The Afrotropical species of the genus Paralimosina L. Papp, 1973, are discussed. Six new species, Paralimosina australis sp. n. (Rwanda, Burundi, South Africa), P. congoensis sp. n. (Republic of Congo), P. flavifacies sp. n. (Tanzania), P. heteroneura sp. n. (South Africa), P. paraustralis sp. n. (South Africa), and P. sinelineata sp. n. (South Africa) are described. The morphological variety among the Afrotropical species of Paralimosina seems to be the widest. Therefore, it is expected that many other new species will be described from the region in the future. An identification key to the new taxa is provided.
The genus Paralimosina L. Papp, 1973, includes a number of sphaerocerids of the subfamily Limosininae that have robust and strongly sclerotised bodies. Genera in this subfamily have the epandrium of the male genitalia fused below the anal opening. Furthermore, important differentiating characters are located on the cercal part of the epandrial complex as well as the hypandrium, surstylus, postgonite and phallus. On the female postabdomen, the shape, armature and ratios of tergite 8 and sternite 8 can be characteristic of particular species. Likewise, the epiproct (tergite 10), cerci (not fused with tergite 10) and spermathecae may exhibit features that are diagnostic at the specific level.
Paralimosina is a diverse genus with 27 described species in the Palaearctic and Oriental regions but hitherto it has not been recorded from the Afrotropical Region (Richards 1980; Roháček et al. 2001). Hayashi (2008a) named five other species from Thailand, and Hayashi (2007, 2008b) described four new species from Malaysia.
Although I found six new species during the course of this study, it is highly likely that more new species of Paralimosina will be discovered in the future, since the morphological variety among the Afrotropical species of Paralimosina seems to be the widest.
MATERIAL AND METHODS
This paper is based on studies of many double-mounted specimens of Paralimosina which are housed in the Hungarian Natural History Museum (HNHM; Budapest), National Museum (BMSA; Bloemfontein, South Africa), and KwaZulu-Natal Museum (NMSA; Pietermaritzburg, South Africa).
Abdomina of up to several (at least one) specimens of each species were removed and treated with 10% hot sodium hydroxide (NaOH) for several minutes and lactic acid, then rinsed, etc., in the standard way. Those abdomina with genitalia are now kept in glycerol in plastic microvials under the respective pinned specimens.
In the species accounts below, geographical names on specimen labels are given in their present-day spelling, whereas my annotations concerning label data are in square brackets.
The following abbreviations are used below: setae: ifr — interfrontal,fr-orb — frontoorbital, dc — dorsocentral, ad — anterodorsal, av — anteroventral, pd — posterodorsal, va — ventroapical; wing veins: R — radial veins, M — medial veins, M-M — posterior crossvein, R-M—M-M — inter-crossvein section of M1+2 (that is, veins are written consistently in upper case, including crossveins); other: T — abdominal tergite, S — abdominal sternite. For costal sections and indices see Roháček (1982).
I name the sclerotised structures above the phallobase and anterior ventrally to the cerci (with connections to epandrium and surstyli) as ‘subepandrial sclerite’ (‘medandrium’ of Roháček (1998), ‘decasternum’ auctorum), although its origin may be even more complex.
Genus Paralimosina L. Papp, 1973
Type species: Paralimosina kaszabi L. Papp, 1973: 376, by monotypy.
Roháček and Papp (1988) described the genus correctly in respect of diagnostic features. However, below I will nevertheless stress the characteristics of the male and female postabdomen and genitalia.
Diagnosis: Body rather strongly sclerotised and in some species even granulose, variably with denser microtomentum or more shiny, despite presence of some microtomentum. Body length around 2.5 mm.
Head without inner orbitals, anterior fr-orb always clearly shorter than posterior pair. Frons with or without velvety black (or silvery) M-shaped mark (Roháček 1998: fig. 2). Facial plate normally convex, antennae not in deep hollow, or if in a shallow depression, edges are not sharp. Peristomals weaker, a genal seta present. Several (3–5) pairs of ifr, if one of them is very large, it emerges far from eye margin. First flagellomere not conical but if slightly so, never with rod-like projection. Eye normal or slightly reduced.
Mesonotum usually with only 1 or 2 dc pairs; when 3 dc present, then R4+5 slightly recurved (Roháček 1998: fig. 93) or eye strongly reduced; no presutural dc pair. No setulae between apical scutellars; disc of scutellum usually bare. Scutellum never velvety black-marked, with only 2 pairs of long marginal setae, disc always bare. Anepisternum without setae.
Mid trochanter without or with a short seta. Mid tibia always without ventral preapical seta, but usually with one va (sometimes reduced only in males). Long mid ventral seta on mid tibia present only in species with distinct va on mid tibia (Roháček 1998: fig. 75). Mid tibia with or without mid av. Mid basitarsus without long av and without ventral seta. Hind tibia with a long dorso-preapical seta, at most. Pulvilli and claws weakly developed; ventroapical spur of hind tibia mostly reduced.
Wing unicolorous, with cross-veins at most clouded in the Afrotropical species (there are numerous Oriental species with a patterned wing (Hayashi 2008a, b)). Wing without macrotrichia. First costal section basally with 2 shorter (paired) setae, one of them not longer than twice the length of the second, otherwise first costal section with short or medium-length setae only. Vein R4+5 sinuate or upcurving.
Abdominal tergites not reduced, rather well sclerotised, marginal setae variable. Male postabdomen less downcurved; male cerci and S5 vary (but are usually simple). Male S4 normally without processes; S5 simple, without medio-caudal armature. Synsternite with basic structure characteristic of taxa in the subfamily Limosininae. Right side sclerites of the postabdomen (cf. Papp 2008) usually discernible but seldom with characteristic shape. Hypandrium with ventral single or bifurcate appendage (Roháček 1998: fig. 33). Epandrium with one connection on each side to hypandrium. Surstylus long but mostly not very high, in an anterior and a posterior lobe, the latter without robust ventral spines (Roháček 1998: fig. 108). Phallus in two parts: basiphallus short but usually high, well sclerotised without epiphallus, distiphallus varying, mostly with large ventral lobe(s), always shorter than phallapodeme, which is strong. Ejaculatory apodeme always discernible but its sclerotisation varies; and since it seems to be asymmetrical, its detectable shape is dependent on its positioning.
Female with seven normal preabdominal segments, although the length of the 7th is variable. Postabdomen not telescoped. T8 consists of 2 lateral sclerites that have a pair of medially directed, narrow ventral processes, and may bear longer setae, mostly on the caudal margin. Features concerning S8 mostly species-specific. Epiproct (= T1O, or T9 auctorum) usually flat, with or without some setae that are of diagnostic value. Hypoproct (= S10, or S9 auctorum) larger in several species and with short setulae, which are sometimes very thick (peg-like). Cerci always short, not fused to T1O. Spermathecae 1+2, globular, vesiculate or subspherical, without acute projections. Sclerotised ducts usually short but the length (incl. length of individual ducts when they are paired) is species-specific.

