Physopelta (Neophysopelta) redeii sp. nov.

( Figs 39–40 View Figs 38–41. 38 )

Type locality. Thailand, Nan Province, Doi Phu Kha National Park.

Type material. HOLOTYPE: ♂, ‘ Thailand Doi Phuka / N.P. at ligth, 3.xi.2004 / A.Orosz, M.Földváry / & L. Papp’ [p white label] // ‘Holo- / typus’ [p, red label with black frame submarginally] // ‘ Physopelta / redeii / sp. n. [hw, underlined] / J.L. Stehlik det. [p] 2008 [hw]’ [red label with black frame] ( HNHM). The holotype is pinned on a black-enameled pin with head; left antennomere 4, left metatarsus, and right mesotarsus missing. PARATYPES: 2 ♀♀, the same data as holotype (1 ♀ HNHM, 1 ♀ MMBC).

Description. Colouration ( Figs 39–40 View Figs 38–41. 38 ). Head, antennae (except ca. basal half of antennomere 4), callar lobe (except lateral margins), pronotal lobe, central and apical spot on corium, membrane, labium, thoracic sterna, legs, and abdominal sternites black. Lateral margins of pronotum, callar lobe laterally, posteriorly, and medially, posterior pronotal margin, scutellum, clavus, corium, pronotal epipleuron, and ventral and dorsal laterotergites, orange. Basal half of antennomere 4 whitish. Black central spot on corium smaller, situated between cubitus and media; posterior spot oval, not prolonged to apex of corium.

Pilosity. Body dorsally, sternites, and tibiae covered with silvery pubescence. Tibiae in both sexes with semierect black spines.

Punctation. Callar lobe laterally emarginated with black punctures; entire disc of pronotal lobe with dense, very distinct black punctures; punctures on scutellum less distinct, developed on entire surface of clavus and on corium (except its costal margin).

Structure. Pronotum sexually dimorphic: in male callar lobe strongly gibbose with lateral margins not insinuated medially; in female callar lobe weekly gibbose with lateral margins slightly insinuated medially and distinctly widening posteriorly ( Fig. 39 View Figs 38–41. 38 ). Labium reaching mesocoxae. Male profemora ventrally with longitudinal furrow developed along its entire length, on ventral margin of the furrow with 8 remote teeth, on dorsal margin apically with three small denticles, one large tooth, and close to it another very large, curved, and apically indented tooth. Male protibiae in apical two-thirds with distinct denticles on ventral surface. Meso- and metafemora in male ventrally with a row of small denticles along their entire length. Females with teeth on profemora reduced compared to male, ventral margin of longitudinal furrow only with very small denticles, on dorsal margin with two large and somewhat remote straight teeth, the more apical one being larger. Protibiae, meso- and metafemora of females ventrally without denticles.

Measurements (in mm). Male (holotype). Body length 15.28; head: width (including eyes) 2.21, interocular width 1.30; lengths of antennomeres: 1 – 2.48, 2 – 2.70, 3 – 1.84, 4 – 2.81; pronotum: length 3.40, width 5.13; scutellum: length 2.16, width 3.02; corium: length 7.49, width 2.97.

Females (n = 2). Body length 15.07 / 15.12; head: width (including eyes) 2.27 / 2.32, interocular width 1.40 / 1.30; lengths of antennomeres: 1 – 2.32 / 2.32, 2 – 2.59 / 2.70), 3 – 1.67 / 1.84, 4 – missing / 2.46; pronotum: length 2.86 / 2.70, width 5.24 / 4.86; scutellum: length 2.43 / 2.43, width 2.97 / 3.02; corium: length 7.40 / 8.21, width 2.92 / 2.97.

Differential diagnosis. Physopelta redeii sp. nov. most resembles Ph. kotheae distributed in Sumatra and Java. However, Ph. kotheae is smaller (♂♂ 12.80–14.84 mm, ♀♀ 13.55–14.63 mm) than the new species, its antennomeres are shorter, lateral margin of pronotum is narrower, callar lobe is distinctly gibbose in both sexes, meso- and metafemora are ventrally provided with a series of denticles in both sexes, lateral margins of pronotum and costal margins of corium are whitish, black central spot on corium is larger (laterally reaching nearly to costal margin), approaching the apical black spot, and body is dorsally covered by erect black hairs. In contrast, Ph. redeii sp. nov. is larger (♂ 15.28 mm, ♀♀ 15.07–15.12 mm), its antennomeres are longer, lateral margin of pronotum is wider, callar lobe is sexually dimorphic (only slightly gibbose in female), meso- and metafemora are provided ventrally with a series of denticles only in males but unarmed in females, lateral margins of pronotum and costal margins of corium are orange, black central spot on corium is smaller, more remote from the apical black spot, and body is dorsally covered by silvery pubescence. In colouration the new species resembles Jindraia dimorphica , but differs from the latter species by the characters given in the key to genera (see above).

Etymology. I name the new species in honour of Dávid Rédei (Hungarian Natural History Museum, Budapest), a young heteropterist and specialist of the family Reduviidae .

Distribution. Northern Thailand (this paper).
