Studies and reports of District Museum Prague-East Taxonomical Series 3 (1-2): 149-170, 2007 New species of the genus Hymenalia Mulsant, 1856 (Coleoptera: Tenebrionidae: Alleculinae) from Palaearctic region Vladimír NOVÁK District Museum Prague-East Masarykovo nám. 97, CZ-250 01 Brandýs nad Labem e-mail: [email protected] Taxonomy, new species, new combinations, description, distribution, key, Coleoptera, Tenebrionidae, Alleculinae, Hymenalia, Palaearctic region. Abstract. Hymenalia alenae sp. n. from Yemen, Hymenalia genuensis sp. n., Hymenalia iranica sp. n. and Hymenalia lalai sp. n. from Iran and Hymenalia jakli sp. n. from Oman and Yemen are described, keyed and illustrated. New combinations of Hymenalia brignolii (Muche, 1974) comb. n. - removed from genus Allecula and H. denticulata (Muche, 1982) comb. n. - removed from genus Prionychus after studying type material. New distributional data of Hymenalia denticulata (Muche, 1982) from United Arab Emirates are added. INTRODUCTION In 1856, Mulsant has described new genus Hymenalia. Borchmann (1910) in Coleopterorum Catalogus listed only 11 species of this genus and 15 species were listed by Mader (1924) in Catalogus coleopterorum regionis palaearcticae. Till the present time, 31 species of this tenebrionid genus have been described from the Palaearctic region (Novák 2008). In 1975, Dubrovina has described new subgenus Nikomenalia and divided the remaining species of the genus into 3 groups. Key to groups and new subgenus according to Dubrovina (1975) is translated from Russian and added. Into first group Dubrovina included the species Hymenalia badia Kiesenwetter, 1861, H. basalis Faust, 1877, H. crassicollis Fairmaire, 1866, H. elongata Pic, 1925, H. obscuriceps Pic, 1925, H. obscuripennis Pic, 1905, H. reticulata Seidlitz, 1896 and H. purkynei Obbenberger, 1917. All new species from Asia, which belong to the first group by Dubrovina (1975) - Hymenalia alenae sp. n. from Yemen, Hymenalia genuensis sp. n., Hymenalia iranica sp. n. and Hymenalia lalai sp. n. from Iran and Hymenalia jakli sp. n. from Oman and Yemen, are described, keyed and illustrated. New combinations of Hymenalia denticulata (Muche, 1982) comb. n. (removed from the genus Prionychus after studying type material) and Hymenalia brignolii (Muche, 1974) comb. n. (removed from the genus Allecula after studying type material) are added and a new distributional data of the species Hymenalia denticulata are given. MATERIAL AND METHODS Collections from Iran (Hymenalia genuensis sp. n., H. iranica sp. n. and H. lalai sp. n.) were obtained during three expeditions of National Museum of Prague between 1970 and 1977. 149 Part of the material of the species Hymenalia iranica sp. n. and Hymenalia lalai sp. n. was collected in Iran in 1998, 2002 and 2004 by P. Kabátek. Material of the species Hymenalia jakli sp. n. were collected mainly by S. Jákl in Oman in year 2003 and second part in south Yemen 2005 by P. Kabátek. Last, Hymenalia alenae sp. n. was collected in south and west Yemen in 2005 by P. Kabátek. Type specimens of Hymenalia (Prionychus) denticulata Muche, 1982 comb. n. and H. (Allecula) brignolii Muche, 1974 comb. n. were loans from Staatlisches Museum fur Tierkunde Dresden, Germany. Specimens of the species H. denticulata from United Arab Emirates were collected by A. van Harten. Two important quotients are used for descriptions of species of subfamily Alleculinae - „ocular index“ dorsaly (Campbell & Marshall, 1964) and „pronotal index“ (Campbell, 1965). Specimens of the presently described species are provided with one red label printed: „Hymenalia alenae sp. n. or Hymenalia genuensis sp. n. or Hymenalia iranica sp. n. or Hymenalia jakli sp. n. or Hymenalia lalai sp. n.

