蛛缘蝽科

蛛缘蝽科（学名：Alydidae），又名蛛缘椿象科，是半翅目缘蝽总科下的一个科。本科物种与缘蝽科物种有着密切关系。现时本科包括有至少50个属、 290个物种。
分布于温带及地区上较温暖的地区，本科物种主要为热带及亚热带昆虫。举例说：在欧洲本科有10个属的物种，当中只有2个属有在较温暖的地中海区域以外出现。

**型态描述**
一只见于喀拉拉邦的Riptortus属物种。
Broad-headed bugsYiu 2012 are up to 1 long, and have slender bodies. Some have long and very thin legs. The most notable characteristics of the family are that the head is broad, often similar in length and width to the 前胸 (昆虫) and the , and that the last 触角 segments are elongated and curved. The 复眼s are globular and protruding, and they also have . The 腿 (节肢动物) of the hindlegs bear several strong spines; the tarsus has three segments. Most species have well-developed 翅鞘 (forewings), allowing them to fly well, but in some the hemelytra are vestigial. The membranous part of the hemelytra have several closely spaced long veins.
Alydidae are generally of dusky or blackish coloration. The upperside of the 腹 is usually bright orange-red. this color patch is normally not visible as it is covered by the wings; it can be exposed, perhaps to warn would-be 捕食s of these animals' noxiousness: They frequently have scent glands that produce a stink considered to be worse than that of true stink bugs (蝽科). The stink is said to smell similar to a bad case of 口臭.
Sometimes the adults have  reduced wings. Both, nymphs and adults of some species, such as  and  spp. are 拟蚁现象s and live in ant nests.

**栖息地与生态**
这些昆虫主要栖息于相当干旱的沙质栖息地，见于海滨、石楠荒原、干草原和疏林草原。牠们的主要以植物的种子为食：牠们会用其长鼻刺穿种子，以饮用其中所含的营养液。部分物种在经济上是重要的害虫，例如水稻上的。

**分类**
本科物种为单源群Li & Zheng，可分为三条自然的家系。这三条家系原来对应本科的三个族，分别如下Li & Zheng：- 蛛缘蝽族（Alydini）、- 稻缘蝽族（Leptocorisini）和- 微翅缘蝽族（Micrelytrini）。
1965年，有两份文献对这分类作出不同的修订：- Ahmad (1965) Ahmad 1965将三个族都提升至亚科级，分别为ITIS_108249：
** 蛛缘蝽亚科 Alydinae
** 稻缘蝽亚科 Leptocorinae
** 微缘蝽亚科 Microelytrinae- 而Schaefer (1965)的提议将本科物种只分为两个亚科Schaefer 1965：
** 蛛缘蝽亚科不变；
** 稻缘蝽族（Leptocorisini）与微翅缘蝽族（Micrelytrini）合组成为微缘蝽亚科。
中国昆虫学家李新正和郑乐怡于1993年发表研究，对蛛缘蝽科各个亚群合共16个代表属作比较形态学研究，结论认同Schaefer (1965)的分类建议才符合研究结果Li & Zheng。其后，Schaefer (1999)Schaefer 1999再完善整个分类。不过，Ahmad (1965)的分类仍然有文献在使用。
