Agalliana pauliana Evans 1953: 105 , figs 28, 28a, 29. Holotype 3, Madagascar [NMNH, examined].
Measurements. Male 3.80–3.90 mm long, 1.15–1.19 mm wide across eyes.
Head and thorax (color). Ground color dark brown with ochraceous markings. Crown ( Fig. 10 View FIGURES 9 – 14 ) ochraceous with four dark brown maculae: one pair of elliptical spots equally distant between eyes and median line, contiguous to pronotum, and one transverse mark behind each eye. Face ( Fig. 26 View FIGURES 23 – 33 ) with ochraceous macula extending from one antennal ledge to the other one. Genae with pair of ochraceous markings on outer margins. Pronotum ( Figs 9–10 View FIGURES 9 – 14 ) with posterior 0.25 area ochraceous. Mesoscutellum with ochraceous lateromedial markings. Forewings ( Figs 9–10 View FIGURES 9 – 14 ) chocolate brown, except parts of inner claval veins, claval commissure, costal margin, claval suture, ochraceous; hyaline area along costal area in middle. Legs ( Fig. 9 View FIGURES 9 – 14 ) ochraceous.
Morphology. Sternal apodemes ( Fig. 77 View FIGURES 70 – 85 ) of second abdominal segment extending to third sternum, elongate, separated from each other by a distance half their width at midlength.
Male genitalia. Pygofer ( Fig. 41 View FIGURES 34 – 41 ), in lateral view, with posterior margin broadly rounded with scattered minute tubercles ( Fig. 78 View FIGURES 70 – 85 ), and with a few scattered setae. Subgenital plates broad basally, tapering apically, without long hair-like setae. Styles ( Fig. 49 View FIGURES 42 – 53 ), in dorsal view, with inner fork bilobate apically, and outer fork with broad hooked apex; shaft with distal area bearing scattered setae. Connective ( Fig. 65 View FIGURES 62 – 69 ) well developed and highly sclerotized, about as broad anteriorly as midlength, and not fused to aedeagal base. Aedeagus ( Fig. 54 View FIGURES 54 – 61 ), in ventral view, symmetrical, simple, rather V-shaped in lateral view, preatrium and dorsal apodeme well developed, shaft slightly curved at midlength, in caudal view ( Fig. 65 View FIGURES 62 – 69 ) with apical well developed invagination and lateral margins slightly sinuate; gonopore subapical on ventral margin. Anal tube ( Fig. 41 View FIGURES 34 – 41 ), small, in lateral view, with segment X bearing pair of elongate processes strongly curved dorsally, forming right angle at basal half, with apical hook; outer margin of hook with two short projections: distal one spiniform and proximal one digitiform.

Remarks. The genus Agalliana was described by Oman (1933) based on the type-species Bythoscopus sticticollis (Stål 1859) . Members of Agalliana have been distinguished from other Agalliini by a single character, the coarsely punctate pronotum ( Oman 1934). The majority of the species of Agalliana , such as A. ensigera Oman ( Figs13–14 View FIGURES 9 – 14 , 33 View FIGURES 23 – 33 ), have a South American distribution with the exception of A. sticticollis which occurs in the Greater Antilles.
The punctate pronotum led Evans (1953) to place a species from Madagascar, A. pauliana , in this genus, despite the fact that the genus was previously recorded only from the New World. Other than that, several morphological features are dissimilar between other Agalliana species and that described by Evans. The main differences between them are given in Table 1 View TABLE 1 . Besides those, the diagnostic character of the punctate pronotum, is now known to occur also in other genera, such as Megagallia Linnavuori and Paulagallia Viraktamath.
There is some uncertainty regarding the type. Evans (1953: 105) clearly states that the type is a male and the allotype is a female, however, the type and allotype labels have apparently been switched. Among the species of Agallidwipa , male A. pauliana can easily be recognized by its characteristic coloration of the pronotum and most parts of the frontoclypeus being dark brown without any ochraceous spots. The type male appears to be a teneral specimen and the male genitalia is placed on card within a drop of resin. The species has dorsally hooked processes on segment X, and the aedeagus lacks processes. A. webbi (see below) also has a similar aedeagus but lacks processes on segment X.
