Eulioptera bartolozzii View in CoL n. sp.

( Figs. 1a– 1g View FIGURE 1 )

Material examined. Kenya, 19 kms West of Malindi on the road Malindi-Tsavo, 27.IX–14.X.1992, L. Bartolozzi (1♂ holotypus) ( MZUF) .

Measurements (mm). Male. Body length: 12.6; length of pronotum: 2.8; height of pronotum: 2.6; length of hind femora: 15.0; length of tegmina: 21.9.

Diagnosis. E. bartolozzii n. sp. is a small sized Eulioptera , characterized by the male subgenital plate elongate and upcurved, divided into two laterally flattened lobes, and three black spots on each stridulatory area of left and right tegmina.

Description. Male ( Figs. 1a, 1b View FIGURE 1 ). Colour. Yellowish with black spots on the stridulatory area and the hind margin of tegmina. Head and antennae. Head typical of the genus, eyes round prominent, fastigium of vertex compressed, just raised at the apex, narrower than scapus, not contiguous with fastigium of frons. Antennae exceeding the tip of tegmina. Pronotum without lateral carinae, anteriorly straight, posteriorly rounded, longer than high. Wings. Hind wings extending beyond tegmina by quarter-fifth of latter. Stridulatory area of left tegmen little raised, mirror on right tegmen wide, oval ( Fig. 1c View FIGURE 1 ). Stridulatory file ca. 0.9–1.0 mm, consisting of ca. 140 more or less evenly spaced teeth ( Fig. 1d View FIGURE 1 ). Legs. Fore coxae armed with a small spine. Fore femora with 6 small spines on inner margin, mid femora armed with 3–4 couples of spines on lower margins, hind femora armed with 4–5 spines on outer and 2–3 on inner lower margins. Fore tibiae with 5 spines on inner and outer lower margins, mid tibiae with 10–11 spines on outer lower margin and 6–7 on inner lower margin. Hind tibiae with a dozen spines on inner and outer lower margins + 3 spurs on each side. Abdomen. Tenth tergite unmodified, cerci thin, long and incurved, with round apex. Subgenital plate divided into two lobes, laterally flattened and apically rounded, gently upcurved ( Figs. 1e, 1f, 1g View FIGURE 1 ).

Female. Unknown.

Etymology. E. bartolozzii n. sp. is named in honour of Luca Bartolozzi, entomologist, collector of the specimen, and curator of the Museum of Zoology of the University of Florence, Italy.

Affinities. E. bartolozzii n. sp. is similar to E. zambesiana Massa, 2022 , which has a much longer male subgenital plate and a bigger size (17.3–20.2 mm) ( Massa 2022) ( Fig. 1h View FIGURE 1 ), to E. montana Ragge, 1980 (Chyulu Hills, Kenya), which has a different male subgenital plate ( Fig. 1i View FIGURE 1 ), a dark spot on the male stridulatory area, a little different stridulatory file (ca. 125 teeth). It is also vaguely similar to E. r. reticulata (Brunner von Wattenwyl, 1878) , which, however, has a different male subgenital plate and pointed cerci ( Fig. 1j View FIGURE 1 ), and to E. monticola Ragge, 1980 , characterized by red-brown spots on much of the body and a black mark on the stridulatory area; cerci are less incurved and the subgenital plate is shorter than in E. bartolozzii n. sp. ( Fig. 1k View FIGURE 1 ) ( Ragge 1980). E. carrolli Naskrecki & Guta, 2019 , E. mutembai Naskrecki & Guta, 2019 , and E. iolandae Massa, 2021 have differently shaped male subgenital plates (Naskrecki & Guta 2019, Hemp 2021, Massa 2021).
