description: 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).
