Type material.
HOLOTYPE. Female: Madagascar , Behara, Museum Paris, I·38, [A.] Seyrig (MNHN). PARATYPES. 13F, 9M: same data as holotype, SAM-HYM-P031800 (MNHN, SAMC, USNM); 6F, 4M: Madagascar ,Behara, Museum Paris, XI·38, [A.] Seyrig, SAM-HYM-P044099 (MNHN, SAMC, USNM).
Note.
Behara (24°57'S, 46°23'E) is situated in south-eastern Madagascar (in the district of Amboasary Sud, which is part of the Anosy Region) near Tôlanaro (formerly Fort Dauphin), the latter was the first French settlement in Madagascar. There are numerous settlements in Madagascar with the name Behara, but based on an annotated copy of the map in Seyrig’s 1932 paper in combination with the fact that he lived in Tôlanaro for many years, the above locality (which is the largest and most well known settlement named Behara) was deemed to be the most likely (Rousse pers. comm.). André Seyrig collected throughout Madagascar from 1921 to 1944, but his collecting effort was focused down the middle of the southern part of the island from Antanarivo to Tôlanaro and east of Antanarivo to the coast (see map in Seyrig 1932 and Figure 1 in Rousse et al. 2011). Seyrig’s insect collection and manuscripts were given by his widow to the Muséum National d’Histoire Naturelle, Paris, MNHN ( Rousse et al. 2011) and unless there are specimens collected by him from elsewhere in Madagascar that remain undiscovered in the Paris or other museums, current evidence suggests a restricted distribution for this species. In addition extensive inventory surveys conducted by Brian Fisher and colleagues from the California Academy of Sciences across Madagascar in recent years have so far not produced any specimens of this species (that we are aware of; many samples remain to be sorted from the CASC Madagascar project (R. Zuparko, pers. comm)) suggesting that the species is rare or probably more likely to be localized in distribution. Seyrig collected 32 specimens in the months of January and November 1938 suggesting that it is not rare where it occurs.
Distribution.
Madagascar (currently only known from Behara).
Etymology.
Named after André Seyrig (1897-1945) collector of the type series and prolific collector of many other faunal and floral taxa from Madagascar. Noun in the genitive case.
Diagnosis.
Belongs to the newly erected Paramblynotus seyrigi species-group (see above). Female with 13 (male with 14) segmented antennae ( Fig. 1A View Figure 1 ); F1 shorter than F2; flagellum not widening toward apex; ocellar plate not raised; ocelli large, their diameter as great as distance between lateral and median ocellus. Vertex with two distinct lateral carinae extending from each torulus towards lateral ocelli, reaching posteriorly as far as in line with median ocellus; strongly keeled medial carina present between toruli extending towards median ocellus ( Figs 2C; 2E View Figure 2 ). Occiput straight in dorsal view, smooth without a carina ( Figs 1C-D View Figure 1 ). Lower face protruding in lateral view. Single submedian pronotal depression ( Fig. 2A View Figure 2 ). Pronotal crest not raised. Lateral carina of pronotum distinct. Posterior mesoscutum and scutellum contiguously flat in lateral view ( Fig. 1C View Figure 1 ). Mesoscutum smooth, shiny with remnants of transverse costae; notaulices complete extending to anterior margin of mesocutum; median mesoscutal impression present reaching halfway to anterior margin ( Figs 1D-F View Figure 1 ). The two scutellar foveae each with four subcarinae creating a transverse row of 10 longitudinally elongate subfoveae ( Fig. 1F View Figure 1 ). Upper mesopleuron and speculum glabrous ( Fig. 2B View Figure 2 ). T6 largest dorsally, T 8 exposed ( Figs 2F View Figure 2 ; 3A View Figure 3 ). Wings clear with three darker vertical patches, a small patch either side of the basalis vein, a larger patch subapically between RS and M+Cu and an apical band confluent with the wing margin ( Fig. 3B View Figure 3 ).
Comments.
This species, along with Paramblynotus zohy sp. n. and Paramblynotus behara sp. n. represent the first records of Paramblynotus from Madagascar.
Description.
