Lis, Jerzy A. & Lis, Barbara, 2010, Teabooma secunda (Hemiptera: Heteroptera: Cydnidae) — a new species of a New Caledonian endemic genus, with a redescription of T. princeps Distant, Zootaxa 2543, pp. 64-68 : 67

Teabooma secunda sp. nov.

( Figs 2 , 4, 5, 7, 9)

Description (submacropterous forms only): Body shiny; head, pronotum and scutellum black or almost black, corium more brownish in shade; female generally darker than males. Head vestiture as in T. princeps ; the whole anterior margin of head slightly sinuate (in T. princeps margins almost straight); clypeus as long as the paraclypei, its surface impunctate, with a few more or less visible striae; puncturation of paraclypei weaker than that of T. princeps , and not reaching the lateral clypeal margins (Fig. 4); paraclypeal punctures somewhat larger than those of preceding species. Ocular index 3.6–4.2. Antennae four-segmented, pale brown or brown, the second segment longest; 1st and 2nd segment a little darker than the remaining segments. Rostrum pale brown or brown, surpassing the coxae of posterior legs and reaching, or almost reaching, the posterior margin of first visible abdominal segment. Gular plates punctured, especially close to bucculae, with large coarse punctures.

Pronotal disc, except calli, coarsely punctured, but its puncturation coarser and deeper ( Fig. 2 ) that that in T. princeps ; calli impunctate, larger and more elevated than those of the preceding species; pronotal lateral carinae and vestiture as in T. princeps . Male posterior pronotal margin close to postero-lateral angles with more or less visible yellowish brown patch; female pronotum without yellowish patches. Scutellum long; its disc with puncturation coarser, but weaker than that in T. princeps . Corium almost evenly punctured, the puncturation coarser than that in T. princeps ; clavo-corial suture almost indistinct, meso-exocorial suture also incomplete. Exocorium with lateral part clearly uprised along more than a half of its length. Costa narrow, convex, without setigerous punctures. Hemelytral membrane from pale brown to brown, only a little shorter and narrower than the abdomen, membranal veins distinctly visible. Propleuron shiny, its depression with large coarse punctures. Evaporative areas large (Fig. 5), that of mesopleuron with large, deep punctures; peritremal apex as in Fig. 5. Coxae and femora black or blackish brown, tibiae and tarsi brown or pale brown, tibial spines almost black.

Abdominal sterna glossy in the middle, their sides punctured; sternal postero-lateral angles with small or without projections ( Fig. 2 ).

Aedeagus with 2nd conjunctival appendages long, distinctly projecting out (Fig. 9); male genital capsule and paramere (Fig. 7) similar to those of T. princeps (Fig. 6).

Measurements (in mm, males and female respectively): body length 17.56-19.22, 19.12; body width 9.95-11.02, 11.32; head length 3.32-3.51, 3.32; head width 4.68–5.07, 4.98; pronotum length 5.66–5.85, 5.85; pronotum width 8.46–10.54, 10.24; scutellum length 6.73–7.41, 7.61; scutellum width 5.95–6.05, 6.24; antennal segments: (1st) 0.85–1.22, (2nd) 2.49–3.01, (3rd) 1.95–2.19, (4th) 2.19; (1st) 1.10, (2nd) 2.68, (3rd) 1.98, (4th) missing.

Type material: Holotype male: New Caledonia, 9961, 22 0 06’S x 166 0 39’E, Riv. Bleue, Panoramic track, 20ix–11xi 2000, Monteith & Skevington, Pitfall, 160m (Queensland Museum, Brisbane, Australia). Paratypes: 1 male: New Caledonia, Mt Rembai, 650m, 9 May, 1984, G. Monteith & D. Cook (Queensland Museum, Brisbane, Australia); 1 female: Nouvelle Calédonie, Pic d’Amoa, 21.II.1993, M. Boulard, réc., Montagne de Povilla, Muséum Paris (Muséum National d’Histoire Naturelle, Paris, France).

Diagnosis: This new species can be separated from T. princeps by its different general body habitus (body more ovate and dorsally shiny in T. secunda— Fig. 2 ; body more elongate and dorsally almost entirely alutaceous in T. princeps— Fig. 1 ); its dorsal puncturation (weaker, deeper and coarser in T. secunda ( Figs. 2 , 4), than in T. princeps ( Figs 1 , 3)), and, by the length of the 2nd conjunctival appendages of aedeagus, which are larger and longer in T. secunda (Fig. 9) than in T. princeps (Fig. 8). Moreover, both species differ in the length of the rostrum (rostrum surpassing the posterior coxae and reaching or almost reaching the posterior margin of first visible abdominal segment in T. secunda , in contrast to the rostrum reaching between the median and posterior coxae, sporadically surpassing the posterior coxae and reaching at most the anterior margin of the 1st visible abdominal segment in T. princeps ). Additionally, T. secunda differs from T. princeps in body length and width (see the measurement data to each species) to mention particularly that T. secunda is longer and wider than T. princeps .
