Material examined

Holotype

MADAGASCAR: ♀ (examined on photographs), [Madagascar, coll. Lambert.] [environs de Tananarive] [Type] [ Belbina blotei Lall., V. Lallemand det., 195] [RMNH. INS.780532], Tananarive (Antananarivo), 18°55’ S, 47°31’ E (RMNH). – Note: “Lambert” = Lamberton.

Paratypes

MADAGASCAR: 1 ♀ (examined on photographs), [Madagascar, rec. Lamberton] [ environs de Tananarive] [ Belbina blotei Lallemand, V. Lallemand det., 195] [Paratype] [RMNH.INS.780531] (RMNH); 1 ♂, 1 ♀, [ environs de Tananarive] (FSAG). Note: Lallemand (1959) stated that all types are deposited in RMNH but he actually retained 2 paratypes in his collection (now in FSAG).

Additional material

MADAGASCAR: 1 ♂, Mahajanga Prov., Forêt de Tsimembo, 8.7 km 336° NNW of Soatana, 19°1’17” S, 44°26’26” E, 20 m, 21–25 Nov. 2001, at light in tropical dry forest, Fisher, Griswold et al. (CAS); 2 ♀♀, near Tananarive, Lamberton (RBINS); 2 ♀♀, Morondava à Mahabo, Last 1854-91, 20°20’ S, 44°28’30” E (MNHN); 1 ♂, Madagascar (NMPC); 1 ♂, no data (NCSU).

1 ♀, erroneously labelled Soekaboemi, Java (INHS).

Male genitalia

Dark red (Figs 15–16); pygofer higher than long and with posterior margin concave in middle in lateral view (Fig. 15); anal tube slightly elongate, 1.16 times longer than broad at apex and with lateral margins bisinuate in dorsal view (Fig. 16); margin of anal opening pointed posteriorly (Fig. 15) and hiding lateral margin apically in dorsal view (Fig. 16); gonostyli elongate, 1.18 times longer than high (dorsal process included), strongly surpassing apex of anal tube and acutely rounded at apex in lateral view (Fig. 15); ventral margin straight on basal 1/5, then strongly excavate (Fig. 15); dorsal margin with basal strong digitiform process projecting laterodorsally, strong hook laterally at middle of process projecting posteroventrally and posterior margin of process excavate between apex and hook (Fig. 15); apex of digitiform process rounded and broad in dorsal view (Fig. 16).

Remarks

Belbina bloetei is a member of the falleni + group, showing strong basodorsal digitiform process on gonostyli. It can be separated (1) from B. falleni, B. laetitiae sp. nov., B. lambertoni and B. pionneaui by the more strongly concave ventral margin of the gonostyli in lateral view; (2) from B. falleni by the less excavate dorsal margin of the gonostyli in dorsal view; (3) from B. laetitiae sp. nov. and B. lambertoni by the more acute apex of the gonostyli in lateral view; (4) from B. pionneaui by the more rounded apex of the basodorsal digitiform process of the gonostyli.
