description: Notophlebia Peters & Edmunds 1970
Type species: Notophlebia hyalina Peters & Edmunds 1970.
References: Peters & Edmunds 1970: larva (as " Nathanella "), imago; Sivaramakrishnan & Peters 1984: larva and imago.
Besides characters of Iscini (see above), known species of Notophlebia share the following common characters:
In larva:
(1) Labrum has both transverse setal rows (characteristic for Atalophlebopectinata—see Kluge 2009) transformed to fields of irregularly arranged setae (Fig. 5; Peters & Edmunds 1970: 261; Sivaramakrishnan & Peters 1984: Fig. 14).
(2) Median projections of superlinguae project distad of hypopharynx (Fig. 4; Sivaramakrishnan & Peters 1984: Fig. 16).
(3) Larval tibiae, besides setae present in most Leptophlebiidae (stout pointed bipectinate setae on inner side of fore tibia, stout setae on inner side of middle and hind tibiae, stout setae on outer side of hind tibia and long hairlike setae on outer side of all tibiae) bear an oblique longitudinal row of stout setae on anterior (dorsal) side. In N. ganeshi sp.n. this row is equally developed on all legs: on fore leg (Figs 2a; 14), on middle and hind legs (Fig. 3); on all three pairs of legs setae of this row are unequal, elongate, stout and blunt (as in Fig. 54a). In N. jobi row of such setae is present on middle and hind legs (Fig. 54a), but on fore leg it is substituted by a field of irregularly situated very long pointed filtering setae (Fig. 53a).
(4) Larval abdominal terga I–VI have no posterolateral projections; terga VII and VIII have short blunt projections; tergum IX has long blunt projections (Fig. 3) (plesiomorphy; unlike Isca, whose abdominal terga I– VIII have no projections, and only tergum IX has long blunt projections).
(5) Tergalii [see Iscini (5)] are modified as following. Each tergalius I–VI has each of two lamellae blunt (instead of pointed in Isca and most other Leptophlebiidae); tergalius II is a little longer than tergalius I; tergalii III–VI are gradually shorter from anterior to posterior ones, having similar width; tergalius VI is much smaller; tergalius VII is lost (Figs 31–34, 40–45). All tergalii participate in rhythmic respiratory movements, and movements of most anterior tergalii are most intensive (in contrast to Choroterpini, Indialis, Nathanella and Petersula, whose tergalii of first pair are immobile).
In adult:
(6) Fore wing of all 3 species has the same coloration: proximal half of subcostal field is darkened, while remainder membrane is lighter; cross veins in proximal part of wing are bordered by brown, while remainder cross veins are light (Fig. 1; Peters & Edmunds 1970: Fig. 346; Sivaramakrishnan & Peters 1984: Fig. 3). Besides this, fore wings have following characters: long and narrow, with convex proximal-anal margin (unlike Nathanella); MP without symmetric fork (unlike some species of Isca); imago has marginal setae as in subimago (unlike some species of Isca). Hind wings are lost [see Iscini (8)].
(7) Penis [deeply separated—see Iscini (12)] has following characteristics common for all 3 species: Apically each penis lobe bears a slender pointed serrate projection—either curved [in N. jobi (Sivaramakrishnan & Peters 1984: Fig. 3)], or straight [in N. ganeshi sp.n. and N. hyalina (Figs 23, 24, 26–30; Peters & Edmunds 1970: Fig. 349)]. Distal part of gonoduct is covered by cuticle both in imago and larva (Figs 37, 45) (the same in some other taxa).
Variable characters of Notophlebia. Mouthpart structure strongly varies among species: N. ganeshi sp.n. has non-modified mouth apparatus [except labral setae—see (1)]; Notophlebia jobi has mouth apparatus of « Dilatognathus - type », with following modifications: maxilla with a long inner-apical tusk and without apical flange, dentiseta and apical-ventral pectinate setae; maxillary palp filtering, with 1 st palpomere strenghted, 2 nd and 3 rd palpomeres elongated and 3 rd palpomere bearing long setae arranged in transverse rows; labial palp filtering, with 2 nd palpomere strongly shortened and 3 rd palpomere strongly elongated and bearing long setae arranged in transverse rows (Figs 46–51; Sivaramakrishnan & Peters 1984: Fig.13–17; Kluge 2012: Table 1).
Dimensions. Fore wing length (and approximated body length) 6–8 mm.
Distribution and composition. South-western India (Western Ghats). Three species: Notophlebia hyalina Peters & Edmunds 1970; N. jobi Sivaramakrishnan & Peters 1984; N. ganeshi sp. n. Among them, larvae are known only for N. jobi and N. ganeshi.
