Pomphopsilla spinosa Jałoszyński 2024, sp. n.

Pomphopsilla spinosa sp. n. (Figs 1, 4, 7) Type material. Holotype: (TOGO): ♂, three labels: “TOGO PALIME / Forêt de Klouto / 20-24-IV-74 S. Vit ” [white, printed], “ Coll. S. Vit / MHNG - 2021” [white, printed], “ POMPHOPSILLA / spinosa m. / P. Jałoszyński, '24 / HOLOTYPUS ” [red, printed] (MHNG). Paratype: ♂, same data as for holotype except that “Klouto” is crossed out and replaced with handwritten “Kpimé”, and with yellow “ PARATYPUS ” label (MHNG). Diagnosis. Body (Fig. 1) light brown; pronotum and elytra with inconspicuously fine punctures; pronotum with two pairs of antebasal pits, of which inner pair is conspicuously large and subtriangular, anteriorly slightly exceeding 1/3 of pronotal length, outer pits nearly punctiform; aedeagus in ventral view (Fig. 4) with narrowly subtriangular apex and endophallus with lateral groups of strongly elongate pointed sclerites and median tubular structure. Description. Body of male (Fig. 1) strongly elongate, weakly convex, light brown. BL 0.60–0.63 mm. Head broadest at large, strongly convex and coarsely faceted eyes, HL 0.08 mm, HW 0.15 mm; vertex strongly transverse, weakly convex, anteriorly confluent with subtriangular and similarly weakly convex frons; supraantennal tubercles small but distinct; punctures on frons and vertex fine and inconspicuous; setae very short and sparse, recumbent; frontal glands present, each situated behind supraantennal tubercle and near mesal margin of eye.Antenna moderately long, with abruptly broadened club composed of two antennomeres, AnL 0.26–0.28 mm, antennomeres 1 and 2 each elongate, 3 indistinctly transverse, 4–7 each about as long as broad, 8 indistinctly transverse, 9 and 10 each about as long as broad, 11 slightly broader and much longer than 10, indistinctly elongate. Pronotum subrectangular with broadly rounded anterior corners, broadest near anterior fourth; PL 0.18 mm, PW 0.20 mm.Anterior margin nearly straight; anterior corners in strictly dorsal view not visible; lateral margins rounded in anterior third and weakly sinuate in posterior half, indistinctly microserrate; posterior corners obtuse-angled; posterior margin with narrow and rounded emargination in front of mesoscutellum, sides of posterior margin barely noticeably concave; pronotal base with two pairs of pits: inner pair conspicuously large, subtriangular and deep, slightly longer than third of pronotal length and narrowly separated at middle, outer pair much smaller, nearly punctiform, circular. Punctures on pronotal disc inconspicuously fine; setae short, moderately dense, recumbent. Elytra oval, broadest slightly anterior to middle; EL 0.35–0.38 mm, EW 0.26–0.28 mm, EI 1.33–1.36; humeral calli small but distinctly elevated, slightly elongate. Punctures and setae similar as those on pronotum. Hind wings well developed. Legs moderately long and slender, unmodified. Aedeagus (Fig. 4) stout, AeL 0.11 mm; median lobe in ventral view subtriangular, with narrowly subtriangular apex; endophallus with lateral groups of strongly elongate pointed sclerites diverging distally and with median tubular structure; parameres slender, their apices not reaching apex of aedeagus, each with one long apical seta. Female. Unknown. Distribution. Southern Togo (Fig. 7). Etymology. The specific adjective spinosa refers to the long and pointed endophallic sclerites. Remarks. This species is unique in unusually large and subtriangular inner antebasal pronotal pits and this character alone is sufficient to distinguish P. spinosa from all congeners.蓬跳甲属（Pomphopsilla）spinosa 新种（图1、4、7） 模式标本。正模：（多哥）：♂，共3个标签：“TOGO PALIME / 克洛图森林 / 1974年4月20-24日 S. Vit” [白色，印刷]，“S. Vit 采集 / MHNG - 2021” [白色，印刷]，“POMPHOPSILLA / spinosa 新种 / P. Jałoszyński, '24 / 正模” [红色，印刷]（馆藏于MHNG）。副模：♂，采集信息与正模一致，仅“Klouto”被划去并手写替换为“Kpimé”，且附带黄色“副模”标签（馆藏于MHNG）。 鉴定特征。体（图1）呈浅棕色；前胸背板与鞘翅具不明显细刻点；前胸背板具2对基前凹，其中内对显著宽大且呈亚三角形，前端略超过前胸背板长度的1/3，外对近点状；阳茎腹面观（图4）顶端狭亚三角形，内阳茎具侧生的细长尖骨片群与中部长管状结构。 形态描述。雄性体（图1）极度延长，稍呈凸形，浅棕色。体长0.60–0.63 mm。 头部以大而强烈隆起的复眼处为最宽，头长HL 0.08 mm，头宽HW 0.15 mm；头顶强烈横宽，稍隆起，前端与亚三角形、同样稍隆起的额部相连；触角上突小但显著；额部与头顶的刻点细弱且不明显；毛短小稀疏，平伏；额腺存在，分别位于触角上突后方、复眼内侧缘附近。 触角中等长度，棒节突然膨大，由2个触角节组成，触角长AnL 0.26–0.28 mm；触角节1、2均细长，第3节不明显横宽，第4~7节长宽近相等，第8节不明显横宽，第9、10节长宽近相等，第11节略宽于第10节且显著长于第10节，不明显延长。 前胸背板近矩形，前角宽圆，最宽处近前1/4处；前胸背板长PL 0.18 mm，宽PW 0.20 mm。前缘近直；严格背面观不可见前角；侧缘在前1/3呈圆形，后半部弱波状，具不明显的微锯齿；后角呈钝角；后缘在中胸小盾片前方具狭圆凹缺，后缘两侧略凹陷；前胸背板基部具2对凹窝：内对显著宽大，亚三角形且深，略长于前胸背板长度的1/3，中部彼此狭离，外对小得多，近点状，圆形。前胸背板盘区刻点细弱不明显；毛短，中等密度，平伏。 鞘翅卵形，最宽处略近中部前方；鞘翅长EL 0.35–0.38 mm，宽EW 0.26–0.28 mm，鞘翅长宽比EI 1.33–1.36；肩突小但显著隆起，略呈长形。刻点与毛被类似前胸背板。 后翅发育良好。 足中等长度，纤细，无特化。 阳茎（图4）粗壮，阳茎长AeL 0.11 mm；中叶腹面观亚三角形，顶端狭亚三角形；内阳茎具侧生的细长尖骨片群，向远端发散，且具中部长管状结构；阳茎侧突纤细，顶端不达阳茎顶端，各具1根长端毛。 雌性：未知。 分布：多哥南部（图7）。 词源：种加词spinosa意为“多刺的”，指代内阳茎的细长尖骨片。 讨论：本种的独特之处在于具异常宽大且呈亚三角形的前胸背板基前内凹，仅凭该特征即可将刺蓬跳甲（Pomphopsilla spinosa）与所有同属物种区分开来。
