Štusák, J. M.: Two new species of Pneustocerus Horváth, 1905, with a list of already known species (Heteroptera, Berytidae)

times longer than 4th, 3rd segment 2.5 times longer than 4th. Fourth segment narrowly spindle-shaped and moderately wider than clava of 1st segment, which is a little more than twice as wide as remaining portion of 1st segment. Antennae unicoloroushy light rusty brown, without spots or points, base and apical clava of 1st segment being the lightest (light rusty yellowish), last 1/4 of 1st segment (before the clava) darkest (dark brown). Fourth segment with its basal portion black, apical portion (a little less than half) whitish. Antennae with tiny whitish hairs which are shorter than diameter of the segments. Rostrum lacking in the holotype. Pronotum 1.4 times longer than its median width and moderately longer than 4th antennái segment. Anterior margin of pronotum convex, posterior margin only moderately but widely concave. Anterior pronotal lobe occupies almost 1st third of pronotal length (32%), its anterior portion (about one half) is areolated (with two complete and one incomplete rows of areolae), posterior portion of anterior pronotal lobe is occupied by one unpaired callosity which is very convexly vaulted upwardly and shiny. Pronotal carinae very slightly developed, median carina beginning beyond the callosity is well marked only in first half of posterior pronotal lobe. Humeral elevations very low, median elevation a little higher. Posterior lobuli of pronotum almost absent. - Scutellum wider than long, armed with spine which is wide at base, its base occupying almost posterior half of scutellum. The spine is sharply pointed to its apex and is only moderately shorter than half the length of posterior margin of pronotum. Posterior scutellar margin roundly convex (almost arch-like). -Supracoxal lobes I rather convex sideways so that they are visible also from dorsal view. Ostiolar process very long and considerably reaching beyond level of hemelytra, similarly as in the others species of Pneustocerus. Its ostiolar canal including inner apex piceous. Apex of the ostiolar process backwardly bent, inner portion of the apex is convexly vaulted upwardly and only indistinctly reaching beyond the hem of the lateral margin of the ostiolar apex. Areolation of supracoxal lobes II and III inexpressive. Hemelytra with light ochreous veins on corium which is unpunctured among veins, transparent and of similar quality as membrane. Hemelytra shorter than abdomen, reaching at base of 7th tergite in male. Inner margin of prolonged portion of corium with dark line. - Abdomen unpunctured, light ochreous ventrally, mediotergites darker blending to rusty brown, laterotergites lighter ochreous. Mediotergites very finely transversely wrinkled and glossy. Mediotergites 3+4+5+6, sternites 3+4+5 fused in male. Sulcus between mediotergites 5 and 6 is well marked but fused immobilely. Mediotergites as well as sternites with very fine, short and not too dense hairs occurring at most on the portion of 7th tergite which is not covered by hemelytra. A rudiment of fissure of dorsal abdominal gland visible between 3rd and 4th mediotergites. Trichobotriae on 3rd and 4th sternites (3+3) as usual, but also on 5th, 6th and 7th sternites (2+2) in posterior thirds of the sternites laterodorsally. These trichobotriae are much shorter (about half the length) than those of 3rd and 4th sternites. -Legs very long and light ochreous including coxae and trochanters, apical clavae of femora even lighter blending to rusty. Only lateroventral portions of femora with tiny, convex, dark points in their basal third. Whole femora with hairs measuring about 1/3-1/2 of width of the femur. Except this, legs including apical clavae of femora without dark points. Apices of tibiae enlarged and dark, tarsi dark brown. First tarsal segment occupies 2/3 of tarsal length, i. e. it is twice longer than 2nd and 3rd. Second tarsal segment moderately shorter than third. Posterior femora considerably reaching beyond apex of abdomen (almost by 1/4 of length of the femur in male). - Measurements in mm: length of body 6.79, maximal width of body (hemelytra) 1.02, length of head 0.62, width of head 0.64, distance between eyes 0.40, length of antenna 14.29 (I:II:III:IV = 6.72:3.83:2.68:1.06), length of pronotum 1.28, width of pronotum 0.94, length of hemelytron 4.38, width of hemelytron 0.94, length from end of pronotum to apex of abdomen 4.89, length of legs: leg femur tibia tarsus anterior 3.91 4.34 0.64 middle 4.34 4.80 0.68 posterior 6.12 8.42 Holotype, male: New Guinea, Papua, Wau, 20.IX.1972, M. cs. [=MaIaise trap], leg. L. MÓCZÁR. It is deposited in the Hungarian Natural History Museum, Budapest. Distinguishing features: The differences between Pneustocerus vicinus sp. n. and all the hitherto known species of the genus are as follows: It differs from P. nigricornis HORVÁTH, 1905 (New Guinea), P. brevispina HORVÁTH, 1922 (Kalimantan, Philippines) and P. malayanus sp. n. (Malaya) in having whole antennae (except 4th segment) and whole legs light coloured (in difference from above mentioned species where antennae and legs are either completely black or major portion of them is piceous); it also differs in different lengths and proportions of antennái segments, dif-
