle thick and stout, with a prominent, horn-shaped dorsal projection; sides apically projected, each loosely connected to an extra-large, bi-lobed, membranous apical appendage; adjacent membrane of endophallus longitudinally perforated with thick edges; base sub-squarish-spatulate. Blade of 8th sternite in shallow “V” -form emarginated.

Remark.

Endophallus of this species is described above, as it was not included in the previous description of the holotype from Borneo ( Yokoi et al. 2016).

Distribution.

Borneo; Basilan, Philippines (New Record).

Comparative notes.

No essential difference from the holotype from Borneo is observed. Though the apex of 8th sternite is less strongly emarginated, the deviation is tolerable as a variation within a species. Apical process of its endophallus is essentially of similar structure as that of E. philippensis . Differences are concerned with the structures of sides and base as well as of appendage (Figs 26C-E , 27D-F ). The disproportionately large appendage is remarkable.