Remark: The discovery of two such closely related species of the Afrotropical Paralimosina must make us aware of the possible existence of similar sister species in the region, i.e. of the need for genitalia preparations from specimens in the future.

Paralimosina sinelineata sp. n.
Etymology: From Latin sine (without) and linea (line), in reference to the absence of the M-shaped pattern on the frons.
Measurements in mm: body length 1.39 (holotype), 1.25–1.70 (paratypes), wing length 1.30 (holotype), 1.25–1.76 (paratypes), wing width 0.61 (holotype), 0.60–0.82 (paratypes).
Body brown, grey microtomentose, legs darker brown, tarsi only slightly lighter.
Frons without M-shaped mark, finely microtomentose brown, anterior part ochre. Four ifr pairs, anteriormost one prominent but not more than 0.05 mm. Antennae well separated. Medial seta on scape 0.06 mm long, genal seta 0.06 mm. First flagellomere with cilia 0.025 mm long (apical aristomeres broken off, so aristal cilia not measurable).
Anterior katepisternal seta only 0.04 mm long, posterior one 0.14 mm. Wing comparatively short, rounded, uniformly light brown, veins slightly darker, only costal vein darker brown. Basal seta on costa 0.09 mm. Costa overruns R4+5 by 0.02 mm. Second costal section 0.44 mm, third section 0.63 mm, costal index 0.71. R-M—M-M 0.19 mm, M-M 0.09 mm.

Male S5 (Fig. 55) broad and rather long with a broad, medial caudal extension that continued into a narrow membranous margin, which bears short hairs; there are mediumlength setae caudally, medially and also on lateral edges. S6–7 parts of synsternite strongly and broadly fused, medial part of S6 not extended much to the right, dorsal part of S7 small. S8 component of synsternite not fused to S7 part, broad on the left side dorsally, narrowed to the right side. No cereal lobes on epandrial complex but the connection of the two halves is broad sagittally (Fig. 57). Subepandrial sclerite almost as high as broad, ventral processes rather short. Hypandrium robust, with a large asymmetrical ventral process (Fig. 59). Surstylus (Fig. 58) with rounded, less sclerotised and melanised anterior part, with comparatively broad connecting part and rather large posterior section, which bears numerous long and medium-length setae. Phallapodeme ca 0.22 mm long, slightly curved in lateral view. Phallus (Fig. 60) short (<0.2 mm), basiphallus short but comparatively high, distiphallus with a dorsal, short process medially and a pair of subapical processes, having a serrated apex (Fig. 60). Postgonite with broad base, apical ⅓ narrowed, apex sharp (Fig. 61). Anterior edge with 2 medium-length (a little more than 0.02 mm) setae.
Female abdomen 0.75 as broad as long (postabdomen not at all telescopic), without any long setae, longest marginal setae of tergites only 0.08 mm. S2 trapezoid, medially very weakly sclerotised and melanised; as a result of NaOH preparation, it looks bipartite. S3–5 are ⅓ to ⅖ as broad as tergites. S7 in its natural position (arched) 0.10 mm long and 0.25 mm broad. S8 shield-shaped, with broadly rounded caudal margin, 0.12mm wide, 0.11 mm long with setae ca 0.05–0.06 mm in length on its apical 0.6. Syntergite 0.4 section as long as wide, T1 part weakly sclerotised and light medially, T2 component less darkly melanised medially but not less sclerotised than other parts. T3–6 are 0.25, 0.25, 0.23, 0.2 as long as width of abdomen at their position. T7 is 0.3′ as broad as syntergite. T8 in 2 completely laterally placed, comparatively large sclerites (ca 0.11 mm long and 0.15 mm broad), and with a ca 0.04 mm long and nearly 0.20mm wide membranous central part. Epiproct 0.175 mm broad but only 0.050 mm long, no setal pair on epiproct. Hypoproct 0.18 mm in width, broader than a semicircle, with numerous marginal setulae 0.020–0.025 mm long. Cerci strongly oblique to the body axis (ca 45°), with a seta 0.11 mm in length and several shorter pairs of setae. Spermathecal ducts not long, so spermathecae are situated in the 7th segment. Spermathecae pear-shaped, 0.045–0.050 mm broad and 0.055 mm long, apical part of the paired ones slightly obtuse. Proximal part of the ducts extended, the single one slightly and the paired ones more markedly so, where diameter of duct is a little more than 0.02 mm. Spectacles-shaped sclerite distinct, with more obviously sclerotised central part.
