(Figs. 12–20)
Diagnosis. Larva. Four setae between coxae II and III, fnBf 4-4-2, fD 65–94, Ta I 169–194, Ti III 245–296, σI placed at κ, both distally located on genu I.
Description. Larva. Dorsal side of idiosoma with 94 weakly barbed setae in holotype (65–83 in other specimens). One pair of eyes placed at level of posterior margin of scutum. Scutum wider than long; anterior border slightly concave, posterior margin with small concavity. Three pairs of scutalae with short setules, AL longest, ML> PL. Anterior sensillae (ASE) ciliated on their distal ¼ length, placed between bases of AL and ML. Posterior sensillae (PSE) ciliated on their distal ¼ length, longer than ASE (Fig. 12).
Ventral side of idiosoma with a pair of setae 1a placed between coxae I, setae 2a placed between coxae II and four setae placed between coxae III; all these setae with setules. Beyond coxae III 38 barbed setae in holotype (25– 50 in other specimens). NDV = 132 holotype, 93–133 in other specimens. Setae 1b, 2b’, 2b’’, 3b’, 3b’’ located on coxae I, II, III, respectively; all barbed.
Gnathosoma ventrally with ciliated hypostomal setae bs and shorter than other nude hypostomal setae as (Fig. 13). Dorsally a pair of nude adoral setae cs. Pedipalp formula: O-B-B-BBB-BBBNNωζ. Palpfemur and palpgenu with one setulose seta. Palptibia with three setulose setae (Fig. 13). Palptarsus with five normal setae: two long setae and three short setae (one of them distinctly longer than remaining ones), one solenidion placed in proximal part of segment and one eupathidium placed in distal part of palptarsus (Fig. 14).
Leg setal formula: Leg I: Ta 1ω, 2ζ, 26 (22–30); Ti 2φ, 1κ, 18; Ge 1σ, 1κ, 12; Tf 5, Bf 4, Tr 1, Cx 1 (Fig. 15– 16). Leg II: Ta 1ω, 2ζ, 23 (24–30); Ti 2φ, 18 (17–19); Ge 1κ, 12; Tf 5; Bf 4: Tr 1; Cx 2 (Fig. 17–18). Leg III: Ta 1ζ, 25 (25–30); Ti 1φ, 18 (17–19); Ge 12; Tf 5; Bf 2; Tr 1; Cx 1 (Fig. 19–20). σI placed at κ, both located distally on genu I.
Leg lengths: Leg I 874 holotype, 819–927 other specimens; leg II 791, 764–890; leg III 955, 921–1084. IP = 2620 holotype, 2513–2901 other specimens.
Measurements are given in Table 2.
Material. 38 larvae from Z. variegatus, 6 October 2012, Zamakoe (3º34’44’’ N, 11º39’33’’ E) and Mbankomo (3º52’13’’ N, 11º29’42’’ E), Cameroon; collector S. Kekeunou; one larva from Eupezus rufipes, Bagomojo, Cameroon, date and collector unknown.
Remarks. To date this species was known only from Madagascar and was obtained from undetermined Orthoptera (Haitlinger 2007a). All specimens of C. justynae from Cameroon were obtained from Z. variegatus, excluding one specimen obtained from Eupezus rufipes (Coleoptera: Tenebrionidae). It is the second record of Charletonia from Tenebrionidae. Previously C. aerolata was found on undetermined Tenebrionidae (Beron 2008). Specimens of C. justynae from Cameroon differ from specimens of C. justynae from Madagascar in some characters, especially in 2b’, fD and fV (Table 2). Tarsi I–III indicate high variability in the number of normal setae (Ta I 22–30, Ta II 24–30, Ta III 24–30); also tibiae II and III have a variable number of setae. These facts indicate that both characters, especially number of normal setae on all tarsi, have unimportant taxonomic value and should not be used in keys as for example by Khanjani et al. (2012).
Charletonia justynae belongs to the species group with four setae between coxae II–III, Ta I 160–200 Μm, and Ti III 240–310 Μm. This group includes: C. adellae Haitlinger, 2007, C. arlettae Haitlinger, 1987, C. falcata Southcott, 1966, C. oudemansi Southcott, 1966 and C. barbata Southcott, 1966 (Southcott 1966; Haitlinger 1987, 2007a). Moreover, partly these dimensions are shared with C. aerolata (Trägårdh, 1908), C. enghoffi Southcott, 1991 and C. beninensis Haitlinger, 2007 (Trägårdh 1908; Southcott 1991; Haitlinger 2007b). It differs from C. adellae in the longer PsFd (74–90 vs. 62–74) and σI placed at microseta κ, both distally located on genu I and beyond normal setae vs. σI placed relatively far from microseta κ and before three last normal setae and famulus ε on Ta I present vs. famulus ε on Ta I absent; from C. arlettae in the shorter ML (61–69 vs. 70–86), PL (51–63 vs. 66–72), 1a (37–52 vs. 54–64), longer Ta I (169–194 vs. 160), Ti I without seta Cp vs. Ti I with seta Cp, palptarsus with 3B, 2N normal setae vs. 4N normal setae; from C. falcata in the shorter MW (85–108 vs. 119), PW (107–124 vs. 136), ISD (64–74 vs. 89), L (100–115 vs. 133), W (112–136 vs. 140), Ti I (193–244 vs. 289), Ti III (245–296 vs. 310) and fD (65–94 vs. 44); from C. oudemansi in the longer L (100–115 vs. 77–92), AP (45–54 vs. 33–37), Ta I (169–194 vs. 158), shorter 1a (37–52 vs. 85) and 1b (72–100 vs. 110); from C. barbata in the longer AL (72–82 vs. 56–65), ML (61–69 vs. 47–58), 3b’’ (51–68 vs. 43), shorter Ti I (193–244 vs. 256), TiIII (245–296 vs. 317), Ti I without Cp vs. Ti I with Cp and cs nude vs cs barbed; from C. aerolata in the longer PW (107–124 vs. 91–103), W (112–136 vs. 101–111), AL 72–82 vs. 38–55), ML (61–69 vs. 40–53) and Ta I (169–194 vs. 140–172); from C. enghoffi in the shorter ISD (64–74 vs. 73–77), ASE (52–70 vs. 70–75), PSE (79–110 vs. 116–129), 1a 37–52 vs. 69–75), longer Ta I (169–194 vs. 156–164), Ta II (154–188 vs. 131–149), Ta III (171–195 vs. 153–167) and σI placed distally to most distal normal setae vs. σI placed proximally to most distal normal setae and from C. beninensis in the longer AL (72–82 vs. 66–70), Ta I (169–194 vs. 156–170), Ta II (154–188 vs. 150–156), Ta III (171–195 vs. 162–174), IP (2513–2906 vs. 2346–2552), palptarsus with 3B, 2N normal setae vs. palptarsus with 4N normal setae, tarsus I with famulus ε vs. tarsus I without famulus ε, Ti I without Cp vs. Ti I with Cp, fn Ta II (23–30 vs. 20), fn Ta III (25–30 vs. 21) and anterior border straight vs. anterior border slightly concave.