Description of holotype. Body elongately oval; length 5.03 mm, 2.81 times longer than wide; widest at two third of elytral length. Head (Fig. 9). Brown, clypeus samewhat lighter. Eyes large, broadly transverse, dark and strongly excised, vertex between eyes narrow. Widest across eyes 0.89 mm (0.63 of pronotal base width). Lenght of head (visible part) 0.87 mm. Ratio L/W (length/maximum width) 0.98. Ocular index 15.27. Head with relatively sparse short light setation, only after eyes near base setation darker, setation of clypeus longer. Densely and shallowly punctuated; punctures large, with microsculpture, matt; apical part of head and interspaces of clypeus shiny. Antennae (Fig. 10). Shorter (reaching only 0.46 of body length) 2.31 mm. All antennomeres universally light brown, matt, only antennomeres first and second slightly shining. Second antennomere shortest, eleventh antennomere longest, from fourth to tenth antennomeres distinctly serrate and mostly longer than third antennomere. Antennomeres 157 with light setation, slightly rugulose and with light punctures. Ratios of relative lengths of antennomeres from base to apex as follows: 0.61: 0.48: 1.00: 1.08: 1.06: 1.10: 1.04: 0.94: 0.97: 1.04: 1.32. Ratios L/W (length/maximum width) for antennomeres from base to apex as follows: 1.42: 1.50: 2.72: 2.15: 2.13: 2.08: 1.61: 1.72: 1.93: 2.00: 3.24. Maxillary palpus. Light brown, as colour as antennae, palpomeres with light setation, slightly shining. Ultimate palpomere broadly longely triangular, penultimate and ultimate palpomeres distinctly broadest on apex, narrowest at base. Penultimate palpomere distinctly shorter than second and ultimate ones. Ratios of relative lengths of palpomeres from second to fourth from base to apex as follows: 1.65: 1.00: 3.76. Ratios L/W (length/maximum width) of palpomeres from second to fourth from base to apex as follows: 2.75: 1.06: 1.19. Pronotum (Fig. 9). Brown, matt, slightly transverse, slightly elongate, not quite semicircular, with light setation directed backwards. Slightly narrower than elytra, longest through the middle 1.01 mm. Widest at base 1.42 mm. Pronotal index 71.38. Pronotal margins conspicuous and complete at all sides. Pronotal base slightly excised in outer thirds, straight against scuttelum. Posterior angles right-angled, anterior angles not distinct. Sides of pronotum straight at basal half, in apical half regularly rounded. Surface densely and shallowly punctuated, punctures large and close together, interspaces very narrow. Pronotum matt, spaces inside punctures rugosed. Scutellum triangular, brown, as coulour as elytra and pronotum. Ventral side of body. Thorax brown, as colour as elytron, with light setation and middle-sized punctuation. Abdomen five segmented, lighter than thorax, with very fine microsculpture, sparser light setation, without distinct punctuation. Elytron. Universally brown with light, relatively short and dense setation, setae directed backwards. Slightly broader at base than pronotum, very slightly longely oval. Elytral length 3.13 mm. Widest at about two thirds of its length, measured from base; at this place elytral width 1.79 mm. Elytra 1.75 times longer than wide. Elytral striae not clearly conspicuous, diameter of punctures in elytral striae larger than diameter of punctures in elytral interspaces. Punctures not as dense as those of pronotum. Surface with microsculpture, only very slightly shining, rather matt. Elytral epipleura samewhat lighter brown (as elytron itself), well developed; in basal half parallel, thence regularly narrowed to first abdominal sternite. In apical half parallel again and then rounded apically. Epipleura with small sparse punctures bearing light setae each; in apical part setation denser and setae as long as on elytra. Row of large punctures at basal half of epipleura present, at apical half larger punctures absent. Legs. Longer, universally light brown, lighter as elytron covered with short and relatively dense setation. Femora strong, tibia very narrow; widest at apex, narrowest at base. Penultimate tarsomere of each tarsus with membranous lobes as wide as tibia at apex. Ratios of relative lengths of tarsomeres from base to apex as follows: protarsus: 1.00: 0.63: 0.51: 0.82: 2.01; mesotarsus: 1.00: 0.46: 0.30: 0.49: 0.86; metatarsus: 1.00: 0.39: 0.28: 0.60. Aedeagus (Figs 11, 12). Light yellowish brown, slightly shining, basal piece regularly narrowed to apex. Apical piece longely triangular with very narrow rounded apex. Ratio of length of apical piece to length of basal piece 1: 2.44. Male (Figs 8-12). Both anterior tarsal claws with 10 visible teeth. 10 males: length 5.21 mm approximately (ranging from 4.87 to 5.89 mm); head length 0.89 mm approximately (ranging from 0.79 to 1.09 mm); head width 0.94 mm approximately 158
