Paramblynotus yangambicolus species-group

Remarks.

Historically this taxon has been recognized variously at generic ( Decellea Benoit, 1956) or subgeneric level ( Liu et al. 2007). Decellea was synonymized with Paramblynotus by Weld (1962); followed by re-establishment of generic status by Ronquist (1995); and subsequent re-synonymisation based on phylogenetic analyses, which showed this species-group to be deeply nested within the Paramblynotus clade ( Liu et al. 2007).

Previously the species-group was only known from the African mainland with three described species ( Paramblynotus mixtus Liu et al., Paramblynotus alveolatus Liu et al. and Paramblynotus yangambicolus Benoit). We describe two further species from Madagascar (Paramblynotus behara sp. n. and Paramblynotus zohy sp. n.).

Diagnosis.

This species-group is characterized in females by excavations (spiracular peritremata) on the terminal portion of T8 associated with the spiracle ( Figs 7B ; 9 D ; 12A-B ), not referred to by Liu et al. (2007). A distinct pronotal crest is present, medially forming a conspicuous, slightly backward pointing, ridge-like tooth ( Figs 4C ; 6C ; 8C-D ; 10C ). The mesoscutum has rough discontinuous transverse costae produced into irregularly raised and slightly backward pointing teeth ( Figs 4C-D ; 6C-D ; 8E-F ; 10C-D ). The speculum is longitudinally costate ( Fig. 11D , and the median propodeal area is not delimited by lateral propodeal carinae.

Key to species of the Paramblynotus yangambicolus species-group (modified from Liu et al., 2007)

1	Forewing with RS+M vein arising at or very close to base of basal vein ( Figs 5B ; 12C ) (Madagascar)	2
-	Forewing with RS+M vein arising at basal third or mid-way up basal vein ( Figs 9B; 9E ) (Africa)	3
2	Head and mesosoma black ( Figs 4C-D ). Abdominal tergite 2 (petiole) dorsally sparsely variolate with confused, weak, longitudinal carinulation ( Fig. 4F ); laterally with strong, widely spaced longitudinal carinae ( Fig. 4E ). RS+M, basal vein and M+Cu1 nebulous ( Fig. 5B ). RS+M arising from base of basal vein, this juncture represented by a pigmented spot ( Fig. 5B ). (Female unknown)	Paramblynotus behara sp. n.
-	Head pronotum, mesoscutum and scutellum reddish-brown ( Figs 10 C-D ). Abdominal tergite 2 (petiole) densely longitudinally carinate ( Fig. 11E ). RS+M, basal vein and M+Cu1 distinct ( Fig. 12C ). RS+M arising slightly above base of basal vein ( Fig. 12C ). (Female T8 with two excavations, a smaller circular one surrounding the spiracle and a second larger oval one adjacent to the first and extending to posterior margin) ( Figs 12A-B )	Paramblynotus zohy sp. n.
3	Body length about 4 mm. Body colour entirely dark ( Fig. 6A ). Eyes prominent, protruding distinctly beyond genae ( Fig. 6E ). Median frontal carina almost reaching clypeus. Antennal scrobes rugose. Speculum distinctly longitudinally carinate ( Fig. 6C ). Upper mesopleuron foveate-reticulate. Mesoscutellum sloped posteriorly ( Fig. 6C ). Wings entirely transparent ( Fig. 6A ). Metasoma somewhat, but not strongly, compressed laterally. T6 almost about the same size as the three preceding tergites ( Fig. 6F ). Sterna 4-6 entirely covered by sternum 3	Paramblynotus mixtus
-	Body length about 6-10 mm. Head and mesosoma dark, metasoma yellow to brown ( Fig. 8A ). Eyes not protruding distinctly beyond genae ( Fig. 9A ). Median frontal carina absent in lower face. Antennal scrobes entirely longitudinally carinate. Speculum very finely and superficially carinate ( Fig. 8E ). Upper mesopleuron entirely longitudinally costate. Mesoscutellum raised posteriorly, forming a flat dorsal surface ( Fig. 8C ). Forewing evenly ferruginous with darker marginal cell and a dark narrow strip along anterior-interior margin of the first submarginal cell ( Fig. 9B ). Metasoma strongly compressed laterally ( Fig. 9B ). T6 distinctly larger than any of the 3 preceding tergites ( Fig. 9C ). Sterna 4-6 exposed, not covered by sternum 3	4
4	Face evenly curved in lateral view. Genae ventrally strongly expanded posteriorly. Median mesopleural impression distinct. Lower mesopleuron densely punctate with pubescence. Apical teeth of metatibia rounded apically; first metatarsomere 2.0 × length of remaining 4 metatarsomeres combined	Paramblynotus alveolatus
-	Face distinctly raised medially and curved inward ventrally in lateral view ( Fig. 8D ). Median mesopleural impression usually obscured by extension of longitudinal carinae in upper mesopleuron ( Fig. 8C ). Lower mesopleuron glabrate and sparsely punctate with sparse pubscence. Apical teeth of metatibia pointed apically ( Fig. 9C ); first metatarsomere 1.5 × length of remaining 4 metatarsomeres combined	Paramblynotus yangambicolus