FEMALE. Length 5.2-8.0 mm (holotype: 6.3 mm ). Head, antennae (except for terminal segments which are darker), pronotum, legs and proximal third of metasoma brownish-orange; rest of mesosoma dark brown; rest of metasoma orange ( Fig. 1A View Figure 1 ). Wings transparent; with three darker vertical patches, a small patch either side of the basalis vein, a larger patch subapically between RS and M+Cu, and an apical band confluent with the wing margin ( Fig. 3B View Figure 3 ). Entire head with the exception of the genae and occiput strongly pubescent. Eyes prominent, bulbous, but not laterally extended much beyond outer margin of genae in frontal view ( Fig. 2C View Figure 2 ). Antenna 13 segmented; F1 shorter than F2; flagellum not widening toward apex. Vertex smooth, ocellar plate not raised; ocelli large, their diameter as great as distance between lateral and median ocellus ( Figs 2C; 2E View Figure 2 ). Face punctate-rugose, humped between toruli and clypeal margin, protruding in lateral view; antennal scrobe mostly smooth with minute punctuation. Vertex with two distinct lateral carinae extending from each torulus, defining outer margin of scrobe, towards lateral ocelli, reaching posteriorly as far as in line with median ocellus; strongly keeled medial carina present between toruli extending towards median ocellus ( Figs 2C; 2E View Figure 2 ). Occiput straight in dorsal view, smooth without a carina. Lower face with strong excavations (with weak vertical carinae) defining upper clypeal margin, and containing anterior tentorial pits ( Fig. 2D View Figure 2 ). Clypeus smooth. Genae with distinct foveae along eye margin, polished between these foveae and genal carina. Mesosoma strongly pubescent. Anterior plate of pronotum puberulous. Pronotum dorsomedially with swollen rim without any crest. Lateral carinae of pronotum strong, fading dorsomedially. Lateral surface of pronotum foveate. Dorsal pronotal area smooth with minute punctures, Mesoscutum smooth, shiny with remnants of transverse costae; notaulices complete, extending to anterior margin of mesocutum; median mesoscutal impression present reaching halfway to anterior margin. The two scutellar foveea each with four subdivisions creating a transverse row of 10 longitudinally elongate subfoveae ( Fig. 1F View Figure 1 ). Scutellum medially smooth with sparse punctures, peripherally areolate-punctate. Posterior mesoscutum and scutellum contiguously flat in lateral view. Mesopleural triangle defined without ventral curved carina, strongly pubescent; upper mesopleuron glabrous, smooth, anteriorly and ventrally pubescent with minute punctures; median longitudinal impression percurrent with evenly spaced transverse carinae; speculum glabrous, smooth ( Fig. 2B View Figure 2 ).
Metanotal-propodeal complex strongly excavated, excavations bordered by strong carinae. Metepisternum dorsally excavated with pubescence, medially polished with indications of minor rugose remnants, ventrally pubescent. Dorsellum with two strong medial foveae; laterally strongly excavated with fine pubescence in lateral depressions. Lateral propodeal carina present; median longitudinal propodeal carina well-defined, crossed by wrinkled transverse and longitudinal carinae extending onto nucha ( Fig. 1F View Figure 1 ). Rs+M of forewing defined, but nebulous where it arises from basal vein at posterior third. Mar ginal cell 2.8 times as long as wide ( Fig. 3B View Figure 3 ). Abdominal petiole very short, polished, 0.25 times as long as wide in dorsal view ( Figs 1C-D View Figure 1 ). Posterior ventral margin of metasomal T7 sinuate ( Fig. 2F View Figure 2 ). T8 well exposed, with a patch of scattered long setae posteriorly ( Fig. 3A View Figure 3 ). Ventral portions of T2-T7 covered by sternum 3. Relative dorsal length of T3-8: 27:15:15:46:13:8. Tergites dorsally finely punctate; laterally and ventrally polished. All legs sparsely punctuate, strongly pubescent, except metacoxae dorsally glabrous, smooth. Mesotibial outer spur shorter than inner spur; metatibial spurs subequal in length. Ratio of first metatarsomere to the remaining 4 metatarsomeres combined: 0.70.
MALE. Length 4-5.5 mm. Very similar to female except for abdominal petiole, which is much more elongate, T2 as long as wide in dorsal view and twice as long as high in lateral view. Tergites 6-8 each with a dorsal terminal area of setiferous punctures, rest of tergite polished.
