Genus PTECTISARGUS Lindner

Ptectisargus Lindner, 1968: 3 . Type species, Ptectisargus lucidus Lindner, 1968 , by monotypy.

Ptectisargus abditus (Lindner) . Comb. nov.

Ptecticus abditus Lindner, 1936: 37 . HT ♀ [ SMNS]: Madagascar: Bekily.

Chrysochroma laetum Lindner. 1966b: 7 . HT ♂ [ MNHN]: Madagascar: Sakaraha. Syn. nov. Ptectisargus lucidus Lindner, 1968: 3 . ST 4 ♂, 1 ♀ [ MNHN] ; 1 ♂, 1 ♀ [ SMNS]: Madagascar: Bekily. Syn. nov.

We examined the female holotype of Ptecticus abditus [SMNS] ( Fig. 27 ), the male holotype of Chrysochroma laetum [MNHN], and two male syntypes of Ptectisargus lucidus [SMNS, MNHN] ( Fig. 28 ), and we consider all of them conspecific.

Ptectisargus brunneus (Lindner) . Comb. nov.

Ptecticus brunneus Lindner, 1936: 38 . HT ♀ [ SMNS]: Madagascar: Andreba.

We have studied the female holotype [SMNS], and the species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230).

Ptectisargus cingulatum (Lindner) . Comb. nov.

Chrysochroma cingulatum Lindner, 1968: 5 . HT ♀ [ MNHN]: Madagascar: Mt. Tsaratapana , 1400 m.

We have studied the female holotype [MNHN], and the species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230).

Ptectisargus flavifrons (Lindner) . Comb. nov.

Chrysochroma flavifrons Lindner, 1968: 6 . HT ♀ [ MNHN]: Madagascar: Ranomafana.

We examined the female holotype of Chrysochroma flavifrons [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231).

Ptectisargus flavomarginatus (Loew) . Comb. nov.

Chrysonotus flavomarginatus Loew, 1857: 263 . ST ♀ [ NHRS]: Mauritius.

We did not examine the type of this species, but the description by Loew fits specimens collected in Madagascar very well. The narrow elongated abdomen, lower calypter with a very elongated projection and the color pattern place this species in the genus Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231).

Ptectisargus gracilipes (Lindner) . Comb. nov.

Ptecticus gracilipes Lindner, 1936: 40 . HT ♀ [ SMNS]: Madagascar: Andreba.

We examined the female holotype of Ptecticus gracilipes [SMNS] and this species fits well with the concept of Ptectisargus .

Ptectisargus keiseri (Lindner) . Comb. nov.

Chrysochroma keiseri Lindner, 1966b: 6 . HT ♂ [ MNHN]: Madagascar: Montagne d’Ambre.

We examined the male holotype of C. keiseri [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231). The type series of Ptectisargus lindneri James is mixed and the male “ Allotype ” [BMNH] is conspecific with P. keiseri , while the female holotype [BMNH] is a different species. The female holotype is from the dry SW of Madagascar, while the male is from nearly the opposite corner of Madagascar, from the NE, which has a very different climate, and therefore it is not a surprise that the two specimens belong to different species. The holotype of P. lindneri has dark brown wing veins, a brown scutellum and the hind tibia being dark brown on the basal third and white on the apical 2/3 and the hind tarsi are dark brown, while P. keiseri has orange brown wing veins, a green metallic scutellum and the hind legs all light brown.

Ptectisargus longestylum (Lindner) . Comb. nov.

Chrysochroma longestylum Lindner, 1966b: 8 . ST 1 ♂ [MNHN], 1 ♂ [MRAC]: Madagascar: Ahitsitondrona.

We examined both male syntypes of C. longestylum [MNHN, MRAC] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231).

Ptectisargus punctum (Lindner) . Comb. nov.

Chrysochroma punctum Lindner, 1968: 6 . HT ♂ (stated ♀) [ MNHN]: Madagascar: Rogez , Forêt Côte Est.

We examined the male holotype of C. punctum [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232).

Ptectisargus ranohira (Woodley) . Comb. nov.

Chrysochroma ptecticoides Lindner, 1966b: 5 . ST 2 ♂, 1 ♀ [ MNHN, NMB, SMNS]: Madagascar: Ambato-Boeni and Ranohira . Preoccupied, primary homonym of Chrysochroma ptecticoides Lindner, 1935 . Chrysochroma ranohira Woodley 2001: 232 . New name for Chrysochroma ptecticoides Lindner, 1966b .

We examined a male syntype of C. ptecticoides [MNHN] and a female syntype [SMNS] and this species fits well into the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232).

Ptectisargus unicolor (Lindner) . Comb. nov.

Chrysochroma unicolor Lindner, 1968: 7 . HT ♀ [ MNHN]: Madagascar: Ivondro.

We examined the female holotype of C. unicolor [MNHN] ( Fig. 32 ) and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232).
