Four New Species of Death Watch Beetles of the Genus Lasioderma Stephens, 1835 (Coleoptera: Ptinidae: Xyletininae) from Jordan

Four new species of the genus Lasioderma from Jordan are described: L. parvipenne sp.n. Beetles brown almost wholly, ventral surface blackish, antennae yellow. Pubescence appressed. Surface with uniform punctation. Eyes round. Antennae: 3rd segment as long as the 2nd one; 3–4th segments with oblique anterior margin and straight lateral one; 5–10th segments with convex lateral margin. Pronotum 1.5–1.6 times as wide as long, without posterior angles; pubescence not parted to two sides on pronotal disc; lateral margins slightly flattened. Elytra 1.3–1.4 times as long as wide. Anterior rims   of metasternum are not approximated in the middle. Fore tibiae dilate towards their apices. First seg- ment of hind tarsus 1.4 times as long as the 2nd one. Aedeagus: internal penial sac with 2 small, 2 large, and 1 rather small spines. Pseudopositor: styles as conjugate papillae. Length 2.4–2.9 mm. The new species differs from closely related species by long 2nd tarsimere (from L. serricorne) and lon- ger elytra (from L. quasiquadratum). L. quasiquadratum sp.n. Beetle rufous, shining, antennae light yellow. Pubescence appressed. Surface with dual punctation. Eyes round. Antennae: 3rd segment 1.5 times as long as the 2nd one. 3–4th segments with oblique anterior margin and straight lateral one; 5–10th segments with convex lateral margin. Pronotum 1.45 times as wide as long, without posterior angles, with flattened lateral margins; pubescence not parted to two sides on pronotal disc. Elytra 1.2 times as long as wide. Anterior rims of metasternum are approximated in the middle, 1st rim slightly curved forward. Fore tibiae dilate towards their apices. First segment of hind tarsi 1.9 times as long   as the 2nd one. Aedeagus: internal penial sac with 2 large and 3 of medium-sizes spines. Length 2.25 mm. The new species differs from all other species by short elytra. L. querceum sp.n. Beetle brown, elytral apices, antennae, and legs yellow. Pubescence appressed. Surface with dual punctation. Eyes round. Antennae: 3rd segment as long as the 2nd one; 3–5th segments with oblique anterior margin; 3–8th segments with straight, 9–10th segments with convex lateral margin. Pronotum 1.4 times as wide as long, without posterior angles, lateral margins flattened, pubescence parted to two sides on disc. Elytra 1.46 times as long as wide. 2nd anterior rim of metasternum is slightly curved forward. Fore tibiae dilate towards their apices. First segment of hind tarsi 3 times as long as the 2nd one. Ae- deagus: internal penial sac with 7 large spines. Length 2.3 mm. The new species differs from similar species by surface with dual punctation (from L. exiguum, L. klapperichi, L. redtenbacheri), by short 2nd tarsimere (from L. ronkayi, L. szalokii), by large eyes and monochromatic dorsal surface (from L. thoracicum). L. vescum sp.n. Head, scutellum, antennal ends, and ventral surface black, elytral api- ces rufous, the rest parts dark brown. Pubescence appressed. Eyes round. Antennae: 3rd segment 1.5 times as long as the 2nd one; 4–5th segments with oblique, concave anterior margin, 3–5th segments with straight lateral margin, 6–9th segments with slightly convex lateral one. Pronotum 1.4 times as wide as long, with posterior angles; pubescence not parted to two sides on pronotal disc; surface with dual punctation. Elytra 1.5 times as long as wide, surface wrinkled. Anterior rims of  metasternum  are approximated in the middle, 1st rim straightened, 2nd one curved forward. Fore tibiae not dilated towards apices; 1st segment of hind tarsus 1.5 times as long as the 2nd one. Aedeagus: internal penial sac with compound row (5+3) of small spines, 4 large, and 1 of medium-size spines. Length 2.30–2.45 mm. The new species differs from similar species by oblong antennomeres (from L. bubalus), by round eyes (from L. fuligineum).
