Charletonia cameroonensis Haitlinger & Kekeunou sp. nov.

( Figs. 1–11 )

Diagnosis. Four setae between coxae II and III, fD 90–92, fV 30–34, NDV 120–126, Ta I 226–237, Ti I 335–363, Ti III 412–444, fn Bf 4-4-3.

Description. Larva (Holotype). Dorsal idiosoma with 92 (90–92) weakly barbed setae. One pair of eyes, cornea 23 x 21 ( Fig. 1 ). Dorsal scutum punctate, a little wider than long (in two paratypes distinctly wider than long, in one paratype longer than wide), anterior border concave, posterior border slightly concave. Three pairs of scutalae (AL>ML>PL), all slightly barbed. Two pairs of sensillae with fine setules in distal half only ( Fig 3 ).

Venter of idiosoma bears a pair of setae between coxae I, a pair of setae between coxae II, four setae between coxae II and III and 34 (30–32) setae behind coxae III; all setae setulose. Coxalae setulose, coxalae 1b longer than other coxalae ( Fig. 2 ).

Gnathosoma. Galeala (cs) spiniform, nude, anterior hypostomala (as) nude, over twice shorter than posterior hypostomala (bs), bs with relatively long setules. Palpfemur and palpgenu each with one barbed seta, palptibia with three barbed setae. Odontus divergent ( Fig. 4 ). Palptarsus bears five normal setae, two covered with setules, three smooth (two are long 55 and 58), and one proximal solenidion and distal eupathidium ( Fig. 5 ). Supracoxal peg-like seta present (eP).

Leg setal formula: Leg I: Ta 1ω, 1ε, 2ζ, 29 (25–29); Ti 2φ, 1κ, 18, Ge 1σ, 1κ, 12, Tf 5, Bf 4, Tr 1, Cx 1 ( Figs. 6, 7 ). Leg II: Ta 1ω, 2ζ, 23 (26–27); Ti 2φ, 18; Ge 1κ, 12; Tf 5; Bf 4; Tr 1; Cx 2 ( Figs. 8, 9 ). Leg III: Ta 1ζ, 26 (24– 26); Ti 1φ, 18 (18–19); Ge 12; Tf 5; Bf 3; Tr 1; Cx 2 ( Figs. 10, 11 ).

Leg lengths. Leg I 1339 holotype, 1278, 1236, 1333 paratypes, leg II 1206, 1129, 1137, 1184, leg III 1507, 1413, 1436, 1506. IP = 4062 holotype, 3820, 3809, 4023 paratypes.

Measurements are given in Table 1 .

Etymology. Named after its occurrence in Cameroon.

Type material. All larvae were collected by S. Kekeunou in 7 October 2012 from Z. variegatus . Holotype and 3 paratypes were collected in Zamakoe (3º34’44” N, 11º39’33” E). The holotype is deposited in the Museum of Natural History, Wrocław University and three paratypes are deposited in the Museum of Natural History, Wrocław University of Environmental and Life Sciences, Poland.

Remarks. Charletonia cameroonensis Haitlinger & Kekeunou sp. nov. belongs to the species group with four setae between coxae II and III, Ti III> 320 Μm and Ta I> 190 Μm. This group includes C. dorotae Haitlinger, 1987 , C. taiwanensis Tsai & Chow, 1988 , C. ishii Southcott, 1991 , C. domawiti Haitlinger, 2004 , C. ramoni Haitlinger, 2007 , C. rajmundi Haitlinger, 2007 and C. mehranensis Haitlinger & Saboori, 2007 ( Haitlinger 1987, 2004, 2007a, c; Tsai & Chow 1988; Southcott 1991; Haitlinger & Saboori 2007). Moreover, to this group C. brunni ( Oudemans, 1910) and C. volzi ( Oudemans, 1910) can be included—length of tarsus I and tibia III partly lies in the settled limit for this group.
