Otostigmus completus Chamberlin, 1920

(gures 48–53) Otostigmus completus Chamberlin, 1920: 15 . Otostigmus (O.) astenus (Kohlr.) : Attems, 1930: 143, gure 174.

Material examined

Holotype labelled Otostigmus completus Ch. TC-636 (2109) Solomon Is. Auki. Mann.

Description

(Chamberlin’s data in parentheses where appropriate). The specimen is well preserved but curved ventrally rendering some characters of the sternites diYcult to observe. Colour brown with blue-black sub-cuticular pigment (gure 50) (general colour olive...). (Length 50 mm.) Head nely punctate. Antennomeres 201 19, the basal three glabrous dorsally (gure 48) (... rst two are glabrous and third glabrous at proximal end ventrally).

Forcipular coxosternal teeth 41 4 with two median more or less fused and a large isolated lateral tooth bearing a small outer subsidiary (gure 49). Process of femoroid with one very low inner tooth.

Tergite paramedian sutures complete from 5, marginate from 7 (5 and 8). Without keels, corrugations or spines. Tergite 21 with median longitudinal depression occupying posterior third of the tergite.

Sternite paramedian sutures complete from 2 to at least 15, the middle part of each in a sulcus, with median longitudinal depression in anterior half and posterior median rounded depression from about sternites 13–19 (gure 51). Sternites without tubercles. Sternite 21 slightly narrowed posteriorly with a median longitudinal furrow. The hind border incurved (gure 52).

Coxopleural process narrow and of moderate length, with two end spines and a subapical spine, one lateral and one dorsal spine (gure 53). Left end leg prefemur with four ventrolateral, three medial, two dorsomedial spines and a corner spine.

Two tarsal spines on leg 2, one on leg 3 and 7–20. Legs 4–6 are missing. End leg without tarsal spine.

Remarks

Attems (1930) gave O. completus as a synonym of O. astenus but it runs down to O. politus Karsch, 1881 in his key. Attems presumably misread Chamberlin’s description. The specimen compares well with the population of O. politus from Rennell Island, also in the Solomons, described by Lewis (2000). Otostigmus completus is thus a junior synonym of O. politus .
