description: Mislocatus gen. nov.
(Figs 54–61)
Type species: Ceroptera ealensis Vanschuytbroeck, 1951: 11, by present designation.
Gender: masculine.
Etymology. I name this new genus as ‘ Mislocatus ’ (Latin: wrongly placed), since its type species had formerly been placed in the genus Ceroptera, which it does not relate to.
Diagnosis. Subcostal vein conspicuous: clearly detectable to the 4/5 length of R1. Male postabdomen and genitalia are very distinct: medial caudal part of sternite 5 with a better sclerotised area, which forms half of a ring, this medio-caudal part continued in a pair of straight thorns and a peculiar pair of long sickle-shaped processes with sharp long thorn-like apex and blunt short black pegs on its caudal margin; synsternite fused to rather large laterally and ventrally directed right side sclerites; sternite 8 part large, comparatively long, epandrium simple without the large epandrial processes of Ceroptera spp., subepandrial sclerite very small (Fig. 60) and strongly connected to cerci, cercus small, very shortly fused sagittally with a pair of strong setae, surstylus simple, horizontal with numerous long setae, basiphallus comparatively large compact without epiphallus, distiphallus long and comparatively thin, phallapodeme rod-like without discus-like basal thickening as in Ceroptera spp. The genus was properly fitted in Papp’s (2008) key to couplet 25.
Description. See Papp (2008), p. 62. No longer (upcurved) genal seta, postocular seta indistinct.
Legs. Fore femur with some long posteroventral setae but no robust basal setae. Mid tibia without a posterodorsal seta in basal half.
Wing unicolorous, costa produced markedly beyond apex of R4+5.
Abdomen. Preabdominal sclerites other than male sternite 5 normal, although tergites 3 to 5 transverse, more than twice broader than long, weakly sclerotised with rather long marginal setae.
Male. Preabdominal tergites and sternites not reduced. Sternite 5 (Fig. 54) extremely large, not only broad but long with numerous very long setae on all its surface. Medial caudal part of sternite 5 with a better sclerotised area, which forms half of a ring and embraces less sclerotised and melanised area, which bears thin setae. This mediocaudal part continued in a pair of straight thorns and a peculiar pair of process: long sickle-shaped process with sharp long thorn-like apex and blunt short black pegs on its caudal margin (Fig. 55). Figure 56 on synsternite drawn in an unusual view, is a key figure to illustrate structure of the postabdominal sclerites. Synsternite fused to rather large right side sclerites; sternite 8 part large, comparatively long. Epandrium simple without large epandrial processes of Ceroptera sp. (see e.g. Papp 2008: fig. 6). Subepandrial sclerite very small (Fig. 60), and strongly connected to cerci. Cercus (Fig. 61) small, very shortly fused sagittally with a pair of strong setae. Surstylus (Fig. 58) simple, horizontal with numerous long setae. Basiphallus comparatively large, compact without epiphallus (Fig. 57, cf. e.g. Papp 2008: fig. 4). Distiphallus long and comparatively thin. Phallapodeme (Fig. 57) rod-like without discus-like basal thickening as in Ceroptera spp. Postgonite (Fig. 59) long simple with blunt apical part.
Female abdomen and genitalia. Syntergite 1+2 well sclerotised but short, only 0.15 mm, its longest marginal setae 0.15–0.16 mm. Tergites 3 to 5 transverse, 0.05 mm long but as least 0.13 mm broad, weakly sclerotised with rather long marginal setae. Sternites 2 to 5 all weakly sclerotised with measurements (in mm): 0.15 x 0.14, 0.17 x 0.14, 0.17 x 0.15, 0.15 x 0.17. Sternite 8 simple semicircular with 3 pairs of short marginal setae. Tergite 8 not divided though less melanised sagittally. Tergites 6 and 7 as well as sternites 6 and 7 all quadratic, broader than long.
Epiproct shield-shaped with a long dorsal pair of setae. Cercus 0.07 mm long with 4 pairs of long setae (dorsal, apical, lateral, ventral subapical), longest one 0.010 mm (!). Hypoproct 0.08 mm broad but only 0.025 mm long with thin marginal setae. Spermathecae long cylindrical (0.06–0.065 mm long, 0.025 mm broad), distal end rounded. Sclerotised ducts only 1/2 as long as width of spermatheca.
Remark. I found a female specimen in the BMSA material at a late phase of the preparation of the MS; this is why I did not make figures of the female genitalia, but I give a detailed description instead.
